Filing your income tax return is how you become - and stay - a filer on the FBR's Active Taxpayers List (ATL), which cuts the withholding tax you pay on banking, property and vehicles. The whole process runs online through IRIS, the FBR's electronic portal. This guide takes you from registration to a submitted return for Tax Year 2026, covers both salaried and business filers, and flags the mistakes that most often get returns rejected. If you want the wider picture first, start with our complete guide to income tax in Pakistan 2026-27.
Who must file and by when
Under section 114 of the Income Tax Ordinance 2001, you are required to file a return if you have an NTN, earn taxable income, own certain assets (a vehicle above a set engine capacity, immovable property over a threshold), or hold a commercial or industrial electricity connection. Every salaried person earning above the exempt threshold, and every registered business, should file.
Tax Year 2026 covers income earned from 1 July 2025 to 30 June 2026. Filing opened on the IRIS portal on 1 July 2026. The statutory deadlines are:
| Taxpayer type | Return form | Deadline (Tax Year 2026) |
|---|---|---|
| Salaried individual | 114(1) with 114(I) declaration | 30 September 2026 |
| Sole trader / business individual | 114(1) | 30 September 2026 |
| Association of Persons (AOP) | 114(1) | 30 September 2026 |
| Company (June year-end) | 114(1) company return | 31 December 2026 |
The FBR has repeatedly stated it does not intend to extend the 30 September date. File early - the IRIS portal slows badly in the final week of September as millions of returns land at once.
Documents and information you need
Gather everything before you log in - IRIS times out and half-finished returns are easy to lose. For a salaried filer the two most important inputs are your employer's NTN and your salary tax certificate.
- CNIC and NTN - your CNIC is your NTN for individuals.
- Salary tax certificate from your employer showing gross pay and tax deducted under section 149.
- Bank statements for all accounts for the full tax year, plus withholding tax deducted on profit.
- Withholding tax certificates - on bank profit, mobile top-ups, vehicle token tax, property transactions and dividends.
- Asset and liability details - property, vehicles, bank balances, investments, cash, gold, and any loans - for the wealth statement.
- Business records (business filers) - turnover, purchases, expenses, and closing stock for the profit and loss.
Not registered yet? You must have an NTN before you can file. Read our online NTN registration guide, then come back to this walkthrough.
Step-by-step: filing on IRIS
The IRIS 2.0 interface is menu-driven. Here is the full sequence for a straightforward salaried return; business filers follow the same path with extra income sections.
| Step | What to do on IRIS |
|---|---|
| 1 | Go to iris.fbr.gov.pk and log in with your CNIC/NTN and password. Forgot it? Use "Forgot Password" - a code goes to your registered mobile and email. |
| 2 | From the left panel click Declaration, then select Income Tax Return. |
| 3 | Choose Tax Year 2026 and the correct return type (salaried, business individual, AOP or company). Picking the wrong type is the most common first error. |
| 4 | Under Employment / Salary, enter salary income and the tax already deducted from your salary certificate. |
| 5 | Add other income - bank profit, rent, dividends, capital gains, and any business income in the relevant tab. |
| 6 | Enter tax credits and deductions - approved pension/provident fund, life insurance, and donations under the relevant sections. |
| 7 | Fill the Adjustable Tax tab with all withholding tax already paid (mobile, vehicle, property, banking) so it offsets your liability. |
| 8 | Open the Wealth Statement (116), list all assets and liabilities, and complete the reconciliation so opening wealth plus income minus expenses equals closing wealth. |
| 9 | Check the Computations tab. If tax is payable, click Create Payment to generate a PSID, pay via bank/app, and the CPR auto-links to your return. |
| 10 | Click Submit (enter the PIN if prompted), then download the acknowledgement slip as proof of filing. |
Salaried persons complete the simplified 114(I) declaration inside the return, which pre-arranges the salary and wealth fields for a quicker filing. Prefer not to wrestle with IRIS at all? Our income tax return filing service handles salaried and business returns end to end.
Extra steps for business and AOP filers
Sole traders, freelancers and AOPs use the same 114(1) return but must also complete a profit and loss section - turnover, cost of sales, expenses and net profit - and reconcile any tax withheld by clients under section 153. If your receipts fall under the minimum tax or final tax regimes, the correct tab matters, because it changes how much of your withholding is treated as final. The rules differ by structure - see our breakdown of business tax for sole traders, AOPs and companies to make sure you file under the right regime.
Common errors that get returns rejected
Most rejected returns and follow-up notices trace back to a short list of avoidable mistakes:
- Incomplete wealth statement - leaving out a car, a savings account or gold. Even small omissions flag the section 116 reconciliation and can trigger a risk-based audit.
- Wealth reconciliation not balancing - an unexplained jump in assets that your declared income does not support is the number one audit trigger.
- Wrong return type - filing a salaried return when you also run a business, or vice versa.
- Withholding not claimed - forgetting to enter tax already deducted on bank profit, mobile or vehicle, so you overpay.
- Mismatch with third-party data - deductions or income that do not match what banks and employers reported to the FBR.
- Filing but forgetting the ATL surcharge - late filers who do not pay the section 182A surcharge never appear on the ATL.
A submitted return does not automatically make you an active filer if it is late. You must also pay the ATL surcharge under section 182A before your name is added to the Active Taxpayers List. Check your status any time on the ATL guide.
Deadline, penalties and ATL surcharge
Missing 30 September has two separate costs - a penalty for late filing and a surcharge to get back on the ATL:
| Charge | Governing section | Amount |
|---|---|---|
| Late filing penalty | Section 182 | Higher of 0.1% of tax payable per day or Rs 1,000/day; minimum Rs 10,000 for salaried individuals |
| ATL surcharge - individual | Section 182A | Rs 1,000 |
| ATL surcharge - AOP | Section 182A | Rs 10,000 |
| ATL surcharge - company | Section 182A | Rs 20,000 |
Beyond the cash penalty, a non-filer or late filer pays sharply higher withholding on almost every transaction - see exactly how much in our filer vs non-filer guide. Late filing is still far better than not filing at all, which can escalate to a section 114 notice and a best-judgement assessment.
