Mexican VAT returns

Once registered for value added tax (VAT) in Mexico (Impuesto al Valor Agregado – IVA), businesses must declare all taxable transactions and remit any VAT due to the Servicio de Administración Tributaria (SAT), Mexico’s federal tax authority.

Mexican VAT returns are generally filed on a monthly basis.

• Monthly filing is the standard requirement for most resident and nonresident VAT-registered businesses.
• There is no routine bi-monthly or quarterly VAT return cycle under Mexican VAT law.
• Filing frequency is not elective; VAT returns must be submitted for each calendar month in which taxable activities occur.

The SAT assigns VAT filing obligations as part of the taxpayer’s federal registration and ongoing compliance profile.

Mexican VAT returns must generally be submitted by the 17th day of the month following the end of the reporting period.

VAT payments for the period are due by the same deadline.

For example, VAT for January must usually be declared and paid by 17 February.
If the due date falls on a weekend or public holiday, the deadline may shift in accordance with SAT administrative rules.

VAT-registered businesses in Mexico must maintain comprehensive tax and accounting records, including:

• Electronic tax invoices (CFDI) issued and received
• Sales and purchase records supporting VAT calculations
• Import and export documentation
• Accounting books and journals aligned with Mexican electronic accounting rules
• Digital records required for SAT reporting and audits

Records must generally be retained for at least five years and be made available to the SAT upon request.

VAT payments are due on the same date as the VAT return filing deadline (generally, the 17th day of the following month).

Late payments may result in:

• Surcharges (recargos) on unpaid VAT
• Fines and penalties
• Possible enforcement measures, including restrictions on digital certificates used for invoicing

Input VAT may generally be credited against output VAT where expenses are directly related to taxable business activities, including:

• Goods purchased for resale
• Capital assets and business equipment
• Professional services, utilities, and operating costs
• VAT paid on imports of goods used in taxable activities
• Pro rata deductions for mixed-use expenses where permitted

To be deductible, input VAT must:

• Be supported by a valid CFDI
• Be properly recorded in the taxpayer’s accounting records
• Relate to VAT-taxable (or zero-rated) activities

VAT is not deductible on private expenses or expenses related exclusively to exempt activities.

All Mexican VAT returns must be filed electronically through the SAT’s online portal using the taxpayer’s digital credentials.

VAT payments are typically made via:

• Electronic bank transfer
• Authorised payment platforms linked to the SAT

Penalties may apply for VAT noncompliance, including:

• Fines for late or missing VAT returns
• Surcharges and interest on late VAT payments
• Penalties for incorrect, incomplete, or misleading filings
• Additional sanctions for repeated non-compliance or tax evasion

The SAT publishes administrative guidance on applicable penalties, surcharges, and enforcement measures, which may change over time.

If input VAT exceeds output VAT for a given reporting period, the resulting credit may be:

• Carried forward to offset future VAT liabilities, or 
• Refunded through a formal refund request submitted to the SAT

VAT refunds are subject to review and verification by the SAT. Processing times can vary, and refunds may be delayed if additional documentation is requested or if the taxpayer is selected for audit.
