What Is a Branch Office Opening Notice Mexico (Aviso de Apertura de Sucursal)?

A Branch Office Opening Notice Mexico (Aviso de Apertura de Sucursal) is a formal written notification submitted by an existing Mexican or foreign company (sociedad mercantil) to multiple regulatory authorities — principally the Servicio de Administración Tributaria (SAT), the Instituto Mexicano del Seguro Social (IMSS), and the municipal licensing authority — when establishing a new branch office (sucursal), secondary location (establecimiento secundario), agency (agencia), or satellite office (oficina satélite) distinct from the company's registered domicile (domicilio social) or principal establishment (establecimiento principal). The Branch Office Opening Notice triggers a series of registration, fiscal, and labour compliance obligations distinct from the original company registration, reflecting the fact that a sucursal is a legally dependent but operationally separate unit of the parent company (empresa matriz).

The Código de Comercio Article 21 Fraction IV requires that the establishment of branches (sucursales) of a commercial company be recorded in the Registro Público de Comercio (RPC) — each sucursal must be inscribed at the RPC of the state where it operates, with a certified copy of the corporate resolution (acuerdo del consejo de administración or asamblea de socios) authorising the sucursal's establishment. This registration establishes the sucursal's legal existence for commercial notice purposes and ensures that third parties can verify the sucursal's authorisation to act on behalf of the parent company.

The Código Fiscal de la Federación Article 27 and the Reglamento del CFF Article 29 Fraction VII require taxpayers to notify SAT of the establishment of new business locations (establecimientos) within their RFC registration. For each new sucursal, the parent company must update its RFC domicile data (datos del registro) to add the sucursal address as a secondary fiscal location (domicilio secundario or sucursal registrada) — this confirms that SAT's audit and inspection records reflect all physical locations where the company operates. The Resolución Miscelánea Fiscal 2025 provides the specific SAT Ficha de Trámite applicable to sucursal registrations.

For labour law purposes, each sucursal that employs workers (trabajadores) must be registered as a separate work centre (centro de trabajo) with the Inspección Federal del Trabajo under the Ley Federal del Trabajo and must independently comply with LFT obligations including reglamento interior de trabajo, comisiones mixtas de seguridad e higiene, and profit-sharing (PTU) calculations based on the sucursal's workforce. The IMSS employer registration must be expanded to include the new sucursal as a subsidiary work centre (subdelegación IMSS) — each sucursal may require a separate IMSS work centre number (número de registro de obra or sucursal) depending on the IMSS subdelegación jurisdiction.

For foreign companies establishing a sucursal in Mexico (rather than incorporating a Mexican subsidiary), the Ley de Inversión Extranjera (LIE) and the Ley General de Sociedades Mercantiles (LGSM) Article 250 apply — a foreign company's Mexican branch must register with the Secretaría de Economía through the Dirección General de Inversión Extranjera and comply with the RFC registration, SAT fiscal obligations, and municipal licensing requirements applicable to all Mexican business establishments. The foreign branch (sucursal de empresa extranjera) is treated as a permanent establishment (establecimiento permanente) for ISR purposes under CFF Article 9 and LISR Articles 2 and 3, subject to Mexican income tax on Mexico-source income.

From a practical perspective, the sucursal structure differs from incorporating a new subsidiary (filial) — a sucursal is not a separate legal entity, does not have its own RFC (it operates under the parent company's RFC with a secondary location designation), and its obligations and liabilities are legally attributed to the parent company. This contrasts with a subsidiary (empresa subsidiaria), which is an independent legal entity with its own RFC, its own directors, and its own separate legal liability — though it may be wholly owned by the parent company.

When Do You Need a Branch Office Opening Notice Mexico (Aviso de Apertura de Sucursal)?

A Branch Office Opening Notice Mexico is required whenever an existing company opens an additional business location (sucursal, agencia, or oficina) distinct from its registered domicile — whether in the same city or a different state — to comply with CFF Article 27 SAT notification, Código de Comercio Article 21 Fraction IV RPC registration, and municipal licensing requirements.

The notice is needed when a retail chain (cadena de tiendas), restaurant group, bank, insurance company, or service company opens a new physical location. Each new location constitutes a sucursal requiring SAT RFC domicile update, municipal licencia de funcionamiento, and IMSS work centre registration for the new location's employees. Companies with multiple sucursales across Mexico — such as OXXO (Grupo FEMSA), Soriana, Liverpool, Chedraui, or national restaurant chains — must maintain current regulatory registrations for each location.

The document is required when a foreign company establishes its first or additional physical office, warehouse, or distribution centre in Mexico. Under Ley de Inversión Extranjera and LGSM Article 250, the foreign company's Mexican presence constitutes a sucursal de empresa extranjera requiring Secretaría de Economía registration, SAT RFC registration as a Mexican establishment, and all applicable municipal and IMSS registrations.

The notice is necessary when a company opens a sucursal in a different Mexican state than its registered domicile — triggering RPC registration in the new state, potential state tax obligations (impuesto sobre nómina — ISN — varies by state from 1% to 3% of payroll), and compliance with the applicable state's municipal licensing requirements that differ from the home state.

Under CFF art. 27, Código de Comercio art. 21 Frac. IV, and LSS arts. 12–20, any company that opens a new physical business location in Mexico where commercial activities or workers are present must file the applicable branch opening notices before operations begin — failure to register the sucursal with SAT, IMSS, and the municipal authority creates fiscal compliance gaps, CFDI invalidity risks for the sucursal, and labour law violations.

What to Include in Your Branch Office Opening Notice Mexico (Aviso de Apertura de Sucursal)

A valid Branch Office Opening Notice Mexico must contain the following elements to satisfy the requirements of SAT, IMSS, the Registro Público de Comercio, and the municipal licensing authority:

Parent Company Identification: Full legal name (denominación social), RFC (with homoclave), IMSS employer registration number (número de registro patronal), Registro Público de Comercio folio number, and registered domicile (domicilio social) of the parent company (empresa matriz). The RFC is the primary identifier linking all branch locations to the parent company's tax account.

Branch Office Details: Full physical address of the sucursal — street, building number, interior designation, colonia, municipio or alcaldía, state, and código postal. The SCIAN economic activity code applicable to the sucursal's operations. Commercial name (nombre comercial) of the sucursal if different from the parent company's name. Estimated number of workers (trabajadores) to be employed at the sucursal.

Corporate Authorization: Reference to the corporate resolution (acuerdo del consejo de administración, asamblea de accionistas, or asamblea de socios) authorising the establishment of the sucursal — including the date of the resolution, the notarial deed number (número de escritura), and the Notario Público before whom the resolution was formalised. For SAT and RPC purposes, a certified copy of this resolution is a required supporting document.

Designated Branch Manager or Representative: Name, RFC, CURP, and official identity document of the sucursal manager (gerente de sucursal) or local representative (representante local) authorised to act on behalf of the parent company at the sucursal level — including the scope of their authority (whether they hold a separate power of attorney for the sucursal or act under the parent company's corporate representative authority).

SAT Secondary Location Registration: Confirmation that the sucursal address is being added as a secondary domicile (sucursal registrada) in the parent company's RFC record through the SAT Portal — the SAT update must reference the Ficha de Trámite for domicilio secundario registration. SAT Circular and Resolución Miscelánea Fiscal specify the documents required for secondary location registration.

IMSS Work Centre Registration: Reference to the IMSS work centre (alta de centro de trabajo) notification submitted at the applicable IMSS Subdelegación for the sucursal — required within 5 business days of the first employee being hired at the sucursal. The IMSS work centre registration may result in a new registro patronal number for the sucursal or an extension of the parent company's existing registro patronal depending on IMSS subdelegación jurisdiction.
