Moving to a No-Income-Tax State: The Math Beyond the Headline

The pitch writes itself: earn $120,000 in a state with a 6% income tax, move somewhere with none, keep an extra several thousand dollars a year. Nine states — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — levy no broad wage income tax. The savings on that line are genuine. The question is what the rest of the ledger does.

States fund themselves somehow

A state without an income tax still plows roads and runs schools. The money comes from elsewhere:

• Property tax — Texas and New Hampshire rank among the highest in the country; on a $400,000 home, the difference against a low-property-tax state can be several thousand dollars a year by itself.
• Sales tax — Tennessee and Washington combine state and local rates near the top nationally, taxing spending instead of earning.
• Targeted taxes — Washington taxes large capital gains; New Hampshire long taxed interest and dividends; severance taxes on oil and minerals quietly fund Alaska and Wyoming.

The comparison that actually decides it

Line up, for your specific situation: income tax on your salary in each state; property tax on the home you would actually buy (local rates vary wildly within states); sales tax against your spending; insurance premiums (coastal Florida and Texas homeowners insurance can erase years of income-tax savings); and the price of the house itself. A high earner renting modestly captures nearly the full income-tax saving. A family buying a large home in a high-property-tax county may keep little of it.

Two cautions

Remote workers: some states apply "convenience of the employer" rules that keep taxing wages after you leave, and a move must be a genuine domicile change — driver's license, voter registration, time actually spent — to survive an audit by the state you left. High earners with equity compensation should check how each state treats vesting that straddles the move.

Start with the income-tax line itself: the state income tax calculator compares your salary's state bill across published states, and the state paycheck calculators show the full per-check picture in each one.
