District of Columbia state income tax: what you actually pay
District of Columbia charges a graduated schedule topping out at 10.75%. On $100,000 of income a single filer owes about $6,900 in state income tax, an effective rate of 6.90%, with the next dollar taxed at 8.50%. The same income is untaxed by the nine states that levy nothing, and costs $8,431 in Oregon.
District of Columbia applies a graduated schedule topping out at 10.75% to your income after its own standard deduction of $16,100 for a single filer. That deduction matters more than people expect: it is not the federal one, and a state that grants none taxes the first dollar you earn.
The distinction that matters for planning is between your EFFECTIVE rate and your MARGINAL rate. At $100,000 the effective rate here is 6.90%, which is what you actually pay across all your income. The marginal rate is 8.50%, which is what the NEXT dollar costs. Use the effective rate to budget and the marginal rate to price a decision such as a Roth conversion, a bonus or a property sale. Mixing them up is the single most common error in state tax arithmetic, and it usually flatters the decision.
Whether moving is worth it starts with this number and rarely ends with it. Leaving District of Columbia for a state with no income tax saves the $6,900 above at $100,000, and roughly $19,650 at $250,000. Against that sit property tax, sales tax and insurance, which the no-income-tax states generally set higher precisely because they collect nothing on income. A state with no income tax is not a state with no taxes.
What these figures do not include, and any of them can change the answer for a specific household. Local income taxes, which some cities levy on top of the state, New York City and Philadelphia being the largest. Credits and exemptions beyond the standard deduction, which most states offer and which reduce the bill. Retirement-income exclusions, which are common and generous: several states exempt pension or retirement-account income entirely for older residents, so a retiree's real bill can be far below the schedule here. And the treatment of capital gains, which most states tax as ordinary income but a few do not.
A note on how these numbers are produced. They come from the published schedule for each state, stored with its source and re-derived from the publisher's own workbook rather than typed in by hand. That is deliberate: a transcribed tax table is a typo generator, and a typo in this kind of figure arrives wearing a citation.

Frequently asked
How much state income tax will I pay in District of Columbia on $100k?
About $6,900 as a single filer, an effective rate of 6.90%. That applies District of Columbia's own standard deduction and its published brackets, and excludes local taxes and any credits you may qualify for.
What is District of Columbia's top income tax rate?
10.75%. That is the rate on the highest band, not the rate you pay on all your income: at $100,000 the effective rate here is 6.90%.
Would moving to a state with no income tax actually save me money?
On the income tax line, yes: $6,900 a year at $100,000 and more as income rises. Whether you come out ahead overall depends on property tax, sales tax and insurance, which are usually higher in states that collect nothing on income, and on the cost of the move itself.
Do these figures include city taxes?
No. Local income taxes are levied separately by some cities and counties, and they are not in these numbers. New York City and Philadelphia are the two that most often change the answer materially.
Does my state tax my retirement withdrawals?
These figures assume it does, which is the conservative reading. In practice many states exempt some or all retirement income for older residents, and a few exempt pensions entirely, so a retiree in a taxing state often pays considerably less than the schedule here implies.
