Wisconsin charges 3.5-7.65% state income tax. Use the stock option tax calculator pre-loaded with Wisconsin rates.
Open Stock Option Tax Calculator →Stock option exercises in Wisconsin are subject to up to 7.65% state income tax on top of federal tax. For NSOs, the spread at exercise is ordinary income subject to both federal and Wisconsin state tax plus FICA. For ISOs, while there is no regular tax at exercise, the spread counts for AMT purposes and for Wisconsin state tax calculations. This calculator helps you plan the optimal time and amount to exercise given Wisconsin's tax rates.
Wisconsin uses a graduated income tax with brackets ranging from 3.5-7.65%. Lower income is taxed at lower rates, with the 7.65% 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. Wisconsin does not have local income taxes, so the state graduated rate is the total state-level income tax burden.
