What is an RFC?

RFC (Registro Federal de Contribuyentes)

RFC: /EH-reh-SEH/

Registro Federal de Contribuyentes: /reh-HEES-troh feh-deh-RAHL deh kohn-tree-boo-YEN-tehs/

Quick Definition: RFC (Registro Federal de Contribuyentes) is Mexico's federal tax identification number, similar to a Social Security Number in the US or Social Insurance Number in Canada. It is required for all significant financial transactions in Mexico, including property purchases, and serves as your unique identifier within the Mexican tax system.

Your Key to Mexican Property Transactions


The RFC is a fundamental requirement for any foreign national purchasing property in Mexico. This 12-13 character alphanumeric code serves as your official identification within Mexico's tax system and is essential for legal property ownership, tax compliance, and various financial transactions. The Mexican tax authority (SAT - Servicio de Administración Tributaria) assigns each RFC uniquely to individuals and entities conducting business or owning assets in Mexico.

For property transactions, the RFC serves multiple purposes: it identifies you as the legal buyer, ensures proper tax reporting, enables the notario público to process your transaction, and establishes your status within the Mexican tax system. Without an RFC, you cannot legally complete a property purchase in Mexico, making it the first essential step in your real estate journey.

Common RFC Challenges for International Buyers


International buyers sometimes encounter specific challenges during the RFC process:

Address Verification Issues

Some buyers struggle to provide acceptable Mexican address proof, especially if staying in short-term accommodations.

Address Solutions

  • Use hotel registration as temporary address
  • Ask real estate agent to provide address letter
  • Use Airbnb confirmation with host contact information

Name Format Differences

Foreign names may not fit standard RFC formatting, especially those with multiple surnames or special characters.

Name Resolution

  • Bring multiple identification documents showing name variations
  • Consider how you want your name to appear on Mexican documents

Frequently Asked Questions


How much does it cost to get an RFC?

The RFC application is free of charge from SAT offices. However, you may incur costs for document translations ($100-300) or transportation to SAT offices. Some service providers offer RFC assistance for fees, but this is not necessary as the process is straightforward.

Can I apply for an RFC before visiting Mexico?

No, you must apply for an RFC in person at a Mexican SAT office. However, you can prepare all documents in advance and complete the application quickly once you arrive. Some buyers obtain their RFC during their first property viewing trip.

What happens if I lose my RFC information?

You can recover your RFC information online through the SAT website using your personal details, or visit any SAT office with identification. Your RFC number never changes, so once you have it, you can always retrieve the information.

Do I need to file Mexican tax returns just for owning property?

Most foreign property owners who use their homes personally and don't generate rental income above 400,000 pesos annually have minimal tax filing requirements. However, you should consult with a Mexican tax professional about your specific situation.
