Open Overtime Tax Calculator →Overtime hours in Oregon face a combined state and federal marginal rate that can surprise workers. With a top state rate of 9.9% stacking on top of the federal 22% supplemental rate and 7.65% FICA, overtime income can be taxed at over 39.5% at the margin. Local income taxes push this even higher in some Oregon jurisdictions. 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.
Oregon uses a graduated income tax with brackets ranging from 4.75-9.9%. Lower income is taxed at lower rates, with the 9.9% 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 Oregon 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.
