Mexican Tax Authorities Issue “Invitation Letters” to Taxpayers Regarding Alleged Discrepancies in Reporting Expense Deductions

By Rene Cacheaux, Miriam Name, and Esteban Gómez Aguado

Mexican tax authorities are sending notices to taxpayers inviting them to review and, if necessary, correct their tax filings (“Invitation Letters”). The Invitation Letters identify alleged discrepancies between amounts taxpayers claimed as authorized deductions and the expense and invoicing information they provided to support such deductions. It is important to review the Invitation Letter carefully because Mexico’s tax regulations provide for several legitimate deductions that do not necessarily tie into an Internet Digital Tax Invoice (“CFDI” for its acronym in Spanish). For example, investment deductions, annual adjustments for inflation, and exchange losses, among others, fall into this category. Legitimate discrepancies may also exist when a CFDI has been issued, but the deduction is filed for a different time period, such … read more

Mexico Creates Introductory Program to Audit Specialized Services

By Rene Cacheaux, Miriam Name and Esteban Gómez Aguado

A special tax resolution published in the Official Journal of the Federation on April 23, 2021, amends several current rules to establish that Mexican tax authorities will now disallow any credit or deductions for wages or other payments made for outsourced services that relate to the taxpayer company’s purpose and main economic activity. Once Mexico’s new Outsourcing Decree enters into force, such payments will be considered violations of the Decree. The Decree’s entry into force has been extended until September 1st, 2021. The General Federal Tax Auditor’s Office of the Mexican Tax Administration Service (“SAT”) has created an Introductory Program to Audit Specialized Services (the “Program”), designed to identify taxpayers with inconsistencies which could harm Mexico’s federal treasury. Mexico’s Federal … read more

By Miriam Name and Esteban Gómez Aguado

On December 8, 2020, Mexico published important new Miscellaneous Tax Rules amending numerous tax regulations in the Official Journal of the Federation. Article 30 of the Federal Tax Code is among the regulations amended, and the latest rules introduce new obligations with respect to maintaining supporting documents demonstrating the economic reasons behind corporate capital increases and decreases. In regard to capital increases resulting from a capitalization of liabilities, in addition to the corporate meeting minutes approving such increases, companies must also provide a certification that, from an accounting perspective, shows the existence of the liabilities and their corresponding values. The certification must be issued in compliance with the requirements set forth in the general rules issued by Mexican tax authorities … read more

Mexico Issues New Requirements for Reporting Increases in Capital

By Esteban Gómez Aguado

For Mexican entities approving capital stock increases or decreases occurring December 31, 2020 or before, Article 30 of the Mexican Federal Tax Code provided that taxpayers were required to maintain records of all minutes and certificates relating to such transactions. However, beginning January 1, 2021, Mexican tax authorities now may require additional information from Mexican entities evidencing the economic substance of the increases or decreases in their capital stock. Accordingly, taxpayers who increase their capital stock through the capitalization of liabilities must,  in addition to keeping accounting records, meeting minutes, account statements and, where appropriate, appraisals of the goods contributed, maintain a document certifying both the accounting existence of the liability in question and its value. Such certification must comply … read more

Mexico Modifies Rules for Reporting Intercompany Loans between Related Companies

By Esteban Gómez Aguado

On January 18, 2021, the Financial Intelligence Unit (“FIU”) of Mexico’s Tax Administration Service modified applicable rules governing loans made between entities that belong to the same business group.  This provides clarity to one of the most frequently asked questions regarding so called “vulnerable transactions” and mandatory compliance with the Federal Law for the Prevention and Identification of Transactions Conducted with Resources of Illicit Origin (“Anti-Money Laundering Law”). Put succinctly, the question is: “Will centralized treasury operations and/or intercompany loans made between companies from the same Business Group be considered vulnerable transactions?” Article 27 Bis, section I, subsection a) of the General Rules referred to in the Anti-Money Laundering Law (the “Rules”), establishes that loan transactions entered into between companies … read more

Mexico Now Requires Disclosure of Aggressive Tax Planning Transactions

By Miriam Name and Esteban Gómez Aguado

The Mexican omnibus tax bill for 2020 was published in the Official Journal of the Federation on December 9, 2019. Among other changes, a new Section, “Regarding the Disclosure of Reportable Transactions,” was added to the Mexican Federal Tax Code (“CFF” for its acronym in Spanish), which sets forth a mandatory disclosure or reporting requirement for certain transactions including or involving tax planning structures (“Reportable Transaction”). Depending on the date of implementation of the tax planning transaction and other factors, the tax planning transactions must be disclosed or reported by either the tax advisor involved or the corresponding taxpayer. The primary objective of the new reporting requirement is to prevent transactions that involve aggressive tax planning. As a practical matter, … read more

Considerations in Mexico Relating to Taxpayers Conducting Presumptively Non-Existent Transactions

By Esteban Gómez Aguado

Article 69-B of the Mexican Federal Tax Code sets forth a procedure to be followed by taxpayers who contract with suppliers of goods or services who, pursuant to public information published in the Official Journal of the Federation and on the Tax Administration Service website on a quarterly basis, are listed as companies that invoice simulated (non-existent) transactions (“EFOS” by its initials in Spanish). Compliance with the aforementioned procedure is important because if the veracity of a transaction is questioned and cannot be proven to have actually occurred, then the taxpayer’s tax receipts from the EFOS are considered null with no tax effect, meaning that the expenses may neither be deducted for income tax purposes nor creditable for value added … read more

Reductions in Estimated Income Tax Payments in Mexico

By Miriam Name and Esteban Gómez Aguado

The COVID-19 pandemic is causing a steep drop in revenues for Mexican companies during fiscal year 2020, which will also result in decreased net income and, in many cases, negative cash balances. Mexican companies will need to keep a close eye on their cash flow and analyze strategies and options to improve their cash balances. One strategy that should be considered involves a reduction of estimated income tax payments, paid on a monthly basis to cover the total annual income tax incurred. The estimated income tax payments for 2020 are being calculated based on an amount of net income that is potentially too high, compared to the likely net income that will actually be received this fiscal year. Article 14 … read more

Mexico Enacts Important Tax Law Changes Eliminating Universal Tax Credit Offsets

By Miriam Name and Edgar González

Mexico’s federal Congress recently enacted the 2019 Federal Revenue Law (the “Revenue Law”). An important change in Article 25, paragraph VI of the Revenue Law sets forth numerous limitations on tax credits, including an elimination of taxpayers’ ability to credit or offset all types of federal taxes against each other on a universal basis. The purpose of such new limitations is supposedly to combat tax evasion in Mexico. The Revenue Law now provides that taxpayers may “net out” positive balances against amounts owed only if both balances or amounts are for the same type of tax (e.g. Mexican income tax). The Revenue Law further provides that taxpayers with positive Value Added Tax balances may only credit or offset such tax … read more
