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.

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.

Conclusion

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 Simplified Trust Regime (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

• Temporary resident card
• Permanent resident card
• Border worker visitor card

Proof of address in Mexico (as listed in Annex 1-A of RMF 2025), such as:

What does REFIPRE mean?

REFIPRE is the abbreviation for Preferential Tax Regime, and refers to those countries or tax systems abroad where it is paid very little or almost no income taxThe Income Tax Law (article 176) establishes that a regime is considered preferential when it is paid less than the 75% of the ISR that would correspond in Mexico for the same income.

It's not just about the typical "tax havens," like the Cayman Islands or Belize. You can also apply to special regimes within well-known countries, such as certain areas in the United Arab Emirates, or even certain legal structures in the United States (such as an LLC in Delaware that doesn't pay taxes because it's a transit tax).

Why does the SAT care about this?

Because if a Mexican (individual or legal entity) earns money through a company, partnership, trust or other entity located in a REFIPRE, the SAT can force him to pay taxes in Mexico on that income, even if you haven't received them yet.

This is because Mexican law seeks to prevent taxpayers from using these countries to defer paying income tax or hide income. That's why there is a rule that These earnings must be accumulated in Mexico as if they had already been collected.

How do you know if you are operating with a REFIPRE?

There is no official list published by the SAT. In reality, you or your accountant should perform an analysis comparing how much income tax you would pay in that country versus what you would pay in Mexico. If the tax is less than 75%, then you are in a REFIPRE (Taxpayer Refund Policy), and tax obligations are triggered.

Also, if you have control or significant participation in a foreign entity, and it operates in a REFIPRE, the rule may also apply even if you have not received profits or dividends.

What happens if you have a company in a REFIPRE?

You have several important tax obligations:

• Keep separate accounting for income from REFIPRES.
• Accumulate that income in your annual tax return in Mexico, even if you haven't received it.
• Submit additional information returns.
• Adequately document the business purpose of the structure (Article 5-A of the Tax Code).
• Apply transfer pricing rules if there are transactions with related parties.

If you fail to comply, the SAT may reject deductions, presume fictitious income, and apply fines.

Which structures usually fall under REFIPRES?

Some common examples:

• Companies incorporated in Belize, Cayman Islands, United Arab Emirates, BVI, Panama or Andorra.
• Foreign trusts or foundations that accumulate income without paying it out.
• LLCs in the United States that do not pay taxes in that country or in Mexico.
• Digital platforms or services where income remains in a foreign entity with a low tax burden.

Care should also be taken with instruments such as SAFE (Simple Agreement for Future Equity), which if signed with entities in REFIPRES, must be analyzed in great detail to avoid tax risks.

Example of a common scheme with REFIPRE: alert for Mexican companies

One of the schemes that the SAT reviews the most occurs when a Mexican company provides services in national territory, but payments for those services They are not received directly in Mexico, but are diverted through a foreign company located in a REFIPRE.

Then, that money is repatriation to Mexico in the form of:

• Capital contributions
• Intercompany loans
• SAFE agreements (simple investment agreements)
• Purchase of shares
• Other financial instruments

This type of structure often lacks real economic substance and generates a high fiscal risk, since it can be interpreted as a simulation to avoid paying taxes in Mexico.

Conclusion

Using entities or structures in low-tax countries may seem attractive, but if not managed properly, they can result in fines, surcharges, and even extensive tax audits. Holding income abroad is not illegal, but must be done with knowledge and compliance.

If you have any doubts about whether you are operating under a REFIPRE or want to regularize your situation, it's best to review the case with an advisor specializing in international taxation. Tax ID Mexico We help individuals and corporations evaluate their structures and comply with all Mexican tax obligations.

3. Technical process for preparing a budget

a) Historical analysis and diagnosis

• Review of financial information from previous years.
• Identification of trends, seasonality and relevant deviations.
• Evaluation of key indicators: gross margins, EBITDA, liquidity ratio, collection and payment days, among others.

b) Definition of assumptions

Every budget starts from financial and operating assumptionsSome examples:

• Expected sales growth.
• Projected inflation.
• Exchange rate.
• Prices of key inputs.
• Hiring or investment policies.

c) Preparation by cost centers

• Budget by areas (sales, production, administration, etc.).
• Assign responsibilities by budget item.

• Use tools such as advanced Excel, Power BI or integrated ERPs (SAP, Odoo, Contpaqi).
• Update the budget quarterly or in response to relevant events.
• Ensure the participation of the financial area from the beginning of the process.

5. Common mistakes

• Projecting without considering historical information or market trends.
• Do not include documented assumptions.
• Underestimating recurring operating expenses.
• Lack of monthly follow-up.
• Isolated development without the participation of those responsible for each area.

6. Conclusion

The budget is a mechanism of control, planning and performance evaluation, and should be treated as a technical and strategic process, not a mere formality. Its proper development and implementation allows for anticipating risks, optimizing resources, and making informed decisions.
