SAT Change of Fiscal Domicile Notice Mexico (Aviso de Cambio de Domicilio Fiscal)

A SAT Change of Fiscal Domicile Notice Mexico (Aviso de Cambio de Domicilio Fiscal) is a formal notification filed by a taxpayer — either a persona física (natural person) or persona moral (legal entity) — with the Servicio de Administración Tributaria (SAT) to update the domicilio fiscal (fiscal domicile/registered tax address) associated with their Registro Federal de Contribuyentes (RFC), as required by Article 27 of the Código Fiscal de la Federación (CFF) — Artículo 27 CFF — and the complementary Reglas Misceláneas Fiscales (RMF) issued annually by the SAT.

The domicilio fiscal is the official address recorded in the Registro Federal de Contribuyentes that serves as the legal address for all fiscal purposes: it is the address to which the SAT directs notifications (notificaciones), audit orders (órdenes de visita domiciliaria), fiscal credit determinations (créditos fiscales), and procedimientos administrativos de ejecución (PAE — tax enforcement proceedings). Under Artículo 10 CFF, the domicilio fiscal for personas morales is the address where the principal place of administration (administración principal del negocio) or the place where the principal activity is carried out (lugar donde se realice la actividad principal) is located. For personas físicas engaged in business activities, the domicilio fiscal is the address of their establishment or the place where the records are kept.

The SAT administers the RFC through the Registro de Contribuyentes system, and all modifications to a taxpayer's RFC data — including the domicilio fiscal — must be performed through the Portal del SAT (sat.gob.mx) using the taxpayer's e.firma (electronic signature certificate and private key issued by the SAT) or CIEC (Contraseña — SAT password), or in person at a SAT Module (Módulo de Servicios Tributarios). The Reglas Misceláneas Fiscales, specifically Rule 2.5.10 of the RMF 2024 and equivalent prior-year rules, govern the procedure for filing the Aviso de Cambio de Domicilio Fiscal electronically.

The obligation to notify the SAT of a domicile change is distinct from the obligation to update address information with other government agencies and registries. A change in the principal place of business of a persona moral may also require: an update to the Registro Público de Comercio through a protocolised Asamblea de Accionistas or amendment to the Estatutos Sociales authorised before a Notario Público; notification to the Instituto Mexicano del Seguro Social (IMSS) of the change in the patron's domicilio (Artículo 15 LSS); notification to the INFONAVIT; and updating the addresses in commercial licences (licencias de funcionamiento) issued by the Municipio or Alcaldía where the business operates under state and municipal regulations.

The Aviso de Cambio de Domicilio Fiscal has particular importance in tax enforcement: the SAT uses the registered domicilio fiscal as the address for all official notifications. Under Article 134 of the CFF (Artículo 134 CFF), personal notification at the domicilio fiscal is one of the primary methods for serving tax acts — including audit initiation notices, assessment determinations, and enforcement orders. A taxpayer who fails to update their domicilio fiscal and consequently does not receive official SAT notifications loses the ability to challenge those acts within the applicable legal timeframes under Article 121 of the CFF (Artículo 121 CFF — Recurso de Revocación, 30-day challenge period) and Artículo 13 of the Ley Federal de Procedimiento Contencioso Administrativo (LFPCA — 30-day Tribunal Federal de Justicia Administrativa petition period).

Mexico's comprehensive tax reform (reforma fiscal) has increasingly required that the domicilio fiscal be a verifiable, physical address where the taxpayer can be located — the SAT conducts domicilio fiscal verification visits (verificaciones de domicilio) and may restrict or cancel the RFC of taxpayers whose registered address cannot be confirmed through inspection.

An Aviso de Cambio de Domicilio Fiscal Mexico is required within 10 business days whenever a taxpayer's principal place of business, administration, or tax-relevant activity moves to a new address, under Artículo 27 CFF and Rule 2.5.10 of the Resolución Miscelánea Fiscal.

For personas morales, the aviso is needed when: the company's registered office (domicilio social) and principal place of administration relocates to a new building, floor, or municipality; the company moves its head office between states (for example, from Ciudad de México to Guadalajara, Jalisco), which may also affect the competent SAT regional administration (Administración Desconcentrada de Auditoría Fiscal); the manufacturing plant or principal commercial establishment that constitutes the domicilio fiscal under Artículo 10 CFF moves to a new address; or the lease agreement for the current registered office expires and the company moves to new premises.

For personas físicas with actividades empresariales y profesionales (business and professional income under Chapter II of Title IV of the Ley del Impuesto sobre la Renta — LISR), the aviso is needed when the home office, consulting office, retail store, or other business establishment changes address. Personas físicas who perform only wage income (ingresos por salarios) do not have a formal domicilio fiscal obligation in the same sense — their employer's address serves as the primary contact point — but they may still update their RFC address for correspondence purposes.

The Aviso de Cambio de Domicilio Fiscal is also needed when a previously registered domicilio fiscal is determined to be invalid — for example, when the SAT conducted a verification visit and could not find the taxpayer at the registered address, resulting in an RFC restriction (restricción temporal del uso del RFC) under the 69-B CFF presumption of simulated operations (operaciones simuladas — EFOS/EDOS scheme). Correcting the domicilio fiscal is one of the steps required to lift the RFC restriction in such cases.

New foreign investment entities registering with the Registro Nacional de Inversiones Extranjeras (RNIE) administered by the Secretaría de Economía under the Ley de Inversión Extranjera (LIE) must confirm their SAT domicilio fiscal matches the address registered with RNIE, making the Aviso de Cambio de Domicilio Fiscal relevant whenever the two records diverge following an address change.

A valid Aviso de Cambio de Domicilio Fiscal Mexico under Artículo 27 CFF and the applicable RMF rules must include the following elements to complete the SAT domicile update process.

Taxpayer Identification: Full legal name or denominación social of the taxpayer, RFC (Registro Federal de Contribuyentes — 12 characters for personas morales, 13 for personas físicas), and the CURP (for natural persons). The RFC is the primary identifier linking the aviso to the taxpayer's SAT account.

Previous Domicilio Fiscal: The complete former address as registered in the SAT's RFC records, including street name and number (calle y número exterior e interior), colonia or fraccionamiento, municipio or alcaldía, state (entidad federativa), and Código Postal (CP). This allows the SAT to match the notification against the existing RFC record.

New Domicilio Fiscal: The complete new address with all address components, including the Código Postal corresponding to the new location. For businesses, the address must correspond to the actual physical location of the principal place of administration or the place where the principal commercial, industrial, or professional activity is conducted — a domicilio fiscal may not be a virtual office, PO box, or residential address used solely for mail forwarding purposes, per SAT verification criteria.

Proof of New Domicilio: Supporting documentation demonstrating that the taxpayer actually occupies and uses the new address for fiscal purposes. Accepted documents under the RMF include: a current lease agreement (contrato de arrendamiento) bearing the new address and a recent utility bill or account statement (comprobante de domicilio — electricity, water, telephone, internet) in the taxpayer's name, dated within the last three months; a property deed (escritura pública) showing ownership of the new address; or a property tax receipt (recibo de pago del predial) in the taxpayer's name for the new address. Digital proofs submitted through the Portal del SAT must meet the format specifications in Anexo 1-A of the RMF.

Date of Move: The date on which the taxpayer physically relocated to the new address — the 10-business-day filing deadline runs from this date under Artículo 27 CFF.

Buzón Tributario Update: Confirmation that the taxpayer's registered email addresses in the SAT Buzón Tributario — the mandatory electronic notification system under Artículo 17-K CFF — are current and will receive official SAT communications at the new domicilio. Because SAT notifications sent to the Buzón Tributario are legally deemed received three business days after transmission under Artículo 134 Fracción I CFF regardless of actual delivery, maintaining correct Buzón contact data alongside the physical address update is essential for preserving the taxpayer's ability to respond to audit notices, tax credit determinations (créditos fiscales), and enforcement actions (procedimientos administrativos de ejecución — PAE) within the applicable legal deadlines under Artículo 121 CFF and the Ley Federal de Procedimiento Contencioso Administrativo.

Electronic Filing or In-Person Submission: The aviso is filed electronically through the Portal del SAT (sat.gob.mx) using the taxpayer's e.firma or Contraseña, or in person at a SAT Module with valid identification. Electronic filings generate an acuse de recibo (acknowledgement receipt) with a folio number that serves as confirmation. For personas morales, filing must be performed by the legal representative (representante legal) whose power of attorney (poder notarial) is registered with the SAT, or through the SAT's authorized accounting representative (contador autorizado) where applicable.
