Choose the voting method that works for you. Deadlines depend on that method. Check the time and delivery requirements, not just the date. Military, overseas, and emergency voting may have separate rules.
01
Register
Register online or submit a paper application. October 26 is the cutoff to register and receive a ballot by mail. Afterward, visit a voter service and polling center to register and vote through Election Day.
Registration-drive deadline
October 13 is the registration-drive deadline in the official 2026 calendar. Other registration methods remain available.
Active registered voters receive a ballot by mail automatically. Sign the envelope and return it to an official location or mail it early enough to arrive by 7 p.m. Election Day. Military and overseas voters have separate return rules.
Domestic mail-ballot distribution begins
The revised 2026 calendar permits initial mailing October 2; counties must send initial packets to active eligible voters by October 9. Delivery dates vary.
November 3, 2026. Poll hours: 7:00 a.m.–7:00 p.m. Mountain time. Check your official ballot, voting location, and identification requirements before you go.
Date labels compare calendar dates in Mountain time; “Today” does not mean the cutoff time has not passed. Confirm local times with your election office.
