Tax Filing for US NRIs in 2026 - The Complete Dual Country Guide

You filed your 1040 on time. Paid your US taxes. Thought you were done.

Then your friend mentioned FBAR. Your accountant asked about Form 8621. And suddenly that Indian mutual fund you bought three years ago feels like a ticking time bomb.

If this sounds familiar, you are not alone. At Belong, our community includes thousands of US-based NRIs navigating this exact maze.

The questions pour in every tax season. "Do I file in India too?" "What is PFIC and why is my CPA panicking?" "Can I just ignore my NRO account?"

Here is the problem. Most tax guides cover either US filing or India filing. Not both. And for US NRIs with Indian investments, you need to understand both systems and how they interact.

This guide puts everything in one place.

Every form. Every deadline. Every trap.

Specifically for US-based NRIs with financial ties to India in 2026.

No jargon without explanation.

No assumptions about what you already know. Just a clear map through the most complex tax situation any NRI faces.

Why US NRIs Have the Hardest Tax Situation

Let us be upfront. If you are an NRI in the UAE, your tax life is simple. The UAE has no income tax. India-UAE DTAA makes things clean.

US NRIs? Not so lucky.

The United States taxes its citizens, green card holders and tax residents on their worldwide income.

That includes your Indian salary, rental income, FD interest, mutual fund gains, and even the interest on your NRE account.

India also wants to tax your Indian-sourced income.

NRE FD interest? Tax-free in India. But taxable in the US. NRO FD interest? Taxed in India at 30% TDS.

And then the US wants its share too.

You are caught between two tax systems.

The India-US DTAA (Double Taxation Avoidance Agreement) helps prevent double taxation. But it does not eliminate complexity.

You still need to file in both countries, report foreign assets, and claim credits correctly.

One wrong move and you face penalties from the IRS, the Indian Income Tax Department, or both.

👉 Tip: The US-India DTAA allows you to claim Foreign Tax Credits on your US return for taxes paid in India. This prevents true double taxation on the same income. But you must actively claim it. It is not automatic.

Are You a "US Person"? Confirm Before Anything Else

Before diving into forms and deadlines, confirm your tax status.

The IRS definition of a "US person" is broader than most people realise.

You are a US person for tax purposes if you are:

A US citizen living anywhere in the world. Even if you live in India, the IRS still expects your worldwide income reported.

A Green Card holder. The moment you get your green card, worldwide reporting kicks in. It does not stop until you formally surrender the card through proper channels.

A tax resident under the Substantial Presence Test. This catches most H-1B and L-1 visa holders. Here is how it works.

Count all the days you were physically in the US during the current calendar year. Add one-third of the days from the prior year.

Add one-sixth of the days from two years ago. If the total exceeds 183, you are a US tax resident.

Example: Raj is on an H-1B visa. He was in the US for 300 days in 2026, 350 days in 2025 and 360 days in 2024. His count: 300 + (350/3) + (360/6) = 300 + 117 + 60 = 477. That exceeds 183. Raj is a US tax resident.

Separately, India determines your status under FEMA and the Income Tax Act.

If you spent fewer than 182 days in India during the financial year (April 1 to March 31), you are an NRI for Indian tax purposes.

You can be a US tax resident AND an Indian NRI at the same time. This is the dual-filing situation most US NRIs find themselves in.

Read more about NRI residential status and how it affects your investments.

👉 Tip: Keep a detailed log of your travel dates. Both the IRS and Indian tax authorities can ask for proof. Your passport stamps are your best evidence.

The 2026-2027 Tax Calendar: Every Deadline You Need

Tax filing for US NRIs involves two countries with different financial years.

India runs April to March. The US runs January to December.

Here is your complete calendar for income earned in 2026.

US Deadlines (for calendar year 2026, filed in 2027):

April 15, 2027: US tax return (Form 1040) due. Taxes must be paid by this date even if you file an extension. Interest accrues on unpaid amounts from this date.

April 15, 2027: FBAR (FinCEN Form 114) due.

Automatic extension to October 15, 2027 if you miss this date. No need to request an extension.

June 15, 2027: Automatic 2-month filing extension if you live outside the US on April 15. Interest still accrues from April 15.

October 15, 2027: Final extended deadline for 1040 (if you filed Form 4868 by April 15). Also the final FBAR deadline.

India Deadlines (for FY 2026-27, meaning April 2026 to March 2027):

July 31, 2027: Indian Income Tax Return due for NRIs without audit requirements. This is the standard deadline.

October 31, 2027: Extended deadline if you need a tax audit.

December 31, 2027: Belated return filing deadline if you missed July 31.

March 31, 2028: Last date to file updated return (with additional tax payment).

Key point: Income earned in India between January and March 2026 falls in India's FY 2025-26 (filed by July 31, 2026). Income from April to December 2026 falls in India's FY 2026-27 (filed by July 31, 2027).

But for US purposes, all of calendar year 2026 goes on one return filed by April 15, 2027.

This mismatch means you may need to file Indian returns for two different financial years to cover the same US tax year.

👉 Tip: Create a shared spreadsheet with columns for each income source, the India tax treatment, and the US tax treatment. Update it monthly. This single document will save hours during tax season.

Every Form a US NRI Needs to Know

This is the section that trips up almost everyone. There are at least 6-8 forms involved when you file in both countries.

Here is what each one does and when you need it.

US Forms (Filed with the IRS or FinCEN)

Form 1040: Your main US tax return.

Report all worldwide income here, including Indian salary, FD interest, rental income, capital gains from mutual funds or property sales in India.

Schedule B: Attached to Form 1040. Questions 7a and 7b ask if you have foreign accounts. If yes, you must indicate which country and confirm you filed FBAR.

Checking "No" when you have Indian accounts is a red flag the IRS catches through FATCA data exchange.

Form 8938 (FATCA): Statement of Specified Foreign Financial Assets.

Filed WITH your 1040. Required if your foreign financial assets exceed USD 50,000 on the last day of the year OR USD 75,000 at any point during the year (for single filers living in the US). Thresholds are higher for joint filers and those living abroad.

FinCEN Form 114 (FBAR): Report of Foreign Bank and Financial Accounts. Filed SEPARATELY through the BSA E-Filing System, NOT with your tax return.

Required if the aggregate value of all your foreign financial accounts exceeds USD 10,000 at any point during the calendar year.

Read our detailed FBAR filing guide for step-by-step instructions.

Form 8621: Information Return by a Shareholder of a PFIC. Required for each Indian mutual fund or ETF you hold.

Yes, each one separately. This is the form that makes Indian mutual funds a nightmare for US NRIs. More on this below.

Form 1116: Foreign Tax Credit. This is how you claim credit on your US return for taxes already paid in India. Without it, you get taxed twice.

Form 2555: Foreign Earned Income Exclusion. If you earned income while physically present in India, you may qualify to exclude up to USD 126,500 (2026 limit, inflation-adjusted) from US taxable income.

India Forms (Filed with the Income Tax Department)

ITR-2: The most common form for NRIs with income from salary, property, capital gains or foreign assets. NRIs cannot use ITR-1.

Form 67: Required to claim DTAA tax credits in India for taxes paid in the US. Must be filed before or along with your ITR.

Schedule FA: Foreign Assets schedule within your Indian return. Report your US bank accounts, brokerage accounts, and other foreign assets here.

Form 15CA/15CB: Required when repatriating money from India. Form 15CA is an online declaration. Form 15CB is a CA certificate required for payments above Rs. 5 lakh.

👉 Tip: FBAR and Form 8938 look similar but go to different agencies, have different thresholds and cover different assets. Many NRIs file one but miss the other. Check both requirements every year.

The PFIC Problem: Why Indian Mutual Funds Hurt US NRIs

This is the single most important section for US-based NRIs with Indian investments.

PFIC stands for Passive Foreign Investment Company. The IRS classifies most Indian mutual funds and ETFs as PFICs. This is not a bug in the system. It is by design.

The US tax code penalises investments in foreign pooled vehicles to encourage Americans to invest in US-domiciled funds.

What makes PFICs so painful:

Your gains are taxed at ordinary income rates (up to 37%), not the lower capital gains rate (15-20%) that applies to US mutual funds.

An additional interest charge is applied on "excess distributions" as if you should have been paying tax each year the fund grew.

You must file Form 8621 for EACH PFIC holding. If you have 5 Indian mutual funds, that is 5 separate Form 8621 filings. CPA fees for PFIC compliance alone can run USD 500-2,000 per fund.

What counts as a PFIC:

Indian mutual funds (equity, debt, hybrid, all categories). Indian ETFs listed on NSE or BSE. ULIPs with investment components. Even some Indian insurance products.

What does NOT count as a PFIC:

Direct Indian stocks (you own the shares, not units in a pooled fund). NRE and NRO fixed deposits. Real estate. PPF, EPF, NPS (though these have separate reporting requirements). Indian government bonds held directly.

The bottom line: If you are a US tax resident, investing in Indian mutual funds is almost never worth it after PFIC taxation and compliance costs.

Read more about PFIC implications in mutual fund investing mistakes and how GIFT City structures compare.

👉 Tip: If you moved to the US while holding Indian mutual funds, consider redeeming them. Yes, you will pay capital gains tax in India. But ongoing PFIC taxation plus annual Form 8621 compliance costs are almost always worse. Consult a cross-border tax advisor before acting.

Smart Investment Alternatives for US NRIs

So Indian mutual funds are out. What can you invest in?

US-domiciled India ETFs.

Funds like iShares MSCI India ETF (INDA) or WisdomTree India Earnings Fund (EPI) give you Indian market exposure without PFIC complications.

They are US funds, taxed under normal US rules.

Direct Indian stocks through PIS.

You buy the shares directly. No pooled fund structure. No PFIC. You pay Indian capital gains tax (12.5% LTCG, 20% STCG) and claim Foreign Tax Credits on your US return.

Budget 2026 doubled the individual NRI investment cap per company from 5% to 10% of paid-up capital (Source: Union Budget 2026).

NRE and FCNR Fixed Deposits.

Interest is tax-free in India. Taxable in the US as ordinary income. But no PFIC, no Form 8621, simple reporting. Compare rates on our NRI FD rates explorer.

GIFT City AIFs (with caution).

Some GIFT City AIFs structured as partnerships may avoid PFIC classification. But this requires careful structuring and expert tax advice. Category III AIFs investing in Indian equities are exempt from Indian capital gains tax under Section 10(4D).

But the US still taxes your worldwide income, so the Indian exemption only helps reduce the Foreign Tax Credit equation.

GIFT City FDs. USD-denominated fixed deposits in GIFT City are straightforward interest income on your 1040.

No PFIC. No complexity. Interest is exempt in India, taxable in the US at your ordinary rate. Check rates on our NRI FD rate tool.

Indian real estate. No PFIC. Rental income is taxable in both countries (claim FTC). Capital gains on sale are taxable in India (with TDS under Section 195) and reportable in the US. DTAA provisions apply.

Track Indian market movements via our GIFT Nifty tracker and explore GIFT City mutual funds (noting the PFIC caveat for US residents).

👉 Tip: If you are a US NRI and want to invest in India, the simplest approach is: NRE FDs for safety, direct stocks for growth, US-domiciled India ETFs for convenience. Avoid Indian mutual funds entirely.

How the India-US DTAA Prevents Double Taxation

The India-US DTAA is your shield against being taxed twice on the same income. But it requires active steps from you.

Here is how it works in practice.

Scenario 1: NRO FD Interest

India deducts 30% TDS on your NRO FD interest. You can claim this 30% as a Foreign Tax Credit on your US return (Form 1116).

If your US tax rate on that income is 24%, the credit covers it fully. You may even have excess credits to carry forward.

Scenario 2: Indian rental income

India taxes your rental income and deducts TDS. You report the same rental income on your US 1040. You claim the Indian tax paid as FTC.

The net effect: you pay the higher of the two tax rates, not both.

Scenario 3: Capital gains on Indian stocks

India charges 12.5% LTCG (above Rs. 1.25 lakh) or 20% STCG. The US also taxes these gains. You claim the Indian tax as FTC.

Since US capital gains rates (15-20% federal) are often comparable to Indian rates, your net additional US tax may be small or zero.

Scenario 4: NRE FD interest

Tax-free in India. Fully taxable in the US. No FTC to claim because no Indian tax was paid.

This catches many NRIs by surprise. They assume "tax-free" means tax-free everywhere.

To claim DTAA benefits in India, file Form 67 before or along with your Indian ITR. In the US, use Form 1116.

Read more about avoiding double taxation for NRIs and the India-specific DTAA framework (note: the India-US treaty differs from India-UAE).

👉 Tip: Keep every Indian tax payment receipt, TDS certificate (Form 16A), and challan. You need these to support your Foreign Tax Credit claims on the US return. The IRS can ask for documentation.

India's New Income Tax Act 2025: What Changed

India introduced a new Income Tax Act effective April 1, 2026, replacing the 1961 Act (Source: Income Tax Department).

For NRIs, the practical impact is mostly structural. Tax rates and NRI investment rules have not changed dramatically.

Key points relevant to US NRIs:

The new Act modernises language and structure. Section numbers have changed. Your CA or tax software will handle this. You do not need to learn new section numbers.

NRI investment rules remain largely the same under FEMA. The FEMA framework (not the Income Tax Act) governs what NRIs can and cannot invest in.

Budget 2026 doubled the individual NRI investment cap in listed companies from 5% to 10% of paid-up capital. The aggregate NRI cap was raised from 10% to 24% (Source: Union Budget 2026).

This is good news for US NRIs investing through direct stocks (the PIS route), as it gives you more room per company.

TDS rates on NRI income remain unchanged. 30% on NRO interest. 12.5% on LTCG above Rs. 1.25 lakh. 20% on STCG from equity.

The old vs new tax regime distinction still applies. Most NRIs benefit from the new regime (lower rates, fewer deductions).

FBAR vs Form 8938: The Confusion Explained

These two requirements look similar. They serve different purposes and go to different places.

Most US NRIs with Indian accounts need to file FBAR. Fewer need Form 8938 because its threshold is higher.

Critical detail: The FBAR threshold uses the MAXIMUM balance at any point during the year, not the year-end balance.

If your NRO account had Rs. 12 lakh in July (roughly USD 14,000) but only Rs. 5 lakh at year-end, you still exceeded the threshold.

Penalties after the 2023 Supreme Court ruling in Bittner v. United States apply per report, not per account. This was a significant win for taxpayers.

If you have been missing FBAR filings, the IRS offers amnesty programs.

The Streamlined Filing Compliance Procedures let you catch up without the harshest penalties if your non-compliance was non-willful. Read our complete FBAR guide for filing instructions.

👉 Tip: Indian banks report your account information to the IRS automatically under FATCA data exchange. The IRS already knows about your NRE and NRO accounts. Filing FBAR is not optional. It is the bare minimum.

Filing Your Indian Tax Return as a US NRI

Even if you are filing in the US, you may also need to file in India. Here is when.

You must file an Indian ITR if:

Your total Indian income exceeds Rs. 3 lakh (basic exemption under the new regime) in a financial year.

TDS was deducted on your Indian income and you want a refund.

You have capital gains from selling Indian property, stocks or mutual funds.

You earned rental income from Indian property.

You may not need to file if:

Your only Indian income is NRE FD interest (tax-free in India, no filing needed for this alone).

Your total Indian income is below Rs. 3 lakh and no TDS was deducted.

Even if not required, consider filing anyway. A clean filing record helps with future investments, property transactions and repatriation. Banks and CAs check your filing history when processing large transactions.

Use ITR-2 (not ITR-1). NRIs cannot use ITR-1.

Claim DTAA benefits using Form 67. This requires your US Tax Residency Certificate or a copy of your 1040 showing US taxes paid.

Read our guides on how to file income tax in India as an NRI and common tax filing mistakes NRIs make.

What If You Already Hold Indian Mutual Funds?

This is the most common crisis we see. An NRI moved to the US years ago. They still have SIPs running in Indian mutual funds. Nobody told them about PFIC.

Option 1: Redeem and restructure.

Sell your Indian mutual fund holdings. Pay Indian capital gains tax (12.5% LTCG or 20% STCG).

Report the gains on your US return and claim FTC. Reinvest in PFIC-free alternatives (US-domiciled India ETFs, direct Indian stocks, NRE FDs).

The one-time tax hit is painful. But it ends the ongoing PFIC headache.

Option 2: Make a QEF or MTM election.

Qualified Electing Fund (QEF) requires the fund to provide you with specific income data. Most Indian AMCs do not provide this.

Mark-to-Market (MTM) election requires the fund to trade on an IRS-recognised exchange. Indian exchanges (BSE, NSE) are generally not on that list. In practice, neither election works well for Indian mutual funds.

Option 3: Continue holding and file Form 8621 annually.

If you choose to keep the funds, file Form 8621 for each one every year. Pay the PFIC tax (ordinary income rates + interest charge). Be prepared for high CPA fees.

This is rarely the best option unless the fund's returns significantly outperform available US alternatives.

Option 4: Explore GIFT City alternatives.

Some GIFT City AIFs may be structured to avoid PFIC classification. But this is fund-specific and requires verification with a US tax advisor. Do not assume all GIFT City funds escape PFIC rules.

The Tata India Dynamic Equity Fund, DSP Global Equity Fund and Edelweiss Greater China Equity Fund are GIFT City funds available through Belong, but US NRIs should verify PFIC status before investing.

The Sundaram India Mid Cap Fund at GIFT City is another option to explore, again with professional PFIC verification.

👉 Tip: If you are planning to move to the US and currently hold Indian mutual funds, redeem them BEFORE obtaining US tax residency (green card or 183+ days). Once you become a US person, the PFIC rules begin.

Repatriation: Getting Money from India to the US

Moving investment proceeds from India to your US bank involves both tax compliance and banking paperwork.

From NRE accounts: Fully repatriable. No limit. No Form 15CA/15CB needed for amounts up to Rs. 5 lakh per transaction. Above Rs. 5 lakh, you need Form 15CA (online) and Form 15CB (CA certificate).

From NRO accounts: Repatriable up to USD 1 million per financial year (net of taxes). Requires Form 15CA/15CB. The bank may also ask for tax clearance documentation.

From GIFT City accounts: Fully repatriable in foreign currency. No rupee conversion. No Form 15CA/15CB. This is one of the cleanest repatriation paths available to NRIs. Learn more about repatriation rules.

From property sale: After paying TDS (Section 195), the remaining amount can be repatriated through NRO. The CA certificate (15CB) confirms taxes have been paid. Processing can take 2-4 weeks.

On the US side, report the repatriated amount as part of your worldwide income (if it includes gains that have not yet been reported). If it is a return of principal, no additional US tax applies. Keep documentation showing the source of funds.

👉 Tip: Plan large repatriations toward the end of the Indian financial year (February-March). This gives you time to complete 15CA/15CB paperwork and ensures the amount falls within one year's USD 1 million NRO limit.

7 Mistakes US NRIs Make Every Tax Season

After working with hundreds of US-based NRIs, we see these same errors repeat every year.

Mistake 1: Not filing FBAR.

Many NRIs file their 1040 but skip FBAR entirely because their CPA did not mention it. FBAR is separate from your tax return. It goes to FinCEN, not the IRS. Penalties start at USD 16,536 per missed report.

Mistake 2: Ignoring PFIC on Indian mutual funds.

Holding Indian mutual funds without filing Form 8621 is a compliance violation. The IRS receives data from Indian financial institutions through FATCA. They know what you hold.

Mistake 3: Forgetting to report NRE FD interest on the US return.

NRE interest is tax-free in India. Not in the US. It must appear on your 1040 as interest income. Omitting it is underreporting income.

Mistake 4: Not claiming Foreign Tax Credits.

If India deducted TDS on your NRO interest, capital gains or rental income, you can claim those taxes as credits on your US return (Form 1116). Skipping this means you pay tax twice.

Mistake 5: Using year-end balances for FBAR instead of maximum balances.

FBAR uses the highest balance at any point during the year, not December 31 values. If your NRO account spiked in July when you received rental income, that higher amount is what matters.

Mistake 6: Operating a resident savings account after becoming NRI.

Under FEMA, you must convert your Indian resident savings account to NRO or NRE within a reasonable time of becoming an NRI. Operating a resident account as an NRI is a FEMA violation. Read about NRE vs NRO differences.

Mistake 7: Not filing Indian returns when TDS was deducted.

If India deducted TDS on your FD interest or capital gains, you may be entitled to a refund. You only get it by filing an Indian ITR. Not filing means you lose money.

Compliance Calendar: Month-by-Month Action Plan

Here is a practical calendar for US NRIs managing dual-country tax obligations.

January: Gather Indian bank statements, FD certificates and mutual fund statements for the calendar year just ended. Note the maximum balance in each account for FBAR purposes.

February-March: Collect Form 16A (TDS certificates) from Indian banks and AMCs. Collect your W-2, 1099s and other US income documents.

April 1-15: File or extend your US tax return (Form 1040). Pay estimated taxes owed. File FBAR if ready. If not, the automatic extension gives you until October 15.

April-June: Work with your CPA on Form 8938, Form 8621 (for any PFIC holdings) and Form 1116 (FTC). Complete FBAR if not done in April.

July 31: Deadline for Indian ITR filing (for FY ending March 31). File ITR-2 with Form 67 for DTAA credits.

September-October: Final review before FBAR and extended 1040 deadlines. Ensure three-way consistency between FBAR, Schedule B and Form 8938.

November-December: Review your Indian investment portfolio. Decide if any restructuring is needed before the next calendar year starts. This is the best time to exit PFIC holdings if you plan to do so.

👉 Tip: Find a CPA who specialises in US-India cross-border taxation. General CPAs often miss FBAR, PFIC and FEMA issues. The extra cost of a specialist (typically USD 1,500-3,000 for a complete dual-country filing) is far less than the penalty risk.

When You Return to India: Tax Transition Planning

If you are considering returning to India, start planning at least 12-18 months before the move.

Before leaving the US:

Redeem any Indian mutual funds (exit PFIC positions while you can still file US returns). Maximise contributions to 401(k) and IRA (these continue to grow tax-deferred).

Gather all US tax documents for the final partial-year return.

After arriving in India:

You become Resident but Not Ordinarily Resident (RNOR) for up to 2-3 years. During RNOR, your foreign income (US salary, 401k distributions, US rental income) is NOT taxed in India.

Convert NRE accounts to resident accounts. NRE FDs continue at the same rate until maturity. Convert or close your NRO account or retain it as a regular resident account.

Update your status with every AMC, bank and broker in India. Failure to update creates FEMA violations.

If you surrender your Green Card, you must file a final US return. There may be an "exit tax" if your net worth exceeds USD 2 million or average annual net income tax exceeded USD 190,000 (2026 threshold, inflation-adjusted).

Read the comprehensive returning NRI financial checklist and our guide on RNOR status benefits.

The Bottom Line: Compliance Is Not Optional

Filing taxes as a US NRI is complex. There is no sugarcoating it.

You deal with two tax systems, multiple forms, overlapping deadlines and investment structures that interact in non-obvious ways.

But it is manageable. Thousands of US NRIs do it every year. The ones who do it well follow a system: they keep records throughout the year, work with cross-border specialists and structure their investments to avoid unnecessary complexity (meaning no Indian mutual funds).

The ones who struggle are those who ignore the requirements until a penalty notice arrives.

By then, the cost of catching up is far higher than the cost of staying compliant.

Many NRIs in our community share their filing experiences, CPA recommendations and compliance tips every tax season.
