Every September across Pakistan, the same worry shows up in WhatsApp groups and family dinners. Did I file my tax return? Am I on the Active Taxpayer List? Will the bank now take more of my money?
Filing your income tax return in Pakistan is not a complicated thing once you see it in steps. You do it online on the FBR portal called IRIS. This guide walks you through who must file, what papers you need, and the exact steps. The law behind it is the Income Tax Ordinance 2001, and every figure below comes from the Federal Board of Revenue (FBR). You can read more of our tax guides for Pakistan and keep this article open alongside them.
Do you even need to file?
Not everyone has to. The law that decides this is Section 114 of the Income Tax Ordinance 2001. You must file a return for tax year 2026 if any of these is true for you:
- You are salaried and your taxable income goes above Rs 600,000 a year
- You run a business or freelancing with income above Rs 300,000 a year
- You hold a National Tax Number (NTN), no matter how low your income is
- You own a house plot of 250 square yards or more, or any flat, in a city area
- You own a car with an engine above 1000cc
- Your business uses a commercial electricity connection billed above Rs 500,000 a year
- You are registered with a professional body like the Pakistan Bar Council, PEC, PMDC or ICAP
The trap most people fall into: an NTN is for life. Once you get one, you are a filer for every year after, even if your income stops. A student who inherits a 1300cc car also must file, even with zero income of their own. The FBR filing page lists who is caught by this rule.
What tax year are you filing for?
Pakistan does not follow the January to December year. The tax year runs from 1 July to 30 June. Tax year 2026 covers the money you earned between 1 July 2025 and 30 June 2026, and the return goes in by 30 September 2026.
This confuses everyone the first time. The form you fill in September 2026 is for last year's income, not this year's. Filing for the wrong year is a common mistake.
Gather these before you log in
Have your papers together first. Chasing employers and banks at the last minute is how mistakes happen. You will want:
- Your salary slips and salary certificate from your employer, which show tax already taken under Section 149
- Bank account statements and profit on debt certificates for the full year
- Withholding tax certificates, from your mobile, electricity, token tax and car payments
- Property papers or sale deeds if you bought or sold any
- Your CNIC and your NTN login details
Getting these in one folder in August makes the whole thing take under an hour.
File your return on IRIS, step by step
All returns go through the FBR portal at iris.fbr.gov.pk. There is no paper form anymore. Here is the flow:
- Log in with your NTN or CNIC and password. If you have never filed, register on the portal first.
- Go to the Declaration menu and open Income Tax Return.
- Pick tax year 2026.
- Fill in your income. For salary, business, property, capital gains and other sources, each has its own box.
- Complete the wealth statement, which lists your assets and debts. FBR checks that it matches your income and your spending.
- Claim any credits you can, for donations or contributions that qualify.
- Review the tax it worked out. If you owe money, generate a PSID and pay it online.
- Submit and keep the acknowledgement.
Salaried employees usually only need to complete a short form called the Declaration 114(I), which the FBR makes available so salary earners do not have to fill the long return. The FBR step by step guide is on its video tutorials page.
The wealth statement trips most people up
People forget this part. The return is two forms, not one. You fill the income form and then the wealth statement, which lists what you own. Both must leave your draft folder and land in Completed Task, or nothing actually happened.
The wealth statement only goes through if it reconciles, meaning the change in what you own matches your income minus what you spent. If your assets grew by two carats while your declared income was tiny, the portal flags it and will not let you submit. This is the single biggest reason returns bounce back.
What happens if you miss the 30 September date
The deadline for individuals and small businesses is 30 September 2026. Companies get until 31 December. The FBR has extended this in some past years, always announced at the last moment, but do not plan around an extension that has not been announced yet.
If you miss it, three things happen. You face a penalty under Section 182, plus a default surcharge under Section 205 on any tax still owed. And FBR can take you off the Active Taxpayer List.
Leaving the list is the expensive part, and it goes on for years. A non-filer pays a far higher withholding rate on the same transactions a filer pays less for. Bank profit, property transfers and car registration all cost a non-filer more, often close to double. The FBR rate card shows the gap, and our guide to mobile and car withholding tax explains one everyday example.
Why filing early is worth it
The last week of September is chaos. Millions of people try to file at once and the portal slows down badly. Filing in August takes the same effort but the system is calm.
There is also a real money reason to file. Being on the list cuts your withholding rate on banking, property and vehicle transactions roughly in half. If your employer already takes tax from your salary, that does not make you a filer. Only a submitted return does. The same FBR system takes tax from your mobile top-up and token, something our guide to checking mobile and token tax shows in practice. The wider picture of how taxed income flows through withholding tax in Pakistan is worth a read before you start, and you can find every guide from the Lexiber home page.
The short of it
Check the Section 114 list. If you are caught by it, gather your papers, log into IRIS, and file for tax year 2026 before 30 September. It is the same every year after that. Doing it once removes the stress and the extra charges, and keeps the higher rates away from your bank account and your property paperwork.
