Open Stock Option Tax Calculator →Stock option exercises in Missouri are subject to up to 4.8% state income tax on top of federal tax. For NSOs, the spread at exercise is ordinary income subject to both federal and Missouri state tax plus FICA. For ISOs, while there is no regular tax at exercise, the spread counts for AMT purposes and for Missouri state tax calculations. Local taxes in parts of Missouri further increase the cost of exercising. This calculator helps you plan the optimal time and amount to exercise given Missouri's tax rates.
Missouri uses a graduated income tax with brackets ranging from 2-4.8%. Lower income is taxed at lower rates, with the 4.8% top rate applying only to income in the highest bracket. This progressive structure means your effective state tax rate is always lower than the top marginal rate. In addition, some Missouri localities impose their own income tax, which stacks on top of the state rate. This is especially notable in areas like certain cities and counties. Always check your local rate when calculating total tax liability.
