District of Columbia Retirement Tax Guide 2026

District of Columbia partially exempts Social Security benefits with age- and income-based thresholds — check the current year's form instructions for the exact phase-out.. Federally, up to 85% of benefits may be taxable depending on combined income (AGI + non-taxable interest + 50% of SS).

Traditional 401(k) and IRA distributions are taxed as ordinary income at both the federal and District of Columbia level (6.75% effective state income tax). Roth distributions, when qualified, are tax-free at both levels.

District of Columbia offers a partial pension or retirement income exclusion (often age- and income-based, frequently around $20,000–$45,000 of qualified retirement income per filer). Check the current 1040 instructions for the exact 2026 figure.

RMDs start at age 73 under SECURE 2.0 (rising to 75 in 2033). The first RMD year is the year you turn 73; you can defer that first distribution until April 1 of the following year, but doing so forces two RMDs in one tax year and often pushes you into a higher bracket.

Years between retirement and the first RMD are typically the best window for Roth conversions, especially for District of Columbia residents where the 6.75% state tax adds to the federal cost. A multi-year ladder filling the 12% or 22% federal bracket can shift large amounts to tax-free Roth status.

Most District of Columbia counties offer additional property tax exemptions, freezes, or deferrals for homeowners aged 65+. These can reduce assessed value, lock in the millage rate at the year you turn 65, or defer the entire bill until the home is sold. Eligibility is often income-tested.

On a $400,000 home, District of Columbia's 0.56% effective rate produces an annual bill of about $2,240. A 50% senior exemption would save roughly $1,120 per year for the rest of your life in the home — apply through your county assessor in the year you turn 65.
