How to correct or update your RFC details

Changing details in a calculator does not change your tax registration. Corrections must be made through the authority.

Identify the detail that needs correction

Compare your documents with the name, address and other tax details shown on your certificate. Distinguish an identity error from an update to your activity or address.

Choose the appropriate procedure

Use the SAT portal to find the service for your particular correction or update. Requirements and documents may differ. Do not assume that an address update also corrects a name or CURP.

Check the outcome

Keep the acknowledgement issued by SAT and check your updated certificate. If a discrepancy remains, request help through official channels.
