GST on Advance Received: Goods vs Services, Vouchers and Returns

GST on advance received is one of the most misunderstood rules for Indian suppliers. The short answer depends on what you supply: since 15 November 2017, regular taxpayers do not pay GST on advances received for goods, but GST is still payable on advances received for services, in the return for the period in which the money arrives. Getting it wrong either way is costly. Paying tax on goods advances blocks cash for no reason, while missing tax on service advances leads to interest and mismatches between GSTR-1 and GSTR-3B. This guide explains the time of supply rules, the receipt and refund vouchers you must issue, how to calculate tax on an advance, how to report and adjust it in returns, worked ₹ examples and the mistakes to avoid.

Why an Advance Can Trigger GST

GST is payable at the "time of supply". Section 12 of the CGST Act (for goods) and section 13 (for services) fix the time of supply as the earliest of certain events, and receipt of payment is one of them. Read on their own, both sections would make tax payable as soon as an advance reaches your bank account, before any invoice or delivery.

For goods, the government removed this effect through Notification 66/2017-Central Tax dated 15 November 2017. It provides that registered persons, other than those who opted for the composition levy, pay tax on outward supplies of goods at the time of invoice (the date of issue, or the last date by which the invoice should have been issued), not on receipt of an advance. For services there is no such relief, so section 13 applies in full: if the advance arrives before the invoice is issued, the advance is the trigger.

Note also that a refundable deposit is not treated as payment for the supply unless the supplier applies it as consideration. A security deposit for rented equipment that will be returned does not attract GST when received; it does when it is adjusted against the rent.

Goods vs Services at a Glance

Situation	GST on the advance?	When tax is paid
Advance for goods, regular taxpayer	No	When the invoice is issued or due
Advance for goods, composition taxpayer	The 2017 relief does not cover composition taxpayers	Confirm the current position with your CA
Advance for services	Yes	In the return for the period of receipt
Advance and invoice in the same tax period	Yes for services, but no separate advance entry needed	Reported through the invoice
Refundable security deposit	No, until applied as consideration	When it is adjusted against the supply

Typical service advances include annual maintenance contracts, software subscriptions, consulting retainers, event and venue bookings, training fees, construction milestones and advertising campaigns booked ahead.

How to Calculate GST on an Advance

An advance is treated as inclusive of tax. The formula is:

GST = Advance x Rate / (100 + Rate)

Example: a Bengaluru IT firm receives an advance of ₹5,90,000 from a client in Pune for an implementation project taxed at 18%.

• Taxable value = ₹5,90,000 x 100 / 118 = ₹5,00,000
• IGST (inter-state) = ₹5,90,000 x 18 / 118 = ₹90,000
• If the client were in Bengaluru, the same ₹90,000 would be split as CGST ₹45,000 and SGST ₹45,000

A common error is to apply 18% on top of the advance: ₹5,90,000 x 18% = ₹1,06,200, which overstates tax by ₹16,200.

Rule 50 of the CGST Rules covers two uncertain cases. If the rate of tax cannot be determined when the advance is received, tax is charged at 18%. If it cannot be determined whether the supply will be inter-state or intra-state, it is treated as inter-state.

Receipt Vouchers and Refund Vouchers

Receipt voucher

When you receive an advance for a supply, section 31(3)(d) requires a receipt voucher, not a tax invoice. Under rule 50 it should contain:

• Supplier name, address and GSTIN
• A consecutive serial number of up to 16 characters, unique for the financial year, and the date
• Recipient name, address and GSTIN or UIN, if registered
• Description of goods or services, amount of advance, rate of tax and amount of tax (CGST, SGST, UTGST, IGST, cess)
• Place of supply, with state name and code for inter-state supplies
• Whether tax is payable on reverse charge, and a signature

The format overlaps heavily with a tax invoice; see our guide to GST invoice mandatory fields. The recipient cannot claim input tax credit on a receipt voucher. Credit comes only with the tax invoice and receipt of the goods or services.

Refund voucher

If an advance is received and a receipt voucher issued, but no supply is made and no invoice is issued, section 31(3)(e) and rule 51 allow you to issue a refund voucher when the money is returned. It references the original receipt voucher and shows the amount refunded and the tax on it.

Adjusting the Advance in Returns

A hypothetical Hyderabad consultancy receives ₹2,36,000 on 18 March 2026 as an advance for a project taxed at 18% (intra-state). The work is completed and invoiced on 15 April 2026 for ₹5,00,000 plus GST.

• March: tax on advance = ₹2,36,000 x 18 / 118 = ₹36,000 (CGST ₹18,000 and SGST ₹18,000), paid through the March GSTR-3B.
• April: invoice tax = ₹5,00,000 x 18% = ₹90,000. Net additional tax = ₹90,000 minus ₹36,000 = ₹54,000.
• Balance due from the client = ₹5,90,000 minus ₹2,36,000 = ₹3,54,000.

Period	Event	Taxable value (₹)	GST (₹)	GSTR-1 table
March 2026	Advance received, no invoice	2,00,000	36,000	11A: advances received
April 2026	Tax invoice issued	5,00,000	90,000	4A: B2B invoices
April 2026	Advance adjusted	(2,00,000)	(36,000)	11B: adjustment of advances
April 2026	Net for April	3,00,000	54,000

In GSTR-3B, the outward supply figure for each month reflects the net position: the advance in March, and the invoice less the adjusted advance in April. Without the Table 11B entry, the ₹36,000 is paid twice.

When the order is cancelled

A client pays ₹1,18,000 in June for a training programme at 18%, and tax of ₹18,000 is paid in the June return. In August the programme is cancelled and the money returned. Issue a refund voucher in August and report the adjustment in Table 11B of the August GSTR-1, which reduces August's liability by ₹18,000. If there is not enough liability to absorb it, ask your CA about the refund route. Make such adjustments promptly; late ones are harder to defend in an audit.

When the rate changes in between

If the rate changes between the advance, the invoice and the supply, section 14 decides which rate applies based on the order of those events. Many businesses faced this around the rate changes of 22 September 2025. Work through such cases with your CA rather than assuming the old or new rate.

Accounting Entries

Keeping the customer ledger clean makes reconciliation easier. Using the Hyderabad example:

Event	Debit	Credit	Amount (₹)
Advance received	Bank	Customer account	2,36,000
Tax on advance	GST on advance (adjustment ledger)	Output CGST and SGST	36,000
Invoice issued	Customer account	Sales ₹5,00,000 and output CGST and SGST ₹90,000	5,90,000
Advance tax reversed	Output CGST and SGST	GST on advance (adjustment ledger)	36,000

After these entries the customer owes ₹3,54,000, the output tax ledgers carry ₹90,000 in total across the two months, and the adjustment ledger is back to zero. For income tax, the advance is a liability until the service is rendered; it is not income on receipt.

Common Mistakes and Interest Exposure

• Paying GST on goods advances as a regular taxpayer, which ties up cash for no reason.
• Missing tax on service advances, especially retainers, AMCs and annual subscriptions collected upfront.
• Applying the rate on top of the advance instead of treating it as tax-inclusive.
• Forgetting the Table 11B adjustment, so tax on the advance is paid again with the invoice.
• Issuing a tax invoice for the advance and another for the supply, which doubles turnover in GSTR-1.
• Not issuing a refund voucher when an advance is returned, leaving tax paid with no adjustment.
• Customers claiming credit on receipt vouchers, which is not allowed.

What a missed advance costs

If the ₹36,000 tax on the March advance is missed and paid only with the April return a month later, interest at 18% a year applies to the delayed tax: ₹36,000 x 18% x 30 / 365 = about ₹533. The amount is small, but repeated across many advances it adds up, and it creates a GSTR-1 trail that an officer can question. Our guide on GST late fee and interest shows the full calculation method.

Frequently Asked Questions

Is GST payable on advance received for goods?

Not for regular taxpayers. Since 15 November 2017, they pay tax on goods when the invoice is issued or due. The relief does not extend to composition taxpayers, who should confirm their position with a CA.

Is GST payable on advance received for services?

Yes. If the advance is received before the invoice is issued, tax is payable for the period in which the advance is received, and a receipt voucher must be issued.

What rate applies if the final rate is not known?

Under rule 50, tax is charged at 18% if the rate cannot be determined at the time of receipt, and the supply is treated as inter-state if its nature cannot be determined.

Can the customer claim input tax credit on an advance?

No. Credit is available only on a tax invoice and after receiving the goods or services, not on a receipt voucher.

Do I need to report an advance if the invoice is issued in the same month?

No separate advance entry is needed. Table 11A covers advances for which no invoice was issued in the same tax period; if both fall in one period, the invoice alone is reported.
