Monthly IVA Return Mexico (Declaración Mensual de IVA)

The Monthly IVA Return Mexico (Declaración Mensual de IVA) is the periodic tax return filed by taxpayers registered under the Ley del Impuesto al Valor Agregado (LIVA) to report and remit the net Impuesto al Valor Agregado (IVA) — Mexico's value-added tax — arising from taxable activities performed during each calendar month. Article 5-D of the LIVA, published in the Diario Oficial de la Federación on 29 December 1978 and substantially reformed over subsequent decades, establishes that IVA taxpayers must calculate the monthly tax on an accrual basis (base devengada), determine the creditable input IVA (IVA acreditable) corresponding to expenses and acquisitions of that month, and submit the resulting declaration through the SAT portal del contribuyente by the 17th calendar day of the month following the taxable period.

The IVA is an indirect consumption tax levied at multiple stages of the production and distribution chain. Under Article 1 LIVA, the general IVA rate is 16% on the value of goods sold (enajenación de bienes), services rendered (prestación de servicios), leases granted (arrendamiento), and temporary imports (importaciones temporales) by individuals and legal entities carrying out commercial activities in Mexican territory. Certain goods and services are subject to the 0% rate (tasa cero) under Articles 2-A through 4 LIVA — these include basic food items (alimentos en su estado natural), agricultural and livestock products, medicines, non-luxury books and magazines, and exports — allowing input IVA recovery without output IVA obligation. Activities exempted from IVA under Articles 9, 15, 19, and 25 LIVA — such as residential property sales, credit and financial services, contributions to non-profit organisations, and most healthcare services — generate no output IVA and generally restrict input IVA crediting.

Article 31 of the Código Fiscal de la Federación (CFF), published in the DOF on 31 December 1981 and periodically reformed, establishes the general obligation for all taxpayers to submit tax declarations, payments, notifications, and requests electronically through the official SAT systems using the taxpayer's RFC and e.firma (electronic signature) or CIEC (Contraseña). The monthly IVA declaration must be submitted through the SAT's Declaraciones y Pagos (DyP) platform, which replaced the former MULTI-IVA system. The DyP platform pre-populates the declaration with data extracted from CFDI (Comprobantes Fiscales Digitales por Internet) issued and received by the taxpayer, providing a provisional calculation the taxpayer must verify and confirm before submission.

The Servicio de Administración Tributaria (SAT) is the federal tax authority responsible for administering IVA compliance under the Ley del SAT published in the DOF on 15 December 1995. The SAT operates a sophisticated cross-validation system matching taxpayer-reported IVA figures against the CFDI database — every invoice issued in Mexico must be stamped (timbrada) through a Proveedor Autorizado de Certificación (PAC) and the data transmitted to the SAT in real time, creating a comprehensive audit trail. Discrepancies between declared IVA and CFDI-derived data generate automatic SAT notifications (buzonazos) and may trigger formal audits (revisiones de gabinete or visitas domiciliarias) under Articles 42 through 67 CFF.

The LIVA also imposes specific IVA obligations for cross-border digital services provided by foreign platforms to Mexican users. Under Articles 18-B through 18-J LIVA (added by the 2020 digital economy reform), foreign suppliers of digital services — streaming platforms, online marketplaces, software-as-a-service providers — must register with the SAT, collect 16% IVA from Mexican consumers, and remit it monthly. Mexican businesses receiving digital services from abroad without local IVA collection must self-assess and remit IVA under the reverse-charge mechanism (retención) under Article 1-A-Bis LIVA. The IVA on importation of tangible goods is handled through the customs declaration (pedimento) submitted to the Agencia Nacional de Aduanas de México (ANAM) under Articles 24 through 28 LIVA.

A Monthly IVA Return Mexico is required every calendar month by any individual (persona física) or legal entity (persona moral) registered in Mexico's taxpayer registry (RFC) under an economic activity that generates IVA obligations — whether output IVA at the general 16% rate, the 0% rate on basic goods and exports, or carries creditable input IVA from acquisitions used in taxable activities. Article 5-D LIVA requires monthly filing even when no IVA is payable — a zero-balance declaration (declaración en ceros) must be submitted to confirm that no taxable activities occurred during the period.

The return is required by the 17th calendar day of the month following the taxable period. For example, the IVA declaration for the month of March must be submitted by 17 April. If the 17th falls on a non-business day (Saturday, Sunday, or official holiday as listed under Article 12 CFF), the deadline shifts to the next business day. Taxpayers registered under the Régimen Simplificado de Confianza (RESICO) for physical persons under Article 113-E LISR are subject to modified IVA reporting rules under the LIVA, filing through the RESICO platform rather than the standard DyP system.

The monthly IVA return is needed when a taxpayer must report: (a) output IVA (IVA causado) on invoices (CFDI) issued during the month for goods sold, services rendered, or leases granted at 16%; (b) input IVA (IVA acreditable) on CFDI received during the month for purchases, expenses, and services used in taxable activities, satisfying the Article 5 LIVA crediting requirements; (c) IVA withheld (IVA retenido) on payments to third parties subject to mandatory withholding — services from individuals (personas físicas), transportation services, commission agents, and certain professional services — under Article 1-A LIVA; and (d) IVA on imports processed through pedimentos during the month.

The return is also required when a taxpayer carries a creditable IVA balance (saldo a favor) from a prior month — the balance may be applied against the current month's output IVA, carried forward to subsequent months, or the taxpayer may request a cash refund (devolución) through the SAT portal under Article 22 CFF. Exporters who generate consistently zero-rated output IVA but incur input IVA on domestic purchases use the monthly return to accumulate and eventually request refund of their input IVA credit. The SAT processes refund requests within 40 business days under Article 22 CFF, provided the taxpayer's CFDI records and electronic accounting (contabilidad electrónica under Article 28 CFF) are consistent.

A complete Monthly IVA Return Mexico under Article 5-D LIVA must accurately capture the following components to produce a legally compliant declaration submitted through the SAT's Declaraciones y Pagos platform.

Taxpayer Identification: The taxpayer's RFC, legal name or fiscal name, and tax regime (régimen fiscal) registered with the SAT. The RFC must match the e.firma (FIEL — Firma Electrónica Avanzada) used to authenticate the declaration. Entities with multiple establishments (sucursales) report consolidated IVA across all locations in a single RFC-level declaration.

Output IVA at 16% Rate (IVA Causado Tasa 16%): Total value of taxable activities (actos o actividades gravados) at the general 16% rate — goods sold, services rendered at market value, and lease payments received during the month. The taxable base is the precio o contraprestación agreed in each transaction per Article 12 LIVA, excluding IVA itself. Discounts, rebates, and returned goods (devoluciones) reduce the taxable base under Article 7 LIVA. Each transaction must be supported by a stamped CFDI issued through a PAC (Proveedor Autorizado de Certificación), as the SAT cross-references all declared figures against its CFDI database.

Output IVA at 0% Rate (IVA Tasa 0%): Total value of activities taxed at zero rate under Article 2-A LIVA — exports of goods and services, basic food sales, medicines, and other specified activities. Zero-rate activities do not generate IVA payable but maintain the taxpayer's right to credit input IVA under Article 4 LIVA. The SAT monitors the proportion of 0% activities to verify the legitimacy of export claims, requiring supporting documentation such as customs pedimentos, export CFDI, and foreign client invoices.

Creditable Input IVA (IVA Acreditable): Total IVA paid or charged on acquisitions, expenses, imports, and services received and used strictly in taxable activities during the month. Article 5 LIVA establishes four requisites for IVA creditability: the expense must be deductible for ISR purposes; the IVA must be expressly stated on a duly issued CFDI; the CFDI must have been effectively paid using banking means (pagos con medios electrónicos) for transactions above $2,000 MXN; and the input IVA must correspond to activities generating output IVA or zero-rated IVA. Input IVA attributable to exempt activities is not creditable. Where a taxpayer performs both taxable and exempt activities, a proration formula under Article 5-C LIVA applies.

IVA Withheld and Retained (IVA Retenido): Where the taxpayer made payments to persons subject to mandatory IVA withholding under Article 1-A LIVA — services from individuals (personas físicas), transportation services, and certain professional fees — the amount withheld must be reported separately. The withheld IVA is paid by the withholding agent (retenedor) directly to the SAT on behalf of the service provider, separate from the taxpayer's own output IVA.

Net Monthly IVA Balance: The final calculation — output IVA at 16% plus output IVA at 0% (zero), minus creditable input IVA, adjusted for IVA withheld and prior-period credits — produces either a net amount payable to the SAT (IVA a cargo) or a credit balance in favour of the taxpayer (saldo a favor). Payment must accompany the declaration through the SAT portal using interoperability with the banking system (complemento de pago through the SAT DyP platform), generating a payment line (línea de captura) or via direct bank transfer to the SAT's designated Clabe Interbancaria.

Electronic Accounting Integration: Under Article 28 Section IV CFF and the SAT's electronic accounting rules (Contabilidad Electrónica), taxpayers must maintain their accounting in electronic format and submit monthly trial balances (balanza de comprobación) and quarterly transaction catalogs through the SAT portal. IVA declaration figures must reconcile with the corresponding accounting entries in the Catálogo de Cuentas SAT-compliant chart of accounts.

Forms-legal.com provides this Monthly IVA Return template as an administrative reference tool for Mexican taxpayers managing VAT compliance. All IVA calculations and declarations must be prepared or reviewed by a Contador Público Certificado (CPC) registered with the Instituto Mexicano de Contadores Públicos (IMCP) and must be filed electronically through the official SAT Declaraciones y Pagos platform. Incorrect IVA declarations expose taxpayers to surcharges, fines under Articles 76 through 80 CFF, and potential criminal liability for tax fraud under the Código Fiscal de la Federación when deliberate underreporting is detected.
