Frequently Asked Questions — District of Columbia State Taxes
Does District of Columbia have a state income tax?
Yes. District of Columbia levies a state individual income tax in 2024. The rates and brackets shown above apply to residents filing as single or married filing jointly. Progressive rates up to 10.75%. Estate tax exemption ~$4.5M.
How do District of Columbia tax brackets work?
Like federal taxes, District of Columbia uses a marginal (progressive) tax system. Only the income within each bracket is taxed at that rate — not all your income. For example, if District of Columbia has a 5% top rate, you pay 5% only on income above the top bracket threshold, not on your entire salary.
What is the difference between marginal and effective tax rate in District of Columbia?
Your marginal tax rate is the rate on your highest dollar of income. Your effective tax rate is your total state tax bill divided by your gross income — always lower than your marginal rate. For example, a worker at the top bracket in District of Columbia may have a marginal rate of 10.8% but an effective rate several points lower due to income in lower brackets.
