How Do I Obtain an RFC Tax Number in Mexico?

An RFC (Registro Federal de Contribuyentes) is Mexico’s official tax ID, required for activities like buying or selling property, opening certain bank accounts, or registering as a taxpayer.

How to get it:

• Online:You can apply through Mexico’s tax authority (SAT) website if you meet the requirements.

• In person:Visit a local SAT office (for example, in Puerto Vallarta). This is often the fastest option, especially for real estate transactions.

What you’ll need:

• Valid passport

• Immigration card (temporary or permanent resident)

• Proof of address (Mexico or abroad)

If you don’t already have an RFC, a generic foreigner RFC can be issued for the property closing. Many buyers later upgrade it to a full RFC once registered with SAT.

Getting your RFC in advance helps keep the closing process smooth and avoids delays.
