TL;DR: NTN (National Tax Number) is your income tax registration — everyone who earns above the taxable threshold needs one. STRN (Sales Tax Registration Number) is separate, required only for businesses that supply taxable goods or services above the registration threshold. Most individuals only ever need an NTN. WhatsApp 0324-0400564 to check which applies to you.
NTN and STRN get confused constantly because both are FBR registrations with similarly formatted numbers — but they cover completely different taxes, apply to different people, and have separate filing obligations.
NTN — National Tax Number
- Registers you for income tax — tax on what you earn, whether from salary, business profit, freelance income, or property
- For individuals, this is your CNIC itself once registered
- Required by anyone earning above the taxable income threshold, regardless of business type
- Leads to filing an annual income tax return
STRN — Sales Tax Registration Number
- Registers your business for sales tax — a tax on the sale of taxable goods or specified services, collected from customers and deposited with FBR (or PRA/SRB for services in Punjab/Sindh)
- Only required if your business supplies taxable goods/services above the applicable registration threshold, or operates in a category FBR mandates registration for (manufacturers, importers, wholesalers, large retailers, and certain service providers)
- Leads to filing a monthly sales tax return, separate from your annual income tax return
Who Needs Which
- Salaried individual: NTN only
- Freelancer/IT exporter: NTN only (export services are typically exempt from local sales tax registration)
- Retail shop selling taxable goods: both NTN and STRN
- Manufacturer or importer: both NTN and STRN, usually mandatory
- Service provider (consultancy, agency, etc.) above provincial threshold: NTN plus a provincial sales tax registration (PRA, SRB, KPRA, or BRA depending on province)
Do They Have to Match?
Your STRN registration is built on top of your existing NTN — you can't register for sales tax without an NTN already in place. So the sequence is always: get your NTN first, then add STRN if your business activity requires it.
Frequently Asked Questions
Can I have an NTN without an STRN?
Yes — this is the most common situation. Most individuals and many small businesses only need an NTN and never require sales tax registration.
Can I have an STRN without an NTN?
No — NTN registration is a prerequisite for STRN. You always need the NTN first.
How do I know if my business crosses the sales tax threshold?
Thresholds and category rules vary by business type and province — WhatsApp your business details and NTNWaale will confirm whether STRN registration applies to you.
What happens if I should have STRN but don’t register?
FBR/provincial authorities can penalize unregistered businesses operating above the threshold, and you may owe back sales tax plus penalties once discovered.
