As the 2025 tax return filing season begins, the Federal Board of Revenue (FBR) anticipates a surge in the number of new taxpayers filing their income tax returns. In light of the latest measures introduced through the Finance Act, 2025, the FBR has issued detailed guidelines to help individuals, companies, and associations of persons (AOPs) access the IRIS portal, which is the official platform for online tax return submission.
According to FBR, registration on the IRIS portal is the first step for all new filers. This process, known as e-enrollment, ensures that taxpayers receive their National Tax Number (NTN) or Registration Number, along with a secure password. These credentials grant access to the IRIS portal, where tax returns are filed and tax-related services are managed.
For individuals, the 13-digit Computerized National Identity Card (CNIC) number automatically serves as the NTN or Registration Number. For AOPs and companies, a 7-digit NTN is issued upon completion of the e-enrollment process.
Once registered, users can log into the IRIS portal using their NTN/CNIC and password. This portal is the only official digital platform provided by the FBR for filing income tax returns, checking filing status, and managing tax obligations.
The FBR encourages all new filers to begin the registration process early to avoid last-minute delays. User-friendly tutorials and help guides are also available on the portal to assist taxpayers in navigating the IRIS system smoothly.
