How to File Income Tax Return Online – IRIS Portal
Annual filing via IRIS follows specific steps. Here is the complete walkthrough.
Filing your annual income tax return through Federal Board of Revenue's (FBR) IRIS portal is the standard procedure for Pakistani taxpayers — salaried individuals, business owners, freelancers, professionals, and anyone earning above the basic exemption threshold. The IRIS (Integrated Revenue Information System) portal handles registration, return preparation, submission, payment integration, and post-submission tracking. The process can feel daunting first time but follows specific steps that become routine after one or two filing cycles. This guide focuses on the filing procedure itself — what happens in IRIS, how to prepare, and what to expect through submission. Specific scenarios (freelancer, salaried, business owner) have related guides covering category-specific considerations.
What to prepare before filing

- NTN or CNIC — National Tax Number or CNIC for identification within IRIS. CNIC works for individuals; NTN required for some categories.

- Income documentation — salary slips (monthly), bank statements, business P&L if applicable, rental income records, foreign income documentation.
- Tax deducted evidence — salary tax withholding certificates from employer (Form 16), bank withholding on various income types, vehicle/property tax withholding records.

- Business tax filers — specific deadlines for audited business returns (typically December following).
- Late filing — penalties apply. Loss of filer status benefits until subsequent compliance.
- Filer status from filing — current year's filing supports next year's filer status on ATL list.

- Continuous process — annual filing is regular obligation. Plan to maintain filer status year after year.
- Don't wait until deadline — IRIS system may have heavy load near deadline. File earlier when possible.

IRIS tax filing — common questions
Closing note on filing as ongoing obligation
Tax filing in Pakistan has become more accessible through IRIS — the system that handled complex paperwork decades ago now operates online with specific guides and documentation. Annual filing becomes routine after first experience.
The benefits of timely compliance — filer status, lower transaction taxes, formal documentation of income — justify the modest annual effort. Late filing creates specific issues beyond just penalties. Pakistani consumers and businesses benefit from consistent filing year after year.
Filing procedures, IRIS specifics, and Pakistani tax framework described above reflect current policy as of early 2026. Specific tax policies, rates, and deadlines evolve — verify current state through FBR sources for actual filing.
