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? The 2026 DC basic standard deduction is $15,000 for single filers, $30,000 for joint filers, and $22,500 for heads of household. This estimate excludes additional deductions and credits.
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.

Methodology
These pages estimate annual state income tax for the selected 2026 jurisdiction and filing status. The route's coverage panel identifies the supported income basis, deductions, credits and exclusions.
Assumptions
- Enter the income basis and eligible pre-tax deductions requested by the calculator; gross wages, federal AGI and state AGI are not interchangeable.
- Some methods require confirmed state facts or explicit projection assumptions. An unavailable component is not zero tax.
Limitations
- The estimate excludes unmodeled income, adjustments, local taxes and special filing situations. Utah's indexed-credit assumptions remain provisional while final 2026 instructions are pending.
- Annual liability differs from withholding and paycheck take-home. Confirm the current official forms and source versions for a complete return.
