RSU Tax Calculator for Mississippi

RSU vesting in Mississippi triggers a flat 4% state income tax, treated as ordinary income just like your salary. Your employer typically sells shares at vesting to cover the combined federal, state, and FICA withholding, which can consume 35-50% of the vested shares depending on your income level. This calculator shows you exactly how many shares (or dollars) you keep after all Mississippi tax layers are applied.

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.

The table below shows what you actually keep at five salary levels in Mississippi, accounting for federal tax, FICA, and Mississippi's flat 4% state tax.
