Complete Guide to Filing Income Tax Returns in Pakistan (2025-26)

Every year, right around September, a familiar scramble begins across Pakistan. WhatsApp groups fill up with "does anyone know how to file taxes" messages, and tax consultants suddenly become the most popular people in every office. It doesn't have to be this stressful — filing your return for tax year 2025-26 is genuinely manageable once you understand the moving parts.

Who actually needs to file

If you're a salaried individual earning above the taxable threshold of Rs 600,000 a year, you need to file. So does anyone who owns a car above 1000cc, owns property above a certain size, has a NTN, or runs any kind of business — registered or not. In short: most working adults in Pakistan with a bank account and a salary above minimum wage should be filing.

What you'll need before you start

• Your CNIC and NTN (National Tax Number)
• Salary certificate or annual salary statement from your employer
• Bank account statements for the tax year (July to June)
• Details of any property, vehicles, or investments you own
• Withholding tax certificates from your bank, employer, or any contracts

Filing through IRIS

All returns are filed electronically through FBR's IRIS portal. If this is your first time, you'll need to register for e-enrollment first, which requires your CNIC and a working mobile number registered in your name. Once registered, you log in and select "Declaration" to begin your return for the relevant tax year.

The system pre-fills a lot of information based on your withholding tax records, but always double-check the numbers against your own documents. Errors in pre-filled data are common, and you're responsible for what you submit — not FBR.

Calculate before you file

Before you even open IRIS, it helps to know roughly what you owe. Run your salary or business income through our income tax calculator to see your exact slab, effective rate, and expected tax liability — it takes the guesswork out of reviewing what FBR's system calculates for you.

Deadlines and penalties

For tax year 2025-26, the standard filing deadline for individuals is September 30, 2026, though FBR frequently extends this by a few weeks. Missing the deadline doesn't just risk a penalty — it also drops you into the "late filer" category, which under the Finance Act 2025 now carries its own higher withholding tax rates, sitting between active filer and non-filer rates. File on time if you can; the compliance cost of being late has gone up.
