Stock Option Tax Calculator for Alabama

Stock option exercises in Alabama are subject to up to 5% state income tax on top of federal tax. For NSOs, the spread at exercise is ordinary income subject to both federal and Alabama state tax plus FICA. For ISOs, while there is no regular tax at exercise, the spread counts for AMT purposes and for Alabama state tax calculations. Local taxes in parts of Alabama further increase the cost of exercising. This calculator helps you plan the optimal time and amount to exercise given Alabama's tax rates.

Alabama uses a graduated income tax with brackets ranging from 2-5%. Lower income is taxed at lower rates, with the 5% 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 Alabama 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.
