Delaware Tax Calculator
Delaware taxes income through a tiered bracket system, and because the state has no sales tax at all, income tax carries an outsized share of state revenue. Most working residents reach Delaware's top bracket at a relatively modest income level. Older residents can also exclude a portion of pension and retirement income from state tax. This calculator applies Delaware's brackets to your entered income.
