This calculator shows both the withholding and the true tax on your bonus in Mississippi.
Mississippi levies a flat 4% state income tax on all taxable income regardless of how much you earn. This makes tax planning straightforward: for every additional dollar you earn, 4 cents goes to Mississippi. Mississippi does not impose local income taxes, so the 4% flat rate is the only state-level income tax you owe.
