Sales Tax Registration (STRN) is mandatory for businesses supplying taxable goods or services in Pakistan once their annual turnover exceeds the prescribed threshold. Without STRN, you cannot issue valid sales tax invoices — which means corporate clients and large businesses cannot buy from you and claim input tax credit. This guide explains everything for 2026.
Who Must Register for Sales Tax?
- Manufacturers with annual turnover above PKR 10 million
- Importers of any value
- Retailers integrated with FBR’s Point of Sale (POS) system
- Service providers in specified sectors (IT, consulting, restaurants, hotels, advertising)
- Any business supplying taxable goods above the threshold
