The Federal Board of Revenue (FBR) has required registered taxpayers to issue sales tax invoices for advance payments received against future supplies. The procedures were notified through SRO 2063 of 2026.
Taxpayers must declare the output sales tax on an advance payment in the return for the tax period in which the amount is received. Each invoice must carry the particulars prescribed under Section 23 of the Sales Tax Act.
Why the New Requirement Matters for Pakistani Businesses
The move comes after years of concern from the tax administration that advance payments were often recorded without proper invoicing, leading to gaps in tax collection. By making invoices compulsory, the FBR aims to close the loophole that allowed some firms to defer tax liability until the final supply was delivered.
For businesses, the change means an additional step in the cash-receipt process. Companies will need to generate a sales tax invoice at the moment they receive any pre-payment, even if the related goods or services will be delivered months later. The invoice must be filed electronically through the FBR's online portal, where it will be linked to any subsequent invoices for the same transaction.
How the New Procedure Works
Under the new rules, the taxpayer must first issue an advance-payment invoice that meets the specifications of Section 23. The invoice must include the taxpayer's registration number, the date of receipt, a description of the future supply, the amount received, and the applicable sales tax rate at the time of receipt.
When a taxpayer receives multiple advance payments against a single supply, a separate invoice must be issued for each payment. Each invoice must be electronically linked to the earlier ones to ensure complete traceability.
When the actual supply is made, the taxpayer must issue a final sales tax invoice that references the relevant advance payment invoices. The value and tax already accounted for on advance payments will not be counted again. Sales tax on any outstanding amount will be calculated only on the remaining value of the supply.
Tax Rate Application on Advance Payments
The FBR has clarified that advance payments will be taxed at the rate in force when they are received. Any remaining amount will be taxed at the rate applicable on the date of the actual supply. This dual-rate approach prevents double taxation while respecting changes in tax policy that may occur between the time of receipt and delivery.
For example, if a 17% rate applies when a customer pays an advance in January, but the rate rises to 19% by the time the goods are shipped in June, only the advance portion remains taxed at 17%. The balance of the invoice will be taxed at 19%.
Adjustments for Changes, Refunds, or Cancellations
The rules also provide for adjustments where advance payments or the value of supplies are increased, reduced or refunded, or where supplies are cancelled in whole or in part. These adjustments will be made under Section 9 of the Sales Tax Act and Rules 19 to 22.
In practice, if a contract is renegotiated and the total price is reduced, the taxpayer must issue a credit note for the excess advance amount. The credit note must also be electronically linked to the original advance invoice, and the corresponding tax adjustment must be reflected in the next tax return.
Electronic Linking and Record-Keeping Obligations
Taxpayers must also electronically link and maintain all advance payment invoices, debit and credit notes, and final sales invoices in the prescribed manner. This is intended to ensure proper identification and cross-referencing of each transaction.
The FBR's online system generates a unique identifier for every invoice. When a final invoice is uploaded, the system prompts the user to select the related advance invoices. The linkage creates an audit trail that can be inspected by tax officers in real time.
Impact on Different Sectors
Manufacturing firms that often receive large pre-payments for custom orders will need to adjust their ERP systems to auto-generate the required invoices. Service providers, especially in construction and engineering, will see similar changes because projects are frequently funded through staged payments.
Small and medium enterprises (SMEs) may face a steeper learning curve, as many still rely on manual bookkeeping. The FBR has announced a series of webinars and printed guides to help these businesses comply.
What Businesses Should Do Now
1. Review internal cash-receipt procedures and ensure that an invoice is created at the moment an advance is recorded.
2. Update accounting software to capture the mandatory fields of Section 23 and to generate the electronic link code.
3. Train finance staff on the new filing timeline - the advance-payment invoice must be submitted in the same tax period the cash is received.
4. Prepare for possible adjustments by keeping detailed records of any changes to contract values, refunds, or cancellations.
What Comes Next
The FBR has indicated that compliance will be monitored through its regular audit program. Taxpayers who fail to issue the required invoices or who do not correctly link them may face penalties under Section 120 of the Sales Tax Act.
While the exact enforcement schedule has not been published, the board typically allows a three-month grace period after a new rule is issued before initiating audits. Businesses should therefore treat the requirement as effective immediately and act accordingly.
Future updates may refine the electronic linking process or adjust the thresholds for mandatory invoicing. Stakeholders are advised to keep an eye on subsequent SROs and FBR circulars.
The revised procedure sets out how sales tax is to be accounted for on advance payments, while ensuring the same amount is not taxed again at the time of the final supply.
