Section 72 NRI Share Capital Gains: Foreign Currency Computation in 2026

Direct answer: Section 72 of the Income-tax Act, 2025 preserves a special computation mechanism for a non-resident who sells shares in, or debentures of, an Indian company that were acquired using foreign currency. Instead of measuring the gain only in rupees, the law converts the acquisition cost, transfer expenses and sale consideration into the same foreign currency used for the original investment, computes the gain in that currency, and then reconverts the resulting gain into rupees. The purpose is to reduce distortion caused purely by exchange-rate movements.

This rule is important for NRIs and other non-residents holding Indian company shares because a rupee-only calculation can sometimes show a large apparent gain even when the investor has made a much smaller gain in the currency actually invested. Section 72 does not create a tax exemption or a special tax rate; it changes the computation mechanism. The applicable tax rate, holding-period rule, treaty position and withholding consequences must still be tested separately.

Why this matters for NRIs and overseas investors

The Income Tax Department has expressly confirmed that the Income-tax Act, 2025 retains the mechanism that was earlier contained in the first proviso to section 48 of the Income-tax Act, 1961. The Department states that section 72 continues to allow a non-resident to compute gains on shares or debentures of an Indian company in the original foreign currency and then reconvert the net gain into rupees. This is intended to neutralise the effect of exchange-rate fluctuations on the capital-gains computation.

When can Section 72 apply?

As a practical starting point, Section 72 is relevant where all of the following features are present:

• The taxpayer is non-resident for Indian income-tax purposes for the relevant tax year.

• The capital asset transferred is shares in, or debentures of, an Indian company.

• The investment was originally made using foreign currency.

• The transfer results in a capital-gains computation under Indian tax law.

The rule is transaction-specific. It should not be assumed to apply merely because the seller is an NRI, nor should it be extended automatically to every Indian security, mutual-fund unit, property or other asset. The statutory wording and the actual acquisition trail should be checked.

How Rule 52 converts the transaction into foreign currency

Rule 52 of the Income-tax Rules, 2026 prescribes the exchange-rate mechanics for Section 72. It uses the foreign currency initially utilised to purchase the shares or debentures and applies different exchange rates to different parts of the computation.

1. Cost of acquisition: convert the rupee cost using the average of the telegraphic transfer buying rate and telegraphic transfer selling rate of the relevant foreign currency on the acquisition date.

2. Transfer expenses: convert qualifying transfer expenditure using the average of the telegraphic transfer buying and selling rates on the transfer date.

3. Sale consideration: convert the full value of consideration using the average of the telegraphic transfer buying and selling rates on the transfer date.

4. Resulting foreign-currency capital gain: reconvert the gain into rupees using the telegraphic transfer buying rate on the transfer date.

Rule 52 therefore does not simply translate a rupee gain into dollars, pounds or another currency at one closing rate. The computation works asset-by-asset using prescribed exchange rates for acquisition, transfer expenses, consideration and final reconversion.

Worked example: why the foreign-currency method can change the result

Assume an NRI originally invests USD 100,000 in shares of an Indian company. At acquisition, the corresponding rupee cost is ₹70 lakh. Years later, the shares are sold for ₹95 lakh when the rupee has weakened materially against the US dollar. A simple rupee comparison suggests a gain of ₹25 lakh before expenses.

Under Section 72, the acquisition cost and sale consideration are first translated using the prescribed Rule 52 rates in the original investment currency. If the foreign-currency value of the ₹95 lakh sale proceeds is, for example, only USD 112,000, the economic gain measured in the original currency is closer to USD 12,000 before expenses, not the rupee movement of ₹25 lakh. The final taxable capital gain is then reconverted into rupees using the prescribed buying rate on the transfer date.

This example is illustrative only. Actual calculations must use the exchange rates specified in Rule 52 and the taxpayer’s documentary evidence for the original foreign-currency investment.

Section 72 is a computation rule, not a tax-rate concession

One of the most important practical distinctions is that Section 72 affects how the gain is computed, not whether the gain is exempt or which rate ultimately applies. After computing the capital gain, the taxpayer must still determine whether the asset is short-term or long-term, whether a special-rate provision applies, whether securities-transaction-tax conditions matter, whether Section 214 or another special NRI provision applies, and whether an applicable DTAA changes India’s taxing rights or rate.

For this reason, a Section 72 computation should sit inside a broader NRI exit-tax review rather than be treated as a standalone relief claim.

How Section 72 differs from Section 215 reinvestment relief

PGT & Associates recently covered Section 215, the special NRI reinvestment exemption for qualifying foreign-exchange assets. The two rules solve different problems. Section 72 changes the measurement of capital gains on qualifying Indian-company shares or debentures. Section 215, by contrast, can exempt qualifying long-term capital gains fully or proportionately where the statutory reinvestment conditions are satisfied.

An NRI disposing of qualifying shares may therefore need to test the computation rule first and then separately examine whether a reinvestment exemption is available. See our detailed Section 215 guide: https://www.pgtandassociates.com/post/nri-section-215-reinvestment

Documents an NRI should retain

• Original bank advice, inward-remittance proof or NRE/NRO/FCNR trail showing the foreign currency used for acquisition.

• Broker contract notes, subscription documents or share-purchase agreements showing acquisition date, quantity and rupee cost.

• Evidence of the currency originally utilised for the investment.

• Sale contract notes, share-purchase agreement or other transfer documentation.

• Proof of transfer expenses such as brokerage and transaction charges where deductible.

• Exchange-rate workings under Rule 52, including the relevant telegraphic transfer buying and selling rates.

• Tax residency certificate and Form 10F / current equivalent documentation where treaty relief is being evaluated.

• TDS certificates, lower-deduction certificate records and Indian return-filing support.

Common mistakes in Section 72 computations

• Computing the gain only in rupees and ignoring the statutory foreign-currency mechanism.

• Using a generic RBI or internet spot rate instead of the exchange rates prescribed by Rule 52.

• Using a different currency from the currency originally utilised to purchase the shares or debentures.

• Assuming Section 72 automatically reduces the tax rate or creates an exemption.

• Applying the mechanism to assets that are not shares or debentures of an Indian company without checking the statute.

• Ignoring treaty analysis, withholding tax and return-filing consequences after the gain is computed.

• Failing to preserve the remittance trail needed to prove the original foreign-currency investment.

Practical checklist before an NRI sells Indian company shares

1. Confirm Indian tax residency for the year of transfer.

2. Identify the exact asset and whether it falls within Section 72.

3. Trace the original foreign-currency acquisition and supporting bank records.

4. Compute the gain under Rule 52 using the prescribed rates.

5. Classify the gain as short-term or long-term under the applicable holding-period rules.

6. Test any special NRI taxation or reinvestment provision, including Section 215 where relevant.

7. Review the applicable DTAA and beneficial-ownership / residency documentation.

8. Review Indian TDS and lower-deduction-certificate options before closing the transaction.

9. Plan repatriation and FEMA documentation separately from the income-tax computation.

10. Reconcile the final computation with the Indian income-tax return and TDS credit.

FAQs

1. Does Section 72 apply only to NRIs?

Section 72 is framed for a non-resident assessee. An NRI can qualify, but the relevant question is non-resident status under Indian income-tax law for the tax year, not merely citizenship or OCI/NRI terminology used for banking or FEMA purposes.

2. Does Section 72 apply to sale of Indian property?

No. The specific mechanism discussed here concerns shares in, or debentures of, an Indian company. Property capital gains are governed by different computation provisions.

3. Can I simply use the exchange rate on the sale date for the entire calculation?

No. Rule 52 prescribes separate exchange-rate rules for the acquisition cost, transfer expenses, sale consideration and final reconversion of the capital gain.

4. Does this mean exchange-rate gain is completely ignored?

The mechanism is designed to reduce distortion from currency movements by measuring the transaction in the original investment currency. The precise taxable result depends on the prescribed Rule 52 rates and the transaction facts.

5. Can Section 72 and DTAA relief both matter?

Yes, but they address different questions. Section 72 determines the domestic-law computation of the gain. The DTAA may affect India’s taxing right or applicable rate. Treaty analysis comes after accurately identifying the domestic-law income.
