The short version
If there is one U.S. tax form Brazilian students forget, it is Form 8843. The reason is simple: it does not feel like taxes. You file it even if you earned nothing, even if you owe nothing, and even if you never file a tax return. It is not a return at all. It is a short statement that records why your days in the country do not count toward becoming a U.S. tax resident. For a student with no income there is usually no money at stake, and no separate late-filing penalty for Form 8843 itself is identified here, which is exactly why it gets skipped. But it is part of the record that supports your nonresident status, and a missing year is a hole in that record you may have to reconstruct later. It is one of the forms international students most often overlook, and this article is how to make sure you do not. Brazil also has no U.S. income tax treaty, so there are fewer simplifying exceptions elsewhere in your filing, which makes getting the baseline forms exactly right matter even more.
(This piece is for F-1 and J-1 students. J-1 scholars, teachers, trainees, and researchers are exempt individuals too, but under different year limits and different parts of the form, so their details are not the same as what follows.)
What the law actually says (primary authority first)
A Brazilian student on an F-1 visa is usually a nonresident alien for the first five calendar years, because the law treats a student as an “exempt individual” under Internal Revenue Code section 7701(b)(5). The label is narrower than it sounds: “exempt individual” does not mean exempt from U.S. tax. It means your days are exempt from counting toward the substantial presence test, the day-count that otherwise turns a foreigner into a U.S. resident for tax. Being an exempt individual is what lets you exclude those days.
Form 8843 is the required statement you file to document and support that claim. The Treasury regulation, Treas. Reg. section 301.7701(b)-8, sets the procedure: an exempt individual claims the day-exclusion by filing the statement, and that statement is Form 8843. Your status still turns on the underlying facts, your visa and your days, not on the paper alone; the form is how you record and support it. The IRS tells every exempt individual to file it, in Publication 519, U.S. Tax Guide for Aliens and on its Foreign Students and Scholars page, even in a year with no income.
What happens if you do not file is more measured than a lot of online advice suggests. For a student with no income there is no tax due, and no separate late-filing penalty for Form 8843 itself is identified here; the regulation’s loss-of-exclusion rule does not list the student statement among the filings it applies to. The cost is to your record. Form 8843 is part of the record that supports your excluded days, so a year without it leaves that position harder to prove. If your residency is ever questioned or your return is examined, a missing statement is a gap you have to reconstruct rather than simply point to. File the form and the gap never opens.
How it works in practice
Who files. Every exempt individual files Form 8843, titled “Statement for Exempt Individuals and Individuals With a Medical Condition.” That means you, and it also means your dependents: a spouse or child here on F-2 or J-2 status generally each files a separate Form 8843, even with no income, as long as they are nonresidents for tax purposes. One form per person, not one per family.
What you fill in. A student completes Part I (your general and visa information, including your visa type and the dates you were present) and Part III (the part for students). Parts II, IV, and V are for teachers and trainees and for medical-condition claims, not for a typical student. The form asks which days you are excluding and under what status, which is the whole point: it is your written claim to exempt-individual treatment.
When it is due. The deadline tracks your Form 1040-NR due date, and that date turns on whether you had wages subject to U.S. withholding, not simply on whether you had income. If you had wages subject to withholding and are filing Form 1040-NR, both are due by April 15. If you are filing Form 1040-NR but had no wages subject to withholding, for example your only U.S. income was a taxable scholarship, the due date is generally June 15. And if you had no income and no return is required at all, Form 8843 goes in by itself, also by June 15. If the Form 1040-NR due date is extended, the standalone Form 8843 deadline moves with it.
How to file it alone. When Form 8843 stands on its own, it is a paper filing: mail it to the Department of the Treasury, Internal Revenue Service Center, Austin, TX 73301-0215, the address the current Form 8843 instructions give for a filer with no return, and confirm it in the instructions before you mail. It is not part of an e-filed return.
If you missed a past year. File the missed form promptly and keep proof that you filed it. Because there is no separate late-filing penalty for the form itself for a no-income student, catching up is low-risk and worth doing. If a missed year could affect your residency position, for example it overlaps the move from nonresident to resident, get it looked at before you file.
The numbers
Every figure here is a rule, not an estimate, and each cites the controlling authority.
| Item | Rule for an F-1 Brazilian student | Source |
|---|---|---|
| Who must file Form 8843 | Each exempt individual: F-1 and J-1 students and their F-2/J-2 dependents, even with no income | Pub 519; Form 8843 instructions |
| Which parts a student completes | Part I and Part III | Form 8843 instructions |
| Deadline, Form 1040-NR with wages subject to withholding | Generally April 15 | Pub 519 (Ch. 7) |
| Deadline, Form 1040-NR without wage withholding, or Form 8843 by itself | Generally June 15 | Pub 519 (Ch. 7); Form 8843 instructions |
| Exempt-individual window for students | Up to 5 calendar years | IRC 7701(b)(5) |
| Penalty for a no-income student who does not file | No separate late-filing penalty for Form 8843 itself identified; main risk is a weaker residency record | Pub 519; Treas. Reg. 301.7701(b)-8 |
| Claiming the exclusion | Form 8843 is the required statement used to document and support the day-exclusion claim | Treas. Reg. 301.7701(b)-8 |
What this means for you
- File Form 8843 every year you are an exempt individual, including a year you earned nothing. It is the cheapest insurance in your U.S. tax life.
- File one for each F-2 or J-2 dependent who is a nonresident, not just for yourself.
- Find your deadline by your wages, not your income: wages with U.S. withholding point to April 15, while a taxable-scholarship-only year or a no-income year is generally June 15.
- If you had income, your Form 8843 rides along with your Form 1040-NR. If you did not, mail it by itself.
- Keep a copy with your I-20, your passport visa stamps, and your record of U.S. entry and exit dates. Together they support the exempt years you are claiming.
- If you skipped it in past years, file the missed forms and keep proof. For a no-income student, no separate late-filing penalty for the form itself is identified here, but if a missed year could affect your residency, get it looked at first.
