If you’re an entrepreneur planning to do business in Mexico, obtaining your RFC number (Registro Federal de Contribuyentes) is your first critical step. The RFC is the Mexican tax ID issued by the Servicio de Administración Tributaria (SAT) and is mandatory for any individual or legal entity engaging in economic activity in Mexico. It’s more than just a tax number—it’s your legal identity before Mexican authorities.
What Is the Mexican RFC number or identification number?
The RFC is a unique alphanumeric code required to pay taxes, issue invoices, hire employees, and open a business bank account in Mexico. It applies to both individuals and companies. Foreign-owned businesses must also secure their RFC as part of the incorporation and operational process. Without an RFC, you cannot legally generate income in Mexico.
Tax Regimes for Mexican companies
Upon obtaining your RFC, SAT will assign your business to a specific tax regime depending on your entity type and activity. The most common business tax regimes include:
-
Régimen General de Ley de Personas Morales – for corporations (S.A. de C.V., S. de R.L., etc.)
-
Régimen de Incorporación Fiscal (RIF) – for micro/small businesses (now replaced by RESICO in most cases)
-
Régimen Simplificado de Confianza (RESICO) – simplified trust regime with low rates for compliant entities
-
Régimen de Actividades Empresariales y Profesionales – for individuals with business income
Damalion ensures your company is placed in the correct regime from day one, to avoid penalties or unnecessary tax burdens.
Key Rights and Restrictions with an RFC
With an RFC, your company gains the right to issue official digital invoices (CFDI), register employees with the social security system, and access formal banking and credit facilities in Mexico.
However, RFC holders must also comply with:
-
Monthly and annual tax declarations
-
Use of authorized e-invoicing platforms
-
Electronic accounting submissions to SAT
-
Strict deadlines for compliance reporting
There are no shortcuts—but with expert guidance, compliance becomes manageable and safe.
Legal and Tax Obligations
Once registered, your business has several obligations:
-
Maintain an active fiscal address for tax and legal notices
-
Activate and manage your e.Firma (digital signature) for all interactions with SAT
-
Issue compliant CFDI invoices for every transaction
-
Appoint a legal representative if owners reside outside Mexico
-
Keep accounting records and submit them electronically (if applicable)
-
File monthly and annual tax returns
Damalion’s all-inclusive package handles every one of these for you—giving you peace of mind while focusing on growth.
