- International students must file Form 8843 by April 15 or June 15 depending on income status.
- Form 8843 is essential to maintain nonresident tax status and exclude U.S. days from residency tests.
- Missing these 2026 deadlines can impact future immigration benefits like OPT and visa renewals.
(UNITED STATES) — International students and exchange visitors who were in the United States during 2025 must watch two 2026 tax deadlines for Form 8843: April 15, 2026, if they had U.S. income, and June 15, 2026, if they had no income and are filing Form 8843 only.
This deadline alert is current as of April 1, 2026. It applies to 2025 federal filings due in 2026, not tax year 2026 returns filed in 2027.
For many students, this is the form they overlook. That can create tax and immigration problems.
What Form 8843 is and why it matters
Form 8843 is an informational statement, not a tax return. The IRS uses it to document that a nonresident alien is an exempt individual for the Substantial Presence Test.
That “exempt” label does not mean exempt from tax in general. It means certain days in the United States do not count toward the residency formula.
For an international student in F-1 status, filing Form 8843 can exclude up to 5 calendar years of U.S. presence from resident-alien status under the Substantial Presence Test. The same rule can apply to certain J, M, and Q visa holders, depending on category and facts. IRS Publication 519, U.S. Tax Guide for Aliens, is the main reference.
If those days are not excluded, you could be treated as a resident alien for tax purposes earlier than expected. That may require reporting worldwide income and could affect treaty benefits.
📅 Deadline Alert: If you had U.S. income in 2025, Form 8843 is generally attached to Form 1040-NR and due April 15, 2026.
Who must file in 2026
The filing requirement is broad. If you were present in the United States for even one day in 2025, you generally must file Form 8843 if you held one of these statuses:
- F-1 or F-2
- J-1 or J-2
- M-1 or M-2
- Q-1 or Q-2
This applies even if you had no income at all.
If you are filing Form 8843 only, you do not need an SSN or ITIN. If you had income and must file Form 1040-NR, other identification rules may apply.
Deadline summary
| Filing situation | Form(s) | Deadline | Extension available |
|---|---|---|---|
| No U.S. income in 2025 | Form 8843 only | June 15, 2026 | No standard income tax extension applies to a stand-alone Form 8843 filing |
| U.S. income in 2025 | Form 8843 + Form 1040-NR | April 15, 2026 | Form 4868 may extend the tax return filing to October 15, 2026 |
| FBAR, if required | FinCEN Form 114 | April 15, 2026 | Automatic extension to October 15, 2026 |
If you had foreign accounts over $10,000 aggregate at any point in 2025, review FBAR rules separately. Form 8843 does not replace FinCEN Form 114.
What happens if you miss it
Missing Form 8843 can have real consequences.
First, the IRS may count your U.S. days toward the Substantial Presence Test if you do not properly claim the exempt-individual rule. That can shift you into resident alien tax status.
Second, if you had income and failed to file Form 1040-NR, normal tax penalties may apply. These can include:
- Failure-to-file penalty of 5% of unpaid tax per month, up to 25%
- Failure-to-pay penalty of 0.5% of unpaid tax per month
- Interest on unpaid tax
Third, immigration records may be affected. Source materials cited here state that USCIS policy guidance dated January 1, 2026 ties tax compliance to evidence of maintenance of status for benefits such as OPT and Form I-539 filings. The article materials also cite 8 CFR 214.2 and a SEVP handbook update dated July 31, 2025, stating that tax filings can serve as evidence of status maintenance.
⚠️ Warning: A missed Form 8843 does not automatically end status, but late or missing tax filings can create avoidable questions during OPT, visa renewal, or change-of-status review.
Why students should treat this as both a tax and documentation issue
For F-1 students, this is not just an IRS form. It is also part of your paper trail.
Future visa applications, consular interviews, and some immigration benefit filings may ask for proof that you followed U.S. rules. Tax compliance records can help. Your I-94 travel history is also important because Part I of Form 8843 asks for arrival information and days present.
The article materials also mention heightened scrutiny in 2026 for some students. In that setting, timely filing works as a protective step.

If you are unsure whether you are still a nonresident alien, review the Substantial Presence Test rules in Publication 519. F-1 and J-1 students often remain exempt from counting days for a limited period, but the rule is not indefinite.
💡 Tax Tip: Keep copies of your passport, visa, I-20 or DS-2019, I-94, and filed Form 8843 each year. Those records can help with both tax and immigration questions.
Before the deadline, gather your I-94, check whether you had any 2025 U.S. income, confirm whether you need Form 1040-NR, and file Form 8843 by the correct date. If you changed status, claimed treaty benefits, or spent more time in the United States than expected, get advice before filing.
