Three ways to register

Each cutoff below is District of Columbia's own rule, counted back from Election Day - not a date. The date it lands on depends on the election, so confirm it for yours on District of Columbia's registration page.

Official resources

Sourced from the offices that run the election. Deadlines for a specific election, sample ballots, and polling places all live with them.

Registration channels, cutoff rules, and official links on this page are read from vote.gov's District of Columbia page, last updated March 11, 2026. Cutoffs are stated as District of Columbia's rule relative to Election Day; for the calendar date in a particular election, and for anything a rule change may have moved since that stamp, the District of Columbia election office is authoritative.
