Form 8843 is an IRS statement used by certain alien individuals to explain why days physically present in the United States are excluded when applying the substantial presence test. For international students and scholars, it most often appears when F, J, M, or Q status creates a period in which the person is treated as an exempt individual for day-counting purposes.
The term can be misleading. An exempt individual is not automatically exempt from U.S. income tax. Form 8843 does not calculate taxable income, determine a refund, or replace an income tax return. Its main role is to document the basis for excluding certain U.S. presence days from the federal tax residency calculation.
The line references below follow the 2025 Form 8843, which is the current final revision linked from the IRS Form 8843 page. Year labels on later versions can change, so the form for the tax year being filed controls.
Students and Scholars Do Not Use the Same Part of Form 8843
Form 8843 does not contain a separate category called “scholar.” Instead, the IRS divides the relevant nonimmigrant categories into students and teachers or trainees. This distinction determines which section of the form applies.
| U.S. status or role | Form 8843 category | Relevant section |
|---|---|---|
| F-1 student | Student | Part I and Part III |
| J-1 student | Student | Part I and Part III |
| M student | Student | Part I and Part III |
| Q participant whose qualifying role is as a student | Student | Part I and the applicable Part III lines |
| J-1 professor, research scholar, teacher, or other nonstudent exchange visitor | Teacher or trainee for Form 8843 purposes | Part I and Part II |
| Q teacher or trainee | Teacher or trainee | Part I and the applicable Part II lines |
The Form 8843 instructions define a teacher or trainee as a person temporarily present under a J or Q visa, other than as a student, who substantially complies with the requirements of that status. As a result, a university title such as “research scholar” does not create a separate Form 8843 category. A nonstudent J-1 research scholar or professor generally falls within the teacher-or-trainee rules used by the form.
“Exempt Individual” Refers to the Substantial Presence Test
Federal tax residency can be affected by the number of days a non-U.S. citizen is physically present in the United States. The substantial presence test normally uses the current year’s days plus weighted portions of days from the two preceding years.
Qualifying days spent as an exempt individual are not counted for that test. The student category can include people temporarily present under F, J, M, or Q status for the primary purpose of studying. The teacher-or-trainee category generally applies to qualifying J or Q nonstudents.
Exempt individual does not mean tax-exempt person. The term concerns which days are counted toward the substantial presence test. It does not by itself determine whether wages, scholarships, investment income, treaty benefits, Social Security and Medicare taxes, or other U.S. tax items apply.
Students and Scholars Have Different Calendar-Year Limits
One of the most consequential Form 8843 distinctions is that the student rule and the teacher-or-trainee rule use different calendar-year tests. These rules look at calendar years, not simply the number of months spent in the United States.
Students: The More-Than-Five-Calendar-Years Rule
Under the IRS student rule, a person generally stops receiving the normal student exempt-individual treatment after having been exempt as a teacher, trainee, student, exchange visitor, or cultural exchange visitor under F, J, M, or Q status for any part of more than five calendar years. The five years do not have to be five uninterrupted 12-month periods.
A partial year can count. For example, if qualifying student exempt-individual treatment begins near the end of December, that December can still fall within one of the calendar years considered under the rule. Counting only anniversaries of the U.S. arrival date can therefore produce a different result from counting calendar years.
Passing the five-calendar-year point does not create an automatic rule that every later U.S. day must be counted. IRS rules allow a student beyond that period to establish that there is no intent to reside permanently in the United States and that the requirements of the nonimmigrant status have been substantially complied with. The IRS considers facts and circumstances, including a closer connection to a foreign country and affirmative steps toward lawful permanent resident status.
This is why Part III asks both whether the person has been exempt for more than five calendar years and whether steps were taken toward lawful permanent resident status.
Teachers and Scholars: The Two-of-Six Lookback
The teacher-or-trainee category works differently. A qualifying J or Q nonstudent generally cannot exclude days as a teacher or trainee for a current year if that person was exempt as a teacher, trainee, or student for any part of two of the six calendar years preceding the current year.
Earlier student years count in this lookback. A person who later arrives as a J-1 research scholar cannot determine the result solely from the start date on the newest DS-2019. Earlier F-1 or J-1 periods can change the answer.
Why an Earlier F-1 Period Can Affect a Later J-1 Scholar Period
Consider a person analyzing the 2025 tax year who was an exempt F-1 student during 2020 and 2021, then spent several years outside the United States before returning as a J-1 research scholar in 2025. Part II looks back to the six calendar years preceding 2025: 2019 through 2024. The two earlier F-1 years remain inside that window.
That history is relevant even though the current program is a research-scholar program rather than a student program. Line 8 of the 2025 Form 8843 specifically asks whether the person was exempt as a teacher, trainee, or student for any part of two of those six preceding years.
The IRS provides a narrower exception to the teacher-or-trainee limitation when all of the required foreign-employer conditions are met. Under the current IRS rule, the person must have been exempt for part of three or fewer of the preceding six years, a foreign employer must pay all compensation for the current year, the person must have been present as a teacher or trainee in at least one of the six preceding years, and a foreign employer must have paid all compensation during each of those prior teacher-or-trainee years. This exception is fact-dependent and is not the ordinary two-of-six rule.
Part I: What the General Information Lines Are Asking
Part I records identity, immigration history, passport information, and U.S. presence days. The distinction between actual presence and excluded days is especially useful to understand before entering numbers on line 4.
Name, TIN, and Address Fields
The heading requests the person’s name and U.S. taxpayer identification number “if any.” Form 8843 therefore does not instruct a person without an SSN or ITIN to invent or substitute another identification number.
The country-of-residence and U.S. address boxes carry another easily missed instruction: those addresses are completed when Form 8843 is being filed by itself rather than with a U.S. tax return.
Line 1a: Visa Type and Most Recent U.S. Entry
Line 1a asks for the nonimmigrant visa type and the corresponding date of the most recent entry to the United States. The IRS instructions direct filers to the electronic CBP I-94 arrival/departure record for this information.
The visa issuance date and the most recent U.S. entry date are not necessarily the same date. A person who has traveled outside the United States and returned may have a recent I-94 entry that is much later than the date the visa was issued.
Line 1b: A Status Change Inside the United States
Line 1b matters when nonimmigrant status changed after the last U.S. entry without a departure and reentry. The form asks for the current nonimmigrant status and, when the status changed while the person was in the United States, the change date and previous status.
The Form 8843 instructions refer to Form I-797, Notice of Action, as a place to identify the approved change-of-status date. This is different from simply receiving a new visa abroad and later entering the United States with it.
Lines 2 and 3: Citizenship and Passport Information
Line 2 asks for the country or countries of citizenship during the tax year. Line 3 separately asks which country or countries issued the passport and requests the passport number or numbers. Citizenship and passport issuance are separate questions, which can matter for a dual citizen or someone who has held more than one passport.
Lines 4a and 4b: Actual Presence Versus Excluded Days
Line 4a asks for the actual number of days present in the United States during the three years shown on the form. On the 2025 version, those years are 2025, 2024, and 2023. Line 4b then asks for the number of current-year days claimed as excludable for substantial-presence-test purposes.
Those two entries answer different questions. Exempt-individual days do not disappear from the factual record of physical presence simply because they may later be excluded from the substantial presence calculation.
| Presence information | Days |
|---|---|
| Actual U.S. presence during the tax year | 350 |
| Days that meet the applicable exempt-individual requirements | 350 |
| Line 4a current-year entry | 350 |
| Line 4b excluded-day claim | 350 |
The numbers will not always match. A status change during the year, a period outside the qualifying category, or another day-counting issue can cause actual presence and excluded days to differ. Travel records and immigration-status dates therefore matter more than simply estimating the number of months spent in the country.
Part III for F, J, M, and Q Students
A person treated as a student under the Form 8843 rules completes Part III in addition to the applicable general information. The section combines current school information with prior visa history and the five-calendar-year test.
Lines 9 and 10: School and Program Information
Line 9 asks for the name, address, and telephone number of the academic institution attended during the tax year. Line 10 asks for the name, address, and telephone number of the director of the academic or other specialized program in which the person participated.
For a Q student, the form instructions are more specific: Part I and lines 10 through 14 of Part III are used, and line 10 identifies the director of the cultural exchange program.
Line 11: Prior Visa History
Line 11 reconstructs the prior six calendar years of F, J, M, or Q visa history. On the 2025 form, the listed years are 2019 through 2024. If the visa type changed during one of those years, the form instructs the filer to attach a statement identifying the new visa type and the date it was acquired.
Old I-20s, DS-2019s, I-94 records, passports, and earlier Forms 8843 can be useful here. Looking only at the current immigration document can miss a prior calendar year that affects line 12.
Line 12: More Than Five Calendar Years
Line 12 asks whether the person was exempt as a teacher, trainee, or student for any part of more than five calendar years. A “Yes” answer does more than record elapsed time. The 2025 form states that sufficient facts must be provided in an attached statement to establish that the person does not intend to reside permanently in the United States.
Lines 13 and 14: Steps Toward Lawful Permanent Residence
Line 13 asks whether, during the tax year, the person applied or took other affirmative steps to apply for lawful permanent resident status, or had a pending application to change status to lawful permanent resident. Line 14 provides space for an explanation when line 13 is answered “Yes.”
These questions connect directly to the facts-and-circumstances analysis used when student exempt-individual treatment extends beyond the ordinary five-calendar-year period. Immigration classification and federal tax residency remain different legal concepts, but immigration history can provide facts used in the federal tax residency analysis.
Part II for J-1 Scholars, Professors, Teachers, and Trainees
Part II applies to qualifying J or Q nonstudents treated as teachers or trainees under the form’s definition. For tax-day-counting purposes, this is where many J-1 research scholars and professors fall even though their university documents may use the word “scholar” rather than “teacher” or “trainee.”
Lines 5 and 6: Institution or Program Information
Line 5 asks teachers for the name, address, and telephone number of the academic institution where they taught during the tax year. Line 6 asks trainees for the name, address, and telephone number of the director of the academic or other specialized program in which they participated.
A person in Q status completes Part I and only lines 6 through 8 of Part II under the current instructions.
Line 7: Six Years of J or Q History
Line 7 lists the six calendar years preceding the tax year and asks for the J or Q visa type held during those years. On the 2025 form, those years are 2019 through 2024. If the visa type changed during one of the listed years, an attached statement identifies the new type and acquisition date.
Line 8: Prior Exempt Years
Line 8 asks whether the person was exempt as a teacher, trainee, or student for any part of two of the preceding six calendar years. This is broader than asking whether the person previously held J-1 research-scholar status. An earlier exempt F-1 student year can be part of the same lookback.
The form states that a “Yes” answer generally prevents exclusion of current-year days as a teacher or trainee unless the foreign-employer exception in the instructions applies. That is why reconstructing earlier status by calendar year is central to Part II.
Documents That Help Reconstruct the Form
Form 8843 often depends on information spread across immigration and travel records rather than one tax document. The records most directly connected with the student and scholar sections include:
- Passport records for citizenship, issuing country, passport number, and travel history.
- CBP I-94 records for the most recent entry date and recorded class of admission.
- Current and prior Forms I-20 for F or M student history.
- Current and prior Forms DS-2019 for J exchange-visitor history and program category.
- Form I-797 when a change of status was approved inside the United States.
- Entry and departure records when line 4 presence days need to be reconstructed.
- Earlier Forms 8843 when identifying calendar years previously treated as exempt-individual years.
- School or program contact information for the institutional entries in Part II or Part III.
Forms W-2 and 1042-S can be relevant to the separate question of whether an income tax return is required, but they are not the records that establish the visa history and calendar-year information requested by Form 8843 itself.
Filing Form 8843 With Form 1040-NR
When a 2025 Form 1040-NR is being filed, the Form 8843 instructions say to attach Form 8843 to that return rather than mail it separately.
There is also a useful completion rule for attached forms. If the information requested on Form 8843 lines 1a through 4a has already been provided on the corresponding Form 1040-NR and Schedule OI lines, those Form 8843 lines do not have to be completed again. In that situation, the IRS instructs the filer to enter “Information provided on Form 1040-NR” on line 1a.
That shortcut does not extend through the entire form. Line 4b and the remaining applicable portions of Form 8843 still need to be completed.
Filing Form 8843 by Itself
An international student or scholar can have a Form 8843 filing even when no federal income tax return is otherwise required. IRS international-filer materials specifically include qualifying students and scholars regardless of whether they had income.
When Form 8843 is filed separately, the form instructions require all applicable entries to be completed. The address fields at the top of the form are also completed in the standalone filing situation.
The signature rule changes as well. The signature area on Form 8843 says to sign there only when the form is being filed by itself and not with a U.S. tax return.
For a standalone 2025 Form 8843, the published IRS mailing address is:
Department of the Treasury
Internal Revenue Service Center
Austin, TX 73301-0215
Mailing addresses can change between form revisions, so the instructions for the tax-year version being filed take precedence over an older saved address.
The Filing Date Depends on the Filing Path
Form 8843 does not have one universal calendar date that can be stated without reference to the tax year and filing situation. The standalone form instructions tie its due date to the Form 1040-NR filing rules, including extensions.
| 2025 filing situation | Form 8843 treatment | Published due date |
|---|---|---|
| Form 1040-NR filer who was an employee and received wages subject to U.S. income tax withholding | Attach Form 8843 to Form 1040-NR when applicable | April 15, 2026 |
| Form 1040-NR filer without employee wages subject to U.S. income tax withholding | Attach Form 8843 to Form 1040-NR when applicable | June 15, 2026 |
| Calendar-year individual filing Form 8843 alone because no 2025 income tax return is required | File Form 8843 separately | Generally June 15, 2026 |
A later tax year has its own dates. The 2025 Form 1040-NR instructions also state that when a due date falls on a Saturday, Sunday, or legal holiday, filing moves to the next business day.
Current IRS materials use somewhat different wording when discussing late Form 8843 filings. The IRS substantial-presence page broadly warns that untimely filing can affect the ability to exclude exempt-individual days, subject to a compliance-related exception, while the penalty paragraph printed in the 2025 Form 8843 instructions is narrower in the categories it expressly names. This does not support treating a late student or scholar Form 8843 as carrying a simple fixed-dollar penalty or as having no possible consequence. The tax-year instructions and current IRS guidance both matter when a filing is late.
F-2 and J-2 Family Members Are Evaluated Individually
The exempt-individual rules can extend to certain immediate family members whose nonimmigrant status is derived from and dependent on the principal student’s or teacher’s status. For this purpose, IRS guidance includes a spouse and qualifying unmarried children. An unmarried child must be under age 21, regularly reside in the exempt individual’s household, and not be a member of another household.
The federal tax residence test is applied separately to each person. IRS international-filer training materials specifically identify family members in F-2 or J-2 status when discussing separate Form 8843 obligations. A principal F-1 or J-1 person’s Form 8843 is therefore not a combined family filing that automatically records the spouse’s or child’s excluded days.
A December Arrival Can Use a Calendar Year
The student and teacher-or-trainee limitations repeatedly use the phrase calendar year. That is why a short period at the end of a year can matter. If exempt-individual treatment applies during a December arrival, that calendar year can enter the historical count even though the person was present for only a small part of the year.
This issue becomes easier to miss after several years of travel, program changes, or time outside the United States. Counting “years since first arrival” is not always a substitute for reconstructing the actual F, J, M, or Q history year by year.
Changing Status During the Year Can Make Lines 4a and 4b Different
A person can be physically present for an entire period while only part of that period falls within a qualifying exempt-individual category. A change from one nonimmigrant status to another can therefore affect both line 1b and the number of days reported as excluded on line 4b.
The actual U.S. presence record and the exempt-day analysis should not be collapsed into one number before the immigration-status dates are identified. The same issue can arise when a person makes several trips abroad during the year: line 4 depends on days, not merely on the start and end dates of an academic program.
Form 8843 Does Not Decide Every Nonresident Tax Question
Form 8843 addresses excluded presence days and the basis for that exclusion. It does not, by itself, determine the amount of taxable income, eligibility for a treaty benefit, whether Form 1040-NR is otherwise required, whether a particular scholarship is taxable, whether Social Security and Medicare taxes apply, or whether a state treats a person as a resident.
It also does not make immigration status and federal tax residency interchangeable. F-1 or J-1 classification describes immigration status; resident-alien or nonresident-alien treatment for federal income tax purposes is determined under federal tax residency rules. Form 8843 is one part of that tax-residency analysis when qualifying days are excluded.
