To register a business with FBR, visit iris.fbr.gov.pk, click "Registration for Unregistered Person," fill out Form 181 with your CNIC and business details, and submit. Your NTN is issued instantly for sole proprietors. The process is free, takes under 30 minutes, and is entirely online.
Why Register Your Business with FBR?
FBR registration is not just a legal obligation — it also enables return filing and ATL status. Persons not appearing on the Active Taxpayers List can face higher withholding on many specified transactions, but the uplift and conditions differ by section.
| Transaction | Filer Rate | Non-Filer Rate |
|---|---|---|
| Cash withdrawal from bank (above Rs 50,000/day) | 0% | 0.8% |
| Property purchase (up to Rs 50M) | 1.5% | 3% |
| Import of goods (Part II — commercial) | 3.5% | 7% |
| Ecommerce COD sales (Sec 153(2A)) | 2% | 4% |
| Prize bond winnings | 15% | 30% |
Who Must Register with FBR?
Under the Income Tax Ordinance 2001, the following are required to register and file annual returns:
- Any person with annual business income exceeding Rs 600,000
- Any person owning property worth Rs 500,000 or more
- All companies incorporated under the Companies Act
- Any Association of Persons (AOP/partnership)
- Anyone with a foreign income source or foreign asset
Voluntary registration is always recommended even if you fall below these thresholds. The filer benefits — lower WHT on every transaction — far outweigh the effort of filing a simple annual return.

Step-by-Step: How to Register on IRIS
Go to IRIS — FBR's Online Portal
Open iris.fbr.gov.pk and look for "Registration for Unregistered Person" on the login page. Do not use the regular login if you don't have an account yet.
Enter Your CNIC & Mobile Number
Enter your 13-digit CNIC and the mobile number registered to it. FBR sends a One-Time Password (OTP) to verify your identity.
Fill Out Form 181
Complete the registration form with your personal details, address, business type, business activity code, and bank account details.
- Select your Business Activity Code from the dropdown
- Add your Bank Account / IBAN
- Add Property Details if applicable
Submit and Receive Your NTN
After submitting Form 181, FBR processes your registration. For sole proprietors, the NTN is issued immediately and equals your CNIC. You'll receive IRIS credentials via SMS/email.
Log In to IRIS and Complete Your Profile
Review your taxpayer profile, update any missing information, and confirm your registration status is marked Active.
File Your First Tax Return
Registration alone does NOT make you an active filer. You must file at least one annual return by the applicable FBR deadline for the relevant tax year. Even a nil return counts. See: Small Business Tax Guide →
Registration by Business Type
Sole Proprietorship
The simplest registration. Your NTN = your CNIC. Register as an "Individual" in IRIS. No corporate documents needed.
Partnership / AOP
Partnerships register as an Association of Persons (AOP) with their own separate NTN. All partners should also have individual NTNs. You'll need the partnership deed.
Private Limited Company
Companies registered with SECP must separately register with FBR. Select "Company" in IRIS and upload the SECP incorporation certificate.
SECP ≠ FBR. SECP registration (forming a company) and FBR registration (getting an NTN) are two separate processes. You need both. SECP creates your company legally; FBR registers you for taxation.
What to Do After Getting Your NTN
- File your annual income tax return by the applicable FBR deadline for the relevant tax year. Verify the current deadline before submission because FBR may issue extensions or taxpayer-specific guidance.
- Check Sales Tax (STRN) registration separately. Liability depends on whether you are an importer, manufacturer, wholesaler, distributor, tier-1 retailer, or another prescribed person; services usually fall under provincial rules. See our Sales Tax Registration Guide →
- Open a separate business bank account and link it in IRIS
- Maintain business records — invoices, receipts, payroll — for at least 5 years
- Monitor your IRIS inbox — FBR sends all audit notices and demand letters through IRIS
When to Update Your IRIS Business Profile
Registration is not a one-time formality. Update your IRIS profile whenever your business address, mobile number, email, bank account, principal activity, branch location, or ownership structure changes. This matters because FBR notices, OTPs, verification messages, and registration records are linked to the information saved in your profile. If the profile is old, you may miss an important notice or face delays when a bank, marketplace, withholding agent, or client asks for tax verification.
Before the annual return season, compare your IRIS registration details with your CNIC, business bank account, invoices, lease agreement, and SECP records where applicable. For a sole proprietor, the most common issues are an old phone number, wrong business activity, or inactive email. For companies and AOPs, also check directors, partners, registered address, and contact person details. Clean profile data makes filing easier and reduces avoidable mismatch problems later.
Common Mistakes to Avoid
- Using a mobile number not registered against your CNIC — OTP won't be delivered
- Selecting the wrong business activity code
- Registering but never filing a return — registration alone does not make you an active filer
- Not updating IRIS when your address or bank account changes
- Ignoring IRIS notices — these can escalate to enforcement quickly

Final Compliance Checklist
Before relying on any tax estimate, match the rule with the actual document in your hand: bank certificate, IRIS registration, ATL record, payment receipt, challan, or official portal result. Tax disputes often happen because the rate was correct but the taxpayer could not prove the status, payment, or source document used for the calculation.
Keep screenshots, certificates, receipts, and notices by tax year. A clean folder makes it easier to file, revise, respond to a notice, or explain a deduction that appears later in IRIS.
