How to Calculate GST in Pakistan
FBR Compliant
Our GST calculator Pakistan uses the standard Sales Tax Act formulas to separate tax-inclusive and tax-exclusive amounts.
17% vs 18%
Calculate both the standard 18% GST (General Sales Tax) and specialized rates for retailers in Karachi, Lahore, and Islamabad.
Understanding Tax Inclusive vs Exclusive
When billing corporate clients in Rawalpindi or Faisalabad, you often need to decide whether your price already includes the government's share. If your price is Inclusive, the GST is "inside" the total. If it is Exclusive, the GST must be added on top of your service fee.
GST for Small Businesses
Most retail shops in Pakistan are now required to be Tier-1 integrated with the FBR (Federal Board of Revenue). This means every invoice must show the STRN (Sales Tax Registration Number) and a clear breakdown of the 18% tax. Using a free online tax tool prevents calculation errors during manual billing.
- STRN Requirement: Ensure your sales tax registration is active.
- Consumer vs Business: GST is usually paid by the end customer.
- Input vs Output: Offset your tax paid on purchases against tax collected from customers.
Automate Your Tax Filing
Manual tax calculations are time-consuming and prone to audit risks. BasiraSoft's SmartMart POS handles FBR integration natively, generating STRN-compliant receipts and calculating your monthly tax liability automatically.
