Absentee ballots sent by mail or left in your town's official drop box must be received by the Town Clerk by 8:00 PM on Election Day; postmarks do not count. If you return your ballot to the Town Clerk in person yourself, you must do so by Monday, November 2. A family member or designated caregiver returning it in person has until 8:00 PM on Election Day.
Regular in-person registration closes Oct 16 (mandatory registrars' session 9 AM-8 PM). After that, Same Day Registration is available in person at early voting locations Oct 19-Nov 1 and at your town's designated Same Day Registration location on Election Day. Same Day Registration is offered at early voting locations (Oct 19-Nov 1) and on Election Day at each town's designated SDR location (not at regular polling places).
Connecticut's registration deadline is the seventh day before the election — Tuesday, October 26, 2027. Connecticut also offers same-day registration, so voters who miss it can still register and vote in person on election day at their town's designated location.
Connecticut sets one statewide municipal election day in statute. Conn. Gen. Stat. § 9-164(a) puts a municipal election in every municipality on the Tuesday after the first Monday of November in odd-numbered years, which in 2027 is Tuesday, November 2 (November 1, 2027 is a Monday). The one exception the statute allows is that a municipality's legislative body may vote by a three-fourths majority to hold the election on the first Monday of May of an odd-numbered year instead, so check with your town or city clerk if you are unsure.
