The tax implications of moving to a new state usually come down to four things: which state gets to tax which slice of your income during the year you move, how to keep the same dollars from being taxed twice, whether your new state treats retirement income, estates, and remote wages differently from your old one, and what paperwork you need to update right away so withholding and registrations line up with reality. Nine states charge no income tax at all, others push top rates past 13 percent, and the transition year is where most people trip.
Residency and Domicile Decide Who Taxes You
States use two concepts to decide whether you’re their resident. Your domicile is the state you treat as your permanent home, the place you intend to return to. You can only have one at a time, and it doesn’t shift automatically. It changes when you physically move to a new state with genuine intent to stay.
Statutory residency is a separate test based on days. Most income-tax states use a 183-day threshold: if you’re physically present for at least 183 days during the tax year, the state can treat you as a resident regardless of domicile. That matters most for people who split time between two states rather than clean-break movers.
Proving You Actually Left
High-tax states that lose residents to lower-tax states have a financial incentive to argue you never truly left. If your former state audits you, it looks at where your driver’s license was issued, where you’re registered to vote, where your spouse and dependents live, and the location of your primary residence. Auditors also weigh bank accounts, doctors and attorneys, and social and religious connections.
The strongest moves sever ties decisively. Change your driver’s license and voter registration promptly. Sell or lease out property in your former state. Transfer professional memberships and update legal documents like your will. Keep utility bills, leases, and travel records that show your presence in the new state. A clean break is more convincing than a gradual drift.
Filing Two Part-Year Returns
For the calendar year you move, you’ll typically file a part-year resident return in both states. Your former state taxes income you earned while you still lived there, plus any income sourced to that state for the rest of the year. Your new state taxes income earned from the date you established residency onward.
Wages get split by when you worked in each state. If you moved on July 1 with a $100,000 salary, roughly half goes on each return. Interest and dividends follow residency: whichever state you lived in when the income was received gets to tax it.
Income tied to a specific location doesn’t follow you. Rental income from property in your old state, profits from a business operating there, or gains from selling real estate there remain taxable by that state after you’ve moved. You’ll file a nonresident return covering that income going forward.
The Credit That Prevents Double Taxation
When two states both have a legitimate claim on the same income, most states prevent you from paying twice through a credit. Your resident state allows a credit for taxes you paid to the other state on income both states taxed. The credit is typically limited to the lesser of what you actually paid the other state or what your home state would have charged on that same income. You effectively pay the higher of the two rates on the overlapping income, not both stacked.
This credit isn’t automatic. You claim it on your resident state return and usually attach a copy of the return filed in the other state. Missing this step is one of the most expensive mistakes in a transition year.
Remote Work After the Move
If you move but keep working for an employer based in your old state, the situation gets more complicated. Most states tax income based on where the work is physically performed, so remote work from your new home generally shifts your wages to that state.
The exception is the convenience of the employer rule. Under this doctrine, if you’re working remotely for your own convenience rather than because your employer requires it, the employer’s state still claims the right to tax your wages. Connecticut, Delaware, Nebraska, New Jersey, New York, and Pennsylvania maintain versions of this rule. New York’s is the most aggressive, presuming all remote work is for the employee’s convenience unless the employer proves otherwise. Live in a neighboring state and work remotely for a New York employer, and you could owe New York tax on your full salary even though you never commute there.
Your new home state will also want to tax those wages since you’re a resident. The credit for taxes paid to another state helps, but you may end up paying the higher of the two rates. Tell your employer’s HR or payroll department about your move immediately so withholding shifts to the correct state. Many states require employers to withhold from the first day an employee works within their borders, and skipped updates lead to large bills.
Selling Your Home Around the Move
Federal law lets you exclude up to $250,000 of capital gain from the sale of your principal residence, or $500,000 if married filing jointly, provided you owned and lived in the home for at least two of the five years before the sale.1Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence You can only use this exclusion once every two years.
Most states follow the federal exclusion. The bigger question for movers is which state taxes any gain above it. Real property is generally taxed by the state where the property sits, not where you live at the time of sale. If you move first and sell later, your former state will still expect a nonresident return reporting any taxable gain. Your new resident state may also tax it, but the credit for taxes paid to another state should prevent true double taxation.
Retirement Income and Social Security
For anyone drawing retirement income, the destination state can change your annual tax bill significantly.
The nine no-income-tax states — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — exempt all retirement income by default. Beyond those, Illinois, Iowa (for those 55 and older), Mississippi, and Pennsylvania exempt pension income, 401(k) distributions, and IRA withdrawals from state tax even while taxing other income. Many other states offer partial exemptions with widely varying thresholds.
Social Security is a separate question. At the federal level, up to 85 percent of your benefits may be taxable depending on total income. Most states exempt Social Security entirely, but eight still tax it to some degree as of 2026: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, and Vermont. Each applies its own income thresholds and exemption rules. Moving from one of these states to one that exempts Social Security can save retirees thousands a year.
Estate and Inheritance Taxes
If your move is permanent, particularly in retirement, estate and inheritance taxes deserve a look. The federal estate tax exemption for 2026 is $15 million per person, so most estates owe nothing federally.2Internal Revenue Service. What’s New — Estate and Gift Tax State thresholds are often far lower.
Twelve states and the District of Columbia impose their own estate tax, with exemptions ranging from $1 million in Oregon to over $7 million in states like New York. Connecticut matches the federal exemption. Washington’s top estate tax rate is 35 percent, the highest in the country; other states cap out in the 12 to 16 percent range.
Five states levy an inheritance tax, paid by the person receiving the assets rather than the estate: Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Maryland is the only state that imposes both. Inheritance tax rates typically depend on the relationship between the deceased and the beneficiary, with spouses and direct descendants often exempt or taxed at low rates and more distant beneficiaries facing steeper rates. Moving from a state with an estate tax to one without can be one of the more consequential long-term planning decisions available to you.
Sales Tax, Property Tax, and Vehicle Registration
Income tax gets the attention, but day-to-day taxes add up and can shift your cost of living more than you expect.
Sales tax rates vary by state and locality. Alaska, Delaware, Montana, New Hampshire, and Oregon have no state sales tax; combined state and local rates exceed 10 percent in parts of other states. Property taxes are assessed locally and vary enormously, even between neighboring counties in the same state. A home with the same market value can carry two or three times the annual property tax depending on jurisdiction. Look at the effective rate in your specific county before buying, not just the state average.
You’ll also need to re-register vehicles in your new state, usually within 30 to 90 days of establishing residency. Expect a title transfer fee, new registration fees, and in many states a use or excise tax on the vehicle’s value. Title transfer fees alone range from a few dollars to over $200. If you recently bought a vehicle and paid sales tax in your former state, your new state may credit that against any use tax owed, though the rules vary.
The Moving Expense Deduction Is Gone for Most People
If you’re hoping to deduct your moving costs, the news is disappointing. Since 2018, the federal moving expense deduction has been available only to active-duty members of the Armed Forces who relocate due to a permanent change of station.3Internal Revenue Service. Instructions for Form 3903 Everyone else lost this deduction under the Tax Cuts and Jobs Act, and that remains the rule for 2026. A few states still allow a moving expense deduction on their own returns, but the federal deduction is off the table for civilian moves.
What to Do in the Transition Year
The transition year is where most mistakes happen. A few specific actions prevent the costliest ones.
Update your withholding. The federal W-4 controls federal withholding and should reflect any changes in your situation.4Internal Revenue Service. About Form W-4, Employee’s Withholding Certificate State withholding is separate — each state has its own withholding certificate, and your employer needs the new state’s version to withhold correctly. Moved from a no-income-tax state? If you don’t submit the new form, your employer may not withhold any state tax at all, leaving you with a surprise bill in April.
Prepare for part-year returns in both states, and a nonresident return in your former state for any lingering source income like rental property. Claim the credit for taxes paid to another state on your resident return.
Keep records that document the timing: your lease or closing date, the date you changed your driver’s license, moving company receipts, utility activation dates, and anything else showing when residency actually shifted. If either state questions your filing, this is your proof.
Watch for underpayment penalties. If withholding didn’t keep pace with what you owe — common when changing states mid-year — you may need to make estimated payments. At the federal level, you’re generally safe if total withholding and estimated payments equal at least 90 percent of your current-year tax or 100 percent of last year’s.5Internal Revenue Service. Topic No. 306, Penalty for Underpayment of Estimated Tax Most states use similar safe harbors with varying thresholds. A mid-year tax projection shortly after your move is the best way to catch a shortfall before it becomes a penalty.
