About District of Columbia state taxes (Tax year 2026)
The District of Columbia uses a progressive income tax with 7 brackets ranging from 4% on the first dollars of taxable income up to 10.75% on income over $1,000,000. DC residents file Form D-40 even though DC is not a state; the highest bracket rivals California and New York among the top marginal rates in the country.
The District of Columbia general sales tax rate is 6.0% with higher rates on prepared food (10%), alcohol (10.25%), parking (18%), and hotels (14.95%). Groceries and prescription drugs are exempt.
DC's top marginal rate of 10.75% is far above the national average of ~4.6% and edges past neighboring Maryland (5.75%) and Virginia (5.75%). Because DC residents cannot deduct DC tax against any state-level tax owed elsewhere, multi-jurisdiction filers should track residency days carefully.
Filing in District of Columbia: returns for tax year 2026 are administered by the District of Columbia Office of Tax and Revenue (OTR) and are generally filed in 2027 by the federal April deadline unless District of Columbia declares a state-specific extension. Tax type on this return: Progressive. Top marginal rate: 10.75%. State sales-tax rate: 6.0%. For the most current contact info, see the Federation of Tax Administrators directory.
District of Columbia — Does the District of Columbia have a state income tax? DC is not a state, but its local income tax functions like one. Residents and people who work in DC pay tax on income earned there, with rates from 4% to 10.75% across seven brackets.
District of Columbia — What is the DC standard deduction? DC conforms its standard deduction amounts to the federal standard deduction. The DC Office of Tax and Revenue publishes the exact figures each year in its D-40 instructions.
District of Columbia — Do I pay DC income tax if I work in DC but live in Maryland or Virginia? No. Maryland and Virginia have reciprocity agreements with DC. If you live in either state and work in DC, you pay income tax only to your state of residence and file a non-resident DC return only if required for withholding refunds.

Methodology
State-tax per-state pages apply the published 2026 bracket schedule, standard deduction, and filing-status rules for the listed jurisdiction. Federal AGI inputs are mapped to state taxable income before bracket math runs. Local taxes (NYC, Philadelphia, certain Ohio cities) are flagged but not embedded in the base estimate.
Assumptions
- The user enters federal AGI, filing status, and state-specific adjustments as provided.
- Brackets, standard deductions, and credits reflect the 2026 statutory values published by the state Department of Revenue and the Tax Foundation.
- Local income taxes and reciprocity-agreement situations are noted but not auto-applied.
Limitations
- These pages do not predict mid-year legislative changes, rate adjustments, or new local tax assessments.
- Multi-state filers, convenience-of-employer rules, and special-circumstance credits require additional tax-professional analysis.
