Step-by-Step Registration Process
Step 1: Log in to Iris Portal
Visit iris.fbr.gov.pk and log in using your NTN and password. If you do not have an NTN, first register for one through the same portal.

Submit the application and note your tracking number. The FBR will verify your documents and may conduct a physical inspection of your business premises before approving registration.
