Mississippi Tax Calculator

Mississippi taxes income at one flat rate, but only above an initial slice of income that's exempt entirely — effectively creating a zero-rate starting band before the flat rate kicks in. The rate itself was cut again for 2026. Mississippi does not tax Social Security or most other retirement income. This calculator applies Mississippi's current structure to your entered income.
