The Ultimate F-1 Student Tax Guide (2026)
The most comprehensive, step-by-step guide to US tax filing for international students on F-1 visas. Covers every form, every deadline, FICA refunds, tax treaties for 15+ countries, state taxes, software comparisons, and the mistakes that cost students thousands of dollars.
Key Takeaway
Every F-1 student in the United States must file at least Form 8843 — even if you earned zero income. If you had any US-source income (wages, scholarships, stipends, bank interest), you must also file Form 1040-NR. Most F-1 students are non-resident aliens for their first 5 calendar years and are exempt from FICA taxes (Social Security + Medicare = 7.65% of wages). Filing incorrectly — or not filing at all — can jeopardize future visa applications, green card petitions, and H-1B transfers.

1. Do F-1 Students Need to File Taxes?
Yes — without exception. Every F-1 student who was physically present in the United States during any part of the calendar year is required to file at least one form with the IRS. This is true regardless of whether you earned a single dollar.
The IRS requires all F-1, F-2, J-1, and J-2 visa holders to file Form 8843 ("Statement for Exempt Individuals and Individuals with a Medical Condition"). This is an informational return — not a tax payment form. It tells the IRS that you are an "exempt individual" under the Substantial Presence Test and should not be counted as a US resident for tax purposes.
You MUST File If:
- • You were physically present in the US on F-1 status at any point during 2025
- • You received any US-source income — wages, scholarships, stipends, bank interest
- • You had federal or state taxes withheld and want a refund
- • You are claiming a tax treaty benefit to reduce your tax burden
- • You received a 1042-S for fellowship or scholarship payments
No Income? You Still File Form 8843
Failure to file Form 8843 does not trigger an immediate penalty. However, it can create complications for future visa applications, green card petitions (I-485), H-1B transfers, and any USCIS status change. Immigration attorneys consistently recommend filing it every year you are in the US.

2. Resident vs Non-Resident Alien for Tax Purposes
Your tax classification — resident alien or non-resident alien (NRA) — determines which form you file, which deductions you can claim, whether your worldwide income is taxed, and whether you qualify for FICA exemption. The IRS determines this using the Substantial Presence Test (SPT).
The Substantial Presence Test Formula
You are a resident alien if your day count meets both conditions:
Days present in current year ≥ 31
AND
(Days in current year × 1) + (Days in year-1 × ⅓) + (Days in year-2 × ⅙) ≥ 183
However, F-1 students get a critical exemption: days spent in the US as an "exempt individual" on F-1 status are excluded from the SPT count for the first 5 calendar years.
• Arrived August 2021 → Exempt through all of 2025 (5 calendar years: 2021, 2022, 2023, 2024, 2025)
• Arrived January 2023 → Exempt through all of 2027 (5 calendar years: 2023, 2024, 2025, 2026, 2027)
• Arrived August 2019 → Exempt ended after 2023; take the SPT for 2024 onward
| Factor | Non-Resident Alien (NRA) | Resident Alien (RA) |
|---|---|---|
| Tax Form | 1040-NR | 1040 (same as US citizens) |
| Income Taxed | US-source income only | Worldwide income |
| Standard Deduction | Not available (treaty exceptions) | $15,000 (2025 tax year) |
| FICA Exemption | Yes (first 5 calendar years) | No — full 7.65% withheld |
| Tax Treaty Benefits | Yes, if applicable | Generally not available |
| Filing Status Options | Single or Married NRA | All statuses (incl. Head of Household) |
| Education Credits | Not eligible | Eligible (AOTC, LLC) |
| Earned Income Credit | Not eligible | May be eligible |
Critical: Filing as a resident alien when you are a non-resident — or vice versa — is the single most costly mistake F-1 students make. It can result in IRS notices, incorrect refunds that must be returned with interest, and immigration complications. Use the TrackMyOPT Tax Tool to determine your exact classification.
3. Tax Forms Every F-1 Student Needs to Know
International students deal with a unique set of IRS forms. Here is every form you may encounter, who needs it, and when it is due. Refer to our Immigration Glossary for definitions of unfamiliar terms.
Form 8843
Who: ALL F-1/F-2/J-1/J-2 visa holders present in the US
Declares your exempt status under the Substantial Presence Test. Not a tax return — no tax is calculated. Required even with zero income.
Deadline: June 15, 2026 (no income) or April 15, 2026 (attached to 1040-NR)
Form 1040-NR
Who: Non-resident aliens with US-source income
The non-resident alien federal income tax return. Reports wages, taxable scholarships, fellowship grants, and other US-source income. Attach Form 8843.
Deadline: April 15, 2026 (extensions available to October 15)
W-2 (from employer)
Who: F-1 students who worked on-campus, CPT, or OPT
Reports annual wages and taxes withheld by each employer. Check Box 4 (Social Security) and Box 6 (Medicare) for incorrect FICA withholding.
Deadline: Employer must issue by January 31
1042-S (from payer)
Who: Students who received scholarships, fellowships, or treaty-exempt income
Reports income paid to non-resident aliens that is subject to withholding. Common for scholarship/fellowship payments and tax treaty-exempt wages.
Deadline: Payer must issue by March 15
Form 843
Who: F-1 students who had FICA taxes incorrectly withheld
Claim for refund of erroneously collected Social Security and Medicare taxes. File with copies of W-2, I-20, visa stamp, and a written explanation.
Deadline: Within 3 years of the original filing deadline
Form 8233
Who: F-1 students claiming tax treaty exemption on wages
Given to your employer before they pay you so they can apply the treaty exemption at source (less withholding from each paycheck).
Deadline: Submit to employer before wages are paid
4. Form 8843: Step-by-Step Instructions
Form 8843 is a 2-page IRS form that takes about 10–15 minutes to complete. It is the single most important form for F-1 students because it establishes your exempt status under the Substantial Presence Test. Here is how to fill out each section.
Part I — General Information
Enter your name, SSN or ITIN (write 'APPLIED FOR' if you don't have one), and current US address. If you are filing a joint 8843 with a spouse, each person needs their own form.
Part II — Teachers & Trainees
Skip this section entirely. Part II is for J-1 teachers and researchers, not F-1 students.
Part III — Students
This is the key section for F-1 students. Enter your visa type (F-1), the date you entered the US, your university name, and your program of study. List all years you have been present in the US as a student (e.g., 2021, 2022, 2023, 2024, 2025). This establishes your 5-year exemption period.
Part IV — Professional Athletes
Skip this section. It applies to professional athletes only.
Where to Mail Form 8843
If filing Form 8843 by itself (no income, no 1040-NR), mail it to:
Internal Revenue Service Center
Austin, TX 73301-0215
If filing with Form 1040-NR, attach Form 8843 to your 1040-NR and mail to the address specified in the 1040-NR instructions for your state.
Download Form 8843 from IRS.gov (PDF) . Our Tax Filing Assistant can pre-fill your 8843 based on your OPT timeline.
5. Form 1040-NR: Filing as a Non-Resident
Form 1040-NR is the federal income tax return for non-resident aliens. If you are an F-1 student within your first 5 calendar years and you earned any US-source income, this is the form you file — not the standard 1040.
When You Must File 1040-NR
- You earned wages from on-campus employment, CPT, or OPT
- You received a taxable scholarship or fellowship (amount exceeding tuition & required fees)
- You had US-source bank interest income
- You received royalties, rental income, or capital gains from US sources
- You want to claim a refund of over-withheld federal taxes
Income Types Reported on 1040-NR
| Income Type | Source Document | Where on 1040-NR |
|---|---|---|
| Wages & salary | W-2 | Line 1a |
| Taxable scholarship/fellowship | 1042-S or university letter | Line 1a (or Schedule NEC) |
| Tax treaty exempt income | 1042-S | Line 1a with treaty claim on Schedule OI |
| Bank interest | 1099-INT | Schedule NEC (flat 30% or treaty rate) |
| Capital gains | 1099-B | Schedule NEC or Schedule D |
Deductions: Non-resident aliens generally cannot claim the standard deduction. Exceptions exist for students from India (under the US-India treaty, Article 21). NRAs can claim itemized deductions for state/local taxes paid, charitable contributions to US organizations, and casualty/theft losses.
6. FICA Tax Exemption: The 5-Year Rule
FICA stands for the Federal Insurance Contributions Act and includes two taxes: Social Security (6.2%) and Medicare (1.45%) — a combined 7.65% of your gross wages. Under IRC Section 3121(b)(19), F-1 students are exempt from FICA during their first 5 calendar years in the US.
"F-1 students are exempt from FICA taxes for services performed to carry out the purpose of their visa. This exemption saves $3,825 for every $50,000 earned — money that most students never reclaim."
— IRS Publication 519, IRC § 3121(b)(19)
How the 5-Year Rule Works
- The 5 years are calendar years, not full 365-day periods. Even arriving in December counts as year 1.
- The exemption applies to F-1 students performing services related to their visa purpose (on-campus work, CPT, OPT, STEM OPT).
- Starting in calendar year 6, you must pass the Substantial Presence Test. If you become a resident alien, FICA is owed.
- The exemption also covers F-1 students working on STEM OPT — employers must not withhold FICA for exempt students.
How to Get a FICA Refund (Step-by-Step)
1. Check your W-2
Look at Box 4 (Social Security tax withheld) and Box 6 (Medicare tax withheld). If either is greater than $0, FICA was incorrectly withheld.
2. Request a refund from your employer
Contact payroll and ask them to correct the withholding by filing Form 941-X (Adjusted Employer's Quarterly Federal Tax Return). Provide a copy of your I-20 and explain the F-1 exemption.
3. If employer refuses or cannot help, file Form 843
Submit IRS Form 843 ('Claim for Refund and Request for Abatement') with: (a) copy of W-2, (b) Form 8316 or written statement, (c) copy of I-20, (d) visa stamp copy, (e) I-94 arrival record, (f) letter explaining you are exempt under IRC § 3121(b)(19).
4. Mail Form 843 to the IRS
Send to the IRS service center where your employer files their 941 (check Form 843 instructions). Processing takes 6–12 weeks. You have up to 3 years from the filing deadline to claim the refund.

7. Tax Treaty Benefits by Country
The US has income tax treaties with over 65 countries, and many include special provisions for students and trainees. These benefits are not automatic — you must claim them on your tax return using Schedule OI (Other Information) on Form 1040-NR and, for wages, by submitting Form 8233 to your employer. Check our glossary for treaty-related terms.
| Country | Treaty Article | Exemption | Applies To |
|---|---|---|---|
| India | Article 21(d) | $5,000/year | Wages, scholarships, fellowships |
| China | Article 20(c) | $5,000/year | Wages from employment |
| South Korea | Article 21(1) | $2,000/year | Personal services income |
| Japan | Article 20 | Entire scholarship | Scholarships & fellowships only |
| Germany | Article 20(4) | $9,000/year | Employment & self-employment |
| France | Article 21 | $5,000/year | Personal services |
| United Kingdom | Article 20 | Entire scholarship | Scholarships & government grants |
| Canada | Article XV | No student-specific provision | General employment rules apply |
| Mexico | Article 20 | Entire scholarship | Government scholarships only |
| Brazil | No treaty | N/A | No US-Brazil income tax treaty in force |
| Russia | Article 18 | Entire scholarship | Scholarships & government grants |
| Australia | Article 20 | Entire scholarship | Scholarships & fellowships |
| Pakistan | Article XII | $5,000/year | Personal services income |
| Bangladesh | Article 21 | $5,000/year | Personal services |
| Philippines | Article 22 | Entire scholarship | Scholarships only |
Important: Treaty benefits must be actively claimed on your tax return. Consult IRS Publication 901 for the full list of treaties. Treaty provisions change — always verify current terms. Students from India should note that the US-India treaty also permits claiming the standard deduction on Form 1040-NR.
8. State Tax Filing for F-1 Students
In addition to federal taxes, most US states require you to file a state income tax return if you earned income in that state. State filing rules vary widely — here is what F-1 students need to know.
States With No Income Tax
If you live and work in one of these states, you do not need to file a state income tax return:
*New Hampshire and Tennessee only tax investment income (dividends and interest), not wages.
States With Special Rules for NRAs
California: Requires Form 540NR. CA taxes all income earned in the state. NRA students cannot claim the CA standard deduction.
New York: Requires Form IT-203 (Non-Resident/Part-Year). NY taxes income earned in the state and allocates based on days present.
Massachusetts: Requires Form 1-NR/PY. MA taxes all income earned in the state at a flat 5% rate.
Illinois: Requires Form IL-1040. IL has a flat 4.95% income tax. NRA students file as non-residents.
Pennsylvania: Requires Form PA-40. PA has a flat 3.07% rate. Relatively straightforward for NRAs.
Sprintax supports state tax returns for 44 states. Check your university's international student office — many provide free state tax filing assistance through VITA programs or Glacier Tax Prep.
9. Sprintax vs TurboTax: Which Should F-1 Students Use?
This is one of the most important decisions F-1 students face during tax season. Using the wrong software can result in filing the wrong form entirely. Here is a detailed comparison.
| Feature | Sprintax | TurboTax | Glacier Tax Prep |
|---|---|---|---|
| Supports 1040-NR (NRA) | Yes | No | Yes |
| Supports 1040 (Resident) | No | Yes | No |
| Form 8843 generation | Yes | No | Yes |
| Tax treaty benefits | Auto-detects | Not applicable | Auto-detects |
| State returns | 44 states ($39.95 extra) | All states | Limited |
| Federal return cost | $49.95–$69.95 | $0–$89 | Free (via university) |
| E-file available | Yes (federal) | Yes | No (paper only) |
| FICA refund guidance | Yes | No | No |
| Live chat support | Yes | Yes (paid tier) | No |
| Best for | Non-resident aliens (NRA) | Resident aliens / US citizens | Simple NRA returns |
TurboTax Does NOT Support Non-Resident Alien Filing
TurboTax, H&R Block, FreeTaxUSA, and Cash App Taxes only generate Form 1040. They do not support Form 1040-NR. If you are a non-resident alien and use TurboTax, you will file the wrong form — which can trigger IRS audit notices and create immigration complications.
Our Recommendation
If you are a non-resident alien (most F-1 students in their first 5 years): use Sprintax. It is purpose-built for NRA tax filing, auto-detects treaty benefits, generates Form 8843, and supports e-filing. If your university offers Glacier Tax Prep for free, that is a solid option for simple returns. Use the TrackMyOPT Tax Tool to determine your residency status first.
10. Common Tax Mistakes F-1 Students Make
After helping thousands of international students, these are the most frequent — and most costly — tax filing errors we see. Each mistake includes the real-world consequence and how to fix it.
1. Filing as a resident alien using TurboTax or H&R Block
Consequence: Files Form 1040 instead of 1040-NR. IRS may issue a notice, you may owe back taxes, and your immigration record shows an incorrect filing status.
Fix: Use Sprintax or Glacier Tax Prep. If you already filed incorrectly, file an amended return (Form 1040-X to undo the 1040, then file a correct 1040-NR).
2. Forgetting to file Form 8843 (no income, so nothing to file)
Consequence: Creates a gap in your IRS record. Can complicate green card applications, H-1B petitions, and future status changes. USCIS and immigration attorneys may flag this.
Fix: File Form 8843 retroactively for every year you were present in the US. There is no penalty for late filing, but do it as soon as possible.
3. Not claiming the FICA tax refund
Consequence: You lose 7.65% of your gross wages. On $30,000 of income, that is $2,295 left on the table.
Fix: Check W-2 boxes 4 and 6. If amounts were withheld, request a refund through your employer or file Form 843.
4. Claiming the standard deduction as a non-resident alien
Consequence: NRAs cannot claim the standard deduction (with limited treaty exceptions for Indian citizens). The IRS may adjust your return and assess additional tax.
Fix: Only claim itemized deductions or treaty-based deductions. Indian students can claim the standard deduction under Article 21.
5. Not reporting taxable scholarship income
Consequence: Scholarship amounts exceeding qualified tuition and required fees are taxable. Unreported income can trigger IRS notices.
Fix: Calculate: Total scholarship minus qualified tuition/fees = taxable portion. Report on 1040-NR.
6. Missing tax treaty benefits
Consequence: You pay more tax than legally required. For Indian or Chinese students, this could be $5,000+ of unnecessary tax.
Fix: Check if your country has a treaty (see Section 7). Claim benefits on Schedule OI of 1040-NR. Submit Form 8233 to your employer for wage exemptions.
7. Forgetting to file state tax returns
Consequence: State revenue departments can assess penalties and interest. Some states are more aggressive than others (California, New York).
Fix: If you earned income in a state with income tax, you must file a state return. Sprintax supports 44 states.
8. Filing with the wrong SSN/ITIN or not having one
Consequence: Returns processed without an SSN/ITIN are delayed. You cannot e-file without one.
Fix: Apply for an ITIN using Form W-7 if you don't have an SSN. You can submit W-7 with your tax return.
9. Ignoring the 1042-S from your university
Consequence: The 1042-S reports scholarship/fellowship income that was subject to withholding. Not reporting it means you cannot claim the withheld amount as a credit on your return.
Fix: Contact your university's payroll office if you haven't received your 1042-S by mid-March.
10. Waiting until the last day to file
Consequence: Tax software crashes, postal offices are packed, and you may miss errors that need correction. Extensions are free to file.
Fix: Start gathering documents in January. File by mid-March. If you need more time, file Form 4868 for an extension to October 15.

Frequently Asked Questions
Do F-1 students pay taxes in the US?
Yes. All F-1 students who earn US-source income must pay federal income tax (and usually state income tax). Even students with zero income must file Form 8843. Non-resident aliens file Form 1040-NR instead of the standard 1040.
What happens if I don't file Form 8843?
There is no immediate IRS penalty for not filing Form 8843. However, failing to file can create complications for future visa applications, green card petitions (I-485), H-1B transfers, and USCIS status changes. Immigration attorneys strongly recommend filing it every year.
Can F-1 students use TurboTax to file taxes?
No — not if you are a non-resident alien (most F-1 students in their first 5 years). TurboTax only generates Form 1040, not Form 1040-NR. Using TurboTax as an NRA means filing the wrong form. Use Sprintax or Glacier Tax Prep instead.
How do I know if I am a resident or non-resident alien?
F-1 students are classified as 'exempt individuals' for their first 5 calendar years in the US. During this period, you are a non-resident alien (NRA) for tax purposes. After 5 calendar years, you take the Substantial Presence Test to determine your status.
What is the FICA tax exemption and how much can I save?
FICA includes Social Security (6.2%) and Medicare (1.45%) — combined 7.65% of wages. F-1 students are exempt during their first 5 calendar years under IRC § 3121(b)(19). On $50,000 of annual wages, this saves $3,825. If FICA was incorrectly withheld, you can claim a refund.
When is the tax filing deadline for F-1 students?
For the 2025 tax year: April 15, 2026 if you have US-source income. June 15, 2026 if only filing Form 8843 with no income. You can request an extension to October 15, 2026 using Form 4868, but any taxes owed are still due by April 15.
Do I need to file state taxes as an F-1 student?
If you earned income in a state with income tax, yes. States like Texas, Florida, Washington, Nevada, and several others have no income tax. For states that do, you'll need to file a non-resident state return. Sprintax supports 44 states.
What is a tax treaty and do I qualify?
A tax treaty is an agreement between the US and another country that can reduce or eliminate tax on certain types of income. Many treaties include student-specific provisions. For example, Indian students can exempt $5,000 of income under Article 21(d), and Chinese students can exempt $5,000 under Article 20(c).
Can I get a refund if my employer withheld FICA taxes?
Yes. First, ask your employer's payroll department to correct the error and refund the FICA taxes. If they cannot or will not, file IRS Form 843 with copies of your W-2, I-20, visa stamp, and a letter explaining your F-1 exempt status. Processing takes 6-12 weeks.
What is the difference between Form 1040 and Form 1040-NR?
Form 1040 is for US citizens and resident aliens — it taxes worldwide income and allows the standard deduction, education credits, and all filing statuses. Form 1040-NR is for non-resident aliens — it taxes only US-source income, generally does not allow the standard deduction, and limits filing status to Single or Married NRA.
