GST on Advances, Deposits & Refundable Security Deposits

Quick Answer: Does Every Deposit or Advance Attract GST?

No. The first question is not “Has money been received?” The first question is what the money represents under the contract and the GST law.

AdvanceMoney received towards a supply. For services, receipt of advance can trigger time of supply under Section 13. For goods, registered suppliers are generally exempted from paying GST merely on receipt of advance by Notification 66/2017-Central Tax.

Refundable depositA genuine deposit is not consideration merely because cash has been received. Section 2(31) specifically says a deposit is not payment for the supply unless the supplier applies it as consideration.

Appropriated depositOnce a deposit is actually applied against consideration for a taxable supply, the GST analysis changes because it can then form part of the value/payment for that supply.

Practical ruleDo not label every receipt as “advance”. Read the agreement, identify the purpose of the amount, check whether it is refundable, and determine whether it can be used only against a future supply.

Important: CBIC's sectoral FAQ states that a deposit given in respect of a supply is not considered payment for that supply unless the supplier applies it as consideration. The same FAQ distinguishes this from advances, for which service time-of-supply rules can apply from the date of receipt. citeturn0search1turn0search4

1. Legal Framework

The treatment of advances and deposits is spread across the CGST Act, the CGST Rules and specific notifications. The key provisions are:

Provision	Why it matters
Section 2(31)	Defines consideration and contains the specific proviso dealing with deposits.
Section 7	Determines whether there is a supply on which GST can arise.
Section 12	Time of supply of goods.
Section 13	Time of supply of services; receipt of payment is important for advances.
Section 15	Determines value of taxable supply, including amounts that form part of consideration.
Section 31(3)(d)	Requires a registered person receiving advance payment to issue a receipt voucher.
Section 31(3)(e)	Provides for refund voucher where a receipt voucher was issued but no supply is made and no tax invoice is issued in pursuance thereof.
Rule 50	Prescribes particulars of a receipt voucher.
Rule 51	Prescribes particulars of a refund voucher.
Notification 66/2017-Central Tax	Exempts registered taxpayers from payment of tax on advances received in case of supply of goods.

CBIC's notification listing confirms Notification 66/2017-Central Tax dated 15 November 2017 as the notification exempting taxpayers from payment of tax on advances received for supply of goods. citeturn0search0

2. Advance vs Deposit vs Consideration

This classification is the foundation of the entire article.

Question	Advance	Refundable deposit	Consideration/payment
Why is money received?	To be adjusted against a future supply	Security/protection against contractual risk	Payment for supply already made or becoming payable
Normally refundable?	Yes, if supply is cancelled subject to contract	Yes, if contractual conditions are satisfied	Normally no, because it pays for supply
Can it be adjusted against invoice?	Yes	Only if contract permits later appropriation	Already represents consideration
GST timing	Depends on goods/services and applicable time-of-supply rules	Generally not merely because it is received	As determined by applicable time-of-supply rules

Contract wording mattersA document calling an amount “security deposit” does not by itself settle the GST position. The commercial substance, refundability, contractual rights and how the amount is ultimately dealt with must be examined.

3. Advances Received for Goods

For goods, the practical position is different from the general service rule because Notification 66/2017-Central Tax exempts registered taxpayers from payment of tax on advances received in case of supply of goods. Therefore, a registered supplier of goods does not generally discharge GST merely because a customer paid an advance before the invoice/supply.

Example – machinery orderA company receives ₹10,00,000 advance on 20 September for machinery to be supplied in October. If the amount is genuinely an advance towards goods, the supplier does not pay GST merely on receipt of the advance under the notified exemption. GST is accounted for according to the applicable time of supply for the goods.

Do not overgeneralise:This goods-specific treatment should not be copied to service contracts. Services have a separate time-of-supply framework under Section 13.

4. Advances Received for Services

For services, receipt of advance can be critical because Section 13 determines time of supply using, among other things, the date of receipt of payment. The exact result depends on the statutory conditions and invoice timing.

Example – consultancyA consultancy firm receives ₹5,00,000 on 10 September as an advance for a taxable consulting assignment. If the amount is an advance towards the service, the supplier must examine Section 13 and account for GST at the applicable time of supply.

What if the service invoice is raised in the same tax period?

CBIC's FAQ explains that where an invoice is issued against an advance in the same tax period, the advance need not be separately reported as a separate advance in GSTR-1; the invoice details can be uploaded. Where advances remain against which invoices have not been issued at the end of the tax period, the prescribed reporting mechanism applies. citeturn0search4

5. Receipt Voucher – What to Issue When an Advance Is Received

Section 31(3)(d) requires a registered person who receives advance payment with respect to a supply to issue a receipt voucher or prescribed document evidencing receipt.

Rule 50 specifies particulars including supplier details, serial number, date, recipient details where applicable, description of goods/services, amount of advance and tax details. CBIC's invoice-rule page lists these particulars. citeturn0search3

Control	What the accounts team should capture
Receipt reference	Unique receipt voucher number and date
Customer	Name, address and GSTIN/UIN where applicable
Supply	Description and relevant contract/order reference
Tax	Taxable amount, rate and CGST/SGST/IGST details where applicable
Linkage	Customer advance ledger + contract + eventual invoice

6. Refundable Security Deposits

A refundable security deposit is commonly collected in construction contracts, rentals, equipment hire, dealership arrangements, utilities and service contracts. The starting point is Section 2(31): a deposit given in respect of a supply is not considered payment for that supply unless the supplier applies the deposit as consideration.

Typical genuine security depositCustomer pays ₹10 lakh as refundable performance/security deposit. Contract says it will be returned after satisfactory completion and settlement of contractual obligations. If it remains a security and is not applied as consideration, mere receipt should not be treated as a taxable supply merely because money changed hands.

When the position changesIf the supplier later appropriates ₹2 lakh of the deposit against a taxable invoice or contractual consideration, the appropriated amount must be analysed as payment/consideration for the relevant supply at that stage.

Maintain a separate deposit ledger

Do not mix customer advances and refundable deposits in one ledger. A separate ledger makes it easier to prove that the deposit was refundable, not consideration.

7. Earnest Money & Performance Security

Earnest money is frequently seen in tenders and contracts. Performance security is normally designed to protect the recipient of the contract against non-performance. GST treatment depends on whether the amount remains a deposit/security or is eventually appropriated towards consideration, damages or another contractual charge.

Performance security retained and refundedKeep evidence of the contractual security purpose, refund conditions and actual refund.

Security appropriatedIdentify exactly why it was appropriated. It may become relevant to consideration or another taxable event depending on the contract and circumstances.

CBIC's Circular 178/10/2022-GST also discusses situations involving retention or forfeiture of security deposits/earnest money in cancellation contexts, and says the treatment must be examined in the context of the contracted supply. citeturn0search10

8. Retention Money

Retention is common in infrastructure, EPC and works contracts. A customer may withhold a percentage of each running bill and release it after completion, defect-liability periods or other contractual milestones.

Do not confuse retention with advance.Retention is generally an amount withheld from consideration otherwise billed. The GST timing cannot be decided merely by looking at when the retained amount is eventually paid. The supplier must apply the time-of-supply and invoice rules to the underlying supply and contract.

Example: RA bill ₹1 crore, with ₹5 lakh retained until completion. The accounts team should track the ₹5 lakh as retention receivable under the contract and separately monitor the GST implications of the underlying taxable supply.

9. Mobilisation Advances in Construction & EPC Contracts

Mobilisation advances are common in large construction, mining, road, irrigation and EPC contracts. The label alone does not answer the GST question. Determine whether the payment is an advance towards taxable services, a refundable security, or another contractual amount.

Contract feature	GST analysis to perform
Advance adjustable against future RA bills	Strong indicator that the amount is an advance towards the contracted service; examine Section 13 and applicable invoice/tax timing.
Separate refundable security with no automatic adjustment	Analyse as deposit/security under Section 2(31).
Advance recovered from every RA bill	Maintain an advance-adjustment schedule linking each recovery to the original receipt.
Advance refunded on termination	Check tax already discharged, receipt/refund documentation and return adjustment/refund mechanism.

Best control: Maintain an advance register with contract number, receipt date, amount, GST paid, receipt voucher, RA-bill adjustment, balance and refund/closure date.

10. Refund, Adjustment & Forfeiture

Advance subsequently refunded

If an advance was received and later the supply does not happen, the tax and documentation consequences need to be traced. Section 31(3)(e) provides for a refund voucher where a receipt voucher was issued but subsequently no supply is made and no tax invoice is issued in pursuance thereof. CBIC also states that a refund voucher is for the full value of the advance, including GST. citeturn0search2turn0search4

Advance adjusted against invoice

When the supply occurs and an invoice is issued, the advance should be linked to the invoice and the tax already accounted for should be appropriately adjusted so that GST is not duplicated.

Deposit forfeited

Forfeiture needs a separate analysis. Do not automatically assume “forfeited = taxable” or “forfeited = outside GST”. Determine why the amount was retained and whether it represents consideration for a contracted facility/supply, compensation, penalty, damages or another payment. CBIC's Circular 178/10/2022-GST provides specific discussion for cancellation-related forfeitures. citeturn0search10

11. Deposits in Lease / Rent Arrangements

Security deposits under leases and rentals require careful contract review. A genuinely refundable, interest-free security deposit that is not consideration is different from rent paid in advance or a deposit that is contractually adjusted against rent.

Refundable securityTrack separately and document refund conditions.

Rent paid in advanceAnalyse as payment towards the leasing service and apply the relevant time-of-supply rules.

If a deposit is later applied against unpaid rent or other taxable consideration, the accounting and GST trail should clearly show the date and reason for appropriation.

12. Inter-company Deposits

Inter-company balances can be especially confusing where entities are related or are distinct persons for GST purposes. Do not classify a transfer as an “advance” merely because one group company transfers money to another.

Ask three questions: Is there an identified supply? Is the payment consideration for that supply? Is the recipient a related/distinct person whose transaction can be covered by Schedule I even without consideration?

For group-company balances, retain the agreement, purpose of funding, invoices, GSTIN mapping, ledger narration and settlement trail. A financing or funding arrangement should not automatically be converted into a supply of goods/services merely because the entities are in the same group.

13. Accounting & Documentation

GST compliance becomes much easier when the accounting system distinguishes each type of receipt.

Ledger	Purpose	Key document
Customer Advance	Future supply consideration	Contract/PO + receipt voucher + invoice linkage
Security Deposit	Refundable security	Agreement + deposit clause + refund/appropriation evidence
Retention Receivable	Contractual withholding from billed amount	RA bill + contract + completion certificate
Mobilisation Advance	Project advance	Work order + advance request + receipt voucher + RA adjustment
Earnest Money	Tender/contract security	Tender terms + security receipt + refund/forfeiture record

GST record rules require maintenance of accounts and relevant documents, and specifically require a registered person to maintain a separate account of advances received, paid and adjustments made thereto. citeturn0search5

14. GSTR-1 & GSTR-3B Treatment

GSTR-1

CBIC's FAQ explains that where an advance is received and the invoice is issued in the same tax period, the invoice can be reported rather than separately reporting the advance. Advances outstanding against which invoices have not been issued at the end of the tax period are reported through the applicable advance reporting mechanism, with later adjustment when the invoice is issued. citeturn0search4

GSTR-3B

The tax liability arising from the applicable time of supply must flow into the relevant outward-supply liability. A separate internal reconciliation should connect the advance register with the return liability and subsequent invoices.

Bank Receipt→Advance/Deposit Classification→Receipt Voucher→GST Liability if applicable→Invoice→Adjustment

17. Common Mistakes

Mistake 1: Calling everything a depositMoney received against a future service can still be an advance even if the ERP ledger says “deposit”.

Mistake 2: Applying service rules to goodsGoods advances have a specific exemption from payment of tax under Notification 66/2017.

Mistake 3: Ignoring appropriationA refundable deposit can change character when it is actually applied as consideration.

Mistake 4: No invoice linkageOld advances without a customer-wise reconciliation create avoidable GST and audit issues.

Mistake 5: Treating forfeiture automatically as taxableForfeiture must be analysed according to the contractual arrangement and nature of the payment.

Mistake 6: Ignoring retentionRetention is a contract/payment issue and should not be treated as a simple “advance pending invoice”.

19. FAQs

1. Is every advance taxable immediately?No. The answer depends on whether the supply is goods or services and the applicable time-of-supply rules. Goods advances have a specific exemption from payment of tax under Notification 66/2017.

2. Is a refundable security deposit taxable merely on receipt?Generally, a genuine deposit is not consideration merely because it is received. Section 2(31) specifically addresses this.

3. What if the deposit is later adjusted against an invoice?Analyse the amount as it is applied as consideration and link the appropriation to the underlying supply.

4. Is mobilisation advance always taxable?Not automatically. First determine whether it is an advance for a taxable service or a genuine refundable security.

5. Is retention money an advance?No. Retention is generally an amount withheld from contractual consideration and should be analysed separately from advances.

6. Is earnest money always outside GST?No blanket conclusion should be made. The reason for retention/forfeiture and the contractual supply must be examined.

7. What document is issued for advance?A receipt voucher is prescribed under Section 31(3)(d), subject to the statutory conditions.

8. What if no supply is ultimately made after an advance?Section 31(3)(e) provides for a refund voucher where the specified conditions are met, and the tax already accounted for must be reconciled appropriately.

9. Should advances and deposits use separate ledgers?Yes. Separate ledgers and registers materially improve audit trail and reconciliation.

10. Can a deposit become taxable later?The deposit itself is not automatically taxable merely because received, but when it is applied as consideration, the underlying supply and applicable GST provisions must be examined.

Key Takeaway

The safest GST approach is to stop treating every receipt as the same. Advance, refundable deposit, retention, earnest money, mobilisation advance and consideration are commercially different concepts. The GST result follows the legal and contractual character of the amount.

Read the contract→Classify the receipt→Check Sections 7/12/13/15→Issue correct document→Report correctly→Reconcile to final invoice/refund

For large businesses, especially construction, infrastructure, EPC, leasing and project-based organisations, an advance/deposit register linked to the GST return and invoice register is one of the simplest controls for preventing duplicate tax, missed tax and unexplained customer balances.
