TL;DR (Summary): Every US citizen, Green Card holder, and resident alien is legally required to report worldwide income to the IRS regardless of where the income was earned or whether it was taxed abroad. Foreign income is reported on Form 1040 in the same manner as domestic income. In addition to the tax return itself, US persons with aggregate foreign financial account balances exceeding $10,000 must file an FBAR (FinCEN Form 114), and those with specified foreign financial assets exceeding $50,000 must file FATCA Form 8938. The Foreign Tax Credit (Form 1116) and the Foreign Earned Income Exclusion (Form 2555) are the two principal mechanisms for avoiding double taxation. Penalties for non-compliance can be severe up to $10,000 per non-willful FBAR violation and substantially more for willful violations. Professional guidance is strongly advisable for NRIs with complex cross-border income profiles.
The Worldwide Income Rule: Why the US Taxes Foreign Income
The United States applies a citizenship-based taxation model one of only two countries in the world (alongside Eritrea) to do so. Under this system, every US citizen and Green Card holder is subject to US federal income tax on their worldwide income, irrespective of where they reside or where the income originates. A US citizen living and working in Germany pays German income tax on their German salary, and also owes US federal tax on that same salary subject to relief mechanisms. A Green Card holder employed in India owes US tax on their Indian wages. An NRI who has become a US permanent resident owes US tax on interest earned in their NRE account in India.
This extraterritorial reach of US taxation surprises many immigrants and expatriates who assume that earning or living outside the US extinguishes their US tax obligations. It does not. The IRS enforces worldwide income reporting through a combination of treaty information exchange, FATCA reporting by foreign financial institutions, and the mandatory disclosure requirements that US persons themselves must file annually. Understanding the system and its available relief mechanisms is essential for anyone with income from outside the United States.
What Counts as Foreign Income?
Foreign income encompasses every form of income earned, received, or accruing outside the United States. This includes wages and salary from a foreign employer; self-employment income from services rendered outside the US; rental income from foreign real estate; interest earned on foreign bank accounts including NRE, NRO, and FCNR deposits in India; dividends from foreign stocks and equity mutual funds; capital gains from selling foreign property, stocks, or other assets; pension distributions from foreign retirement plans; business income from foreign partnerships, sole proprietorships, or companies; and passive income from foreign trusts and estates.
Income that is exempt from Indian tax most notably NRE and FCNR deposit interest is nevertheless taxable in the US under the worldwide income principle. The Indian statutory exemption only extinguishes Indian tax liability; it has no effect on the US tax obligation of a US person holding those accounts. This point is consistently misunderstood by Indian-Americans who assume that NRE account interest is "tax-free" globally it is tax-free in India only.
How to Report Foreign Income on Form 1040
Foreign income is reported on the same Form 1040 used for domestic income, on the same lines and schedules that correspond to the income type. Foreign wages and salary are reported on Line 1 of Form 1040. Foreign interest income is reported on Schedule B, Part I. Foreign dividend income is reported on Schedule B, Part II. Foreign rental income is reported on Schedule E. Foreign capital gains are reported on Schedule D. Foreign self-employment income is reported on Schedule C and Schedule SE.
All foreign income amounts must be converted from the foreign currency to US dollars using the exchange rate applicable at the time each payment was received. The IRS accepts the use of annual average exchange rates published by the Treasury Department for income received throughout the year, rather than requiring the precise exchange rate for every individual payment. For large, discrete transactions such as the sale of foreign property the exchange rate on the date of the specific transaction should be used.
The Foreign Tax Credit (Form 1116): Avoiding Double Taxation
The Foreign Tax Credit (FTC), claimed on IRS Form 1116, is the primary mechanism by which the US tax system prevents full double taxation of foreign income. It allows a dollar-for-dollar reduction in US federal tax liability for foreign taxes paid or accrued on the same income. For example, if an NRI earns India-sourced rental income and pays Indian income tax of $800 on it, they can claim a $800 credit against their US federal tax liability for the same income effectively paying only the higher of the two rates, not the sum of both.
Key rules governing the FTC include: the credit is limited to the amount of US federal tax attributable to the foreign income; unused credits can be carried back one year and forward ten years; and the credit applies to foreign income taxes paid in lieu of income taxes as well. For most NRIs earning India-sourced income subject to Indian TDS, the combination of the India-US DTAA and the Foreign Tax Credit effectively prevents economic double taxation, though the mechanics are complex and require careful calculation.
The Foreign Earned Income Exclusion (Form 2555)
The Foreign Earned Income Exclusion (FEIE), claimed on IRS Form 2555, allows qualifying US citizens and resident aliens who live and work outside the US to exclude a portion of their foreign-earned income from US federal income tax. For the 2024 tax year, the exclusion amount is $126,500 per person. To qualify, the taxpayer must have foreign earned income, have a tax home in a foreign country, and meet either the Bona Fide Residence Test or the Physical Presence Test (spending at least 330 full days in foreign countries during any 12-month period).
The FEIE applies only to earned income wages, salary, and net self-employment income from services performed outside the US. It does not apply to investment income, rental income, pension income, or other passive income. A critical limitation is that income excluded under the FEIE cannot be used as a basis for claiming the Foreign Tax Credit — you cannot exclude income and simultaneously claim a credit for foreign taxes paid on the same income.
FBAR: Reporting Foreign Bank Accounts (FinCEN Form 114)
The Foreign Bank Account Report FBAR is a mandatory annual disclosure filed with FinCEN (a bureau of the US Treasury) using FinCEN Form 114. Every US person who has a financial interest in, or signature authority over, one or more foreign financial accounts must file an FBAR if the aggregate maximum value of all such accounts exceeded $10,000 at any point during the calendar year. Foreign financial accounts include foreign bank accounts, foreign brokerage accounts, foreign mutual fund accounts, foreign pension accounts, and foreign insurance contracts with cash value.
The FBAR is filed electronically through FinCEN's BSA E-Filing System and is due by April 15 each year, with an automatic extension to October 15. For NRIs in the US, FBAR-reportable accounts commonly include NRE accounts, NRO accounts, FCNR deposits, Indian savings accounts, Demat accounts, and Indian mutual fund folios. The $10,000 threshold is an aggregate test across all accounts an NRI with three accounts each holding less than $10,000 but collectively exceeding $10,000 must file an FBAR reporting all three.
FATCA: Reporting Foreign Financial Assets (Form 8938)
The Foreign Account Tax Compliance Act (FATCA) imposes a separate asset-reporting requirement through IRS Form 8938, which is attached to the annual federal tax return. Form 8938 requires disclosure of specified foreign financial assets with aggregate values exceeding specified thresholds. For US-based single filers, the threshold is $50,000 at year-end or $75,000 at any point during the year. For married filing jointly, the thresholds are $100,000 and $150,000 respectively.
The FATCA Form 8938 requirement is in addition to not a substitute for the FBAR filing on FinCEN Form 114. Both are mandatory if the respective thresholds are met, and the two forms have different account coverage rules. Filing both where both are required is the only compliant approach.
NRI-Specific Reporting: NRE, NRO, FCNR, and Indian Investments
US-based NRIs face a particularly complex reporting landscape. NRE savings and fixed deposit accounts must be reported on both FBAR and Form 8938 if applicable thresholds are met, and interest earned must be reported as ordinary income on Schedule B of Form 1040 despite being exempt from Indian income tax. NRO accounts are similarly reportable, and interest is taxable in the US. Indian mutual fund folios present additional complexity: Indian mutual funds are classified as Passive Foreign Investment Companies (PFICs) under US tax law, which imposes punitive default tax treatment on unreported gains and requires annual elections to avoid the PFIC penalty regime. This is one of the most technically demanding cross-border tax issues for NRIs and requires specialist professional advice.
Schedule B, Part III: Foreign Account Disclosure on Your Tax Return
Schedule B, Part III of Form 1040 asks whether you had a financial interest in or signature authority over a financial account located in a foreign country at any time during the tax year. Answering "Yes" does not automatically trigger an FBAR filing obligation, but the disclosure must be made truthfully regardless of the FBAR threshold. Answering "No" when foreign accounts exist can constitute a false statement on a federal tax return, with its own criminal law implications independent of the FBAR penalties.
Penalties for Non-Compliance
The penalty regime for failures to report foreign income and foreign financial accounts is among the most severe in the US tax code. For FBAR non-willful violations, penalties of up to $10,000 per violation per year apply. For willful violations, penalties can reach the greater of $100,000 or 50% of the account balance per violation per year, potentially exceeding the total value of the unreported accounts. Criminal prosecution for willful FBAR violations carries penalties of up to $250,000 in fines and five years of imprisonment. FATCA Form 8938 failures carry initial penalties of $10,000, increasing to $50,000 for continued non-compliance.
Catching Up on Missed Filings: IRS Amnesty Programs
NRIs who have failed to file FBARs or report foreign income in prior years can regularize their compliance through IRS voluntary compliance programs. The Streamlined Filing Compliance Procedures allow taxpayers who can certify that their failure was non-willful to file amended returns and delinquent FBARs for the three most recent tax years, paying a single miscellaneous offshore penalty of 5% for the domestic version, or no penalty for the offshore version for those living outside the US. The Delinquent FBAR Submission Procedures allow taxpayers current on their tax returns but with missed FBARs to file the missing reports with an explanatory statement. Acting proactively before IRS contact is essential — the penalty regime for violations discovered through audit is far more severe than for voluntary disclosure.
Frequently Asked Questions
Do I need to report my Indian NRE account interest on my US tax return?
Yes. Interest earned on NRE accounts is exempt from Indian income tax under Section 10(4) of India's Income Tax Act, but this exemption has no effect on your US tax obligation. As a US person citizen, Green Card holder, or resident alien — you are required to report worldwide income to the IRS, including NRE account interest, as ordinary income on Schedule B of your Form 1040. The Indian tax exemption means no Foreign Tax Credit is available to offset the US tax on this income.
What is the difference between FBAR and FATCA Form 8938?
Both FBAR (FinCEN Form 114) and FATCA Form 8938 require disclosure of foreign financial accounts and assets, but they are separate requirements with different thresholds, account coverage rules, filing recipients, and penalty regimes. FBAR is filed with FinCEN if aggregate foreign account balances exceed $10,000 at any point during the year. Form 8938 is filed with the IRS as an attachment to Form 1040 if foreign financial asset values exceed $50,000 for US-based single filers. Both must be filed wherever both thresholds are met.
Can I use the Foreign Tax Credit to offset US tax on Indian income?
Yes, in most cases. Indian TDS deducted on NRO account interest, Indian capital gains tax paid on the sale of Indian stocks, or Indian income tax paid on rental income from Indian property can all generate Foreign Tax Credits that reduce your US tax liability on the same income. The credit is limited to the US tax attributable to the foreign income. For income exempt from Indian tax such as NRE account interest no Foreign Tax Credit is available, as no foreign tax was paid on that income.
What happens if I forget to file FBAR?
If your failure was non-willful, take corrective action as soon as possible before the IRS contacts you. The IRS Delinquent FBAR Submission Procedures allow taxpayers current on their tax returns and without unreported foreign income to file missing FBARs with an explanatory statement. The Streamlined Filing Compliance Procedures offer a structured amnesty path for those with both missed FBARs and unreported foreign income. Acting proactively before IRS contact is essential the penalty regime for willful violations discovered through audit is far more severe than for voluntary disclosure.
Do I need to report my Indian PPF account on FBAR?
Generally, yes. A Public Provident Fund (PPF) account in India is a foreign financial account for FBAR purposes because it is an account at a foreign financial institution over which the account holder has financial interest. If the aggregate value of all your foreign financial accounts including the PPF balance exceeded $10,000 at any point during the calendar year, you must file an FBAR and include the PPF account. The tax-exempt status of PPF interest under Indian law does not affect the FBAR filing requirement.
