Compares state income tax only (federal tax and FICA are identical in both states). It does notinclude property tax, sales tax, or local/city income taxes. A state with no income tax (e.g. Texas, Florida) often makes up revenue through higher property or sales tax, so the income-tax winner isn’t always the cheaper place to live. 2026 estimate, standard deduction, not tax advice.

FAQ

- On a $100,000 salary, a single filer keeps about $4,192 more per year in Washington than in Idaho, looking at state income tax alone. The gap grows or shrinks with income. Use the calculator above for your salary.
- Does this include property and sales tax?
- No. This compares state income tax only. States with no income tax often have higher property or sales taxes, so the income-tax winner may not be the cheaper place to live overall. Federal income tax and FICA are the same in both states.
- What about moving mid-year?
- In the year you move, you typically file part-year resident returns in both states and split your income by your move date, so your first-year savings are smaller than a full-year comparison suggests.
