You don’t have to work or own a business in Mexico to need an RFC.
Mexico’s tax identification number comes up in more places than you might expect. Depending on your situation, you may need one for tax matters, official invoices, banking, or real estate transactions.
So what exactly is an RFC, who can get one, and how do you apply?
What is an RFC?
RFC stands for Registro Federal de Contribuyentes. It is a unique tax registration number administered by Mexico’s tax authority, the Servicio de Administración Tributaria (SAT).
For individuals, the relevant category is Persona Física, or individual taxpayer. Businesses and other legal entities register as Persona Moral.
Who can get an RFC and do residents really need one?
Temporary and Permanent Residents can obtain an RFC. Having an RFC does not necessarily mean you work in Mexico or run a business here.
Even if you don’t work in Mexico, an RFC may still be required for certain financial, tax, and real estate matters.
What is an RFC used for?
The RFC identifies individuals and businesses within Mexico’s tax system.
Employers use RFC information for payroll and tax reporting, while business owners and self-employed individuals use it when reporting income and expenses.
It is also used for Mexico’s electronic tax invoices, or facturas, and can come into play during real estate and other financial transactions.
What’s the difference between a CURP and an RFC?
Your CURP (Clave Única de Registro de Población) is an 18-character identification code used within Mexico’s government systems. Foreigners with Temporary or Permanent Residency are assigned a CURP through the residency process.
Your RFC identifies you within Mexico’s tax system and requires a separate registration with SAT.

What is a factura, and why does my RFC matter?
A factura is an official electronic tax invoice. Unlike a standard receipt, it can be used to formally document an expense for tax purposes.
When you request a factura, the seller will ask for your RFC. Facturas are issued electronically through Mexico’s tax system.
Why is an RFC important if I own property in Mexico?
An RFC can become important when you sell property in Mexico. SAT states that if you receive income from selling real estate and aren’t already registered with the RFC, you must register.
What are the steps to register for an RFC?
For Temporary and Permanent Residents, the process generally looks like this:
Make sure you have your CURP. Temporary and Permanent Residents are assigned a CURP through the residency process.
Gather your documents. Check SAT’s current requirements before your appointment. These include your immigration document, proof of address, and valid identification.
Book an appointment with SAT. RFC registration is completed in person at a SAT office.
Complete your registration. Bring the required documents to your appointment and complete the process with SAT.
Keep your RFC documents. Once registered, SAT provides an Acuse Único de Inscripción, which includes your Cédula de Identificación Fiscal, Guía de Obligaciones, and QR code.
Registration is free.
You can complete the process yourself. If you’d rather have help with the paperwork or SAT appointment, you can also use a local professional familiar with the process.
