ESOP Taxation for NRIs: Exercise, Sale & DTAA Relief

Equity compensation is one of the most common tax surprises for NRIs, not because the rules are secret, but because they involve two separate taxable events, on two different amounts, sometimes in two different countries. Here is exactly how ESOP taxation works for NRIs, and where the double-taxation risk actually comes from.

The Two Taxable Events

Indian tax law treats ESOPs (and similar equity awards) as generating tax at two distinct points, not one:

1. At Exercise: Perquisite Tax

When you exercise your option and shares are actually allotted to you, the difference between the fair market value (FMV) of the shares on the exercise date and the exercise price you paid is treated as a perquisite, taxed as salary income under Section 17(2)(vi). This is taxed at your applicable slab rate for that year, exactly like a cash bonus would be, and the employer is generally required to withhold TDS on it under Section 192.

2. At Sale: Capital Gains Tax

When you eventually sell the shares, the FMV already taxed at exercise becomes your cost of acquisition. Capital gains tax applies only to the further appreciation between the exercise-date FMV and the actual sale price, not the full sale value. For unlisted shares (the norm for startup ESOPs before a listing event), long-term capital gains treatment requires a holding period of more than 24 months from the exercise date; shorter holdings are taxed as short-term gains.

The two events are not double taxation of the same value, they tax two different slices of the total gain, at exercise and at sale respectively. The confusion usually comes from not realising these are separate computations with separate cost bases.

Why NRIs Still Owe Indian Tax After Leaving

A common assumption is that becoming a non-resident removes Indian ESOP exposure. It doesn't, if the underlying employment services were rendered in India. Under the source rule in Section 9(1)(ii), salary is deemed to accrue or arise in India, and is taxable in India, if it relates to services rendered in India, regardless of the employee's residential status when the income is actually received or the option is exercised. An employee who worked in India for years, accumulated vested options, then relocated abroad and exercises those same options as an NRI, is still liable to Indian perquisite tax on the exercise, because the services that earned the option were performed in India.

This is a frequent trip-up for employees moving to the UAE, Singapore, or elsewhere after a Series B or pre-IPO vesting event, the move abroad changes future salary taxation, but it does not erase the Indian tax liability already attached to options earned during the India-resident years.

The Startup ESOP TDS Deferral

Section 192(1C) gives employees of DPIIT-recognised eligible startups a genuine cash-flow benefit: the employer can defer depositing the TDS on the ESOP perquisite for up to 48 months from the end of the relevant assessment year, or until the employee sells the shares, or until the employee ceases to be an employee of the company, whichever happens earliest.

Two things NRIs consistently misunderstand about this deferral:

• It defers deposit, not liability. The perquisite income is still taxed in the year of exercise for computing your total income and filing your return, the deferral only changes when the TDS amount is actually paid to the government.
• Leaving the company or India can trigger it early. If you resign, or the company treats a move abroad as a change in employment status, the 48-month clock can be cut short and the deferred TDS becomes due immediately, an unwelcome surprise if you assumed the full 4-year window applied regardless of your employment status.

See our related guide on DPIIT recognition and startup tax benefits for the eligibility criteria that determine whether a given startup's ESOP scheme even qualifies for this deferral.

Avoiding Double Taxation: What DTAA Actually Does

If you are tax resident in a country that also taxes equity compensation, the risk of paying tax twice on the same economic gain is real, but the fix is not automatic. The complication is that different countries tax equity awards at different trigger points: India taxes at exercise (perquisite) and sale (capital gains); some countries tax at vesting; others tax only at sale. These mismatched timings mean the "same" gain can fall into different tax years in different countries, which makes claiming a straightforward foreign tax credit harder than it sounds.

In practice, DTAA relief for ESOP double taxation generally works through:

• Foreign tax credit claimed in your country of residence for Indian tax paid on the perquisite or capital gains, subject to that country's own credit rules and documentation requirements (typically a certificate of Indian tax paid or withheld).
• Correct characterisation of the income (employment income vs capital gains) under the treaty, since the applicable article, and therefore the credit mechanism, differs between the two.
• Careful year-matching, aligning the Indian tax year in which perquisite or capital gains tax was paid against the foreign tax year in which the corresponding income is reported, which rarely lines up neatly given the timing mismatches above.

This is genuinely one of the more technical areas of NRI taxation, because it depends on the specific treaty, the specific country's equity compensation rules, and the specific timeline of your vesting, exercise, and sale. It is not something a standard tax-filing tool handles well.

TDS When an NRI Sells ESOP Shares

When an NRI sells shares, including unlisted ESOP shares in a private company, to a buyer, the buyer is generally required to deduct TDS under Section 195 (now Section 393(2) under the Income Tax Act 2025) on the capital gains element of the payment, the same regime that governs NRI property sale TDS. Because TDS is often computed conservatively on the full consideration rather than the actual gain, NRIs facing a large ESOP share sale (for example, in a company buyback or secondary sale ahead of an IPO) can apply for a Form 13 lower deduction certificate to bring the withholding closer to the actual tax owed, rather than waiting for a refund after filing an Indian return.

Practical Checklist for NRIs With ESOPs

1. Track exercise-date FMV carefully, this figure drives both your perquisite tax and your future capital gains cost base, and startups don't always provide it proactively once you've left the company.
2. Confirm whether TDS was actually deposited on exercise, especially if the startup used the Section 192(1C) deferral, and know what triggers early crystallisation.
3. Model the DTAA position before exercising, not after, since the exercise date itself is often a discretionary decision you control, and timing it against your residency status and the foreign country's tax year can materially change the outcome.
4. Plan for Section 195 TDS on any future share sale, and evaluate a Form 13 application if the sale is large relative to your actual computed gain.
5. Keep documentation, grant letters, exercise notices, FMV valuation reports, and TDS certificates, since reconstructing this years later across two countries is far harder than keeping it as you go.
