When Is the Tax Filing Deadline for F-1 Students?
Quick Answer
The federal tax filing deadline for F-1 students filing Form 1040-NR is April 15. Form 8843 (required even with no income) is due June 15 if filed independently. Students outside the US on April 15 with no US wages may qualify for an automatic extension to June 15.
Key Takeaway
Mark April 15 on your calendar for filing Form 1040-NR, and June 15 for Form 8843 if you had no income. File early to avoid penalties, and request an extension using Form 4868 if you need more time.
Federal Tax Filing Deadlines
F-1 students who earned US-source income must file Form 1040-NR by April 15 of the year following the tax year. For the 2025 tax year, the deadline is April 15, 2026. This is the same deadline that applies to US citizens and residents filing Form 1040, though the forms and rules differ significantly.
If you did not earn any US-source income but were present in the US during the tax year, you must still file Form 8843. When Form 8843 is your only filing obligation (no income to report), the deadline is June 15. This extended deadline recognizes that students with no income may not be aware of their filing obligation as early.
When you file Form 1040-NR and Form 8843 together (because you had income), both forms should be submitted by the April 15 deadline. Form 8843 is attached to your 1040-NR as part of the complete return.
Extensions and Special Circumstances
If you cannot file by April 15, you can request an automatic six-month extension by filing Form 4868 (Application for Automatic Extension of Time to File U.S. Individual Income Tax Return) by the April 15 deadline. This extends your filing deadline to October 15 but does not extend the deadline for paying any taxes owed. Interest and penalties accrue on unpaid taxes from April 15.
If you are outside the United States on April 15 and your primary income is not subject to US wage withholding, you may qualify for an automatic two-month extension to June 15 without filing Form 4868. To use this provision, attach a statement to your return explaining that you were outside the US on the regular due date. Note that interest on unpaid taxes still accrues from April 15, even with this extension.
- April 15: Deadline for Form 1040-NR (with income)
- June 15: Deadline for Form 8843 (no income, filed separately)
- October 15: Extended deadline if Form 4868 is filed by April 15
- June 15: Automatic extension if outside US on April 15 with no US wages
An extension to file is not an extension to pay. If you owe taxes, you must estimate and pay the amount due by April 15 to avoid interest and penalties.
State Tax Filing Deadlines
State tax filing deadlines generally mirror the federal April 15 deadline, but this is not universal. Some states have different deadlines or offer different extension rules. For example, Virginia's deadline is May 1, and some states automatically extend the deadline if you receive a federal extension.
Check your state's department of revenue or taxation website for the specific deadline and extension procedures. If you earned income in multiple states, you may need to track multiple deadlines. Filing state returns is typically easier after completing your federal return, since state forms often reference your federal adjusted gross income.
Penalties for Late Filing
Filing your tax return late can result in penalties and interest charges. The failure-to-file penalty is typically 5% of the unpaid tax for each month or part of a month the return is late, up to a maximum of 25%. The failure-to-pay penalty is 0.5% of the unpaid tax per month. Interest is charged on both unpaid taxes and penalties.
If you are due a refund, there is no penalty for filing late—but there is a time limit. You generally have three years from the original due date to file and claim your refund. After three years, the refund is forfeited. Many F-1 students are due refunds because of over-withholding by employers, so filing promptly is in your financial interest even if you are not worried about penalties.
