How to File Income Tax Return in Pakistan 2026 (Complete IRIS Guide)
Filing an income tax return in Pakistan is an important tax-compliance requirement for persons who fall within the filing requirements under the Income Tax Ordinance, 2001. Returns are generally filed online through the FBR IRIS portal.
Tax Year 2026 relates to the income year ending on 30 June 2026. For individuals and Associations of Persons (AOPs), the ordinary filing due date is 30 September, while companies generally have a 31 December due date, subject to the applicable tax year and law.
This guide explains the basic IRIS filing process, required documents, income details, Wealth Statement, tax payment, common mistakes, and what to do after filing.
Who May Be Required to File an Income Tax Return?
The filing requirement depends on the taxpayer’s income, assets, registration status and other circumstances specified in the Income Tax Ordinance, 2001.
Depending on the applicable provisions, filing requirements can apply to persons who, for example:
- Have taxable income above the applicable threshold.
- Hold an NTN or are otherwise required to be registered with FBR.
- Own certain immovable property or a motor vehicle meeting the statutory criteria.
- Have a qualifying commercial or industrial electricity connection.
- Are members of specified professional bodies, chambers or trade associations.
- Were charged to tax in preceding tax years.
- Have other circumstances that trigger a return or statement requirement under the law.
Even where little or no tax is ultimately payable, a person may still have a filing obligation. Filing can also be relevant to maintaining or obtaining active taxpayer status and managing withholding-tax consequences.
Documents Required for Tax Year 2026
Before starting your return, keep the following information and documents available, where applicable:
- CNIC / NTN and IRIS login credentials.
- Salary certificate or annual salary/income details.
- Bank statements for the relevant tax year.
- Withholding-tax certificates or tax deduction details.
- Details of business, freelance or professional income.
- Rental or property-income details.
- Capital-gain information, where applicable.
- Details of foreign income and assets, where applicable.
- Details of assets and liabilities as at 30 June 2026.
- Previous year’s Wealth Statement and relevant opening balances.
Step-by-Step: How to File Your Return on FBR IRIS
Step 1: Log in to IRIS
Access the FBR IRIS portal and log in using your NTN/registration details and password.
First-time filers generally need to complete registration/e-enrolment before filing a return. FBR confirms that registered taxpayers can access IRIS using their NTN or registration number and password.
Step 2: Check and Update Your Profile
Review your profile information and update any required details, such as contact information, bank-account information or other taxpayer particulars, where applicable.
Step 3: Start the Income Tax Return
From the relevant IRIS menu, select the income tax return applicable to your circumstances and choose Tax Year 2026.
The exact form available to you can depend on your taxpayer category and income sources. Salaried individuals who meet the relevant conditions may have access to the simplified salaried-person return/wizard provided through IRIS.
Step 4: Enter Your Income
Declare all relevant sources of income for the tax year, such as:
- Salary
- Business or professional income
- Property or rental income
- Capital gains
- Profit on debt / bank profit
- Other taxable income
- Foreign income, where applicable
Use supporting documents and records to ensure that the figures entered into IRIS are accurate and consistent.
Step 5: Enter Tax Already Deducted or Paid
Enter applicable withholding tax, advance tax and other allowable tax adjustments or credits supported by your records.
Carefully compare the information with your bank statements, salary certificate, withholding certificates and other available records.
Step 6: Complete the Wealth Statement
Where required, complete the Wealth Statement showing your assets, liabilities, personal expenses and other relevant information.
FBR explains that successful filing requires completion of the relevant Income Tax Return and Wealth Statement, and that the Wealth Statement must reconcile with the change in wealth during the year.
How Does Wealth Reconciliation Work?
In simple terms, your closing wealth should reconcile with your opening wealth after taking into account your income and expenses for the year.
If the figures do not reconcile, IRIS may not allow successful submission of the Wealth Statement and return.
Step 7: Review Your Tax Calculation
Review the computation generated by IRIS. Check your income, deductions, tax credits, withholding tax and resulting tax payable or refundable amount.
Step 8: Pay Tax, If Payable
If additional tax is payable, follow the applicable FBR process for generating the payment slip and making payment through an available banking/payment channel.
Keep the payment evidence for your records.
Step 9: Submit the Return
After completing all required sections, submit the return and Wealth Statement through IRIS.
FBR states that successful submission is confirmed when the relevant forms move from the Draft folder to Completed Task.
Save the acknowledgement/confirmation and supporting records for future reference.
Important Tax Filing Deadlines for Tax Year 2026
| Taxpayer | General Due Date |
|---|---|
| Individuals & AOPs | 30 September |
| Companies | 31 December |
| Companies with a special tax year | 30 September |
These are the general due dates published by FBR; a taxpayer’s specific circumstances and any lawful extension should also be considered.
What Happens If You File Late?
A return can still be filed after the due date, but late filing may result in penalties or other consequences under the applicable law. Late filing can also affect active taxpayer status and related withholding-tax treatment.
FBR confirms that returns can be filed after the due date through the prescribed IRIS process.
Common Mistakes to Avoid
- Selecting the wrong tax year.
- Entering income figures that do not match supporting records.
- Forgetting applicable withholding-tax deductions.
- Failing to reconcile the Wealth Statement.
- Omitting assets, liabilities or major transactions.
- Entering incorrect bank-account or profile information.
- Failing to save the draft while completing a lengthy return.
- Assuming that saving a draft means the return has been submitted.
- Not keeping the final acknowledgement and supporting documents.
After Filing Your Tax Return
After submission:
- Confirm that the return and required Wealth Statement have been successfully completed in IRIS.
- Save your acknowledgement and payment records.
- Keep supporting documents and financial records safely.
- Check your taxpayer/ATL status where relevant.
- If you discover an error, consider the applicable procedure for revising the return or Wealth Statement.
FBR states that an income tax return may be revised under the applicable procedure to correct an omission or wrong statement, while Wealth Statement revision has its own applicable requirements.
Frequently Asked Questions
