The deposit label does not decide the tax
For ordinary forward-charge services, a genuine security deposit is not treated as payment for the supply unless the supplier applies it as consideration: the proviso to section 2(31) is the key. An amount that is in substance advance service consideration cannot acquire protection merely because the receipt says “security”. Conversely, tax does not arise on an untouched, refundable security balance merely because the supplier holds cash. This analysis is current to 24 October 2026 and concerns deposit treatment; liability, exemption, reverse charge and place of supply of the underlying service require separate verification.
Read CGST Act section 2(31), section 13 and the valuation rules in ICAI’s April 2026 bare-law compilation. The deposit proviso determines when the amount becomes payment; section 13 determines the service time of supply. Neither permits an invoice or an earlier service trigger to be ignored.
Build the lifecycle from the contract
| Event | Question to resolve | Control response |
|---|---|---|
| Receipt as security | Is repayment genuine and is the amount unapplied? | Record a separately reconcilable deposit liability. |
| Change of purpose | Has the supplier applied an amount against service consideration? | Date and evidence the appropriation and test time of supply. |
| Settlement of an existing invoice | Was GST already recognised for that same supply? | Clear the receivable without duplicating output tax. |
| Retention or forfeiture | Is this service consideration, an agreed facility charge or genuine compensation? | Characterise the underlying obligation before deciding tax. |
| Refund | Is the balance still unapplied security or previously taxed consideration? | Use the correct refund and tax-document trail for the actual category. |
An appropriation can be taxable before the next bank receipt
A clear appropriation agreement, adjustment letter or operative contract term can show that the supplier has applied security toward a service. Do not wait for new money to arrive before reviewing GST. Equally, a unilateral journal headed “advance” does not establish that a disputed appropriation is contractually effective. Preserve the relevant terms and correspondence. For a genuine deposit later converted into an advance, analyse that conversion together with section 13; an earlier invoice or provision-of-service trigger may already have fixed liability.
Under section 13(2), timely invoicing brings the earlier of invoice or payment into the normal forward-charge test. If invoicing is late, the service-provision/payment test matters. The explanation also looks to the earlier entry in the supplier’s books or bank credit for receipt of payment. The original bank date of a genuine unapplied deposit is not automatically a service-advance date. Document why it was security at receipt and what changed subsequently.
Do not tax the same invoice twice
When a taxable invoice has already generated the proper liability, using deposit money to discharge that invoice changes the deposit and customer-receivable balances. It does not create a second identical supply. The working should show opening security, new security, amounts appropriated to identified invoices or advances, genuine compensation retained and refunds, ending with the closing balance. Match the underlying invoice’s taxable value and GST to the appropriation; do not assume every amount deducted is tax-exclusive.
Forfeiture requires a separate supply analysis
The CBIC Circular 178/10/2022-GST dated 3 August 2022 explains why damages or penalties for breach do not automatically represent a supply of tolerating an act. It also distinguishes arrangements that actually involve an agreed taxable service or facility. A security deduction for unpaid service charges, a contractual cancellation facility and compensation for physical damage can therefore produce different outcomes. Record what the retained money pays for. The circular is interpretive guidance; a “damages” ledger label is not decisive.
Refunds and documentation follow the amount’s history
A refund of untouched security reverses a liability; it does not by itself reverse taxable turnover or entitle anyone to ITC. If consideration was previously taxed, its cancellation or reduction needs the applicable invoice, voucher or credit-note procedure and conditions, not a deposit-refund journal. Receipt and refund voucher requirements for actual advances should be reviewed separately. No blanket form is prescribed here for all deposit movements.
The numerical cases assume the supplier is liable under normal forward charge, that the service is taxable and the specified combined 18% rate is independently verified for that fictional supply. They do not state a universal rate for rent, maintenance, residential occupation or all security arrangements. No rate change, cess or special valuation rule is assumed. Tax-inclusive amounts are separated using Rule 35; invoice amounts already assessed are not counted again.
Worked illustrations
These illustrations use fictional facts and expressly stated assumptions. Amounts are Indian rupees unless a different currency or unit is specified. They are independent examples, not findings about any actual client.
Illustrative example 1: Untouched refundable balance
A supplier receives ₹2,00,000 solely as repayable security, never applies it to consideration and later refunds all ₹2,00,000. Closing security is ₹2,00,000 − ₹2,00,000 = nil. Output GST from these deposit movements is nil. This does not remove GST on the service invoices paid separately.
Illustrative example 2: Partial appropriation as a new service advance
From genuine security of ₹2,00,000, the parties validly apply ₹59,000 as a tax-inclusive advance for a future service, with no earlier invoice or service trigger. At the assumed combined rate of 18%, value is ₹59,000 ÷ 1.18 = ₹50,000 and tax is ₹9,000. Unapplied security remains ₹1,41,000. Review the conversion date for time of supply rather than waiting for fresh cash.
Illustrative example 3: One transfer contains security and advance
A customer transfers ₹2,68,000: ₹1,50,000 genuine refundable security and ₹1,18,000 tax-inclusive service advance. The advance comprises value ₹1,00,000 and GST ₹18,000. Keep ₹1,50,000 in the security reconciliation. Treating the entire transfer as security would omit ₹18,000 assumed advance tax; treating it all as taxable consideration would overstate the payment base.
Illustrative example 4: Deposit settles a previously taxed invoice
A service invoice for value ₹1,00,000 plus ₹18,000 GST was issued on time and its liability correctly recorded. The supplier then applies ₹1,18,000 from security of ₹2,00,000 against that invoice. Security closes at ₹82,000 and the receivable at nil. Additional output GST from the settlement is nil; total GST for that invoice remains ₹18,000.
Illustrative example 5: Convert only the agreed part
A ₹10,00,000 security balance is partly converted into ₹3,54,000 tax-inclusive consideration for a future service, with no earlier tax trigger. Value is ₹3,00,000 and GST ₹54,000. The remaining ₹6,46,000 stays unapplied security. A subsequent refund of that ₹6,46,000 does not reverse the ₹54,000 tax on the applied portion.
Illustrative example 6: Damage compensation and an independent invoice
Assume evidence establishes that ₹25,000 retained from ₹1,00,000 security is genuine compensation for physical damage, with no independent bargain to tolerate damage and no service supplied for that sum. Refund is ₹75,000 and tax on that compensation is nil on these facts. An independently billed repair service or an amount actually adjusted against service dues requires its own analysis; the assumed result must not be copied to every forfeiture.

Sixteen practitioner FAQs
1. Does a receipt headed “deposit” postpone GST?
Only if it is genuinely a deposit rather than service consideration. The contract and actual use of the funds matter.
2. Must a genuine deposit always be refundable on demand?
Section 2(31) focuses on application as consideration. Contractual refund conditions and the economic purpose must be assessed; no universal on-demand condition is asserted here.
3. Is cash held for several years automatically consideration?
Holding duration alone is not the statutory application test. Check whether the facts still support security treatment and whether it was appropriated earlier.
4. Can a journal adjustment be a relevant event?
Yes, if it records an effective application as consideration. Support it with contractual authority and the actual facts, especially where the customer disputes the adjustment.
5. Is the original deposit bank date always the service tax date?
No. A genuine unapplied deposit is not payment for supply under the proviso. An earlier invoice or service trigger must nevertheless be checked.
6. What if an invoice predates appropriation?
Review whether tax already arose on that invoice. Clearing it from the security balance must not generate duplicate tax on the same consideration.
7. Can only part of the deposit become an advance?
Yes, where the facts support a partial application. Keep the remaining security and the applied consideration separately reconcilable.
8. Should GST be added to every deduction from security?
No. Determine whether the agreed deduction is tax-inclusive or tax-exclusive and whether it is consideration at all.
9. Does refunding untouched security require reversal of turnover?
No taxable turnover arose merely from that security receipt. A liability refund is different from cancelling previously taxed consideration.
10. Can the recipient claim ITC on a deposit receipt alone?
A security receipt does not by itself establish input tax or satisfy the statutory credit conditions. Review the actual taxable supply and prescribed documentation.
11. Are all forfeitures outside GST?
No. Characterise the arrangement. Agreed facility charges or adjustment against service consideration differ from genuine breach compensation.
12. Is compensation automatically a supply of tolerating damage?
The CBIC circular rejects automatic treatment. Examine whether there is an actual agreement constituting a supply for consideration.
13. Does this analysis cover reverse-charge rent without modification?
No. The worked timing cases assume normal forward charge. Reverse charge requires its own liability and timing review.
14. Is 18% a universal security-deposit rate?
No. A genuine unapplied deposit has no tax merely as a receipt. Any applied consideration follows the independently verified underlying service rate.
15. What if an advance is later cancelled?
Use the applicable advance, invoice and refund or credit-note procedure. Re-labelling the balance as security does not retrospectively erase an earlier liability.
16. What evidence best prevents duplicate tax?
A movement-level link from the security ledger to each invoice or advance, showing the original tax period, applied amount and remaining balance.
Conclusion
Reconcile what the money secures, when it is applied and whether the related supply has already been taxed. A deposit ledger supported by the contract and invoice history is more reliable than a blanket GST treatment for every receipt or forfeiture.
