US State Income Tax in 2026
How much a state takes out of your paycheck depends entirely on where you live. In 2026, states fall into three groups: no income tax, a single flat rate, or graduated brackets.
States with no income tax (9)
These states do not tax wages, so your paycheck is reduced only by federal taxes.
Flat-rate states (15)
These states apply a single rate to taxable income, regardless of how much you earn.
