You spent part of your J-1 placement in one state and part in another. Now you’re wondering: do you file two tax returns? Do you report all your income on one federal return? Which states want a cut of your earnings? Working across state lines as a nonresident alien adds complexity, but it’s manageable once you understand the basic rules. This guide walks you through how to handle your multistate J-1 income step by step, so you don’t miss a filing requirement or overpay.

How to file your tax return when you worked in two states

Yes, you file one federal tax return (Form 1040-NR or Form 1040, depending on your residency status), but you may owe state income tax to both states where you earned money. Each state taxes income earned within its borders—even if you’re not a state resident and even if you’re a nonresident alien for federal purposes. You’ll likely need to file a state return for each state that had income and that state’s rules say you must file. Some states don’t have income tax at all, which simplifies things for you; others do tax wages at a flat or graduated rate and will require a return.

What determines which form you file federally and whether states have a claim on your income

Your residency status under the Substantial Presence Test is the biggest factor. If you’re a nonresident alien for federal tax purposes, you file Form 1040-NR, and you report only U.S. source income. If you’ve met the Substantial Presence Test—which depends on your J-1 category (student vs. teacher/trainee), how long you’ve been in the U.S., and years you can exclude from the count—you become a resident alien and file Form 1040, reporting worldwide income.

Which states have a tax claim on you depends on where you actually earned the income, not where you’re considered a resident. A student J-1 from any country who earned wages in State A from June to August and then moved to State B for September still owes both states income tax on their respective earnings. State tax rules can vary significantly: some states exempt nonresidents entirely, others tax all income earned within the state, and a few offer tax treaties or exemptions for certain visa categories. Your J-1 category, prior time in the U.S., and your home country’s tax treaty with the U.S. all play a role in whether you qualify for any exemptions.

Where this gets wrong most often

The most common mistake is reporting your income to only one state—usually the state where you filed, not realizing the second state also has a legal claim. Each state tracks wage income independently through W-2 filings, so the state you skip filing in will eventually notice the unreported W-2. Another frequent mix-up is assuming that because you’re a nonresident alien, you don’t owe state income tax; that’s false. Nonresident status for federal purposes doesn’t exempt you from state tax—you still owe the state where you worked, regardless of visa type. Finally, some J-1 workers underestimate tax withholding differences between states. One state might have withheld correctly; the other might have withheld too much or too little. Unless you check both W-2s against the rules of each state where you worked, you could miss a refund or owe money you didn’t anticipate.

Frequently Asked Questions

If I worked in two states, do I file two W-2s?

You don’t file W-2s—your employers do. If you worked for two different employers (one in each state), you’ll receive two W-2 forms, one from each employer showing the wages paid and taxes withheld by that employer. If you worked for the same employer but the employer had offices in both states, you might get one W-2 broken down by state, or two separate W-2s. Either way, all W-2s are due to you by January 31 each year.

Which state do I file my state return with first?

There’s no required filing order, but you’ll typically file with your “home state”—the state where you have primary residence—first if you lived there longer. However, as a J-1 on a temporary visa, you may not have a state resident status anywhere. In that case, file with the state where you earned the most income or where you spent the most time. What matters most is that you file with both states that had income, even if you file one after the other. Both states will independently confirm that you owe tax based on your W-2.

What if one state has no income tax?

Then you don’t file a state return in that state. Nine U.S. states have no income tax at all. If you worked in one of those states and another state that does tax income, you file only for the state with an income tax. Confirm which states fall into this category—the list can shift, and some states exempt nonresidents under specific conditions. The state revenue department website for each state will clarify whether you must file.

Can I claim a credit on one state return for taxes paid to the other state?

Yes, most states allow a foreign tax credit or interstate tax credit if you paid income tax to another state on the same income. However, the rules vary by state—some states are more generous than others. Generally, you’ll report the tax paid to the first state as a credit on the second state’s return, but only up to what the second state would have owed. This prevents double taxation, but it requires filing both returns and tracking what you paid in each state.

Do I need to file before April 15, or is the J-1 deadline different?

J-1 visa holders have the same federal filing deadline as everyone else: typically April 15 of the following year. However, you can request an extension for a few additional months if needed. State deadlines also generally align with the federal deadline, though a few states differ slightly. The IRS announces the exact filing season opening date each year—check the IRS website or the calculator for the current dates to avoid confusion.

Important note on your specific situation

This is general information, not personalized tax advice. Your exact residency status, state tax obligations, and refund eligibility depend on your visa history, J-1 category, and the states where you worked. Use the tax calculator to run your real numbers based on your own W-2s and situation, and consult a qualified tax preparer if you’re unsure about your state filing requirements or eligibility for exemptions.

Handling a multistate J-1 return correctly comes down to understanding that federal and state taxes are separate—you owe federal tax based on your residency status, and you owe state tax based on where you earned income. Whatever your specific breakdown across two states, the fastest way to see your real refund on your J-1 visa taxes is to plug your W-2s into the calculator and get a personalized estimate. File with both states, claim any available interstate credits, and you’ll be in the clear.
