Filing an income tax return in Pakistan is now primarily an online process through the Federal Board of Revenue’s IRIS portal. Whether you are a salaried person, business owner or another taxpayer required to file a return, it is important to select the correct tax year, report your income accurately and review your tax information before submitting the return.
For Tax Year 2026, taxpayers should use the current electronic return available in IRIS. FBR notified the final electronic returns for Tax Year 2026 in September 2026, so taxpayers preparing or submitting a return should rely on the latest form and instructions available in IRIS.
This guide explains the general process of filing an income tax return online and the key information you should prepare before you begin.
What Is an Income Tax Return?
An income tax return is a declaration through which a taxpayer reports income and other required tax information to FBR for a particular tax year.
Pakistan’s normal tax year is a 12-month period ending on 30 June and is identified by the calendar year in which it ends. Therefore, Tax Year 2026 generally covers 1 July 2025 to 30 June 2026 for taxpayers following the normal tax year. Special tax years may apply in some cases.
Filing an income tax return should not be confused with simply obtaining an NTN.
| Process | What it means |
|---|---|
| FBR Registration / NTN | Registration of the taxpayer with FBR |
| Income Tax Return | Declaration of income and tax information for a tax year |
| Wealth Statement | Statement of assets, liabilities and related financial information where applicable |
| ATL Status | Whether the taxpayer is currently appearing on FBR’s Active Taxpayer List |
If you have not registered with FBR yet, read our guide on NTN registration online in Pakistan before starting your return.
What Do You Need Before Filing Your Tax Return?
The exact information required depends on your sources of income and financial circumstances. Before opening the return, it is useful to collect the records relevant to you.
These may include:
- CNIC and IRIS login credentials
- Salary certificate or annual salary information
- Business income and expense records
- Bank account information
- Property or rental income details
- Capital gains or investment information, where applicable
- Tax deducted by your employer, bank or other withholding agents
- Advance tax or other tax payments
- Details of assets and liabilities
- Previous year’s Wealth Statement
- Personal and household expenditure information needed for wealth reconciliation
- Supporting records for tax credits, deductions or exemptions being claimed
Do not enter an amount simply because it already appears in IRIS. Where information is pre-filled or available from FBR records, compare it with your own supporting documents before submission.
Step 1: Log In to FBR IRIS
Go to the official FBR IRIS portal and sign in using your registration number/NTN and password.
For an individual, the 13-digit CNIC is used as the NTN or Registration Number after registration with FBR. Companies and Associations of Persons (AOPs) receive a seven-digit NTN.
If you are filing for the first time and are not yet registered, registration must be completed before you can file an online income tax return. FBR identifies IRIS as its online system for filing income tax returns.
If you already have an NTN but do not have IRIS login credentials, FBR also provides an e-enrollment route for registered persons.
Step 2: Select the Correct Tax Year and Return
After logging in, open the relevant income tax return/declaration for the tax year you want to file.
For this guide, the relevant period is Tax Year 2026.
Be careful when selecting the tax year. A return filed for the wrong year does not satisfy the filing requirement for the year you actually intended to file.
Also use the return applicable to your taxpayer category and circumstances. The fields displayed in IRIS may vary according to the return and taxpayer profile.
Step 3: Review Your Personal and Registration Information
Before entering financial information, review your taxpayer profile and basic particulars.
Check details such as:
- Name
- CNIC/NTN
- Address
- Contact information
- Business information, where applicable
- Employer or other profile information where relevant
If important registration particulars are incorrect, they may need to be updated through the appropriate IRIS process rather than entering inconsistent information in the return.
Step 4: Enter Your Income
The next major part of the return is reporting income from the sources applicable to you.
Depending on your circumstances, this may include income from:
Salary
If you are employed, enter your salary information according to your employment and tax records.
FBR also provides a simplified declaration route, Form 114(I), for eligible salaried persons. FBR’s published guidance says this form is available to persons deriving income from salary and other sources where salary represents more than 50% of income.
Business
Business taxpayers may need to report business receipts, expenses and other relevant information according to the applicable return and their records.
Property
Rental or other taxable property income should be reported in the appropriate section where applicable.
Capital Gains
If you have taxable capital gains from shares, property, securities or another relevant asset, the applicable information should be declared under the appropriate section.
Other Sources
Income that does not fall into the main categories may need to be reported under income from other sources.
The correct tax treatment can vary considerably according to the nature of the income, so taxpayers with multiple or complex sources of income should consider obtaining professional advice before submission.
Step 5: Review Tax Deducted or Already Paid
A taxpayer may already have paid tax during the year through withholding or advance tax.
Examples can include tax deducted or collected through:
- Salary
- Banks
- Property transactions
- Vehicles
- Utilities
- Contracts or payments
- Other transactions subject to withholding
Review the information available in IRIS and compare it with your certificates, statements and other records.
A tax deduction appearing somewhere in your financial records should not automatically be claimed without checking whether it belongs to you, relates to the correct tax year and is legally adjustable against your tax liability.
Step 6: Review Your Tax Calculation
After entering the applicable income, deductions and tax information, review the resulting tax calculation carefully.
Depending on your circumstances, the return may result in:
- Tax payable
- No additional tax payable
- Tax already sufficiently paid through withholding/advance payments
- An amount potentially refundable, subject to applicable rules and FBR processing
Filing a tax return does not automatically mean that you have additional tax to pay.
The outcome depends on your taxable income, applicable rates, credits, tax already deducted or paid, and other relevant factors.
If an amount is payable, complete the required payment process before finalizing the return where required.
Step 7: Complete the Wealth Statement
For taxpayers required to complete it, the Wealth Statement is one of the most important parts of the filing process.
FBR’s general return-filing guidance states that online completion involves the Return of Income and Wealth Statement, and that successful submission is reflected when the relevant forms move from Draft to Completed Task in IRIS.
A Wealth Statement generally deals with your financial position, including relevant assets, liabilities and expenditures.
Depending on your circumstances, information may include items such as:
- Cash
- Bank balances
- Property
- Vehicles
- Investments
- Business capital
- Other assets
- Loans and liabilities
- Personal and household expenses
Accuracy is particularly important because the movement in your wealth needs to make sense in relation to your declared income, expenses and other explained inflows or outflows.
Step 8: Reconcile Your Wealth Statement
A common difficulty during return filing is wealth reconciliation.
FBR explains that the Wealth Statement must reconcile the movement between current-year and previous-year wealth with the difference between relevant income and expenditure. If the Wealth Statement does not reconcile, IRIS will not allow successful submission under the process described by FBR.
For example, if your net assets increased significantly during the year, there should normally be an explainable source for that increase, such as income, savings, a loan, gift, inheritance, asset disposal or another legitimate source, depending on the facts.
Do not insert artificial figures merely to force the reconciliation difference to zero. The figures should reflect your actual financial circumstances and supporting records.
We will cover this subject separately in our upcoming detailed Wealth Statement guide.
Step 9: Review the Entire Return Before Submission
Do not press Submit immediately after the figures appear to balance.
Review the complete return again.
Pay particular attention to:
- Correct tax year
- Income figures
- Tax deducted/collected
- Bank information
- Assets
- Liabilities
- Expenses
- Wealth reconciliation
- Tax payable
- Any exemptions, deductions or credits claimed
- Any information carried forward from previous records
This review is especially important for Tax Year 2026, because FBR has notified final electronic return forms for the year and taxpayers should work from the current IRIS return rather than relying solely on an older tutorial or previous-year return format.
Step 10: Submit the Income Tax Return
Once you are satisfied that the information is complete and accurate, use the submission option available in IRIS.
Do not assume that saving a return as a draft means it has been filed.
FBR’s guidance says successful submission can be confirmed when the relevant return and Wealth Statement have moved from the Draft folder to Completed Task.
After submission, retain a copy or acknowledgement of your filed return and relevant supporting records.
Income Tax Return Due Date in Pakistan
FBR’s general due-date guidance currently states:
| Taxpayer | General Due Date |
|---|---|
| Individual | On or before 30 September |
| Association of Persons (AOP) | On or before 30 September |
| Company | On or before 31 December |
| Company having a special tax year | On or before 30 September |
For Tax Year 2026, taxpayers should still check FBR’s latest notifications before relying on any extension or change in deadline. Never assume that a deadline will be extended merely because an extension occurred in a previous year.
Can You File an Income Tax Return After the Deadline?
Yes, filing after the due date may still be possible, but late filing can have consequences under tax law.
These may affect matters such as penalties and taxpayer status depending on the circumstances.
If your objective is to become an active filer after submitting your return, read our detailed guide on how to become a filer in Pakistan.
After filing, you can also use our guide to check your FBR ATL status by CNIC.
Can an Income Tax Return Be Revised?
A return is not necessarily impossible to correct after submission.
FBR’s published guidance states that an Income Tax Return may be revised within five years of originally filing it to correct an omission or wrong statement. FBR’s stated IRIS procedure requires an application for revision and, after approval, filing of the revised return.
FBR separately states that a Wealth Statement may be revised in IRIS before receipt of a notice under section 122(9), without an application seeking approval for revision.
Because revision can have legal and tax implications, it is better to review the original return carefully rather than treating revision as a substitute for accurate filing.
Common Mistakes to Avoid
Some common filing problems can be avoided by checking the return carefully before submission:
- Selecting the wrong tax year
- Treating NTN registration as equivalent to filing a return
- Leaving income sources undeclared
- Claiming tax deductions without checking supporting records
- Entering incorrect asset values or liabilities
- Forgetting relevant bank accounts or financial information
- Copying previous-year figures without reviewing changes
- Using artificial figures merely to reconcile the Wealth Statement
- Saving the return but failing to submit it
- Assuming that filing automatically guarantees immediate ATL status
If you are new to the FBR system, understanding the difference between registration, return filing and ATL status can prevent many of these mistakes.
Frequently Asked Questions
Where do I file my income tax return online in Pakistan?
Income tax returns are filed online through FBR’s IRIS portal. FBR describes IRIS as the online portal used for filing income tax returns.
Do I need an NTN before filing a tax return?
You must first be registered/e-enrolled with FBR to access the online filing system. For individuals, the 13-digit CNIC serves as the NTN or Registration Number after registration.
Does filing a return mean I have to pay income tax?
Not necessarily. Whether additional tax is payable depends on your income, applicable tax rules and tax already deducted or paid during the year.
Is a Wealth Statement required with the income tax return?
FBR’s general online filing guidance states that completing the online income tax return involves the Return of Income and Wealth Statement. The precise filing requirements can depend on the taxpayer and return being filed, so taxpayers should follow the current form presented in IRIS for their case.
How do I know whether my return has been successfully submitted?
According to FBR’s published guidance, successful submission is confirmed when the relevant Return of Income and Wealth Statement move from the Draft folder to Completed Task in IRIS.
What if I forgot my IRIS password?
Use the Forgot Password option on the IRIS login screen. FBR says verification codes are sent to the registered email address and mobile number, after which the password can be reset.

Registration, return filing and ATL status are related but distinct concepts. After filing, taxpayers should separately verify their status on FBR’s Active Taxpayer List.
Final Words
Filing an income tax return online becomes much easier when the required records are prepared before opening IRIS.
Start by confirming that you are registered with FBR, select the correct tax year, report each applicable source of income, review tax already deducted or paid, complete the required wealth information carefully and verify the entire return before submission.
For Tax Year 2026 in particular, use the current return available in IRIS and current FBR guidance rather than copying a previous year’s return or relying on an outdated tutorial.
Once your return has been submitted, keep your acknowledgement and supporting records and separately verify your ATL status where relevant.
