District of Columbia 529 State Tax Benefit (2026)

Deduction of up to $4,000 ($8,000 on a joint return), per taxpayer. Only contributions to DC College Savings Plan count; money put into another state’s plan earns no District of Columbia deduction or credit.

Contributions above the annual limit carry forward for up to 5 years, subject to the annual limit.

Only account owners can deduct, for accounts they own; the $8,000 joint limit requires each spouse to own an account. Rollovers in don't count as contributions. The deduction is recaptured whenever a nonqualified withdrawal is made, and on a rollover to another state's plan within 2 years of opening the account (D.C. Code §47-4509(c)); the earnings in a nonqualified withdrawal are also DC-taxable. Part-year residents count only contributions made while living in DC.
