How to File Income Tax Return Online in Pakistan – Complete Guide 2026

Filing an income tax return is an important responsibility for taxpayers in Pakistan. The Federal Board of Revenue (FBR) provides an online system called IRIS that allows eligible taxpayers to register, prepare, submit, and manage their income tax returns without visiting an FBR office.

The online filing process may look complicated for first-time users, but it becomes much easier when the process is completed step by step. A taxpayer needs to provide information about income, expenses, tax deductions, assets, liabilities, and other financial details for the relevant tax year.

This guide explains how to file an income tax return online in Pakistan in 2026 through the FBR IRIS system. It covers registration, login, return forms, income details, Wealth Statement, tax calculation, submission, common mistakes, and confirmation of successful filing.

2. What Is an Income Tax Return?

An income tax return is a financial statement submitted to FBR by a taxpayer to declare income and other relevant financial information for a particular tax year.

The return normally contains information about different sources of income, taxes already deducted or paid, allowable adjustments, and the final tax position of the taxpayer.

For individuals, the information may include salary, business income, freelance income, property income, investment income, and other taxable receipts.

Filing a return does not always mean that additional tax has to be paid. Depending on the taxpayer's income and tax already deducted during the year, the taxpayer may have tax payable, no additional tax payable, or a refundable amount.

3. What Is FBR IRIS?

FBR IRIS is the Federal Board of Revenue's online platform for income tax-related services. Taxpayers can use IRIS to register with FBR, file income tax returns, submit Wealth Statements, make payments, revise certain submitted information, and perform other tax-related activities.

A taxpayer generally needs an IRIS account and valid login credentials to submit an income tax return online.

The IRIS system has made tax filing more convenient because taxpayers can complete many activities from home using a computer and internet connection.

4. Who Can File an Income Tax Return Online?

Individuals who are required to file an income tax return can generally use FBR's online IRIS system. Salaried employees, business owners, freelancers, professionals, landlords, investors, and other taxpayers may have filing obligations depending on their circumstances.

A person who is filing for the first time may need to complete registration before submitting a return.

Existing registered taxpayers who already have an NTN or registration number can log in to IRIS using their credentials and proceed with the relevant tax return.

Tax obligations depend on the taxpayer's income, status, activities, and applicable tax laws. Therefore, taxpayers should check their individual circumstances before deciding whether a return is required.

5. Things You Need Before Filing

Before starting the online filing process, prepare all relevant financial information. Having the information ready can save time and reduce mistakes.

Common information and documents may include:

• CNIC or NTN/Registration Number
• IRIS username and password
• Registered mobile number
• Registered email address
• Salary certificate, where applicable
• Bank statements or relevant banking information
• Details of tax deducted by employers or other withholding agents
• Business income and expense records
• Property or rental income information
• Details of investments
• Details of vehicles and other assets
• Bank balances
• Loans and liabilities
• Personal and household expenses
• Previous tax return information, where applicable

Not every taxpayer will need every document. The required information depends on the person's income sources and financial situation.

6. Register With FBR Before Filing

If you are a first-time taxpayer and do not already have an IRIS account, registration may be required before filing your return.

FBR provides online registration facilities for individuals through the IRIS system. During registration, the taxpayer provides personal, contact, residential, and other relevant information.

After successful registration, the taxpayer receives the required registration information and can use IRIS to access tax services.

Existing registered persons who have an NTN or registration number but do not have IRIS login credentials may also use the applicable e-enrollment facility.

7. Open the FBR IRIS Website

To begin filing, open the official FBR IRIS portal using a computer or another supported device with a reliable internet connection.

Enter your registration number or CNIC, password, and other required information to sign in.

Always make sure that you are using the official FBR website. Avoid entering your CNIC, password, OTP, or other confidential information on unknown websites.

If you forget your password, use the official password recovery option available on the IRIS login page.

8. Select the Relevant Tax Year

After logging into IRIS, select the relevant tax year for which you want to submit the return.

A tax year is a specific period used for reporting income and calculating tax. Selecting the wrong tax year can result in incorrect filing, so check the year carefully before entering financial information.

For example, Tax Year 2026 generally relates to the financial period ending June 30, 2026. Always check the applicable tax year and FBR instructions before submitting your return.

9. Choose the Appropriate Income Tax Return Form

The return form depends on the taxpayer's circumstances and sources of income.

A salaried individual may use the relevant salaried-person return where applicable. A person with business, professional, property, investment, or other income may need to provide additional information.

Do not select a form simply because it looks easier. The correct form should reflect your actual income and tax situation.

If you have multiple income sources, carefully review the applicable sections before entering information.

10. Enter Your Personal Information

The return may contain personal and registration information such as:

• Name
• CNIC or registration number
• Address
• Contact details
• Employer information, where applicable
• Business information, where applicable
• Other registration details

Review this information carefully. If your registration information has changed, you may need to update your registration details through the appropriate FBR process before or during filing.

Incorrect personal information can create problems later, particularly when FBR records are compared with other official information.

11. Enter Salary Income

If you are employed, enter your salary information according to your salary certificate and other relevant records.

Salary information may include annual salary, allowances, taxable benefits, and tax deducted by the employer.

Do not estimate figures if accurate information is available. Compare the information entered in IRIS with your employer's salary certificate or annual tax deduction statement.

If tax has already been deducted from your salary, enter the relevant withholding information correctly so that the system can calculate your final tax position.

12. Enter Business or Freelance Income

Business owners, freelancers, consultants, professionals, and self-employed persons should provide accurate information about their income.

Keep records of receipts, invoices, business expenses, bank transactions, and other supporting information.

Depending on the applicable tax rules, certain expenses may be relevant when calculating taxable income. However, taxpayers should only claim deductions or expenses that are legally allowable and properly supported.

Freelancers receiving payments through banks or online platforms should maintain proper records of their receipts and related expenses.

13. Enter Property and Rental Income

If you earn income from renting out a house, shop, office, agricultural property, or another relevant property, provide the required property and rental information.

Keep details of rental receipts, property ownership, and relevant expenses or deductions that may apply under the tax law.

If you have more than one property generating income, make sure each relevant source is properly reflected in the return.

14. Declare Other Sources of Income

Income may come from sources other than salary, business, or rent. Depending on the taxpayer's situation, this can include investment income, profit on debt, capital gains, dividends, or other taxable receipts.

Do not leave an income source undeclared simply because tax has already been deducted from it.

The purpose of filing a return is to provide a complete and accurate picture of your taxable income and relevant financial information.

15. Enter Tax Already Deducted or Collected

Many taxpayers have tax deducted at source during the year. For example, tax may be deducted from salary, bank profit, contracts, or certain transactions.

Enter the applicable withholding tax information carefully.

Where possible, compare the figures with available tax deduction certificates, employer records, bank information, or FBR tax records.

Incorrect withholding information can change the final tax calculation, so this section should be checked carefully before submission.

16. Review the Tax Calculation

After entering the required income and tax information, review the tax calculation generated by the system.

The final result may show tax payable, tax already paid or deducted, or a refundable amount depending on the taxpayer's circumstances.

Do not assume that the system's calculation should be accepted without checking the underlying information. If an income figure, deduction, withholding amount, or other entry is incorrect, correct it before submitting the return.

17. Complete the Wealth Statement

For many individual taxpayers, filing the income tax return also involves completing a Wealth Statement.

The Wealth Statement provides information about the taxpayer's assets, liabilities, personal expenses, and changes in wealth.

Depending on the taxpayer's circumstances, information may include:

• Cash
• Bank balances
• Vehicles
• Property
• Investments
• Loans
• Other assets
• Liabilities
• Personal expenses
• Wealth held inside or outside Pakistan where applicable

Enter figures carefully and keep supporting records.

18. Understand Wealth Reconciliation

Wealth reconciliation is one of the most important parts of the filing process.

The Wealth Statement should properly explain how the taxpayer's wealth changed during the relevant period. In simple terms, the increase or decrease in wealth should be consistent with the taxpayer's income, expenses, and other relevant financial movements.

If the Wealth Statement does not reconcile, IRIS may not allow successful submission.

Review your opening wealth, current assets, liabilities, income, expenses, and other relevant entries to identify the reason for any difference.

19. Review Bank Accounts and Assets

Before submitting the return, carefully review bank balances, property, vehicles, investments, cash, and other assets.

Do not intentionally hide an asset or provide inaccurate information.

Use reliable records such as bank statements, property documents, vehicle records, investment statements, and previous tax returns to prepare accurate figures.

Good record keeping also makes future tax filing easier.

20. Check Personal Expenses

Personal expenses are important when completing the Wealth Statement.

Depending on the form and taxpayer's circumstances, expenses may include household expenses, education, medical costs, utilities, travel, personal purchases, and other living expenses.

The figures should be realistic and supported by your financial circumstances.

A very low or unrealistic expense figure can create reconciliation problems or questions about how the taxpayer supported their household during the year.

21. Review the Complete Return

Before clicking the final submission option, review the entire return carefully.

Check:

• Tax year
• Personal information
• Salary income
• Business income
• Property income
• Other income
• Tax deductions
• Tax payments
• Assets
• Liabilities
• Expenses
• Wealth Statement
• Wealth reconciliation

A few minutes of review can prevent mistakes that may require correction later.

22. Submit the Income Tax Return

After completing all required sections, submit the return through IRIS.

Do not close the browser or leave the process incomplete while submission is being processed.

A return is not considered successfully filed merely because information has been entered or saved as a draft. The taxpayer should verify that the return has been successfully submitted.

FBR guidance indicates that successful submission is confirmed when the relevant return and Wealth Statement move from the Draft folder to Completed Tasks.

23. Confirm Successful Filing

After submission, check the IRIS dashboard and completed tasks.

Make sure that the return is no longer sitting only in the Draft section.

The taxpayer should retain a copy of the successfully submitted return and related documents for future reference.

It is also useful to keep copies of salary certificates, bank records, withholding certificates, expense records, and other supporting documents.

24. Download or Print Your Tax Return

After successfully filing the return, you can use the available print or download functions in IRIS to keep a copy.

Save the PDF file on your computer and, if needed, keep another copy in secure cloud storage or external storage.

A properly saved copy can be useful when applying for loans, visas, financial services, business requirements, or other situations where proof of tax filing may be requested.

25. What If You Have Tax to Pay?

If the return shows that additional tax is payable, the taxpayer should follow the applicable FBR payment process.

FBR provides electronic payment facilities through its tax payment system. Payment information should be generated and paid according to the applicable procedure.

After payment, keep the payment receipt or confirmation as part of your tax records.

Do not ignore a tax payable amount simply because the return itself has already been submitted.

26. What If You Are Entitled to a Tax Refund?

In some situations, the taxpayer may have paid or suffered more tax than the final tax liability.

The return may therefore show a refundable amount.

A refund claim is subject to the applicable FBR rules and procedures. Taxpayers should ensure that the information supporting the refund is accurate and properly documented.

Do not create an artificial refund by entering incorrect income, expenses, or withholding information.

27. How to Correct a Mistake After Filing

Mistakes can happen during online filing. If you discover an omission or incorrect statement after submission, check whether the return can be revised under the applicable tax rules.

FBR provides a procedure for revising an income tax return in appropriate circumstances.

Before revising a submitted return, carefully identify the original mistake and make sure the corrected information is accurate.

If the matter is complicated or involves a significant amount of tax, professional tax advice may be useful.
