SAT Business Suspension Application Mexico (Suspensión de Actividades)

A SAT Business Suspension Application Mexico (Solicitud de Suspensión de Actividades ante el SAT) is the formal notice filed by a taxpayer — persona física (individual) or persona moral (legal entity) — with the Servicio de Administración Tributaria (SAT) to report the temporary or permanent cessation of business or professional activities, thereby suspending the obligations associated with the taxpayer's Registro Federal de Contribuyentes (RFC). Suspensión de actividades is governed primarily by Article 27 of the Código Fiscal de la Federación (CFF) and by the Resolución Miscelánea Fiscal (RMF) in force for the relevant fiscal year, which establishes the specific procedures, timelines, and supporting documentation required for a valid suspension filing.

Article 27 CFF establishes the fundamental obligation of all taxpayers to register in the RFC, keep their registry data current, and notify the SAT of changes in their tax situation — including the cessation of activities — within thirty calendar days of the triggering event. Section III of Article 27 CFF specifically contemplates the suspension of activities as a registered change that taxpayers must report through the SAT portal (sat.gob.mx) or in person at a Módulo de Servicios Tributarios. The SAT's Catálogo de Trámites (procedure catalogue) assigns specific procedure codes (RFC-related filings) to the suspensión de actividades application for both personas físicas and personas morales.

For personas físicas — including individuals registered under régimen de actividades empresariales y profesionales (REPAP), régimen de incorporación fiscal (RIF), régimen simplificado de confianza (RESICO), or arrendamiento — suspension of activities means that the taxpayer will no longer issue CFDI (Comprobante Fiscal Digital por Internet) comprobantes, file periodic declaraciones provisionales or definitivas, or make ISR (Impuesto sobre la Renta) or IVA (Impuesto al Valor Agregado) payments during the suspension period. The suspension does not extinguish prior tax obligations (obligaciones fiscales) that arose before the suspension date — the SAT retains its facultades de comprobación under Articles 42 and 46 CFF for the five-year statute of limitations period (plazo de prescripción).

For personas morales — including Sociedad Anónima de Capital Variable (S.A. de C.V.), Sociedad de Responsabilidad Limitada (S. de R.L.), Sociedad por Acciones Simplificada (SAS), and other corporate forms — suspension of activities is typically a precursor to liquidation and cancellation of the RFC under Article 26 of the Ley General de Sociedades Mercantiles (LGSM) and the subsequent deregistration procedures before the SAT. The suspensión is not available as a permanent status for personas morales that have ongoing corporate obligations — it is primarily used during the interregnum between cessation of operations and completion of the formal disolución y liquidación proceeding.

The Resolución Miscelánea Fiscal Regla 2.5.13 (and equivalent annual rules) establishes that taxpayers filing through the SAT portal must authenticate using their e.firma (electronic signature) — formerly known as FIEL (Firma Electrónica Avanzada) — or, for personas físicas with low-risk profiles, through the Contraseña (CIEC). The SAT portal generates an Acuse de Recibo (acknowledgement receipt) with a folio number upon successful filing, which constitutes the official record of the suspension for the taxpayer's files. The RFC status change from Activo to Suspendido is typically reflected in the SAT's Buzón Tributario and in the public RFC consultation tool within 2 to 5 business days of the filing.

A SAT Business Suspension Application Mexico is required — or strongly advisable — whenever a taxpayer registered in the RFC ceases generating income from the registered economic activity, whether on a temporary basis (e.g., medical leave, family emergency, seasonal business pause) or on a permanent basis (e.g., business closure, retirement, emigration).

The suspension application is needed when a persona física registered under the actividades empresariales y profesionales regime stops providing professional services or conducting commercial activities and does not anticipate generating RFC-related income for at least two consecutive months. Without filing the suspensión, the taxpayer remains obligated to file zero-income declaraciones provisionales of ISR and IVA on the 17th of each month, and failure to do so generates recargos (surcharges) and multas (fines) under Article 76 and 81 CFF — even where no actual tax liability exists. The SAT's automated system flags unfiled declarations and initiates collection procedures (procedimientos de cobro) regardless of the taxpayer's actual income level.

Personas físicas under the Régimen de Incorporación Fiscal (RIF) — being replaced by RESICO under the 2022 reform to the LISR — must file the suspension when they permanently cease low-income commercial activities, as continued registration without income triggers annual declaration obligations and loss of transitional RIF tax benefits. Under RESICO, the suspension terminates the simplified tax regime participation and stops the monthly ISR and bimonthly IVA payment obligations.

Employers who cease all payroll activities — whether sole proprietors (personas físicas with salaried employees) or empresas (personas morales) — must file the suspensión de actividades together with the baja patronal (employer deregistration) before the IMSS (Instituto Mexicano del Seguro Social) under the Ley del Seguro Social Article 15, and with the INFONAVIT (Instituto del Fondo Nacional de la Vivienda para los Trabajadores) under the corresponding INFONAVIT Ley. The CFF Article 27 filing and the IMSS baja patronal are independent procedures that must both be completed to fully terminate employer obligations.

The suspension is also required before initiating the formal cancellation of the RFC under RMF Regla 2.5.21, which requires that the taxpayer have no outstanding tax obligations (obligaciones fiscales pendientes), no pending CFDI validation, and a clean tax compliance opinion (Opinión de Cumplimiento 32-D) before the cancellation application can be processed.

A valid SAT Business Suspension Application Mexico under Article 27 of the Código Fiscal de la Federación and the applicable Resolución Miscelánea Fiscal must contain the following essential elements to be accepted by the SAT and to properly suspend the taxpayer's RFC obligations.

Taxpayer Identification: Full legal name (nombre completo or razón social for personas morales), RFC with homoclave, CURP for personas físicas, and domicilio fiscal (tax domicile) as registered in the SAT portal — matching the data in the Constancia de Situación Fiscal. Any discrepancy between the application data and the SAT registry triggers a rejection that requires a prior RFC data update filing before the suspension can proceed.

Activity Description and Cessation Date: A description of the principal economic activity (actividad económica) for which the suspension is being requested — using the SAT's own activity code from the Catálogo de Actividades Económicas (e.g., 611150 for software development, 531110 for real estate leasing) — and the specific date on which the activity was or will be ceased. The cessation date determines which monthly declarations must still be filed for the period up to and including the last month of activity.

Suspension Type (Temporal or Definitiva): The application must specify whether the suspension is temporal (temporary — anticipating resumption of activities) or definitiva (permanent — preliminary to RFC cancellation). For temporal suspensions under RMF Regla 2.5.14, the taxpayer may re-activate the RFC by filing a reanudación de actividades when commercial or professional activities resume. For definitiva suspensions, the taxpayer must subsequently file a cancellation application under RMF Regla 2.5.21 within a defined timeline.

RFC Obligations to be Suspended: The application must identify which specific tax obligations (obligaciones fiscales) will be suspended — including ISR declaraciones provisionales, IVA declaraciones definitivas, IEPS (Impuesto Especial sobre Producción y Servicios) where applicable, and retenciones (withholding declarations) for employers. Obligations arising from contracts or agreements entered before the suspension date — including ISR on deferred income (ingresos diferidos) — are not suspended by the application.

Authentication: The application must be authenticated with the taxpayer's e.firma (electronic signature certificate, formerly FIEL) or, for eligible personas físicas, with the Contraseña (CIEC). The e.firma is issued by the SAT at Módulos de Servicios Tributarios upon presentation of original RFC registration documents, CURP, identity document (INE or passport), and biometric data capture. The e.firma certificate file (.cer) and private key (.key) together with the passphrase constitute the valid authentication credential.

Opinión de Cumplimiento (32-D): While not strictly required at the suspension stage for most taxpayers, obtaining a positive Opinión de Cumplimiento Fiscal (Constancia 32-D) — confirming no outstanding tax debts — before filing the suspension is strongly recommended to avoid subsequent complications when the taxpayer seeks to cancel the RFC or participate in government procurement.

Forms-legal.com provides this SAT Business Suspension Application Mexico template as a preparation guide and information resource. All actual filings must be submitted through the SAT portal (sat.gob.mx) using the authenticated Buzón Tributario or at a Módulo de Servicios Tributarios — printed applications are not accepted by the SAT for RFC status changes. Consult a contador público certificado (CPC) or fiscal advisor registered with the Instituto Mexicano de Contadores Públicos (IMCP) before filing, particularly where prior-period tax obligations, outstanding CFDI, or employer deregistration are involved.
