A resident with the same gain can pay zero. As an NRI you pay from the first rupee. Here is why.

Picture two people who sell the same mutual fund on the same day and make the same 3 lakh long-term gain. One is a resident with a small pension and little other income. The other is an NRI. The resident can walk away paying almost nothing. The NRI pays the full rate. Same asset, same gain, very different bill.

The reason is a single word buried in the tax law. Every individual has a basic exemption limit, the slice of income below which you pay no tax. Residents are allowed to set their capital gains against any unused part of that limit. NRIs are not. The rule that permits the set-off says, in plain terms, that it is for a resident individual. So a low-income resident can shelter a gain under the exemption and pay little or nothing, while an NRI is taxed on the gain from the very first rupee.

This is not a loophole a resident is exploiting. It is written into Sections 111A, 112 and 112A, which set the special rates for capital gains: the adjustment against the basic exemption limit is expressly limited to residents. Knowing it exists is the difference between planning around it and being blindsided by a tax bill you did not expect.

Here is the mechanic. Say the basic exemption limit is 4 lakh under the current regime. A resident whose only income is a 3 lakh long-term capital gain has used none of that 4 lakh limit on other income. The proviso to the capital-gains sections lets that resident pull the gain down into the unused exemption, so the whole 3 lakh sits inside the limit and the tax is nil.

Now make that same person an NRI. The proviso does not apply. The 4 lakh basic exemption still shelters ordinary income like Indian rent or interest up to the limit, but it cannot be stretched over the capital gain. The gain is taxed at its own special rate straight away, with no first slice knocked off for the exemption.

So the basic exemption is not gone for an NRI. It still works against ordinary income. What an NRI loses is the ability to park capital gains inside it. For someone whose Indian income is mostly capital gains, that is the whole ball game.

There is good news, and it gets muddled online, so be clear about it. NRIs do keep the annual exemption built into Section 112A. Long-term gains on listed shares and equity mutual funds are tax-free up to 1.25 lakh in a financial year, and only the amount above that is taxed at 12.5 percent. That 1.25 lakh is available to residents and NRIs alike. It sits inside Section 112A itself, so it is not caught by the resident-only restriction on the basic-exemption set-off.

You will see some pages say NRIs are taxed under Section 115AD instead of 112A. For an individual NRI, that is not right. Section 115AD is the regime for foreign institutional investors and specified funds, not for an ordinary NRI holding units in their own name. An individual NRI's listed-equity long-term gains fall under Section 112A, at 12.5 percent above the 1.25 lakh, exactly like a resident, just without the extra basic-exemption cushion.

So the picture for listed equity is simple: you get the 1.25 lakh yearly exemption, you do not get the basic-exemption set-off on top of it.

The bite depends on what you sold, because the special rate is different by asset, and only listed equity carries the 1.25 lakh cushion.

Listed shares and equity mutual funds, held long term: 12.5 percent, but only on the gain above 1.25 lakh in the year. Short term, held a year or less: 20 percent under Section 111A, from the first rupee, with no 1.25 lakh break.

Everything else, property, land, unlisted shares, gold, debt funds: taxed at its own rate, generally 12.5 percent long term without indexation for an NRI, or at slab or 20 percent depending on the asset and holding period, again from the first rupee. None of these has a 1.25 lakh cushion, and none of them lets an NRI use the basic exemption.

On top of the rate, the tax is usually taken at source. When an NRI sells, the buyer or the fund deducts tax under Section 195 before the money reaches you, at these special rates. So the shortfall is not just theoretical, it is withheld up front, and if too much was taken, you only get it back by filing a return.

There is a second resident-only benefit worth naming, because NRIs keep hearing about it and assuming it applies to them. Under the current regime, a resident with total income up to 12 lakh pays no tax, thanks to the Section 87A rebate. It is a headline number, and it is genuinely large.

It does two things an NRI cannot rely on. First, the rebate is for residents only, so an NRI does not get it at all. Second, even for a resident, the rebate does not wipe out tax on these special-rate capital gains, it applies to normally taxed income, not to gains charged under Sections 111A, 112 and 112A. So the twelve-lakh-tax-free line you may have read about is doubly not your situation as an NRI selling shares or property.

The takeaway is not to bank on any of the low-income shelters. As an NRI, your capital gain is taxed on its own terms, at its own rate, from the start.

You cannot buy back the basic-exemption cushion, but there are real, legal ways to bring the bill down, and they are where the planning happens.

Use the 1.25 lakh, every year. It resets each financial year. If you are sitting on a large equity gain and are not forced to sell in one go, booking it across two or more years lets you take the 1.25 lakh exemption more than once.

Check your treaty. Some of India's treaties, notably with the UAE and Singapore, can assign the gain on certain securities to your country of residence, which may tax it lightly or not at all. That is a bigger lever than the basic exemption ever was, and it is worth confirming for your exact holding and country.

Reinvest, where the gain is from property or land. The reinvestment reliefs under Sections 54, 54F and 54EC are available to NRIs, so rolling a property gain into another house or into specified bonds can defer or remove the tax the ordinary way.

Recover over-deducted tax. Because Section 195 tax is withheld up front at the special rate, NRIs are often over-deducted. Filing a return, with a lower-deduction certificate where it is worth it, is how you claim the excess back.
