Form 1040-NR guide for nonresident aliens

Form 1040-NR is the US Nonresident Alien Income Tax Return.You file it if you were a nonresident alien during the year and had a Form 1040-NR filing requirement, such as effectively connected income, reportable US-source income, a refund claim, or a treaty-based position

The 1040-NR tax form generally reports income that is taxable by the US for a nonresident alien, including US-source income and other income required to be reported under the nonresident alien rules. It does not cover worldwide income the way Form 1040 does.

Five mistakes trip up first-time filers most often:

• filing Form 1040 instead of Form 1040-NR, or vice versa
• skipping Schedule OI, which every filer must complete
• claiming the standard deduction when not eligible
• forgetting Form 8843 as an F, J, M, or Q visa holder
• missing Form 8833 when a treaty position must be disclosed

What is Form 1040-NR?

Form 1040-NR is the US federal income tax return nonresident aliens use to report income taxable by the US under the nonresident alien rules.

It generally applies to individuals who are nonresident aliens for US tax purposes – including those who do not meet the green card or substantial presence tests, subject to applicable statutory exceptions and treaty rules – and who have US-source income, a US trade or business, or a refund or treaty position to claim.

The IRS Form 1040NR rules run parallel to Form 1040, but reach different income levels. Line-by-line guidance is in the instructions for Form 1040-NR, and the residency and sourcing framework sits in Publication 519.

Form 1040-NR and Form 1040 apply to different taxpayers and reach different income.

 

Based on a TFX client scenario: a French researcher on a J-1 visa held US dividend-paying stocks in 2025 and received $12,000 in dividends. Her broker withheld 30% at source, but the US–France treaty caps the rate at 15%. She has no US wages. She still files the tax form 1040-NR – her only reason is to reclaim the 15% overwithholding.

For a walkthrough of the underlying Form 1040, see our guide on Form 1040 for individual taxpayers.

What is Form 1040-NR used for?

The return is used to calculate US federal income tax on income that is taxable by the US for a nonresident alien.

That includes US wages, income from a US trade or business (including income from services performed in the United States), rental income from US real property, US-source dividends, interest, royalties, taxable scholarships and fellowships, and certain capital gains.

The same return is also used to reclaim over-withheld tax, claim a lower treaty rate on FDAP income, and disclose treaty-based return positions on Form 8833.

What's the difference between Form 1040 and Form 1040-NR?

Which return you file depends on your alien status, not on where the income came from. US citizens and resident aliens report worldwide income on Form 1040. Nonresident aliens report their US-taxable income on Form 1040-NR under two separate regimes – ECI and FDAP.

The two returns diverge on five decision points.

 

Rule of thumb: if you are a US resident for the entire tax year, you generally file Form 1040. If you are a nonresident for the entire year, you generally file Form 1040-NR. If your residency status changes during the year, you may need a dual-status return.

Three quick examples show how the same rule produces different results.

1. Student. A Chinese graduate student on F-1 status in her third calendar year is generally an exempt individual for the substantial presence test and remains a nonresident alien. If she has a Form 1040-NR filing requirement – for example, because of taxable US wages – she files Form 1040-NR and Form 8843.
2. Investor. A UK resident with zero US days receives $8,000 in US dividends withheld at 30%. He files Form 1040-NR only if he wants to reclaim the 15% overwithholding under the US–UK treaty.
3. Remote worker. A German developer performs all her work from Berlin for a US employer. Because the services were physically performed outside the US, the wages are generally foreign-source for a nonresident alien. If she has no other US filing trigger, she generally would not need to file Form 1040-NR.

For a deeper split, see our guide on US tax rules for resident and nonresident aliens.

Who needs to file Form 1040-NR?

You generally must file if you were engaged in a US trade or business during the year, had another Form 1040-NR filing requirement, or want to claim a refund or treaty benefit. In some cases, income fully satisfied by withholding does not eliminate the filing requirement.

Common filing triggers by filer type:

• Wage earners. Nonresident aliens with US wages subject to income tax withholding.
• Individuals engaged in a US trade or business. Nonresident aliens with effectively connected income from services or another US trade or business generally must file Form 1040-NR. Separate rules determine whether any US self-employment tax applies.
• Investors. Nonresident aliens with US rental income, US real property gains, or FDAP income that was under-withheld.
• Students and scholars. F, J, M, or Q visa holders with US wages, taxable scholarships, or treaty-exempt income to report.
• Refund seekers. Nonresident aliens whose only US income was over-withheld FDAP, and who want the excess back.

Not every nonresident alien with US-source income has to file. A nonresident whose only US income was FDAP fully withheld at the correct rate, with no refund claim and no other US activity, generally has no Form 1040-NR obligation.

How do I know if I am a resident or nonresident alien?

Your status is set by two tests.

• The green card test treats you as a resident from your first day as a lawful permanent resident.
• The substantial presence test treats you as a resident if you were physically in the US for at least 31 days in the current year and 183 weighted days over the current year plus the two years before.

The weighting counts all days in the current year, one-third of the days in the prior year, and one-sixth of the days in the second prior year.

A short diagnostic:

• Held a green card at any point in the year → resident.
• Did not hold a green card, but met the 183-day weighted count → resident.
• Neither → nonresident alien.

TFX client scenario:

A software engineer on an H-1B visa who first satisfies the substantial presence rules during 2025 may become a dual-status taxpayer, with nonresident and resident portions of the year determined under the residency starting date rules

For a full breakdown of alien tax status, see our guide on how to define your US alien tax status.

Non-US citizens with US source income

Having US-source income does not automatically require a Form 1040-NR filing. Whether you need to file depends on factors such as whether you were engaged in a US trade or business, whether you have a filing requirement apart from withholding, and whether you want to claim a refund or treaty position.

US-source income categories that commonly reach nonresident aliens:

• wages from services performed in the US
• rental income from US real property
• dividends and interest from US payers
• royalties from US sources
• taxable scholarships and fellowships
• capital gains taxable under IRC § 871(a)(2) or FIRPTA

The two-track split matters. ECI (from a US trade or business) is reported on page 1 and taxed at graduated rates on net income. FDAP (passive US-source payments) is reported on Schedule NEC at a flat 30%, unless a treaty reduces the rate.

See our full breakdown of ECI vs. FDAP treatment for the classification rules that decide the filing outcome.

International students and scholars (F, J, M, Q visas)

Students and scholars on F, J, M, or Q visas are generally treated as exempt individuals under the substantial presence test, which usually keeps them nonresident aliens even after long stays in the US.

The exemption is not open-ended – it runs on calendar-year counting with prior-year lookback limits set by IRS rules.

The core rules:

• Students on F, J, M, or Q. Generally exempt individuals for their first five calendar years in the US in student status. Any part of a year counts as a full year.
• Teachers and researchers on J or Q. Generally exempt for two out of the last six calendar years.
• Form 8843. Required for any exempt individual who was in the US in F, J, M, or Q status, even if no US income was earned.

If you had US wages, a taxable scholarship, or another taxable US-source item, you file Form 1040-NR and attach Form 8843. If you had no US income at all, Form 8843 is filed by itself, by June 15 of the following year.

Common documents to gather before filing: Form W-2, Form 1042-S, Form 1098-T, passport, visa, and I-20 or DS-2019.

For a full student-side walkthrough, see our guide on F-1 international student tax returns.

Foreign investors (real estate and stocks)

Not every US investment produces a 1040-NR filing requirement. What matters is whether the income is ECI or FDAP, whether withholding satisfied the tax, and whether FIRPTA applies to a real property sale.

How each investment type is generally treated for nonresident aliens:

 

See our guides on capital gains for nonresidents and what FIRPTA is for the mechanics that decide the filing outcome.

Do remote workers need to file 1040NR?

For a nonresident alien, wages are sourced to where the work was physically performed, not to where the employer is located. Work done entirely outside the US is generally foreign-source and does not trigger a Form 1040-NR filing.

Three common patterns:

• Work performed in the US generally produces US-source wages. Whether Form 1040-NR must be filed depends on the nonresident filing rules, not solely on whether withholding covered the tax.
• Work performed abroad for a US employer. Wages are foreign-source for a nonresident alien. Generally no 1040-NR filing requirement.
• Self-employment tied to a US trade or business. ECI reporting applies, even if the taxpayer is not on payroll.

Working on a tourist visa (B-1 or B-2) is not authorized employment and may have immigration consequences separate from the tax result. Digital nomads should track US days carefully, because a stretch of in-US work can create both a substantial-presence issue and a US-source wage exposure.

Understanding income types: ECI vs. FDAP

Nonresident aliens face two categories of US income.

• Effectively connected income (ECI) is income treated as connected with a US trade or business under the Internal Revenue Code and related rules, and it is generally taxed at graduated rates from 10% to 37% on net income.
• FDAP – fixed, determinable, annual, or periodical income – is generally taxed at a flat 30% on the gross amount, unless a treaty lowers the rate.

ECI vs. FDAP side by side.

 

Two rules of thumb help avoid misclassification:

• Not all US interest is FDAP. Portfolio interest and most US bank deposit interest paid to a nonresident alien are exempt from the 30% tax.
• Rental income from US real property is FDAP by default. To get net-basis treatment and deduct mortgage interest, taxes, depreciation, and repairs, the taxpayer must make an IRC § 871(d) election on Form 1040-NR.

For the full FDAP framework, see our guide on FDAP income and withholding.

Key components of Form 1040-NR (schedules)

Every 1040-NR return has a page 1 that reports ECI, plus schedules that report other categories and disclosures. Schedule OI is required for every filer. Other schedules attach only if the underlying facts apply.

Which schedule you need, at a glance:

 

Before you assemble the return, gather Form W-2 or Form 1042-S for each source of US income, passport and visa records, prior-year returns if available, and a copy of the current Form 1040-NR.

How to file Form 1040-NR

Filing is a five-step process, whether you e-file or paper file. The current Form 1040-NR instructions cover every line, but the practical order below prevents most rejections.

1. Confirm your residency status. Run the green card and substantial presence tests before choosing the form.
2. Collect your documents. Form W-2, Form 1042-S, Form 1099s where applicable, passport, visa, and prior-year returns.
3. Choose e-file or paper. Form 1040-NR can be e-filed through participating providers. 1040-NR online filing is supported through specialist software like Sprintax and Glacier Tax Prep, and by tax preparers with IRS-approved software. Mainstream consumer software (TurboTax, H&R Block) generally does not support the form.
4. Complete the return. Enter ECI on page 1, FDAP on Schedule NEC, and always complete Schedule OI. Attach Form 8843 if you were an exempt individual, and Form 8833 if you are disclosing a treaty position.
5. Submit or mail. If you e-file, the software submits the return and any supported attachments. If you paper file, mail to the address in the following section.

If you do not have and are not eligible for a Social Security Number, apply for an Individual Taxpayer Identification Number (ITIN) using Form W-7. The Form W-7 is generally submitted together with the return, along with proof of identity and foreign status. A Certified Acceptance Agent can certify identity documents so you do not have to mail original passports.

For the online-filing landscape more broadly, see our guide on filing US taxes online from abroad.

Common Form 1040-NR filing issues:

• Filing without an SSN or ITIN. Attach Form W-7.
• Missing Schedule OI. Every filer needs it.
• Wrong treatment of rental income. Consider the section 871(d) election before defaulting to 30% FDAP.
• Missed treaty disclosure. Many treaty-based return positions require Form 8833, although Treasury regulations exempt certain common treaty claims from the disclosure requirement.

Where to file Form 1040-NR

If you e-file, you do not mail anything. If you paper file, the mailing address depends on whether you enclose a payment.

These addresses apply to the 2026 filing season – always verify the current mailing address in the latest Form 1040-NR instructions before mailing:

 

Two points to check before mailing:

• Private delivery services. Private delivery services cannot deliver to a P.O. Box. If you use FedEx, DHL, or UPS, verify the current IRS private-delivery street address for your exact Form 1040-NR filing situation before shipping.
• Timely-filed rule. For USPS, the postmark date is the filing date. Consider certified mail with return receipt if the deadline is close.

Addresses change between filing seasons. Check the current instructions for the 1040-NR or our guide on IRS mailing addresses for expats before sending.

1040NR deadlines and important dates

The 1040-NR due date for a 2025 calendar-year return depends on whether you received wages as an employee subject to US income tax withholding and whether you had an office or place of business in the US.

• April 15, 2026 – if you received US wages subject to income tax withholding, or you have an office or place of business in the US.
• June 15, 2026 – if you did not receive US wages subject to income tax withholding and did not have an office or place of business in the US. This also covers Form 8843 filers with no income to report.
• October 15, 2026 – if you file Form 4868 by the original due date to request a six-month extension of time to file.

Extensions do not extend the time to pay. Interest starts accruing on any unpaid tax from the original due date, even if the return is filed later.

A note on the older rule. Some earlier guidance tied the June 15 deadline to living outside the US. That is not the rule. What actually matters is whether the taxpayer received US wages subject to withholding or maintained an office or place of business in the US.

If you need to file Form 1040-NR late, do it as soon as possible. In many cases, filing within the time allowed under IRS regulations helps preserve certain deductions available to nonresident aliens. Different rules may apply depending on the type of claim.

See our guides on foreign country tax filing deadlines and how to file a tax extension for the extension mechanics.

Correcting mistakes and solutions

The most common 1040-NR errors are wrong residency status, missing Schedule OI, misreported income, and omitted treaty disclosures. Most are corrected by filing Form 1040-X with the corrected 1040-NR information attached.

Common issues and how to address them:

• Filed Form 1040 by mistake. Amend using Form 1040-X and attach a corrected Form 1040-NR.
• Missed Schedule NEC on FDAP income. File Form 1040-X to add the schedule and reconcile any overwithheld tax.
• Treaty position not disclosed on Form 8833. Amend to attach the form. Undisclosed treaty positions carry a $1,000 penalty per failure for individuals.
• Wrong SSN or ITIN. Correct the identifier and refile.

Refund claims from an amended return must generally be filed within 3 years of the original filing date to be honored.

Correcting mistakes

The amendment workflow is straightforward, but the order matters.

1. Identify the specific error and confirm the right correction.
2. Prepare a corrected Form 1040-NR reflecting the fix.
3. Complete Form 1040-X, using the three-column format (as originally filed, net change, corrected amount).
4. Attach the corrected schedules and any supporting statements.
5. Mail Form 1040-X – electronic amendment is available for some prior years, but nonresident amendments are generally paper-filed.

Do not amend if the IRS has already opened an examination of the return. In that case, work through the examination first.

For a broader walkthrough, see our guide on filing an amended return from abroad or our amended tax return service.

Deductions, credits, and tax treaties

Nonresident aliens generally cannot claim the standard deduction. Itemized deductions on Schedule A-NR are available but limited to items tied to US-source ECI, such as qualifying state and local income taxes and charitable contributions to qualified US organizations.

For tax years 2018–2025, personal casualty and theft losses are generally deductible only if attributable to a federally declared disaster. Most refundable credits available to residents are unavailable to nonresident aliens.

Tax treaties expand the picture. The US has income tax treaties with 68+ countries, and many of them reduce withholding on FDAP income, exempt specific income types, or allow deductions that would otherwise not apply.

Common treaty positions for individuals:

 

Treaty benefits are not automatic. Many treaty-based return positions require Form 8833 disclosure, although Treasury regulations exempt certain common claims. Form 8233 is used to secure treaty-reduced withholding on personal services income before it is paid. Documentation requirements vary by article and by income type.

For the underlying framework, see our guides on US tax treaties and foreign tax credit vs. deduction.

When to seek pro help

Straightforward 1040-NR situations – a single US-source wage stream, no treaty position, no real estate – can be filed independently with the right software. Certain situations carry enough downside risk that professional preparation is worth the cost.

Red flags that usually justify a professional:

• dual-status year (mid-year status change)
• FIRPTA recovery on a US real property sale
• multiple treaty positions or Form 8833 disclosures
• rental income where an ECI election is on the table
• late or amended 1040-NR filings
• ITIN application filed together with the return

TFX prepares Form 1040-NR end-to-end, including Schedule NEC treaty claims, FIRPTA recovery, ITIN applications on Form W-7, and dual-status statements. Every return is reviewed by a CPA or EA.

A CPA and a tax attorney cover different ground – which one fits depends on whether the issue is a filing problem or a legal one.
