Form 1040-NR is generally filed by a nonresident alien who has a U.S. federal income tax filing requirement for a given tax year. This can include a nonresident alien with taxable U.S.-source income, a person engaged in a U.S. trade or business, certain international students or scholars with taxable income, someone claiming a refund of U.S. tax withheld, or a representative filing for a deceased person, estate, or trust that would have had to use Form 1040-NR.
The exact answer depends on federal tax residency, income type, withholding, treaty position, and the tax year involved. Form 1040-NR is not based only on visa status, nationality, or whether someone lived in the United States for the full year.
What Form 1040-NR Is Used For
Form 1040-NR, U.S. Nonresident Alien Income Tax Return, is the federal income tax return used by nonresident alien individuals, and in some cases nonresident alien estates or trusts, to report income connected with U.S. tax rules. The IRS describes the form on its official Form 1040-NR page.
The form is used for income that may be taxable to a nonresident alien under U.S. federal tax law. This may include wages, taxable scholarship or fellowship grants, business income, rental income, dividends, certain capital gains, partnership income, and other U.S.-source income, depending on the facts.
Form 1040-NR is different from Form 1040. A person who is a resident alien for federal tax purposes generally uses Form 1040, not Form 1040-NR. A person who is a nonresident alien for federal tax purposes generally looks first to Form 1040-NR and its official instructions.
The Main Groups Who May File Form 1040-NR
The IRS instructions list several situations where Form 1040-NR may be required. The table below summarizes common categories in plain English. It does not replace the official Instructions for Form 1040-NR.
| Possible Filer | Why Form 1040-NR May Matter | Common Documents Involved |
|---|---|---|
| Nonresident alien with taxable U.S.-source income | The person may need to report income that is subject to U.S. federal income tax. | W-2, 1042-S, 1099, Schedule K-1, records of U.S.-source income |
| Nonresident alien engaged in a U.S. trade or business | Effectively connected income is generally reported on Form 1040-NR. | W-2, business records, Schedule C, partnership statements |
| F-1, J-1, M-1, or Q visa student, teacher, or trainee with taxable income | Some nonresident students and exchange visitors may have taxable wages, scholarship income, or other income. | W-2, 1042-S, Form 8843, school tax documents |
| Person claiming a refund of U.S. tax withheld | A return may be filed to claim back federal tax that was withheld in excess of the tax owed, if the person is eligible. | 1042-S, W-2, 1099, withholding records |
| Dual-resident taxpayer claiming treaty nonresident treatment | A person treated as a U.S. resident under domestic rules may, in limited cases, claim treaty-based nonresident treatment. | Form 1040-NR, Schedule OI, possibly Form 8833 |
| Representative of a deceased nonresident alien | A personal representative may file if the deceased person would have had to file Form 1040-NR. | Final income records, withholding forms, representative documents |
| Representative of a nonresident alien estate or trust | Some nonresident alien estates or trusts may have a Form 1040-NR filing requirement. | Estate or trust income records, EIN, related schedules |
Start with Federal Tax Residency
The first question is usually whether the person is a nonresident alien or resident alien for federal income tax purposes. This is a tax classification, not a general immigration label.
Under IRS rules, a person who is not a U.S. citizen is generally classified as a resident alien if they meet the green card test or the substantial presence test. A person who does not meet either test is generally a nonresident alien for federal tax purposes, unless a special rule or election applies. The IRS explains these concepts in Publication 519, U.S. Tax Guide for Aliens.
The substantial presence test counts days of presence in the United States using a formula. Some people, such as certain students, teachers, trainees, and other “exempt individuals,” may be able to exclude certain days from that count. The word “exempt” in this context does not mean the person is exempt from all U.S. tax. It means certain days may be excluded for the residency test.
Because residency classification can change from one tax year to another, a person may file Form 1040-NR for one year and Form 1040 for another year. The answer depends on the facts for that year.
Nonresident Aliens with U.S.-Source Income
A nonresident alien may need to file Form 1040-NR when they have income from U.S. sources that is subject to U.S. tax. The IRS states on its Taxation of Nonresident Aliens page that nonresident aliens generally report income that is subject to tax, such as wages, tips, scholarship and fellowship grants, dividends, and other income.
For nonresident alien tax purposes, income is often discussed in two broad categories: effectively connected income and FDAP income.
- Effectively connected income, or ECI: Income connected with a U.S. trade or business. It is generally taxed after allowable deductions at graduated rates.
- FDAP income: Fixed or determinable annual or periodical income, such as some dividends, rents, royalties, or similar payments. FDAP income that is not effectively connected with a U.S. trade or business is generally subject to withholding, often at 30% unless a lower treaty rate or other rule applies.
These categories matter because Form 1040-NR separates income that is effectively connected with a U.S. trade or business from income that is not effectively connected. Some income may appear on the main Form 1040-NR, while other income may appear on Schedule NEC.
Nonresident Aliens Engaged in a U.S. Trade or Business
A nonresident alien who is engaged in a trade or business in the United States during the tax year may need to file Form 1040-NR. This can include employment or other activity that creates effectively connected income.
In many everyday cases, this means a nonresident alien who worked in the United States and received wages may receive Form W-2 and may need to review Form 1040-NR filing rules. It can also include some self-employment or business activity, although self-employment tax rules for nonresident aliens are narrower and may depend on totalization agreements and other facts.
The phrase “engaged in a U.S. trade or business” can be technical. A person should not rely only on ordinary meaning. The official instructions and qualified tax help can be useful when income is from business, consulting, freelancing, partnerships, or services performed partly inside and outside the United States.
International Students, Scholars, Teachers, and Trainees
Many international students and exchange visitors first encounter Form 1040-NR because they are in the United States under F, J, M, or Q status. Some remain nonresident aliens for federal tax purposes for a period of time because certain days may be excluded from the substantial presence test.
A nonresident student, teacher, or trainee may need to file Form 1040-NR if they have income subject to U.S. tax. Common examples can include taxable wages from campus employment, taxable scholarship or fellowship grants, taxable stipend payments, or other U.S.-source income. The exact result depends on the income type and the tax year.
Some international students and scholars also file Form 8843. Form 8843 is not the same as Form 1040-NR. The IRS explains on its Form 8843 page that the form is used to explain the basis for excluding days of presence in the United States for the substantial presence test.
A person may need Form 8843 even when they do not have a Form 1040-NR filing requirement. A person may also need both forms if they are a nonresident alien with taxable income and are claiming exempt individual day treatment.
People Claiming a Refund of U.S. Tax Withheld
Some nonresident aliens file Form 1040-NR because U.S. federal tax was withheld from income and they may be eligible to claim a refund. This can happen when withholding was higher than the final tax liability, when a treaty rate may apply, or when income was reported on a form such as Form 1042-S.
A refund claim usually needs documentation. For example, the Form 1040-NR instructions explain that a person claiming a refund of tax withheld at source generally attaches acceptable proof of withholding, such as Form 1042-S or a relevant Form 1099. The taxpayer may also need to complete Schedule OI and provide treaty information if the claim depends on a tax treaty.
Filing for a refund does not mean every withheld amount is refundable. The result depends on the type of income, the withholding rule, any treaty position, and whether the return is completed with the required support.
People with Tax Treaty Claims
Some nonresident aliens file Form 1040-NR because they are reporting a tax treaty position or claiming treaty-based treatment for certain income. U.S. tax treaties can reduce or exempt U.S. tax on specific types of income for eligible residents of treaty countries. The IRS provides treaty texts through its Tax Treaties page.
Treaty benefits are not based only on citizenship. They usually depend on treaty residency, the article of the treaty, the income type, time limits, and other conditions. A person claiming treaty treatment on Form 1040-NR may need to provide details on Schedule OI and, in some cases, attach Form 8833.
Tax treaties are one area where careful wording matters. A general article can explain the concept, but it cannot decide whether a reader personally qualifies for a treaty benefit.
Representatives of a Deceased Person, Estate, or Trust
Form 1040-NR is not used only by living individuals filing for themselves. A personal representative may file Form 1040-NR for a deceased person who would have had to file the form for the tax year. The representative may be an executor, administrator, or another person responsible for the deceased person’s property.
In some cases, a representative of a nonresident alien estate or trust may also file Form 1040-NR. These situations can involve rules that differ from a standard individual return. The official instructions should be checked closely, and qualified help may be useful.
Common Forms Connected to Form 1040-NR
People who file Form 1040-NR often receive or use other forms. These forms help identify income, withholding, tax residency claims, or taxpayer identification numbers.
| Form | What It Generally Shows or Does | How It Relates to Form 1040-NR |
|---|---|---|
| Form W-2 | Reports wages and tax withheld by an employer. | Wages may be reported on Form 1040-NR if the filer is a nonresident alien with taxable wages. |
| Form 1042-S | Reports certain U.S.-source income paid to foreign persons and related withholding. | Often used for scholarships, fellowships, treaty-exempt income, royalties, dividends, or other payments to foreign persons. |
| Form 8843 | Explains a claim to exclude days of U.S. presence for the substantial presence test. | May be filed with Form 1040-NR or separately, depending on the person’s filing situation. |
| Form W-8BEN | Certifies foreign status to a withholding agent or payer. | Usually given to the payer, not filed with Form 1040-NR, but it may affect withholding before filing. |
| Form W-7 | Applies for or renews an ITIN. | May be needed when a filer has a federal tax filing need but is not eligible for an SSN. |
| Form 8833 | Discloses certain treaty-based return positions. | May be attached to Form 1040-NR in some treaty situations. |
| Schedule OI | Collects other information for Form 1040-NR, including immigration, residency, and treaty details. | Usually part of the Form 1040-NR package. |
| Schedule NEC | Reports income not effectively connected with a U.S. trade or business. | Used for certain FDAP-type income and related tax calculations. |
When Form 1040-NR May Not Be Required
Not every nonresident alien files Form 1040-NR every year. In some cases, a nonresident alien student, teacher, or trainee with no income subject to U.S. tax may not have to file Form 1040-NR, although Form 8843 may still be required.
A nonresident alien who received only certain income that was fully withheld at the correct rate may also have a different filing result. However, the rules are detailed. A person who received Form 1042-S, Form 1099, partnership income, real estate income, or any income with uncertain sourcing should check the official instructions rather than assuming no return is needed.
The safest general statement is this: Form 1040-NR is tied to federal tax residency and U.S. tax-reportable income or claim positions. It is not triggered by being a foreign citizen alone.
Federal Form 1040-NR and State Tax Are Separate
Form 1040-NR is a federal tax form. State income tax rules are separate. A person may be a nonresident alien for federal tax purposes and still need to review state resident, nonresident, or part-year resident filing rules.
States use their own forms, definitions, and income sourcing rules. For example, a state may tax income earned from services performed in that state, rental income from property located in that state, or other state-source income. Some states have no broad individual income tax, while others have detailed nonresident and part-year resident rules.
The IRS maintains a directory of state government tax websites, which can help readers find the official tax agency for a specific state. State rules should be checked directly because federal Form 1040-NR does not settle state filing duties.
Examples of Situations That Often Lead to Form 1040-NR
The following examples are general and simplified. They show common patterns, not personal filing advice.
- A nonresident student worked on campus. The student received taxable wages and a Form W-2. Form 1040-NR may be relevant because wages can be U.S.-source income subject to tax.
- A visiting scholar received a taxable stipend. The payer issued Form 1042-S. The scholar may need to review whether the income is taxable, treaty-exempt, or reportable on Form 1040-NR.
- A foreign investor received U.S. dividends. The income may be FDAP income. If withholding was not correct, or a refund is being claimed, Form 1040-NR may be involved.
- A nonresident alien performed services in the United States. Payment for services performed in the United States may create U.S.-source income. The form used can depend on whether the income is wages, independent services, or another category.
- A person changed U.S. tax residency during the year. Dual-status or treaty-residency issues may require careful review of the Form 1040-NR instructions and Publication 519.
- A personal representative is handling a final return. If the deceased person would have had to file Form 1040-NR, the representative may need to file it for that year.
Common Misunderstandings About Who Files Form 1040-NR
Visa Status Alone Does Not Decide the Tax Form
A visa category can affect the analysis, especially for students and exchange visitors, but it does not answer every tax question by itself. Federal tax residency, days of presence, income type, and treaty rules also matter.
No Income Does Not Always Mean No Tax Form
A nonresident alien with no income subject to U.S. tax may not need Form 1040-NR in some cases. But certain students, teachers, or trainees may still need Form 8843 to support exempt individual day treatment.
Withholding Is Not the Same as Final Tax
Tax withheld by an employer, university, broker, or other payer is not always the final tax result. A return may show additional tax due, no balance due, or a refund, depending on the facts.
A Tax Treaty Is Not Automatic
A treaty benefit may apply only if the person meets the treaty conditions and reports the position correctly. Some treaty positions require extra disclosure or documentation.
State Filing Rules Do Not Follow Form 1040-NR Exactly
Federal nonresident alien status and state residency status are different concepts. A person may need to review both sets of rules for the same year.
A Practical Review Checklist
Before deciding whether Form 1040-NR may be relevant, a reader can gather basic facts and documents. This checklist is for organization only, not a filing decision.
- Confirm federal tax residency for the tax year using the green card test, substantial presence test, and any relevant exceptions.
- List all U.S.-source income received during the year, including wages, scholarship income, dividends, rents, royalties, business income, and partnership income.
- Collect tax forms such as W-2, 1042-S, 1099, Schedule K-1, or school payroll statements.
- Check whether any U.S. federal tax was withheld and whether the withholding matches the income type.
- Review whether Form 8843 applies because of exempt individual day treatment.
- Review whether a tax treaty position is being claimed and whether extra disclosure may be needed.
- Check whether an SSN or ITIN is needed for federal tax filing. The IRS explains ITIN use on its Form W-7 page.
- Review state-source income and state residency rules separately from the federal Form 1040-NR question.

FAQ About Who Files Form 1040-NR
Does every nonresident alien file Form 1040-NR?
No. A nonresident alien generally looks at whether they have a federal filing requirement, taxable U.S.-source income, a refund claim, a treaty position, or another Form 1040-NR filing trigger for the tax year.
Do international students with no income file Form 1040-NR?
Many nonresident students with no income subject to U.S. tax do not file Form 1040-NR, but they may still need to file Form 8843 if they are claiming exempt individual treatment for days of presence. The official Form 8843 instructions should be checked.
Can a nonresident alien file Form 1040 instead of Form 1040-NR?
Generally, Form 1040 is for U.S. citizens and resident aliens, while Form 1040-NR is for nonresident aliens. Some special elections or dual-status situations can change the analysis, so the official instructions and Publication 519 should be reviewed.
Is Form 1040-NR needed if all tax was already withheld?
Sometimes yes, sometimes no. If withholding fully satisfied the tax and no other filing rule applies, the answer may differ from a case where a person owes more tax or wants to claim a refund. The income type and official instructions matter.
Does receiving Form 1042-S always mean Form 1040-NR must be filed?
Not always. Form 1042-S is an information form for certain payments to foreign persons. Whether Form 1040-NR is required depends on the income, withholding, treaty position, and the filer’s overall tax situation.
Does Form 1040-NR cover state nonresident tax?
No. Form 1040-NR is a federal return. State nonresident or part-year resident tax filing is handled under state law and state tax agency instructions.
