Yet despite how common the requirement is, many people remain uncertain about exactly who must file, what documents are needed, and how to navigate FBR's IRIS portal correctly and confidently.
Filing your income tax return isn't just a legal requirement — it's also how you become an active taxpayer, unlocking lower withholding tax rates on countless transactions, from property purchases to banking services. Non-filers, by contrast, face significantly higher rates across the board, making timely, accurate filing a financially smart decision, not just a compliance checkbox.
