Business Expense Policy Mexico (Política de Gastos de Representación)

A Business Expense Policy Mexico (Política de Gastos de Representación or Política de Gastos de Viaje y Representación) is a corporate governance document that establishes the rules, limits, authorisation requirements, and reimbursement procedures for business expenses incurred by employees, officers, and directors on behalf of the company — including travel costs (gastos de viaje), client entertainment (gastos de atención a clientes), meals (alimentos de negocios), accommodation (hospedaje), transportation, and other legitimate business expenditures — within the tax deductibility framework established by the Ley del Impuesto Sobre la Renta (LISR) and the Código Fiscal de la Federación (CFF).

The primary tax law framework governing business expense deductibility in Mexico is the Ley del Impuesto Sobre la Renta (LISR, DOF 11 December 2013, as reformed), which establishes in Article 25 the general rule that expenses are deductible for income tax (ISR) purposes when they are strictly indispensable (estrictamente indispensables) for the business activities generating taxable income — meaning the expense must have a clear nexus to the generation of revenue and must not be a personal expense of the employee or director being reimbursed. Article 28 LISR establishes specific limitations on the deductibility of certain expense categories that a Business Expense Policy must observe.

LISR Article 28 Fraction XX limits the deductibility of representation expenses (gastos de representación) to 69% of the amount actually incurred — gastos de representación are broadly defined as expenses for meals, entertainment, gifts, and hospitality provided to clients, suppliers, and business contacts for business purposes. This 69% limitation means that MXN $100 spent on a business lunch with a client generates only a MXN $69 tax deduction, with the remaining MXN $31 being a non-deductible cost that the company bears without tax benefit. The 69% limitation applies to the net amount before IVA — the IVA (Impuesto al Valor Agregado) component of the expense is fully creditable as acreditable input tax against the company's IVA liability under the Ley del Impuesto al Valor Agregado (LIVA) Article 5, provided a valid CFDI 4.0 is obtained.

The Código Fiscal de la Federación (CFF) Article 29 establishes the mandatory documentation requirement for all deductible business expenses: a Comprobante Fiscal Digital por Internet (CFDI 4.0) — Mexico's electronic invoice system — issued by the supplier of the goods or services. Without a valid CFDI from a supplier whose RFC is active and not on the SAT's Art. 69-B blacklist, the expense cannot be deducted for ISR purposes. For expenses abroad (gastos en el extranjero), LISR Article 28 Fraction III provides that foreign invoices are deductible when accompanied by a sworn declaration (declaración escrita bajo protesta de decir verdad) that the expense was incurred for business purposes and meets the LISR deductibility requirements.

For travel expenses (gastos de viaje) of employees, LISR Article 28 Fraction V establishes deductibility limits for per diem payments (viáticos): for domestic travel within Mexico, the deductible daily allowance per person is up to MXN $750 for accommodation and MXN $200 for food when travel is outside a 50-kilometre radius of the employee's regular workplace; for international travel, higher limits apply based on SAT Anexo 7 de la Resolución Miscelánea Fiscal (RMF). Per diem payments exceeding LISR limits are treated as taxable income (ingreso gravable) of the employee under LISR Article 94, which the company must withhold ISR and report to the SAT.

The intersection of the Business Expense Policy with the Anti-Corruption Policy (Política Anticorrupción) is critical in Mexico's post-LGSNA compliance environment: expenses for gifts, meals, and entertainment provided to government officials (servidores públicos) are subject to stringent limits under the Ley General de Responsabilidades Administrativas (LGRA) Article 14 — any gift or hospitality to a public official that could influence their official conduct constitutes cohecho (bribery) under the LGRA and Código Penal Federal Article 222 regardless of whether the expense is otherwise tax-deductible.

A Business Expense Policy Mexico is needed by any organisation whose employees, officers, or directors incur business expenses on the company's behalf that require reimbursement — establishing the controls and documentation requirements that are indispensable for both tax deductibility under the LISR and internal financial governance under Mexican accounting standards.

Any company subject to ISR (Impuesto Sobre la Renta) — which under LISR Article 1 includes all resident legal entities and individuals with business income in Mexico — needs a Business Expense Policy to document that expenses claimed as deductions meet the 'estrictamente indispensable' standard of LISR Article 25, and to implement the CFDI 4.0 documentation requirements of CFF Article 29 for all deductible expense claims.

Companies with travelling sales teams (fuerzas de ventas), client service teams, or field operations staff need the policy to control and document travel expenses — establishing per diem rates consistent with LISR Article 28 Fraction V deductibility limits, accommodation booking procedures, transportation policies (air travel class, taxi vs. ride-share), and documentation requirements that enable SAT audit defence.

Organisations that provide entertainment to clients and suppliers — including business meals (comidas de negocios), sporting event tickets, cultural events, and corporate gifts (regalos empresariales) — need the policy to enforce the LISR Article 28 Fraction XX limitation on representation expense deductibility and the anti-corruption policy limits on gifts to government officials under the Ley General de Responsabilidades Administrativas (LGRA).

Companies that issue corporate credit cards (tarjetas corporativas) to employees need an expense policy that defines authorised uses of corporate cards, documentation requirements for card charges, procedures for disputing fraudulent charges, and consequences for misuse — including the employer's right to charge improper expenses back to the employee's salary under LFT Article 110 Fraction III (with employee's written consent).

Branches and subsidiaries of foreign multinational companies operating in Mexico need a local Business Expense Policy that translates global expense standards into the Mexican tax and regulatory context — ensuring that CFDI documentation requirements, LISR deductibility limits, and LGRA anti-corruption restrictions are built into the local reimbursement process, even when the global policy uses different frameworks.

Under LISR art. 28 Frac. XX and CFF art. 29, any company that claims business expense deductions must maintain documented expense policies and CFDI records — without a formal policy and proper CFDI documentation, the SAT may disallow expense deductions in a tax audit and impose back taxes, surcharges (recargos), penalties (multas), and inflation adjustments (actualización).

An effective Business Expense Policy Mexico compliant with the Ley del Impuesto Sobre la Renta (LISR) Article 28, the Código Fiscal de la Federación (CFF) Article 29, and the Ley General de Responsabilidades Administrativas (LGRA) must contain the following essential elements:

Scope and Eligible Expenses: A clear definition of which employees and business purposes qualify for expense reimbursement — specifying that expenses must be (a) directly related to the company's business activities and generation of taxable income (estrictamente indispensables under LISR Article 25), (b) authorised in advance by the appropriate level of management (unless emergency circumstances prevent prior approval), (c) reasonable and consistent with market rates, and (d) documented with a valid CFDI 4.0 from the supplier under CFF Article 29.

Expense Categories and Limits: Specific authorisation and reimbursement limits by expense category: travel (viajes) — maximum airfare class (economy for flights under 4 hours; business class with VP approval for international flights), daily accommodation limits by city tier (e.g., Ciudad de México $3,500 MXN/night, regional cities $2,000 MXN/night, subject to LISR Article 28 Fraction V deductibility limits), daily meal allowances consistent with LISR per diem limits ($200 MXN/day domestic, with SAT Anexo 7 international rates); business meals (comidas de negocios) — maximum amount per meal per person for client entertainment, requirement to record the business purpose and the names and company affiliations of all attendees, subject to the 69% deductibility limitation under LISR Article 28 Fraction XX; gifts (regalos) — maximum value per gift per recipient per year (e.g., $500 MXN for private sector recipients), absolute prohibition on cash gifts, prohibition on all gifts to government officials without prior Compliance Officer approval and verification of LGRA Article 14 compliance.

CFDI Documentation Requirements: The mandatory requirement that all expense reimbursement claims be supported by a CFDI 4.0 issued by the supplier in the company's name (Razón Social) and RFC — not in the employee's personal name. The CFDI must contain the correct SAT Clave de Producto o Servicio (CPS) code for the type of expense, the correct régimen fiscal of the supplier, and the employee's postal code if the CFDI is being issued to the company at the employee's work location. Expenses without CFDI (only a nota de venta or informal receipt) are reimbursable but not deductible for ISR purposes — the policy should specify how non-CFDI expenses are handled for accounting and tax purposes.

SAT Blacklist Verification: The requirement that all suppliers whose CFDIs are submitted for reimbursement be verified against the SAT's Art. 69-B lista definitiva (blacklist of companies issuing simulated invoices) before the expense is approved for reimbursement — because accepting a CFDI from a listed company eliminates the deductibility and may expose the company to SAT sanctions under CFF Article 69-B paragraph 8.

Expense Report Submission: The procedure for submitting expense reports — required format (papel or electronic expense management system), supporting CFDI attachments, business purpose description, attendee list for business meals and entertainment, submission deadline (e.g., within 15 business days of incurring the expense), and approval workflow (employee → direct supervisor → finance department). Expense reports submitted more than 30 days after the transaction date may not be deductible in the same fiscal period.

Corporate Credit Card Policy: Rules for authorised uses of company credit cards — prohibition on personal charges, requirement to submit expense reports for all card charges within the billing cycle, consequences for card misuse, and the company's right to offset improper charges against the employee's salary with written employee consent under LFT Article 110 Fraction III.

Government Official Restrictions: An absolute prohibition on any business meal, entertainment, gift, or hospitality provided to federal, state, or municipal government officials without the prior written approval of the Compliance Officer — reinforcing the LGRA Article 14 prohibition on improper benefits to public officials that constitute cohecho (bribery) under Código Penal Federal Article 222. Any approved expense involving a government official must be documented with the official's name, title, agency, and the legitimate business purpose of the interaction.

Reimbursement Timeline: The company's commitment to reimburse approved expenses within a defined period (typically 15 business days from approval) — and the employee's right to expedited reimbursement for travel advances (anticipos de viáticos) requested before a business trip.

Consequences of Misuse: Disciplinary consequences for expense policy violations — false expense claims (submitting personal expenses as business expenses, inflating amounts, or fabricating CFDIs) constitute fraud under CFF Article 108 and Código Penal Federal Articles 386 and 387, and are cause for summary termination without liability (rescisión sin responsabilidad patronal) under LFT Article 47 Fraction VIII.
