States where you keep 100% of your salary from state income tax. Compare take-home pay, cost of living, and real purchasing power.
These 9 states charge zero personal income tax, allowing residents to keep 100% of their salary from state-level income taxes. However, no-tax doesn’t always mean low-tax — states often compensate with higher property taxes, sales taxes, or fees. The real question is purchasing power after all taxes and living costs.
Alaska offers the best cost-adjusted value among no-tax states with a cost of living index of 127. In contrast, Wyoming’s cost index of 94 means your tax savings are partially eaten by higher living expenses. The spread between the best and worst no-tax state (by purchasing power on $100K) is $-21,872/year.
