GST on Retention Money, Security Deposit & Performance Guarantee

Quick answer: Is GST payable on retention money?

Retention money is not automatically a separate taxable event. The GST treatment depends on what the retained amount represents, how the contract is structured, when the supply is invoiced, and whether the amount is ultimately part of the consideration for the taxable supply.

Retention from an invoice?
If the full taxable supply has been invoiced, withholding part of the payment normally does not by itself postpone the GST liability on the invoiced consideration.

Refundable security deposit?
A genuine deposit held as security is not automatically consideration merely because money is received.

Forfeiture / deduction?
Do not automatically treat every deduction as a taxable service. First identify whether it is compensation for breach or consideration for an independent supply.

🟠 THE CONTRACT WORDING MATTERS“Retention”, “security deposit”, “performance security”, “LD”, “penalty” and “withheld amount” are not interchangeable GST concepts. Read the commercial purpose and the contractual trigger before deciding tax treatment.

1. Retention money, security deposit, performance guarantee and liquidated damages are different

Many GST disputes begin because four different commercial mechanisms are posted into one ledger called “retention”. The first control is therefore classification.

Item	Typical purpose	Does receipt itself mean taxable consideration?	Key GST question
Retention money	Part of contract consideration withheld until milestone, completion or defect-liability conditions.	Not merely because it is withheld/received.	Has the underlying supply been made/invoiced, and is the retained amount part of its consideration?
Security deposit	Security against contractual performance or obligations, normally refundable or adjustable under specified conditions.	Not automatically.	Is it genuinely security, or is it actually advance/payment for a supply?
Performance guarantee	Bank/corporate guarantee or cash security supporting performance obligations.	Depends on the actual transaction.	Is the guarantee fee a separate supply? What happens when it is invoked?
Liquidated damages	Contractual amount linked to delay, non-performance or breach.	Not automatically taxable as “tolerating an act”.	Is the amount compensation for breach or consideration for an independent supply?

Core principle: The label written in a work order is useful evidence, but GST treatment follows the substance and legal character of the transaction. CBIC's Circular 178/10/2022-GST explains that payments arising only as compensation for losses or breach are not automatically consideration for a supply; a separate analysis is needed where an independent supply of tolerating/refraining/doing something exists.

2. The GST decision: follow the money back to the underlying contract

The correct workflow is not “money received = GST”. Start with the underlying supply and then identify the contractual amount.

Read contract→Identify supply→Classify amount→Check invoice→Apply time of supply→Report GST

🟢 PART OF SUPPLY CONSIDERATIONIf the amount is simply a portion of the agreed price that is withheld and later released, analyse the underlying taxable supply. Withholding by the customer does not, by itself, convert the consideration into a different supply.

🔴 NOT AUTOMATICALLY A TAXABLE “SERVICE”A deduction because of delay, defective performance or breach is not automatically consideration for a separate service of “tolerating” the breach. The contractual facts must be examined.

Section 15 and valuation

Section 15 provides the basic framework for determining the value of taxable supply. For a normal transaction between unrelated parties where price is the sole consideration, the transaction value is the price actually paid or payable for the supply, subject to the statutory inclusions and exclusions.

Therefore, the accounts team should not create a GST rule merely from the cash-flow date. The commercial price, invoice and time-of-supply rules must be considered together.

3. Retention money in works contracts: the practical treatment

Retention is common in EPC, civil construction, infrastructure, engineering, fabrication, installation and maintenance contracts. A typical contract may certify work of ₹1 crore, with 5% retained until completion or the defects-liability period.

Scenario	Contract position	GST direction	Practical control
EPC contractor	₹1 crore work certified; 5% retained.	Generally analyse full certified consideration	Match RA bill, tax invoice, retention ledger and contract clause.
Customer releases retention later	₹5 lakh released after defect period.	Usually payment of earlier consideration, not a new supply	Do not create a second taxable supply merely because cash arrived later.
Retention is not yet earned	Amount is conditional on future certification and may never become payable.	Invoice/time-of-supply facts must be reviewed	Do not assume the same treatment as an already-invoiced amount.
Retention forfeited for contractual breach	Customer keeps the amount under a breach clause.	Analyse compensation vs separate supply	Review clause, trigger, accounting entry and settlement documents.

Important: There is a major difference between “5% of an invoice is withheld” and “5% is not yet part of the amount invoiced or payable because certification has not occurred.” The invoice, measurement certificate, contract and payment terms should be reviewed together.

4. Does retention money change the GST invoice value?

Suppose a contractor completes work valued at ₹10,00,000 plus GST of ₹1,80,000. The customer is contractually entitled to retain 5% of the contract consideration until the defect-liability period.

Particular	Amount	What the GST team should check
Work certified	₹10,00,000	Measurement/certification and contractual milestone.
GST @ 18%	₹1,80,000	Applicable classification/rate and place of supply.
Retention on value	₹50,000	Whether this is merely withheld from consideration.
Immediate commercial release	₹9,50,000 + applicable tax treatment	Payment timing does not automatically rewrite the taxable supply.
Later retention release	₹50,000	Track as settlement of the original commercial amount if that is what the contract provides.

ERP design tip: Keep separate fields for Gross Contract Value, Certified Value, GST, Retention Withheld, Net Paid, Retention Release Date and Retention Forfeited. Do not use a single “Outstanding” field for all of them.

5. Retention money is not the same as an advance

Situation	Commercial meaning	GST question	Control
Advance	Money paid before the relevant supply/payment milestone.	Apply the applicable time-of-supply rules and sector-specific provisions.	Maintain advance register and later adjustment.
Retention	Part of earned/certified consideration withheld by the customer.	Analyse the underlying invoice/supply and whether the amount is already part of the taxable consideration.	Link retention to the original invoice.
Security deposit	Refundable security against performance.	Receipt itself is not automatically consideration for a supply.	Track deposit liability separately.
Earnest money	Security/commitment amount under a contract.	Depends on whether it is refundable, adjusted against consideration or forfeited.	Track contractual trigger.

Do not build one generic “advance/retention” GST code. The same cash receipt can have a very different GST consequence depending on why it was paid and whether it is adjusted against the price of a supply.

6. Security deposits: when is a deposit outside the taxable value?

A genuine security deposit is generally held to secure performance and is expected to be refunded or adjusted according to the contract. The accounting entry alone does not decide GST.

Scenario	Likely analysis	Action
Refundable security deposit, separately documented	Not automatically consideration	Keep deposit agreement and refund/adjustment trail.
Deposit adjusted against final invoice	Becomes relevant to consideration/payment analysis	Map adjustment to the supply invoice.
Amount called “deposit” but non-refundable and actually payment for service	Substance may point toward consideration	Review commercial terms and invoice.
Deposit forfeited for breach	Analyse compensation vs consideration for an independent supply	Document the breach and contractual basis.
Deposit returned without adjustment	Normally a return of money	Reconcile bank and deposit liability.

7. Performance guarantees: bank guarantee, cash security and invocation

Performance security can appear in government contracts, EPC projects, supply contracts, maintenance contracts and long-term service arrangements. The guarantee itself and the underlying supply should not be mixed.

Guarantee fee
A bank or other service provider charging a fee for issuing a guarantee is a separate transaction that must be analysed on its own.

Cash performance security
Receipt may be a security arrangement rather than consideration, depending on the contract.

Invocation
Invocation can have consequences under the contract, but it does not automatically mean the recipient supplied a taxable “toleration” service.

Event	GST review question
Contractor gives bank guarantee to customer	Who supplied the guarantee service and who charged the fee?
Customer deducts performance security	Is it still a refundable security or has it become a contractual recovery/compensation?
Guarantee is invoked	Read the invocation reason and contractual clause; determine whether it is compensation for breach or consideration for another supply.
Guarantee amount is later refunded	Reconcile the reversal/refund to the security ledger and contract.

8. Liquidated damages, penalties and compensation: do not automatically charge GST

This is one of the most important practical distinctions in contract GST. A payment labelled “liquidated damages”, “penalty” or “compensation” can arise because one party breached the contract. That does not by itself prove that the other party supplied a service of tolerating the breach.

🔴 DO NOT USE THIS SHORTCUT“There is a payment under a contract, therefore it is consideration for a taxable service.” The contractual object and the actual reason for payment must be established.

Payment	Possible character	Practical GST approach
Delay damages for late completion	Compensation for loss/breach	Analyse under the contract and CBIC guidance; not automatically taxable.
Penalty for failure to meet specification	Compensation/price adjustment/breach consequence	Identify whether any separate supply exists.
Cancellation charge	May be linked to an agreed cancellation facility	Examine whether the payment is consideration under the contractual arrangement.
Fee expressly charged for allowing cancellation	Potentially consideration for a contractual facility	Analyse supply, agreement and applicable valuation.
Interest for delayed payment	Statutory valuation treatment may apply	Analyse separately under the GST valuation/time-of-supply provisions.

CBIC Circular 178/10/2022-GST: The circular distinguishes pure compensation for loss/breach from payments that are consideration for an independent activity such as tolerating an act, refraining from an act or doing an act. Use the actual contract and facts, not only the ledger description.

9. Forfeiture, deductions and set-off: three questions before booking GST

What was the original amount? Was it consideration, deposit, retention, advance or security?
Why was it deducted/forfeited? Payment default, delay, defective work, cancellation, commercial settlement or another reason?
Did anyone actually supply something in return? If yes, identify that supply and its value. If not, assess whether the amount is compensation rather than consideration.

Ledger description	Why it can mislead	Better internal description
Retention received	Could mean release of earlier withheld consideration.	Retention release against original invoice/contract.
Retention forfeited	Could be compensation or contractual recovery.	Forfeiture under clause + reason code.
Penalty income	Could be breach compensation or consideration for a separate facility.	Contractual compensation / independent supply assessment.
Security deposit	Could actually be an advance or non-refundable fee.	Refundable security / adjustable deposit / consideration.

10. Accounting and GST reconciliation: build a retention register

For project businesses, the most reliable method is to connect contract billing, GST invoices, retention, payments and release/forfeiture in one schedule.

Field	Purpose
Customer GSTIN	Correct recipient and place-of-supply control.
Project / contract number	Links billing to the underlying agreement.
RA bill / invoice number	Core GST document reference.
Certified value	Measurement/certification basis.
Taxable value	GST reporting base.
GST amount	Tax charged and reconciled to return.
Retention percentage	Contractual withholding.
Retention amount	Amount withheld against the invoice/contract.
Net cash received	Bank settlement amount.
Retention release date	Later cash settlement tracking.
Retention forfeiture	Separate contractual outcome.
GST treatment reason code	Prevents generic “retention” classification.

Recommended reason codes: RET-INVOICED, RET-NOT-YET-CERTIFIED, RET-RELEASED, RET-FORFEITED, SEC-REFUNDABLE, SEC-ADJUSTED, PG-INVOCATION, LD-COMPENSATION, LD-INDEPENDENT-SUPPLY-REVIEW.

11. GSTR-1 and GSTR-3B: how retention should flow

Returns should reflect the taxable supply and the applicable GST liability, not simply the bank receipt. The accounts team should reconcile the invoice population with the retention schedule.

Measurement / supply→Tax invoice→GSTR-1→GSTR-3B liability→Customer payment→Retention release

Situation	Return control	Common mistake	Better approach
Full invoice issued with retention withheld	Reconcile invoice and tax to GSTR-1/3B.	Reducing taxable value only because cash was withheld.	Check contract, invoice and applicable time-of-supply rule.
Retention released later	Track against original invoice.	Reporting a second sale merely because money was received.	Use the original invoice linkage.
Retention forfeited	Separate contractual event analysis.	Automatically issuing a GST invoice for “penalty income”.	Determine whether a separate taxable supply exists.
Security deposit returned	Reconcile deposit liability and bank.	Treating refund as negative turnover.	Keep it separate from taxable supply reporting unless contract facts require adjustment.

12. Recipient-side ITC: does retention affect the buyer's credit?

The recipient should reconcile the supplier invoice and the commercial payment separately. The existence of retention does not, by itself, decide whether ITC is available.

Invoice received?
Verify the tax invoice and supplier reporting.

Goods/services received?
Check actual receipt and business use.

Payment condition?
Separately monitor applicable payment-related ITC rules; do not confuse retention with a permanent ITC block.

For example, where a customer withholds 5% retention from a contractor's invoice, the GST team should not automatically classify the retained amount as “ITC not available”. The recipient's ITC analysis must follow the applicable statutory conditions, restrictions and payment rules.

Separate concepts: Supplier-side GST liability, recipient-side ITC eligibility and commercial payment/retention are three different control questions. They may be linked by the same invoice, but one should not be used as a shortcut for another.

13. 50+ practical retention, deposit and guarantee cases

15. 12 common mistakes in retention-money GST accounting

#	Mistake	Why it creates risk	Better control
1	GST charged only when retention is released	Cash timing may be confused with time of supply.	Start from invoice/supply and statutory time-of-supply rules.
2	Full invoice value ignored because cash received is lower	Creates books vs return mismatch.	Reconcile gross invoice and net settlement separately.
3	Every retention amount treated as an advance	Retention and advance have different commercial meanings.	Use separate ERP reason codes.
4	Every security deposit treated as taxable turnover	Genuine refundable security is not automatically consideration.	Review refund/adjustment terms.
5	Every penalty treated as taxable service	Compensation for breach is not automatically consideration for a separate supply.	Apply Circular 178 principles and contract analysis.
6	Retention release booked as fresh revenue	Can double-count turnover.	Link release to original invoice.
7	Forfeiture booked without legal note	Later review cannot establish why the amount was retained.	Keep clause, notice and settlement evidence.
8	Customer debit note accepted as GST document automatically	Commercial debit notes and GST documents have different roles.	Verify document type and tax effect.
9	Retention ledger not reconciled project-wise	Old balances remain unresolved.	Monthly project-wise ageing.
10	ITC payment conditions ignored	Recipient-side ITC can involve separate payment rules.	Run invoice/payment ageing independently.
11	Contract changes not shared with GST team	Commercial amendments can change billing/settlement.	Contract-change approval workflow.
12	One generic GST code for retention, LD and security	Destroys audit trail and legal classification.	Use distinct reason codes.

16. Frequently asked questions

Is GST payable on retention money?

Retention itself is not a separate GST category. If it is part of consideration for an underlying taxable supply, the GST treatment follows the supply, invoice and time-of-supply rules. Withholding payment does not automatically create a new tax point.

Does retention money become taxable only when it is released?

Not automatically. If the underlying supply has already been invoiced and the retention is simply withheld consideration, the later release is normally a payment event connected with the original supply rather than a second supply.

Is a security deposit taxable under GST?

A genuine refundable security deposit is not automatically consideration merely because money is received. If it is later adjusted against consideration or becomes non-refundable under the contract, analyse the actual transaction at that stage.

Is performance guarantee invocation taxable?

Invocation should be analysed from the contractual facts. It should not automatically be treated as consideration for a taxable service of tolerating an act.

Are liquidated damages taxable under GST?

Not every liquidated-damages payment is automatically taxable. CBIC Circular 178/10/2022-GST distinguishes compensation for breach from consideration for an independent supply.

Should retention be shown separately in GSTR-1?

Do not create a separate outward supply merely because a retention ledger exists. Reconcile the GST reporting to the underlying taxable invoice/supply and the applicable return requirements.

Does retention affect the buyer's ITC?

Retention is not itself a permanent ITC restriction. The recipient should separately test invoice validity, receipt, eligibility, restrictions and applicable payment-related conditions.

Can retention be released in the next financial year without additional GST?

The later financial-year release does not automatically create a new taxable supply. Link the payment to the original invoice and assess whether any original value or tax correction is required.

What if retention is forfeited?

Identify whether the amount is compensation for breach, recovery of costs, reduction of consideration or consideration for an independent supply. The contract and facts determine the analysis.

What is the biggest accounting mistake?

Using the bank statement as the GST source. For retention contracts, GST review needs the contract, measurement certificate, invoice, return, payment and settlement trail together.

KEY TAKEAWAY

Do not let the word “retention” decide the GST treatment

The correct sequence is: Read the contract → identify the underlying supply → classify the amount → check the invoice and time of supply → separate retention/security from compensation → report the actual taxable transaction → reconcile later release or forfeiture.

Contract→Supply→Invoice→GST→Payment→Retention→Release / Forfeit
