This guide covers getting your NTN from FBR — registering on the IRIS portal, confirming whether an NTN already exists for your CNIC, and what filing a return does for your ATL status.

Step 1

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.

Step 2

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.

Step 3

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.

Step 4

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 Outdated information causes delays in refund processing and may cause FBR correspondence to be sent to a wrong address.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

IRIS shows NTN linked to my CNIC but login password doesn't work

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.

My NTN was registered by my employer — how do I access my own account?

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.
