NRE vs NRO After-Tax Calculator

The two accounts are not two flavours of the same thing

An NRE and an NRO account look almost identical on a bank's website — both rupee accounts, both held by non-residents, often at rates within a quarter of a percent of each other. They do fundamentally different jobs. An NRE account exists to hold money you have earned abroad and brought into India. Interest on it is exempt from Indian income tax for a person who is a non-resident under exchange-control law, no tax is deducted at source, and both principal and interest can be sent back out of India freely — no ceiling, no certificate, no chartered accountant. An NRO account exists to hold money that arises in India: rent, dividends, pension, sale proceeds, an inheritance. Interest on it is fully taxable at your slab rate, tax is deducted at source under Section 393, and remittance abroad is capped and papered.

This is why the choice is usually not a choice at all. Money earned abroad and remitted in belongs in an NRE account, and there is no reason to put it anywhere else. Money arising in India cannot be put into an NRE account and must sit in an NRO one. The genuine decision points are narrower: where you have a maturing NRO balance and are deciding whether to repatriate and re-remit into NRE, where a bank is quoting a materially better NRO rate and you want to know whether it is worth it, and where you are approaching a return to India and need to know what changes.

The calculator answers all three by reducing both accounts to a single comparable figure — the after-tax yield on the same money. On a ₹50 lakh deposit at 7% NRE against 7.25% NRO, an NRI with ₹20 lakh of other Indian income nets 7% from the NRE deposit against 5.37% from the NRO one, a difference of ₹81,750 a year and ₹4,08,750 over a five-year term. The quarter-point rate advantage on NRO is not close to enough to cover a 26% marginal tax bite. The rate a bank would have to offer on NRO to genuinely match that NRE deposit is around 9.5%, which no bank is offering.

Why the NRO withholding is so much heavier than a resident faces

A resident with a fixed deposit has tax deducted at 10%, and only above a threshold that most small depositors never cross. A non-resident with an NRO deposit has tax deducted under Section 393 at the rate in force for a non-resident — 30% plus 4% cess, giving 31.2% — from the first rupee of interest, with no threshold at all. That is more than three times the resident rate, and it applies regardless of whether you have any liability. A non-resident whose only Indian income is ₹3,62,500 of NRO interest has a tax liability of nil, since the interest sits below the basic exemption, and still has ₹1,13,100 withheld.

Two familiar remedies are closed off. Form 15G and Form 15H, the declarations residents file to stop deduction where their income is below the taxable limit, are available to residents only — a non-resident cannot file them, and a bank that accepts one has made an error you will both regret. And the Section 156 rebate that makes income up to ₹12 lakh tax-free applies to resident individuals only, so an NRI cannot rely on it to argue that no tax is due. What remains open are two real routes: a lower-deduction certificate under Section 395, obtained in advance and directing the bank to deduct at a reduced rate or none; and a treaty rate under Section 159 where your country of residence has a treaty with India.

The practical significance is cash flow rather than final tax. Over-withheld tax is not lost — it is recovered by filing an Indian return and waiting for the refund, typically twelve months or more after the interest was credited, with no meaningful compensation for the delay. But for someone living abroad who has no other reason to file in India, that recovery involves an Indian return, a validated Indian bank account for the refund, and a reconciliation against Form 26AS. A significant number of NRIs simply never claim it, which converts a timing problem into a permanent loss.

Treaty relief under Section 159 — real, but conditional

Where your country of residence has a tax treaty with India, the interest article of that treaty usually caps the rate at which India may tax interest arising in India — commonly 10%, 12.5% or 15% depending on the country. Relief is given effect through Section 159 of the Income-tax Act, 2025, and where the treaty rate is lower than the domestic rate, the treaty rate prevails. On ₹3,62,500 of NRO interest, moving from the domestic 31.2% to a 15% treaty rate reduces the withholding from ₹1,13,100 to ₹54,375 — nearly ₹59,000 a year that stays in your account instead of waiting for a refund. Where no treaty exists, Section 160 provides unilateral relief for foreign tax paid on the same income.

The relief is not automatic, and this is where it goes wrong in practice. Your bank will apply the domestic rate unless you affirmatively establish entitlement, which means giving it a valid Tax Residency Certificate issued by the tax authority of your country of residence, Form 10F filed electronically on the Indian income-tax portal, a PAN, and a declaration that you have no permanent establishment in India. All of these are annual — a TRC covers a period and lapses, and a Form 10F filed for one year does not carry into the next. Every year a depositor forgets, the bank reverts to 31.2% and the difference goes back to being a refund claim.

One thing a treaty rate does not do is reduce your tax. It caps the withholding. If your slab liability on the interest is higher than the treaty rate collected — which happens as soon as your other Indian income pushes the interest into the 20%, 25% or 30% band — the balance remains payable, and paying it at filing rather than through advance tax instalments attracts interest under Sections 424 and 425. The calculator shows this explicitly: select a 15% treaty rate with ₹20 lakh of other income and it reports a shortfall still payable rather than a refund. Treaty relief is a cash-flow improvement and, at low income levels, a genuine reduction; at higher income levels it is only the former.

Repatriation — the difference that never shows up in a rate comparison

Even where the after-tax arithmetic is close, the two accounts are not equivalent, because getting the money out of India is a completely different exercise. NRE balances are fully and freely repatriable. Principal and interest can be remitted abroad at any time, in any amount, with no annual ceiling, no certificate and no professional involvement — you instruct the bank and the money moves. This is the quiet reason NRE accounts are preferred by people who may need their money at short notice or who are managing currency exposure actively.

NRO balances are subject to a ceiling of USD 1 million per financial year across all your NRO accounts and assets, and each remittance requires Form 15CA filed by you on the income-tax portal together with Form 15CB, a certificate from a chartered accountant confirming that the applicable Indian tax has been paid or provided for. That is a real cost in fees and, more significantly, in time — a remittance you expected to take a day can take a week or more if the certificate has to be arranged from abroad. For someone repatriating sale proceeds or an inheritance, the USD 1 million ceiling can also bind outright, forcing the remittance across two financial years.

A rate comparison that ignores this is incomplete. A quarter-point advantage on an NRO deposit is worth ₹12,500 a year on ₹50 lakh; the cost of a capped, certified, delayed exit route is harder to price but is frequently worth more than that to the person who needs the money. Where the after-tax figures come out level, the sensible tie-break is NRE, every time. Where NRO comes out ahead — which the calculator will show honestly, and which happens when your total Indian income is low enough to keep the interest in a light slab — the margin should be weighed against the repatriation friction rather than banked automatically.

The year you come home — what happens to the NRE exemption

The exemption on NRE interest belongs to a person, not to an account. It is available to someone who is a non-resident under exchange-control law, and it ends when that description stops fitting. When you return to India for good, your NRE accounts must be redesignated as resident rupee accounts, or the funds moved to a Resident Foreign Currency account, and the interest becomes ordinary taxable income from that point. Nothing about the deposit changes — same bank, same certificate, same rate — but the tax treatment reverses entirely.

The scale of that reversal is worth seeing before it happens rather than after. Toggle the calculator to resident status on a ₹50 lakh NRE deposit at 7% with ₹20 lakh of other Indian income and ₹3,50,000 of previously exempt interest becomes taxable, costing ₹91,000 a year. Across a portfolio of NRE deposits built up over a working life abroad, the change in annual after-tax income on the year of return commonly runs into several lakhs, and it lands in a year that is already financially busy. It is also frequently overlooked in the retirement arithmetic of people planning their return, because the NRE exemption has been a constant for so long that it stops being treated as conditional.

Two points of nuance. First, becoming Resident but Not Ordinarily Resident — the transitional status many returning NRIs hold for two or three years — is genuinely valuable for foreign income, which broadly stays outside the Indian net during that window. But it does not by itself preserve the NRE interest exemption, which turns on your status under exchange-control law rather than on the RNOR classification. Second, an RFC account is the instrument designed for this transition and is worth understanding before the move rather than after, particularly where you want to keep balances in foreign currency. Both are decisions best taken in the months before you return, when the options are still open, rather than in the filing season afterwards when they are not.

How to read the result — and what the model leaves out

The number to focus on is the after-tax yield pair, not the rupee difference, because the yield is what lets you compare against anything else you might do with the money. An NRE deposit at 7% yields 7% after tax while you are non-resident, which is a genuinely unusual thing in a taxable world and is why NRE deposits hold their place in NRI portfolios despite unexciting headline rates. An NRO deposit at 7.25% yields 5.37% to someone in the 25% bracket and less than 5% to someone at the top of the table. The marginal tax shown is deliberately the additional tax the interest creates on top of your other income, rather than an average rate, because that is the true cost of the deposit at the margin and it is what should drive the decision.

The model makes some simplifications you should know about. Interest is treated as paid out annually rather than compounded, which suits a non-cumulative deposit exactly and slightly understates a cumulative one over a long tenure — though it understates both sides similarly, so the comparison holds. It assumes the same rate applies throughout the tenure, whereas a five-year deposit renewed in stages will not. It applies surcharge at the headline thresholds without modelling marginal relief where income sits just above one of them. It does not model currency risk, which for someone whose spending is in dollars, pounds or dirhams is often a larger factor than the tax difference — a rupee deposit yielding 7% net is not obviously better than a foreign-currency alternative once depreciation is priced in, and an FCNR deposit sidesteps that question entirely while also carrying an exemption.

It also stops at the deposit itself. It does not consider whether the money should be in a deposit at all, whether an FCNR account better matches your liabilities, or how any of this interacts with your tax position in your country of residence — where NRE interest, exempt in India, may well be fully taxable, since a domestic Indian exemption does not bind a foreign tax authority. That last point catches people from countries that tax worldwide income on their residents, and it deserves its own conversation. For the question the calculator exists to answer — on the same money, which account leaves me with more, and what does my status change cost me — the figures it produces are the ones to take into that conversation.
