TL;DR — Key Takeaways
  • IRIS (iris.fbr.gov.pk) is FBR's official online portal for income tax return filing filing, NTN registration, and payment
  • IRIS username is your CNIC number or NTN — password is set during first-time registration
  • The return filing section in IRIS is under "Income Tax → Returns → Filing"
  • Most WHT credits auto-populate from CPR data — verify them against your WHT certificates
  • Always download and save the "Acknowledgment Receipt" after submission as proof of filing

FBR IRIS (Integrated Revenue Management System) is Pakistan's official online tax portal for filing income tax returns, registering NTN, making tax payments, submitting wealth statements, and responding to FBR notices. IRIS was redesigned in recent years to improve usability, though first-time users often find the navigation confusing. This guide provides a section-by-section walkthrough of filing your TY2026 income tax return on IRIS.

Documents Checklist — Gather Before You Start

Filing goes much faster if every document is open in front of you before you log in to IRIS. Gathering these upfront also prevents session timeouts caused by hunting for paperwork mid-session:

  • CNIC and NTN — for yourself and, if applicable, your business
  • Salary certificate or Form-J from your employer showing gross salary and WHT deducted under Section 149
  • Bank statements for all accounts covering the full tax year, plus any profit/WHT certificates from banks
  • Property documents — ownership papers and FBR/DC valuation for any property bought, sold, or held during the year
  • Vehicle registration book for any vehicle owned
  • Business records — sales/purchase summary, expense receipts, and stock value if you run a business
  • Investment and savings certificates — prize bonds, mutual funds, National Savings Certificates
  • Prior year's wealth statement — needed to carry forward your opening wealth figures accurately

IRIS Login and Account Setup

To access IRIS for return filing:

  1. Go to iris.fbr.gov.pk in your browser (Chrome or Firefox recommended — avoid Internet Explorer)
  2. If you are a new user, click "Registration for Unregistered Person" and complete NTN registration first
  3. Existing users: enter your CNIC number (without dashes) as the username and your IRIS password
  4. If you have forgotten your password, click "Forgot Password" — a reset link is sent to the mobile number registered with FBR (the number you provided during NTN registration)
  5. After login, the IRIS dashboard shows your taxpayer name, NTN, tax circle, and registration status
Mobile number mismatch issue: The most common IRIS password reset failure is a mobile number that has changed since NTN registration. If the OTP does not arrive, visit your local FBR RTO with your CNIC to update the registered mobile number before the password can be reset online.

How to Enter Income on IRIS

Salary Income (Section 12): In the Income tab, select "Income from Salary." Enter employer name, NTN, and annual salary amount. Include bonus, allowances, and any perquisites received. If you had multiple employers during the year, add each separately. IRIS computes the tax on total salary using the applicable slab rates.

Business Income (Section 18): Enter gross revenue, cost of sales, and operating expenses to arrive at net profit. Ensure turnover is correctly entered — FBR crosschecks declared turnover against Section 113 minimum tax (1% of turnover). If you have books of accounts, prepare a simple profit and loss statement before starting the return.

Property Income (Section 15): Declare annual rental income received. Allowable deduction is 20% flat for repairs and maintenance. Enter tenant name and address if the rent is from commercial property. WHT certificates from tenants who are WHT agents should be entered in the WHT Credits tab.

Foreign Income: Foreign income earned by Pakistan residents must be declared under the relevant income head (salary, business, or other income). Enter in Pakistani rupees using the State Bank of Pakistan exchange rate on the date of receipt or the annual average rate.

IRIS 2.0 New Features for 2026 Filing

FBR upgraded IRIS to version 2.0 ahead of the Tax Year 2026 filing season, and several changes directly affect how you should approach the return this year. The redesign focuses on reducing manual data entry and catching wealth-statement mismatches before submission rather than after — both of which were the two biggest sources of errors and FBR notices in previous years' filings:

FeatureWhat Changed
Auto-populated WHTEmployer and bank WHT data now pre-fills automatically — always verify against your own certificates before submitting
Quick Mode for salaried filersA shorter single-page flow for taxpayers with salary-only income and no property/business/capital gains
Wealth reconciliation wizardOpening/closing wealth gap is now calculated automatically instead of manually
Auto-saveProgress now saves every few minutes on its own, in addition to the manual "Save as Draft" button

For a full breakdown of the IRIS 2.0 changes and a step-by-step walkthrough of the new Quick Mode, see our dedicated FBR New Tax Return Form 2026 guide.

Common IRIS Errors and How to Fix Them

  • "NTN/CNIC mismatch": Occurs when the NTN in your IRIS profile does not match your CNIC. Contact FBR helpline (051-111-772-772) or your RTO to align the records
  • "WHT credit not appearing": Some WHT credits take 7–14 days after bank payment to appear in CPR. If your employer's WHT deduction is not showing, enter it manually in the WHT Credits tab using the CPR number on your tax deduction certificate
  • "Wealth statement reconciliation error": IRIS flags when closing wealth does not reconcile with opening wealth + income − expenditure. Review each entry — most reconciliation errors are caused by forgotten prior-year assets or improperly entered bank balances
  • "Return already submitted": You can only submit once — to make corrections, use the "Revised Return" option under Income Tax → Returns. Revised returns can be filed within 5 years
  • Session timeout: IRIS sessions expire after 30 minutes of inactivity. Save your draft frequently using the "Save as Draft" button to avoid losing entered data
  • "Minimum tax applicable" warning: Appears when your declared business profit is below 1.25% of turnover — Section 113 requires you to pay minimum tax on turnover in such cases regardless of actual profit. This is not an error; it is the correct legal outcome for a low-margin or loss-making year
  • Portal extremely slow or unresponsive: Common in the final week of August and all of September as millions of taxpayers file simultaneously. File early — the same return that takes 20 minutes in July can take hours to submit in the last week of September due to server load

After Submission — What to Do

  1. Download the Acknowledgment Receipt: Immediately after submission, IRIS shows a confirmation page. Download and save the acknowledgment receipt (PDF) — this is proof of filing
  2. Verify on IRIS Filed Returns: Check Income Tax → Filed Returns to confirm your TY2026 return appears with status "Submitted"
  3. Check ATL status: Visit atl.fbr.gov.pk within 48 hours to verify you now appear as an active filer
  4. Inform your bank: If switching from non-filer to filer, inform your bank branch so they apply the reduced WHT rate (15% instead of 30%) on bank profit going forward
  5. File advance tax if required: If your annual tax exceeds Rs. 1 million and you are a business owner or professional, set up a quarterly advance tax payment schedule for TY2026–27

IRIS Pro Tips for Faster Filing:
  • Use Chrome or Firefox in incognito/private mode to avoid cached session conflicts with IRIS
  • Fill in income entries first, then deductions, then WHT credits — this order reduces reconciliation errors
  • If IRIS is slow during peak season (August-September), try filing during off-peak hours: early morning (5am-8am) or late night (11pm-1am)
  • Keep a PDF copy of each section as you complete it — if IRIS crashes, you have your entries documented
  • The wealth statement "Reconciliation" button at the bottom checks if your closing wealth is consistent with your declared income — use it before submitting

Filing Deadlines and Late Penalties 2026

Taxpayer TypeDue DateLate Penalty
Individual / Salaried30 September 2026Rs. 1,000/month or 0.1% of tax, whichever is higher
AOP / Partnership30 September 2026Rs. 5,000/month minimum
Company31 December 2026Rs. 10,000/month or 0.1% of tax/day

Beyond the direct penalty, missing the deadline drops you off the Active Taxpayer List until you file — meaning every withholding tax transaction (property, banking, vehicles) reverts to the higher non-filer rate until your name reappears on ATL, which is usually a far larger cost than the penalty itself.

Frequently Asked Questions

What is my IRIS username?

Your IRIS username is your 13-digit CNIC number without dashes (e.g., 3520212345678). If you registered with an NTN before CNIC-based login was introduced, your username may be your 7-digit NTN. Try both if unsure. The password is what you set during initial IRIS registration — if forgotten, use the "Forgot Password" option to reset via registered mobile OTP.

My employer already deducted WHT — do I still need to file a return?

Yes. Employer WHT deduction under Section 149 satisfies the tax payment obligation but does not replace the return filing obligation under Section 114. You must still file your own annual return on IRIS declaring your income, wealth statement, and WHT credits. The filed return is what places you on the ATL as an Active Taxpayer List (ATL).

How do I save progress on IRIS without submitting?

Use the "Save as Draft" button in the IRIS return interface. IRIS sessions expire after 30 minutes of inactivity and unsaved data is lost. Save as draft frequently — drafts are accessible in Income Tax → Returns → In Progress. You can work on a draft over multiple sessions before final submission.

I made an error in my submitted return — can I correct it?

Yes. File a revised return under Section 114(6) of the Income Tax Ordinance 2001. In IRIS, go to Income Tax → Returns → Revised Return and select the tax year. You can revise within 5 years of the original filing due date. FBR accepts revised returns without penalty for genuine corrections — however, if the revision significantly increases income, FBR may review the reasons.

Why does IRIS show a different tax amount than I calculated?

IRIS applies automatic calculations based on your income entries and the latest tax slabs programmed into the system. Discrepancies usually arise from: (1) income entries being categorized under the wrong head, (2) deductions entered incorrectly, (3) WHT credits not matching CPR data, or (4) minimum tax under Section 113 being applied when declared profit is below the minimum threshold. Review each tab carefully before submission.

Can I file IRIS from outside Pakistan?

Yes. IRIS is accessible from any country with internet access. Overseas Pakistanis commonly file their Pakistan income tax returns directly on IRIS from abroad. If IRIS is inaccessible due to geo-blocking in some countries, use a VPN with a Pakistan server. Alternatively, authorize a tax consultant in Pakistan to file on your behalf via the IRIS agent access feature.

Am I eligible for the new IRIS 2.0 Quick Mode?

Quick Mode is available only if your entire income for the year is salary-only, with no rental property, business income, or capital gains to declare. If any of those apply, you must use the standard detailed return, since Quick Mode does not have the fields to capture non-salary income sources correctly.
