An NTN (National Tax Number) is the unique FBR identifier assigned to every registered Pakistani taxpayer — it is obtained free of charge through the IRIS portal at iris.fbr.gov.pk using the CNIC as the primary identifier.
What an NTN Is and Why You Need It
The National Tax Number (NTN) is FBR's unique identifier for every taxpayer in Pakistan — individual, business, or company. It's required to file income tax returns, register for sales tax, open business bank accounts, and appear on the Active Taxpayer List (ATL). For most individual taxpayers, the CNIC now functions directly as the NTN in FBR's IRIS system.
Register on FBR IRIS
Go to iris.fbr.gov.pk and click Registration for Unregistered Person. Enter your CNIC — IRIS checks whether an NTN is already linked to your CNIC in its database. If an NTN exists, log in and update your password. If no NTN exists, fill in the registration form with personal details, address, employment or business information, and bank account details. Submit — IRIS generates your NTN instantly.
Verify NTN and Active Taxpayer Status
After registration, check whether you appear on the Active Taxpayer List (ATL) at atl.fbr.gov.pk by entering your CNIC. A newly registered NTN without a filed return shows as registered but not Active. To become Active and gain lower withholding tax rates across banking, property, and vehicle transactions, you must file at least one income tax return through IRIS.
Keep NTN Information Updated
Log into IRIS annually to update your contact information, home address, bank account details, and employment or business status. Outdated information causes delays in refund processing and may cause FBR correspondence to be sent to a wrong address. Your NTN is permanent and never changes, even if your address, employer, or personal circumstances change.
FBR and Filing Problems
Use the Forgot Password function on the IRIS login page — a reset link goes to the email registered in the account. If you no longer have access to that email, call FBR helpline 051-111-772-772 to update the registered email and then reset the password.
Use the Registration for Existing Taxpayer option on the IRIS homepage. Enter your CNIC and NTN to claim the account and set your own password for future access.
Frequently Asked Questions
FBR registration is legally required for all individuals with taxable income. Practically, FBR enforces registration more actively for those above the exemption threshold and those appearing in high-value transactions.
For individual taxpayers, FBR uses the CNIC as the primary identifier. Your CNIC effectively functions as your NTN, and the IRIS system links all tax records directly to your CNIC number.
Registration gives you an NTN. ATL Active status means you've also filed a return. Both are needed for the lower withholding rates — registration alone doesn't get you on the ATL. The ATL updates weekly (every Sunday night), so file your return, wait until the following Monday, then check atl.fbr.gov.pk to confirm Active status.
FBR has the legal authority to take action against high-value transaction earners who aren't registered. In practice, FBR targets non-filers based on visible markers — property purchases, vehicle registrations, foreign travel — rather than bank accounts directly. The practical risk for most people isn't account freezing; it's simply paying 2× the withholding tax rate on every financial transaction indefinitely.
Yes, if you hold assets that generate any income (rental property, bank savings over a threshold) or if you make significant purchases (property, vehicles above 1000cc). Filing a nil return keeps you on the ATL and reduces withholding rates on all future transactions. It costs nothing and takes 30 minutes once per year.
