Stock Option Tax Calculator for Mississippi

Stock option exercises in Mississippi are subject to a flat 4% state income tax on top of federal tax. For NSOs, the spread at exercise is ordinary income subject to both federal and Mississippi state tax plus FICA. For ISOs, while there is no regular tax at exercise, the spread counts for AMT purposes and for Mississippi state tax calculations. This calculator helps you plan the optimal time and amount to exercise given Mississippi's tax rates.

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.
