Simply put, a RFC is your tax ID, and allows you to engage in economic activity in Mexico and for you to pay income taxes. With a RFC you can also issue and receive facturas. It is important when you are filing taxes in Mexico to obtain as many facturas as possible. Collecting facturas will help to offset the amount of taxes you have to pay to SAT. You must be a legal resident of Mexico to obtain a RFC. A RFC is not required to purchase or sell property in Mexico, there are provisions in the law that allow foreigners acquire and sell real estate without it. For more information on RFCs, please click
