How Mississippi state income tax works

Mississippi taxes wages at a flat 4 percent rate for 2026, but only on income above the $10,000 exemption threshold. The first $10,000 of taxable income is exempt from state income tax, which effectively lowers the rate paid on total gross wages for most workers. Mississippi reduced its rate from 5 percent in recent years as part of a legislatively enacted phase-down, and the 4 percent rate continues the state's trend toward a lower flat structure.

On a $65,000 salary, Mississippi state income tax is about $2,600 per year. That figure applies the 4 percent rate to the full $65,000 for simplicity, though factoring in the $10,000 exemption and standard deduction would bring the taxable base and the resulting tax somewhat lower. Mississippi also provides a standard deduction and personal exemption that reduce taxable income before the rate is applied, so actual withholding typically runs below a raw percentage-of-gross calculation.

Mississippi does not impose local income taxes at the city or county level, so all Mississippi residents face the same statewide 4 percent rate with no municipal add-on. The calculator covers federal income tax brackets, FICA (Social Security and Medicare), and the Mississippi flat rate, which you can adjust to reflect your actual withholding.
