NRI US Tax Filing
Complete Guide 2025

Who Must File US Taxes?

The US taxes individuals based on either citizenship/residency or source of income. If you fall into any of the following categories, you have a US tax filing obligation:

• US citizens and Green Card holders — taxed on worldwide income regardless of where they live.
• Resident aliens — individuals who pass the Substantial Presence Test (SPT) are taxed on worldwide income, just like US citizens. Most H-1B, L-1, and O-1 visa holders fall into this category.
• Non-resident aliens with US-source income — taxed only on income effectively connected with a US trade or business, plus certain fixed/determinable income (interest, dividends, rents).
• Dual-status aliens — individuals who change status during the year (e.g., arriving on H-1B mid-year) may need to file as both non-resident and resident for different parts of the year.

Determining Your Tax Residency Status

Your residency status determines what you pay tax on and which form you file. The IRS uses two tests:

1. Green Card Test

If you are a lawful permanent resident (Green Card holder) at any time during the calendar year, you are a resident alien for the entire year. You file Form 1040 and report worldwide income.

2. Substantial Presence Test (SPT)

You are a resident alien if you were physically present in the US for at least 31 days during the current year AND a total of 183 days during the current year and the two preceding years, calculated as:

• All days present in the current year, plus
• 1/3 of the days present in the first preceding year, plus
• 1/6 of the days present in the second preceding year.

Types of Taxable Income for NRIs

As a resident alien, you must report all worldwide income to the IRS. As a non-resident alien, only US-source income is taxable. Here are the most common income types NRIs encounter:

Employment Income

Wages reported on Form W-2 are the primary income source for most NRIs on work visas. This includes salary, bonuses, RSUs (Restricted Stock Units), and ESOP exercises. RSU income is reported as ordinary income on the W-2 at vesting, and any subsequent gain or loss on selling those shares is a capital gain or loss.

Investment Income

Interest, dividends, and capital gains from US brokerage accounts are reported on Forms 1099-INT, 1099-DIV, and 1099-B. Resident aliens must also report income from Indian investments — including NRE/NRO account interest, Indian mutual fund dividends, and gains from Indian stock sales.

Rental Income

Income from rental property in India must be reported on Schedule E of your US return. You can deduct property taxes, maintenance, insurance, and depreciation. Indian TDS (Tax Deducted at Source) on rental income qualifies for a Foreign Tax Credit on your US return. See our detailed guide on US Tax on Indian Rental Income.

Self-Employment & Business Income

Freelance income, consulting fees, and business profits are reported on Schedule C. Self-employment tax (15.3% covering Social Security and Medicare) applies in addition to income tax. Use our Self-Employment Tax Calculator to estimate your liability.

Indian Mutual Funds (PFIC)

This is one of the most complex areas for NRIs. Indian mutual funds, ETFs, and ULIPs are classified as Passive Foreign Investment Companies (PFICs) under IRC Section 1291. PFICs face punitive default taxation — gains are spread over the holding period, taxed at the highest ordinary rate (37%), and hit with an interest charge. NRIs holding Indian mutual funds must file Form 8621 for each PFIC annually. The two alternatives — QEF election and Mark-to-Market — may reduce the burden but require careful analysis.

Key Forms & Schedules

NRI tax returns often involve more forms than a typical domestic return. Here is a reference of the most commonly needed forms:

FBAR & FATCA Reporting

FBAR and FATCA are two separate reporting requirements for foreign financial accounts. Many NRIs must file both.

FBAR (FinCEN Form 114)

You must file an FBAR if the aggregate value of all your foreign financial accounts exceeds $10,000 at any point during the calendar year. This includes:

• Bank accounts (savings, current, NRE, NRO)
• Fixed deposits and recurring deposits
• PPF (Public Provident Fund) and EPF accounts
• Demat accounts holding stocks
• Mutual fund accounts (even if classified as PFICs)
• Insurance policies with cash value (LIC, ULIPs)

FBAR is filed electronically through the BSA E-Filing System — it is not part of your tax return. The deadline is April 15 with an automatic extension to October 15. Penalties for non-filing are severe: up to $16,117 per account per year for non-willful violations (2025 inflation-adjusted) and $161,174 or 50% of the account balance for willful violations.

FATCA (Form 8938)

FATCA requires reporting of specified foreign financial assets on Form 8938, which is filed with your tax return. The thresholds are higher than FBAR:

DTAA: US-India Tax Treaty Benefits

The Double Taxation Avoidance Agreement (DTAA) between the US and India is one of the most powerful tools available to NRIs. It prevents the same income from being taxed in both countries and provides specific benefits:

Key Treaty Provisions

• Article 10 — Dividends: Withholding limited to 25% (15% for at least 10% corporate ownership).
• Article 11 — Interest: Withholding limited to 15% (10% for bank interest).
• Article 13 — Capital Gains: Gains from property may be taxed in the country where the property is situated, with FTC available in the other country.
• Article 20 — Teachers & Researchers: Income exempt from US tax for up to 2 years if the individual came from India to teach or conduct research at a university or recognized institution.
• Article 21 — Students: Payments from abroad for maintenance and education are exempt. Indian students on F-1/J-1 visas may also qualify for a standard deduction benefit.
• Article 25 — Relief from Double Taxation: The US allows a Foreign Tax Credit (Form 1116) for income taxes paid to India, and vice versa.

How to Claim Treaty Benefits

To claim a treaty-based position on your US return, you must file Form 8833 (Treaty-Based Return Position Disclosure) and clearly identify which article you are relying on. For reduced withholding, your employer or payer may require a Form W-8BEN or W-8BEN-E.

The most commonly used benefit is the Foreign Tax Credit (Form 1116), which allows you to offset US tax on income that was already taxed in India. This effectively eliminates double taxation on items like Indian rental income, capital gains, and NRO account interest.

Deductions & Credits for NRIs

Standard Deduction vs. Itemized

For tax year 2025, the standard deduction is $14,600 (single), $29,200 (married filing jointly), and $21,900 (head of household). Resident aliens can claim either standard or itemized — whichever is higher. Non-resident aliens on Form 1040-NR generally cannot claim the standard deduction, though Indian nationals may qualify under the DTAA Article 21 provision.

Common Deductions

• State and local taxes (SALT) — up to $10,000 per year for property and income/sales taxes.
• Mortgage interest — on up to $750,000 of acquisition debt (primary and secondary residence).
• Charitable contributions — to qualified US organizations (Indian charities generally do not qualify).
• Student loan interest — up to $2,500 for qualifying education loans (income phase-outs apply).
• Health Savings Account (HSA) — $4,150 (self) or $8,300 (family) for 2025.
• IRA contributions — up to $7,000 ($8,000 if 50+) for traditional IRA deductions (income limits apply).

Key Credits

• Foreign Tax Credit (Form 1116) — the single most important credit for NRIs. Offsets US tax dollar-for-dollar for taxes paid to India.
• Child Tax Credit — up to $2,000 per qualifying child under 17 (partially refundable). Children must have SSNs.
• Child and Dependent Care Credit — for daycare/childcare expenses while you work.
• Education Credits — American Opportunity Credit (up to $2,500/year for first 4 years) and Lifetime Learning Credit (up to $2,000/year).
• Earned Income Tax Credit — available to resident aliens with earned income below specified thresholds (not available to non-resident aliens).

State Tax Filing for NRIs

In addition to federal taxes, most states impose their own income tax. Nine states have no income tax: Alaska, Florida, Nevada, New Hampshire (no tax on wages), South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live in any other state, you likely need to file a state return.

State Residency Rules

Each state has its own definition of tax residency, which may differ from federal rules. Common triggers include maintaining a permanent home, spending more than 183 days in the state, or having a domicile there. California is particularly aggressive — it considers you a resident if you are in the state for any purpose other than temporary or transitory, and it has a "safe harbor" of only 9 months.

Multi-State Filing

If you moved between states during the year (common when relocating for a job), you may need to file part-year resident returns in both states. Some states also require non-resident returns if you earned income from sources in that state. States like New York apply "convenience of the employer" rules, taxing telecommuters even if they work remotely from another state.

Estimated Tax Payments

The US tax system is a pay-as-you-go system. If your employer withholds taxes from your paycheck (W-2), you are usually covered. But if you have significant income without withholding — such as rental income, self-employment income, or investment income — you may need to make quarterly estimated tax payments.

You are required to make estimated payments if you expect to owe $1,000 or more in taxes after subtracting withholding and credits. Safe harbor rules allow you to avoid penalties by paying either 90% of the current year's tax or 100% of the prior year's tax (110% if AGI exceeds $150,000).
