Advance Receipt Voucher: GST Rules for Customer Advances

Advance receipt voucher rules under GST: when to issue, time of supply for advances, and how to settle against final invoice.

When an Advance Receipt Voucher Is Required

Section 31(3)(d) of the CGST Act requires a registered supplier to issue a receipt voucher when they receive an advance payment for a future supply. The voucher must be issued on the date of receipt of the advance — not at the time of the eventual invoice. This applies to both goods and services, though the time of supply rules differ between the two. Failing to issue a receipt voucher within the prescribed timeline is a procedural lapse that attracts penalty under Section 122.

Time of Supply for Advances

For services, the time of supply is triggered the moment advance is received, and GST liability arises immediately under Section 13(2). For goods, the government has notified an exemption — GST on advances is not payable for goods, only at the time of issuing the tax invoice — except for notified categories. This asymmetry creates a common compliance pitfall: service providers must pay GST on every advance, while goods sellers can defer until invoice. Always classify the supply correctly before deciding the timing.

Mandatory Fields on the Receipt Voucher

Rule 50 mandates the receipt voucher to include supplier name, GSTIN, address, serial number under 16 characters, date, recipient name and address, description of goods or services (even if tentative), the advance amount, applicable tax rate, CGST/SGST or IGST breakup, and place of supply. If the final tax rate or place of supply is unknown at the time of advance, the supplier can charge 18% as a default IGST rate and adjust later. The voucher is treated as a tax document, not a substitute for the invoice itself.

Settling and Refund Voucher

When the final tax invoice is issued, the advance is adjusted against the invoice value, and the net balance becomes the receivable. If the deal is cancelled or the supply doesn't happen, a refund voucher under Section 31(3)(e) and Rule 51 is issued, and the GST paid on the advance can be claimed back through GSTR-1 adjustments. The refund voucher must reference the original receipt voucher number for traceability. Without proper documentation, the GST paid on the cancelled advance becomes a sunk cost.
