District of Columbia Tax Calculator

The District of Columbia taxes income through a tiered bracket system, much like a state, even though DC functions as both a city and a state for tax purposes. Higher earners move through several brackets before reaching the top rate, which applies only to a very high slice of income. This calculator applies DC's current brackets to your entered income to compute your exact liability.

How District of Columbia income tax works

  • DC layers multiple brackets, so each portion of income is taxed at its own rate.
  • As both a city and a jurisdiction with state-level tax authority, DC administers its own income tax return separate from Maryland or Virginia.
  • The calculator reports your marginal and effective DC rate based on your entered taxable income.

Frequently asked questions

How is DC income tax calculated?

The District applies a tiered bracket schedule similar to a state income tax, taxing each portion of your income at its own rate. The calculator applies the current brackets to your entered figures.

Does DC tax Social Security benefits?

No. The District excludes Social Security benefits from taxable income.

Is DC's income tax different from a state's?

Functionally, no — DC administers its own income tax return and bracket schedule just as a state would, even though it isn't a state. Residents file a DC return separately from any federal filing.

How much state tax will I pay in DC?

It depends on where your income falls across DC's brackets. Enter your income above for an exact, bracket-by-bracket total.
