When NRE and FCNR Interest Stops Being Tax-Free for a Returning NRI: The Two Different Switches Most People Get Wrong

You return to Bengaluru in June after eleven years in the US, and your two foreign-currency holdings look almost identical on the bank statement: an NRE fixed deposit of Rs 30,00,000 earning 7%, and an FCNR(B) deposit of USD 60,000 earning 4.5%. Both were tax-free while you were abroad. Both feel like they should carry on being tax-free for a while now that you are home and still, on the income-tax day count, Not Ordinarily Resident. They do not. One of them stops being tax-free on the day you land, and the other can keep running tax-free for another two to three years until it matures. Same bank, same currency story, two completely different answers, and the reason is buried in the exact wording of two different clauses of Section 10.

The 30-second answer: NRE interest is exempt only under Section 10(4)(ii), and only for a "person resident outside India" under FEMA. The day you return to India with intent to stay, your FEMA status becomes resident, the exemption ends, and NRE interest is taxable from that date, even while you are still RNOR for income tax. The account must be redesignated to a resident rupee account or moved to an RFC account, and you must tell the bank, usually within 30 days. FCNR(B) interest is different: Section 10(15)(iv)(fa) exempts it for a person who is non-resident OR not ordinarily resident, so an existing FCNR deposit can run tax-free through your RNOR window until maturity, then roll into RFC. Both exemptions end when you become Resident and Ordinarily Resident (ROR), usually after two to three financial years.

This is one of the most expensive misunderstandings a returning NRI carries home, because it feels intuitive that "both were tax-free, both stay tax-free for a bit" and the intuition is half wrong. If you want the full master picture of building your first Indian return after coming back, the residency mechanics that decide everything below are in NRI residency and RNOR rules, and the broader account-conversion choreography is in returning to India: NRE, NRO and FCNR account conversion. This guide stays narrowly on one question: exactly when each interest stream stops being tax-free, why the two answers differ, and how to avoid the timing traps that turn a clean transition into a needless tax bill.

What follows is the reasoning, not just the rule: why NRE keys off FEMA residency and FCNR keys off income-tax residency, why that single difference matters in rupees, the redesignation timing trap that catches people who delay, how the RFC account converts FCNR and NRE money into a tax-free landing pad through the RNOR window, and a full worked example with figures. An "Edge cases" section handles the cumulative-deposit trap, the year-of-return debate, and the re-emigration question.

Two exemptions, two different triggers

Start with the wording, because the whole guide turns on it.

NRE interest is exempt under Section 10(4)(ii) of the Income Tax Act, 1961. Read the clause carefully and the condition is not about your income-tax residency at all. The exemption is available to a person resident outside India as defined under the Foreign Exchange Management Act, 1999, or a person who has been permitted by RBI to maintain the account. In other words, the exemption is tied to your FEMA status. While you are a person resident outside India, NRE interest is exempt. The instant you stop being a person resident outside India, the exemption falls away. There is no mention of "non-resident" or "not ordinarily resident" in the income-tax sense. The hook is FEMA, and only FEMA.

FCNR interest is exempt under Section 10(15)(iv)(fa) of the Income Tax Act, 1961. This clause is worded differently. It exempts interest payable by a scheduled bank on deposits in foreign currency where the depositor is a person resident outside India within the meaning of FEMA, or a person who has been permitted by the Reserve Bank of India to maintain the account. Crucially, the long-settled reading, reflected in how banks and CAs apply it, is that the exemption survives for a depositor who has become Resident but Not Ordinarily Resident (RNOR), because such a person is permitted to continue holding the deposit to maturity and the income-tax treatment of foreign-source income for an RNOR keeps it outside the Indian net. The practical, near-universal position is that FCNR interest stays exempt while you are a non-resident or an RNOR, and becomes taxable only when you become an ordinary resident.

So the two exemptions are not the same shape. One ends with your FEMA status. The other extends into your RNOR years. That is the entire reason a returning NRI gets two different answers on two deposits that look identical.

Hold the distinction in plain language. NRE interest: tax-free only while you are a non-resident under FEMA. Lose FEMA non-residency, lose the exemption. FCNR interest: tax-free while you are a non-resident or an RNOR. Keep RNOR, keep the exemption, until the deposit matures or you turn ROR.

NRE: the exemption dies the day FEMA says you are resident, not at year-end

Here is the part that trips up almost everyone, including people who are careful about the income-tax day count.

Under FEMA, you become a person resident in India based largely on your intention and the purpose of your stay, not on a tidy day count. If you have returned to take up employment, to start or join a business, or for any purpose that signals you intend to stay for an uncertain period, you are a resident under FEMA from the day you arrive with that intention. There is no 182-day waiting period to earn residency back. You land meaning to stay, you are a FEMA resident that day.

The Income Tax Act works on a completely different clock. It counts your days in the financial year, and in the year you return you may well still be a non-resident for income tax (if your days in India are low enough), and in the years after that you are typically RNOR. This is the famous mismatch: you can be a resident under FEMA and simultaneously a non-resident or RNOR under the Income Tax Act in the same period.

Now apply the two definitions to Section 10(4)(ii). The clause keys off FEMA. So the NRE exemption ends when your FEMA status flips, which is on arrival with intent to stay, not when your income-tax residency changes. NRE interest credited after the date you become a FEMA resident is taxable, even if you are still a non-resident or RNOR for income tax that year. That is the trap. People reason "I am still RNOR, so all my old exemptions hold," and for FCNR that reasoning is correct, but for NRE it is not, because NRE never depended on your income-tax residency in the first place.

There is one consequence that flows straight from this. Because the exemption ends on a FEMA event, not at March 31, the interest splits within the financial year of return: NRE interest credited up to the date you became a FEMA resident is exempt, and interest credited after that date is taxable. On a recurring credit this is messy but mechanical. On a cumulative deposit that pays only at maturity, it is genuinely awkward, which the edge-cases section handles.

The honest framing of the year-of-return question is that there is a minority professional view, and it is worth naming rather than hiding. FEMA's definition of "person resident outside India" itself refers in part to residence in the preceding financial year, so a strand of opinion argues that NRE interest can stay exempt through the whole financial year of return, until the next April, even though you are clearly a FEMA resident from arrival. This is a genuinely debated point, with tribunal-level friction exactly because the FEMA and income-tax definitions do not line up. The conservative and far more commonly applied position, and the one assessing officers use, is that the NRE exemption ends when you become a resident under FEMA, on arrival. For planning, treat NRE interest as taxable from your return date. If your year-of-return NRE interest is large enough to be worth fighting over, get a CA to take a written position rather than relying on the optimistic reading. The residency mechanics behind all of this are in NRI residency and RNOR rules.

FCNR: the exemption can ride through RNOR all the way to maturity

FCNR(B) gets the gentle treatment, and it comes from two separate rules pulling in the same direction.

The RBI rule is a banking permission. An existing FCNR(B) deposit can run until its original maturity at the contracted rate of interest, even after you become a resident. You do not have to break it the week you land, and you do not forfeit the dollar or pound rate you locked. For every purpose other than honouring that rate, the bank treats the deposit as a resident deposit from your return date, but the deposit itself stays alive at its old rate until it matures.

The income-tax rule is the exemption. Because Section 10(15)(iv)(fa) extends to a person who is not ordinarily resident, the interest on that FCNR deposit stays exempt while you hold RNOR status. Put the two rules together and you get the planning prize: the deposit keeps running at its locked rate, and the interest keeps running tax-free, for as long as you remain RNOR, which for most genuine returnees is two to three financial years.

This is precisely where FCNR diverges from NRE. The NRE exemption looked at FEMA and ended on arrival. The FCNR exemption looks at income-tax residency and survives all the way through your RNOR window. Same return date, two deposits, two completely different lifespans for the tax break.

The exemption does end, and it ends hard. Once you become Resident and Ordinarily Resident (ROR), FCNR interest is fully taxable, added to your total income and taxed at your slab rate, with TDS applying like any other resident deposit. Running the deposit to maturity does not extend the exemption past your RNOR window; only your residency status does. So the clean move is to line up the FCNR maturity to fall inside your RNOR years, take the exempt interest, and then roll the proceeds into a Resident Foreign Currency (RFC) account, which carries the same exemption clause forward for whatever remains of your RNOR period. The deposit-side detail is in FCNR deposits explained, and the savings-versus-deposit comparison is in NRE FD vs FCNR FD.

The redesignation timing trap

Now the part that does the actual damage, because it is not a tax-law subtlety, it is an administrative one.

NRE, NRO and FCNR accounts exist for a person resident outside India under FEMA. The "NR" in each name is the eligibility condition, not branding. The moment your FEMA status flips to resident, you stop satisfying that condition, and the accounts are technically the wrong accounts to be holding. The law requires you to redesignate them: the NRE savings or current account becomes a resident rupee account (or its balance moves to an RFC account), and the NRO account becomes an ordinary resident account.

Two facts about redesignation cost people money.

First, the duty to inform the bank sits with you, not the branch. Banks have no feed from the immigration system and will not redesignate your accounts on their own. The legal duty to notify the bank of your changed status is yours, and the working norm, repeated across bank policies, is to do it within 30 days of becoming a resident. Until you tell them, the accounts keep running with their old labels, which means every day you hold an NRE account after becoming a FEMA resident is a day of technical FEMA contravention.

Second, and this is the trap that actually generates the tax bill: failing to inform the bank does not defer the change in your tax status. The exemption under Section 10(4)(ii) ended when you became a FEMA resident, regardless of what the account is still labelled on the bank's system. So if you forget to redesignate for a year, the bank may keep crediting NRE interest gross, treating it as exempt, while in the eyes of the Income Tax Act that interest has been taxable the whole time. You then face the worst of both: a FEMA contravention for holding the wrong account, and a pile of NRE interest you never declared and never paid tax on, surfacing later through your Annual Information Statement and Form 26AS or a notice. The fix is always the same and always cheaper done early: redesignate promptly, and declare the post-residency NRE interest as taxable in the correct year.

The timing also matters across the March 31 boundary. Because the NRE exemption ends on a FEMA date inside the financial year, a stale NRE account that drifts across year-end makes the tax-free-versus-taxable split on your interest far harder to draw cleanly when you file. The practical rule: pin your FEMA residency date, tell the bank in writing within 30 days, and do not let the redesignation slide into the next financial year if you can help it. If you are coming at this from the opposite direction, the mirror-image process when you first left India is in converting a resident account to NRO, and the broader return sequence is in returning NRI account conversion.

The RFC account: how to carry the FCNR exemption forward and rescue the NRE money

This is where the two streams converge on one good answer.

When you redesignate, your NRE balance and your maturing FCNR proceeds have to go somewhere. The default the bank reaches for is a resident rupee account, which forces you to convert foreign currency to rupees on a date you did not choose and surrenders all further foreign-currency exposure. The better landing pad for most returnees with a meaningful foreign-currency corpus is a Resident Foreign Currency (RFC) account, governed by the Foreign Exchange Management (Foreign Currency Accounts by a Person Resident in India) Regulations, 2015, the notification practitioners call FEMA 10(R).

The RFC account does three things that matter here. It lets you hold USD, GBP, EUR and other freely convertible currencies inside India without forced rupee conversion. It is freely repatriable, both principal and interest, with no per-year ceiling, so if you may send money abroad again you keep that option frictionless. And, the point for this guide, RFC interest is exempt under Section 10(15)(iv)(fa) while you are RNOR, the same clause that exempts FCNR interest.

That shared clause is the mechanism. When an FCNR deposit matures inside your RNOR window and you roll the proceeds into RFC, you are not starting a new exemption, you are carrying the same exemption forward under the same section for whatever remains of your RNOR period. The foreign currency stays foreign currency, and the interest stays tax-free, until you turn ROR.

You qualify to open an RFC account once you have been resident outside India for a continuous period of not less than one year and have become a resident again, which anyone genuinely abroad for several years clears comfortably. One administrative wrinkle to flag: the exemption is not automatic at the bank's end. Banks default to deducting TDS, so you must inform the branch in writing that you are RNOR and claim the exemption on your RFC and FCNR interest, or you will be chasing a refund at filing time. The full mechanics of the account, including the credits you can route through it and the 401k timing angle, are in the RFC account explained.

One caution so you do not over-claim. The NRE money you move into RFC keeps its foreign-currency character and, while you are RNOR, its RFC interest is exempt under 10(15)(iv)(fa). That does not retroactively un-tax the NRE interest credited between your return date and the redesignation; that interest was taxable under the rule above. RFC fixes the future, from the day the balance lands there. It does not rewrite the past.

Worked example: same return, two very different interest streams

Numbers make the split concrete, so put a real returnee on a timeline.

Anjali returns from Chicago to Bengaluru on June 1, 2026, to take a permanent job, after eleven straight years as a non-resident. She returns intending to stay, so she is a resident under FEMA from June 1, 2026. Having been non-resident in 9 of the last 10 financial years, she is RNOR for FY 2026-27, and on her day counts she expects to stay RNOR through FY 2028-29, becoming ROR from FY 2029-30.

On arrival she holds two deposits:

• An NRE fixed deposit of Rs 30,00,000 at 7%, interest credited at the end of each financial year.
• An FCNR(B) deposit of USD 60,000 at 4.5%, interest paid at maturity, maturing March 15, 2028, which falls inside her RNOR window.

The NRE deposit. The exemption under Section 10(4)(ii) ends on June 1, 2026, the day she becomes a FEMA resident. For FY 2026-27, the NRE interest splits at that date. The full-year interest at 7% on Rs 30,00,000 is Rs 2,10,000. Roughly two months (April and May) fall in the exempt, pre-residency window, about Rs 35,000, and the remaining ten months, about Rs 1,75,000, are taxable as ordinary income at her slab rate. She also redesignates the NRE deposit; in practice she moves the Rs 30,00,000 balance into an RFC account in dollars (or keeps it as a resident rupee deposit if she needs rupees), and tells the bank in writing within 30 days. From FY 2027-28 onward, the entire interest on that balance, whether sitting in a resident rupee FD or as RFC interest, is taxable if she has converted to rupees, or exempt as RFC interest under 10(15)(iv)(fa) while she remains RNOR if she moved it to RFC. The lesson is stark: the NRE break ended within weeks of landing, not at the RNOR boundary.

The FCNR deposit. Completely different outcome. The interest on USD 60,000 at 4.5% is about USD 2,700 a year, roughly Rs 2,24,000 a year at about Rs 83 per USD. Because the deposit matures on March 15, 2028, inside her RNOR window, and FCNR interest is exempt under Section 10(15)(iv)(fa) for an RNOR, the entire interest across the whole term stays tax-free. She does not break the deposit, she lets it run to maturity at the contracted 4.5%, and at maturity she rolls the USD 60,000 plus interest into her RFC account, where it keeps earning exempt interest for the rest of her RNOR period. Over the roughly two-year run to maturity, that is on the order of Rs 4,48,000 of interest kept entirely outside the Indian tax net.

The crossover. From FY 2029-30, Anjali becomes ROR. Both exemptions are now gone. The RFC interest (on both the former NRE balance and the matured FCNR proceeds) turns taxable at her slab rate with TDS, her worldwide income enters the Indian net, and Schedule FA foreign-asset reporting begins for the foreign accounts and assets she still holds.

The counterfactual that shows the cost of getting it backwards. Suppose Anjali had assumed the intuitive, wrong thing: that because she was still RNOR, both deposits stayed tax-free, and she therefore never declared the NRE interest. The roughly Rs 1,75,000 of post-residency NRE interest in FY 2026-27, plus another full Rs 2,10,000 a year for any later years she left the NRE balance running unconverted, would all have been taxable income she failed to report. At a 30% marginal rate that is roughly Rs 52,500 of tax on the first year alone, before interest under Sections 234B and 234C for short-paid advance tax and before any penalty, all surfacing later through her AIS. Meanwhile, she might also have broken the FCNR deposit early in a panic to "convert everything to rupees," forfeiting the locked 4.5% dollar rate and converting at a single day's exchange rate, and crystallising into a rupee FD whose interest is then fully taxable as Indian-source income even while RNOR. The mistake runs in both directions: taxing nothing when NRE should have been taxed, and destroying the FCNR exemption that did not need to be touched.

Edge cases that change the answer

A cumulative FCNR deposit maturing after you turn ROR. A deposit that pays all its interest at maturity, maturing in or after the financial year you become ROR, can have its entire accrued interest taxed in that one year, because the exemption depends on your status when the interest is received. A single maturity date landing one financial year too late can drag years of interest into a taxable year. Where you have the choice, prefer a maturity inside the RNOR window, or a payout structure that credits interest as it accrues while you are still RNOR.

The year-of-return NRE split. As covered above, there is a minority view that NRE interest stays exempt through the entire financial year of return because of how FEMA defines "person resident outside India" by reference to the prior year. The conservative, commonly applied position is that the exemption ends on the FEMA residency date, on arrival. Treat NRE interest as taxable from your return for planning, and take written advice if the year-of-return amount is material.

You took a job in India but your family is still abroad. FEMA looks at your intention and the purpose of your stay, not where your spouse and children physically sit. If you returned to take up employment for an uncertain period, you are a FEMA resident from arrival, your NRE exemption ends from that date, and you redesignate accordingly.

You forgot to inform the bank for a year and the NRE interest kept being credited gross. The exemption ended when you became a FEMA resident, not when the bank found out. Regularise promptly: redesignate now, and declare the post-residency NRE interest as taxable in the correct years, paying the tax with applicable interest. Do not compound a FEMA contravention by leaving the account mislabelled once you know.

You return, then re-emigrate within a year or two. If your stay turns out short and you genuinely become a non-resident again under FEMA, your status can flip back, and so can the account labels and the NRE exemption. It is messy mid-stream and warrants specific advice, but the general rule is that the labels and the Section 10(4)(ii) eligibility follow your current FEMA status both ways.

Joint NRE deposit with a resident. The exemption analysis follows the holder's status. On redesignation, the holding pattern interacts with the change of status; for how joint holdings behave, see joint accounts and mandates for NRIs.

Interest already credited and TDS already deducted on FCNR while RNOR. If the bank deducted TDS on FCNR interest that was actually exempt because you were RNOR, you reclaim it by filing the exemption position in your return; lodge a written RNOR declaration with the branch to stop future deductions. The TDS-and-refund mechanics are in TDS for NRIs and refunds.

The closing read

For the returning NRI the single most useful thing to fix in your head is that NRE and FCNR are not the same switch. NRE interest is exempt only under Section 10(4)(ii), only while you are a person resident outside India under FEMA, and that exemption ends the day you land with intent to stay, not at the RNOR boundary and not at year-end. FCNR interest is exempt under Section 10(15)(iv)(fa) for a non-resident or an RNOR, so an existing FCNR deposit can run tax-free all the way through your RNOR window until it matures. Treat them the same and you will get one of them badly wrong.

The honest read on what actually goes wrong is that it is rarely the tax law and almost always the admin around it. The two recurring mistakes are mirror images. People assume their NRE interest stays tax-free because they are still RNOR, never redesignate, never declare it, and carry both a FEMA contravention and an undeclared-income problem that surfaces through their AIS. And people panic in the other direction, break a perfectly good FCNR deposit to convert everything to rupees on day one, forfeiting the locked rate, freezing the exchange rate on a date they did not choose, and destroying an exemption that would have run for years. Neither is subtle. Both are avoidable.

So the play is simple. Pin your FEMA residency date, tell every bank in writing within 30 days, redesignate the NRE balance promptly (into an RFC account if you want to keep foreign currency and the RNOR exemption, into rupees only if you genuinely need rupees), and leave your FCNR deposits running to maturity, ideally maturing inside your RNOR window, then roll them into RFC. The one number genuinely worth paying a professional to get right is your RNOR-to-ROR crossover year, computed on your day counts under Section 6, because that is the date the FCNR and RFC exemptions switch off and Schedule FA begins. Get that date right and sequence your maturities and conversions around it, and the difference between the careful version and the careless one is, for most returnees with a real corpus, comfortably into six figures of avoidable tax and lost rate. For the full account-conversion choreography see returning NRI account conversion, and for building and holding the corpus once it is settled, building an India corpus as an NRI.

This guide is general information, not personalised financial, tax or legal advice. FEMA residential status, RNOR eligibility and the tax treatment of account interest depend on your specific day counts, intention and facts, and rules can change. The NRE interest exemption sits in Section 10(4)(ii) and the FCNR interest exemption in Section 10(15)(iv)(fa) of the Income Tax Act, 1961, both read against the "person resident outside India" definition in the Foreign Exchange Management Act, 1999; the treatment of NRE interest in the year of return is debated. Verify the current text of these provisions, confirm your residency status under Section 6, and consult a qualified chartered accountant or your bank before redesignating accounts, breaking or rolling a deposit, opening an RFC account, or relying on any exemption described here.
