Tax Overview
This state uses a progressive income tax system with multiple brackets, similar to the federal system. Only the income within each bracket is taxed at that rate, so your effective state rate is lower than the top bracket. Tax planning strategies include maximizing pre-tax retirement contributions to reduce state-taxable income.
Tax Planning Tip
In a progressive-bracket state, pre-tax 401(k) and HSA contributions reduce your state tax bill along with federal tax. If you are near a bracket boundary, an additional contribution can drop you into a lower state bracket.
Delaware's progressive income tax applies marginal rates to each income bracket. The top rate of 6.6% applies to income over $25,000, meaning most working residents reach the top bracket. Delaware uses its own standard deduction and personal exemption amounts. Delaware has no state sales tax, which partially offsets the income tax burden. Social Security benefits are excluded from Delaware taxable income. Taxpayers aged 60 and older can also exclude up to $12,500 in pension and eligible retirement income.
