¿Qué es la utilidad contable?

La utilidad contable es el resultado que se obtiene en los estados financieros conforme a normas contables.

Se calcula así:

Ingresos – Costos – Gastos = Utilidad contable

Refleja la rentabilidad financiera del negocio y es la que normalmente se presenta en:

• Statement of income
  
• Reportes para socios
  
• Análisis bancarios
  
• Evaluaciones de desempeño
  

Es la utilidad que “se ve” en la contabilidad.

¿Qué es la utilidad fiscal?

La utilidad fiscal es la base sobre la cual se calcula el ISR (Impuesto Sobre la Renta). Se determina conforme a la Ley del ISR y bajo los criterios del Servicio de Administración Tributaria.No se basa únicamente en el resultado contable. Se ajusta con reglas fiscales específicas.

¿Por qué son diferentes?

Porque la ley fiscal no reconoce todos los ingresos ni todas las deducciones exactamente igual que la contabilidad.

Existen diferencias como:

• Gastos no deducibles
  
• Deducciones limitadas
  
• Depreciaciones fiscales distintas a las contables
  
• Ajuste anual por inflación
  
• Pérdidas fiscales de ejercicios anteriores
  
• Anticipos y acumulación de ingresos bajo reglas fiscales
  

Por eso, una empresa puede tener:

-Utilidad contable baja y utilidad fiscal alta
-Utilidad contable alta y utilidad fiscal baja
-Incluso pérdida contable pero utilidad fiscal

Practical example

Supongamos que una empresa tiene:

Utilidad contable: $1,000,000

Pero incluye:

• Gastos no deducibles por $150,000
  
• Diferencia en depreciación por $80,000
  
• Ajuste anual por inflación acumulable por $70,000
  

La utilidad fiscal sería mayor a la contable, y el ISR se calcularía sobre esa base ajustada.El resultado:
Más impuesto del que el empresario esperaba.

Impacto en la Declaración Anual

En la Declaración Anual de Personas Morales, no se parte directamente del estado de resultados contable.

Se realiza una conciliación contable-fiscal donde se:

• Suman partidas no deducibles
  
• Restan deducciones fiscales permitidas
  
• Ajustan diferencias temporales
  
• Determina la base gravable
  

Sin esa conciliación, el cálculo puede ser incorrecto.

¿Por qué esto es clave para la planeación?

Muchos empresarios toman decisiones basadas en la utilidad contable:

• Reparto de dividendos
  
• Inversiones
  
• Contrataciones
  
• Expansión
  

Pero si no consideran la utilidad fiscal, pueden enfrentarse a:

• Falta de flujo para pagar ISR
  
• Pagos provisionales elevados
  
• Ajustes inesperados en cierre de ejercicio
  

La utilidad fiscal impacta directamente el flujo de efectivo.

Error común: no proyectar la utilidad fiscal

Muchas empresas descubren su utilidad fiscal hasta el cierre anual.

Una estrategia adecuada implica proyectarla durante el año para:

• Anticipar carga tributaria
  
• Optimizar deducciones
  
• Ajustar pagos provisionales
  

Evitar sorpresas en marzo.

Conclusion

La utilidad contable mide el desempeño del negocio. La utilidad fiscal determina cuánto impuesto pagarás. Confundirlas puede afectar tu flujo, tu planeación y tu crecimiento. Las empresas que gestionan estratégicamente sus finanzas no esperan al cierre del ejercicio para conocer su resultado fiscal. Lo proyectan, lo analizan y lo optimizan con anticipación.

Si deseas revisar tu conciliación contable-fiscal o proyectar tu utilidad fiscal antes del cierre anual, en TAXID podemos ayudarte a estructurar un análisis preventivo y estratégico.

Legal framework of the IEPS

The IEPS is a federal tax regulated and supervised by the Tax Administration Service.

In the case of alcoholic beverages, it taxes the sale or importation of products with alcoholic content.

But responsibility changes depending on the role within the chain.

1️⃣ Producer before the IEPS

The producer is the one who:

• Manufactures or processes alcoholic beverages within the national territory
  
• It has control over the production process
  
• He is responsible for compliance at the source.
  

Main obligations:

• Registration in the Register of Alcoholic Beverages
  
• Volumetric control
  
• Monthly declaration and payment of IEPS
  
• Correct issuance of CFDI with itemized IEPS
  
• Inventory control
  
• Label compliance (where applicable)
  

Risk level:

High.
The producer is the first one obligated in the chain and carries the greatest regulatory burden.

2️⃣ Marketer before the IEPS

The marketer is the one who:

• Buy pre-produced alcoholic beverages
  
• She sells them in the national market
  
• It does not participate in the production process
  

Does it pay IEPS?

Generally, the IEPS (Special Tax on Production and Services) is already included in the purchase price for the producer.

The marketer does not recalculate IEPS for production, but must:

• Transfer the tax correctly
  
• Issue appropriate CFDI
  
• Maintain supporting documentation
  
• Fulfill control obligations if you are registered
  

Risk level:

Half.
The main risk lies in errors in transfer, billing and documentation.

3️⃣ Importer before the IEPS

The importer is the one who:

• It brings alcoholic beverages into the country
  
• Perform customs clearance
  
• He is responsible for the tax at the time of importation
  

Main obligations:

• IEPS payment at customs
  
• Compliance with health regulations
  
• Registration in sectoral registers
  
• Subsequent declaration in domestic transactions
  
• Inventory control
  

Risk level:

High.
The IEPS is paid at the time of import, which directly impacts cash flow.

Key differences between the three figures

Common mistake: structuring the operation incorrectly.

Many new brands believe they can operate as “marketers” when in reality they assume the functions of a producer.

Or they import products without analyzing them:

• Financial impact of the IEPS on customs
  
• Need for a census
  
• Labeling requirements
  
• Volumetric control
  

A poor structure can cause:

• Suspension of censuses
  
• Fines
  
• Tax credits
  

Retention of goods in customs

What happens if you manufacture?

In maquila schemes, it is essential to define:

• Who is the legal producer?
  
• Who assumes the IEPS?
  
• How are transactions documented?
  
• How the tax is passed on
  

Lack of contractual clarity can generate shared contingencies.

Conclusion

Regarding the Special Tax on Production and Services (IEPS), the difference between producer, distributor, and importer is not only operational. It is fiscal and regulatory. Before launching or expanding an alcoholic beverage brand in Mexico, it is essential to correctly define your role within the supply chain. A poorly designed structure can generate problems from the very first month of operation.

If you are about to launch, import or structure your brand in Mexico, at TAXID we can help you define the appropriate tax strategy and prevent risks before starting operations.

Sin embargo, no todas las comunicaciones implican una auditoría formal. Una de las más comunes es la carta invitación. Entender qué es y cómo responderla correctamente puede marcar la diferencia entre cerrar el tema rápidamente o escalar a una revisión más profunda.

¿Qué es una carta invitación?

Una carta invitación es un comunicado preventivo que envía el SAT cuando detecta inconsistencias en la información fiscal de un contribuyente.

No es una auditoría.
No es un crédito fiscal.
No es una multa automática.

Es una advertencia.

El SAT utiliza cruces electrónicos de información (CFDI, declaraciones, DIOT, pagos provisionales, etc.) y cuando identifica diferencias, envía esta comunicación para que el contribuyente:

• Revise su información
• Corrija voluntariamente
• Presente declaraciones complementarias si es necesario

¿Por qué llega una carta invitación?

Las causas más comunes son:

• Diferencias entre CFDI emitidos y lo declarado
• IVA trasladado distinto al declarado
• Deducciones sin soporte digital válido
• Pagos provisionales inconsistentes
• Operaciones con proveedores con irregularidades
• Discrepancias entre declaraciones mensuales y anual

En muchos casos, el error no es intencional, pero sí detectable.

¿Qué pasa si la ignoras?

Aunque la carta invitación no es una auditoría formal, ignorarla puede provocar:

• Revisión electrónica
• Requerimientos formales
• Fines
• Determinación presuntiva de ingresos
• Inicio de facultades de comprobación

El SAT suele dar un plazo para revisar o aclarar. No responder aumenta el riesgo.

Cómo responder correctamente una carta invitación

1️⃣ No entrar en pánico

Lo primero es analizar técnicamente el motivo.
No todas las cartas implican que exista un adeudo real.

2️⃣ Revisar la información fiscal completa

Es necesario:

• Conciliar CFDI emitidos vs declaraciones
• Revisar IVA acreditable
• Validar deducciones
• Verificar pagos provisionales
• Confirmar que no haya errores de captura

Muchas veces el problema es un desfase o clasificación incorrecta.

3️⃣ Determinar si procede una corrección

Si efectivamente existe diferencia, lo recomendable suele ser:

• Presentar declaración complementaria
• Regularizar pagos
• Cubrir actualización y recargos voluntariamente

Corregir antes de una auditoría reduce riesgos mayores.

4️⃣ Si no existe diferencia, preparar aclaración técnica

En caso de que la información esté correcta:

• Se puede presentar aclaración
• Documentar soportes
• Justificar técnicamente la operación

La respuesta debe ser estructurada, no improvisada.

¿Cuándo se vuelve un riesgo mayor?

Una carta invitación puede escalar si:

• Existen diferencias reiteradas
• Hay inconsistencias en varios ejercicios
• La empresa tiene alto volumen de operaciones
• Se detectan proveedores con irregularidades
• Se ignoran comunicaciones previas

Por eso es clave atenderla con estrategia.

Diferencia entre carta invitación y auditoría

Responder bien una carta invitación puede evitar llegar a la segunda etapa.

La clave: prevención continua

Las empresas que reciben cartas invitación frecuentemente suelen tener:

• Falta de conciliaciones mensuales
• Controles internos débiles
• Cierre anual sin revisión preventiva

Implementar revisiones periódicas reduce significativamente el riesgo.

Conclusion

Una carta invitación no es una sentencia, pero sí es una señal de alerta. Ignorarla puede convertir un ajuste menor en una contingencia mayor. La mejor estrategia no es reaccionar cuando llega la notificación, sino prevenir inconsistencias antes de que el SAT las detecte.

Si tu empresa recibió una carta invitación o deseas realizar una revisión preventiva para detectar posibles riesgos, en TAXID podemos ayudarte a analizar tu situación fiscal con un enfoque técnico y estratégico.

In Mexico, the accounting period usually coincides with the fiscal year (January 1 to December 31). However, start the process in advance This is what makes the difference: it allows for timely adjustments, planning of tax strategies, identification of risks, and the presentation of consistent and useful financial statements for management, investors, and authorities.

The importance of starting early

One of the most common mistakes companies make is waiting until the end of the fiscal year to begin the closing process. Starting in November, or even earlier, provides a critical window for:

• Design a tax strategy (deferral of income, application of incentives or tax benefits).
• Evaluate the deductibility of expenses and make investment decisions before the end of the year.
• Adjust accounting policies related to employee benefits, deferred taxes, or asset impairment.
• Identify errors accumulated during the year and correct them without time pressure.

Key technical aspects of year-end closing

1. Review of accounts receivable and aging of balances

• Prepare a customer balance aging analysis (0-30, 31-60, 61-90, 91+ days).
• Evaluate the recoverability of overdue accounts and recognize provisions for uncollectible accounts in accordance with the NIF C-3.
• Review outstanding customer advances and confirm with balance letters.

2. Review of accounts payable and suppliers

• Confirm the age of liabilities and classify debts as short-term and long-term.
• Verify advances to suppliers and its correct reclassification against inventories or expenses.
• Review goods in transit and its proper recognition in accordance with the NIF C-4 Inventories.

3. Provisions and benefits for employees

• Register Christmas bonus, vacation pay, vacation bonus and profit sharing payable.
• Apply the NIF D-3 (Employee benefits), recognizing short-term and long-term labor liabilities.
• In companies with pension schemes or post-employment benefits, record the obligations based on actuarial calculations.

4. Recognition of deferred taxes

• Apply the NIF D-4 (Income Taxes) to identify time differences between accounting and tax results.
• Calculating deferred tax assets and liabilities, which directly impacts tax planning.
• Evaluate whether they exist Tax losses pending amortization that should be reflected in the financial statements.

5. Depreciation, amortization and impairment of assets

• Check that the tax depreciation coincide with the limits of the LISR and reconcile it with the accounting depreciation.
• Identify assets that require impairment testing (NIF C-15).
• Confirm amortization of intangibles, deferred charges and pre-operating expenses.

6. Comprehensive conciliations

• Accounting and tax reconciliation: determine the taxable profit and compare it with the accounting profit.
• Bank reconciliation: Identify items in transit, unapplied deposits, and outstanding checks.
• Inventory reconciliationPhysical vs. accounting validation, identification of obsolete items and necessary adjustments.

7. Review of notes to the financial statements

The year-end closing process doesn't end with the balance sheet and income statement. It's necessary to include notes that disclose:

• Accounting policies applied.
• Legal or tax commitments and contingencies.
• Related party information.
• Events after the reporting period (NIF B-13).

Benefits of a comprehensive year-end closing

A closure carried out with methodology and anticipation offers tangible advantages:

• Tax and regulatory compliance without risk of sanctions.
• Reliable information for strategic decision-making.
• Better tax planning (possibility of deferring taxes or taking advantage of deductions).
• Access to financing, because banks and investors place more trust in solid financial statements.
• Risk prevention, by identifying legal, tax, or labor contingencies before they become a problem.

Conclusions and recommendations

The annual accounting close should be viewed as a investment in the company's financial health, not just as an obligation. The earlier it is done, the more room there will be to plan, correct, and optimize.

In Tax ID Mexico, We help our clients prepare solid accounting and tax closings, integrating current regulations (NIF and tax laws), with a focus on planning and financial analysis that truly drives business growth.

1. The RFC Requirement

In order to sell on Amazon Mexico—or on any marketplace that issues official tax invoices (CFDI)—you will need to register with Mexico’s Tax Authority (SAT) and obtain a RFC (Federal Taxpayers Registry). This is Mexico’s tax ID, and without it you will not be able to properly invoice or comply with VAT (IVA) obligations.

2. Entity Formation Options

You generally have two options when entering the Mexican market:

• Form a new Mexican company (e.g., an S.A. de C.V. or an S.A.S.):
  This is the recommended route for most sellers. It allows you to maintain limited liability in Mexico, provides clearer tax treatment, and is recognized by banks and authorities.
• Register a foreign company in Mexico:
  While technically possible, this option is rarely recommended. The process is more complicated, involves higher legal and bureaucratic hurdles, and—most importantly—you lose the benefits of limited liability within Mexico. In practice, it creates more risk and more ongoing administrative costs.

3. Legal Representative and Physical Address

Regardless of which option you choose, you must appoint a legal representative in Mexico. This person is empowered to act on behalf of your business with the tax authorities, banks, and other institutions.

Additionally, you must provide a physical business address in Mexico. Even if your business does not require infrastructure or staff in the country, the authorities require a verifiable address. The SAT (tax authority), banks, and sometimes customs officials may physically verify this address as part of their compliance checks.

4. Compliance Costs and Verification Requirements

One of the hidden challenges for Amazon sellers is the high cost of compliance in Mexico. For example:

• Address verification: The SAT may require physical inspections of your registered office.
• Bank requirements: Opening a corporate bank account generally requires on-site verification.
• Importation licenses: Bringing goods into Mexico requires compliance with customs and may involve product labeling, NOM certifications, or additional permits.
• Accounting and tax compliance: Monthly VAT filings, payroll (if you hire staff), and annual corporate reporting all create recurring expenses.

These requirements mean that even if you operate “virtually,” you must budget for ongoing compliance infrastructure.

5. Forecasting Before Entering the Market

Before setting up in Mexico, it is strongly recommended to prepare a financial forecast. Consider:

• Entity formation or foreign registration costs
• Legal representative fees
• Ongoing compliance costs (accounting, SAT filings, bank requirements)
• Importation duties, logistics, and certifications
• Amazon commissions and platform fees
• Expected monthly sales volumes in Mexico

By modeling these costs against your projected sales, you can evaluate whether expansion into Mexico is financially viable.

6. Key Takeaways

• Selling on Amazon Mexico requires an RFC and formal registration with the tax authorities.
• Setting up a Mexican entity is usually more efficient than registering a foreign company.
• You will need a local legal representative and a verifiable physical address.
• Compliance costs can be high, particularly due to physical inspections and banking requirements.
• A careful financial forecast is essential before making a decision.

Expanding into Mexico can be profitable, but success depends on careful planning, realistic budgeting, and professional guidance. For many U.S. sellers, partnering with a local accounting or legal firm is the most efficient way to reduce risks and ensure smooth operations.

In Mexico, the digital stamps They are essential for issuing electronic invoices (CFDI) and complying with tax obligations. If the Tax Administration Service (SAT) detects irregularities in your tax situation, it may restrict or cancel your stamps, which slows down billing and directly affects the operation of your business. In this article you will learn about the most common causes of cancellation, the preventive measures and what to do if it's already happened to you.

Why is the SAT canceling digital stamps?

The SAT may restrict the use of stamps when it identifies any of these scenarios:

1. Omission in tax returns Failure to file monthly or annual returns on time, even if you had no income.
   
2. Tax inconsistencies
   Differences between what you declare and what appears on your issued and received CFDIs.
3. Firm tax debts
   Debts with the SAT that have not been paid or guaranteed.
4. Non-existent operations
   Engage with companies listed in Article 69-B of the CFF (invoicing companies or EFOS).
5. Tax address not located
   Incorrect or outdated address on the SAT portal.
   

Consequences
of the cancellation

If the SAT cancels your digital stamps, you could face:

• Inability to issue electronic invoices.
  
• Loss of customers who require CFDI.
  
• Fines, surcharges and tax audits.
  
• Temporary blocking of commercial operations.
