How to vote in Connecticut
Registration deadlines, ID, mail and early voting in Connecticut, in plain English, with the official links. The Connecticut Secretary of the State, Elections Division is the final word on every rule.
| Register online | Yes: Submitted by 11:59 p.m. 18 days before Election Day. |
|---|---|
| Register by mail | Postmarked (or received by your Registrars of Voters) 18 days before Election Day. |
| Register in person | By 8 p.m. at your Registrars of Voters office 18 days before Election Day; after that, use same-day registration. |
| Same-day registration | Yes: register and vote at your town's Same-Day Registration location during early voting hours and on Election Day. |
| Voter ID | You are asked for ID (photo ID or a bill or document with your name and address); if you have none you can sign a statement (Form ED-681) and vote, while some first-time voters must show ID. |
| Voting by mail | No-excuse absentee ballot (new for 2026); ballots must reach your Town Clerk by 8 p.m. on Election Day. |
| Early voting | 14 days of in-person early voting at your town's early voting location, ending the Sunday before Election Day. |
| Statewide elections in 2027 | No statewide election in 2027; municipal elections are held in odd years, mostly on the Tuesday after the first Monday in November (November 2, 2027), with a few towns, cities and boroughs voting on May 3, 2027. |
New for 2026: registration closes 18 days before Election Day (it was 7), and you no longer need an excuse to vote absentee.
