Section 72 — Mode of Computation of Capital Gains: The Complete Formula Explained

Section Analysis

Section 72 lays down the actual computation formula for capital gains, carried forward from Section 48 of the 1961 Act:

Capital Gain = Full Value of Consideration − (Cost of Acquisition + Cost of Improvement + Expenditure Wholly and Exclusively in Connection with the Transfer)

Key components:

  • Full value of consideration: Generally the actual sale price, but subject to deeming provisions (like Section 78's stamp-duty valuation, or Section 79's FMV rule for unquoted shares) that can override the stated price.
  • Cost of acquisition: What the taxpayer originally paid, subject to special rules for inherited/gifted assets (Section 73) and depreciable assets (Sections 74–75).
  • Cost of improvement: Capital expenditure incurred to improve the asset, excluding routine repairs.
  • Transfer expenses: Brokerage, legal fees, stamp duty paid by the seller, and other costs incurred wholly and exclusively for effecting the transfer.
  • For most long-term gains from FY 2025-26 onward, this computation is done without indexation benefit, at the flat 12.5% rate (see Part 1, Article 4), a significant shift from the earlier indexed-cost approach.

Case Laws

1. CIT v. Attili N. Rao [2001] 252 ITR 880 (SC) — The Supreme Court held that expenditure incurred by the seller to remove an encumbrance or defect in title, essential to effecting the sale, may qualify as expenditure "wholly and exclusively" in connection with the transfer and be deductible — illustrating the fact-sensitive scope of allowable transfer expenses.

2. Principle from K.P. Varghese v. ITO [1981] 131 ITR 597 (SC) — While decided in the context of a now-repealed provision presuming understatement of consideration, this ruling established the enduring principle that a statutory deeming fiction concerning sale consideration must be applied only where the specific statutory conditions triggering the fiction are actually satisfied — a principle of continuing relevance whenever a deeming provision (like Sections 78 or 79) interacts with the general Section 72 formula.

3. Cases on brokerage and legal fee deductions — Tribunals have consistently allowed brokerage commission, legal fees for drafting sale documents, and costs of obtaining necessary clearances as deductible transfer expenses, while disallowing unrelated or excessive/unsubstantiated claims — underscoring that these deductions require documentary proof of genuine, transaction-linked expenditure.

FAQs

Q1. Can I deduct routine repair costs as "cost of improvement"? Generally no — cost of improvement refers to capital expenditure that enhances the value or utility of the asset, not routine maintenance or repair expenses.

Q2. Is stamp duty paid on purchase included in cost of acquisition? Yes, typically — stamp duty and registration charges paid at the time of acquisition are generally includible in the cost of acquisition.

Q3. Can brokerage paid to a real estate agent be deducted? Yes, if genuinely incurred wholly and exclusively in connection with the transfer, and properly documented, brokerage is a well-established deductible transfer expense.

Q4. Does the formula change for long-term vs short-term gains? The basic formula structure is the same, but indexation of cost (historically available for long-term gains) has been removed for most asset classes under the current flat 12.5% LTCG regime effective from FY 2025-26.

Q5. What if my actual sale price is disputed by the tax department as too low? Deeming provisions like Section 78 (stamp duty valuation for land/building) or Section 79 (FMV for unquoted shares) may override your stated consideration figure — see Part 1, Article 8, and this article's next companion piece for details.

Precautions

  • Retain all invoices, contractor bills, and documentary evidence of capital improvements separately from routine maintenance receipts — only genuine improvement costs (properly substantiated) are deductible.
  • Keep brokerage agreements and payment receipts for any transaction — undocumented cash payments to brokers are a common area of dispute and disallowance.
  • Model your expected tax liability under the no-indexation flat-rate regime well before finalising a long-held asset's sale, since the removal of indexation can materially increase your effective tax versus historical expectations.
  • Don't assume your quoted sale price will automatically be accepted — check applicable deeming provisions (stamp duty valuation, FMV rules) before finalising transaction pricing, especially for property and unlisted securities.
