If more U.S. tax was withheld from your income than you actually owed, you claim a non-resident tax refund by filing Form 1040-NR for the year the withholding happened. The return reconciles what your employer or payer sent to the IRS against your real liability after tax treaty benefits and any itemized deductions you qualify for, and the balance comes back to you. You generally have three years from the original due date to file and still collect the money.
Why Non-Residents End Up Overpaying
Withholding on non-resident income is built for the worst case, not your case. Employers apply standard federal withholding to wages without knowing whether a tax treaty covers part of your earnings. Banks and brokers apply a flat 30 percent rate to dividends, interest, and other passive U.S.-source income paid to non-residents.1Internal Revenue Service. Taxation of Nonresident Aliens If your country’s treaty with the United States sets a lower rate on that income, or exempts it entirely, the gap between what was withheld and what you owe becomes your refund.
Scholarships, fellowship grants, and pay from teaching or research positions are the classic examples. A payroll system rarely applies treaty exemptions on its own, so the tax comes out at full rate and you reclaim it on the return.
Confirm You’re Filing as a Non-Resident
The IRS treats you as a resident for tax purposes if you held a green card during the year or met the Substantial Presence Test based on days physically in the U.S.2Internal Revenue Service. U.S. Tax Residency – Green Card Test3Internal Revenue Service. Substantial Presence Test Students on F, J, M, or Q visas can exclude their days for up to five calendar years, and teachers and trainees on J or Q visas get two years. To keep that exempt status you must file Form 8843 every year, even with no income.4Internal Revenue Service. About Form 8843, Statement for Exempt Individuals and Individuals with a Medical Condition Residents file a regular Form 1040 instead and follow a different set of rules; the refund process below is for non-residents only.
Documents and ID You Need Before You File
You need a taxpayer identification number on the return. If you’re not eligible for a Social Security Number, apply for an ITIN using Form W-7.5Internal Revenue Service. About Form W-7, Application for IRS Individual Taxpayer Identification Number ITINs expire if unused on a federal return for three consecutive years, so renew a lapsed one before filing or the refund will stall.6Internal Revenue Service. It’s Time Again for Folks to Renew Their ITINs – Here Are Some Things to Remember
The income statements you’ll be transferring onto the return:
- Form W-2, which reports wages and the federal, state, and FICA amounts your employer withheld.
- Form 1042-S, which reports income subject to non-resident withholding, including scholarships, fellowship grants, and treaty-exempt compensation.1Internal Revenue Service. Taxation of Nonresident Aliens
- Form 1099 for dividends, interest, and other income from financial institutions.
- Form 8843 for exempt individuals, filed alongside the return (or on its own if you had no income).4Internal Revenue Service. About Form 8843, Statement for Exempt Individuals and Individuals with a Medical Condition
Filling Out Form 1040-NR
Report your effectively connected income on page one. The tax computed against that income, reduced by any treaty benefit you’re claiming, is your actual liability. Subtract the total federal tax already withheld (shown on your W-2 and 1042-S), and the difference is the refund.
Claiming the Treaty Benefit
The United States has income tax treaties with dozens of countries covering wages, scholarships, fellowship grants, dividends, interest, and royalties.7Internal Revenue Service. Federal Income Tax Withholding and Reporting on Other Kinds of U.S. Source Income Paid to Nonresident Aliens Rates and exemptions vary by country and by income type: a student from one treaty country may have a scholarship fully exempt, while a researcher elsewhere may have compensation protected for two or three years. You claim the benefit on the return by reporting the exempt portion in the treaty section and applying the reduced rate to what remains.
Itemized Deductions
Non-residents cannot take the standard deduction. The single exception is students and business apprentices from India, who may qualify under Article 21 of the U.S.-India treaty.8Internal Revenue Service. Nonresident – Figuring Your Tax Everyone else itemizes on Schedule A (Form 1040-NR), and only against income effectively connected to a U.S. trade or business. The categories you can claim:
- State and local income taxes, capped at $10,000 ($5,000 if married filing separately).9Internal Revenue Service. Publication 519, U.S. Tax Guide for Aliens
- Charitable contributions to qualifying U.S. non-profit organizations.
- Casualty and theft losses from a federally declared disaster.
Where and How to Send It
If you e-file, the return travels electronically and clears faster. Paid preparers are required to e-file 1040-NRs in most cases.10Internal Revenue Service. Instructions for Form 1040-NR (2025) Self-filing electronically means using software that supports the 1040-NR, a smaller field than for the standard 1040.
For paper returns without a payment, mail to the IRS processing center in Austin: Department of the Treasury, Internal Revenue Service, Austin, TX 73301-0215. If you’re enclosing a payment, the return goes to the Charlotte, NC processing center instead.11Internal Revenue Service.

Deadlines and the Three-Year Window
The current-year deadline depends on your income. If you received wages subject to U.S. income tax withholding, your return is due April 15 of the following year. If you had no such wages (scholarship income or investment income only, for example), the deadline is June 15.10Internal Revenue Service. Instructions for Form 1040-NR (2025)
If you’re only owed a refund, there’s no late-filing penalty because there’s no tax due. But you cannot wait indefinitely. You generally have three years from the return’s original due date, or two years from the date you paid the tax, whichever is later, to claim the refund. Withholding during the year counts as paid on the return’s due date for this calculation.12Internal Revenue Service. Time You Can Claim a Credit or Refund After that, the money stays with the Treasury. If you worked in the U.S. a few years back and never filed, check the calendar before assuming it’s too late; if you’re within the window, file.
FICA Refunds Are a Separate Process
Non-residents on F, J, or M visas are generally exempt from Social Security and Medicare taxes, but employer payroll systems sometimes withhold FICA anyway when they miss the visa status.13Internal Revenue Service. Foreign Student Liability for Social Security and Medicare Taxes Don’t expect this money to show up on your 1040-NR. It doesn’t.
Ask your employer first. If they won’t reimburse you or adjust the withholding, file Form 843 (Claim for Refund and Request for Abatement) along with Form 8316.13Internal Revenue Service. Foreign Student Liability for Social Security and Medicare Taxes14Internal Revenue Service. Instructions for Form 843 Attach a copy of your W-2 (FICA amounts appear in Boxes 4 and 6), the passport page showing your visa stamp, your I-94, and your I-20 if you were on CPT or OPT.
After You File
E-filed returns are processed in roughly three weeks; paper returns take six weeks or more from the date the IRS receives them. Non-resident returns sometimes run longer when a treaty claim needs manual review. Track the return with the IRS “Where’s My Refund?” tool using your SSN or ITIN, filing status, and exact refund amount.15Internal Revenue Service. Refunds
Refunds come as a paper check to the address on your return or by direct deposit to a U.S. bank account. If you’ve already left the country and closed your U.S. account, the paper check is the fallback, and international mail adds to the wait.
State Taxes Are Separate
The federal refund is only part of the picture. If you worked in a state with an income tax and it withheld from your paycheck, you likely have a state return to file as well, with its own form, threshold, and deadline. State rules vary widely: some require a non-resident return after a single day of work in the state, others set higher income or day thresholds. A state refund follows the same logic as the federal one, but you claim it through the state’s own tax agency, not the IRS.
