For many F-1 students, Form 8843 is the IRS statement that explains why certain days physically spent in the United States are excluded when applying the substantial presence test. It is not an income tax return, and filing it does not by itself report wages, scholarships, tax due, or a refund.
An F-1 student who claims excluded days under the student “exempt individual” rules generally files Form 8843 for that tax year. The filing can exist even when no Form 1040-NR is otherwise required. The phrase exempt individual is tax-residency terminology: it refers to excluding qualifying days from the substantial presence test, not to a blanket exemption from U.S. tax.
When Form 8843 Applies to an F-1 Student
The filing question starts with tax residency and day-counting rules, not simply with whether a student earned income. IRS rules require a fully completed Form 8843 when a student in F, J, M, or Q status is relying on the student category to exclude U.S. presence days from the substantial presence test.
| Situation | Form 8843 Treatment | Income Tax Return |
|---|---|---|
| F-1 student claims excluded student days and has no federal income tax return filing requirement | Form 8843 is generally filed by itself | Form 1040-NR may not be required solely because Form 8843 is required |
| F-1 student claims excluded student days and files Form 1040-NR | Form 8843 is attached to the return | Form 1040-NR is filed under the rules that apply to the student’s income and tax status |
| F-2 spouse or child also has qualifying exempt-individual days | A separate Form 8843 is prepared for that person | Any income tax return requirement is determined separately |
| Student has already used more than five calendar years as an exempt teacher, trainee, or student | Form 8843 requires additional analysis and, in some cases, an attached statement | Tax residency depends on the applicable residency rules and the student’s facts |
Immigration status and federal tax residency are related but are not the same classification. Holding valid F-1 status does not, by itself, establish that a person is a nonresident alien for federal tax purposes for every year.
What Form 8843 Does to the U.S. Day Count
The substantial presence test normally looks at physical presence over a three-year period. It counts all countable days in the current year, one-third of countable days in the preceding year, and one-sixth of countable days in the second preceding year. A person generally also needs at least 31 days of presence in the current year for the test to be met.
Form 8843 documents why qualifying days are left out of that calculation. This creates an easy distinction that matters throughout the form: days physically present in the United States are not automatically the same as days counted for the substantial presence test.
A student can be physically present in the United States on a day while that day is excluded from the substantial presence test under the student exempt-individual rules.
This is also why the word “exempt” can be misleading. Form 8843 does not make wages, scholarships, investment income, or other income automatically tax-free. It addresses the treatment of days for the substantial presence test.
The Five-Calendar-Year Rule Is Not a 60-Month Rule
For an F-1 student, the usual student exempt-individual limit is measured in calendar years. A partial calendar year can use one of those years. The count is not based on 60 months from the arrival date.
Suppose an F-1 student first enters the United States on December 20, 2022 and is treated as an exempt individual for the remaining days of that year. The calendar-year sequence is 2022 as year 1, 2023 as year 2, 2024 as year 3, 2025 as year 4, and 2026 as year 5. The fact that only a small part of December was spent in the United States does not turn 2022 into a fraction of an exempt calendar year.
Earlier Teacher, Trainee, or Student Years Can Affect the Count
The five-year question is broader than “How many years have I had an F-1 visa?” Form 8843 asks whether the individual was exempt as a teacher, trainee, or student for any part of more than five calendar years. Earlier exempt-individual years in another qualifying classification can therefore matter.
The form’s visa-history line also looks back at prior F, J, M, or Q classifications. A change between these classifications should not be treated as if the prior years disappeared from the tax-residency record.
The Sixth Calendar Year Does Not Automatically Create Resident-Alien Status
After more than five calendar years as an exempt teacher, trainee, or student, the normal student exclusion does not simply continue without further review. IRS rules allow a student to continue excluding days in this category only when the student can establish that there is no intent to reside permanently in the United States and has substantially complied with the requirements of the visa.
The IRS identifies facts such as a closer connection to a foreign country and affirmative steps toward lawful permanent resident status as relevant to that determination. Form 8843 reflects this directly in Lines 12 through 14.
Crossing the five-calendar-year point also does not, by itself, make a person a resident alien. If student days can no longer be excluded, those days may enter the substantial presence test calculation; the resulting tax-residency status then depends on the applicable residency rules and the person’s actual days and circumstances.
Records That Match the Form’s Questions
Form 8843 is easier to complete when the information is taken from records rather than memory. The useful documents are the ones that correspond to the fields on the form.
- Passport information, including the issuing country and passport number.
- I-94 arrival/departure history for the most recent U.S. entry and current nonimmigrant status.
- Form I-797 approval information if a change of status occurred inside the United States.
- A travel record showing actual U.S. presence by calendar year.
- The name, address, and telephone number of the academic institution attended during the tax year.
- Contact information for the director of the academic or specialized program; IRS student-preparation material also recognizes the foreign student adviser as a possible contact when necessary.
- Prior-year F, J, M, or Q status history for the years requested on the form.
- An SSN or ITIN if one has already been issued.
The I-94 record deserves separate attention. A visa document, an entry classification, and current nonimmigrant status can describe different points in time. That distinction is the reason Lines 1a and 1b can sometimes have different answers.
Completing Part I: General Information
An F-1 student who files Form 8843 separately completes all required entries on the form. When Form 8843 is attached to Form 1040-NR, special instructions can reduce duplication in Part I; that filing method is covered later.
Name, TIN, and Address Fields
The top of Form 8843 asks for the individual’s name and U.S. taxpayer identification number, if any. IRS foreign-student training material states that Form 8843 itself does not require an identification number. A student or scholar who is not required to file an income tax return does not need an SSN or ITIN solely to submit Form 8843.
The address boxes have a separate filing rule. The form says to complete the country-of-residence and U.S. address fields only when Form 8843 is 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 type of U.S. visa or nonimmigrant classification and the date of the most recent entry into the United States. For an F-1 student whose most recent entry was in F-1 status, the entry normally reflects that F-1 classification and the corresponding entry date. The IRS instructions direct filers to the CBP I-94 record when confirming the most recent entry.
“Most recent entry” is not necessarily the date the student first came to the United States. Travel outside the country followed by reentry can create a later entry date.
Line 1b: Current Nonimmigrant Status
Line 1b asks for current nonimmigrant status as of the last day of the tax year. In many routine F-1 cases it matches Line 1a, but a status change inside the United States can make the two lines different.
For example, a person may have entered in B-2 status and later received approval to change to F-1 status without leaving the United States. The Form 8843 instructions say that when status changed after the last entry, Line 1b should also include the date of change and the previous status. Form I-797 can provide the approval information for an approved change of status.
Lines 2 and 3: Citizenship and Passport Information
Line 2 asks for the country or countries of citizenship during the tax year. Line 3a asks which country or countries issued the passport, while Line 3b asks for the passport number or numbers. These are separate questions, so citizenship and passport-issuing country should not be treated as interchangeable fields.
Line 4: Actual Presence Versus Excluded Days
Line 4 is where the form separates physical presence from the days claimed as excludable for the substantial presence test.
| Line | What the Form Asks For | What Not to Substitute |
|---|---|---|
| Line 4a | The actual number of days physically present in the United States for each year shown on the form | Do not reduce this field merely because some of those days are being claimed as exempt-individual days |
| Line 4b | The number of days in the current tax year claimed as excludable for purposes of the substantial presence test | Do not automatically copy the physical-presence total unless all of those days are properly excludable |
On the 2025 form, Line 4a asks for actual days present during 2025, 2024, and 2023, while Line 4b asks for the number of 2025 days claimed as excludable. A first-five-calendar-year F-1 case can have the same number on current-year Lines 4a and 4b when every day of U.S. presence for that year falls within the qualifying student period. That equality is not automatic in every case.
A midyear status change illustrates why. If part of the year was spent in a classification whose days are counted and a later part was spent as a qualifying F-1 exempt individual, Line 4a can include the full actual-presence total while Line 4b includes only the days claimed for exclusion.
Completing Part III: Students
For a student in F-1 status, Part III is the student section. Parts II, IV, and V address teachers and trainees, professional athletes, and individuals with a medical condition or medical problem. They are not substitute student sections.
Line 9: Academic Institution
Line 9 asks for the name, address, and telephone number of the academic institution attended during the tax year. IRS foreign-student training material says that when more than one institution was attended during the year, the institution attended at the end of the year is reported.
Line 10: Academic or Specialized Program Director
Line 10 asks for the name, address, and telephone number of the director of the academic or other specialized program. The field is intended to identify a school contact who can verify the student’s participation. IRS training material indicates that a foreign student adviser can be listed when necessary.
Line 11: Prior F, J, M, or Q Status
Line 11 is a visa-status history question, not just a record of the current F-1 year. The final 2025 form lists the six preceding calendar years and asks for the F, J, M, or Q visa type held in each applicable year. For the 2025 form, those years are 2019 through 2024.
If the type of visa or qualifying status changed during one of the listed years, the form directs the filer to attach a statement showing the new type and the date it was acquired. This history matters because prior exempt years can affect the five-calendar-year analysis.
Lines 12–14: More Than Five Calendar Years and Permanent-Residence Steps
Line 12 asks whether the individual was exempt as a teacher, trainee, or student for any part of more than five calendar years. A “Yes” answer triggers an additional requirement on the form: an attached statement with enough facts to establish that the individual does not intend to reside permanently in the United States.
Line 13 then asks whether, during the tax year, the individual applied for lawful permanent resident status, took other affirmative steps to apply for that status, or had an application pending to change status to lawful permanent resident. Line 14 provides space to explain a “Yes” answer.
Line 12 does not ask whether F-1 status has lasted for exactly five uninterrupted years. It asks about calendar years in which the person was exempt as a teacher, trainee, or student.
For a case beyond the normal five-calendar-year student period, these lines are not routine background questions. They connect directly to the IRS facts-and-circumstances test for whether student days may continue to be excluded.
When Form 8843 Is Attached to Form 1040-NR
Form 8843 and Form 1040-NR have different jobs. Form 8843 explains excluded presence days; Form 1040-NR is the federal income tax return used by nonresident aliens when a return is required. Having a Form 8843 filing requirement does not, by itself, prove that Form 1040-NR is also required.
When a 2025 Form 8843 is attached to Form 1040-NR, the Form 8843 instructions allow Lines 1a through 4a to be left incomplete if the requested information has been provided on the corresponding Form 1040-NR lines and Schedule OI. In that situation, Line 1a of Form 8843 is marked “Information provided on Form 1040-NR.” Line 4b and the remainder of Form 8843 still have to be completed as applicable.
The top-of-form address boxes are also different in an attached filing: Form 8843 states that those address fields are completed only when the form is filed by itself.
The signature rule changes as well. Form 8843 says to sign it only when it is filed by itself and not with a U.S. tax return. When it is attached to Form 1040-NR, the separate Form 8843 signature line is not used.
| Form Detail | Form 8843 Filed by Itself | Form 8843 Attached to Form 1040-NR |
|---|---|---|
| Address boxes at top | Complete them | Form says not to complete them for an attached filing |
| Lines 1a–4a | Complete all required entries | May be omitted when corresponding information is supplied on Form 1040-NR/Schedule OI under the Form 8843 instructions |
| Line 4b | Complete as applicable | Complete as applicable |
| Signature on Form 8843 | Required | Not separately signed |
| Submission | Mailed to the Form 8843 standalone address | Submitted with the Form 1040-NR filing |
When Form 8843 Is Filed by Itself
A standalone Form 8843 is used when the individual has a Form 8843 filing requirement but does not have to file a federal income tax return for the year. The Form 8843 instructions require all applicable entries to be completed for a separate filing, and the form is signed and dated.
For the 2025 tax year, the standalone mailing address printed in the Form 8843 instructions is:
Department of the Treasury
Internal Revenue Service Center
Austin, TX 73301-0215
The IRS instructs standalone filers to use the due date, including extensions, that applies to Form 1040-NR. Under the 2025 Form 1040-NR instructions, a calendar-year individual who did not receive employee wages subject to U.S. income tax withholding generally uses the 15th day of the sixth month after year-end, which was June 15, 2026 for the 2025 tax year. A Form 1040-NR filer who received employee wages subject to U.S. income tax withholding generally uses the 15th day of the fourth month; for the 2025 calendar year, that date was April 15, 2026.
Mailing addresses and calendar dates can change with a later tax-year revision, so the Form 8843 and Form 1040-NR instructions for the year being filed control the final submission details.
F-2 Spouses and Children Use Separate Forms
Form 8843 is an individual statement. An accompanying F-2 spouse or child is not added to the F-1 student’s Form 8843 as another person on the same filing. IRS foreign-student material says accompanying spouses and children in related statuses such as F-2 complete the same sections as the primary F-1 student when the exempt-individual rules apply to them.
That means a family can have several Forms 8843 for the same year. Each person’s U.S. presence and tax-residency analysis is separate. For a minor child who cannot sign, IRS student-preparation instructions allow a parent, guardian, or another legally responsible person to sign for the child using the IRS-prescribed notation.
OPT or CPT Does Not Reset the Five-Year Count
Employment authorization connected with F-1 study does not create a new five-calendar-year period for Form 8843. The tax-residency question remains tied to the student exempt-individual rules, prior exempt years, actual days of presence, and whether the student remains within the period in which student days can be excluded.
As a result, the fact that an F-1 student is working during OPT or CPT does not answer the Form 8843 question by itself. Income-tax return requirements and the treatment of employment income are separate issues from whether days are excluded for the substantial presence test.
A Worked Day-Count Example
Consider an F-1 student whose first exempt calendar year was 2024 and who remained in qualifying F-1 student status throughout 2025. Assume the student was physically present in the United States for 240 days during 2025 and all 240 days fall within the period treated as exempt-individual student days.
For 2025 Form 8843 purposes, Line 4a would reflect 240 actual days of U.S. presence for 2025. Line 4b would reflect 240 days claimed as excludable for the substantial presence test. The student was physically in the country; the day-counting rule is what keeps those qualifying days out of the substantial presence calculation.
Change one fact and the form can look different. If 40 of the 240 days occurred before the person entered the qualifying F-1 student period, Line 4a could still show 240 actual days while Line 4b would require a separate determination of which days are properly excludable. The form should not be completed by assuming Line 4a and Line 4b always match.
Use the Final Form for the Tax Year Being Filed
Form 8843 is revised by tax year. The line years, filing dates, and instructions should be taken from the final IRS version for the year being filed rather than copied from an older form.
The IRS has published a 2026 Form 8843 draft, but that document is marked DRAFT — DO NOT FILE. A draft is useful for seeing proposed form structure, but it is not a filing version. For a 2025 filing, the final 2025 Form 8843 and its instructions remain the relevant form.
