Capital Gain Computation Under Section 48 for NRIs
Section 48 Formula, Indexation & First Proviso Forex Conversion

Capital gain computation is where the actual Indian tax liability of every NRI sale gets calculated. Therefore, the formula, the components, and the special provisos under Section 48 of the Income Tax Act 1961 deserve careful attention. We deliver complete capital gain computation services at N D Savla & Associates — covering every Indian capital asset class for NRI clients across the world.

Our qualified Chartered Accountants have computed capital gains across every realistic asset and assessee profile. Furthermore, our team understands the First Proviso forex-conversion regime and the indexation mechanics. We also handle Section 49 cost substitution for inherited and gifted assets, Section 50C stamp duty value rule, and grandfathering FMV for pre-cut-off listed equity. Our capital gain computation work connects with the wider capital gain framework. Furthermore, we coordinate with capital gains on securities, capital gain on sale transactions, reinvestment exemptions, and filing return of income in India. As a result, the computed capital gain flows correctly into Schedule CG of ITR-2.

Section 48 of the Income Tax Act 1961 is the master computation provision for capital gains. Therefore, every capital gain — short-term or long-term, across every asset class — is computed using the Section 48 framework. The section also contains three provisos that adjust the computation for specific situations.

Section 48 provides a single formula. The taxable capital gain is the full value of consideration minus three deductions.

For long-term capital gains where indexation is permitted, the cost of acquisition and the cost of improvement are replaced by their indexed equivalents. Therefore, the long-term formula effectively works on inflation-adjusted costs. Furthermore, the section excludes Securities Transaction Tax from the deduction list — STT is not deductible against capital gain.

Full Value of Consideration

Full value of consideration is the total amount or value received (or accruing) to the seller on transfer. It covers cash received, the fair value of any non-cash consideration (such as another property received in exchange), and any liability of the seller assumed by the buyer (such as an existing housing loan taken over). Accrued consideration with staggered payment enters the full value at the time of transfer — not at the time of cash receipt. Under Section 50C, where the agreement price is less than the stamp duty value (the state government’s circle rate), the stamp duty value substitutes the agreement price, subject to a prescribed tolerance band. For shares or debentures transferred by gift or irrevocable trust under Section 47(iii), the market value on the date of transfer becomes the full value.

Cost of Acquisition

Cost of acquisition covers all expenses directly linked to acquiring the capital asset — the purchase price, stamp duty and registration charges on the purchase deed, brokerage, legal fees, and other direct acquisition costs. Section 49 substitutes the previous owner’s cost and holding period for inherited and gifted assets, typically converting inherited Indian property into a long-term asset in the heir’s hands. For assets acquired before the cost-inflation base date, the Fair Market Value on that date can be substituted where it exceeds actual cost. For listed equity acquired before the Section 112A grandfathering cut-off, the grandfathered FMV is the higher of actual cost or cut-off-date FMV.

Cost of Improvement

Cost of improvement covers all capital expenditure on enhancements to the asset after acquisition — extensions, additional floors, structural renovations, additions of bathrooms or kitchens, perimeter walls, and garages. Routine repairs and maintenance do not qualify. The cost also covers capital expenditure that the previous owner incurred on inherited or gifted assets. Capital expenditure incurred before the cost-inflation base date is ignored — only post-base-date improvements are eligible.

Transfer Expenses

Transfer expenses cover all costs incurred wholly and exclusively in connection with the transfer — brokerage at the time of sale, legal fees on the sale deed, stamp duty borne by the seller, advertising costs to find a buyer, registration fees borne by the seller, and travel costs specifically incurred for the transfer. Securities Transaction Tax is not a transfer expense and does not reduce the capital gain. Post-transfer expenses, such as legal disputes after the sale, are also not deductible.

Indexation under the Second Proviso to Section 48 is the inflation-adjustment mechanism for long-term capital gains. Therefore, indexation reduces the taxable capital gain by allowing the cost of acquisition and the cost of improvement to grow at the official Cost Inflation Index rate.

The same formula applies to the cost of improvement, using the CII of the year of improvement as the denominator — so every improvement gets indexed from its own date. The Cost Inflation Index is published by the Central Board of Direct Taxes (CBDT) each year through a notification.

Indexation is available only on long-term capital gains and only for assets falling under Section 112 (other than those carved out). Listed equity under Section 112A, Specified Mutual Funds under Section 50AA, and certain other categories do not get indexation. Furthermore, under the current framework, indexation has been largely removed for transfers on or after the prescribed amendment date. A transitional choice between the indexed rate and the flat unindexed rate is available for resident individuals and HUFs on pre-amendment immovable property.

The First Proviso to Section 48 is the most NRI-specific provision in the entire capital gain framework. Therefore, every NRI selling shares or debentures of an Indian company must consider whether the First Proviso applies. The regime can substantially reduce the rupee capital gain by neutralising the impact of rupee depreciation.

Under the First Proviso, three figures — the full value of consideration, the cost of acquisition, and the transfer expenses — get converted into the same foreign currency originally used to purchase the shares or debentures. The capital gain is computed in that foreign currency, then re-converted into Indian Rupees at the prevailing Telegraphic Transfer Buying Rate (TTBR) on the date of transfer.

The First Proviso neutralises rupee depreciation during the holding period — so if an NRI bought Indian company shares years ago when the rupee was stronger, that depreciation is not treated as taxable gain. The regime also carries forward across successive reinvestments into further Indian-company shares or debentures, stopping only when the NRI exits the asset class entirely. Indexation under the Second Proviso is not available alongside the First Proviso, so the NRI must choose between the two — and our team models both computations before recommending the route.

Capital losses can be set off against capital gains under Sections 70 and 74 of the Income Tax Act 1961. Therefore, the loss positions of an NRI’s prior years and same-year other transactions enter the overall capital gain computation. Set-off rules differ between short-term and long-term capital losses.

Within the same financial year, short-term capital loss can be set off against both short-term and long-term capital gain — it is fungible across the entire category. Long-term capital loss, however, can only be set off against long-term capital gain, not against short-term capital gain. Unutilised capital loss can be carried forward for the prescribed number of subsequent assessment years for set-off against future gains of the same character. Crucially, the carry-forward right is preserved only if the income tax return for the loss year is filed within the original due date — late filing forfeits the carry-forward entirely. Hence, on-time ITR-2 filing matters even in years where there is only a loss to report.
