How to File Taxes in Two States After Moving

When you move from one state to another mid-year, each state may require a part-year resident tax return. You report only the income earned while living in that state on each return. If one state has no income tax, you may only need to file in the other. Tax credits generally prevent double taxation on the same income.

Moving to a new state mid-year often raises a straightforward question: do you now have to file taxes in two states?

The answer is often yes. If you move from one state to another during the tax year, there's a good chance you'll end up filing tax returns in both your old state and your new state as a part-year resident. It comes down to where you lived, when the move happened, and whether both states impose income tax.

Here are the ins and outs.

Quick Reference: Do You Need to File in Two States?

What Part-Year Residency Means for State Taxes

Part-year resident means you lived in a state for only part of the tax year — for example, if you moved from Illinois to Texas in June.

Here's what happens when you move from State A to State B partway through the year. You become a part-year resident of both. State A counts you as a resident for however long you lived there. State B picks up where that left off.

The split happens based on your residency status, not whatever state you happened to be in on December 31st. So even if you're settled in your new state by year-end, your old state may still tax income you earned while you were living there.

Most states require part-year residents to file a part-year tax return that reports only the income earned while living in that state. The whole point is to prevent double taxation by splitting the same income between two returns based on when and where you actually earned it.

When Two State Returns Are Required

If you moved mid-year and both states impose income tax, you'll likely need to file taxes in two states.

The basic logic goes like this: earned income in a state where you lived for part of the tax year? That state typically wants a return. Most states with state income tax set a filing threshold, and if your income during the time you lived there crosses that line, you may need to file taxes. You may also need to pay taxes to both states, though credits help prevent double taxation.

Your tax liability in each state generally depends on what income you earned during your residency period, plus that state's tax laws.

Income Earned in Multiple States

Say you lived in Pennsylvania from January through June, then moved to North Carolina. You'd likely file a part-year state income tax return in both states. Pennsylvania's return covers January through June. North Carolina's covers July through December.

If you work remotely, your tax obligations may differ — that's a separate topic.

Common Triggers for Dual Filing

You're likely to file state taxes in two states if:

• You worked in both states during the year
• You earned rental income from rental property or business income in your former state
• You received bonuses or severance tied to your old state after moving
• Both states have income taxes and your income crossed their filing thresholds

States generally determine residency status by looking at where you kept your primary home, how much time you spent in each place, and what your intent was. Once you've established residency in your new state, your old state will usually consider you a nonresident. But you may still owe taxes or need to pay income tax on income earned there before you left.

Common Filing Scenarios

Here are the situations people run into most often:

Moving Between Two Income Tax States

You lived in North Carolina for seven months, then moved to Virginia. You'll likely file a part-year state income tax return in North Carolina covering income earned from January through July, and a part-year return in Virginia covering income earned from August through December.

Moving to a State Without Income Tax

You lived in New York for six months, then moved to Florida. You'll file a part-year tax return in New York for the time you lived there. Florida typically won't require anything because it doesn't have state income tax.

Moving From a State Without Income Tax

The opposite works similarly. You lived in Texas for four months, then moved to Colorado. Texas doesn't impose state income tax, so you typically wouldn't file there or pay taxes to Texas. You'd file a part-year resident return in Colorado covering the months after your move.

Moving Back to Your Original State

This one's a bit messier. You started the year in Ohio, moved to Michigan partway through, then came back to Ohio before the year ended. You're still filing taxes in two states. Ohio gets a return covering two separate periods. Michigan gets a return for the middle stretch.

Moved Mid-Year but Kept a Job in Your Old State

If you moved but continued working for an employer located in your old state, that state may still tax income sourced there. In some cases, you may need to file a nonresident return in your former state for income earned after your move. Filing requirements depend on that state's sourcing rules and whether your income exceeds its filing threshold.

Military Moves and State Tax Filing

If you're an active-duty service member, different rules may apply to your state tax residency during a PCS move — state residency rules for military personnel vary.

Military personnel usually file a tax return for their state of legal residence, known as their Home of Record, rather than one in the state where they are stationed. In fact, federal law does not allow States to tax military wages earned by nonresident military members stationed in their state.

When Only One State Return May Be Needed

Not every move means dealing with state taxes in two locations at tax time.

If either your old state or new state doesn't have income tax, you typically won't pay state income taxes to that one. States like Florida, Texas, and South Dakota make this easy.

There are other scenarios too. Maybe you moved before earning any income in your new state, or you stopped earning income before leaving your old state. In cases like that, you might only need to file a tax return in whichever state you actually had taxable income.

Reciprocal Agreements Between States

Some states have what are called reciprocal agreements (or reciprocity agreements) with their neighbors. Under these setups, if you live in one state but work in another state, you might not need to file a tax return in your nonresident state. Employees must file an exemption form in the state where they work to avoid state income tax withholding.

Reciprocal agreements typically apply to commuters, though, not people who actually moved. If you changed where you legally live during the year, you'll probably still need to file as a part-year resident in both states.

Do I Need to File a Final Return in My Old State?

There is no "final" state tax return. You file a part-year resident return covering the period you lived in that state.

A part-year tax return documents your residency period and the income you earned while living there during that tax year. If you move back later, you'd just file as a resident again.

Most states don't require special notification when you leave. Filing your part-year return and updating your address with state agencies is typically sufficient. Some states might keep sending tax forms to your old address, so updating your address with your old state's tax department can help you avoid missing notices.

What About Federal Taxes?

Your federal income tax return covers all your income for the entire tax year no matter where you lived. Moving states doesn't change your federal filing requirements, just the state tax situation.

The Part-Year Filing Workflow

Here's the typical order of operations:

1. File your federal Form 1040 first — it covers the whole year and isn't split
2. Determine move date — establish the exact day you became a resident of the new state
3. Allocate income by state — income earned while in State A goes on State A's return; income earned while in State B goes on State B's return
4. File State A part-year return — covering income from Jan 1 through move date
5. File State B part-year return — covering income from move date through Dec 31
6. Claim credits where needed — if any income was taxed by both states (e.g., due to residency-sourcing conflicts), claim a credit on the appropriate return

Both state returns reference your federal AGI as a starting point, then adjust for what's attributable to each state.

How Tax Credits Prevent Double Taxation

When you file taxes in two states as a part-year resident, most states offer ways to avoid double taxation. If both states are trying to tax the same income, your new state may offer tax credits for taxes paid to your old state.

You claim this credit for taxes paid to other states on your resident return in your new state. Those tax credits help reduce your overall tax liability during the transition period. Learn more from our State Tax Credits for Taxes Paid guide.

Final Thoughts on Multi-State Tax Filing

This is manageable. Track when you moved, document when you earned income in each state, and file the appropriate part-year tax return in both locations. Credits for taxes paid to other states help prevent double taxation, so filing in multiple states doesn't necessarily mean paying more in total taxes.

There's extra paperwork involved, but plenty of people navigate this every year. With decent records and a basic understanding of how residency rules work, you'll get through it just fine.
