Open Overtime Tax Calculator →Overtime hours in Wisconsin face a combined state and federal marginal rate that can surprise workers. With a top state rate of 7.65% stacking on top of the federal 22% supplemental rate and 7.65% FICA, overtime income can be taxed at over 37.3% at the margin. Understanding this stacking effect is essential before committing to extra shifts. The overtime calculator breaks down exactly how much of each overtime dollar you actually keep.
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.
