The First Tax Return Guide for International Students in U.S

Nobody told you about this part.

You arrived in the United States to study, navigated the visa process, enrolled in classes, and started building your academic life here. Then, in the first year, you encountered something no university brochure prepared you for: the U.S. tax system — and the discovery that you are legally required to file federal tax forms with the IRS, even if you earned absolutely no income while you were here.

IRS compliance can affect later immigration steps, including visa renewals, OPT history reviews, and green card processing. Missing your tax filing obligations as an international student is not just a paperwork issue. It is a compliance issue with real immigration consequences.

This guide explains exactly what you need to file, when you need to file it, what the forms mean, and what happens if you get it wrong — for tax year 2025, filed in 2026.

The First Question: Are You a Resident or Nonresident for Tax Purposes?

Your immigration status and your tax status are not the same thing. This distinction is the source of more confusion than almost anything else in international student tax filing.

For U.S. tax purposes, you are classified as either a resident alien or a nonresident alien — and the classification determines which forms you file, what income is taxable, and what deductions you can claim. This classification is entirely separate from your visa status or your immigration residency.

The Five-Year Rule for F-1 and J-1 Students

Under IRS rules, F-1, F-2, J-1, and J-2 visa holders are classified as exempt individuals for the first five calendar years they are present in the United States. As an exempt individual, you are automatically treated as a nonresident alien for tax purposes — regardless of how many days you spend in the country.

Most F-1 and M-1 students who were in the US during 2025 and have been here for five years or fewer are nonresident aliens for tax purposes. This is the default position for the vast majority of international students filing their first tax return.

What this means practically:

You file Form 1040-NR (Nonresident Alien Income Tax Return), not the regular Form 1040 that U.S. citizens and resident aliens use
You are taxed only on U.S.-source income — income earned in the United States. Your income from your home country, scholarships from your home country, and financial support from your family abroad are generally not taxable
You cannot claim the standard deduction (nonresident aliens are not eligible)
You may be eligible for itemised deductions including State and Local Taxes (SALT) and charitable contributions

When you might be a resident alien for tax purposes:
After your fifth calendar year in the United States, you may become a resident alien through the Substantial Presence Test — a formula based on counting days present in the U.S. across the current and prior two years. If you trigger resident alien status, you file a regular Form 1040 instead of 1040-NR. Your university’s international student office or a qualified tax preparer can help determine your status if you are approaching or past the five-year mark.

The Two Forms Most International Students Must Know

Form 8843: The Form You File Even With No Income

This is the most misunderstood filing requirement for international students. Form 8843 is required for all F-1 and J-1 visa holders regardless of income — even if you had absolutely no U.S.-source income during the year.

Form 8843 is not a tax return. It is a statement to the IRS confirming that you are an exempt individual — that you were present in the U.S. on an F or J visa and should not be counted under the Substantial Presence Test. Without it, the IRS has no official record of your exempt status, which can cause complications in future years and potentially affect immigration proceedings.

Who must file Form 8843:
Every F-1, F-2, J-1, and J-2 visa holder who was present in the United States during 2025 — regardless of whether they earned any income.

Deadline for Form 8843 (filed alone, no income):
June 15, 2026 — if you have no income to report and are filing Form 8843 on its own.

What you need to complete Form 8843:

Your name, U.S. address, and passport information
Your visa type and entry dates into the United States
Your Form I-20 (F-1) or Form DS-2019 (J-1)
Your DSO’s (Designated School Official) name and contact information — your international student office can provide this

Where to send Form 8843 (no income):
Mail to: Department of the Treasury, Internal Revenue Service Center, Austin, TX 73301-0215. Make a copy before sending and keep it with your important documents permanently.

Form 1040-NR: The Tax Return for Students With U.S.-Source Income

If you earned any income from U.S. sources during 2025 — wages from on-campus work, stipends, teaching or research assistantships, scholarship money above tuition and required fees, prizes, or any other U.S.-source payment — you must file Form 1040-NR in addition to Form 8843.

Deadline for Form 1040-NR:
April 15, 2026 for tax year 2025 income. File 1040-NR and attach Form 8843 together.

Documents you will need:

W-2 form: Provided by your employer for wages earned. Your employer should mail or electronically deliver this by late January 2026. If you do not have your W-2 from each employer, contact them immediately.
Form 1042-S: Issued by your university or institution for scholarship income, fellowship income, or income covered by a tax treaty. Your university’s payroll or international student office issues this.
Form 1099: Issued by banks for interest earned (1099-INT), by investment platforms for investment income (1099-DIV, 1099-B), or for other miscellaneous income. Check your bank account and any platforms where you hold money.
SSN or ITIN: Your Social Security Number (if you have one through employment authorisation) or Individual Taxpayer Identification Number. You do not need an SSN or ITIN just to file Form 8843, but you do need one to file Form 1040-NR for income.

What Income Is Taxable — And What Is Not

This is the area where international students most commonly over-report or under-report income. Understanding what is and is not U.S.-source income changes the amount you owe or your refund amount.

Taxable U.S.-Source Income for Nonresident Students

Wages from employment — on-campus jobs, OPT employment, CPT employment (if applicable and properly authorised)
Teaching assistantship (TA) and research assistantship (RA) stipends — the taxable portion above the tuition waiver
Scholarship or fellowship funds above qualified educational expenses — if a scholarship covers more than tuition, required fees, books, and supplies required for courses, the excess is taxable
Prizes and awards — competition winnings, academic awards with cash components
Interest from U.S. bank accounts — generally taxable for nonresident aliens at 30% (though many tax treaties reduce or eliminate this)

Generally NOT Taxable for Nonresident Students

Financial support from family abroad — money sent to you by parents or relatives from your home country
Foreign scholarship or fellowship income paid entirely by a foreign institution
Qualified scholarship amounts — the portion of a scholarship that covers tuition and required fees directly
Home-country income — wages or investment income earned entirely outside the United States

FICA: The Tax Most International Students Are Exempt From

FICA refers to Social Security and Medicare taxes — the payroll taxes that automatically appear as deductions on most Americans’ pay stubs.

F-1, J-1, M-1, and Q visa holders in nonresident alien status during their first five years are exempt from FICA taxes on wages earned from authorised employment. This exemption applies to on-campus jobs, CPT employment, and OPT employment during the first five years of F-1 status.

This is a significant financial benefit. FICA totals 7.65% of gross wages. If your employer is withholding FICA from your pay and you are in your first five years of F-1 status, you are entitled to a refund of those withholdings. Ask your employer’s payroll department to correct this, or claim the refund on your tax return.

Important: After your fifth year in the United States, FICA exemption ends if you become a resident alien for tax purposes.

Tax Treaties: The Benefit Many Students Miss

The United States has tax treaties with dozens of countries that reduce or eliminate U.S. tax on certain types of income for residents of those countries. For international students from treaty countries, this can mean partial or complete exemption from U.S. tax on scholarships, wages, or other income — sometimes for a limited number of years.

You must fulfill four criteria to claim a tax treaty benefit: You must be a nonresident for tax purposes (this is different than your immigration status). You must receive U.S. source income from salary or a scholarship. You must be on an F-1, J-1, or H-1B visa. And the treaty must specifically cover your situation.

Countries with student-specific treaty provisions include (but are not limited to): China, India, South Korea, France, Germany, Canada, the Netherlands, Philippines, Thailand, and many others. Each treaty has different terms, income limits, and time restrictions.

Your university’s international student office should have a list of applicable treaty provisions. Glacier Tax Prep and Sprintax — the two most widely used international student tax software platforms — both identify treaty benefits automatically based on your country of tax residence.

How to claim treaty benefits: Report treaty-exempt income on Form 1040-NR and attach Form 8833 (Treaty-Based Return Position Disclosure) if the exemption amount exceeds $10,000 in certain categories.

Getting Your ITIN: What It Is and When You Need One

An Individual Taxpayer Identification Number (ITIN) is a nine-digit tax processing number issued by the IRS to people who are required to file a U.S. tax return but are not eligible for a Social Security Number.

If you have no income and are only filing Form 8843, you do not need an ITIN. If you have U.S.-source income and need to file Form 1040-NR, you need either an SSN or an ITIN.

Applying for an ITIN:
Complete IRS Form W-7 and submit it with your completed tax return and original identification documents (passport) or certified copies. Submit simultaneously with your first tax return filing. You can also apply through a Certified Acceptance Agent — your university’s international student office can recommend options.

ITIN processing times vary but typically take 6–11 weeks. Apply early.

Deadlines Summary for Tax Year 2025 (Filed in 2026)

Situation	Form(s) Required	Deadline
Present in U.S. in 2025, no income	Form 8843 only	June 15, 2026
Present in U.S. in 2025, with income	Form 1040-NR + Form 8843	April 15, 2026
Need more time for income return	File Form 4868 (extension)	April 15, 2026 (extends return to Oct 15)
Form 8843 alone (no income extension needed)	Form 8843	June 15, 2026 (no extension needed)

Critical note: A filing extension extends the time to file your return — it does not extend the time to pay any taxes owed. If you owe taxes, interest accrues from April 15 regardless of whether you filed an extension.

State Tax Returns: The Requirement Most Students Forget

Federal taxes are not your only obligation. Most states with income taxes require you to file a state tax return if you earned income in that state. Some states — including Florida, Texas, Washington, Nevada, Wyoming, South Dakota, Tennessee, and Alaska — have no state income tax. Most others do.

State tax returns are separate from federal returns and have their own forms, deadlines (usually April 15), and rules. Your university’s international student office can advise on state-specific requirements. Sprintax and Glacier Tax Prep both handle state returns for international students alongside the federal return.

Tools and Resources for Filing

Glacier Tax Prep: The most widely used tax preparation software for international students. Many U.S. universities provide it to their international students free of charge — check with your international student services office before paying for it yourself.

Sprintax: Another dedicated international student tax software. Charges $54.95 for Form 1040-NR preparation (as of 2026). Handles both federal and state returns. Some universities provide discount codes.

Your university’s international student office: Most ISOs have tax resources, guides, and clinic sessions during tax season. Some partner with VITA (Volunteer Income Tax Assistance) programs that offer free tax filing assistance.

What Happens If You Don’t File

Missing your filing obligations as an international student is not a minor error. The consequences are real and compound over time.

Penalties and interest. Failure to file a required return by the deadline results in penalties (5% of unpaid tax per month, up to 25%) and interest on any unpaid balance. Even if you owe no tax, failure to file Form 8843 creates a compliance record issue.

Immigration consequences. IRS compliance can affect later immigration steps, including visa renewals, OPT history reviews, and green card processing. Consular officers reviewing visa renewals and USCIS officers reviewing immigration benefit applications may ask for proof of tax compliance. Missing returns create documentation gaps that are difficult and costly to resolve.

Future complications. If you later apply for permanent residency or citizenship, your entire tax filing history is reviewed. Missing returns — even from years ago — must be resolved before immigration proceedings can be completed.

If you missed a prior year’s filing, the solution is to file as soon as possible. Late filing is always better than continued non-filing. A qualified tax professional can help you file late returns and minimise penalties.

The Bottom Line

Filing your first U.S. tax return as an international student feels overwhelming until you understand the framework. Most F-1 students in their first five years are nonresident aliens who file Form 8843 (required regardless of income) and Form 1040-NR (required if they earned any U.S.-source income). The tools exist — Glacier Tax Prep, Sprintax, and your university’s ISO — to make this manageable.

The deadline for income filers is April 15, 2026. Form 8843 alone is due June 15, 2026. File on time. Keep copies of everything. Understand your treaty benefits if applicable. And treat this annual obligation as the non-negotiable immigration compliance matter that it is.
