The first step before filing your Sales Tax Return is to get yourself registered with Federal Board of Revenue (FBR).
The registration with FBR provides you with a Sales Tax Registration Number (STRN) or User ID and password. These credentials allow access to efile portal, the online portal for filing Sales Tax Return.
Online Sales Tax Return can only be filed while logging into efile portal.
The Automated System for Sales Tax Registration will be effective from July 1st, 2019, allowing for registration of the person for Sales Tax through the Iris Portal .
Only those persons having active Iris Portal credentials can Register for Sales Tax.
