You’ve just received a W-2 form in the mail or email from your U.S. employer. A W-2 is the official form that reports your wage income and the taxes your employer withheld during the year. If you’re a J-1 visa holder who worked in the U.S., this form is the starting point for your tax return. But what exactly do you do with it, and how does it fit into your filing? This guide walks you through the steps in the exact order you’ll need to take them—from the moment you open that envelope to understanding what happens next.

Before you start — what you need on hand

Gather these documents before you begin. You’ll need your W-2 form itself, your passport or visa stamps showing your J-1 status and entry/exit dates from the U.S., and any prior-year U.S. tax returns you may have filed. If you received any other income (interest from a bank account, for example), pull those statements too. Having everything in one place saves time and helps you spot potential issues early.

Step 1: Check your W-2 for accuracy

Open your W-2 and verify every detail. Your name, Social Security Number or Individual Taxpayer Identification Number (ITIN—a tax ID for nonresidents who don’t have an SSN), and address should match your records exactly. Look at Box 1, which shows your total wage income for the year. Check Box 2, which shows federal income tax withheld, and Box 4, which shows Social Security tax withheld. Also confirm your employer’s name and address are correct.

If anything is wrong—a misspelled name, incorrect income amount, or wrong withholding—contact your employer’s payroll or HR department immediately and ask for a corrected W-2. They must issue a corrected form within a reasonable time. Don’t proceed with filing until you have the correct version.

Step 2: Determine your residency status under the Substantial Presence Test

Your residency status determines which tax form you file. The Substantial Presence Test is the IRS rule that determines whether you are a nonresident or resident alien for tax purposes. The test counts your physical presence in the U.S. over multiple years, but J-1 visa holders in certain categories can exclude some of those days. If you are a “student” category J-1, you can exclude U.S. presence from the test for up to 5 calendar years. If you’re in a “teacher or trainee” category (including interns, trainees, camp counselors), you can exclude 2 of the last 6 calendar years in most cases. Once your exclusion period ends and you meet the test, you become a resident alien and file Form 1040 instead of Form 1040-NR.

Use the Substantial Presence Test tool to check your specific status based on your visa category and arrival date. Your residency status affects which form you file and how much of your income is taxable.

Step 3: Understand whether FICA taxes were withheld correctly

Look at your W-2, Box 4 (Social Security) and Box 6 (Medicare). These are FICA taxes. In general, if you are a nonresident alien on a J-1 visa in your first year, you should be exempt from Social Security and Medicare tax, and your employer should not have withheld these amounts. However, this depends on your specific visa category, prior time in the U.S., and whether your home country has a tax treaty with the U.S. Some employers incorrectly withhold these taxes even when they shouldn’t. If you see withholding in these boxes and you believe you were exempt, note it—you may be able to reclaim it when you file.

Step 4: Gather information about your J-1 status and Form 8843

You will need to file Form 8843, Statement for Exempt Individuals, if you qualify as a nonresident alien and want to claim the student or teacher/trainee exemption from the Substantial Presence Test. This form goes alongside your tax return and tells the IRS why certain days of your U.S. presence don’t count toward the Substantial Presence Test. Write down the exact dates you entered and left the U.S. during each calendar year you were here. Your passport stamps or DS-2019 document from your program sponsor will have these dates.

Step 5: Decide which tax form to file

If you determined in Step 2 that you are a nonresident alien, you file Form 1040-NR, the U.S. Nonresident Alien Income Tax Return. If you are a resident alien, you file Form 1040, the standard U.S. Individual Income Tax Return. The quote from the IRS directly states: “J-1 aliens who are U.S. resident aliens for the entire taxable year must report their entire worldwide income on Form 1040, U.S. Individual Income Tax Return, in the same manner as if they were U.S. citizens.” Your form choice determines how you report your W-2 income and which deductions and credits you can claim.

Step 6: Enter your W-2 income on your tax return

On your chosen form (1040-NR or 1040), locate the section for wage and salary income. You will report the amount from your W-2, Box 1 (your total wages). This goes on the income lines of your return. The federal withholding shown in Box 2 of your W-2 also goes on your return—it counts as a tax payment you’ve already made to the IRS, which reduces what you owe or increases your refund.

Step 7: Check for state income tax filing requirements

State tax rules vary significantly. Some states do not have a personal income tax, so you owe nothing at the state level. Others tax wage income at a flat or graduated rate and require you to file a return. Your employer may also have withheld state income tax, shown separately on your W-2 or paystub. Research whether the state where you worked has an income tax and whether you meet the filing threshold. If you owe state tax, file the required state return and report your W-2 income there as well, claiming any state withholding you made.

Step 8: File your federal return by the deadline

Once you have all your documents, your Form 8843 (if applicable), and your chosen form (1040-NR or 1040) completed, file it with the IRS before the filing deadline. You can file electronically through a tax preparer, tax software, or by mail if you prefer. Keep a copy for your records. If you filed correctly and your employer withheld more tax than you owe, you will receive a refund.

Handling state tax differences

The way states treat J-1 visa holders varies. Some states follow federal residency rules; others have their own definitions. A few states offer special exemptions or lower tax rates for certain visa holders. Because you may have worked in a state with no income tax, a flat tax, or a graduated system, check the specific rules for any state where you earned income. If you owe state tax, filing early protects you from penalties and interest.

Frequently Asked Questions

Can I file my taxes before I receive my W-2?

No, you should wait until you have your W-2 in hand. Your employer is required to send or make available your W-2 by January 31 each year. Filing without it means you won’t have the exact income and withholding figures, which will likely trigger an IRS correction request later. Wait for the form, verify it, then file.

What happens if my employer doesn’t send me a W-2?

If your employer has not sent your W-2 by mid-February, contact them directly and ask for it. If they refuse or you cannot reach them, you can file Form 4852 (Substitute for Form W-2) with your tax return and explain the situation to the IRS. Include copies of your paystubs or any other wage documentation you have. The IRS will investigate the missing W-2.

Do I file both Form 1040-NR and Form 8843?

If you are a nonresident alien claiming an exemption under the Substantial Presence Test (because you’re a student or teacher/trainee J-1), you file both forms together—Form 8843 and Form 1040-NR. The Form 8843 explains your exemption and your visa category; the Form 1040-NR reports your income and withholding. If you are a resident alien, you file only Form 1040.

I think FICA taxes were withheld incorrectly. What do I do?

Note the Social Security and Medicare withholding amounts shown in your W-2 (Boxes 4 and 6). If you believe you were exempt and should not have paid these taxes, report this on your return or include a note explaining your exemption claim. Many nonresident J-1 workers discover this issue during filing; the calculator can help you identify it and estimate any refund owed.

What if I worked in two states during the year?

Your W-2 will show total federal income and federal withholding. However, state withholding and state filing requirements are tied to where you worked. If you worked in two states, you may owe taxes in both or in only one, depending on their rules. Check each state’s requirements and file returns where necessary. State tax treatment of J-1 holders varies, so research each state’s threshold and rate.

This is general information, not personalized tax advice. Your exact situation depends on your visa history and paperwork—use the calculator for a number based on your own details, and consult a qualified tax preparer for anything beyond a standard return.

Your W-2 is the foundation of your J-1 visa tax return—verify it, determine your residency status, and use it to report your income accurately. Whatever your specific circumstances around your J-1 visa taxes, running your W-2 and income details through the tax calculator gives you a personalized estimate of what you owe or what refund you can expect. File on time, keep copies, and you’re done.
