Recognise the claim in the year certainty is achieved
Under section 278(2) of the Income-tax Act, 2025, a contract price escalation claim is income of the tax year in which there is reasonable certainty of realisation. Identify the part supported by the evidence and the date that evidence first supports it. Raising an invoice, making a journal entry and receiving cash are three different events; any one may help prove the position but none is the statutory test. This guide concerns tax year 2026–27, beginning 1 April 2026. For FY 2025–26 (AY 2026–27), apply the 1961 Act, including section 145B(2), which also used the reasonable-certainty test for escalation claims. Reconcile earlier inclusions under the applicable transition provisions.

Break the claim into amounts the evidence can support
Separate the base contract price from escalation, and divide escalation by work certificate, approved index, eligibility period and disputed component. Read the contract for notice requirements, the index reference date, excluded inputs, caps, eligible quantities and who can certify them. An approved price formula may establish how to measure a claim without showing that the disputed quantity will be paid. Equally, a dispute over one tranche need not delay recognition of another independently supported tranche.
Identify what changed at year-end
Keep dated records of the positions on both sides. A signed certificate from the authorised counterparty, binding settlement or evidence of partial payment can strengthen the case, but read reservations and payment conditions before drawing a conclusion. If an April letter merely confirms facts already established in March, test the March position. If the letter supplies a substantive approval missing at year-end, record the new event and the reason March evidence was insufficient. For an older contract with amounts already taxed under the prior Act, identify those amounts by work item before bringing any balance into a new tax year.
Reconcile claim by claim from the books to the computation
Start with escalation income credited in the year and compare it with escalation taxable in the year. Add current taxable escalation outside current book income and deduct book escalation already taxed or properly deferred under the section, after checking the legal basis and prior computations. Match cash collected to the claim ID and prior tax working. Review short receipts and later reductions separately; a bank difference alone does not establish that an earlier tax position can be reversed.
Six worked illustrations
All facts and amounts are fictional. Calculations illustrate the stated assumptions, not a predetermined legal outcome.
Illustrative example 1: Two supported amounts
A road contractor claims ₹36 lakh. The engineer with contractual authority certifies ₹24 lakh by 31 March 2027; ₹12 lakh remains subject to a genuine index dispute and has no other support. On the assumed facts the tax-year inclusion is ₹24 lakh and the open balance is ₹12 lakh.
Illustrative example 2: Escalation formula and cap
Eligible work is ₹400 lakh and the applicable escalation factor is 6%, giving ₹24 lakh before the ₹20 lakh cap. If reasonable certainty exists for the capped amount, use ₹20 lakh; the ₹4 lakh excess is outside the contractual entitlement on these facts.
Illustrative example 3: One contract over two tax years
A ₹30 lakh claim has ₹18 lakh supported by 20 March 2027; a substantive settlement in May 2027 supports the remaining ₹12 lakh for the first time. Allocate ₹18 lakh to tax year 2026–27 and ₹12 lakh to 2027–28.
Illustrative example 4: Tax ahead of book income
A manufacturer’s supply-price claim becomes reasonably certain for ₹15 lakh in tax year 2026–27. Its accounting ledger contains ₹9 lakh of that escalation for the same period. The upward adjustment for this item is ₹6 lakh; the total tax inclusion is ₹15 lakh. This assumes the ₹9 lakh book credit is included in the starting profit and no part was previously taxed.
Illustrative example 5: Books ahead of tax
A contractor credits ₹22 lakh of escalation in its books, but the evidence supports reasonable certainty only for ₹16 lakh by year-end. The illustrative downward tax bridge is ₹6 lakh, with that ₹6 lakh tracked for future review. This does not endorse the book accounting.
Illustrative example 6: Cash collected after inclusion
Of ₹28 lakh previously included in taxable income, ₹21 lakh is collected this year and posted against the receivable. Collection of the already taxed amount does not create a second inclusion on these facts; ₹7 lakh remains open in the collection ledger. A later interest component or separate claim would need its own analysis.

Sixteen practitioner FAQs
1. Does signing the original contract trigger tax on all future escalation?
No. Test the claim and its realisation evidence as the relevant work and pricing events arise.
2. Is a debit note conclusive evidence?
It shows what was asserted. Confirm entitlement, quantity and the counterparty’s position.
3. Can I defer until the bank receipt?
Only if the evidence actually supports that timing; the test is reasonable certainty, which can precede receipt.
4. Is a later retention release automatically new escalation income?
No. Identify the underlying claim and check whether its amount was already included.
5. Does customer silence equal approval?
Read the contractual procedure and relevant correspondence. Silence alone is weak evidence without more.
6. What if the customer agrees only to the formula?
Check eligible work and the amount. Formula approval does not resolve all measurement disputes.
7. How do I handle an index correction?
Recompute affected tranches using the contractual index source and document when the corrected facts became available.
8. Do I move the base contract price into this rule?
This analysis covers the escalation claim. Evaluate base consideration under its applicable rules.
9. What if the contract allows escalation only after formal notice?
Keep evidence of compliance with the notice condition or its valid waiver before relying on entitlement.
10. Can certification be withdrawn?
Check the contract and the terms of the certificate; record any reservation or unresolved condition.
11. What if a notice claims more than the signed cap?
Reconcile claimed, contractually supportable and taxable amounts separately.
12. Can a portfolio-level recovery probability replace the claim file?
It may inform review but does not establish the evidence for each material escalation tranche.
13. What if the adjustment was first booked after the tax return?
Review which facts existed in the relevant tax year and use the correction route applicable to the facts and stage.
14. How should I handle the 1 April 2026 transition?
Trace the earlier law and actual prior-year treatment before applying section 278(2) to the new tax year.
15. Does section 278(2) also mention export incentives?
Yes. This workflow addresses contract price escalation; incentive entitlement and its evidence require a separate analysis.
16. Which document best prevents double inclusion?
A claim-level history tying each taxable tranche to the exact prior computation and later collection.
