The reliefs are real, but they hang on being resident and on the old regime
Start with what changes in your favour. The moment your return makes you a resident, doors that were shut to you as an NRI open. As a senior citizen, 60 to 79, your basic exemption rises to ₹3,00,000, and at 80 and above to ₹5,00,000, against the ₹2,50,000 an ordinary taxpayer gets. You can also claim the ₹50,000 deduction on deposit interest under 80TTB, which as an NRI you were barred from and had to take the smaller ₹10,000 80TTA instead. The mirror image is what an NRI cannot claim while still non-resident.
The catch is that every one of these lives on the old tax regime. The new regime gives the same ₹4,00,000 exemption to everyone regardless of age and switches off 80TTB, 80D and the rest of the chapter. And the new regime is the default: file without a choice and you file on it, senior reliefs gone. So the reliefs being available is only half the story; whether you actually get them depends on the regime you file under.
The new regime is the default, and it erases the senior uplift
Here is the trap in one line: the reliefs are opt-in, and the regime that carries them is opt-out. Since 2023-24 the new regime under Section 115BAC is what your return uses unless you positively choose the old one. On the new regime the ₹5,00,000 super-senior exemption collapses to the flat ₹4,00,000 everyone gets, 80TTB disappears, and 80D and 80DDB go with it.
What the new regime gives back is a lower rate ladder and, for 2025-26, a rebate under Section 87A that wipes out the tax entirely on total income up to ₹12,00,000. That is the number that changes the whole calculation. It means a senior whose Indian income is a pension and some deposit interest adding up to under ₹12 lakh may pay nothing at all on the new regime, even without a single senior deduction, while the old regime with its ₹3,00,000 exemption would have taxed the same income. The default is not automatically the villain; filing on autopilot without checking is.
Who actually wins on each regime
The choice turns on how much income you have and how much you can deduct. Two clear patterns:
| Your situation | Usually better |
|---|---|
| Indian income up to about ₹12 lakh, few deductions | New regime, the rebate makes it nil |
| Higher income, or large 80C, 80D, 80TTB, 80DDB or home-loan claims | Old regime, the deductions and senior exemption bite |
A returned senior living mainly on deposit interest and a modest pension usually sits in the first row, and the new regime's nil band beats the senior exemption. A senior with a large rental income, a home loan, heavy medical costs under 80DDB and a full 80TTB has enough to deduct that the old regime pulls ahead. Neither is a rule you can apply blind; the only reliable answer is to compute the tax both ways on your actual numbers.
The RNOR years change the answer, so revisit it each year
Your regime choice is not a one-time decision, because your income itself changes as you settle in. For the first two or three years back you are usually Resident but Not Ordinarily Resident, and while that lasts your foreign pension and foreign interest stay outside the Indian net, so your taxable Indian income is lower, more likely under the ₹12 lakh nil band, and the new regime often wins.
The year you become ordinarily resident, your worldwide income, the foreign pension included, becomes taxable in India, your total jumps, and the old regime's deductions may suddenly be worth more than the rebate. So the sensible pattern is to redo the old-versus-new comparison every year through the transition, not lock in once. A taxpayer without business or professional income can switch freely between the regimes year to year simply by choosing in the return; only someone with business or professional income is tied down by the one-time Form 10-IEA rule.
A worked example: Lakshmi, 67, back in Chennai
Lakshmi returned to Chennai after nineteen years in the Gulf and is now a resident, in her first ordinarily-resident year. Her Indian income for the year is ₹8,00,000 of interest on her NRO and resident deposits and a ₹2,50,000 foreign pension that is now taxable, ₹10,50,000 in all. She assumes that as a senior she should file on the old regime for the ₹3,00,000 exemption and her ₹50,000 80TTB.
Run both ways, the old regime taxes her at roughly ₹1,00,000: after the ₹3,00,000 exemption, 80TTB and an 80D health premium, her slab tax lands near a lakh because income above ₹5,00,000 is taxed at 20 per cent and she gets no 87A rebate at this level. On the new regime her tax before rebate is about ₹45,000, and because her total is under ₹12,00,000 the Section 87A rebate wipes it out to nil. Choosing the new regime, the one she was about to opt out of, saves her the whole ₹1,00,000. Her CA runs exactly this comparison, and it would flip to the old regime only the year her income climbs well past the nil band.
