How to File Income Tax Return in Pakistan (FBR IRIS Guide 2026)

Filing an income tax return in Pakistan is mandatory for millions of salaried employees, business owners, and freelancers — and staying on the Active Taxpayer List (ATL) saves you money on dozens of daily transactions, from bank withdrawals to property deals.

This guide walks you through who must file, what documents you need, and how to complete the process on the FBR IRIS portal.

Who Must File an Income Tax Return?

You are required to file an annual return if any of the following apply:

Your annual income exceeds Rs. 600,000
You hold an NTN (National Tax Number)
You own property, a vehicle, or foreign assets
Your employer deducts WHT from your salary (file to reconcile and claim refunds)
You have any business income
You are a company director
You received foreign remittances exceeding Rs. 1 million in the year

Even if your income is below Rs. 600,000, filing is worth it. ATL status means lower withholding tax rates on bank transactions, property purchases, and vehicle registration.

Documents Required

Before you start, gather:

NTN / CNIC — your tax registration and identity
Salary certificate / Form 16 — from your employer showing annual salary and WHT deducted
Bank statements — all accounts for the tax year
Property documents — if you own any property
Business records — profit/loss, invoices (for sole proprietors)
Zakat deduction certificate — if Zakat was deducted at source (reduces tax liability)

Step-by-Step: Filing on FBR IRIS

Step 1: Register / Log In Visit iris.fbr.gov.pk. New users must register using their CNIC and mobile number to get a password.

Step 2: Select the Return Type

Salaried employees: Income Tax Return (Salary)
Business owners / freelancers: Income Tax Return (Business)

Step 3: Fill In Income Details Enter your gross salary, allowances, and any other income. For freelancers under the Digital Nation Act, your foreign remittance income is taxed at 0.25% final tax — enter in the relevant section.

Step 4: Enter Deductions and Credits

WHT already deducted by employer (from Form 16)
Zakat deducted at source
Charitable donations (FBR-approved organisations)

Step 5: Calculate and Pay IRIS auto-calculates your tax. If WHT exceeds your liability, you will see a refund due. If additional tax is owed, pay via PSID (CPR system) at any bank branch or online.

Step 6: Submit Verify and submit. You will receive a filing acknowledgement. Your name will appear on the ATL within 24–72 hours.

Frequently Asked Questions

I am a salaried employee — my employer already deducts tax. Do I still need to file?

Yes. Filing reconciles your WHT against your actual liability. If your employer over-deducted, you receive a refund. It also keeps you on the ATL.

Can I file the return myself, or do I need a tax consultant?

Salaried employees can file independently via IRIS — it is designed for self-filing. Business returns with multiple income sources are more complex and may warrant professional assistance.

What happens if I miss the September 30 deadline?

You can still file a late return. FBR charges a penalty of Rs. 1,000/month for individuals with only salary income. However, your ATL status will lapse until you file.
