Form 8843 is the IRS Statement for Exempt Individuals and Individuals with a Medical Condition, filed by certain visa holders and by people stranded in the country by illness to exclude their days of U.S. presence from the Substantial Presence Test.1Cornell Law School. U.S. 26 CFR § 301.7701(b)-8 Excluding those days can keep you classified as a nonresident alien, who is generally taxed only on U.S.-source income, rather than as a resident alien taxed on worldwide income.2IRS. Alien Taxation – Certain Essential Concepts You have to file the form even if you earned nothing during the year. Without it, the IRS can count every one of those days toward residency.3IRS.

Who Needs to File Form 8843
Being an “exempt individual” for the Substantial Presence Test means your days here don’t count toward tax residency. It does not mean you owe no U.S. tax on U.S.-source income.4IRS. Substantial Presence Test You need to file Form 8843 if you want to claim that exclusion and you fall into one of these groups:5IRS. Foreign Students and Scholars – Form 8843: Parts I through V
- Students on F, J, M, or Q visas in substantial compliance with visa requirements.
- Teachers and trainees on J or Q visas in substantial compliance.
- Professional athletes temporarily in the country for a charitable sports event.
- Spouses and unmarried children under 21 on derivative visas such as F-2 or J-2.
The exemption has a shelf life. Students generally can’t exclude days once they’ve been exempt as a student, teacher, or trainee for any part of more than five calendar years, unless they can show they don’t intend to reside permanently in the U.S.6IRS. Exempt Individual – Student Teachers and trainees are generally limited to excluding days if they weren’t exempt for any part of two of the six preceding years.7IRS. Exempt Individuals – Teachers and Trainees
Form 8843 also covers a separate situation: someone who meant to leave the country but couldn’t because of a medical condition that arose while they were already here. The condition has to have developed after arrival. If it existed before you arrived and you knew about it, or if you stay longer than needed once you’re well enough to travel, those days may not qualify.8Cornell Law School. 26 CFR § 301.7701(b)-3
What the Form Asks For
You’ll need your entry and exit dates for the current year and the two years before it, because the Substantial Presence Test counts days across a three-year window. Passports help, but the real requirement is keeping accurate personal travel records.4IRS. Substantial Presence Test
The form has five parts. Everyone completes Part I with biographical information. Teachers and trainees fill out Part II, students Part III, professional athletes Part IV, and people claiming a medical condition Part V.5IRS.

How and When to File
How you submit Form 8843 depends on whether you also owe a tax return. If you’re required to file Form 1040-NR, attach Form 8843 to it.4IRS. Substantial Presence Test If you don’t have to file a return, sign and date the form and mail it on its own to the Department of the Treasury, Internal Revenue Service Center, Austin, TX 73301-0215.7IRS. Exempt Individuals – Teachers and Trainees For a child who can’t sign, a parent or guardian signs the child’s name followed by “By [parent’s signature], parent for minor child.”5IRS. Foreign Students and Scholars – Form 8843: Parts I through V
The deadline tracks the nonresident tax return due date. If you received wages subject to U.S. withholding, that’s typically April 15. For many other nonresidents, it’s June 15. Check the current year’s instructions for your specific date.9IRS. Taxation of Nonresident Aliens
The IRS usually doesn’t send a receipt. Keep a signed photocopy and proof of mailing for your records in case of a later audit. If the agency finds a problem, it typically writes to the address on the form.
What Happens If You Don’t File
Skipping a required Form 8843 lets the IRS count every day of your U.S. presence toward the Substantial Presence Test, which can flip you into resident alien status and expose your worldwide income to U.S. tax. There is a narrow exception: if you can show you took reasonable steps to learn the rules and made a significant effort to comply, the IRS has discretion to accept a late filing.10Cornell Law School. 26 CFR § 301.7701(b)-8
Other Ways to Stay a Nonresident
Form 8843 isn’t the only path. If you actually meet the Substantial Presence Test but keep stronger ties to another country, you may qualify to file Form 8840 and be treated as a nonresident under the “closer connection” exception.4IRS. Substantial Presence Test A tax treaty between the U.S. and your home country can also help. If you’re a resident of both countries under each country’s rules, treaty tie-breaker provisions may let you claim U.S. nonresident status, generally disclosed to the IRS on Form 8833.
