Form 8843 Explained: Who Must File, How to Complete It and the Deadline

If you were in the United States on an F, J, M or Q visa as a student, or on a J or Q visa as a teacher, researcher or trainee, you generally must file Form 8843 for every year you were present and excluding those days from the substantial presence test. You file it even if you had no U.S. income at all. Your spouse and dependents on F-2 or J-2 status file their own Form 8843 too. If you also have to file a nonresident return, you attach Form 8843 to Form 1040-NR; if not, you mail it on its own.

What is Form 8843 and why does it exist?

The IRS decides whether a non-citizen is a U.S. tax resident mainly through the substantial presence test, which counts days spent in the country. Someone in the United States for an entire academic year would normally pass that test and be taxed like a resident on worldwide income. The tax code carves out "exempt individuals" — mainly students, teachers and trainees — whose days do not count. Form 8843, "Statement for Exempt Individuals and Individuals With a Medical Condition," is how you tell the IRS you are one of them. It is not a tax return and it does not calculate tax. It is a statement that protects your nonresident status.

Who must file Form 8843?

• Students on F-1, J-1, M-1 or Q-1 visas who are within their exempt-year limit.
• Teachers, researchers and trainees on J or Q visas (other than students) within their exempt-year limit.
• Dependents in F-2, J-2, M-2 or Q-3 status — each person files a separate form, including children.
• People who could not leave the United States because of a medical condition that arose while they were here.
• Certain professional athletes competing in qualifying charitable sports events.

Most foreign government-related individuals on A or G visas (other than A-3 and G-5) are exempt from the day count but are not required to file Form 8843.

How many years can you be exempt?

Students are generally exempt for days in any part of five calendar years. The years do not need to be consecutive, and a partial year counts as a full year. After the fifth year, a student can remain exempt only by showing the IRS they do not intend to live permanently in the United States and have complied with their visa terms. Teachers and trainees are generally not exempt if they were exempt as a teacher, trainee or student for any part of two of the previous six calendar years. Counting these years correctly is the single most important step, because it decides whether you file as a nonresident at all.

Do I need to file Form 8843 if I had no income?

Yes. This is the most common question we hear from international students. Form 8843 is about your days of presence, not your income. A student who arrived in August, lived on family savings and never worked still files Form 8843 for that year. There is no monetary penalty printed on the form, but without it you may lose the ability to exclude your days — which can make you a U.S. tax resident for the year on paper, with worldwide income reporting and possibly foreign account reporting that you never intended to trigger.

How to fill out Form 8843, part by part

The form is two pages. Everyone completes Part I, and then only the part that matches your situation.

• Part I (General information): your name, U.S. taxpayer identification number if you have one, visa type and date of entry, current nonimmigrant status, country of citizenship and passport details, and the number of days you were present in each of the last three years. If you have no SSN or ITIN, leave the number blank — you do not need to apply for one just to file Form 8843.
• Part II (Teachers and trainees): the academic institution or program sponsor, its address and phone number, and the years you held J or Q status.
• Part III (Students): your school, its director or responsible official, the visa types you held in prior years and whether you applied for permanent residence. Answer the questions about prior years carefully; they drive the five-year count.
• The remaining parts cover professional athletes and individuals with a medical condition, with supporting documentation such as a physician's statement.

Sign and date the form. Each family member signs their own; a parent or guardian signs for a minor child.

Form 8843 deadline and where to send it

• If you had U.S. wages subject to withholding (for example, on-campus work or OPT): attach Form 8843 to Form 1040-NR, generally due April 15.
• If you had no income that requires a return: file Form 8843 by itself by June 15 of the following year.
• A standalone Form 8843 is generally mailed on paper to the IRS address listed in the current form instructions (currently in Austin, Texas). Keep a copy and proof of mailing.

Form 8843 and Form 1040-NR: how they fit together

Form 8843 establishes that you are a nonresident. Form 1040-NR reports any U.S.-source income you had as a nonresident — wages, a taxable scholarship, a fellowship stipend, or certain investment income. Many students also qualify for a treaty benefit on wages or scholarships, claimed on the 1040-NR and, for wages, with Form 8233 given to the employer. Nonresident students generally cannot use the standard deduction (students from India are a notable treaty exception) and cannot file jointly with a spouse.

Common Form 8843 mistakes

• Filing a regular Form 1040 through consumer tax software instead of a 1040-NR. This often claims credits a nonresident cannot take and later requires an amended return.
• Forgetting the F-2 or J-2 spouse and children, who need their own forms.
• Miscounting exempt years — counting only full years, or restarting the count after a change of school.
• Assuming that no income means nothing to file.
• Paying Social Security and Medicare taxes on student wages that may be exempt for nonresident F-1 and J-1 students. If they were withheld in error, ask the employer for a refund first.
• Continuing to file as a nonresident after the exemption ended, for example after moving to H-1B status mid-year, which may require a dual-status return.

What changes when you switch to H-1B or a green card?

Once you are no longer an exempt individual, your days start counting toward the substantial presence test from the date your status changes. Many people who move from F-1 or OPT to H-1B become residents during that year or the next, and may need a dual-status return for the transition year. The change also brings foreign bank account (FBAR) and foreign asset reporting into play for the first time, which is where former students most often fall behind.
