You’ve earned money on a J-1 visa in the U.S., and now tax season is here. You’ve heard you need to file Form 1040-NR instead of the standard 1040 most Americans use. Form 1040-NR is the official tax return form the IRS requires nonresident aliens to file. It works differently than a regular return — it has separate lines for different kinds of income, treats some deductions differently, and asks questions about your residency status. If you’re a J-1 worker with W-2 income (wages from a U.S. employer), understanding what goes on this form and why is the foundation of getting your tax filing right.

This article is written for J-1 visa holders who had a W-2 job and worked more than 3 months in the U.S. If that’s not you, some of this may not apply.

What is Form 1040-NR in one sentence?

Form 1040-NR is the tax return nonresident aliens file with the IRS to report income earned in the U.S. and claim refunds or settle any tax owed. Unlike Form 1040 (the standard U.S. return), 1040-NR is designed for people who are not U.S. citizens or permanent residents and do not meet the Substantial Presence Test — a 183-day rule that determines if the IRS treats you as a resident or nonresident for tax purposes. You file 1040-NR on April 15 of the year following the year you earned the income.

Frequently Asked Questions

Do I have to file Form 1040-NR, or can I file Form 1040 instead?

If you are a nonresident alien for tax purposes, the IRS requires you to file Form 1040-NR, not Form 1040. Your visa status (J-1) is the starting point, but your actual filing status depends on whether you meet the Substantial Presence Test — roughly, whether you’ve spent 183 or more days in the U.S. over a rolling three-year period. In most cases, if this is your first year on a J-1 and you worked fewer than 183 days, you are a nonresident and must file 1040-NR. Filing the wrong form can delay your refund or trigger an IRS notice, so verifying your residency status before you file is critical.

What’s the difference between 1040-NR and 1040?

Form 1040-NR is shorter and structured differently than 1040. It reports only income that is “effectively connected” with a U.S. trade or business — typically W-2 wages. Form 1040-NR also does not allow the standard deduction that U.S. residents get; instead, nonresidents must either itemize deductions or claim a smaller itemized amount. Filing status options are also limited — you generally file as single, married filing jointly, or married filing separately, depending on your spouse’s status. Standard deductions, child tax credits, and some other benefits available to residents are not available on 1040-NR, which is why your refund may be smaller even if you earned the same income.

What income do I report on Form 1040-NR?

You report your W-2 wages on Form 1040-NR. This includes all salary, hourly pay, and other compensation your U.S. employer paid you during the tax year. You also report any other “effectively connected income” — money you earned from a U.S. source while on a J-1 visa, such as interest on a U.S. bank account or tips. Investment income (dividends, capital gains) from U.S. sources may also be reported depending on your situation. Income you earned outside the U.S. is generally not reported on 1040-NR unless you have a tax treaty with your home country that requires it — check with a tax preparer if you have overseas income.

Do I file Form 8843 at the same time as 1040-NR?

Yes. Form 8843 is a supplementary form that nonresident aliens file along with 1040-NR to explain their visa status and days in the U.S. It confirms to the IRS that you qualify as a nonresident for tax purposes and documents how many days you spent in the U.S. in the tax year and prior years. If you forget to file Form 8843, the IRS may disallow your nonresident status and recalculate your tax, which could cost you money. Always file 8843 together with 1040-NR; they go hand-in-hand.

Why is my FICA withholding (Social Security and Medicare) sometimes not refunded?

Many J-1 workers on their first visa have FICA taxes (Social Security and Medicare) withheld from their paychecks, even though nonresidents are generally exempt from these taxes. If your employer should have exempted you but didn’t, you can claim a refund on 1040-NR using Form 8288-B or by filing your return and noting the excess withholding. Not all FICA can be refunded — the rules depend on your visa category and whether you have a tax treaty with your home country. This is a common issue, so it’s worth reviewing your W-2 to check whether FICA was withheld when it shouldn’t have been.

What deductions can I claim on 1040-NR?

Nonresidents can claim itemized deductions (such as state and local taxes paid, mortgage interest, and charitable donations) but not the standard deduction. You can also claim a personal exemption (if you do not claim it on another country’s return) and business expenses if you have self-employment income. Some J-1 workers have minimal deductions and end up owing tax because they cannot use the standard deduction available to residents. Ask yourself: Did I pay state income tax, property tax, or make significant charitable donations? If not, itemizing likely won’t help you.

When is the deadline to file Form 1040-NR, and what if I miss it?

Form 1040-NR is due on April 15 of the year following the year you earned income (so for 2025 income, the deadline is April 15, 2026). You can request an automatic extension to October 15, but an extension to file is not an extension to pay — any tax owed is still due April 15, and interest and penalties accrue if you pay late. If you are owed a refund, filing late will delay your refund, but you won’t owe penalties. Filing early — as soon as your W-2 arrives and you have all your documents — is the fastest way to get your money back.

Can I e-file Form 1040-NR, or do I have to mail a paper return?

Many tax preparation platforms and IRS-authorized e-file providers accept 1040-NR, but not all do. If you use a standard tax software, check whether it supports nonresident alien returns before you buy it. Some practitioners still mail 1040-NR on paper because their software doesn’t support electronic filing for nonresidents. E-filing is faster and more reliable than mailing, so if you can e-file, do it — your refund will arrive weeks sooner than if you mail a paper return.
