US federal income tax is the same everywhere — but state income tax varies dramatically. Nine states have no income tax at all. Others charge up to 13.3% (California). For someone earning $100,000, moving from California to Texas produces $8,000-$10,000 more in annual take-home pay with no change in gross salary. This guide explains how state income taxes affect your take-home pay and which moves produce the biggest financial difference — using the Salary Equivalent Calculator to show real numbers.
The Salary Equivalent Calculator at /tools/salary-equivalent/ handles all US states and shows after-tax take-home in both your origin and destination states.
Enter your gross salary and select two US states. The calculator computes after-tax take-home in each state using current 2026 state and federal tax rates, with FICA applied uniformly. The difference between the two take-home figures is your annual state income tax savings (or cost) from the move.
The state comparison calculator does not account for: property tax differences (use the Property Tax Calculator by State for that); cost of living differences in housing, food, and transportation; salary level differences if you would earn a different wage in the destination market; or local income taxes (NYC, Philadelphia, Cleveland, Columbus, and other cities levy local income taxes on top of state tax — these are not included in the state comparison).
New York City residents pay NYC income tax of 3.078%-3.876% in addition to NY state income tax. This significantly increases the savings from leaving NYC. A $150,000 NYC earner who moves to Florida saves: NY state income tax (~$9,800/year) + NYC income tax (~$5,200/year) = approximately $15,000/year in state and city tax savings. If that worker also no longer needs to pay NYC rent premiums, the financial benefit compounds.
State income tax is one component of the total tax and cost-of-living comparison between states.
Moving from California to Texas eliminates state income tax — but Texas has property tax rates nearly double California's effective rate for many homeowners (Texas ~1.60% vs California effective ~0.71% due to Prop 13). A $500,000 home in Texas: approximately $8,000/year property tax. The same $500,000 home's California property tax depends heavily on when it was purchased — a 1990 purchase might have an assessed value of $150,000 (2% annual Prop 13 growth × 35 years), meaning only $1,500/year in California property tax. Moving from California to Texas can actually increase total tax burden for homeowners buying expensive homes in Texas.
States without income tax raise revenue through higher property taxes (Texas, New Hampshire), higher sales taxes (Nevada, Washington), or resource extraction taxes (Alaska — oil revenue funds state government). The zero income tax is real and meaningful, but the broader tax picture requires looking at all taxes paid, not just income tax.
State income tax matters most when: (1) income is high — a 10% state tax on $300,000 is $30,000/year; (2) you work remotely and can work for the same employer from any state; (3) you are approaching retirement and evaluating domicile for Social Security and pension income; (4) you have capital gains events (selling a business, stock options vesting) — state capital gains tax on a $1M event in California = $133,000; in Texas = $0.
Remote work has made state income tax selection more relevant than ever.
If you work entirely remotely for a company headquartered in a different state, generally only the state where you live (and work from) can tax your wages. If you live in Texas but work for a California company via remote work, you typically owe California income tax only on days physically worked in California — not on all your income. This is a significant change from the traditional commuter tax model.
A few states (New York, Connecticut, Delaware, Nebraska) use a "convenience of the employer" doctrine: if you work remotely for a New York company not because it's a necessity but because it's convenient for you, New York may still tax all your wages. This is a known complexity for remote workers who live outside these states but work for employers headquartered there. Consult a state and local tax specialist if this applies to your situation.
Some states tax all income of residents (domicile-based taxation) AND also tax non-residents on income earned within the state (source-based). Credits for taxes paid to other states usually prevent double taxation — but the mechanics require careful handling, especially in the first and last year of a move.
