Form 8843 2026: exempt individuals and the days left out of the US count

"Exempt individual" is a misleading phrase, and the IRS says so itself: the term does not refer to someone exempt from US tax. It refers to someone whose days of presence do not count towards the substantial presence test. So an international student who stays for 4 years can remain a nonresident alien through that time, and still owe tax on US income such as wages. Form 8843 is the statement that supports the exclusion. It is not a tax return and it involves no payment, but it is needed even by people with no income who owe nothing, which is exactly why it gets missed. There are four categories of exempt individual: foreign government-related people on A or G visas, teachers and trainees on J or Q visas, students on F, J, M or Q visas, and professional athletes at a charitable sports event. People kept in the US by a medical condition that arose there use the same form. Each category has its own limits.

Who must file, and who need not

Immediate family of an exempt student or teacher can also be exempt: a spouse, and unmarried children under 21 who live in the household, if their visa derives from yours. The foreign government-related group is the only one the form's instructions leave out of the filing rule. Household staff on A-3 or G-5 visas do not belong to it, and they count all their days.

The time limits: what the calendar-year counting really means

Both limits count calendar years touched, not years of actual study. Any part of a calendar year counts as a year. A student arriving in August 2022 uses up 2022 as a whole year, so 2026 is the fifth. The text then asks whether you have been exempt for any part of more than 5 calendar years. It does not say in so many words whether the current year is part of that count, so the sixth calendar year is a point we do not settle: our check takes the number of earlier exempt years you enter and leaves 5 inside the limit, and the IRS or an adviser should confirm it if that year decides your status. Past the limit, you can still be exempt if you establish that you do not intend to reside permanently in the US and you have substantially complied with your visa. The facts include whether you kept a closer connection to a foreign country and whether you took steps towards permanent residence.

Teachers and trainees have a tighter limit. You are not exempt in a year if you were exempt as a teacher, trainee or student for any part of 2 of the 6 prior calendar years. The exception needs all of the following: exempt for any part of 3 or fewer of the 6 prior years, a foreign employer paying all your compensation this year, presence as a teacher or trainee in any of the prior 6 years, and a foreign employer paying all your compensation in each of those years. A foreign employer can be an office of an American entity in a foreign country or US territory. You must attach information proving it. Publication 519's example is Carla, a J-visa teacher exempt for 2 earlier years. Her employer is foreign this year but was not in those earlier years, so she is not exempt. Had it been foreign throughout, she would be.

Note that the years mix: a student who then becomes a teacher carries those student years into the teacher test. These are the results from the engine that sits behind the check above:

And here is why it matters. Someone present 300 days a year for 3 years, with no excluded days, reaches 450 weighted days and is a resident. The same person, with every day excluded, stands at 0. For the count, an exempt year is a year of zero, and the prior-year fractions fall away too.

Where, and by when, it goes

If you are filing Form 1040-NR, attach Form 8843 to it and mail it to the return's address. If you have no return to file, mail the form on its own to Department of the Treasury, Internal Revenue Service Center, Austin, TX 73301-0215, by the due date for Form 1040-NR, including extensions. In the 2025 edition of Publication 519 that date is April 15, 2026 for people with wages subject to withholding and June 15, 2026 for people without. If filed separately, you must complete all entries. If attached to Form 1040-NR, you can skip lines 1a to 4a if the same information is on your return, and write "Information provided on Form 1040-NR" on line 1a.

What happens if it is late: the IRS's two wordings

This is the one place where the official wording does not line up, and we would rather show you than smooth it over. The IRS's page on the substantial presence test says that if you do not timely file Form 8843, you cannot exclude the days you were present as an exempt individual or because of a medical condition. Publication 519 and the instructions to the 2025 form both describe the consequence for days present as a professional athlete or because of a medical condition, and they do not mention students or teachers in that sentence. The instructions add that failure to exclude days can result in your being considered a US resident.

We do not settle this difference. Our advice is the obvious one: treat the deadline as binding in all categories, since the broader IRS page does not exempt anyone. All three sources give the same way back: showing by clear and convincing evidence that you took reasonable actions to become aware of the filing requirements and significant steps to comply with them.

The medical exception is narrower than it sounds

It covers days you intended to leave but could not because of a medical condition or problem that arose while you were in the US. Whether you intended to leave on a particular day depends on the facts. You cannot exclude any days if you entered or returned for medical treatment, even with unforeseen complications. Nor if the condition existed before you arrived and you knew of it, or if you were initially prevented from leaving, then could leave, but stayed beyond a reasonable period for making arrangements. A physician or other medical official completes line 18.

What exemption does not give you

Excluding days only affects the substantial presence test. It does not cover the green card test: a lawful permanent resident is a resident regardless of days. It does not end US tax on US income. Nor does it decide what another country thinks of you. A student who has used up the limit and fails to show the required intent starts to count days, so the substantial presence test calculator becomes the relevant page, and with fewer than 183 days a year the closer connection exception may help. A separate closer connection route for students exists on the IRS's site, and we have not analysed it here.

The check above uses your status and your exempt years to decide whether this year's days stay out, then runs the 3-year count. It accepts your word on the visa and the employer. Its defaults show a student with 2 exempt years and 200 days this year, days that would otherwise meet the test alone. It does not prepare the form or replace a school's international office. If you switch status, the Taxlag app can hold your dates as the count begins.
