How to File Income Tax Return in Pakistan for Tax Year 2026: Step-by-Step Guide

Published: June 17, 2026 · 9 min read

If you are a salaried individual, business owner, freelancer, or anyone with a taxable income source in Pakistan, the annual income tax return is not optional. The Federal Board of Revenue (FBR) requires every individual with income above the basic exemption threshold of Rs 600,000 to file a return for each tax year, and the deadline for Tax Year 2026 falls on September 30, 2026. The return you file in 2026 covers the income you earned between July 1, 2025 and June 30, 2026. The process is entirely online through the IRIS portal, but the steps matter — filing the wrong form, declaring income in the wrong column, or missing required attachments can trigger a defective return notice, late-filing penalties, or both.

Who must file an income tax return for Tax Year 2026

Under the Income Tax Ordinance, 2001, the following individuals are required to file an income tax return for Tax Year 2026 (income year ending June 30, 2026):

• Salaried individuals with annual taxable income above Rs 600,000
• Business owners and self-employed individuals regardless of income level (registration requirement)
• Freelancers and remote workers earning from foreign clients (Fiverr, Upwork, direct contracts)
• Property owners receiving rental income
• Capital gains earners from sale of securities, property, or other assets
• Non-residents with Pakistan-source income
• Any individual who owns a vehicle above 1000cc, a property, or a business — even with no taxable income — to maintain active filer status

The deadline for filing the TY2026 return is September 30, 2026. Extensions have been granted in some years, but the FBR has signalled for TY2026 that no further extension beyond September 30 is expected. After that date, late-filing penalties of Rs 40,000 or 0.1% of the gross turnover (whichever is higher) apply for non-compliance, and the taxpayer falls off the Active Taxpayer List (ATL) for the relevant year. Our guide to the disadvantages of late filers walks through the full penalty schedule.

The forms you need to know

FBR has three main return forms for individuals. Choosing the wrong one is a common error that leads to a defective return notice. Here is the breakdown:

For a typical salaried employee whose only income source is salary, ITR-1 is the right form. For a freelancer or someone who also has business income, ITR-3 is required, even if the salary component is larger. Our income tax return calculator is updated for TY2026 and produces a complete tax computation that you can directly enter into the IRIS form.

Pre-filing checklist

Before you log in to IRIS, gather the following. Most are required for the return fields, and missing items slow down the process.

• CNIC number and the CNIC of any dependants you are claiming credit for
• Salary income details: annual gross salary, tax deducted by employer, provident fund contributions, gratuity
• Bank account statements for the income year (July 2025 to June 2026) showing interest earned on savings, term deposits, and prize bonds
• Property documents for any rental income or capital gains
• Business income records: revenue, expenses, and net profit
• Freelance income records: gross receipts from Fiverr, Upwork, direct clients, and any FBR-issued WHT statements
• Investment records: capital gains from sale of shares, mutual funds, or property
• Foreign assets declaration if applicable (now encouraged by the abolition of CVT on foreign assets)
• Previous year’s return as a reference (not required, but useful)

Step-by-step: How to file on the IRIS portal

1. Register on IRIS if you haven’t already. Go to iris.fbr.gov.pk and click “Registration for Unregistered Person.” Enter your CNIC, name, mobile number, and email. You will receive a one-time password (OTP) to verify the mobile, and the system will issue a login ID and password via SMS. The full process is covered in our IRIS portal registration guide.
2. Log in to IRIS with your login ID and password. From the dashboard, navigate to “Declaration” → “Income Tax Returns” → “File Income Tax Return.”
3. Select the tax year as 2026 and the relevant form (ITR-1 for salary, ITR-3 for business/freelance). The system will pre-populate the taxpayer’s CNIC, name, address, and previous-year data.
4. Complete the “Salary” section with your annual gross salary, tax deducted by the employer, and any allowances. Cross-check with your June 2026 salary slip and the FBR’s withholding statement (available on IRIS under “Withholding Tax Statements”).
5. Complete the “Other Sources” section with bank interest, rental income, dividends, and prize bond winnings. Each item needs a separate line and the corresponding tax deducted at source.
6. Complete the “Capital Gains” section if you sold shares, mutual funds, property, or other capital assets during the year. The holding period and gain calculation follow the rules in the capital gains tax framework.
7. For business / freelance income, complete the “Business Income” section with revenue, cost of sales, and allowable expenses. For freelancers, the gross receipts from Fiverr and Upwork go into revenue, and the FBR’s freelance tax calculator produces the net computation.
8. Enter tax credits and deductions in the “Rebate / Credits” section. Common items include donations to approved charities, investments in specified savings schemes, and tuition fee credits for children’s education.
9. Enter assets and liabilities in the “Wealth Statement” section. This is required for anyone with total assets above Rs 10 million, and the values are matched against the FBR’s digital integration framework for cross-verification.
10. Review the auto-computed tax at the bottom of the form. The system calculates tax based on the new income tax slabs that took effect from July 1, 2026, applies the WHT already deducted by the employer or banks, and produces either a refund (if WHT exceeds final liability) or a balance payable (if the taxpayer owes more).
11. Upload required attachments — typically the wealth statement, depreciation schedule (for business), and any supporting documents for non-standard deductions.
12. Sign and submit the return using the OTP sent to your registered mobile. The system will generate an acknowledgement receipt with a tracking ID. Save this receipt — it is your proof of filing and is required for any follow-up with FBR.
13. Pay any balance due through the IRIS payment gateway, or via 1Link, JazzCash, Easypaisa, or a bank challan, before the September 30 deadline. The acknowledgement alone is not enough — the payment must be made to complete the return.

The new income tax slabs for Tax Year 2026 (effective July 1, 2026)

The Finance Act that took effect on July 1, 2026 introduced revised income tax slabs for the new tax year. The first two brackets are unchanged, but the brackets above Rs 2.2 million have been cut, and the 9% surcharge on incomes above Rs 10 million has been abolished. The full breakdown is in our salary tax slabs guide and our complete income tax slabs guide for TY2026.

For the return you file in 2026 (TY2026, income year ending June 30, 2026), the old slabs apply. For the return you file in 2027 (TY2027, income year ending June 30, 2027), the new slabs apply. The IRIS portal automatically applies the correct slab to whichever tax year you select.

Common mistakes to avoid

What happens after you file

Once the return is submitted and payment (if any) is confirmed, the FBR processes the return and updates your record on the Active Taxpayer List. The ATL is updated daily, and your name appears on the public list the next day. Active filer status gives you access to lower withholding tax rates on banking transactions, vehicle purchases, and property dealings, and is required for many other regulatory processes. Our FBR filer status check guide walks through the verification process.

For refunds — which arise when the WHT deducted at source exceeds the final tax liability — the FBR typically issues refunds within 60-90 days of the return being processed, although the actual timeline varies. The refund is credited to the bank account registered in the IRIS profile.

Need help?

For salaried individuals with a single employer, no rental income, and no foreign income, the return can be self-filed in 30-45 minutes. For business owners, freelancers, and anyone with multiple income sources, professional advice is recommended. Our complete tax filing guide for 2025 covers the same process in more detail, and our wider guide to government schemes includes the tax-related programmes that small businesses should be aware of.
