For foreign nationals living in Mexico, freelancers working with international clients, software developers, consultants, and independent professionals, RESICO can represent a significant tax advantage.

However, eligibility is not determined exclusively by income. Foreign investments, ownership interests in companies, certain types of income, and failure to comply with Mexican tax obligations can prevent taxpayers from entering or remaining in the regime.

This guide explains how RESICO works in 2026, including its tax rates, income limits, eligibility requirements, annual tax return exemptions, foreign income treatment, investment restrictions, and practical examples.

1. What Is RESICO in Mexico?

RESICO stands for Régimen Simplificado de Confianza, or Simplified Trust Tax Regime.

Introduced in January 2022, RESICO was designed to simplify income tax compliance and provide favorable tax treatment for eligible taxpayers.

Mexican tax legislation establishes two separate RESICO frameworks:

RESICO for individuals (Personas Físicas)

This regime is available to qualifying individuals conducting business activities, providing independent professional services, or earning rental income, subject to an annual income limit of MXN $3.5 million and other eligibility requirements.

Income tax rates range from 1% to 2.5%.

RESICO for legal entities (Personas Morales)

This regime applies to certain qualifying Mexican legal entities, generally with annual revenue not exceeding MXN $35 million and satisfying specific shareholder and eligibility requirements.

Unlike RESICO for individuals, qualifying legal entities calculate income tax under a different framework, generally applying the corporate income tax rate of 30% to the corresponding taxable base.

This article focuses on RESICO for individuals, particularly foreign residents and professionals receiving income from international clients.

2. Who Can Qualify for RESICO?

Article 113-E of Mexico’s Income Tax Law (Ley del Impuesto sobre la Renta, or LISR) establishes the principal requirements.

RESICO is generally available to qualifying individuals who conduct:

• Business and commercial activities.
• Independent professional services.
• Consulting and freelance work.
• Real estate rental activities.
• Agricultural, livestock, forestry, and fishing activities, subject to special provisions.

The taxpayer’s relevant annual income must generally remain within the MXN $3.5 million statutory limit.

Individuals beginning operations may also elect RESICO when their estimated revenue satisfies the applicable conditions.

However, meeting the income threshold does not automatically establish eligibility.

Certain investments, corporate ownership interests, income classifications, and other legal circumstances can prevent an individual from qualifying.

Can employees also use RESICO?

Yes, under certain conditions.

Employment income cannot itself be taxed under RESICO, but individuals receiving salaries may potentially apply RESICO to their separate qualifying business or professional activities.

For example, a person employed by a Mexican company who also provides independent consulting services may qualify for RESICO on the consulting income.

The taxpayer must comply with the applicable combined income limitations and the rules governing each category of income.

3. RESICO Income Tax Rates in Mexico for 2026

One of RESICO’s most significant advantages is its simplified income tax calculation.

Unlike Mexico’s general individual income tax regime, where progressive rates can reach 35%, RESICO applies substantially lower percentages to qualifying collected revenue.

Monthly RESICO Tax Rates

These rates are applied to qualifying revenue actually collected, excluding VAT.

The applicable percentage is generally applied to the entire qualifying monthly revenue amount, rather than using a progressive marginal tax calculation.

Practical Example: Freelancer Earning MXN $60,000 Monthly

Consider a freelance software developer who receives MXN $60,000 during a month.

The monthly income tax would be MXN $900, before considering any applicable withholding.

This example excludes VAT and assumes that the taxpayer meets all RESICO eligibility requirements.

The simplicity of this calculation makes RESICO particularly attractive to professionals with relatively low operating expenses.

4. RESICO vs. Mexico’s General Business Tax Regime

Before selecting RESICO, individuals should compare it with Mexico’s general business and professional activities regime.

Under the general regime, income tax is calculated based on taxable profit, considering authorized deductions and progressive tax rates.

Under RESICO, income tax is generally calculated on collected revenue without deducting operating expenses.

For independent consultants, freelancers, and other service providers with limited expenses, RESICO may produce substantial income tax savings.

However, businesses with significant operating costs should evaluate whether the general regime provides a more favorable result.

The lowest nominal tax rate is not necessarily the best tax outcome for every taxpayer.

5. Can Foreigners Qualify for RESICO in Mexico?

Yes. Foreign nationals can potentially qualify for RESICO if they are Mexican tax residents and meet the other statutory requirements.

Mexican citizenship is not required.

However, immigration status and tax residency are different legal concepts.

A foreign national holding temporary or permanent immigration residency does not automatically qualify as a Mexican tax resident.

Likewise, spending fewer than 183 days in Mexico does not necessarily prevent an individual from becoming a Mexican tax resident.

How Is Mexican Tax Residency Determined?

Article 9 of Mexico’s Federal Tax Code (Código Fiscal de la Federación, or CFF) establishes the principal domestic tax residency rules.

For individuals, relevant considerations include:

• Having a home in Mexico.
• The location of the individual’s center of vital interests, when applicable.
• The location and nature of income-generating activities.
• Other circumstances relevant under Mexican domestic law and applicable tax treaties.

Consequently, a foreign national who establishes a home and center of vital interests in Mexico may become a Mexican tax resident even while receiving all their professional income from foreign customers.

Mexican tax residents are generally subject to Mexican income tax on worldwide income, subject to applicable exemptions and treaty provisions.

Example: American Consultant Living in Mexico

An American citizen relocates to Guadalajara and provides consulting services to US companies.

The individual:

• Establishes Mexican tax residency.
• Earns MXN $1.8 million annually.
• Does not own shares in corporations.
• Does not receive income incompatible with RESICO.
• Complies with Mexican tax registration and invoicing obligations.

Subject to a complete eligibility assessment, the individual may qualify for RESICO.

However, US citizenship can create continuing US federal tax filing obligations, and the interaction between Mexican and US tax systems should be evaluated separately.

6. Can Freelancers Working for US or Foreign Companies Use RESICO?

Yes, potentially.

A common misconception is that RESICO applies only to individuals earning income from Mexican customers.

In reality, the customer’s country of residence does not automatically determine eligibility.

A Mexican tax resident may provide independent services to clients located in the United States, Canada, Europe, or other countries and potentially apply RESICO to the corresponding income.

Examples include:

• Software developers working remotely for US companies.
• Marketing consultants with international clients.
• Graphic designers providing services abroad.
• Independent IT consultants.
• Freelance writers and content creators.
• Business consultants working with foreign companies.

The relevant considerations include the legal classification of the income, the taxpayer’s tax residency, annual revenue, and compliance with the other RESICO requirements.

What About Wise, PayPal, Stripe, or Payoneer?

Receiving payments through international financial platforms does not automatically prevent a taxpayer from qualifying for RESICO.

However, income must be properly documented and reported.

Taxpayers should identify the date on which revenue was effectively collected, apply the relevant foreign exchange rules, and issue Mexican electronic invoices (CFDI) when required.

The use of an international bank account or payment platform does not eliminate Mexican tax obligations.

Special consideration is also necessary for income received through digital platforms that may be subject to specific Mexican tax provisions.

7. Does RESICO Include VAT?

No.

RESICO determines the applicable income tax treatment, but it does not automatically eliminate Value Added Tax (IVA) obligations.

Mexico’s standard VAT rate is generally 16%.

Depending on the nature of the transaction, certain activities may qualify for zero-rating or exemption.

Services Provided to Foreign Customers

Certain services provided to foreign customers may qualify for Mexico’s 0% VAT rate under the exportation-of-services provisions.

However, the fact that a customer is located abroad or pays in foreign currency does not automatically establish eligibility for zero-rated VAT.

The nature of the service, its use or exploitation abroad, and the requirements established by the Mexican VAT Law must be evaluated.

Practical Example

A software developer living in Mexico provides services to a US company.

For income tax purposes, the developer may qualify for RESICO.

For VAT purposes, a separate analysis is required to determine whether the services meet the conditions for zero-rating as an export.

Incorrectly applying the 0% VAT rate can create significant tax exposure.

Can RESICO Taxpayers Credit VAT on Expenses?

Potentially, yes.

Although business expenses are not deducted when calculating individual RESICO income tax, VAT creditability follows separate legal rules.

A qualifying taxpayer may be entitled to credit VAT paid on eligible expenses when the requirements of the VAT Law are satisfied.

8. RESICO and Foreign Investments: Stocks, ETFs, and Dividends

Foreign investments are among the most important issues for expatriates considering RESICO.

Many foreign residents maintain investment accounts in the United States, Europe, Canada, or other jurisdictions.

These accounts may contain:

• Shares in publicly traded companies.
• Exchange-traded funds (ETFs).
• Bonds and money market instruments.
• Investment funds.
• Retirement accounts.
• Other financial products.

While RESICO provides attractive tax rates, certain investment structures can create eligibility restrictions.

Foreign Corporate Shares

Article 113-E generally excludes individuals who are partners, shareholders, or members of legal entities, subject to specific exceptions.

Consequently, an individual who owns shares in a foreign corporation may face restrictions on RESICO eligibility.

The fact that the corporation is incorporated outside Mexico does not automatically resolve the issue.

What About ETFs?

ETFs require a more detailed legal analysis.

Not every ETF has the same structure.

Some are organized as investment companies, while others may operate through trusts or other legal arrangements.

For Mexican tax purposes, it is important to determine the actual legal nature of the instrument and the rights acquired by the investor.

Accumulating ETFs and Unrealized Gains

Some ETFs accumulate investment returns without distributing cash to investors.

An increase in market value does not ordinarily create realized income solely because the investment has appreciated.

However, this does not automatically establish RESICO eligibility.

Two separate questions must be evaluated:

1. Whether the investment produces income that must be recognized for Mexican tax purposes.
2. Whether ownership of the instrument creates a legal restriction on participating in RESICO.

An investment may not generate currently taxable income while still presenting an eligibility concern.

At TAX ID Mexico, we recommend a conservative approach when evaluating foreign investment portfolios.

Where the legal classification of an investment creates uncertainty, the potential tax benefits of RESICO should be weighed against the risk of losing eligibility.

What About Interest Income?

Certain interest income may coexist with RESICO under the applicable legal provisions.

However, interest must be distinguished from dividends, capital gains, and returns from other financial instruments.

The legal classification of the income is essential.

9. Who Cannot Use RESICO?

Even individuals earning less than MXN $3.5 million annually may be excluded from RESICO.

Under Article 113-E, important restrictions include individuals who:

• Are partners, shareholders, or members of legal entities, except where specific exceptions apply.
• Are related parties under the relevant legal provisions.
• Are foreign tax residents with a permanent establishment in Mexico.
• Receive income subject to preferential tax regimes under the applicable provisions.
• Receive certain income assimilated to employment under Article 94 of the Income Tax Law.

Other compliance-related restrictions may also apply.

For foreign residents, corporate ownership and international investment structures are particularly important.

Before choosing RESICO, taxpayers should review their complete financial situation rather than evaluating only their freelance or consulting revenue.

10. What Are the Tax Obligations Under RESICO in 2026?

RESICO simplifies income tax calculations but does not eliminate administrative obligations.

RFC Registration

Taxpayers must register with Mexico’s Tax Administration Service (SAT) and maintain the appropriate tax activities and obligations.

Electronic Invoicing (CFDI)

Taxpayers must issue electronic tax invoices for their activities in accordance with Mexican tax rules.

This obligation can also apply when providing services to foreign customers.

Electronic Signature (e.firma)

RESICO taxpayers must comply with the electronic signature requirements.

Under Rule 3.13.33 of the 2026 Miscellaneous Tax Resolution, individuals entering RESICO generally have until two months after submitting the corresponding RFC notice to obtain their e.firma.

Taxpayers should also maintain their electronic signature in valid condition.

The SAT password, commonly referred to as CIEC, should not be considered a permanent substitute for the e.firma requirement.

Monthly Income Tax Returns

RESICO taxpayers generally file monthly income tax returns by the 17th day of the following month, subject to applicable deadline extensions.

Income tax is calculated using qualifying revenue actually collected, excluding VAT.

Withholding by Mexican Companies

When a RESICO individual provides qualifying services to a Mexican legal entity, Article 113-J generally requires the company to withhold 1.25% income tax on the payment, excluding VAT.

This withholding can be credited against the individual’s corresponding RESICO income tax.

The withholding rules may differ for certain activities and transactions.

Annual Income Tax Return: Important 2026 Exemption

One of RESICO’s significant administrative advantages in 2026 is the exemption from filing an annual income tax return for qualifying RESICO income.

Under Rule 3.13.7 of the 2026 Miscellaneous Tax Resolution, monthly RESICO income tax payments are treated as final payments.

Consequently, qualifying taxpayers are relieved from filing an annual income tax return for income covered by RESICO.

This relief applies to the RESICO income itself.

Individuals who also receive salaries or interest income must separately determine whether those additional income categories create an annual tax filing obligation.

Similarly, taxpayers who leave RESICO during the year may have additional filing requirements under the applicable transition rules.

RESICO Income Tax Refunds

Taxpayers with qualifying RESICO income tax balances in their favor may request refunds under Rule 3.13.34.

The rule allows eligible taxpayers to request refunds of balances reported in monthly final returns or, subject to its conditions, request the accumulated annual amount through the SAT refund procedure.

A separate annual RESICO return is not necessarily required to request these refunds.

VAT and Other Compliance Requirements

The annual RESICO income tax return exemption does not eliminate monthly VAT obligations.

Taxpayers must also maintain appropriate documentation and comply with applicable tax mailbox requirements.

The SAT has established specific transitional relief for tax mailbox activation, so the applicable deadline should be checked for the taxpayer’s circumstances.

11. What Happens If You Exceed the MXN $3.5 Million Income Limit?

For fiscal year 2026, the annual RESICO income threshold for individuals remains MXN $3.5 million.

An individual who exceeds this threshold generally loses eligibility and must transition to the corresponding tax regime beginning in the month following the event that causes the loss of eligibility.

This may result in substantially different income tax calculations and filing obligations.

Practical Example

A consultant initially expects annual revenue of MXN $3 million.

However, additional contracts increase collected revenue above MXN $3.5 million during the year.

The taxpayer must evaluate the mandatory transition out of RESICO and determine the appropriate income tax treatment under the applicable provisions.

The transition rules can affect the treatment of payments previously made under RESICO.

What About a Proposed Increase to MXN $5 Million?

Proposals have been discussed to increase the income threshold to MXN $5 million for 2027.

However, proposed legislation should not be confused with enacted law.

For 2026, taxpayers should continue applying the MXN $3.5 million statutory threshold.

Any future increase would require the corresponding legislative approval and effective date.

12. Can You Return to RESICO After Losing Eligibility?

Possibly, depending on the reason for leaving the regime.

Exceeding the income threshold is not necessarily equivalent to losing eligibility because of noncompliance.

The applicable legislation and administrative rules may allow reentry under certain circumstances.

However, taxpayers who lose eligibility because of failure to meet specific tax obligations may face additional restrictions.

Before attempting to return to RESICO, individuals should review their filing history, the reason for their departure, and the requirements applicable to the intended year of reentry.

13. Three Practical RESICO Examples

Case 1: US Software Developer Living in Mexico

A US citizen lives in Guadalajara and provides software development services to American companies.

Annual revenue: MXN $1.5 million.

The individual has established Mexican tax residency, does not own corporate shares, and receives no incompatible investment income.

Tax analysis: RESICO may be available if all statutory requirements are satisfied.

The foreign location of the customers does not automatically prevent eligibility.

VAT treatment must be analyzed separately.

Case 2: Canadian Consultant With Foreign Investments

A Canadian citizen becomes a Mexican tax resident and receives MXN $2 million annually from consulting activities.

The individual also owns shares in several foreign corporations through an international brokerage account.

Tax analysis: Although the consulting income is below the RESICO threshold, corporate share ownership creates a significant eligibility concern.

The investment portfolio must be reviewed before selecting RESICO.

Case 3: Freelancer Exceeding the Income Limit

An independent marketing professional initially expects annual revenue of MXN $2.8 million.

Several additional contracts increase revenue beyond MXN $3.5 million.

Tax analysis: The individual must evaluate the mandatory transition to the appropriate tax regime and comply with the corresponding tax calculations and reporting obligations.

Failing to identify the transition promptly can result in incorrect tax filings.

14. Frequently Asked Questions About RESICO in Mexico

Is RESICO available to foreigners?

Yes. Foreign nationals who qualify as Mexican tax residents may potentially use RESICO if they meet the applicable requirements.

Do I need Mexican citizenship to qualify?

No. Mexican citizenship is not required. Tax residency and statutory eligibility are the relevant considerations.

Can I use RESICO if all my clients are in the United States?

Yes, potentially. The foreign location of customers does not automatically prevent eligibility.

Can I receive payments in US dollars?

Yes. Foreign-currency income must be properly documented and converted for Mexican tax purposes.

Is RESICO income tax really only 1% to 2.5%?

Yes, for qualifying individual RESICO income. VAT and other applicable tax obligations must be considered separately.

Do RESICO taxpayers need to file an annual income tax return in 2026?

Generally, qualifying taxpayers are exempt from filing an annual return for their RESICO income under Rule 3.13.7 of the 2026 Miscellaneous Tax Resolution.

What if I receive RESICO income and employment income?

You must separately evaluate the annual filing requirements applicable to your employment income.

Receiving both types of income does not automatically eliminate the annual filing relief for RESICO income.

Can I request a RESICO tax refund without filing an annual return?

Yes, where the applicable requirements are satisfied. Rule 3.13.34 establishes a procedure for requesting qualifying RESICO income tax refunds.

Is an e.firma mandatory for RESICO in 2026?

Yes. Taxpayers must comply with the electronic signature requirement, including the applicable two-month period for individuals entering the regime under Rule 3.13.33.

Can I own a US LLC and qualify for RESICO?

Ownership of an LLC may create significant eligibility concerns. The legal structure, ownership rights, and applicable Mexican tax provisions must be evaluated.

Can I own ETFs while using RESICO?

It depends on the legal characteristics of the instruments. Certain structures may create corporate ownership or income classification issues.

Can I receive interest income under RESICO?

Certain interest income may coexist with RESICO under the applicable statutory conditions.

Can I receive dividends under RESICO?

Dividend income and the underlying ownership of corporate shares require careful analysis. In many cases, the share ownership itself may create a RESICO eligibility restriction.

Can I use RESICO while working through Upwork or Fiverr?

Potentially. The contractual relationship, classification of the income, invoicing obligations, and applicable digital platform provisions must be examined.

Do I need Mexican invoices if my clients are foreign?

Generally, yes. Mexican taxpayers must comply with applicable CFDI invoicing requirements, including for foreign-customer transactions.

Is RESICO the same as a digital nomad visa?

No. RESICO is an income tax regime, not an immigration category. Immigration authorization and tax residency are separate legal concepts.

Is the RESICO income limit MXN $5 million in 2026?

No. The applicable statutory threshold for 2026 remains MXN $3.5 million. Proposed changes for future years should not be treated as effective legislation until formally enacted.

15. Is RESICO the Best Tax Regime for Foreigners Living in Mexico?

RESICO can provide substantial income tax savings for qualifying individuals, particularly those providing professional services with limited operating expenses.

However, the decision should never be based exclusively on the attractive tax rates.

Before selecting RESICO, foreign residents should evaluate:

• Their Mexican tax residency status.
• Their worldwide income sources.
• Their ownership interests in foreign companies.
• Their investment portfolios.
• Their projected annual revenue.
• Their VAT obligations.
• Their foreign tax reporting requirements.
• Their eligibility under Mexican tax legislation.

A regime that initially appears beneficial can create significant tax exposure if the taxpayer does not satisfy the legal requirements.

RESICO is not simply a low-tax option. It is a preferential tax regime with specific eligibility conditions that must be respected.

La entrada RESICO in Mexico (2026): Complete Tax Guide for Foreigners, Freelancers, and Independent Professionals se publicó primero en TAX ID.

A primera vista, los cambios parecen favorables. Sin embargo, como ocurre frecuentemente en materia fiscal, una simplificación administrativa no necesariamente representa un ahorro de impuestos para todos los contribuyentes.

Por ello, resulta importante analizar qué modificaciones se están proponiendo, cuáles serían sus efectos y, sobre todo, en qué casos podrían representar una ventaja.

¿En qué etapa se encuentra la reforma?

Al 21 de octubre de 2026, la reforma a la Ley del Impuesto sobre la Renta ya fue aprobada por la Cámara de Diputados y se encuentra en el Senado de la República, donde continúa su proceso legislativo.

El proyecto contempla modificaciones a los artículos 113-E, 113-F y 113-H de la Ley del ISR, relacionados con el Régimen Simplificado de Confianza de personas físicas.

Los cambios todavía no se encuentran vigentes. Para su aplicación será necesario que concluya el procedimiento legislativo correspondiente y se publique el decreto en el Diario Oficial de la Federación.

1. Incremento del límite de ingresos de 3.5 a 5 millones de pesos

Actualmente, las personas físicas que desean tributar en RESICO deben cumplir, entre otros requisitos, con un límite de ingresos anuales de $3,500,000.

La propuesta contempla incrementar ese límite a $5,000,000, lo que permitiría que un mayor número de contribuyentes acceda al régimen o permanezca en él.

Este cambio resulta especialmente relevante para profesionistas independientes, comerciantes, arrendadores y prestadores de servicios que han incrementado sus ingresos y que, bajo las reglas actuales, se ven obligados a abandonar RESICO.

Por ejemplo, una persona física que obtiene ingresos anuales por $4,500,000 actualmente no puede permanecer en el régimen por superar el límite permitido. Con la reforma, podría continuar tributando en RESICO, siempre que cumpla los demás requisitos.

Es importante señalar que el incremento del límite no elimina las restricciones del artículo 113-E, particularmente aquellas relacionadas con la participación en sociedades, determinados tipos de ingresos y otras condiciones que impiden tributar en este régimen.

Asimismo, la propuesta mantiene una tasa máxima de ISR del 2.5% para los contribuyentes que se ubiquen en el nuevo límite de ingresos.

2. La posibilidad de regresar a RESICO

Uno de los cambios más interesantes es la propuesta de permitir que determinadas personas físicas puedan regresar al régimen después de haberlo abandonado.

Actualmente, la salida de RESICO puede generar consecuencias importantes, particularmente cuando ocurre por incumplimiento de obligaciones fiscales.

La iniciativa contempla flexibilizar las condiciones de reingreso, permitiendo que los contribuyentes puedan regresar a partir del ejercicio fiscal siguiente cuando se encuentren al corriente en sus obligaciones, cumplan los requisitos legales y no excedan el nuevo límite de ingresos.

Esto podría beneficiar a contribuyentes que anteriormente perdieron la posibilidad de tributar en RESICO, pero que posteriormente regularizaron su situación fiscal.

Sin embargo, hay que distinguir entre diferentes situaciones:

• Contribuyentes que abandonaron RESICO por superar el límite de ingresos.
• Contribuyentes que fueron excluidos por incumplimientos fiscales.
• Contribuyentes que dejaron de cumplir otros requisitos legales, como determinadas restricciones por su participación en sociedades.

No necesariamente todos los casos tendrán el mismo tratamiento.

Además, la propuesta contempla que, cuando un contribuyente exceda el nuevo límite de $5,000,000, deba abandonar RESICO a partir del mes siguiente, conservando el carácter definitivo de los pagos realizados bajo dicho régimen, conforme a la mecánica propuesta.

Este último punto resulta relevante porque podría reducir las complicaciones asociadas con la transición entre regímenes fiscales.

3. Una nueva opción para pagar IVA al 7%

Probablemente, la modificación que más atención ha generado es la propuesta de establecer una mecánica simplificada para determinar el IVA.

Actualmente, los contribuyentes de RESICO determinan este impuesto mediante el procedimiento general: calculan el IVA correspondiente a sus actividades y disminuyen el IVA acreditable que cumpla los requisitos legales.

La propuesta contempla una alternativa para determinados contribuyentes, consistente en calcular el impuesto aplicando una tasa efectiva del 7% sobre el valor de sus actividades gravadas efectivamente cobradas, sin acreditar el IVA trasladado por sus proveedores ni el pagado en importaciones.

Es importante aclarar que esto no significa que la tasa general del IVA disminuya del 16% al 7%.

Las operaciones continuarían sujetas a las tasas que legalmente correspondan. Lo que cambiaría sería la mecánica para determinar el impuesto a pagar al SAT cuando se ejerza esta opción.

De acuerdo con los análisis publicados sobre la iniciativa, la elección de esta alternativa tendría que mantenerse durante el ejercicio fiscal correspondiente.

Caso práctico 1. Un profesionista independiente

Supongamos que un consultor obtiene ingresos mensuales de $100,000, antes de IVA, y tiene gastos que generan $2,000 de IVA acreditable.

AHORRO MENSUAL HIPOTÉTICO

$7,000 MXN

En este escenario, la opción simplificada podría representar un ahorro importante, debido a que el contribuyente tiene pocos gastos que generan IVA acreditable.

Esta situación puede presentarse en actividades profesionales y de servicios donde una parte importante de los costos corresponde a nómina, honorarios asimilados u otras erogaciones que no generan IVA acreditable.

Caso práctico 2. Un comerciante con inventarios

Ahora consideremos a un comerciante con los mismos ingresos mensuales de $100,000, pero que adquiere mercancías y realiza gastos que generan $12,000 de IVA acreditable.

MAYOR IMPUESTO MENSUAL CON LA OPCIÓN SIMPLIFICADA

$3,000 MXN

En este caso, el esquema simplificado sería menos conveniente.

El contribuyente estaría renunciando a un acreditamiento de IVA que le permite determinar un impuesto menor mediante el procedimiento tradicional.

Los ejemplos anteriores son ilustrativos, consideran operaciones gravadas al 16% y suponen que se cumplen los requisitos de acreditamiento. No incorporan retenciones, saldos a favor ni otras particularidades que pueden modificar el resultado.

¿En qué punto deja de convenir el IVA del 7%?

En una operación totalmente gravada al 16%, el punto de equilibrio se presenta cuando el IVA acreditable equivale al 9% de los ingresos gravados.

Simulador comparativo de IVAIngresos mensuales antes de IVA

$100,000IVA acreditable mensual

$5,000

IVA tradicional

$11,000

IVA opcional 7%

$7,000

Ahorro potencial: $4,000Simulación ilustrativa de pagos de IVA. No considera retenciones, actividades a tasa 0%, exentas ni saldos a favor. La opción está sujeta a la aprobación definitiva de la reforma.

Por ello, la elección no debería realizarse únicamente por la facilidad administrativa. Será necesario evaluar la estructura de costos, las inversiones previstas y el IVA acreditable que genera cada actividad.

4. Incremento de la exención para actividades del sector primario

La propuesta también contempla incrementar de $900,000 a $1,000,000 el monto de ingresos exentos de ISR para personas físicas que realizan exclusivamente actividades agrícolas, ganaderas, silvícolas o pesqueras, bajo las condiciones previstas en la legislación.

Este ajuste busca ampliar el beneficio para pequeños productores del sector primario.

Sin embargo, debe recordarse que la exención no es aplicable de manera general a cualquier persona física inscrita en RESICO, sino únicamente a quienes cumplen las condiciones específicas de este tratamiento.

5. Otras facilidades administrativas propuestas

Además de los cambios anteriores, durante la presentación del paquete fiscal se anunciaron medidas orientadas a simplificar el cumplimiento de obligaciones.

Entre ellas se encuentran la posibilidad de realizar determinados pagos de ISR de manera trimestral, facilidades para regularizar obligaciones pendientes y una declaración simplificada que integre información de ISR e IVA.

No obstante, es importante distinguir entre las modificaciones expresamente incorporadas a la iniciativa legal y aquellas que podrían requerir reglas administrativas posteriores.

Por ello, el alcance definitivo de estas facilidades deberá revisarse una vez concluido el procedimiento legislativo y publicadas las disposiciones correspondientes.

6. Caso práctico 3. Una persona física que supera el límite actual de RESICO

Supongamos que una persona física dedicada a prestar servicios profesionales obtiene los siguientes ingresos:

Durante 2026, al superar el límite de $3,500,000, el contribuyente tendría que abandonar RESICO conforme a las disposiciones vigentes y tributar en el régimen que le corresponda.

Sin embargo, si se aprueba la reforma, podría analizarse su regreso a RESICO durante 2027, siempre que cumpla las condiciones de reingreso y los demás requisitos legales.

La diferencia económica puede ser considerable.

En RESICO, el ISR se determina aplicando tasas reducidas sobre los ingresos efectivamente cobrados, sin deducciones. En cambio, en el régimen de actividades empresariales y profesionales, el impuesto se determina considerando ingresos, deducciones autorizadas y tarifas progresivas.

Por lo tanto, aunque RESICO puede resultar atractivo por sus tasas reducidas, no debe olvidarse que la comparación correcta depende de la rentabilidad del contribuyente y de su estructura de gastos.

7. Preguntas frecuentes sobre la reforma RESICO 2027

¿Ya puedo facturar cinco millones de pesos y continuar en RESICO durante 2026?

No. El límite vigente para 2026 continúa siendo de $3,500,000. La propuesta de incremento a cinco millones todavía no tiene efectos legales.

¿La tasa máxima del ISR también aumentará?

No se contempla un incremento. La propuesta mantiene la tasa máxima del 2.5% y amplía su aplicación al nuevo límite de ingresos.

¿Todos los contribuyentes podrán regresar a RESICO?

No necesariamente. El reingreso estará sujeto a las condiciones legales correspondientes. La reforma no elimina automáticamente las restricciones relacionadas con socios, accionistas y otras causas de exclusión.

¿El IVA del 7% significa que debo facturar a esa tasa?

No. La propuesta consiste en una mecánica alternativa de determinación del impuesto, no en sustituir la tasa general del IVA aplicable a las operaciones.

¿El IVA del 7% será obligatorio?

La propuesta lo presenta como una opción para los contribuyentes que cumplan los requisitos correspondientes, por lo que podría mantenerse el esquema tradicional.

¿Puedo elegir el IVA del 7% únicamente en los meses que me convenga?

Los análisis de la iniciativa señalan que la opción deberá mantenerse durante todo el ejercicio fiscal. Por lo tanto, será necesario evaluar su conveniencia de manera anual y no solamente mensual.

¿Qué sucede con quienes prestan servicios a clientes extranjeros?

Deberá analizarse el tratamiento de IVA de cada operación. Si los servicios cumplen los requisitos para aplicar la tasa del 0% por exportación, la conveniencia de una opción simplificada puede ser muy distinta a la de un contribuyente que realiza operaciones gravadas al 16%.

No debe asumirse que el 7% sustituirá automáticamente el tratamiento de las exportaciones o que resultará aplicable a todas las actividades.

Conclusiones

La propuesta de reforma al RESICO para 2027 representa una modificación importante en el tratamiento fiscal de las personas físicas.

El incremento del límite de ingresos de 3.5 a 5 millones de pesos permitiría que un mayor número de contribuyentes acceda al régimen, mientras que las nuevas condiciones de reingreso podrían ofrecer una alternativa para quienes anteriormente tuvieron que abandonarlo.

Sin embargo, considero que el cambio que requiere mayor análisis es la opción de determinar el IVA mediante una tasa efectiva del 7%.

Para contribuyentes que prestan servicios profesionales y tienen pocos gastos sujetos a IVA, esta alternativa podría representar un ahorro importante. Por el contrario, para comerciantes y negocios que realizan inversiones o adquisiciones significativas, renunciar al acreditamiento podría incrementar su carga fiscal.

También será importante analizar las condiciones de permanencia, reingreso y transición entre regímenes, particularmente para quienes superaron el límite de ingresos durante 2026.

La simplificación fiscal no debe confundirse con una reducción automática de impuestos. Cada contribuyente deberá analizar sus ingresos, gastos, inversiones y obligaciones antes de decidir si las nuevas opciones realmente le resultan convenientes.

Finalmente, debe recordarse que, al 21 de octubre de 2026, las modificaciones continúan sujetas al procedimiento legislativo. Será necesario revisar el texto definitivo de la reforma y las reglas administrativas que, en su caso, emita el SAT.

La entrada RESICO 2027: más ingresos, menos impuestos y una nueva forma de pagar IVA. ¿Realmente conviene? se publicó primero en TAX ID.

There is a widespread belief among expatriates, entrepreneurs, investors, and digital nomads: if you spend fewer than 183 days per year in Mexico, you are not a Mexican tax resident and therefore do not have to pay taxes in the country.

This assumption frequently appears in expat communities, online forums, social media discussions, and even professional advice.

However, Mexican tax law does not establish a general 183-day rule for determining tax residency.

An individual may spend fewer than six months in Mexico and still qualify as a Mexican tax resident. Similarly, a company incorporated in the United States, Canada, or another country could be considered a Mexican tax resident if its effective management and key business decisions are carried out from Mexico.

The fundamental question is not simply how many days you spend in Mexico, but whether your personal, economic, and business circumstances meet the legal requirements for Mexican tax residency.

To understand these rules, we will examine Article 9 of the Mexican Federal Tax Code (Código Fiscal de la Federación, or CFF) and three practical examples involving individuals and foreign companies.

1. What Determines Tax Residency in Mexico?

Article 9 of the Mexican Federal Tax Code establishes different criteria for individuals and legal entities.

Individuals: Permanent Home and Center of Vital Interests

For individuals, the first consideration is whether they have established a home in Mexico.

When an individual also maintains a home in another country, Mexican legislation provides that they will be considered a Mexican tax resident if their center of vital interests is located in Mexico.

Under Article 9, an individual’s center of vital interests is considered to be in Mexico when either of the following conditions is met:

• More than 50% of their total income during the calendar year is derived from Mexican sources.
• The principal center of their professional activities is located in Mexico.

These rules are particularly relevant for expatriates, remote workers, international consultants, and individuals who divide their time between different countries.

For example, someone may maintain a home in Mexico, work exclusively for American clients, receive payments into a US bank account, and still qualify as a Mexican tax resident.

It is also important to distinguish between owning real estate and establishing a home. Simply owning a property in Mexico does not necessarily establish tax residency if the property does not constitute the individual’s actual home.

Companies: Principal Place of Management and Effective Place of Management

For legal entities, the analysis is different.

Article 9, Section II, of the Mexican Federal Tax Code establishes that legal entities are considered Mexican tax residents when their principal place of business management or effective place of management is located in Mexico.

Article 6 of the Regulations to the Federal Tax Code further develops this concept by focusing on where the individuals responsible for controlling, directing, operating, or administering the company make or execute relevant decisions.

Consequently, incorporating a company abroad does not automatically guarantee that the company will be considered a foreign tax resident for Mexican tax purposes.

A company’s tax residency is not determined exclusively by where it was incorporated, but also by where it is effectively managed.

2. Practical Case: An American Freelancer Living in Mexico

Consider the following situation.

Michael is a US citizen who works as an independent software developer.

He spends approximately 150 days per year in Mexico and travels between the United States and other countries for the remainder of the year.

Michael rents a house in Mérida, where he keeps his personal belongings and regularly performs his professional activities. He does not maintain another home available to him in the United States.

All his clients are American and European companies. His consulting fees are deposited into a US bank account, and he never receives payments directly into a Mexican bank.

Michael believes he is not a Mexican tax resident because he spends fewer than 183 days in the country and all his income comes from foreign clients.

Is Michael Correct?

Not necessarily.

In this example, Michael has established his home in Mexico.

If this circumstance is established, he may meet the tax residency requirements under Article 9 of the Federal Tax Code, even though he spends only 150 days per year in Mexico.

The fact that his income comes from foreign clients or is deposited into an American bank account does not, by itself, change his tax residency.

If Michael qualifies as a Mexican tax resident, Article 1 of the Mexican Income Tax Law generally requires him to report his worldwide income.

Depending on their nature and applicable tax treatment, this may include:

• Consulting fees received from foreign clients.
• Employment income paid by foreign companies.
• Interest and investment income.
• Dividends and capital gains.
• Other income generated outside Mexico.

If Michael is also considered a US tax resident, the Mexico–United States tax treaty must be reviewed to determine the applicable treatment, including any relevant dual-residency provisions and mechanisms to prevent or mitigate double taxation.

Special attention must also be given to the treaty’s saving clause and the rules applicable to US citizens.

Case conclusion: Spending fewer than 183 days in Mexico does not prevent an individual from becoming a Mexican tax resident when the requirements of Article 9 are met.

3. Practical Case: A Mexican Entrepreneur Who Moves Abroad

Now consider Roberto, a Mexican entrepreneur who decides to relocate to Spain.

Roberto spends approximately 250 days per year in Spain, where he has established a permanent home and carries out some of his personal activities.

However, he also maintains a home available to him in Mexico and continues to manage a significant portion of his business interests there.

Roberto owns shares in several Mexican companies, actively participates in their management, and receives most of his income from Mexican sources.

He believes that spending more than 183 days in Spain automatically means he is no longer a Mexican tax resident.

Is Spending More Than Six Months Abroad Enough?

No.

When an individual maintains a home in Mexico and another country, Mexican legislation requires an analysis of their center of vital interests.

In Roberto’s case, if more than 50% of his total income is derived from Mexican sources, one of the specific conditions established under Article 9 of the Federal Tax Code would be met.

It is also necessary to examine where the principal center of his professional activities is located.

Therefore, even though Roberto spends most of the year in Spain, he could continue to qualify as a Mexican tax resident under Mexican domestic law.

This does not necessarily mean he must pay tax twice on the same income.

If Spain also considers him a tax resident, the Mexico–Spain tax treaty must be analyzed, particularly its provisions for resolving dual-residency conflicts.

Additionally, when an individual effectively changes tax residency, the applicable notification requirements before the Mexican Tax Administration Service (Servicio de Administración Tributaria, or SAT) must be reviewed.

Article 9 of the Federal Tax Code establishes specific requirements and consequences concerning the notification of a change in tax residency.

Failing to comply with these requirements may create significant tax risks, even when the individual has physically relocated abroad.

Case conclusion: Moving abroad does not automatically terminate Mexican tax residency. The analysis must consider the individual’s homes, center of vital interests, professional activities, applicable tax treaties, and formal compliance requirements.

4. Practical Case: A US LLC Managed from Mexico

This third example is particularly relevant for entrepreneurs, consultants, and professionals who establish companies in the United States while living in Mexico.

Suppose Daniel lives in Guadalajara and owns an LLC incorporated in Delaware.

The company provides technology consulting services to American and European clients.

It maintains a US bank account, receives payments through international platforms, and complies with its applicable US tax filing requirements.

However, Daniel performs nearly all the company’s important business activities from Mexico.

He:

• Negotiates and signs contracts with clients.
• Establishes service prices.
• Authorizes payments and bank transfers.
• Hires contractors and service providers.
• Makes financial and commercial decisions.
• Supervises the company’s daily operations.

Daniel believes that because his LLC was incorporated in Delaware, it is automatically a foreign company whose business income has no Mexican corporate tax consequences.

Can a US Company Be Considered a Mexican Tax Resident?

Yes, depending on the circumstances.

Article 9, Section II, of the Federal Tax Code does not limit corporate tax residency to the country of incorporation.

Instead, it considers where the company’s principal place of business management or effective place of management is located.

If the company’s relevant management and control decisions are made or executed from Mexico, the Mexican tax authorities could determine that its principal management or effective place of management is located in Mexican territory.

Depending on the entity’s legal structure and tax classification, this could create Mexican corporate tax obligations.

The analysis is particularly important for LLCs because their US tax classification may differ from their treatment under Mexican tax legislation.

For example, an LLC may be treated as a disregarded entity or partnership for certain US federal tax purposes without necessarily receiving equivalent treatment in Mexico.

Tax Residency vs. Permanent Establishment

Another important distinction involves the concept of a permanent establishment.

A foreign company may face Mexican tax consequences because it is considered a Mexican tax resident, because it maintains a permanent establishment in Mexico, or potentially under both sets of rules, depending on the facts.

These concepts should not be confused.

Tax residency generally creates a broader tax connection with a country, potentially resulting in taxation of worldwide income.

A permanent establishment, on the other hand, generally allows a country to tax certain business profits attributable to activities conducted within its territory, subject to domestic legislation and applicable tax treaties.

Case conclusion: Incorporating an LLC or corporation in the United States does not automatically place its operations outside the scope of Mexican tax law. The company’s actual management structure, decision-making processes, and tax classification must be carefully evaluated.

5. Where Does the Famous 183-Day Rule Come From?

The 183-day rule is not entirely fictional.

It appears in various countries’ domestic tax laws and in certain provisions of international tax treaties.

However, its application depends on the specific legal context.

For example, many double taxation treaties include a 183-day threshold in provisions dealing with employment income.

Under certain conditions, these provisions may affect whether employment remuneration can be taxed in the country where the work is performed.

Other countries also use physical presence tests when determining tax residency under their domestic legislation.

The mistake is assuming that these rules automatically apply to Mexican tax residency.

Article 9 of the Mexican Federal Tax Code does not establish a general rule under which spending fewer than 183 days in Mexico prevents an individual from becoming a Mexican tax resident.

Therefore, before relying on any day-counting rule, it is essential to identify the relevant domestic legislation, applicable tax treaty, and specific legal circumstances.

6. Frequently Asked Questions About Mexican Tax Residency

If I Spend Fewer Than 183 Days in Mexico, Do I Have to Pay Mexican Taxes?

It depends on your circumstances.

Spending fewer than 183 days in Mexico does not automatically exclude Mexican tax residency.

If you have established a home in Mexico or meet other applicable residency criteria, you may qualify as a Mexican tax resident.

Even if you are not a Mexican tax resident, you may still have Mexican tax obligations on certain income derived from Mexican sources.

Does Having Mexican Permanent Residency for Immigration Purposes Make Me a Tax Resident?

Not necessarily.

Immigration residency and tax residency are different legal concepts.

An individual may hold a Mexican permanent resident card without that document, by itself, establishing Mexican tax residency.

Tax residency must be determined under the applicable provisions of Article 9 of the Federal Tax Code.

If I Work Remotely for a US Company from Mexico, Do I Have to Pay Mexican Income Tax?

If you are a Mexican tax resident, you are generally required to consider your worldwide income, including employment income or professional fees received from foreign companies.

If you are not a Mexican tax resident, the analysis must consider where the services are performed, the source of income, and the applicable legal provisions.

Tax treaties and foreign tax credit rules may also be relevant.

If My Income Is Deposited into a Foreign Bank Account, Is It Exempt from Mexican Taxes?

No.

The location of your bank account does not, by itself, determine your tax residency or whether your income is taxable in Mexico.

Mexican tax residents may have reporting and tax obligations concerning income received in the United States, Canada, Europe, or other countries.

Can I Be a Tax Resident of Both Mexico and the United States?

Yes.

Both countries may consider the same individual a tax resident under their respective domestic laws.

When dual residency occurs, the applicable tax treaty must be reviewed.

For US citizens, additional treaty provisions and citizenship-based US taxation rules may affect the analysis.

Can a US LLC Be Considered a Mexican Tax Resident?

Potentially, yes.

If a foreign entity establishes its principal place of management or effective place of management in Mexico, it may meet the criteria established under Article 9, Section II, of the Federal Tax Code.

The conclusion requires reviewing the entity’s legal nature, tax classification, management structure, and actual decision-making processes.

What Is the Difference Between Tax Residency and a Permanent Establishment?

Tax residency establishes a general tax connection between an individual or legal entity and a country.

A permanent establishment generally allows a country to tax business profits attributable to certain activities conducted within its territory.

A foreign company may have a permanent establishment in Mexico without necessarily becoming a Mexican tax resident.

How Can I Prove That I Am No Longer a Mexican Tax Resident?

There is no single document that replaces a proper legal analysis.

Depending on the circumstances, relevant evidence may include:

• Foreign tax residency certificates.
• Housing agreements and supporting documentation.
• Employment and professional activity records.
• Income and business information.
• Evidence of the actual relocation of personal and economic interests.
• Documentation supporting compliance with Mexican tax residency change procedures.

The applicable notification requirements before the SAT must also be reviewed.

What Happens If I Fail to Notify the SAT of My Change in Tax Residency?

Article 9 of the Federal Tax Code establishes specific consequences for failing to submit the required notification.

Under the relevant provisions, failure to comply may prevent an individual from losing Mexican tax resident status for purposes of that article.

Therefore, physically relocating abroad without addressing the applicable formal requirements may create significant tax exposure.

Does Owning a House in Mexico Automatically Make Me a Tax Resident?

Not necessarily.

Owning real estate and establishing a home are different circumstances.

When an individual maintains homes in Mexico and another country, the center of vital interests must also be analyzed under Mexican domestic law.

The particular facts are essential.

7. Conclusion: Tax Residency Is Not Simply About Counting Days

Tax residency is one of the most important and frequently misunderstood aspects of international taxation.

The belief that spending fewer than 183 days in Mexico is enough to avoid Mexican tax obligations can lead to costly mistakes.

An individual who lives part of the year in Mexico, a Mexican entrepreneur relocating abroad, or a US company managed from Mexican territory may face tax consequences that cannot be identified simply by counting days.

At TAX ID Mexico, we believe a proper tax residency analysis should begin with the actual circumstances of the taxpayer.

Where is the individual’s home located? Where are their professional activities performed? What is the source of their income? Where are the company’s management and control decisions made?

Once these facts have been established, the relevant Mexican legislation, international tax treaties, and formal compliance obligations must be reviewed.

Tax residency is not something a taxpayer can freely choose or change simply by crossing a border. It is a legal consequence of their actual personal, economic, and business circumstances.

Before relocating to Mexico, moving abroad, establishing a foreign company, or beginning to work remotely for international clients, it is advisable to evaluate the potential tax implications.

La entrada The 183-Day Myth: When Are You Really a Tax Resident in Mexico? se publicó primero en TAX ID.

One of the first questions foreign companies ask is whether they need to establish a Mexican subsidiary. In many cases, the answer is no.

Mexican tax regulations allow certain foreign digital service providers to register directly with the Mexican Tax Administration Service (SAT) without creating a Mexican legal entity or having a permanent establishment.

However, this registration process is highly specialized and requires strict compliance with the documentation established by the Mexican Tax Miscellaneous Resolution.

Does every SaaS company need to register?

Not necessarily.

Although many SaaS businesses operate entirely online, each business model should be analyzed individually.

The Mexican VAT Law regulates specific digital services provided by foreign residents to customers located in Mexico. Whether your software falls within those provisions depends on the characteristics of the services provided rather than simply calling the business «SaaS.»

For this reason, a legal and tax analysis should always be performed before initiating any registration process.

Registration under Procedure 1/PLT

Foreign companies providing digital services without a permanent establishment in Mexico may be required to register under Procedure 1/PLT contained in Annex 2 of the Mexican Tax Miscellaneous Resolution.

According to this procedure, SAT requires the following documentation:

1. Certificate of Incorporation or equivalent corporate formation document, duly apostilled or legalized, showing that the company’s corporate purpose relates to providing digital platform services.
2. Official Spanish translation prepared by an authorized translator when corporate documents are executed in another language.
3. Foreign Tax Identification Number issued by the country of residence, whenever required under local law.
4. Proof of address in Mexico for notification purposes.
5. Power of Attorney or legal representation document. If executed abroad, it must be apostilled or legalized, formalized before a Mexican notary public and, when applicable, translated into Spanish by an authorized translator.
6. Valid government-issued identification of the legal representative.
7. Appointment of a legal representative in Mexico and designation of a Mexican address for tax notifications.
8. Official Form 1/PLT.

Additionally, the legal representative must already be registered with the Mexican Tax Administration Service (SAT).

Obtaining the Mexican Electronic Signature (e.firma)

After the RFC registration has been completed, the company must obtain its Mexican electronic signature (e.firma).

Procedure 2/PLT requires:

• USB drive containing the .req file generated using SAT’s Certifica software.
• Email address.
• Official FE Application Form.
• The same documentation submitted under Procedure 1/PLT.

Practical considerations

One of the most challenging aspects of the registration process is complying with the Mexican proof of address requirements.

Foreign companies should carefully review Annex 2 of the Mexican Tax Miscellaneous Resolution to determine which documents are accepted by SAT before preparing their application.

Because SAT generally follows the documentation requirements very strictly, submitting an incomplete or inconsistent file may delay the registration process.

Final thoughts

Mexico offers a specific registration process for foreign companies providing digital services without requiring them to incorporate a Mexican subsidiary.

Nevertheless, each SaaS business should first determine whether its services fall within the Mexican digital services regime before beginning the registration process.

Preparing the documentation in accordance with Procedures 1/PLT and 2/PLT from the outset can significantly reduce delays and facilitate obtaining both the Mexican Tax ID (RFC) and the electronic signature (e.firma).

We recently advised a German citizen who held permanent residency in Mexico and had been living in the country for several years. His business activities, management functions, and primary source of income were all based in Mexico, making him a Mexican tax resident under Mexican tax law.

The client planned to transfer funds from Germany to Mexico to purchase land and build a personal residence. The funds consisted of savings accumulated during many years of employment in Germany before relocating to Mexico.

Although the principal amount had already been taxed in Germany when it was originally earned, there was an important issue that required analysis: the interest income generated by those German bank accounts during the years in which the taxpayer was already considered a Mexican tax resident.

The Importance of Documenting the Source of Funds

Before transferring significant amounts of money into Mexico, it is advisable to maintain sufficient documentation to support the legal source of the funds and their tax history.

In this case, we reviewed and organized:

• German tax returns.
• Historical bank statements.
• Evidence that taxes had been paid in Germany.
• Certified translations of relevant documents.
• Banking records demonstrating the accumulation and retention of the funds over time.

The objective was to establish that the funds were not undeclared recent income, but rather savings accumulated through prior employment in Germany.

Foreign Interest Income May Be Taxable in Mexico

During our review, we identified that the German bank accounts had generated interest income while the taxpayer was already a Mexican tax resident.

Since Mexico taxes its residents on worldwide income, this interest income was required to be reported in Mexico, even though the funds remained deposited in Germany.

To correct the situation, the interest earned during the relevant tax years was calculated and the appropriate amended tax returns were prepared.

Applying the Mexico-Germany Tax Treaty

One of the most common concerns in international tax matters is double taxation.

For that reason, we reviewed the tax treaty between Mexico and Germany to determine whether foreign taxes paid on the interest income could be credited against Mexican tax liabilities.

The treaty provisions helped determine the correct Mexican tax treatment and allowed the taxpayer to avoid being taxed twice on the same income, subject to the applicable limitations and documentation requirements.

When Do You Become a Mexican Tax Resident?

A common misconception is that tax residency depends solely on holding a temporary or permanent residency permit.

In reality, Mexican tax residency is determined by several factors, including the following:

Permanent Home in Mexico

Individuals who establish a permanent home in Mexico may become Mexican tax residents.

Center of Vital Interests

A person may also be considered a Mexican tax resident if their center of vital interests is located in Mexico.

This generally applies when:

• More than 50% of their total income is derived from Mexican sources; or
• Mexico is the primary location from which they conduct their professional activities.

Principal Place of Professional Activities

Even when most income is generated outside Mexico, an individual may still be considered a Mexican tax resident if they manage, direct, or perform their primary business or professional activities from within Mexico.

For example, a foreign consultant living in Guadalajara who provides services exclusively to overseas clients may still be considered a Mexican tax resident, despite having no Mexican customers.

Building a Home in Mexico Using Foreign Funds

Foreigners who wish to purchase land or build a home in Mexico using funds accumulated abroad should carefully review:

• Their current tax residency status.
• Worldwide income reporting obligations.
• Applicable tax treaties.
• Source-of-funds documentation.
• Foreign income disclosure requirements.
• Future tax implications when selling the property.

Proper planning can significantly reduce tax risks and help support the legitimacy and origin of transferred funds if questions arise from financial institutions or tax authorities.

Conclusion

Mexican tax residency involves much more than simply obtaining a temporary or permanent immigration status. Individuals who live in Mexico and conduct their business or professional activities from the country are often subject to Mexican taxation on their worldwide income.

Before transferring savings, investments, or accumulated wealth from another country into Mexico for the purchase of land or construction of a residence, it is advisable to analyze the tax implications, properly document the source of funds, and ensure compliance with reporting obligations in both jurisdictions.

La entrada German Citizen Living in Mexico: A Practical Tax Residency and Worldwide Income Case Study se publicó primero en TAX ID.

Recientemente asesoramos a un ciudadano alemán con residencia permanente en México que llevaba varios años viviendo en el país. Su actividad económica, administración de negocios y fuente principal de ingresos se encontraban en México, por lo que ya era considerado residente fiscal mexicano.

El contribuyente deseaba transferir recursos desde Alemania para adquirir un terreno y posteriormente construir una casa habitación en México. El origen de los fondos provenía de ahorros acumulados durante años de trabajo en Alemania antes de mudarse al país.

Aunque el capital principal ya había pagado impuestos en Alemania en el momento en que fue generado, existía un aspecto importante que debía analizarse: los intereses generados por dichas cuentas de ahorro durante los años en que el contribuyente ya era residente fiscal en México.

La importancia de acreditar el origen de los recursos

Antes de transferir cantidades importantes a México, es recomendable contar con documentación suficiente que permita demostrar el origen lícito de los recursos y su historial fiscal.

En este caso se recopilaron:

• Declaraciones fiscales presentadas en Alemania.
• Estados de cuenta bancarios históricos.
• Evidencia del pago de impuestos realizado en Alemania.
• Traducciones de la documentación relevante.
• Estados de cuenta que demostraban la permanencia de los fondos en las instituciones financieras alemanas.

La finalidad era demostrar que el dinero no correspondía a ingresos recientes no declarados, sino a ahorros acumulados durante años de actividad laboral en Alemania.

Los intereses generados en el extranjero también pueden estar gravados en México

Durante la revisión se detectó que las cuentas bancarias alemanas habían generado rendimientos financieros mientras el contribuyente ya era residente fiscal mexicano.

Debido a que México grava a sus residentes sobre sus ingresos mundiales, dichos intereses debían ser declarados en México, aun cuando los fondos permanecieran depositados en Alemania.

Para regularizar la situación se calcularon los intereses obtenidos en cada ejercicio y se presentaron las declaraciones complementarias correspondientes.

Aplicación del Tratado para Evitar la Doble Tributación entre México y Alemania

Uno de los principales riesgos en situaciones internacionales es la doble tributación.

Por ello se revisó el convenio celebrado entre México y Alemania para evitar la doble imposición. Dicho tratado permite, bajo determinadas condiciones, acreditar en México el impuesto pagado en Alemania sobre ciertos tipos de ingresos.

Esto permitió determinar correctamente el impuesto mexicano correspondiente y evitar que el contribuyente pagara impuestos dos veces sobre los mismos rendimientos.

¿Cuándo una persona se vuelve residente fiscal en México?

Un error frecuente es pensar que la residencia fiscal depende exclusivamente de contar con una visa temporal o permanente.

En realidad, la legislación mexicana establece diversos criterios para determinar la residencia fiscal. Entre los más relevantes se encuentran:

Casa habitación en México

Si una persona establece su casa habitación en territorio nacional, puede adquirir la condición de residente fiscal mexicano.

Centro de intereses vitales

También puede considerarse residente cuando su centro de intereses vitales se encuentra en México.

Generalmente esto ocurre cuando:

• Más del 50% de sus ingresos totales provienen de México.
• El centro principal de sus actividades profesionales se encuentra en el país.

Centro principal de actividades profesionales

Incluso cuando la mayoría de los ingresos provienen del extranjero, una persona puede ser considerada residente fiscal mexicana si desde México dirige, administra o desarrolla de manera habitual sus actividades profesionales o empresariales.

Por ejemplo, un consultor extranjero que vive en Guadalajara y presta servicios a clientes ubicados en otros países podría seguir siendo residente fiscal mexicano, aun cuando ninguno de sus clientes se encuentre en México.

Construir una casa en México con recursos provenientes del extranjero

Cuando un extranjero desea adquirir un terreno o construir una casa habitación en México utilizando recursos acumulados en otro país, es recomendable realizar una revisión previa de:

• Residencia fiscal actual.
• Obligaciones de declaración de ingresos mundiales.
• Tratados para evitar la doble tributación.
• Documentación de origen de recursos.
• Posibles obligaciones informativas.
• Implicaciones futuras en caso de venta del inmueble.

Una adecuada planeación puede evitar diferencias con las autoridades fiscales y facilitar la justificación del origen de los recursos cuando éstos sean transferidos a México.

Conclusión

La residencia fiscal en México va mucho más allá de contar con una visa temporal o permanente. Una persona que vive, administra sus negocios y desarrolla sus actividades profesionales desde México generalmente estará obligada a declarar sus ingresos mundiales.

Antes de transferir ahorros, inversiones o patrimonio acumulado en otro país para comprar un inmueble o construir una casa en México, es recomendable analizar la situación fiscal internacional, documentar adecuadamente el origen de los recursos y verificar el correcto cumplimiento de las obligaciones tributarias en ambos países.

The Common Mistake: The 183-Day Rule

One of the biggest myths is thinking that the 183-day rule automatically determines tax residency in Mexico. Unlike many other countries, Mexican legislation follows different criteria.

According to Article 9 of the Federal Tax Code (CFF), an individual is considered a tax resident in Mexico if they have established their habitual dwelling (casa habitación) in Mexican territory. When the person also has a home in another country, the key factor becomes the center of vital interests.

Center of Vital Interests: What Really Matters

Mexican law establishes that a person has their center of vital interests in Mexico when, among other factors:

• More than 50% of their total income comes from Mexican sources, or
• Their center of main professional activities is located in Mexico.

The concept of “center of main professional activities” is analyzed case by case. It generally applies when a person:

• Regularly performs their work or professional activities from Mexico
• Makes key economic and business decisions in the country
• Uses Mexican infrastructure (office, team, technology, etc.) for their daily operations

Important: These criteria are independent. A person can receive 100% of their income from abroad and still be classified as a Mexican tax resident.

Real Case: British Citizen with Permanent Residency in Mexico

We recently worked with a client born in England who held permanent residency in Mexico. His income came from a UK company and was deposited into English bank accounts. He would then transfer funds to Mexico for living expenses.

Although none of his income was generated in Mexico, he had:

• Established his habitual dwelling in Mexico
• No permanent home in the United Kingdom
• Conducted his professional activities daily from Mexican territory

After a thorough analysis, we determined he was a tax resident in Mexico. We collaborated with a UK tax advisor, who confirmed he no longer qualified as a tax resident in the UK. We then proceeded with the formal change of tax residency.

Positive Outcome: Significant Tax Savings with RESICO

The regularization process proved highly beneficial. Thanks to the nature of his activities, the client qualified for the Régimen Simplificado de Confianza (RESICO), achieving a much lower effective tax rate than in the UK.

When a Foreigner Is NOT Automatically a Tax Resident

Not every foreigner with connections to Mexico becomes a tax resident. For example:

• A person with temporary residency who buys a property for occasional vacations
• Someone who rents their property on Airbnb a few weeks per year
• Individuals who maintain their permanent home, family, and professional activities abroad

In these cases, they usually remain tax residents of their home country and only pay taxes in Mexico on Mexican-source income (such as rental income).

Key Factors Tax Authorities Consider

• Location of habitual dwelling
• Center of main professional activities
• Family and economic ties
• Immigration status (temporary vs. permanent residency)
• Applicable double taxation treaties
