District of Columbia Capital Gains Tax Calculator
District of Columbia taxes capital gains as ordinary income at the state level, which means a gain on selling shares, property or other investments is added to your other income and taxed using the District of Columbia income tax brackets, with no separate preferential long-term rate like the federal system provides. This calculator estimates the District of Columbia state tax on a capital gain by stacking the gain on top of your other taxable income and applying the sourced DC Office of Tax and Revenue brackets for tax year 2024, then taking the difference. Enter your gain, your other annual taxable income and your filing status to see the state tax attributable to the gain and the effective rate on it. The result is the District of Columbia state portion only; federal capital gains tax, which has separate short-term and long-term rates set by the IRS, is calculated separately. Because the gain stacks on your other income, the same gain is taxed at a higher rate the more you already earn. Some states provide specific exclusions or preferential treatment for certain gains; this tool uses the standard ordinary-income method and links the DC Office of Tax and Revenue so you can confirm any special rule that applies to you.

DC has reciprocity agreements with Maryland and Virginia. Residents of those states who work in DC pay income tax only to their home state, not to DC.

DC residents pay full federal income taxes but have no voting representation in the US Senate or House (they have a non-voting delegate). This is a long-standing political issue. For tax purposes, DC residents file federal Form 1040 and DC Form D-40, the same as residents of any state.
