IRS Form 8843: complete filing guide for international students

If you spent any part of 2025 in the United States on an F, J, M, or Q visa and are claiming excluded days under the substantial presence test, Form 8843 is the IRS form you use, even if you had no income.

This Form 8843 guide is written for the people who actually file the form: international students, J-1 scholars, M-1 vocational students, Q exchange visitors, their F-2, J-2, M-2, and Q-3 dependents, no-income filers, and anyone who had to stay in the US because of a medical condition.

The About Form 8843 page on IRS.gov hosts the current version, and the Form 8843 PDF is what you actually print, sign, and mail.

Most international students need to file it. Most do not realize that until tax season starts.

Quick answer

• Who files: F, J, M, and Q visa holders claiming excluded days under the substantial presence test, plus their dependents doing the same, and anyone unable to leave the US due to a medical condition that began while present
• Deadline: for tax year 2025, April 15, 2026, if filed with Form 1040-NR and US wage withholding, or June 15, 2026, if standalone or no wages subject to withholding (same structure applies for tax year 2026: April 15, 2027, and June 15, 2027).
• Mailing address (standalone): Department of the Treasury, Internal Revenue Service Center, Austin, TX 73301-0215.
• If you do not file: the IRS can refuse to exclude your days, which may reclassify you as a US resident alien for tax purposes.

What is Form 8843?

IRS Form 8843 is an information statement filed with the IRS, not a tax return. Its full name is "Statement for Exempt Individuals and Individuals With a Medical Condition."

You file it to tell the IRS that certain days you spent in the United States should not count toward the substantial presence test, the rule the IRS uses to decide whether you are a nonresident or resident alien for tax purposes.

The 8843 tax form does not calculate any tax. It does not report income. It does not generate a refund. Its only job is to claim and document excluded days of US presence.

Three categories of people use it:

• Qualifying students and exchange visitors, along with their dependents. F, J, M, and Q visa holders who meet the exempt-individual rules can exclude their days of US presence from the substantial presence test while that status applies.
• Professional athletes at charitable events. Athletes present in the US solely to compete in a charitable sports event can exclude the days they spend at that event.
• People with a medical condition. If a medical condition that began while you were in the United States kept you from leaving, the days you intended to leave but could not can be excluded through Part V of the form. IRS Publication 519 explains the medical-condition rule in detail, including the documentation expected.

If you are required to file Form 1040-NR, attach Form 8843 to that return. Having some US-source income does not automatically mean you must file Form 1040-NR. The federal Form 8843 is part of that return package, not a substitute for it. If you have no US income, the form stands on its own.

Here is the practical answer to what the 8843 form is used for: the US tax form 8843 supports your claim to exclude certain days under the substantial presence test. Without a timely filing, the IRS may not allow those exempt days to be excluded, which can affect your residency status.

Who needs to file Form 8843?

If you spent time in the US during 2025 on an F, J, M, or Q visa, the answer is almost certainly yes. The form is required for all exempt individuals under the substantial presence test, regardless of income, and it applies to dependents as well as the primary visa holder.

Each person files their own form. That includes children.

Every F, J, M, and Q visa holder treated as an exempt individual files Form 8843, along with their dependents on those visa categories. Q-3 dependents should be checked against the current IRS instructions. US citizens, green card holders, and resident aliens do not file

 

A few rules to keep straight

• Students. F-1, J-1 student, M-1, and Q student visa holders qualify as exempt individuals under the student rules for up to 5 calendar years. Q visa teachers and trainees follow the same two-year rule as J-1 teachers and trainees. Any part of a year counts as a full year, so arriving in August still uses up the whole calendar year.
• Teachers, trainees, and researchers. J-1 and Q visa holders in non-student categories are exempt for 2 calendar years out of the last 6.  An additional "compensation from a foreign employer" test, set out in the IRS guidance for teachers and trainees, can extend that window in some cases.
• Dependents. F-2, J-2, and M-2 dependents generally file their own Form 8843 when they qualify under the exempt-individual rules. A 4-year-old on F-2 still files Form 8843, even with no income, no SSN, and no idea what the IRS is. Q-3 dependents should be checked against the current IRS instructions before being grouped automatically. Parents miss both points often

Do you need Form 8843 if you had no income?

Yes. Nonresident F, J, M, and Q visa holders generally need to file Form 8843 even if they earned nothing in the United States during 2025. The filing requirement is tied to exempt-individual status under the substantial presence test, not to income.

Standalone vs. attached to Form 1040-NR

How you submit the form depends entirely on whether you have US income to report.

• No US income. You file Form 8843 by itself. Print it, sign it, and mail it to the standalone address. There is no return to attach it to.
• If you are required to file Form 1040-NR, attach Form 8843 to that return and file them together. The 8843 travels with the return rather than going to a separate address.

That distinction is the heart of the Form 8843 no income rule. The statement is required for exempt individuals regardless of income.

Why the "no income, no filing" assumption fails

Many international students arrive thinking that no income means no tax paperwork. For US citizens at the federal level, that is sometimes true. For nonresident exempt individuals, it is not.

The form is not a tax return. It is the document that lets you exclude your days from the substantial presence test. Skip the form, and the days you spent in the US during 2025 count toward residency, even though you owed nothing. That is the part that catches people off guard, the year they finally do owe something, because by then their residency status has quietly shifted.

Form 8843 deadline and due date

For tax year 2025, your Form 8843 deadline lines up with the Form 1040-NR due date that applies to your situation. Two dates matter: April 15, 2026, and June 15, 2026.

The two possible due dates

Which date applies depends on whether you file Form 1040-NR and whether you received US wages subject to income tax withholding.

• April 15, 2026. Applies if you file Form 1040-NR and received wages subject to US income tax withholding. The 8843 attaches to the return and shares its deadline.
• June 15, 2026. Applies in two situations: you file Form 1040-NR but had no wages subject to US withholding, or you have no return to file and submit Form 8843 on its own. The standalone Form 8843 due date is the same as the 1040-NR due date for no-withholding filers.

Extensions

For Form 8843 extension requests, the rule depends on how you file.

If Form 8843 is attached to Form 1040-NR, it follows that the return's deadline, including any automatic six-month extension requested on Form 4868, which pushes the deadline to October 15, 2026.

If Form 8843 is filed by itself, follow the Form 1040-NR due date listed in the Form 8843 instructions. Standalone filers who miss June 15 should still send the form as soon as possible, with a short cover letter explaining the delay.

The IRS may still allow the exclusion if you can show by clear and convincing evidence that you took reasonable actions to learn about the filing requirement and significant steps to comply, but acceptance is not guaranteed.

Looking ahead to tax year 2026

The same structure applies one year forward. Tax year 2026 filings would be due April 15, 2027, or June 15, 2027, depending on the same conditions. Calendar dates change; the rule does not.

How to fill out Form 8843

Form 8843 has five parts. You complete Part I plus the one later part that matches your status. Most readers fill in two parts total, not all five.

The part you file depends on your visa or status: Part II for J-1 and Q visa teachers and trainees; Part III for students on F, J, M, and Q visas; Part IV for professional athletes at a charitable sports event; Part V for medical condition cases. Everyone completes Part I.

Step by step

Part I: General information. Asks for your name, taxpayer ID (SSN or ITIN, if you have one), address in your home country and in the US, visa type, current nonimmigrant status, and the number of days you were physically present in the US in 2023, 2024, and 2025. Line 4b asks how many of those days you claim as excluded.

Part II: Teachers and trainees. For J or Q visa teachers and trainees. If you have a Q visa, complete Part I and only lines 6 through 8 of Part II. Asks for the name, address, and phone of the academic institution or program sponsor, the director's name and contact, and the type of US visa you held in each of the prior six calendar years. The exempt window for this group is two calendar years out of the last six.

Part III: Students. The part most readers complete. Asks for the school's name, address, and phone, the academic program director's name and contact, the type of US visa held in each of the last six years, and two judgment questions: whether you have applied for permanent residence, and whether you have taken any steps toward it. Answer both honestly. The five-year exempt window applies to this group.

Part IV: Professional athletes. A short section for athletes present at a US charitable sports event. Asks for the name and address of the charitable sports event and the dates of competition. Only days at the qualifying event are excluded, not training days or unrelated US time.

Part V: Medical condition. For days you intended to leave the US but could not because of a medical condition that began while you were here. Asks for the dates of the condition, a description, and the physician's name, address, and phone. Have your physician or other medical official complete line 18 on Form 8843.

A short Form 8843 example

TFX client scenario: a German citizen on an F-1 visa first arrived in August 2022, was physically present in the US for 240 days in 2025, and earned no US income for the year. She files Form 8843 standalone, completes Part I (listing 240 days present and 240 days excluded) and Part III (her university, program director, and F-1 status for 2022 through 2025), and mails the form by June 15, 2026.

How to file Form 8843

Form 8843 is filed on paper in most cases. There are two paths, depending on whether you also file a return.

Two filing paths

• With Form 1040-NR. If you have US income that requires a return, attach Form 8843 behind the 1040-NR and file them together. The 8843 transmits as part of the return. If you e-file the 1040-NR through approved software, the attached 8843 goes with it electronically.
• Standalone. If you have no return to file, print Form 8843, sign and date Part I, and mail the paper form. There is no e-file path for a Form 8843 sent on its own; the Form 8843 submission has to go through the mail.

Before you submit

Three things matter before the envelope leaves your hands.

• Sign and date Form 8843 if you are filing it by itself. If it is attached to Form 1040-NR, the signature belongs on the return package.
• Use the correct year. The 2025 form is what you submit Form 8843 for the 2025 tax year. Prior-year filings use the prior-year version.
• Keep a copy. Photocopy or scan the signed form before mailing. If the IRS later questions your residency classification, the dated copy is your evidence that the form was filed.

Mailing by a method that provides delivery confirmation (USPS Certified Mail, FedEx, or DHL with tracking) is worth the extra few dollars when you are abroad and cannot easily follow up.

Where to mail Form 8843

The address depends on whether you file the form by itself or attach it to Form 1040-NR.

Standalone mailing address

The Form 8843 mailing address for filers with no return is:

Department of the Treasury Internal Revenue Service Center Austin, TX 73301-0215

That single address handles all standalone filings, regardless of which state you lived in during 2025 or which country you mail from. There is no separate address for international mail; the Austin processing center receives every standalone form.

When filing with Form 1040-NR

If your Form 8843 is attached to a Form 1040-NR, do not use the Austin address above. Use the address printed in your current-year Form 1040-NR instructions. That address depends on whether you are enclosing a payment with the return, and the IRS uses different processing centers for the two cases.

Where to send the 8843 form for family members

Each person files their own complete, signed form, but you can either mail them in separate envelopes or combine them in one. The IRS accepts either. Separate envelopes make tracking easier if one form is later questioned; a single envelope saves postage.

Whichever option you choose, do not staple multiple people's forms together. Use paper clips, or place each form loose in the envelope so the processing center can separate them.

What happens if you do not file Form 8843?

There is no flat-dollar penalty for not filing Form 8843. The form has no late-filing fine and no per-day charge.

The consequence is different, and in many cases, more expensive than a fine would be.

The real consequence: lost day exclusion

Without a timely filing, the IRS may not allow your exempt-individual days to be excluded from the substantial presence test. For a student in year three of a five-year exempt window, that can be enough to meet the test and shift you into US resident alien status

Resident classification changes the tax picture significantly:

• Worldwide income becomes reportable
• Treaty positions you relied on may no longer hold
• The forms you owe shift from the nonresident set to the resident set

The shift can be quiet. A student with no US income one year, and back home the next, can cross into resident status without noticing.

The first sign is usually a tax bill years later, when they get a US job after graduation. By then, the missed Form 8843 will be several years in the past.

Reasonable-action exception

A late filing can still claim the day exclusion if you can show two things by clear and convincing evidence:

• You took reasonable actions to become aware of the filing requirement
• You took significant steps to comply once you knew

A written explanation is attached to the late form.

This is not automatic relief. Each request is reviewed on its own facts.

Documentation matters. Emails to your school's international office, dated copies of any research you did, a record of when you discovered the missed filing — all useful. A bare "I did not know" without supporting context tends to fail.

If your classification is unclear, the resident and nonresident alien rules walk through how the test treats specific situations.

Filing Form 8843 late or for previous years

If you missed a year, you can still file. Filing Form 8843 late is common among international students who only realized the requirement later.

The IRS does not automatically forgive late filings, but it does process them. Here is how.

What to do, in five steps

1. Identify which years you missed.

Each calendar year you spend in the US as an exempt individual needs its own form. Missed 2022, 2023, and 2024? That is three forms.

2. Download the correct prior-year version.

The 2023 form is not the 2025 form. Line numbering changes. Use the prior-year forms page to get the right version for each missed year.

3. Complete one form per year, separately.

Do not combine years on a single form. Form 8843 for previous years means one form per tax year, each signed and dated.

4. Attach a short cover letter.

One or two paragraphs are enough. State that the filing is late, briefly explain why, and confirm you took action as soon as you became aware of the requirement.

Keep it factual. Do not promise penalty relief or claim entitlements you have not been granted.

5. Mail everything together to the standalone address.

Department of the Treasury, Internal Revenue Service Center, Austin, TX 73301-0215. Send by a method with delivery confirmation if you can.

What to expect

The IRS may accept the day exclusion. It may not. Form 8843 late filing acceptance depends on whether you can demonstrate by clear and convincing evidence that you took reasonable actions to learn about the requirement and significant steps to comply once you did

A Form 8843 late submission does not generate a tax bill on its own. The form itself owes nothing. But if your residency status would have been different in the missed years, accepting or rejecting the late form can change the tax you owe for those years.

If the missed years overlap with US income reported as nonresident (1040-NR), and the late 8843 is rejected, you may need to amend those returns as a resident filer. That is more involved than the 8843 itself, and is worth a preparer's review before mailing.

Filing for the current prior year only

If the only year you missed is the one just past, for example, you forgot to file your Form 8843 for the previous year when you submitted nothing in 2025, the process is the same, but expectations are better. The IRS treats single-year late filings closer to the original deadline more favorably than multi-year backlogs filed many years later.

Form 8843 vs Form 1040-NR vs Form 8840

Form 8843 excludes days from the substantial presence test. Form 1040-NR is the nonresident income tax return that calculates tax, and Form 8840 claims the closer connection exception for foreign nationals who otherwise meet the substantial presence test.

 

When it comes to the Form 8843 tax return relationship, you may file Form 1040-NR alone, Form 8843 alone, both together, or Form 8840 only if you meet the substantial presence test and are claiming the closer-connection exception

Form 8843 for F-1 international students

The five-calendar-year cap on exempt-individual status is the rule that catches most Form 8843 for international students filers off guard.

The five-year exempt window

An F-1 student is generally treated as an exempt individual for no more than 5 calendar years. Any part of a year counts as a full year.

Arrived in August 2021? Your five calendar years are 2021, 2022, 2023, 2024, and 2025. Starting January 1, 2026, your days begin counting toward the substantial presence test.

After year five, you can continue as an exempt individual only if you do not intend to reside permanently in the United States, you have substantially complied with your visa requirements, and the facts and circumstances support that position, including your closer connection to a foreign country. This is not automatic. You need to be able to support all of these points if asked.

Form 8843: F-1 student filing in years one through five

In years one through five, the filing is straightforward. Complete Parts I and III only, regardless of income or tuition coverage.

The standard pattern: standalone filing every year, no return required, mailed by June 15 of the following year. For tax year 2025, that means June 15, 2026.

The international student tax form 8843 filer in this window does not need an SSN, does not need a return, and does not need to explain anything beyond their visa status and days present.

OPT does not change the rule

Common misconception: OPT (Optional Practical Training) changes your filing obligation. It does not.

While you are on OPT and still in F-1 status within your five-year window:

• You remain an exempt individual for substantial presence purposes
• You still file Form 8843
• If you have OPT wages, you file Form 1040-NR with the 8843 attached

The visa status is what matters for the 8843, not whether you are studying or working.

Dependents on F-2 visas

F-2 dependents file their own Form 8843. Every spouse and every child, regardless of age.

Parents miss this often because:

• The dependent has no income
• The dependent has no SSN
• The dependent does not file a US return otherwise

None of those facts removes the 8843 requirement. The form is how the IRS knows their days do not count either.

Common F-1 mistakes

Students filing the Form 8843 tax statement typically trip on the same few points:

• Treating "no income" as "no filing"
• Forgetting the dependents
• Counting the wrong number of US days (the I-94 travel history at i94.cbp.dhs.gov is the source of truth)
• Filing year six and beyond as exempt without meeting the additional facts-and-circumstances test
• Using the current year's form for a prior year

Common Form 8843 mistakes

Six errors come up repeatedly in client files. Each one can delay processing, void the day exclusion, or both.

1. Using the wrong year's form. The 2024 form is not the 2025 form. Line numbering and instructions have changed. Always download the version that matches the tax year you are filing for.
2. Forgetting to sign and date the standalone form. The IRS instructions require a signature when you file Form 8843 by itself. If the form is attached to Form 1040-NR, the signature on the return covers it.
3. Using the wrong address. Standalone forms go to Austin, TX 73301-0215. Forms attached to Form 1040-NR follow the 1040-NR instructions address, which depends on whether you enclose a payment. Sending an attached 8843 to Austin can separate it from the return it belongs with.
4. Filing one envelope with one form for the whole family. Each family member needs their own complete, signed form. You can mail them in one envelope, but the forms inside must be individual.
5. Assuming "no income" means "no filing." Among new international students, this is the most frequent mistake. Exempt-individual status drives the filing requirement, not income.
6. Confusing immigration status with tax residency. Being in legal F-1 status does not automatically make you a nonresident alien for tax purposes. Form 8843 is part of how you make sure you are treated as one. Conversely, leaving F-1 status mid-year does not automatically end your nonresident classification for that year.

Need help filing Form 8843 or Form 1040-NR?

Most students can complete a standalone Form 8843 on their own. The form is short, the address is fixed, and the parts that apply are clear once you know your visa category.

The harder cases are the ones that have something else going on:

• A nonresident return with treaty benefits or scholarship income
• A first US tax year as a working professional after years on F-1 status
• A dual-status year where you crossed from nonresident to resident mid-year
• Multiple missed years that need to be filed at once
• An F-2 spouse with foreign income and questions about joint filing

TFX prepares nonresident returns, F-1 and J-1 student filings, dual-status returns, and late catch-ups every filing season.
