You worked the first half of the year in one state and moved to another—now you’re staring at your tax form wondering which state to list. This is one of the trickier parts of filing as a J-1 visa holder, because the IRS doesn’t always want the state where you ended the year, and state tax departments don’t always agree with each other about who owes what. The good news: the rule is consistent and learnable, and once you know it, you won’t second-guess yourself.

Which state do you claim on your J-1 tax return if you moved?

You claim the state where you were a resident for the entire year—which is usually the state where you spent the most time, or where you had a permanent home, or both. If you moved mid-year, you typically file a nonresident return in the state you left and a resident return in the state you moved to (if that state requires it). The key word is “resident”: it’s not about where you ended up, it’s about your residency status in each state during the time you were there.

For federal tax purposes, your Form 1040-NR or Form 1040 reports your nationwide U.S. income, regardless of which states you lived in. State returns are separate—you’ll file in each state where you owed tax during the year, based on that state’s rules for residency and nexus (which means whether the state claims the right to tax you based on where you earned the income or lived).

It depends on your time in each state, your visa category, and that state’s rules

The reason this feels ambiguous is that each state defines residency differently, and your J-1 category affects how the federal government sees your residency status. Here’s what matters:

Your J-1 category (student, teacher, trainee, intern, etc.): Student-category J-1s have a special break under federal tax rules—they can exclude their time in the U.S. from the Substantial Presence Test for up to 5 calendar years. Teacher and trainee category J-1s can exclude 2 of the last 6 calendar years (sometimes extendable to 4). This matters for your federal residency status, but it does *not* automatically exempt you from state tax—each state sets its own rule. Some states tax nonresidents who earned income within their borders, regardless of federal status.

How long you lived in each state: If you spent January through June in State A and July through December in State B, you were a resident of State A for the first half and State B for the second half. State A may want to tax your income earned there (roughly half your year’s wages) and may require a part-year return. State B will want to tax your income earned there and may require a resident return.

Each state’s nonresident/part-year rules: Some states have no income tax at all—no return needed. Others tax nonresidents on income earned within their borders. Still others only tax residents. A few offer resident and nonresident statuses, and some recognize part-year resident status if you moved during the year. You may need to file in one, two, or even more states depending on where you worked and where you lived.

Your home country tax treaty (if one exists): If your home country has a tax treaty with the U.S., certain provisions might affect how much state tax you owe or whether you qualify for an exemption. This is rare and depends on your specific country and treaty language, but it’s worth checking if you’re from a major treaty partner nation.

Where people get this wrong

Mistake 1: Filing only in the state where you ended the year. You’ll see this one a lot—people assume “I’m in State B now, so I file there.” That’s not how it works. If you earned significant income in State A, State A will expect a return or at least notice that you owe tax on that income. Skipping State A’s return can lead to a notice or audit, especially if the states compare notes through data-sharing systems.

Mistake 2: Assuming your federal residency status automatically determines your state tax status. You might be a nonresident alien for federal purposes (maybe this is your first year on a J-1, or your category excludes you from the Substantial Presence Test), but your state might still tax you. Federal nonresident status does not equal state nonresident status. They’re independent questions, and states don’t care what the IRS decided about your federal residency.

Mistake 3: Forgetting that income tax is usually owed where the income was earned, not where you lived when you earned it. If you worked in State A in March earning $2,000, you owe State A income tax on that $2,000 even if you moved to State B in May. The IRS and most states care about where the income was *earned*, not where you were living when you filed.

Frequently Asked Questions

Do I file in both states if I moved mid-year?

In most cases, yes—you’ll file a return in each state where you owed income tax during the year. If State A had income tax and you earned money there before moving, you’ll file a part-year or nonresident return in State A. If State B had income tax and you earned money there after moving, you’ll file a resident or part-year return in State B. Some states have no income tax, so you won’t file there at all. The calculator helps you work through your specific states and the income you earned in each one.

If I moved in July, do I claim my whole year as State B resident?

No. You claim yourself as a resident of State B only for the part of the year you actually lived there as a resident (usually July onward in your example). For January through June, you were a resident of State A, and you owe tax on income earned in State A during that time according to State A’s rules. Some states call this “part-year resident” status, meaning you were a resident for only part of the year.

What if one of my states had no income tax?

Then you don’t file a return there. If you moved from a state with no income tax to a state with income tax, you only file in the state with income tax (for the months you lived there). If you moved from a state with income tax to a state with no income tax, you file a part-year or nonresident return in the first state, and nothing in the second state—though the second state may ask you to confirm you’re not a resident, depending on its rules.

Does my federal residency status (Form 1040 vs. 1040-NR) determine which state form I file?

No. Your federal tax form (1040 or 1040-NR) is separate from your state tax forms. You might be a nonresident alien for federal purposes but still owe state income tax on earnings in a particular state. Conversely, you might be a federal resident alien but owe part-year or nonresident state tax if you moved. Each state has its own definition of residency and sets its own rules about who pays tax and when.

Who decides if I’m a “resident” of a state for tax purposes?

Each state does. There’s no single federal definition of state residency for tax purposes. Most states look at factors like where you lived, whether you had a permanent home, where you worked, and how long you stayed. Some states have bright-line rules (e.g., 183 days in the state makes you a resident). Others weigh a mix of factors. Your state government’s tax or revenue department publishes its rules—that’s your source of truth for your state.

This is general information, not personalized tax advice. Your exact situation depends on where you worked, where you lived, your J-1 category, and each state’s specific rules. Use the calculator to see your estimated federal refund or tax bill, and consult your state’s revenue department or a qualified tax preparer for state-specific questions.

You moved during the year, and that means filing across state lines—but the principle is simple: claim tax residency where you actually were a resident, and file in each state where you earned income or owed tax. Once you run through your paystubs and confirm where each dollar was earned, the filing gets straightforward. The fastest way to see your real J-1 tax refund number and understand which state forms you’ll need is to answer a few quick questions in the calculator and let it walk you through your specific situation.
