The Expensive Investing Mistakes NRIs Make Again and Again, and What Each One Actually Costs in Rupees

A reader in Toronto sent me his portfolio last year and asked why his returns felt so much worse than the index suggested they should be. The answer was not the market. He had Rs 60 lakh sitting in an NRO fixed deposit bleeding 31.2% TDS every year, Rs 18 lakh in Indian mutual funds that his Canadian accountant had flagged as a reporting nightmare, two flats in Pune that he could neither rent profitably nor sell easily, and a ULIP a relative had sold him in 2019 that had returned less than his savings account. Not one of those was a bad market call. Every one was a structural mistake, the kind that compounds quietly for years before you notice.

The 30-second answer: The most expensive NRI investing mistakes are structural, not market-timing. Leaving foreign savings in an NRO account costs 31.2% TDS versus tax-free NRE interest. US and Canadian NRIs buying Indian mutual funds trigger the PFIC regime, with effective tax often above 40% of the gain. Over-weighting Indian property locks capital into a 2% to 4% net yield illiquid asset. ULIPs sold as investments carry 5 to 10 years of charges. Other recurring errors: ignoring currency mismatch with your goals, not claiming DTAA relief via Form 67 (deadline 31 March of the assessment year), and forgetting Schedule FA after becoming an ROR, which carries a Rs 10 lakh per-asset penalty under the Black Money Act.

This guide is not about which fund to buy. It is about the recurring, structural mistakes that cost NRIs the most, ranked roughly by how much money they quietly drain, with the rupee cost of each and the specific fix. If you already know your NRE from your NRO and your RNOR from your ROR, good; this goes a layer deeper than the definitions. Where the answer changes by country, I say so, because a mistake that is harmless for a Dubai resident can be financially serious for someone in Texas.

Leaving foreign savings in NRO instead of NRE, and paying 31.2% for the privilege

Start with the single most common and most pointless mistake, because it costs real money every year you make it. Many NRIs open one account when they move abroad, often an NRO account because it was the easiest to convert from an old resident savings account, and then park everything there: salary remittances, savings, the lot. That is backwards.

The distinction matters because of how interest is taxed. Interest on an NRE account and on an FCNR deposit is fully exempt from Indian income tax under Section 10(4)(ii), and no TDS is deducted. Interest on an NRO account is taxable in India, and the bank deducts TDS at 30% plus a 4% cess, which works out to 31.2% for most NRIs, from the very first rupee, with no basic exemption applied at source. There is no soft entry, no Rs 2.5 lakh or Rs 4 lakh free band the way a resident gets; the deduction starts immediately.

Put a number on it. Suppose you remit savings and hold Rs 50,00,000 in a fixed deposit at 7%. That earns Rs 3,50,000 a year in interest. In an NRO account, the bank deducts 31.2% TDS, Rs 1,09,200, before the money reaches you. You can claim part of it back by filing a return, but only the excess over your actual liability, and if your other Indian income is low you will still wait the better part of a year for the refund. Hold the identical deposit in an NRE account and the interest is Rs 3,50,000, tax-free, no TDS, no refund chase. The mistake costs you the time value of Rs 1,09,200 every single year at minimum, and the full amount permanently if your slab rate would have eaten it anyway.

The rule is simple and worth following exactly. Money you earn abroad and remit home belongs in NRE or FCNR, where it is fully repatriable and the interest is tax-free. The NRO account is for money that arises in India, rent, dividends, a pension, the sale proceeds of an inherited asset, because that income is taxable in India no matter which account it lands in. Using NRO as your default savings account, when the money came from your foreign salary, hands the government a 31.2% cut on income it had no claim to. If you are already in this position, you can move funds and you can file Form 10F with a Tax Residency Certificate to apply a lower DTAA rate on NRO interest, often 10% to 15% instead of 30%, but the cleaner fix is to stop feeding NRO in the first place. The mechanics of which account does what are in the NRE, NRO and FCNR accounts guide.

Buying Indian mutual funds as a US or Canada person, and walking into the PFIC trap

This is the mistake that can turn a perfectly good investment into a tax disaster, and it catches NRIs precisely because in India mutual funds are the sensible default. For a resident, or for a UK or UAE NRI, they are. For a US person, meaning a citizen, green card holder, or US tax resident, an Indian mutual fund is a Passive Foreign Investment Company (PFIC) under US tax law, and the consequences are severe.

Every Indian equity, debt, or hybrid mutual fund meets the PFIC definition because more than 75% of its income, or 50% of its assets, is passive. The moment a US person holds one, three things follow. First, you must file Form 8621 for each individual fund you hold, every year, a meaningful compliance burden if you own a dozen folios. Second, under the default Section 1291 regime, when you sell or receive an "excess distribution", the IRS pretends the gain accrued evenly across your entire holding period, taxes each prior year's slice at the highest ordinary rate for that year, and then adds compounded interest for the delay. Third, the combined tax and interest commonly exceeds 40% to 50% of the total gain on a fund held for several years, far more than the 12.5% you would have paid in India.

Here is what that does to a real holding. A US-based NRI invests Rs 20,00,000 in Indian equity funds and sells eight years later for Rs 50,00,000, a gain of Rs 30,00,000. In India, the long-term tax under Section 112A would be 12.5% on the gain above Rs 1.25 lakh, roughly Rs 3,59,000. In the US under the default PFIC regime, that Rs 30,00,000 gain is sliced across eight years, each slice taxed at up to 37% and loaded with interest, so the US bill alone can land near Rs 12,00,000 to Rs 15,00,000 before any foreign tax credit, and the credit is awkward to apply against the spread-back mechanism. The same Rs 30 lakh gain that costs an Indian resident Rs 3.6 lakh can cost a US NRI three to four times that. Had the same person held Indian exposure through a US-domiciled ETF instead, the gain would have been ordinary US long-term capital gains, taxed at 15% to 20% with none of the PFIC penalty.

The fix depends on your country. US persons should avoid Indian mutual funds and ULIPs entirely; hold Indian-listed stocks directly, which are not PFICs, use US-domiciled ETFs that track Indian or emerging-market equities, or keep the India allocation in NRE fixed deposits where the return is tax-free in India and simply reported as interest in the US. Canadian residents do not face PFIC but must report foreign holdings above CAD 100,000 on form T1135, and Indian mutual fund gains are taxable in Canada, so the calculus still favours simplicity. UK and UAE residents have no PFIC equivalent and can hold Indian mutual funds normally, subject to UK reporting-fund rules that affect the rate. The eligibility mechanics and the full PFIC overlay are in the NRI mutual fund eligibility guide, and the broader country-by-country logic is in tax-efficient investing for NRIs.

Pouring the corpus into Indian property because it "feels safe"

Real estate is the emotional default for NRIs, and over-weighting it is the costliest allocation mistake I see, precisely because it does not look like a mistake. A flat is tangible, it is in India, family can use it, and the headline appreciation story is seductive. The problem is what the asset actually does inside a portfolio.

The numbers rarely justify the conviction. Residential rental yields in India run 2% to 4% net after maintenance, society charges, vacancy, and the cost of managing a property from another continent. Compare that with an NRE fixed deposit at around 7%, tax-free, or a listed REIT yielding mid-to-high single digits with full liquidity. The property bull case rests entirely on capital appreciation, which is real in some micro-markets and flat for a decade in others, and which you cannot access without selling. And selling is where the second cost lands: as an NRI you pay 12.5% long-term capital gains with no indexation option that residents get, the buyer must deduct TDS under Section 195 (often over-withholding on the entire sale value), and finding a buyer for a mid-market flat can take months.

See the gap on a single decision. An NRI puts Rs 1,00,00,000 into a Pune flat. Net rent at 3% is Rs 3,00,000 a year, less TDS the tenant must deduct at 31.2% on rent, less the cost of a property manager and occasional vacancy, so the cash in hand is closer to Rs 1,80,000 to Rs 2,00,000. The same Rs 1 crore in an NRE deposit at 7% yields Rs 7,00,000 tax-free with zero management and instant liquidity. Even if the flat appreciates 6% a year, you cannot spend the appreciation, you carry concentration risk in a single illiquid asset, and the exit is taxed and slow. The counterfactual over ten years: the NRE deposit compounds to roughly Rs 1,96,00,000 tax-free and fully liquid; the flat needs sustained 6%-plus appreciation just to match it after the low net yield, transaction costs, and the no-indexation tax on exit are counted.

This is not an argument against ever owning Indian property. It is an argument against making it 60% or 70% of your net worth because it feels safer than markets it usually is not. The fix is allocation discipline: decide what fraction of the corpus belongs in real estate before you fall for a specific flat, cap it, and meet the rest of your India exposure through liquid instruments. If you want property economics without the illiquidity and the management headache, listed REITs and fractional commercial ownership exist. Build the target weights deliberately using the NRI portfolio asset allocation guide and the India corpus guide.

Buying a ULIP because someone called it an investment

Insurance sold as investment is the most reliable way to lose money slowly while believing you are saving it, and NRIs are a favourite target for the pitch because they are perceived as cash-rich and far from the fine print. A Unit Linked Insurance Plan bundles a thin layer of life cover with a market-linked investment, and the bundling is the problem: you pay for both, and the charges in the early years are brutal.

A ULIP layers premium allocation charges, policy administration charges, fund management fees, and mortality charges, and surrender penalties bite for the first five years, which is the mandatory IRDAI lock-in. In the early years a large slice of your premium never reaches the market at all; it is consumed by charges and the cost of the insurance. The result is that the internal rate of return on most ULIPs over their first decade trails a plain index fund by a wide margin, and trails it by even more once you account for the fact that you could have bought far more life cover, far more cheaply, through a pure term plan and invested the difference yourself.

Put it in rupees. Say you commit Rs 2,00,000 a year to a ULIP for ten years, Rs 20,00,000 in total. Between allocation, administration, mortality, and fund-management charges, it is common to lose 10% to 15% of the early premiums to costs before any market return, and surrendering in year three or four can return less than you paid in. Now the alternative: a term plan giving Rs 1 crore of cover costs roughly Rs 15,000 to Rs 25,000 a year for a healthy NRI in their thirties, leaving about Rs 1,80,000 a year to invest. Put that into a low-cost equity index fund returning, say, 10%, and over ten years the difference between the ULIP's drag-laden return and the term-plus-index approach can easily exceed Rs 5,00,000 to Rs 8,00,000 on the same outflow, while giving you the same or better life cover. The ULIP also carries a tax sting that is easy to miss: from 1 April 2026, ULIPs with annual premium above Rs 2.5 lakh lose the Section 10(10D) exemption and are taxed as capital gains at 12.5%, and surrendering before the five-year lock-in pulls the payout into your slab income and reverses any 80C deduction you claimed.

The fix is the oldest rule in personal finance: separate insurance from investment. Buy a clean term plan for protection, buy low-cost funds or deposits for growth, and never let a relationship manager who earns commission on the bundle tell you the two belong in one product. If you already hold a ULIP, do the math on surrendering after the lock-in versus continuing; sometimes the charges are now behind you and exiting is wasteful, but often the honest move is to stop feeding it. The full economics are in the ULIPs for NRIs guide.

Ignoring the currency your goals are actually in

This is the subtle one, the mistake that does not show up on any single statement but quietly undermines your plan. NRIs earn in dollars, pounds, or dirhams and instinctively invest at home in rupees, then discover that the currency their money grows in does not match the currency their goals are priced in. The mismatch cuts both ways and most people only think about it once.

If your goal is to return to India and retire there, your liabilities are in rupees, and a rupee-heavy portfolio is correctly matched; the rupee's long slide against the dollar, which has averaged roughly 3% to 4% a year of depreciation over decades, actually works in your favour because each future dollar buys more rupees. But if your goal is to stay abroad, fund a child's education in the US or UK, or keep optionality about where you settle, then a portfolio concentrated in rupee assets carries a hidden currency risk: that 3% to 4% annual rupee depreciation is a 3% to 4% annual drag on the dollar value of your India holdings, and it can quietly eat much of the higher nominal return that tempted you to invest in India in the first place.

See it on a number. You invest Rs 50,00,000 in Indian equities, which at Rs 83 to the dollar is about USD 60,000. Over five years the rupee portfolio grows 60% to Rs 80,00,000, a satisfying result on paper. But the rupee has slipped to, say, Rs 96 to the dollar over the same period. Your Rs 80,00,000 is now worth about USD 83,000, a gain of around 38% in dollar terms, not 60%. If your child's tuition bill is in dollars, the 22-percentage-point gap between the rupee return and the dollar return is the cost of the currency mismatch, and it was invisible until you converted.

The fix is to match the currency of your assets to the currency of your goals, not to your nationality or your nostalgia. Money earmarked for India-based goals can sit in rupee assets and even benefit from the depreciation. Money earmarked for goals priced in your host-country currency should largely stay in that currency, in host-country investments, with India exposure sized as a deliberate, smaller allocation rather than a default. This is a planning decision, not a market call, and it is covered in the asset-allocation framework in the NRI portfolio asset allocation guide.

Paying tax twice because you never filed Form 67

NRIs who pay tax in two countries on the same income, common with Indian rental income, capital gains, or dividends that are also taxable in the host country, are entitled to relief under the Double Taxation Avoidance Agreement, but the relief is not automatic. To claim a foreign tax credit on your Indian return for tax paid abroad, or to have your host country credit the Indian tax, you have to do the paperwork, and the single most common failure is missing Form 67.

Form 67 is the form that supports a foreign tax credit claim under Sections 90, 90A, or 91 on your Indian return. The rule that trips people up is the deadline: Form 67 must be filed on or before 31 March of the assessment year, which is the end of the assessment year, and crucially it must be filed before you file the return it supports, whether that return is on time under Section 139(1) or belated under 139(4). Miss the Form 67 deadline and the credit can be denied outright, meaning you pay the full Indian tax with no offset for what you already paid abroad, the textbook definition of being taxed twice. Note that Form 67 is being renumbered as Form 44 under the Income Tax Act 2025, effective 1 April 2026, so for returns filed from that date you will look for the new number.

The cost of getting this wrong is exactly the size of the credit you forfeit. Say you earned Rs 8,00,000 of Indian rental income, paid Rs 1,60,000 of Indian tax on it after the standard deduction, and your host country taxes the same income and would have credited that Rs 1,60,000. File Form 67 on time and you pay tax once, net. Forget it, and depending on the direction of the relief you can end up paying Rs 1,60,000 in India and the host-country tax on top, with no credit, simply because a form was late. There is no discretion to fix it after the deadline in most cases. The fix is calendar discipline: if you have any foreign-taxed income flowing into your Indian return, file Form 67 first, well before 31 March of the assessment year. The full mechanics are in the foreign tax credit and Form 67 guide.

Forgetting Schedule FA the year you become an ROR

This is the mistake with the most disproportionate penalty relative to the effort it takes to avoid, and it ambushes returning NRIs specifically. As long as you are a non-resident, you generally do not report your foreign assets to India. The moment you return and your status flips to Resident and Ordinarily Resident, usually in the year after you come back, you must disclose every foreign asset in Schedule FA of your Indian return: foreign bank accounts, brokerage accounts, pension and retirement accounts, foreign mutual funds and stocks, foreign property, and any beneficial interest in an overseas entity.

The reason this matters so much is the penalty regime sitting behind it. Schedule FA is an informational disclosure, but failing to make it triggers the Black Money (Undisclosed Foreign Income and Assets) Act, which imposes a penalty of Rs 10 lakh per undisclosed asset, regardless of whether any Indian tax was even due on that asset. The penalty is for the non-disclosure itself, not for any tax evaded. There is a safe-harbour for small foreign movable assets up to Rs 20 lakh that does not attract the penalty, and the Finance Bill 2026 proposed a one-time six-month disclosure window for small taxpayers, but the headline risk is real and large.

The arithmetic is unforgiving. A returning NRI from the US who keeps a 401(k), a brokerage account, and two dormant bank accounts has four foreign assets. Forget to list them in Schedule FA in the first ROR year and the exposure is Rs 10 lakh times four, Rs 40 lakh in penalties, for assets you may have fully and legitimately paid tax on abroad. The income on them might have generated only a few lakh of Indian tax; the penalty for not mentioning them dwarfs it. Because the disclosure costs nothing and there is no tax consequence to declaring, there is simply no upside to omitting an asset. The fix is mechanical: in your first ROR year, inventory every foreign account and holding, including the dormant and the trivial, and report all of them in Schedule FA. The detailed walkthrough, including the high-water-mark and peak-balance fields people get wrong, is in the Schedule FA foreign asset reporting guide.

Buying whatever the NRI-targeted sales pitch is selling

The last mistake is not a product, it is a posture. NRIs receive a steady stream of pitches engineered specifically for them: pre-launch property in a "guaranteed appreciation" township, a "capital-protected" market-linked insurance plan, a fractional-ownership deal with a glossy brochure and a soft lock-in, a portfolio management service promising market-beating returns for a 2% fee plus a profit share. The common thread is that the product is designed around the commission to the seller, not the return to you, and the NRI angle is a marketing wrapper because NRIs are seen as wealthy, distant, and unlikely to scrutinise the fine print from another time zone.

The tell is almost always in the costs and the lock-in, not the headline number. A "guaranteed 12% return" property scheme is a real-estate company borrowing from you at 12% with your own flat as the only collateral, and "guaranteed" returns are not guaranteed by anyone with a balance sheet you can chase. A capital-protected ULIP-style plan protects capital by giving you almost no equity exposure while charging you equity-product fees. A PMS or AIF with a 2% management fee and a 20% profit share has to beat a cheap index fund by more than 2% a year just to break even with you, and most do not. Each of these costs you the gap between what you were sold and what a boring, low-cost alternative would have done, and over a decade that gap routinely runs into many lakhs on a meaningful corpus.

The fix is a default of scepticism and a habit of asking three questions before any NRI-targeted product. What does this cost me per year, all in, including the charges that are not in the headline. How quickly and at what cost can I get my money out. And what does the plainest possible alternative, a term plan, an index fund, an NRE deposit, return on the same money over the same period. If the salesperson cannot answer the first two clearly, that is the answer. The honest framing across every section of this guide is the same: the expensive mistakes are not bad market calls, they are structurally bad products and structurally bad account choices that a commission-driven pitch made attractive.

Edge cases

You are a US person who already holds Indian mutual funds. Do not panic-sell without modelling it; an immediate sale crystallises the full Section 1291 spread-back. Speak to a US-India cross-border CA about a mark-to-market or QEF election where available, or about an orderly exit, before you act. The mistake is buying more, not necessarily holding what you have while you plan the unwind.

You returned to India mid-year and are RNOR, not yet ROR. During Resident but Not Ordinarily Resident years, your foreign income is largely outside the Indian net and Schedule FA reporting of foreign assets is generally not triggered the way it is for an ROR. The expensive error is assuming RNOR lasts longer than it does; it typically covers only the first two years, after which full ROR reporting and the Black Money Act exposure begin. Track the exact year your status flips.

Your NRO TDS exceeds your real liability and you have low Indian income. You are not stuck paying 31.2%. File Form 13 for a lower-deduction certificate before large interest accrues, or file a return to claim the refund, and apply your DTAA rate with a Tax Residency Certificate and Form 10F to cut the deduction at source to the treaty rate, often 10% to 15%.

You hold a ULIP whose five-year lock-in has already passed. The worst charges are behind you, so surrendering may waste the cost you already paid. Compare the forward-looking return net of remaining charges against redeploying the surrender value into low-cost funds. Sometimes holding is the rational call even though buying it was the mistake.

The closing read

The honest read is that almost none of the money NRIs lose comes from picking the wrong stock or mistiming the market. It comes from eight structural decisions made once and left unexamined: parking foreign savings in NRO and feeding the 31.2% TDS, buying PFIC mutual funds while a US or Canada tax resident, letting Indian property swell to most of the net worth at a 2% to 4% net yield, mistaking a ULIP for an investment, ignoring the currency your goals are denominated in, skipping Form 67 and paying tax twice, forgetting Schedule FA and risking Rs 10 lakh per asset, and saying yes to whichever pitch was engineered for NRIs that quarter.

So the recommendation for the common case is unglamorous and reliable. Keep foreign earnings in NRE or FCNR and use NRO only for India-sourced income. If you are a US or Canada person, hold India through direct stocks or home-domiciled ETFs, not Indian mutual funds. Cap real estate at a deliberate fraction of the corpus rather than letting it become the corpus. Buy term insurance and low-cost funds separately, never bundled. Match the currency of your assets to the currency of your goals. File Form 67 before 31 March of the assessment year, and file Schedule FA in full from your first ROR year. The exception worth naming: if you are a UAE or Gulf resident with India-based retirement goals, several of these soften, no PFIC problem, no host-country tax to credit, and a rupee tilt that suits a rupee retirement. Everyone else should treat the list above as a checklist, not a menu. And on any large property sale, ULIP surrender, or first ROR return, that is the moment to pay a qualified cross-border CA, not to rely on a guide, this one included.
