Most NRI tax problems do not begin at filing time. They begin nine to twelve months earlier, when a decision — a property sale, an account redesignation, an India visit that crossed an unexpected day count, a job change that triggered a new state nexus — was made without considering the tax consequences. By the time the W-2 lands in January and the ITR window opens in May, the consequences are already baked in. What filing season actually does is surface decisions that were already made. A clear calendar, an honest understanding of residency status and a small checklist of recurring mistakes can keep most NRI households out of the worst trouble.
The two-country calendar
The first thing every NRI tax filing season requires is a clear view of two simultaneous tax calendars — the US (calendar-year basis) and India (fiscal year 1 April to 31 March). The deadlines that matter most:
United States. The standard filing deadline is 15 April for the previous calendar year's return (Form 1040 for residents and resident aliens; Form 1040-NR for non-resident aliens). US citizens and resident aliens living abroad get an automatic two-month extension to 15 June without filing any form, though interest still accrues from 15 April. A further extension to 15 October is available by filing Form 4868 by the original deadline. FBAR (FinCEN Form 114) is due 15 April with an automatic extension to 15 October — no separate request needed.
India. The standard individual ITR deadline is 31 July for the previous financial year (so 31 July 2026 for FY 2025-26 filings). Audit cases extend to 31 October, and revised returns can be filed up to 31 December. Belated returns carry penalties and forfeit some loss-carryforward benefits, so the 31 July date is the one to treat as binding.
The structural challenge for NRIs is that these two calendars run on different fiscal years. Income earned January-March 2026 falls in two different tax years — calendar 2026 for the US and FY 2025-26 for India. Reconciling them requires careful timing of any income or asset moves that straddle the year boundaries.
Residency status: ROR, RNOR, NR
Indian residency for tax purposes is determined by the days-of-presence test. An individual is treated as a resident if they spend 182 days or more in India during the financial year, or 60 days in the year plus 365 days across the four preceding years. The 60-day threshold is extended to 182 days for Indian citizens leaving India for employment outside or for NRIs visiting India — which is the rule most NRIs rely on to remain non-resident during India visits.
For high-income earners, the 2020 Finance Act introduced a 120-day rule: if an Indian citizen or person of Indian origin earns more than INR 15 lakhs from Indian sources, the 60-day threshold tightens to 120 days. This catches a small but meaningful slice of NRIs who have significant Indian income (rental, dividend, capital gains) and who routinely visit India for extended periods.
The RNOR (Resident but Not Ordinarily Resident) status is the underused middle ground. An individual qualifies as RNOR if they meet the resident test but have been non-resident in nine of the ten preceding financial years, or have spent less than 729 days in India across the seven preceding years. RNOR status preserves the non-resident treatment for foreign income — only India-source income is taxed — while letting the individual technically be a resident. For returning NRIs, planning the timing of return to maximise the RNOR window can save substantial tax over the first two to three years back.
Foreign tax credit and DTAA
The India-US Double Taxation Avoidance Agreement (DTAA) operates on the credit method, not the exemption method. Income taxed in one country produces a credit in the other, capped at the tax that would have been due in the country granting the credit. This produces the correct overall outcome — income is taxed once, at the higher of the two countries' rates — but the mechanics require careful filing.
On the US side, Form 1116 claims the foreign tax credit for taxes paid to India. On the India side, Form 67 must be filed before the ITR to claim credit for US taxes paid. The Form 67 deadline (same as ITR) is the surface most NRIs trip on — the credit is forfeited if Form 67 isn't filed before the ITR is submitted.
The credit-method approach also affects timing. Tax paid in one country needs to match the income year it relates to in the other country. A US tax payment made in April 2026 for calendar 2025 income shows up in a different India fiscal year (most of it relates to FY 2024-25 and FY 2025-26 income). The accounting is straightforward if done carefully and produces wrong results if rushed.
FBAR and Form 8938: the offshore reporting
FBAR (FinCEN 114) is required for any US person with combined foreign financial accounts exceeding USD 10,000 at any point during the calendar year. The threshold is aggregate across all foreign accounts, not per-account. An NRO account, an NRE term deposit, an Indian demat, and a small foreign savings account each below USD 10,000 individually but summing to USD 10,500 collectively still triggers FBAR.
Form 8938 (Statement of Specified Foreign Financial Assets) reports under FATCA with higher and filing-status-dependent thresholds — USD 50,000 (single, US-resident, end-of-year) up to USD 600,000 (married joint, abroad, end-of-year). Form 8938 is filed with the tax return; FBAR is filed separately to FinCEN.
The penalty regimes for both are severe. FBAR willful-violation penalties can reach 50 percent of account balance per violation; non-willful penalties run up to USD 10,000 per violation. Form 8938 carries a USD 10,000 initial penalty with additional penalties for continued non-compliance. The Streamlined Filing Compliance Procedures offer a path for taxpayers who have missed FBAR or Form 8938 filings in past years without willful intent — worth investigating before deciding to begin filing current-year only.
India side: Schedule FA and foreign asset disclosure
NRIs filing in India who hold any foreign assets — bank accounts, brokerage accounts, real estate, business interests — must disclose them on Schedule FA of the ITR. The disclosure is required even when no income flows from the asset. The penalty for non-disclosure is INR 10 lakhs under the Black Money Act, which is a meaningful deterrent and explains why competent India CAs are increasingly insistent that NRI clients complete Schedule FA in full.
The challenge is that Schedule FA asks for asset values at specific points in time, in INR, with conversion rates that the taxpayer is expected to derive accurately. Maintaining a year-end statement for every foreign account, with INR equivalents at the appropriate exchange rates, is the discipline that makes Schedule FA filing routine rather than scrambling.
The five mistakes that cost the most
One — missing Form 67 in India. The foreign tax credit on the India side is forfeited if Form 67 isn't filed before the ITR. Many NRIs file the ITR claiming the credit and then file Form 67 a few weeks later. The credit is gone. The fix is to file Form 67 first, confirm acceptance, then file the ITR.
Two — misclassifying an NRO account as resident. Continuing to operate a previously-resident savings account after becoming NRI is a FEMA violation. The interest is taxed at resident rates while income tax filings show non-resident status, producing a mismatch the assessment can catch. The fix is to redesignate the account as NRO at the bank within the first six months of becoming NRI.
Three — not filing FBAR for a year when account balance briefly crossed USD 10,000. FBAR's threshold is "any time during the year," not "at year-end." A balance that touched USD 10,500 for two days during the year still triggers the filing. Many NRIs file based on year-end balance and miss intra-year peaks.
Four — ignoring Schedule FA because no income flowed. Disclosure is required regardless of income. A dormant US 401(k) for an NRI now resident in India must still be disclosed on Schedule FA. The penalty for non-disclosure under the Black Money Act is the same whether the account produced income or not.
Five — selling Indian property without planning the capital gains. Long-term capital gains on Indian property held by an NRI are taxed at 20 percent (with indexation), with TDS at 20 percent on the gross sale value. The TDS is significant — it can be 20 percent of a large round number while the actual tax due is a much smaller percent of the actual gain. A lower TDS certificate from the Assessing Officer (Form 13) issued before sale brings the TDS in line with the actual tax due. Without it, the seller is essentially extending an interest-free loan to the government and waiting for a refund the following year.
A practical 2026 checklist
- Confirm residency status for both countries based on actual days of presence.
- Aggregate foreign accounts to test the USD 10,000 FBAR threshold across the year, not just year-end.
- Compile year-end account statements with INR equivalents for Schedule FA.
- File India Form 67 before the ITR if claiming foreign tax credit.
- Confirm the W-2 / 1099 income matches the US tax return that will be filed.
- If selling Indian property, obtain the lower TDS certificate before the sale closes.
- If any prior-year FBAR or Form 8938 filings were missed, investigate the Streamlined Filing Compliance Procedures rather than starting fresh.
- Schedule a thirty-minute call with both the US CPA and the India CA in the same week so the credit-method timing matches across both filings.
FAQs
What is the US tax filing deadline for NRIs in 2026? 15 April for the previous calendar year's Form 1040 or 1040-NR. US citizens and resident aliens abroad get an automatic two-month extension to 15 June (interest accrues from 15 April), and Form 4868 extends to 15 October.
What is the India ITR deadline for NRIs in 2026? 31 July 2026 for individuals for FY 2025-26. Audit cases extend to 31 October.
Do NRIs need to file an India ITR every year? Only if total India-source income exceeds the basic exemption, or if Indian tax was withheld and a refund is due, or if any specified high-value transaction occurred. Many NRIs without Indian income do not file. Schedule FA disclosure obligations apply only when the NRI is a tax resident.
What is RNOR and when does it apply? Resident but Not Ordinarily Resident — qualifies if non-resident in nine of ten preceding years or less than 729 days in India across seven preceding years. Foreign income remains untaxed in India during the RNOR window. For returning NRIs, this typically covers the first two to three years back.
How does DTAA work between India and US? The credit method — income is taxed in the country of source, then a credit is allowed in the country of residence up to the tax that would have been due there. The net effect is that income is taxed once at the higher rate.
Is FBAR required for an NRE account? Yes. NRE accounts at Indian banks are foreign accounts for FBAR purposes, regardless of how the NRI categorises them internally.
Can I claim Indian foreign tax credit on US 1099 income? Form 1116 on the US return claims credit for taxes paid to India. The credit is capped at the US tax that would have been due on the same income. Excess foreign tax credit can carry forward for ten years.
What happens if I miss the Form 67 deadline? The foreign tax credit is forfeited for that year. The deadline is before the ITR is filed, not after.
The right cadence
The NRI households that handle this well share a small set of habits. They keep year-end statements for every foreign account in one folder. They run a single combined calendar that shows both countries' deadlines. They have a CPA in the US and a CA in India who talk to each other once a year before either of them files. They make any decision likely to have tax consequences — property sale, account redesignation, residency change — with a quick consultation before the action, not after. None of this is glamorous, and all of it pays for itself over a decade. The filing season is the surface; the planning under it is what actually determines the outcome.
