How to get an RFC

by San Miguel MLS on October 1, 2024

To get an RFC (Registro Federal de Contribuyentes) number in Mexico, follow these steps. The RFC is the tax identification number used by Mexico’s Servicio de Administración Tributaria (SAT), similar to a social security number for tax purposes. Here’s how you can apply for one:

1. Determine if You Need an RFC

• Foreigners typically need an RFC if they are working in Mexico, starting a business, buying property, or generating any form of income within the country.
• If you’re a foreigner living in Mexico and don’t have a CURP (Mexican identification number), you’ll first need to obtain one before applying for the RFC.

2. Documents Required for RFC Registration

Before heading to the tax office or starting the online process, make sure you have the following documents ready:

• Valid passport or government-issued ID.
• Temporary or Permanent Resident Card (if applicable).
• Proof of address in Mexico (such as a utility bill, bank statement, or rental agreement).
• CURP (Clave Única de Registro de Población). Foreigners need this as part of their registration; it’s like the Mexican social security number. You can get your CURP at the National Migration Institute (INM) or online.
• Completed registration form from the SAT (this can be done online or in person).

3. Register Online or In-Person

There are two main ways to obtain an RFC: online through the SAT’s website or in-person at a local SAT office.

Option 1: Online Registration

If you have a CURP and Mexican residency, you can follow these steps:

• Go to the SAT website: www.sat.gob.mx
• Find the “RFC” section for “Personas Físicas” (individuals).
• Complete the online form with your personal details, including CURP.
• Follow the instructions to generate your RFC online.
• Once completed, you will receive your RFC immediately with a printable confirmation.

Note: Online registration might not be available to foreigners in all cases, and you may be required to visit an office for verification.

Option 2: In-Person Registration

For those who prefer an in-person process or if you’re unable to register online:

• Make an appointment at your local SAT office (appointments can be made through the SAT website).
• Bring all required documents, including copies.
• The SAT office will assist you in filling out any necessary forms and processing your RFC.
• After verification of your documents, you’ll receive your RFC number immediately.

4. Get Your e.firma (Optional)

As part of the process, you may also want to apply for your e.firma (formerly known as FIEL). This is an electronic signature used for signing digital documents securely. It’s not mandatory for every individual, but if you plan to engage in business, work with the government, or file taxes online, having an e.firma is highly recommended.

5. Ensure You Stay Compliant

Once you have your RFC, remember that it ties you to Mexico’s tax system. Even if you’re not earning income in Mexico, you must keep your registration information up to date. You should file tax returns or declare that you have no taxes to pay if applicable. It’s always a good idea to consult with a tax advisor who understands both your home country’s tax laws and Mexico’s tax regulations, particularly if you’re a foreigner.

Tips for Foreigners

• No CURP?: If you don’t have a CURP yet, you’ll need to go through the process of getting one first before applying for the RFC. A CURP can be obtained through the Instituto Nacional de Migración (INM) or Mexican embassies.
• Get Professional Help: If you’re unsure about the process or have complex circumstances, it’s wise to get assistance from a tax expert or legal advisor who can guide you through the registration.

Conclusion

Getting an RFC is essential if you plan to engage in financial transactions in Mexico, whether for work, business, or property investments. It is relatively straightforward if you have the required documents and follow the correct process, but make sure you’re aware of the tax responsibilities that come with it.
