How to File Your Income Tax Return on FBR IRIS – Complete Step-by-Step Guide for Pakistan 2026

Every year, around August and September, millions of Pakistanis start asking the same question: "How exactly do I file my income tax return?" The FBR IRIS portal can feel intimidating the first time you open it — too many menus, unfamiliar terms like wealth statement and PSID, and the constant worry that you might make a mistake and get a notice.

This guide is written to take that anxiety away. If you are a salaried employee filing for the first time, or someone who has been meaning to file for years but kept putting it off, by the end of this guide you will know exactly what to do, step by step. We have also included the Budget 2026-27 tax slabs so your return reflects the correct rates. Before you begin, use our Income Tax Calculator to estimate what you owe — it takes 30 seconds and gives you a target number before you open IRIS.

📋 Who is Legally Required to File a Tax Return in Pakistan?

Many salaried Pakistanis believe their employer's monthly tax deduction satisfies all their obligations. It does not. Under the Income Tax Ordinance 2001, you are legally required to file an annual return if any of the following apply:

• Your annual income from any source exceeds PKR 600,000
• You own immovable property with land area of 500 sq yards or more, or a flat larger than 2,000 sq ft
• You own a motor vehicle of 1,000cc or above
• Your electricity or gas bills exceed PKR 500,000 in a year
• You are a member of a club with monthly fee exceeding PKR 2,000
• You hold a foreign passport or have travelled abroad on a visit visa
• You have any foreign income or foreign assets
• You are a director of any company in Pakistan
• Your bank account balance exceeds PKR 500,000 at any point during the year

Even if none of the above applies and you owe zero tax, voluntarily filing a nil return is strongly recommended — it puts you on the FBR Active Taxpayer List (ATL), reduces your withholding tax on dozens of transactions, and builds a clean tax history. A nil return takes under 20 minutes.

📅 Pakistan's Tax Year — July to June, Not January to December

Pakistan's tax year runs from July 1 to June 30 — not the calendar year. So "Tax Year 2026" covers income earned from July 1, 2025 to June 30, 2026, and the return is due by September 30, 2026. This is also called "Financial Year 2025-26" or "FY 2025-26." When you open IRIS and select a tax year, always make sure you select the correct one matching the period your income was earned.

⚠️ Penalties for Not Filing — What FBR Can Do

Failure to file a return is a separate legal offence from non-payment of tax. Even if your employer deducted the full correct amount of tax, not filing the return exposes you to:

• PKR 40,000 minimum penalty for non-filers whose income exceeds the taxable threshold (Section 182)
• Removal from ATL — immediately triggers higher withholding tax on all banking, property, and vehicle transactions
• 0.6% WHT on cash withdrawals above PKR 50,000/day — filers pay 0%
• Double WHT on property — non-filers pay 2.5% on purchase and 5.5% on sale; filers pay 1.25% and 2.75% respectively
• Best judgment assessment — FBR can estimate your income and raise a tax demand with penalties if you remain a non-filer for years

Filing a nil or low-income return is always better than not filing at all. The cost of non-filer status in WHT alone far exceeds any inconvenience of filing. Read our FBR ATL complete guide for the full financial impact breakdown.

Step 1 — Register on FBR IRIS (First-Time Filers Only)

If you have never filed before, you need to register on IRIS first. This takes about 10 minutes and only needs to be done once.

1. Go to iris.fbr.gov.pk on any browser
2. Click the "Registration" button on the homepage
3. Enter your CNIC number (13 digits without dashes) and click Verify
4. If you already have an NTN linked to your CNIC, it will show automatically. If not, you will be given a new one.
5. Enter your name, address, mobile number, and email
6. Click Submit — you will receive your IRIS password via SMS within a few minutes
7. Log in with your CNIC as username and the SMS password. Change the password immediately after first login.

Step 2 — Open the Income Tax Return Form

1. Log into IRIS at iris.fbr.gov.pk
2. In the left menu or top navigation, click on "Returns"
3. Select "Income Tax Return"
4. Click "Create Return"
5. Select the Tax Year — for the year ending June 30, 2026, select Tax Year 2026
6. Select your Income Source Type — most salaried people select "Salary". If you have business income, select "Business." If both, select "Salary and Business."
7. Click Create — the return form opens

Step 3 — Fill the Income Section

The income section has separate rows for different types of income. Fill only the ones that apply to you:

Salary Income (Section 12)

This is the most important section for salaried employees. Your salary certificate from your employer will have all the numbers:

• Basic Salary: Annual basic pay (monthly × 12)
• House Rent Allowance (HRA): Annual HRA received
• Medical Allowance: Annual medical allowance
• Conveyance Allowance: Annual conveyance
• Other Allowances: Utility, special, performance bonuses — all taxable
• Tax Deducted at Source: Total income tax deducted by employer during the year

IRIS will automatically calculate your tax based on what you enter. Cross-check it with our Income Tax Calculator using Budget 2026-27 slabs to make sure it matches.

Other Income Sources

Declare all other income honestly — FBR's data matching system now cross-checks against bank records, property registries, and withholding tax returns filed by banks and employers:

• Profit on bank deposits: Shown on your bank statement or annual profit certificate. WHT already deducted at 15% (filer) is credited.
• Rental income: Annual rent received from property you own. Taxable under "Income from Property."
• Capital gains: If you sold property or shares during the year. Enter under respective CGT sections.
• Prize bonds: Any winnings from National Savings prize bonds.
• Foreign income: Remittances for services rendered abroad, salary from foreign employer.

Step 4 — Claim Your Deductions and Tax Credits

This is the step most first-time filers skip — and it costs them money. IRIS has a dedicated section for deductions and credits. Enter everything that applies:

Step 5 — Complete the Wealth Statement

The Wealth Statement is the part that most people dread — but it is simpler than it looks if you approach it systematically. It is a snapshot of everything you own and owe as of June 30, 2026.

Assets to Declare

• Immovable property: All plots, houses, flats, agricultural land — declared at cost of purchase (not market value). Include address, area, and year of purchase.
• Motor vehicles: All cars, motorcycles, commercial vehicles. Declared at cost of purchase.
• Cash in hand and at bank: Bank balances as of June 30. Cash above PKR 500,000 should be declared.
• Investments: Mutual funds (NAV as of June 30), shares (cost or market value), National Savings certificates (face value), prize bonds (face value).
• Gold and jewellery: Weight in grams and estimated value. Family jewellery is declared at market value.
• Business assets: If you run a business, declare fixed assets, stock in trade, and receivables.
• Foreign assets: Any assets held outside Pakistan must be declared.

Liabilities to Declare

• Bank loans (home, car, personal) — outstanding balance as of June 30
• Credit card outstanding balance
• Business borrowings
• Loans from family or friends (if formal)

Wealth Reconciliation — The Critical Part

IRIS will ask you to reconcile: your closing wealth (this year) minus opening wealth (last year) should equal your taxable income minus taxes paid minus personal expenses. If this does not balance, FBR may ask for an explanation.

For personal/household expenses (food, utilities, school fees, medical, clothing, travel), IRIS has a standard expense section. Enter a realistic annual household expense figure. For a family of 4 in a major city, PKR 40,000 to PKR 80,000 per month is a reasonable range.

Step 6 — Calculate Tax and Pay Any Balance

After you complete all sections, click "Calculate" in IRIS. The system will compute:

• Total taxable income
• Gross tax liability based on applicable slabs
• Less: Tax credits (donations, education, health, mortgage)
• Less: Tax already paid (withheld by employer, bank WHT, property WHT)
• Net tax payable — or refund due

If the result shows tax payable, you need to pay before submitting the return. Here is how:

1. In IRIS, click "Create PSID" (Payment Slip ID)
2. The system generates a 17-digit PSID number
3. Take this PSID to any bank branch — HBL, MCB, UBL, Meezan, Bank Alfalah, etc. — and pay the amount
4. Alternatively, pay online through your bank's internet banking or mobile app under "FBR Tax Payment"
5. After payment, the PSID status in IRIS changes to "Paid" — this may take a few hours to update

Step 7 — Submit the Return and Get Your Acknowledgment

1. Review all sections one final time — look for any fields showing errors or highlighted in red
2. Click "Verify" to check for any system errors
3. Click "Submit"
4. IRIS will show a confirmation screen with your Acknowledgment Number — save or print this
5. You will also receive an acknowledgment email at the address registered in IRIS

That is it. Your return is filed. Your ATL status will update to Active on the next Monday after FBR processes your return (usually within 2–3 working days).

Common Mistakes to Avoid

❌ Not Declaring All Bank Accounts

FBR receives WHT data from all banks. If you have a bank account but do not declare it in your wealth statement or income section, FBR's matching system will flag it. Declare every account you hold — savings, current, joint, foreign currency.

❌ Understating Property Values

Property must be declared at cost of purchase (what you actually paid, supported by the sale deed). Never understate. FBR cross-checks registered sale deeds from sub-registrar records.

❌ Forgetting Employer's Salary Certificate

Every employer who deducts WHT must issue a salary certificate (Form of Annual Statement under Section 165). Ask your HR or accounts department for this. The numbers on this certificate must match exactly what you enter in IRIS.

❌ Not Filing a Wealth Statement

The income return and wealth statement are two separate submissions in IRIS but both are mandatory. Many people complete the income return but forget to submit the wealth statement. Check that both show "Submitted" in your IRIS dashboard.

❌ Missing the September 30 Deadline Without a Plan

If you know you will miss the deadline, plan for the late filing surcharge (PKR 1,000 per month, max PKR 20,000). Do not simply skip the year — that removes you from the ATL and costs you far more in WHT than the surcharge. Read our FBR ATL guide to understand the full cost of non-filer status.
