🇵🇰 MONTHLY FBR & PROVINCIAL COMPLIANCE
Sales Tax Return
Filing (Company)
Outsource your monthly sales tax return filing across FBR IRIS and provincial revenue authorities (PRA, SRB, KPRA, BRA). We reconcile input vs output tax, generate payment challans, and ensure error-free submissions on time.
What is Sales Tax Return Filing?
In Pakistan, having a Sales Tax Registration Number (STRN) requires you to file a detailed tax return every single month. This return matches every invoice you issued to clients against every invoice you received from registered suppliers.
Federal sales tax on goods is filed via the FBR IRIS portal, while sales tax on services is filed on provincial portals (PRA in Punjab, SRB in Sindh, KPRA in KPK, BRA in Balochistan). Each portal requires specific Annexure formatting and strict invoice reconciliation.
Core Return Elements
- Annexure C: Declares all sales invoices issued to buyers with NTN/STRN.
- Annexure A: Reconciles input tax from verified supplier invoices.
- Tax Payment Challan: Automatically calculates net payable amount for online payment.
- Final Acknowledgment: Formal proof of submission for your corporate audit records.
The Cost of Missing Monthly Returns
FBR and provincial revenue authorities use automated algorithms that instantly trigger penalties and blacklisting if deadlines are breached.
Automatic Heavy Fines
Section 33 of the Sales Tax Act imposes a statutory penalty starting at Rs. 10,000 per month for late filing, increasing for repeat defaults.
STRN Blacklisting
Unfiled returns lead to STRN suspension. Once suspended, your buyers cannot claim input tax on your invoices, destroying your B2B client relationships.
Lost Input Tax Claims
If you fail to adjust input tax within the statutory 180-day window, you forfeit your right to claim tax deductions permanently.
