Bonus Tax Calculator for Delaware

When you receive a bonus in Delaware, your employer typically withholds at the federal supplemental rate of 22%, plus Delaware's supplemental rate (often the top marginal rate of 6.6%), and FICA at 7.65%. Local income taxes in some parts of Delaware take an additional cut. The combined withholding can make bonuses feel heavily taxed, though your actual liability may differ from withholding at year-end. This calculator shows both the withholding and the true tax on your bonus in Delaware.

Delaware uses a graduated income tax with brackets ranging from 2.2-6.6%. Lower income is taxed at lower rates, with the 6.6% 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 Delaware 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.

The table below shows what you actually keep at five salary levels in Delaware, accounting for federal tax, FICA, and Delaware's graduated (2.2-6.6%) state tax plus estimated local taxes.
