Nonresident Alien Tax Exit: Leaving a US Job

Exit Timing and Refund Clocks

Amended claims and refunds run through the statute of limitations — 3 to 4 years for most treaty claims. Leaving the country does not kill the refund: ITIN + mailing address + direct-deposit arrangements work for foreign addresses. Related: state tax changes for 2026 and the W-2 new year checklist.

Confirm Residency Status Before Your Last Day

Your exit filing turns on one fact: whether you meet the substantial presence test for the calendar year. Run the day count before you leave, not after. The test weighs physical days in the US across the current year plus the two prior years, and days in certain visa categories are excluded from the count. The result decides which form you file, whether a treaty article applies, and which state returns you owe.

• Write down every entry and exit date from your passport record and your I-94 history before you hand in notice.
• Count all days in the current year, one-third of the prior year, and one-tenth of the year before that.
• Check your visa category for exempt-person days. Student, teacher, researcher, and trainee periods follow different rules than employees on a work petition.
• Keep the day count with your final pay statements. An IRS notice that questions residency is answered with dates, not memory.
• Ask payroll for the correct name and address on the Form W-2 before systems access ends. A wrong address delays the refund more than a wrong deduction does.

Build The Treaty File While You Still Have Access

Treaty relief is claimed with facts, and most of those facts live in your employer records. Collect them in your last week.

• Get the payer name and EIN from the W-2. Treaty articles turn on who paid the wages, and a staffing agency or subsidiary entity changes the analysis.
• Save every pay statement for the year, including a final check or severance payment that lands in the next year.
• Keep the offer letter, petition copies, and the date of each status change.
• Note the country of tax residence and the article you intend to claim, with the day count for each article.
• Claim treaty benefits even when the W-2 shows full withholding. Withholding is not a determination of your treaty rights, and refunds are common.

Some treaty articles changed in recent years. Confirm the current article text on the IRS treaty page before you file, and attach the required disclosure statement. Send the written request for payroll documents with the final paycheck demand letter so the ask sits on one dated record.

State Exit Filings And The Refund Clock

State tax follows where you worked, not where you land. A mid-year departure usually creates a part-year or nonresident filing duty in the state that employed you.

• File a part-year resident return where required, and confirm the income allocation method with that state revenue department.
• Nonresidents who worked in a state file a nonresident return for those wages even after departure.
• Keep your ITIN or SSN active. An inactive ITIN blocks electronic filing and stalls the refund.
• Give the IRS a mailing address that still receives mail after departure, and confirm whether direct deposit from a foreign account is available before you count on it.

File the original return on time, then amend once the treaty file is complete. Amended claims stay open inside the statute of limitations, so a missed treaty claim in year one is usually still recoverable. Check the final-pay window on the California final paycheck page if California employed you, since the last check often lands in a different tax year than the job.

Cross-check the definition and the generator with the equity tax trails guide hub. Confirm there before you put a date or a dollar amount in writing.

Frequently Asked Questions

Do I still file a US return after leaving the country?

Yes, if you earned US-source wages during the year. The filing duty follows the income, not your address. Nonresidents file Form 1040-NR, and residents file the standard return for the period they were treated as resident.

Which filing deadline applies to a departing foreign worker?

Nonresidents who are not living in the US on the normal due date generally use the later deadline described in the form instructions. If you keep a US address on the filing date, use the standard deadline and confirm it before you file.

Can a treaty exemption reduce tax on my severance?

It can, depending on the article and on who paid it. Severance from a former employer is often treated as wages. Confirm the article text and the payer identity in writing before you claim the exemption on the return.

What happens to my refund if my address is abroad?

Refunds can be sent to foreign addresses, though direct deposit from a foreign account is not always available. Keep your ITIN active, provide an address that receives mail, and follow up if nothing arrives within the processing window.

Treaty exemptions, the part-year filing lines, and the refund window are federal and state tax rules, with the state side graded in this build from reported sources. Confirm the part-year filing question with the state tax agency named on the state rule pages, confirm the treaty article with IRS guidance, and keep the W-2, the ITIN active, and the mailing address in one file so the refund path survives a foreign address. Re-check withholding before you leave with the offer acceptance email generator, and keep the W-4 record in the same file as the treaty claim.
