District of Columbia Standard Deduction
The District of Columbia standard deduction is a flat amount you can subtract from your gross income before District of Columbia income tax is calculated, instead of itemising individual deductions. This page shows the District of Columbia standard deduction for tax year 2024 by filing status, sourced directly from the DC Office of Tax and Revenue, and calculates your District of Columbia taxable income after the deduction. Enter your gross income and choose your filing status to see the deduction that applies and the taxable income that remains. Most filers take the standard deduction because it is simpler and, for many, larger than their itemisable deductions. You should itemise only if your allowable District of Columbia itemised deductions add up to more than the standard amount. The standard deduction is separate from the federal standard deduction the IRS applies to your federal return, and from any personal exemptions or credits District of Columbia provides. Use this alongside the District of Columbia income tax calculator to see how the deduction flows through to your final state tax. All figures here are the official published amounts; nothing is estimated.
The District of Columbia standard deduction for 2024 is $14,600.00 (single) and $29,200.00 (married filing jointly). On $60,000.00 of gross income, a single filer has $45,400.00 of District of Columbia taxable income.

Should I take the District of Columbia standard deduction or itemise?
Take whichever is larger. If your total itemised deductions allowed by District of Columbia exceed the standard deduction of $14,600.00 (single) or $29,200.00 (married jointly), itemising lowers your taxable income more. Otherwise the standard deduction is simpler and larger. Check the rules with the DC Office of Tax and Revenue.

If I work in DC but live in Maryland or Virginia, which state's income tax do I pay?
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 working in MD or VA likewise pay DC tax, not MD or VA tax. Commuters should confirm their employer withholds for the correct jurisdiction.
Does the lack of voting representation in Congress affect DC's tax structure?
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.
