Most people who search for this form share the same worries:
- Do I have to file at all?
- Which income goes on the return?
- Can I claim a treaty benefit or a refund?
- How do I avoid the wrong form or a missing attachment?
This guide covers tax year 2025 returns, generally filed in 2026. It walks through who files, how income is taxed, the filing steps, deadlines, and common errors.
Key Takeaways
- Confirm nonresident alien status first. It decides whether Form 1040-NR applies.
- Filing triggers include a US trade or business, under-withholding, refund claims, and treaty positions.
- Effectively connected income (ECI) and FDAP income are taxed differently.
- Check deadlines, schedules, and mailing addresses against current IRS guidance.
Form 1040-NR Explained: Purpose, Scope, and Required Information
Form 1040-NR is titled "U.S. Nonresident Alien Income Tax Return." Nonresident aliens use it to report income that the US taxes under nonresident rules.
The scope differs sharply from a resident return. Resident aliens are generally taxed on worldwide income. Nonresident aliens are generally taxed on US-source income and certain foreign-source effectively connected income (ECI), according to Publication 519.
What the return collects
The 2025 return asks for:
- Name, identifying number, address, and filing status
- ECI and non-ECI income
- Deductions, tax, and credits
- Withholding and estimated payments
- Refund or balance due
It also asks about your country of tax residence, visa details, and time spent in the US.
Schedules and related forms
Which ones apply depends on your facts:
- Schedule OI collects other information. Item L reports income claimed exempt under a treaty.
- Schedule NEC reports tax on non-ECI income.
- Schedule A lists allowable itemized deductions.
- Form 8843 claims exclusion of US presence days for exempt individuals.
- Form 8833 discloses treaty positions that override or modify the Internal Revenue Code.
- Form W-7 requests an ITIN.
Always work from the current IRS form, instructions, and Publication 519. Older versions and third-party summaries go stale quickly.
Who Needs to File Form 1040-NR?
Residency status
You are a US tax resident for 2025 if you meet either test:
- Green Card test: you were a lawful permanent resident at any time during 2025.
- Substantial presence test: at least 31 days in the US during 2025, and a weighted total of 183 days or more. That counts all 2025 days, one-third of 2024 days, and one-sixth of 2023 days.
If you meet neither, you are a nonresident alien. Physical location alone doesn't decide which return you file.
Common filing triggers
For 2025, filing is generally required if you are a nonresident alien engaged in a US trade or business, even with no income or only treaty-exempt income. It is also generally required for US-source income that withholding doesn't fully cover. Typical triggers:
- Wages for services performed in the US
- US rental or real estate income
- Taxable scholarships
- Under-withholding
- Refund claims for overwithholding
- Treaty-based positions
When you may not need to file
The 2025 Form 1040-NR instructions say no return is required if you have no US trade or business, no ECI (effectively connected income), and withholding fully satisfies the tax. You may still file to claim a refund.
Publication 519 also lists three no-return exceptions:
- Certain temporarily present F, J, M, or Q students, teachers, or trainees with no taxable income
- Qualifying students or business apprentices under US-India treaty Article 21(2), within income limits
- Partners whose partnership wasn't engaged in a US trade or business and whose Schedule K-1 shows only non-ECI income
Special residency situations
- Dual-status years: you are a nonresident for part of the year and a resident for the rest. The resident return is the main return, with a statement showing income for the nonresident period.
- Students and scholars: F, J, M, and Q visa holders can generally exclude days for their first five calendar years if temporarily present and substantially complying. Form 8843 documents the exclusion.
- Treaty positions: these can change whether you file, and what you attach.
How Is Form 1040-NR Income Taxed?
ECI versus FDAP
ECI comes from a US trade or business, including wages for US services. It is taxed at graduated rates after allowable deductions.
FDAP income (fixed, determinable, annual, or periodical) includes dividends, royalties, certain interest, pensions, and passive rents. When it isn't effectively connected, it is generally taxed at 30% of gross. No deductions, no netting. Treaty rates may be lower.
Why sourcing matters
Pay for work physically performed in the US is generally US-source. Work done partly inside and partly outside the US gets allocated.
Multiyear compensation is generally allocated by US workdays divided by total workdays. Work done abroad for a US employer follows different rules, so check the sourcing rule for each income type.
Deductions and credits
Limits are tighter for nonresident aliens:
- No standard deduction, except certain US-India treaty Article 21(2) students and apprentices who don't itemize
- Itemized deductions generally require ECI and are limited to amounts allocated to it
- No earned income credit for anyone who was a nonresident for any part of the year
- Education credits generally unavailable
- Child tax credit only for specified categories
Treaty benefits
Treaties can reduce withholding, exempt certain income, or change the result. Two sets of forms matter, and they go to different places:
| Form | Use | Goes to |
|---|---|---|
| W-8BEN | Treaty benefits on non-service income | Withholding agent |
| 8233 | Treaty benefits on personal services income | Withholding agent |
| 8833 | Treaty position disclosure | Filed with the return |
Special situations
- Scholarships: Degree candidates may exclude required tuition, fees, books, and supplies. Room, board, and service pay are taxable; non-service awards usually face 14% withholding or a lower treaty rate.
- Rental property: Elect under IRC section 871(d) to treat rent as ECI, which allows deductions and graduated tax on net income. File the election with a return statement; it generally continues until revoked.
- US real property sales: Gains and losses are treated as effectively connected. Report Form 8288-A withholding on the return.
Verify each election and form against current IRS guidance before you file.
How to Prepare and File Form 1040-NR: Step-by-Step
Gather your documents
- Forms W-2, 1042-S, and any 1099s
- Brokerage and rental records
- Passport and visa information
- US entry and exit dates
- Prior-year returns
- Treaty documentation
- Records supporting deductions
Confirm your taxpayer ID
Use an SSN if you have one or are eligible. Don't file Form W-7 in that case. If an SSN application is pending, wait for the Social Security Administration's decision. Apply for an ITIN only if you aren't eligible for an SSN.
For a first ITIN application, attach Form W-7 to the front of the return with identity and foreign-status documents. A passport is the only stand-alone document. Otherwise you need a combination that generally includes a photo ID.
Submit originals or copies certified by the issuing agency. Certifying acceptance agents can authenticate most documents.
Preparation order
- Confirm residency status.
- Identify your filing trigger.
- Source each income item.
- Classify it as ECI or FDAP.
- Decide whether treaty treatment or extra disclosures apply.
- Complete the main return, then Schedule OI, Schedule NEC if applicable, itemized deductions, and Forms 8843 and 8833 where required.
- Reconcile withholding from your W-2s and 1042-S forms against the tax shown.
E-file or paper
The 2025 instructions direct filers to a preparer or commercial software. E-file works for eligible returns, not every fact pattern. Paid preparers generally must e-file Form 1040-NR, subject to exceptions. An initial ITIN application means mailing a paper return with Form W-7 attached.
For 2026 filings, the 2025 instructions list these paper addresses:
- No payment: Department of the Treasury, IRS, Austin, TX 73301-0215
- With payment: IRS, P.O. Box 1303, Charlotte, NC 28201-1303
Addresses can change, so confirm on the IRS site before mailing.
Sign, pay, and keep records
Sign the return before you submit it.
You can pay by:
- Bank account
- Card
- Same-day wire
- Check or money order
Fees apply to some methods.
Keep complete copies of the return and supporting documents. The IRS generally has three years to assess tax, or six years for substantial omissions. Hold property records through the limitations period for the year you dispose of the asset.
Deadlines, Extensions, and Common Form 1040-NR Errors
Tax year 2025 deadlines
- April 15, 2026: employees with wages subject to US income tax withholding
- June 15, 2026: filers without wages subject to US withholding
- Form 8843: due by the applicable Form 1040-NR date. If no return is required, mail it separately to IRS Austin, TX 73301-0215.
Extensions
A timely Form 4868 gives an automatic six months to file, not to pay. A return due April 15 moves to October 15, 2026. A June 15 return moves to December 15, 2026, using line 9. Interest and penalties still accrue on unpaid tax from the original date.
The failure-to-file penalty is generally 5% of tax due per month, up to 25%. The failure-to-pay penalty is 0.5% per month, up to 25%.
Frequent errors
- Filing Form 1040 instead of Form 1040-NR
- Omitting Schedule OI or Form 8843
- Claiming a standard deduction you can't take
- Misclassifying ECI and FDAP
- Overlooking Form 8833
- Failing to reconcile withholding
- Using the wrong or missing SSN or ITIN
Correcting a return
Use Form 1040-X to amend a Form 1040-NR, or to fix filing the wrong return type. Paper amendments need the corrected Form 1040-NR attached. An omitted treaty claim or income item is handled the same way. State filing rules are separate, so review them on their own.
Final Form 1040-NR Filing Checklist
Work through these items before you file:
- Confirm nonresident status
- Identify your filing trigger
- Classify US income as ECI or FDAP
- Review treaty eligibility
- Verify SSN or ITIN
- Attach conditional forms (8843, 8833, W-7)
- Reconcile withholding
- Check the current deadline
- Keep proof of filing
Some situations are hard to handle alone: dual-status years, business or rental income, ITIN applications, treaty disclosures, amended returns, or unclear residency.
