How to Get Your RFC for the First Time and Choose Between an Individual or Legal Entity: A Step-by-Step Guide

The Registro Federal de Contribuyentes (RFC, Federal Taxpayer Registry) is a unique identifier that the Servicio de Administración Tributaria (SAT, Tax Administration Service) issues to all individuals and legal entities in Mexico for tax identification.

This alphanumeric code is used to keep track of taxpayers and ensure they meet their tax obligations.

Without it, you would not be able to issue invoices, receive formal payments, or complete certain legal procedures.

Who Needs to Get an RFC?

If you’re wondering whether you really need an RFC, the answer is yes in the following cases:

📌 If you are a salaried employee, your employer needs it to register you with the IMSS (Mexican Social Security Institute) and withhold taxes.
📌 If you are a freelancer or entrepreneur, it is required to issue invoices and file tax returns.
📌 If you own a business or company, you will need an RFC to formally establish it and operate legally.
📌 If you want to open a bank account, some institutions may require it.

But this raises an important question: Should I register as an individual or a legal entity?

Difference Between an Individual RFC and a Legal Entity RFC

📌 RFC for Individuals

Individuals are people who engage in economic activities independently or as employees.

🔹 If you are self-employed, a freelancer, or an entrepreneur, this is the type of RFC you need.
🔹 You also need one if you are a salaried employee and your employer requires you to register with the SAT.
🔹 You can easily get one online using your CURP (Unique Population Registry Code).

📌 RFC for Legal Entities

Legal entities are companies, corporations, or associations formally registered with the SAT.

🔹 If you own a company with partners or have formed a corporation, this is the option for you.
🔹 It requires additional documentation and can only be processed at SAT offices.
🔹 It involves greater tax and accounting obligations.
