If you moved to another state, you generally have to pay state taxes to both states for the year of the move, then only to your new state going forward — unless you still earn income tied to the old one. Paying state taxes after moving to another state usually means filing a part-year resident return in each state for the transition year, and possibly a nonresident return in your former state for as long as you keep collecting rent, wages, or business income sourced there. Credits and, in some cases, reciprocity agreements keep the same dollar from being fully taxed twice, but only if you file correctly.
What You File in the Year You Move
Both states treat you as a part-year resident for the calendar year of your move, assuming both levy an income tax. You report income earned from January 1 through your move date on your former state’s return, and income from the move date through December 31 on your new state’s return. Most states publish a dedicated part-year resident form.
Do the former state’s return first. The tax you pay there feeds into the credit calculation on your new state’s return, and reversing the order creates rework.
Both returns are due by April 15 of the following year in most states. An extension gives you more time to file the paperwork but not more time to pay — any balance owed is still due by the original deadline, and missing it triggers penalties and interest.
Fix Your Withholding and Estimated Payments
If you’re a W-2 employee, submit a new W-4 to your employer so your paycheck reflects the correct state’s withholding. If you pay quarterly estimated taxes, redirect them to your new state after the move. Continuing to send estimated payments to a state you’ve left is one of the easier mistakes to make, and it can produce an underpayment penalty in your new state even while you’ve overpaid the old one.

When You Still Owe Your Old State After You Move
Your obligation to a former state doesn’t automatically end at the state line. If you continue earning income connected to that state — what tax authorities call source income — you’ll file a nonresident return there each year. Common categories include rental income from property you still own there, wages for work physically performed in the state, business income from a company that operates there, and gambling winnings from casinos or racetracks in the state.
As a nonresident, only the income sourced to that state is taxable, not your full income. Filing thresholds vary. Roughly half of the states with an income tax require a nonresident return if you earn any amount there; others set a dollar threshold or a minimum number of workdays before a filing obligation kicks in.
Retirement Income Is Off Limits to Your Old State
Federal law prohibits states from taxing the retirement income of nonresidents. Once you’ve moved out, your former state cannot reach your pension, 401(k) distributions, IRA withdrawals, 403(b) payouts, or government plan distributions.2Office of the Law Revision Counsel. 4 USC 114 – Limitation on State Income Taxation of Certain Pension Income The protection covers qualified retirement plan income paid as substantially equal periodic payments over your lifetime or over at least 10 years, and it includes military retired pay. Because the shield comes from a federal statute, it overrides whatever a state’s own source-income rules might say.
Domicile Versus Statutory Residency
A state can tax your income if it considers you a resident, and states use two separate tests: domicile and statutory residency. You can get caught by either one.
Your domicile is your permanent home — the place you intend to return to whenever you’re away. You can only have one at a time, and it doesn’t change simply because you spend months elsewhere. Domicile turns on intent, but states evaluate intent by looking at what you do, not what you say.
Statutory residency is mechanical. A majority of states treat you as a statutory resident if you maintain a home there and spend more than 183 days in the state during a tax year. This is the trap: you can be fully domiciled in your new state and still trigger statutory residency in the old one because you didn’t leave quickly enough or kept a residence available. When that happens, both states claim the right to tax your full income for the year.
Proving the Move If Your Old State Comes Looking
Changing your domicile requires both abandoning the old one and establishing the new one, and swapping a driver’s license while your actual life stays put isn’t enough. Actions that carry real weight:
- Getting a new driver’s license and vehicle registration in your new state
- Registering to vote and actually casting your ballot there
- Buying or leasing a home while selling or renting out your former residence
- Moving your valuable personal belongings — furniture, art, jewelry, family heirlooms
- Transferring relationships with doctors, dentists, accountants, and attorneys
- Updating your address with the IRS and all financial institutions
- Giving up residency-based benefits like resident hunting or fishing licenses and club memberships
No single action proves a domicile change. The pattern across all your actions matters more than any one step. A new license and voter registration look thin if your spouse, children, and family doctor are still in the old state. The strongest evidence is behavioral: where you sleep most nights, where your family lives, which airports you fly out of, and where you keep the possessions closest to you.
High-tax states audit people who claim to have moved away. If a state decides you never actually changed your domicile, it can assess back taxes plus interest and penalties for every year it still considers you a resident. The statute of limitations for a residency assessment runs three to four years from your filing date, though it extends indefinitely if you never filed. Interest accrues the entire time, with rates around 7% annually common. The burden of proof falls on you, so keep a log of days spent in each location, along with moving receipts, utility bills, and similar records.
People who hold onto a home in their former state face the toughest scrutiny. Auditors will question why you’re keeping a residence somewhere you supposedly no longer live. If you keep property there for any reason, track your days carefully. Crossing the 183-day statutory residency line while also claiming domicile somewhere else is the fastest way to lose a residency audit.
Avoiding Double Taxation
When two states tax the same income, your state of domicile generally lets you claim a credit for taxes paid to the other state. Nearly every state with an income tax offers this credit, and it’s the main mechanism preventing true double taxation.
The credit is capped at the lower of two amounts: what you actually paid the other state, or what your home state would charge on that same income. That cap has real consequences. If your former state charged $3,000 on rental income but your new state would only charge $2,000 on the same amount, your credit tops out at $2,000, and the extra $1,000 is gone. People moving from low-tax states to high-tax states usually get a full credit; people moving the other direction sometimes don’t.
To claim the credit, file the nonresident return with the other state first, then attach a copy of it and any required schedules to your resident state return.
Reciprocity Agreements for Cross-Border Commuters
Roughly 16 states and the District of Columbia participate in reciprocity agreements that simplify taxation for people who live in one state and commute to work in another. Under these agreements, you pay income tax only to the state where you live, and the state where you work agrees not to tax your wages.
This matters most if you moved to a state that borders your employer’s state but kept the same job. Without an agreement, your employer’s state withholds income tax from your paycheck, and you have to file a nonresident return there to recover it while also paying your home state. With an agreement, you file a withholding exemption form with your employer and your paycheck reflects only your home state’s tax.
Reciprocity agreements are bilateral, meaning they exist between specific pairs of states. Don’t assume coverage just because both states have deals with other neighbors. Check your specific pair before assuming you only owe tax in one place.
Remote Work and the Convenience of the Employer Rule
Remote work adds a wrinkle. In most states, if you work from home for an employer based in another state, you’re taxed where you physically do the work. But seven states — Connecticut, Delaware, Nebraska, New Jersey, New York, Oregon, and Pennsylvania — use a “convenience of the employer” test that can tax your wages based on where your employer’s office sits, not where you sit.3National Conference of State Legislatures. State and Local Tax Considerations of Remote Work Arrangements Several of these states limit the rule in significant ways, so check how your specific state applies it.
Under this test, if you work remotely for your own convenience rather than because your employer requires it, the employer’s state can tax your wages as if you commuted in every day. The main exception is necessity: if your employer mandated the remote arrangement or has no office space for you, the rule generally doesn’t apply.
The practical hit is real. If you moved out of one of these states but still work for an employer based there, that state may continue taxing your full wages, and your new home state will tax the same income as your state of residence. A credit usually offsets the overlap, but if your new home state has a lower rate, you effectively pay the higher state’s rate with no way to recover the difference.
Even outside the convenience-rule states, working remotely inside a state for more than a handful of days can trigger withholding obligations for your employer. Some state thresholds are as low as 14 or 15 days of physical presence in a calendar year.
If Your Move Involves a No-Income-Tax State
Nine states impose no individual income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you leave one of these for a state that does tax income, you owe your new state starting on your move date, and you have nothing to file with your former state because you weren’t filing there to begin with. Moving the other direction, you still file a final part-year return in your old state covering the months you lived there. After that, the only thing that pulls you back into filing is income sourced to the old state, like rent from a property you kept.
