Sales Tax Registration Pakistan 2026 - STRN Guide

Sales tax registration (STRN — Sales Tax Registration Number) in Pakistan is mandatory for businesses above the threshold, and voluntary for others who want to claim input tax credits. This guide covers who must register, the step-by-step registration process, and how to file monthly returns.

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.

Frequently Asked Questions

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).
