IRS Form 1040-NR – U.S. Nonresident Alien Income Tax Return – As a nonresident alien with income tied to the United States, navigating U.S. tax obligations can feel overwhelming. IRS Form 1040-NR, officially known as the U.S. Nonresident Alien Income Tax Return, is the key document you’ll use to report your earnings and ensure compliance. Whether you’re an international student, a foreign worker, or an investor with U.S.-sourced income, understanding this form is essential to avoid penalties and potentially claim refunds. In this comprehensive guide, we’ll break down everything you need to know about Form 1040-NR for the 2025 tax year, based on the latest IRS guidelines.
What Is IRS Form 1040-NR?
Form 1040-NR is the specialized tax return for nonresident aliens who have U.S.-sourced income. Unlike the standard Form 1040 used by U.S. residents and citizens, this form is tailored for individuals who are not U.S. residents but must report income subject to U.S. taxation. It divides income into two main categories:
- Effectively Connected Income (ECI): This includes wages, business profits, or other earnings directly tied to a U.S. trade or business. ECI is taxed at graduated rates similar to those for U.S. residents.
- Fixed, Determinable, Annual, or Periodical (FDAP) Income: This covers items like dividends, interest, royalties, and rents not connected to a U.S. business. It’s typically taxed at a flat 30% rate, unless reduced by a tax treaty.
The form also accounts for treaty benefits, which can exempt or reduce taxes on certain income types. For the 2025 tax year, the form includes updates to align with recent tax law changes, such as adjustments to qualified dividends and digital asset reporting.
Who Needs to File Form 1040-NR?
Not every nonresident alien must file, but you likely do if you meet any of these criteria:
- You were engaged in a U.S. trade or business and had ECI (even if it resulted in a loss or was exempt under a treaty).
- You had U.S.-sourced FDAP income that wasn’t fully withheld at the source.
- You’re filing on behalf of a deceased nonresident alien, estate, or trust.
- You received scholarships, fellowships, or other grants considered taxable.
- You owe additional taxes, such as self-employment tax under an international Social Security agreement or taxes on transportation income.
Exceptions apply: For instance, nonresident students or trainees under certain visas may not need to file if their only income is exempt. Indian students and business apprentices might qualify for a standard deduction under the U.S.-India tax treaty. If you’re a dual-status taxpayer (nonresident for part of the year and resident for another), you’ll file Form 1040-NR if your nonresident period dominates, attaching a statement for the resident portion.
To determine your residency status, check if you pass the green card test or substantial presence test (generally, 183 days or more in the U.S. over three years). U.S. nationals (e.g., from American Samoa) may also use this form.
Key Differences Between Form 1040 and Form 1040-NR
While both forms report income, Form 1040-NR has unique features:
| Feature | Form 1040 (for Residents) | Form 1040-NR (for Nonresidents) |
|---|---|---|
| Filing Status Options | Single, Married Filing Jointly, Head of Household, etc. | Limited to Single, Married Filing Separately, Qualifying Surviving Spouse (with restrictions for certain countries), Estate, or Trust. |
| Income Reporting | All worldwide income. | Only U.S.-sourced income; ECI on main form, FDAP on Schedule NEC. |
| Deductions | Full standard or itemized deductions. | Itemized deductions only for ECI; standard deduction limited (e.g., for Indian treaty beneficiaries). |
| Credits | Broad access to credits like Earned Income Credit. | Limited credits, e.g., child tax credit only for residents of Canada, Mexico, South Korea, or India (partial); no EIC. |
| Tax Rates | Graduated for all income. | Graduated for ECI; 30% flat (or treaty rate) for FDAP. |
These differences ensure nonresidents only report and pay taxes on U.S.-related income.
How to Fill Out Form 1040-NR: Step-by-Step Guide?

- Personal Information: Enter your name, identifying number (SSN or ITIN), foreign address, and filing status. Answer the digital assets question (e.g., if you received cryptocurrency as income).
- Income Section: Report ECI on lines 1–9 (e.g., wages on 1a, dividends on 3a). Use Schedule 1 for additional income like business profits or scholarships. FDAP goes on Schedule NEC, with treaty reductions in column (d). Exempt income under treaties is noted on line 1k and Schedule OI (Other Information).
