ICDS III, IV and VII: Construction Contracts, Revenue and Government Grants

Updated 11 October 2026 · Fact-checked

ICDS III taxes construction contracts on the percentage of completion method. ICDS IV sets when revenue from sales, services, interest, royalties and dividends is recognised. ICDS VII decides when a government grant is income. To solve a question, identify the standard, find the stage of completion or recognition point, then compute the income for the year.

Understand ICDS III, IV and VII: Construction Contracts, Revenue and Government Grants

ICDS are standards notified for computing business income and income from other sources. They override the books of account where they differ. So the tax profit may not match the accounting profit.

Construction contracts (ICDS III). Under section 57(1) of the Income-tax Act, 2025, profits from a construction contract or a service contract are determined on the percentage of completion method, as per the notified ICDS. You recognise revenue and cost each year in proportion to the work done, not only when the contract ends. Section 57(2) adds two exceptions for service contracts: the project completion method if the contract lasts not more than ninety days, and the straight line method if the contract involves an indeterminate number of acts over a specified period.

Section 57(3) fixes two points. Contract revenue includes retention money. Contract costs are not reduced by incidental income such as interest, dividends or capital gains. Both points are favourite exam traps.

Revenue (ICDS IV). Revenue from sale of goods is recognised when the seller transfers property in the goods to the buyer for a price, or when all significant risks and rewards of ownership pass. Service revenue follows the percentage of completion method (or the exceptions above). Interest accrues on a time basis, royalty accrues as per the agreement, and dividend is income when the right to receive is established. Unlike AS 9, ICDS has no general rule that lets you defer revenue because of uncertainty of collection. Uncertainty is not a ground to postpone recognition, but you may claim a bad debt deduction when it is written off.

Government grants (ICDS VII). A grant is recognised only when there is reasonable assurance that you will comply with its conditions and that you will receive it. Then the treatment depends on the purpose. A grant for a depreciable asset reduces the asset's actual cost or written down value. A grant relating to a non-depreciable asset that requires fulfilment of certain obligations is recognised as income over the period that bears the cost of meeting those obligations. A grant given as compensation for expenses or losses already incurred is income in the year it becomes receivable. Other grants are income in the year of receipt, as the standard provides.

Key rules to remember

Stage of completion (cost method)
Stage of completion % = Costs incurred to date ÷ Total estimated contract cost × 100
Use costs that reflect work done. Costs for future work, such as advance payments to suppliers, are excluded from the numerator.
Revenue recognised in the year
Revenue for year = (Stage of completion % × Total contract revenue) − Revenue recognised in earlier years
Total contract revenue includes retention money (section 57(3)(a)).
Profit for the year
Profit = Revenue for the year − Contract costs for the year
Do not reduce costs by incidental interest, dividend or capital gains (section 57(3)(b)).
Service contract exceptions
Duration ≤ 90 days: project completion method. Indeterminate acts over a specified period: straight line method. Otherwise: percentage of completion.
From section 57(2).
Grant for depreciable asset
Revised actual cost or WDV = Cost or WDV − Grant
Depreciation is then computed on the reduced value.

How to solve ICDS III, IV and VII: Construction Contracts, Revenue and Government Grants questions

Use this order for any question on contracts, revenue or grants.

  1. 1Identify the standard: a construction or service contract (ICDS III), sale, interest, royalty or dividend (ICDS IV), or a grant (ICDS VII).
  2. 2For a contract, check the duration and nature. Choose percentage of completion, project completion (up to 90 days) or straight line.
  3. 3Compute total contract revenue, including retention money, and total estimated cost.
  4. 4Find the stage of completion from costs incurred to date. Exclude costs for future work.
  5. 5Compute cumulative revenue, then subtract revenue of earlier years to get this year's revenue. Deduct this year's cost, with no netting of incidental income.
  6. 6For sales, interest or grants, fix the recognition point and the year of taxation. For a grant, decide if it relates to a depreciable asset, a non-depreciable asset, or past expenses.
  7. 7State the final taxable figure and any adjustment to book profit.

Quickest way: Three-line contract workings

When to use it: Use for numerical questions with multi-year contracts and limited time.

  1. Write: Revenue, Cost to date, Estimated total cost.
  2. Compute % = Cost to date ÷ Estimated total cost, then cumulative revenue = % × contract price.
  3. Subtract earlier revenue and earlier cost to get the year's figures. Then restore contract cost to the gross figure (do not net incidental income) and tax that income separately under its proper head.

Common mistakes in ICDS III, IV and VII: Construction Contracts, Revenue and Government Grants

  • Excluding retention money from contract revenue

    Students follow the idea that retention is not yet receivable.

    Fix: Section 57(3)(a) says contract revenue includes retention money. Include it in full.

  • Reducing contract cost by interest or dividend earned on advances

    Accounting practice often nets incidental income against cost.

    Fix: Section 57(3)(b) bars this. Show such income separately under its own head.

  • Postponing revenue because collection is doubtful

    AS 9 allows deferral where ultimate collection is uncertain.

    Fix: ICDS IV does not allow postponement for uncertainty. Recognise the revenue and claim bad debt later.

  • Using the completion method for every service contract

    Students recall the 90-day rule and apply it too widely.

    Fix: Project completion applies only if the duration is not more than ninety days. Longer contracts use percentage of completion, or straight line for indeterminate acts.

  • Treating every government grant as taxable income in the year of receipt

    Students ignore the purpose of the grant.

    Fix: A grant for a depreciable asset reduces its cost or WDV. Check the purpose first.

  • Counting advances to suppliers as costs incurred when finding the stage of completion

    The amount is paid and shown in the books.

    Fix: Include only costs that reflect work performed to date.

Worked examples

Example 1

Sharma Infra Ltd. has a 3-year building contract for ₹20,00,000 (including ₹2,00,000 retention money). Estimated total cost is ₹16,00,000. Costs incurred: Year 1 ₹4,00,000; Year 2 cumulative ₹10,00,000. Compute revenue and profit for Year 2 under ICDS III.

Show the solution
  1. Contract revenue is ₹20,00,000. Retention money is already included, per section 57(3)(a).
  2. Year 1 stage of completion = 4,00,000 ÷ 16,00,000 = 25%. Revenue = ₹5,00,000.
  3. Year 2 cumulative stage = 10,00,000 ÷ 16,00,000 = 62.5%. Cumulative revenue = ₹12,50,000.
  4. Year 2 revenue = 12,50,000 − 5,00,000 = ₹7,50,000.
  5. Year 2 cost = 10,00,000 − 4,00,000 = ₹6,00,000.
  6. Year 2 profit = 7,50,000 − 6,00,000 = ₹1,50,000.

Answer: Year 2 revenue is ₹7,50,000 and profit is ₹1,50,000.

Example 2

Patel Engineers received a government grant of ₹6,00,000 towards a machine costing ₹20,00,000, with reasonable assurance of compliance. The machine was acquired in the year and put to use for 180 days or more, so depreciation is allowed at the full rate of 15%. The block has no opening WDV, and the machine is the only asset in it. Compute depreciation for the year and the treatment of the grant.

Show the solution
  1. The grant relates to a depreciable asset, so it is not taxed as income.
  2. It reduces the actual cost of the newly acquired machine: 20,00,000 − 6,00,000 = ₹14,00,000.
  3. With no opening WDV, the block's value for the year is this reduced cost of ₹14,00,000.
  4. The machine was used for 180 days or more, so the full rate applies: depreciation = 15% × 14,00,000 = ₹2,10,000.

Answer: The grant reduces cost to ₹14,00,000 and depreciation is ₹2,10,000.

Exam tips

  • Always state section 57 when writing on contract income. Quote the retention money and incidental income points, as they carry marks.
  • In MCQs, look for the 90-day and straight line triggers for service contracts.
  • For differences between ICDS IV and AS 9, lead with the uncertainty-of-collection point, then give one more difference.
  • Show cumulative and yearly workings in a small layout so the examiner can award step marks even if the final figure is wrong.
  • For grants, name the purpose first, then the treatment.

Practice questions from Income Computation and Disclosure Standards (ICDS)

ICDS III, IV and VII: Construction Contracts, Revenue and Government Grants: frequently asked questions

What is the difference between ICDS IV and AS 9?

The key difference is that ICDS IV does not allow revenue to be postponed because collection is uncertain. AS 9 allows postponement in that case. ICDS IV also applies the percentage of completion method to services, subject to the exceptions in section 57.

Is retention money part of contract revenue for tax?

Yes. Section 57(3)(a) of the Income-tax Act, 2025 says contract revenue includes retention money. You do not wait for its release before recognising it.

When is a government grant taxable under ICDS VII?

Only when there is reasonable assurance that you will meet its conditions and receive it. After that, the treatment depends on the purpose, such as reduction of asset cost, income over the period of obligations, or income when receivable.

When can I use the project completion method?

For a service contract lasting not more than ninety days. Longer service contracts use percentage of completion, and contracts with an indeterminate number of acts over a specified period use the straight line method.
