Delaware‘s tax system ranks 18th overall on the 2025 State Tax Competitiveness Index. Delaware, despite maintaining several distinctly uncompetitive provisions, ranks above average on the Index due to its lack of a sales tax. Delaware has a graduated individual income tax with a top rate of 6.6 percent kicking in at $60,000. In addition, the city of Wilmington collects its own individual income tax of 1.25 percent, the only jurisdiction to do so. Taxpayers in the state also face a marriage penalty, where a household’s overall tax bill increases due to a couple marrying and filing taxes jointly.
Delaware has an 8.7 percent corporate income tax rate and is one of only two states with both a corporate income tax and a gross receipts tax (GRT), which applies to gross sales, without deductions for a firm’s business expenses, like costs of goods sold and compensation, and without regard for ability to pay. This leads to tax pyramiding, favors high-profit-margin companies, and can cause low-profit-margin firms to cease operations. Most states have abandoned GRTs due to the economic harm and inefficiencies they cause. Delaware also imposes a capital stock tax. The state does benefit, however, from its lack of a state sales tax, as well as its reasonable 0.48 percent effective property tax rate on owner-occupied housing value.
Delaware does not levy an estate tax or inheritance tax, a notable competitive advantage compared to most of its regional competitors. However, the state does impose an uncompetitive convenience rule and requires nonresident individual income tax filing and withholding for nonresidents who work for even a single day in the state. Delaware is perhaps most notable for policies that make it more attractive as a place in which to incorporate than a state in which to actually conduct significant business operations. Its Court of Chancery, which wins many plaudits, is well outside the scope of the Index, while its uniquely favorable treatment of royalty income does not benefit the state on the Index.
