How are state taxes handled in the year I move to another state?

Each state taxes its part of the year. You file a part-year resident return in the state you leave, for the months you lived there, and another in the state you move to, for the rest of the year. A state with no income tax files nothing. Each state taxes a part-year resident its own way: some take a share of the tax a full-year resident would owe, some prorate the deductions, some give a credit for the months away and some tax only the income received while you lived there.

Does this page compute the move-year tax for every state?

For all 42 jurisdictions with an income tax, yes: the tax engine copy in your browser carries their part-year rules and files both part-year returns, each kind of income split by the days you lived in each state, the same returns the retirement planner files for the move year, checked against the state engine to the cent. A state with no income tax taxes its part at $0. The planner files the part-year return for a year a state's instructions do not say how to apportion, and for a move to or from Washington.

Does my federal tax change when I move to another state?

No. The federal income tax on the same income is the same in every state, so the difference a move makes is the difference in state (and local) income tax. The calculator shows the federal tax once.

If I move to a state with no income tax, does my old state still tax me?

For the months before the move, yes: the state you leave taxes you as a part-year resident on the income of those months, and most states also tax income that comes from the state itself after you leave, such as wages earned there or rent from property there. Retirement income received after you move is not taxable by the state you left: federal law (4 U.S.C. 114) bars a state from taxing a nonresident's retirement income.

What these figures include, and what they leave out

Included: each state’s 2026 income tax on your household as a full-year resident: its exemptions for Social Security, pensions and IRA money, its age-based subtractions, its deductions, exemptions, brackets and credits, computed by QuantCalc’s state tax engine from each state’s own rules (how the engine works, with every source). Both states get the federal figures of your own federal return.
The move year: each state’s part-year resident return by its own part-year rules, computed as the planner files the move year: each kind of the year’s income split by the days you lived in each state, a married couple at the filer’s age with no split between the spouses. A move to or from Washington is left to the planner, as is a year a state’s instructions do not say how to apportion. Income you can place in time yourself (a large IRA withdrawal or a sale before or after the move) can be taxed by a different state than an even split assumes.
The Indiana and Maryland figures include the county income tax at the engine’s default county rate (Indiana 1.75%, Maryland 3.12%); other local income taxes (city and school-district taxes, and county taxes in other states) are not included.
Washington has no income tax; its figure is its tax on long-term capital gains.
Not included: property, sales and estate taxes; itemized deductions (each return takes the standard deduction); Roth conversions; dependents, blindness and disability; the credit one state gives for tax paid to the other; and income that comes from the old state after you leave, such as wages earned there or rent from property there (what the state you leave still taxes).
