RFC Basics and What It’s For
It’s a special code from the SAT for taxes in Mexico, like a number for jobs, banks, and buying stuff.
Since 2022, everyone over 18 in Mexico must have one, even without a job, to keep track of money safely.
CURP is your basic ID for life things like school, while RFC is for taxes and money matters.
No, only people living in Mexico legally, like residents, can get one—tourists don’t qualify.
Yes, it’s free through the SAT, but you might pay for help if you hire someone to guide you.
Getting Your RFC Step by Step
Go to the SAT website, make an online appointment with your CURP, and pick a nearby office.
Bring your passport, residency card, a utility bill, printed CURP, and maybe a thumb drive.
The appointment is quick, often 10-15 minutes, but wait for your slot through the virtual line.
Mostly no, you need an in-person visit, but some steps like booking are online now.
Log into the SAT site with your CURP to print your Tax Status Certificate anytime.
