What is Sales Tax Registration (STRN) in Pakistan?
Sales Tax Registration gives your business an STRN (Sales Tax Registration Number) also known as GSTIN or STRN. It authorizes you to collect 17% General Sales Tax (GST) on taxable supplies, claim input tax credit on purchases, and file monthly returns with FBR. The GST registered business is listed on the FBR ACTIVE taxpayer list for sales tax purposes.

Monthly GST Return Filing Obligations

- Sales (Output Tax): 17% GST collected from customers on taxable supplies
- Purchases (Input Tax): 17% GST paid to suppliers — claimable as credit
- Net payable: Output Tax minus Input Tax = Amount payable to FBR
Common GST Registration Rejections — Avoid These
- Utility bill not in business owner's name or at a different address
- Business premises not verifiable (virtual office not accepted)
- NTN not active or not filed for prior year
- Business bank account not yet opened
- Photographs of premises missing or unclear
After the STRN Is Issued
The first month after registration matters most. Set up invoice numbering that includes your STRN and the buyer's details, register your business bank account in the sales tax profile, and file the first monthly return even if you made no sales. Missing the first return is a common reason new registrations are suspended.
Frequently Asked Questions
Do I file a sales tax return in my first month even without sales?
Yes. A return is due every month from registration, including nil returns when there were no sales.
Can I register for GST before my business starts earning revenue?
Yes. Pre-registration is possible if you can show business setup (office, machinery, initial purchases). Pre-registration allows you to claim input tax on setup costs before your first sale. This is beneficial for manufacturers and importers with high initial capital expenditure.
What is the penalty for not registering for GST when required?
Failure to register when required makes you liable for all GST that should have been collected, plus a penalty of Rs. 10,000 per month of default under Section 33 of the Sales Tax Act. FBR can also impose additional penalty for tax evasion equal to the tax not paid.
What is the difference between GST and PRA/SRB registration?
GST on goods is administered by FBR (federal). GST on services is administered by provincial authorities: PRA for Punjab, SRB for Sindh, KPRA for KP, BRA for Balochistan, AJK Revenue for AJK. Many businesses need both FBR-STRN (for goods) and PRA/SRB registration (for services).
