A tribunal has confirmed a tax office cannot use your ESOP exercise price as cost basis once the appreciation was already taxed as salary. It’s real relief — but it’s one bench’s ruling, not a rewritten law.
Plenty of NRIs left Indian employers holding stock options — exercised while still in India, or exercised later on an Indian company’s cap table after moving abroad. Years on, when those shares finally get sold, the capital gains computation hinges on a single number: what counts as the cost of acquisition. Get it wrong, and a tax office can end up taxing the same rupee of gain twice — once as salary when the option was exercised, once as capital gains when the shares were sold.
That’s exactly the dispute a Mumbai bench of the Income Tax Appellate Tribunal settled on 31 July 2026, in a case involving an NRI who had worked for the UK branch of an Indian IT company. He had exercised ESOPs, paid tax on the exercise-date appreciation as a perquisite — in his case, in the UK rather than India — and then computed his eventual capital gains using the fair market value on the exercise date as his cost basis. The assessing officer disagreed, argued the perquisite hadn’t been taxed in India, and used the original exercise price instead — adding back roughly ₹29.6 lakh as short-term capital gains on the difference.
ESOPs are taxed in two distinct events, and the whole dispute sits in the join between them. Exercise your option, and the gap between the share’s fair market value that day and what you paid for it is taxed immediately as salary income under Section 17(2)(vi) — regardless of whether you go on to sell the shares that year, next year, or a decade later. Sell the shares eventually, and ordinary capital gains rules apply: sale price minus cost of acquisition.
Section 49(2AA) is the provision that stops those two events from taxing the same money twice. It fixes the cost of acquisition for the later sale at the same FMV figure that was already brought to tax as a perquisite. Use the lower exercise price instead, and the entire FMV-minus-exercise-price spread — already taxed once as salary — gets swept back into the capital gains number and taxed a second time.
The assessing officer’s argument in this case was a technicality: since the perquisite had been taxed abroad rather than in India, Section 49(2AA) — an Indian tax provision — shouldn’t apply to import that FMV figure. The tribunal rejected it outright, holding that the section’s applicability doesn’t turn on which country taxed the perquisite, and reinforced the point by invoking the non-discrimination clause in the India-UK tax treaty — an NRI can’t be denied the cost-basis treatment a resident taxpayer would get simply for having relocated.
It’s worth being precise about what an ITAT ruling actually is. It’s a tribunal decision binding on the parties in that specific case — genuinely useful as persuasive precedent if your CA is arguing the same point against a tax officer, but not a rewrite of the statute, and not something every assessing officer is obligated to follow. Tax departments routinely appeal favourable rulings to the High Court, and there’s no indication yet either way on this one.
It also isn’t a blanket rule for every ESOP scenario. A separate ITAT Hyderabad ruling went the other way for a taxpayer holding ESOPs in a foreign parent company, because a different provision — Section 49(2AB), tied to whether the employer paid Fringe Benefit Tax — governed those facts instead of Section 49(2AA). Which section applies depends on whose shares they are and how the perquisite was originally taxed, so this ruling supports NRIs with Indian-company ESOPs specifically, not ESOP taxation in general.
If you exercised ESOPs of an Indian company, already paid tax on the exercise-date spread, and are sitting on shares you plan to sell — or have already filed a return using the exercise price as cost basis — this is worth a direct conversation with a CA rather than something to file away as settled law.
