10 Frequently Asked Questions

Part A: Tax Filing Errors (Mistakes 1--7)

These are the mistakes that happen before a single rupee changes hands. Filing errors result in lost refunds, blocked carry-forwards, and notices from the Centralized Processing Centre that can haunt you for years.

Mistake 1: Not Filing an Income Tax Return Despite TDS Being Deducted

What it is: An NRI earns interest on an NRO fixed deposit. The bank deducts TDS at 30% (plus surcharge and cess). The NRI assumes TDS settlement equals final tax payment and never files an ITR.

Why it happens: Many NRIs believe that TDS is a final settlement of their tax liability, similar to how withholding tax works in countries like the US or UK. In India, TDS is merely an advance collection mechanism. Filing an ITR is the only way to claim a refund of excess TDS.

The cost: If your total Indian income for the year is below the basic exemption limit (Rs 3,00,000 under the new regime for FY 2025-26), you are entitled to a full refund of all TDS deducted. On an NRO FD of Rs 20,00,000 earning 7% interest, TDS at 31.2% (including cess) is approximately Rs 43,680. Without filing, that refund is permanently lost. Over five years, this compounds to Rs 2,18,400 in forfeited refunds -- money that was always yours.

Additionally, under Section 234F, a belated return filed after the due date attracts a late fee of Rs 5,000 (Rs 1,000 if total income is below Rs 5,00,000). Persistent non-filing can trigger Section 148 reassessment notices.

Quick Fix: File ITR-2 every year, even if your only Indian income is NRO interest. If TDS exceeds your actual tax liability, claim the refund. Set a calendar reminder for July 31 (or the extended due date) each year. Engage a qualified CA to handle this if you are abroad.

Mistake 2: Filing the Wrong Form -- Using ITR-1 (Sahaj) as an NRI

What it is: An NRI uses ITR-1 to file their Indian tax return. The return may even be processed and an intimation issued under Section 143(1). The NRI believes everything is in order.

Why it happens: ITR-1 is the simplest form and many online filing platforms default to it. NRIs who handled their own taxes as residents continue using the same form without realizing the restriction.

The cost: ITR-1 is exclusively for Resident Individuals. An NRI or RNOR (Resident but Not Ordinarily Resident) is explicitly barred from using it. A return filed on the wrong form is a defective return under Section 139(9). The CPC issues a defective return notice giving 15 days to correct it. If not corrected, the return is treated as if it was never filed -- which means you lose your refund, lose the ability to carry forward losses, and face a late filing penalty if you refile after the due date.

Quick Fix: NRIs must file ITR-2 (if no business income) or ITR-3 (if there is business or professional income in India). Verify your residential status determination before selecting the form. Never use ITR-1 or ITR-4.

Mistake 3: Claiming the Section 87A Rebate as an NRI

What it is: Section 87A provides a tax rebate of up to Rs 25,000 (new regime, FY 2025-26) for resident individuals with taxable income up to Rs 7,00,000. NRIs claim this rebate in their ITR, reducing their tax liability.

Why it happens: Tax filing software sometimes auto-populates the rebate. NRIs who are not aware of the residency restriction assume it applies to all individual taxpayers.

The cost: The rebate is available only to Resident Individuals. When the CPC processes the return, the rebate is reversed, creating an outstanding tax demand plus interest under Section 234A/234B/234C. On an income of Rs 6,50,000, the wrongly claimed rebate of Rs 25,000 becomes a demand with interest of approximately Rs 1,000--3,000 depending on timing. More critically, it triggers a mismatch notice and potential scrutiny, consuming time and professional fees to resolve.

Quick Fix: When filing your ITR, ensure your residential status is correctly marked as "Non-Resident" or "Resident but Not Ordinarily Resident." The Section 87A rebate line should show zero. If your filing software auto-fills it, manually override it to zero before submission.

Mistake 4: Declaring the Wrong Residential Status

What it is: An NRI who spent 175 days in India during FY 2025-26 marks themselves as "Non-Resident" on their ITR. Conversely, someone who left India mid-year and spent only 100 days in India marks themselves as "Resident."

Why it happens: The 182-day rule is widely known, but the additional conditions under Section 6(1) and Section 6(6) -- including the 60-day rule for Indian citizens leaving for employment, the 120-day rule for high-income individuals, and the RNOR transition conditions -- create genuine confusion. The determination requires counting actual days of physical presence, not calendar months.

The cost: Getting residential status wrong affects every subsequent line of the return. A Resident is taxed on global income; an NRI is taxed only on Indian-sourced income. If you are actually Resident but file as NRI, you under-report global income, inviting reassessment with penalties up to 200% of tax evaded under Section 270A. If you are actually NRI but file as Resident, you may incorrectly report and pay tax on foreign income that India has no right to tax.

Quick Fix: Count your physical days in India for the financial year using passport stamps, travel records, and boarding passes. Apply the complete test under Section 6(1), then check RNOR conditions under Section 6(6). If your situation is complex (multiple trips, mid-year relocation), get a formal residential status opinion from a qualified CA before filing.

Mistake 5: Missing the Filing Due Date and Losing Loss Carry-Forward

What it is: An NRI sells mutual fund units at a capital loss of Rs 3,50,000 during FY 2025-26. They file a belated return in January 2027, four months after the July 31 due date.

Why it happens: NRIs often have limited Indian income and treat the filing as low priority. Time zone differences, lack of local CA access, and the "I will do it later" syndrome all contribute.

The cost: Under Section 139(3), capital losses (short-term and long-term) can only be carried forward if the return is filed on or before the due date under Section 139(1). A belated return under Section 139(4) permanently kills the carry-forward. That Rs 3,50,000 capital loss, which could have been set off against future capital gains over the next 8 assessment years, is gone. At a 20% tax rate on LTCG (above Rs 1,25,000 exemption), that is Rs 70,000 in future tax savings destroyed.

Additionally, belated filing attracts the Rs 5,000 late fee under Section 234F and interest under Section 234A on any tax due.

Quick Fix: Treat July 31 as a non-negotiable deadline. If you have capital losses in any year, this is especially critical. Engage your CA well in advance -- by June at the latest -- and ensure all documents (AIS, 26AS, capital gain statements, bank statements) are shared early.

Mistake 6: Not Comparing Old Regime vs. New Regime Before Filing

What it is: An NRI defaults to the new tax regime without evaluating whether the old regime would have resulted in lower tax, or vice versa.

Why it happens: The new regime (Section 115BAC) is now the default. Many NRIs assume "new" means "better." Others stick to the old regime out of habit without recalculating.

The cost: The optimal regime depends on the specific deductions and exemptions available to the NRI. An NRI paying Rs 2,00,000 in home loan interest (Section 24) on a let-out property and making NPS contributions would often save more under the old regime. Conversely, an NRI with only NRO interest and no deductions benefits from the lower slab rates of the new regime.

The difference can range from Rs 10,000 to Rs 1,50,000 or more depending on income levels and deduction profiles. Over multiple years of choosing the wrong regime, the cumulative cost is substantial.

Quick Fix: Before every filing, run a parallel computation under both regimes. Your CA or a good tax planning tool can generate a side-by-side comparison in minutes. Remember that NRIs without business income can switch between regimes every year -- there is no lock-in for non-business income.

Mistake 7: Ignoring AIS/26AS Mismatches

What it is: The Annual Information Statement (AIS) and Form 26AS show transactions that do not match what the NRI reports in their ITR. Common mismatches include mutual fund transactions, property purchases reported by registrars, high-value bank deposits, and share trading volumes.

Why it happens: NRIs often file based on their own records without downloading and cross-checking AIS/26AS. The AIS aggregates data from banks, mutual fund registrars, property registrars, stock brokers, and other reporting entities. Even errors by these entities (duplicate entries, wrong PAN tagging) show up on the NRI's AIS.

The cost: Unaddressed mismatches trigger automated notices under Section 143(1)(a) and can escalate to scrutiny under Section 143(2). The compliance burden of responding to these notices from abroad is enormous -- time, stress, CA fees, and potential penalties if the mismatch reflects unreported income.

Quick Fix: Before filing, download both AIS and 26AS from the income tax portal. Compare every line item against your actual income and transactions. If there are errors in AIS (e.g., a mutual fund SIP reported twice), use the AIS feedback mechanism on the portal to flag the discrepancy before filing. Ensure every item in AIS is either reported in your ITR or explained via feedback.

Part B: TDS Overpayment and Compliance Gaps (Mistakes 8--12)

TDS mistakes are arguably the most expensive category for NRIs because the money leaves your account before you even realize it. Banks, property buyers, and tenants are required to deduct TDS on payments to NRIs, and the default rates are punishingly high.

Mistake 8: Not Applying for a Section 197 Lower TDS Certificate

What it is: Section 197 of the Income Tax Act allows a taxpayer to apply to the Assessing Officer for a certificate authorizing lower or nil TDS deduction, where their actual tax liability is significantly lower than the statutory TDS rate.

Why it happens: Most NRIs do not know this provision exists. Banks and property buyers deduct TDS at the full statutory rate (30% on NRO interest, 20% or 12.5% on property sale proceeds) because they are legally required to unless a Section 197 certificate is presented.

The cost: Consider an NRI selling a property for Rs 1,00,00,000 with an indexed cost of Rs 85,00,000. The actual long-term capital gain is Rs 15,00,000, attracting tax of roughly Rs 1,87,500 (at 12.5%). Without a Section 197 certificate, the buyer deducts TDS at 12.5% on the entire sale consideration -- Rs 12,50,000. The NRI has now overpaid by over Rs 10,62,500 and must wait 6--18 months for a refund after filing. That is a massive cash flow hit that is entirely avoidable.

Quick Fix: Apply for a Section 197 certificate through Form 13 on the TRACES portal at least 30--45 days before the property sale transaction or before the financial year begins (for recurring income like rent or interest). Attach your computation of income, past ITRs, and tax projections. The AO typically issues the certificate within 30 days.

Mistake 9: Accepting 30% TDS on NRO Interest When DTAA Provides a Lower Rate

What it is: India has Double Taxation Avoidance Agreements with over 90 countries. Many of these treaties cap the tax rate on interest income at 10% or 15%. Despite this, banks routinely deduct TDS at 30% (plus cess) on NRO interest.

Why it happens: Indian banks follow the Income Tax Act as the default. They are not obligated to apply DTAA rates automatically. The NRI must proactively submit a Tax Residency Certificate (TRC), Form 10F, and a self-declaration to claim treaty benefits.

The cost: On NRO deposits of Rs 50,00,000 earning 7% interest (Rs 3,50,000), TDS at 31.2% (with cess) is Rs 1,09,200. Under the India-US DTAA, the rate on interest is 15%, reducing TDS to Rs 52,500. Under the India-Singapore DTAA, it is 15% as well. Under India-UAE (no specific treaty rate on interest in the older treaty), the domestic rate applies. For treaties that do provide relief, the NRI pays Rs 56,700 more in TDS annually than necessary. Over a decade, this is Rs 5,67,000 in unnecessary cash flow leakage.

Quick Fix: Obtain a Tax Residency Certificate from the tax authority of your country of residence each year. Complete Form 10F (available on the Indian income tax portal) and submit both documents, along with a self-declaration of beneficial ownership, to your bank before April 1 of each financial year. Follow up to confirm the bank has applied the lower rate.

Mistake 10: Not Submitting TRC to the Bank Every Year

What it is: An NRI submitted their TRC and Form 10F to the bank three years ago and assumes it is still valid.

Why it happens: TRCs are typically issued for one fiscal year. Banks reset their TDS parameters annually. Without a fresh TRC submission each year, the bank reverts to the default 30% rate.

The cost: Identical to Mistake 9 -- the NRI pays full domestic rate TDS instead of the treaty rate. The additional cost is the refund processing delay (typically 6--12 months after filing) and the opportunity cost of that locked-up capital.

Quick Fix: Treat TRC submission as an annual ritual. Set a recurring calendar reminder for March of each year. Obtain the new TRC, complete Form 10F, and submit to every Indian bank where you hold NRO accounts before the start of the new financial year.

Mistake 11: Not Claiming TDS Refund for Years Where Total Income Is Below Exemption

What it is: An NRI has only NRO interest income of Rs 2,50,000 during FY 2025-26. TDS of Rs 78,000 (at 31.2%) has been deducted. Their total Indian income is below the basic exemption limit of Rs 3,00,000 under the new regime. They never file an ITR to claim the refund.

Why it happens: The NRI assumes that since they are "non-resident," they cannot claim the basic exemption. Others simply do not realize that filing would produce a refund.

The cost: NRIs are entitled to the basic exemption limit just like residents. If total income is below Rs 3,00,000, the entire TDS is refundable. Forfeiting Rs 78,000 annually over five years means Rs 3,90,000 lost permanently.

Note: Even if income exceeds the basic exemption, the tax on the first Rs 3,00,000 is nil. So on income of Rs 4,00,000, tax is only on Rs 1,00,000 at 5% = Rs 5,000. If TDS was Rs 1,24,800 (31.2% of Rs 4,00,000), the refund is Rs 1,19,800. Not filing sacrifices that entire amount.

Quick Fix: File ITR-2 for every year where TDS has been deducted. Even if you think no refund is due, file anyway -- the computation may surprise you. Refunds are credited directly to the bank account linked to your PAN.

Mistake 12: Property Buyer Deposits TDS Under the Wrong Challan or Section

What it is: When an NRI sells property, the buyer is responsible for deducting and depositing TDS. The buyer uses Form 26QB (which is for resident sellers under Section 194-IA at 1%) instead of the correct procedure under Section 195 for NRI sellers (at 12.5% for LTCG or 30% for STCG, unless a Section 197 certificate applies).

Why it happens: Buyers are often unaware that the seller is an NRI. Even when they know, many CAs and property lawyers default to the simpler Form 26QB process. The buyer's CA may not specialize in NRI transactions.

The cost: TDS deposited under the wrong section does not reflect in the NRI seller's Form 26AS correctly. The NRI cannot claim credit for TDS that is tagged to the wrong section/PAN. Correcting this requires the buyer to file a TDS correction statement, which can take months. Meanwhile, the NRI faces a tax demand for the full amount, interest accumulation under Section 234B, and potential penalty proceedings.

Quick Fix: Before completing the property sale, educate the buyer on their TDS obligations for NRI transactions. The buyer must obtain a TAN, deduct TDS under Section 195, deposit it using Challan 281, and file Form 27Q (not 26QB). Provide the buyer with a copy of any Section 197 certificate. Consider having your CA coordinate directly with the buyer's CA to prevent errors.

Part C: Property Transaction Blunders (Mistakes 13--18)

Property is the single largest asset class for most NRIs in India. The stakes are high -- a single mistake on a Rs 1 crore property can cost Rs 5--15 lakhs in avoidable tax.

Mistake 13: Not Computing Both Capital Gains Options (With and Without Indexation)

What it is: For properties acquired before July 23, 2024, NRIs have two options for computing long-term capital gains: (a) 20% with indexation (using cost inflation index up to FY 2023-24), or (b) 12.5% without indexation. The NRI defaults to one method without comparing both.

Why it happens: The dual-option computation was introduced with the July 2024 budget amendment. Many NRIs and even some CAs are not fully aware of the grandfathering provision.

The cost: For properties held for a long period with significant cost inflation indexation benefit, the 20% with indexation option often produces a lower tax. For properties with moderate appreciation, the 12.5% flat rate may be better. On a property purchased in 2005 for Rs 20,00,000 and sold in 2026 for Rs 1,20,00,000, the CII-indexed cost could be approximately Rs 68,00,000, making the gain Rs 52,00,000 at 20% = Rs 10,40,000 tax. Without indexation, the gain is Rs 1,00,00,000 at 12.5% = Rs 12,50,000 tax. Choosing the wrong option costs Rs 2,10,000 in this example.

Quick Fix: For every property sale, compute capital gains under both methods. Compare the tax liability under each. Choose the option that produces the lower tax. This dual computation should be standard practice for any CA handling NRI property sales.

Mistake 14: Missing the 6-Month Deadline for Section 54EC Bond Investment

What it is: Section 54EC allows NRIs to claim exemption from long-term capital gains tax by investing up to Rs 50,00,000 in specified bonds (NHAI, REC, PFC, IRFC) within 6 months of the date of sale. The NRI misses this window.

Why it happens: Property sale paperwork, fund repatriation logistics, and general inertia cause delays. Some NRIs assume they have until the ITR filing date.

The cost: The 6-month window is absolute and non-extendable. Missing it by even one day means the entire exemption is lost. On a capital gain of Rs 50,00,000, the tax at 12.5% is Rs 6,25,000. The exemption would have saved this entire amount (or a proportionate part if the gain exceeds Rs 50,00,000).

Quick Fix: On the day of property registration, calculate the 6-month deadline and diarize it. Begin the bond application process immediately. These bonds can be purchased through designated bank branches. Do not wait until the last month -- bond issuances sometimes have periodic closures, and your bank may take time to process the application from an NRO account.

Mistake 15: Selling Under-Construction Property and Claiming Section 54 Exemption

What it is: Section 54 provides capital gains exemption when the sale proceeds of a residential property are invested in purchasing or constructing another residential property. An NRI sells property and invests in an under-construction flat, claiming Section 54 exemption.

Why it happens: The NRI assumes that booking an under-construction flat and making payments qualifies as "purchase" or "construction."

The cost: For the exemption to apply, the new property must be purchased within 2 years (or constructed within 3 years) of the sale date. If the under-construction property is not completed and possession is not received within the stipulated period, the exemption is denied. The entire capital gains tax, plus interest from the original due date, becomes payable. On a gain of Rs 40,00,000, this could mean a demand of Rs 5,00,000 in tax plus Rs 1,00,000--2,00,000 in interest.

Quick Fix: If investing in under-construction property, ensure the builder's timeline guarantees completion within the Section 54 window. Get this in writing. Alternatively, deposit the capital gain amount in the Capital Gains Account Scheme (CGAS) with a designated bank before the ITR filing due date to preserve the exemption while the construction completes.

Mistake 16: Miscounting the 24-Month Holding Period for Long-Term Classification

What it is: Since FY 2017-18, immovable property (land, building, or both) is classified as a long-term capital asset if held for more than 24 months (previously 36 months). NRIs miscount the holding period, especially when the property was acquired through inheritance, gift, or a housing society allotment.

Why it happens: For inherited property, the holding period includes the previous owner's period of holding. For property received in a housing society allotment, the date of allotment (not possession) is the acquisition date. These nuances are frequently missed.

The cost: If the holding period is miscounted as long-term when it is actually short-term, the NRI applies the 12.5% LTCG rate instead of the 30% STCG rate. The shortfall in tax, once detected, attracts interest under Section 234B and potential penalty for under-reporting income under Section 270A (50% to 200% of tax).

Conversely, if a long-term asset is mistakenly classified as short-term, the NRI overpays at 30% instead of 12.5% and forfeits the ability to claim Section 54/54EC exemptions.

Quick Fix: Determine the correct date of acquisition using the legal documents -- sale deed, allotment letter, will, gift deed, or partition deed. For inherited assets, trace back to the original owner's acquisition date. Count 24 full months from that date to determine long-term eligibility.

Mistake 17: Not Obtaining a Section 197 Certificate Before Property Sale

What it is: (Related to Mistake 8, but specifically for property transactions.) An NRI proceeds with a property sale without applying for a lower TDS certificate. The buyer deducts TDS at the full rate on the gross sale consideration.

Why it happens: NRIs often do not plan the sale far enough in advance. They decide to sell, find a buyer within weeks, and by the time they learn about Section 197, the registration is imminent.

The cost: As detailed in Mistake 8, the difference between TDS on gross consideration versus TDS on actual capital gain can be massive. On a Rs 1,50,00,000 property with a gain of only Rs 20,00,000, TDS at 12.5% on Rs 1,50,00,000 = Rs 18,75,000 versus actual tax of approximately Rs 2,50,000. The NRI is out-of-pocket by Rs 16,25,000 for 6--18 months waiting for the refund.

Quick Fix: Begin the Section 197 application process the moment you decide to sell. Ideally, apply 45--60 days before the anticipated sale date. The certificate specifies the exact amount or rate of TDS, protecting both the buyer and seller.

Mistake 18: Ignoring Advance Tax Obligations on Property Sale Capital Gains

What it is: An NRI sells a property in August 2025 and generates a capital gain of Rs 30,00,000. They do not pay any advance tax, waiting instead to settle the full liability when filing the ITR in July 2026.

Why it happens: NRIs assume TDS deducted by the buyer covers their tax liability. While TDS may cover a part (or all, if a Section 197 certificate was obtained), there are situations where additional tax is due -- especially when TDS was deposited at a lower rate or when the actual gain differs from estimates.

The cost: Under Section 234C, interest is charged at 1% per month on the shortfall in advance tax for each quarter. If Rs 30,00,000 gain generates a tax of Rs 3,75,000 and the buyer deducted TDS of Rs 2,00,000, the NRI owes Rs 1,75,000 in additional tax. Interest at 1% per month for approximately 10 months (from September 2025 to July 2026 filing) is Rs 17,500.

Quick Fix: After any property sale, immediately compute the capital gain and compare the tax liability against TDS deducted. If there is a shortfall, pay advance tax using Challan 280 within the same quarter. For sales in Q2 (July--September), advance tax for that quarter is due by September 15.

Part D: Banking and FEMA Violations (Mistakes 19--23)

FEMA violations are not just tax issues -- they carry separate penalties under the Foreign Exchange Management Act, administered by the Reserve Bank of India. The penalties can be up to three times the amount involved.

Mistake 19: Keeping a Resident Savings Account After Becoming an NRI

What it is: An individual moves abroad for employment in 2024. Their HDFC/SBI/ICICI savings account, salary account, and fixed deposits continue operating as resident accounts in 2025 and 2026.

Why it happens: Banks do not proactively track when a customer becomes an NRI. The obligation to inform the bank falls entirely on the account holder under FEMA regulations. Since the account continues to function normally (debit card works, UPI works, net banking works), there is no operational trigger to convert.

The cost: Operating a resident account as an NRI is a FEMA violation. Under Section 13 of FEMA, the penalty can be up to three times the sum involved, or Rs 2,00,000 where the amount is not quantifiable -- whichever is higher. Additionally, interest earned on a resident account as an NRI is not entitled to NRE tax-free treatment, meaning you lose the tax benefit you could have earned on an NRE FD. If the RBI or ED (Enforcement Directorate) investigates, the consequences include compounding fees and potential prosecution for persistent violations.

Quick Fix: Within a reasonable time of your residential status changing to NRI (the RBI expects this upon becoming an NRI), inform all your banks and request conversion of your accounts. Savings accounts become NRO accounts. Open an NRE account for fresh remittances from abroad.

Mistake 20: Not Converting Accounts and Maintaining Improper Account Structure

What it is: Beyond simply keeping the old account open (Mistake 19), the NRI fails to set up the proper NRE/NRO/FCNR account structure, leading to commingling of funds.

Why it happens: NRIs do not understand the difference between NRE (tax-free, fully repatriable), NRO (taxable, restricted repatriation), and FCNR (foreign currency, tax-free). They dump all funds into one account.

The cost: NRE accounts hold foreign earnings remitted to India -- the interest is tax-free and the principal is fully repatriable. NRO accounts hold Indian-sourced income (rent, dividends, interest) -- the interest is taxable and repatriation requires compliance certificates. Mixing the two in a single NRO account means: (a) you pay tax on interest that could have been tax-free in an NRE account, and (b) you create documentation nightmares for repatriation.

On NRE FDs of Rs 50,00,000 at 7%, the tax-free interest is Rs 3,50,000. If this money sits in an NRO account instead, TDS of Rs 1,09,200 is deducted, and even after refund, you have lost the time value and compliance cost.

Quick Fix: Maintain a clear three-account structure: NRE for foreign earnings, NRO for Indian income, and FCNR for foreign currency deposits (if you want to avoid exchange rate risk). Never transfer Indian-sourced income into NRE accounts. Maintain proper documentation for all transfers.

Mistake 21: Exceeding the Liberalized Remittance Scheme (LRS) Limit

What it is: The LRS limit for resident individuals is USD 250,000 per financial year. NRIs who are returning to India or who have family members remitting on their behalf exceed this limit without proper reporting.

Why it happens: LRS applies to resident individuals sending money out of India. Confusion arises when NRI family dynamics are involved -- an NRI asks their resident parent to remit funds, or an NRI returning to India makes multiple remittances in the transition year. The Rs 7,00,000 TCS threshold (Tax Collected at Source at 20% for remittances exceeding Rs 7,00,000 for non-specified purposes) adds another layer of complexity.

The cost: Remittances exceeding the LRS limit without RBI approval violate FEMA. Penalties under Section 13 of FEMA apply. Additionally, TCS at 20% on remittances above Rs 7,00,000 (for non-education, non-medical purposes) is a significant upfront cost, though it is adjustable against tax liability.

Quick Fix: Track all remittances by family members against the USD 250,000 annual limit. For amounts exceeding the limit, seek RBI approval through your authorized dealer bank. Ensure TCS is factored into your tax planning and claimed as credit when filing ITR.

Mistake 22: Repatriating Funds from NRO Without Form 15CA/15CB Compliance

What it is: An NRI transfers Rs 25,00,000 from their NRO account to their overseas bank account. The bank processes the transfer without the NRI submitting Form 15CA (online declaration) and Form 15CB (CA certificate).

Why it happens: Some banks are lax in enforcement. NRIs use alternative channels or older relationship-based banking that bypasses compliance checks. Some NRIs are genuinely unaware of the requirement.

The cost: Under Section 271-I, failure to furnish Form 15CA/15CB attracts a penalty of Rs 1,00,000 per transaction. The bank itself faces penalties, which may lead to freezing the NRI's account pending compliance. Additionally, the IT department tracks all foreign remittances -- a remittance without 15CA/15CB is flagged and can trigger a notice.

NRO repatriation is capped at USD 1,000,000 per financial year (after payment of applicable taxes). Form 15CB, signed by a CA, certifies that all taxes have been paid on the funds being repatriated.

Quick Fix: Before initiating any NRO repatriation, engage a CA to issue Form 15CB. File Form 15CA online on the income tax portal. Submit both to the bank along with the remittance request. Budget 7--10 working days for this process.

Mistake 23: Receiving Salary in an Indian Resident Account While Working Abroad

What it is: An NRI working in Dubai continues to receive a portion of their salary (or the full salary) in their old Indian resident savings account. They may also receive freelance payments or consulting fees in this account.

Why it happens: The NRI has EMIs, SIPs, and other commitments debiting from the Indian account. Routing salary through the Indian account seems convenient.

The cost: This is a multi-layered violation. First, the resident account should have been converted to NRO (FEMA violation). Second, salary for services rendered outside India is not taxable in India for an NRI -- but depositing it in an Indian account creates a presumption of Indian income, potentially triggering tax demands. Third, if the employer is an Indian company, they are required to deduct TDS on salary under Section 192, even if the NRI is not taxable on that salary in India (creating a withholding mess). Fourth, the salary deposited in a resident account cannot be freely repatriated like NRE funds.

Quick Fix: Receive your foreign salary in your overseas bank account. If you need funds in India, remit them to your NRE account (which is fully repatriable and earns tax-free interest). For Indian commitments (EMIs, SIPs), set up payments from your NRE or NRO account and fund them via inward remittance.

Part E: Investment and Global Reporting Failures (Mistakes 24--28)

These mistakes carry the harshest penalties because they involve violations of foreign reporting laws -- not just Indian rules. The IRS, HMRC, CRA, and IRAS have aggressive enforcement programs with penalties that can exceed the value of the unreported assets.

Mistake 24: US-Based NRI Not Filing FBAR (FinCEN 114)

What it is: A US-based NRI (green card holder or US tax resident) has Indian bank accounts, NRE FDs, NRO FDs, and demat accounts with an aggregate value exceeding USD 10,000 at any point during the calendar year. They do not file the FBAR (Report of Foreign Bank and Financial Accounts) with FinCEN.

Why it happens: NRIs focus on their Indian tax filing and US 1040 filing but overlook the separate FBAR filing requirement, which goes to FinCEN (Financial Crimes Enforcement Network), not the IRS. The FBAR is filed separately from the tax return, with a deadline of April 15 (auto-extended to October 15).

The cost: Non-willful FBAR penalties are up to USD 10,000 per account per year. Willful violations carry penalties of up to USD 100,000 or 50% of the account balance, whichever is greater, per violation. An NRI with 4 Indian accounts (savings, 2 FDs, demat) who fails to file for 3 years faces potential non-willful penalties of USD 120,000 (4 accounts x USD 10,000 x 3 years). Criminal prosecution is possible for willful violations.

This is not a theoretical risk. The IRS has collected billions in FBAR penalties through its enforcement programs.

Quick Fix: File FBAR annually by the deadline. Report every Indian financial account -- savings, FDs, PPF, demat, mutual fund folios, and any account where you have signatory authority (including joint accounts and accounts where you are a Power of Attorney holder). If you have missed past filings, consider the IRS Streamlined Filing Compliance Procedures to come into compliance with reduced penalties.

Mistake 25: Indian Mutual Funds Treated as PFICs Not Reported by US NRIs

What it is: Indian mutual funds are classified as Passive Foreign Investment Companies (PFICs) under US tax law. US-based NRIs holding Indian mutual funds must file Form 8621 for each PFIC and are subject to punitive taxation on gains and distributions.

Why it happens: NRIs started SIPs in Indian mutual funds before moving to the US and continue holding them. Indian CAs are not familiar with PFIC rules, and US CPAs may not know the NRI holds Indian mutual funds.

The cost: PFIC taxation is extraordinarily harsh. Gains are taxed at the highest ordinary income rate (37% for 2025--2026) plus an interest charge for the deferral period, regardless of how long the fund was held. There is no long-term capital gains rate for PFICs unless a QEF or Mark-to-Market election is made. On a Rs 20,00,000 (approximately USD 24,000) gain, the PFIC tax plus interest charge can easily exceed 50% of the gain.

Failure to file Form 8621 can result in the statute of limitations remaining open indefinitely on the NRI's entire US tax return for that year.

Quick Fix: If you are a US tax resident, avoid holding Indian mutual funds. Redeem existing holdings and invest through US-based mutual funds or ETFs instead. If you must hold Indian mutual funds, make a QEF or Mark-to-Market election and file Form 8621 annually. Coordinate between your Indian CA and US CPA to ensure both sides are aligned.

Mistake 26: Not Declaring Indian Investments in Country of Residence

What it is: Beyond the US FBAR/PFIC issue, NRIs in the UK (HMRC), Canada (CRA -- Form T1135 for specified foreign property exceeding CAD 100,000), Australia (ATO), and other countries fail to report their Indian assets and income in their country of residence.

Why it happens: NRIs compartmentalize their financial lives -- "India taxes are handled by my Indian CA, and UK taxes are handled by my UK accountant." Neither professional has full visibility into the other jurisdiction.

The cost: Penalties vary by country. In Canada, failure to file T1135 attracts a penalty of CAD 25 per day (up to CAD 2,500) for late filing, and CAD 500 per month (up to CAD 12,000) for each year of non-filing for a knowingly late return. In the UK, HMRC can impose penalties of 100--200% of the tax due on undeclared offshore income. In Australia, the ATO can impose penalties of 75% of the tax shortfall for intentional disregard.

Quick Fix: Provide your overseas tax advisor with a complete list of all Indian assets: bank accounts, fixed deposits, property, mutual funds, shares, PPF, NPS, and any other financial instruments. Ensure they report these in the appropriate foreign asset disclosure forms. The key principle is: as a tax resident of your country, you must report your worldwide income and worldwide assets, including everything in India.

Mistake 27: Mixing NRE and NRO Accounts for Investment Purposes

What it is: An NRI uses NRO funds (Indian-sourced income) to buy shares, mutual funds, or property, then attempts to repatriate the gains as if they were NRE funds (freely repatriable). Alternatively, they invest NRE funds into products that convert the NRE character to NRO, losing repatriability.

Why it happens: NRIs do not track the source of funds when making investments. The distinction between NRE and NRO feels bureaucratic and is easy to ignore in practice.

The cost: NRE funds invested in NRE-compatible instruments (NRE FDs, certain mutual fund schemes purchased via NRE funds) retain their repatriable character. NRO funds are subject to the USD 1,000,000 annual repatriation cap and require 15CA/15CB compliance. Mixing funds means: (a) you may lose the tax-free status of NRE interest/returns, (b) you create repatriation complications, and (c) you make it difficult to prove the source of funds for overseas tax reporting.

Quick Fix: Maintain a strict segregation. NRE funds should be invested through NRE-linked demat and mutual fund accounts. NRO funds should be invested through NRO-linked accounts. Never transfer NRO funds to NRE accounts (this is prohibited under FEMA except through the proper repatriation process). Keep clear records of which account funded which investment.

Mistake 28: Ignoring the GIFT City (IFSC) Zero-Tax Option

What it is: Gujarat International Finance Tec-City (GIFT City) in Gandhinagar operates as an International Financial Services Centre (IFSC) with significant tax incentives. NRIs can invest through GIFT City-registered fund managers and intermediaries, potentially accessing zero or reduced tax on certain investment income.

Why it happens: GIFT City is relatively new, and awareness among NRIs is low. Most NRI investment conversations revolve around traditional NRE/NRO routes. Financial advisors in India are not yet widely recommending GIFT City structures.

The cost: GIFT City IFSC offers: (a) zero tax on capital gains from specified securities for non-residents, (b) no STT (Securities Transaction Tax), (c) no CTT (Commodities Transaction Tax), (d) no stamp duty on securities transactions, and (e) GST exemptions on certain financial services. An NRI with an active portfolio generating Rs 10,00,000 in annual capital gains through traditional channels pays approximately Rs 1,25,000--1,50,000 in tax (12.5% LTCG) plus STT. Through a GIFT City route, significant portions of this can be eliminated.

Quick Fix: Explore GIFT City investment options through registered IFSC intermediaries. Several major Indian brokerages and fund houses now operate in GIFT City. Evaluate whether your investment size justifies the administrative setup. For portfolios above Rs 50,00,000, the tax savings can be substantial. Consult a CA familiar with IFSC regulations.

10 Frequently Asked Questions

1. I am an NRI with only NRO fixed deposit interest of Rs 1,80,000. Do I need to file an ITR?

While the income is below the basic exemption limit and no tax is due, TDS has likely been deducted at 30% plus cess. You should file ITR-2 to claim a full refund of the TDS deducted. Without filing, the refund is forfeited.

2. Can an NRI claim deductions under Section 80C, 80D, and other Chapter VI-A deductions?

Under the old regime, NRIs can claim most Section 80C deductions (life insurance premium, PPF contributions made when resident, ELSS, etc.) and Section 80D (health insurance for self and parents in India). Under the new regime, these deductions are not available. NRIs cannot claim certain deductions like Section 80G for donations and some others that are restricted to residents.

3. My Indian property was inherited. What is my cost of acquisition for capital gains?

The cost of acquisition is the cost at which the previous owner (the person from whom you inherited) acquired the property. If the property was acquired by the previous owner before April 1, 2001, you may adopt the fair market value as on April 1, 2001 as the cost. The holding period includes the previous owner's holding period.

4. I am a US NRI. Should I sell my Indian mutual funds?

Given the punitive PFIC taxation, most US-based tax advisors recommend liquidating Indian mutual fund holdings. Direct equity (Indian stocks) is generally not classified as PFIC and may be a better option for US NRIs wanting Indian market exposure. Alternatively, invest in US-listed ETFs that provide Indian market exposure. Consult both your Indian CA and US CPA before making any decision.

5. What is the TDS rate when an NRI sells property in India?

For long-term capital gains (property held over 24 months), TDS under Section 195 is 12.5% of the gross sale consideration (not just the gain) plus applicable surcharge and cess. For short-term capital gains, TDS is at 30% plus surcharge and cess. These rates can be reduced by obtaining a Section 197 lower TDS certificate based on the actual computed capital gain.

6. Can I transfer money from my NRO account to my NRE account?

Yes, but it is subject to conditions. The transfer is allowed up to USD 1,000,000 per financial year, subject to payment of applicable taxes. You must provide Form 15CA and 15CB to the bank. The bank verifies tax compliance before processing the transfer. This is essentially a repatriation transaction.

7. I have been an NRI for 10 years and never converted my resident savings account. What should I do?

Convert immediately. Approach your bank with your passport showing your departure and overseas visa/work permit. Request conversion of the savings account to NRO and open a new NRE account. For the past period of non-compliance, consider voluntary disclosure and regularization with FEMA counsel to avoid penalties.

8. Does the India-UAE DTAA provide any benefit on NRO interest for NRIs in the UAE?

The India-UAE DTAA (as amended) provides for taxation of interest in the country of residence or the country of source. The treaty provisions should be reviewed carefully. NRIs in UAE (which has no personal income tax) should evaluate whether the treaty provides a rate lower than the domestic 30%. In many cases, the domestic rate may still apply. Submit TRC and Form 10F to the bank regardless, and consult a CA for treaty-specific analysis.

9. What happens if I miss the advance tax deadline after selling property?

Interest under Section 234C is charged at 1% per month on the shortfall for each quarter. If you sell property in Q2 (July--September), the advance tax for that quarter is due by September 15. Missing it means interest accumulates from that date until the tax is paid. The interest is not waivable and is charged irrespective of whether you eventually pay the full tax when filing.

10. How does GIFT City benefit NRI investors?

GIFT City IFSC offers NRIs a tax-efficient investment platform. Key benefits include exemption from capital gains tax on specified securities, no STT, no stamp duty, and ability to invest in Indian securities without the traditional NRE/NRO routing. Several mutual funds, AIFs, and portfolio management services are now available through GIFT City intermediaries. This is particularly useful for NRIs with large portfolios seeking to optimize after-tax returns on Indian investments.
