Section 57 of the Income-tax Act, 2025 — Revenue Recognition for Construction and Service Contracts (Percentage of Completion Method)

In plain language

What Section 57 says in plain English

Section 57 of the Income-tax Act, 2025 lays down how a business must recognise its taxable profit from construction contracts and service contracts. It answers a simple but crucial question: when a project runs across more than one financial year, in which year do you offer the profit to tax? The answer is the Percentage of Completion Method (POCM) — you book revenue and profit in proportion to the work actually completed each year, not in a lump sum at the end.

This section is the direct successor to Section 43CB of the old Income-tax Act, 1961 (which was inserted by the Finance Act, 2018). The rule itself is carried forward almost word-for-word; only the section number and the cross-reference have changed. The computation must follow the Income Computation and Disclosure Standards (ICDS) — specifically ICDS III (Construction Contracts) and ICDS IV (Revenue Recognition) — as notified under section 276(2) of the 2025 Act (the equivalent of the old section 145(2)).

Who does it apply to?

• Builders, real-estate developers and civil contractors executing construction contracts spanning multiple years.
• Infrastructure and EPC (engineering, procurement, construction) companies — roads, bridges, plants, pipelines.
• Service providers under long-duration contracts — IT projects, consultancy, AMC (annual maintenance), architects, project managers.
• Applies to all forms of business — individuals, firms, LLPs and companies — that compute income under the head "Profits and gains of business or profession".

The three permitted methods

• Percentage of Completion Method (POCM) — the default rule. Both construction contracts and service contracts are recognised as work progresses. Profit = (cost incurred to date ÷ total estimated cost) × total contract value, less costs already booked.
• Project Completion Method — for short service contracts. If a service contract lasts 90 days or less, the whole profit may be recognised on completion.
• Straight Line Method — for indeterminate service contracts. Where a service contract involves an indeterminate number of acts over a specified period (for example, a year-long AMC), revenue is spread evenly over the period.

Two anti-avoidance rules you must remember

• Retention money is part of contract revenue. Even the portion of the bill your client holds back until final handover (typically 5–10%) must be included in revenue when computing the stage of completion. You cannot postpone tax on retention money merely because it has not yet been received.
• Incidental income does NOT reduce contract cost. Interest, dividends or capital gains earned incidentally (say, on temporarily parked advances) cannot be netted off against project costs. Such income is taxed separately, usually under Income from Other Sources.

How it interacts with other provisions

• It works alongside the general computation rules for business income and the mandatory ICDS framework under section 276.
• Real-estate developers who sell flats/plots also watch the Guidance Note on Real Estate and stamp-duty-value rules; Section 57 governs the contract revenue, not the stock-in-trade sale of finished units.
• Since retention money is taxed on accrual, timing differences with GST and TDS (tax deducted by the contractee) commonly arise and must be reconciled.

Practical implications

• Reliable estimates are essential. POCM depends on estimating total contract cost accurately; poor estimates distort year-wise profit and invite scrutiny.
• Maintain a work-in-progress ledger and stage-of-completion certificates from engineers/architects to defend your computation in assessment.
• You cannot defer profit to the last year — this is the core reason the section exists, to prevent contractors bunching income at the end and manipulating tax across years.
