Open Marriage Tax Calculator →Delaware's graduated (2.2-6.6%) state income tax interacts with federal brackets to create marriage bonuses or penalties that differ from the federal-only effect. Delaware's graduated brackets may create a separate state-level marriage penalty if both spouses earn similar incomes, layering on top of any federal penalty. Local income taxes in Delaware add yet another variable to the marriage tax equation. This calculator shows the combined federal and Delaware state marriage tax impact.
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.
