What Is SST (Sindh Sales Tax) and SRB?
SST (Sindh Sales Tax) is a provincial tax imposed on services provided within Sindh under the Sindh Sales Tax on Services Act, 2011.
The tax is administered and collected by the Sindh Revenue Board (SRB).
If your business or profession falls under taxable services, registration with SRB is mandatory.
Key SST Tax Rates in Sindh
The current SST structure includes:
- Standard SST Rate: 15%
- Telecommunication Services: 19.5%
- Concessional Rates: Certain services qualify for reduced SST rates, providing relief to eligible businesses
Failure to register or charge SST correctly can lead to audits, penalties, legal notices, and reputational damage.
Waystax ensures your business is registered under the correct service category and tax rate, avoiding future complications.
