More information on Montana voter eligibility

Regular registration closes 30 days before an election. Regular registration may be done through the mail, when you are applying for or renewing your driver license or ID card, or through a voter registration outreach event. 

Late registration is the 29-day period before an election. Eligible voters may register to vote or update their registration during the late registration period, until 12 pm the day before election day. In order to vote in the election, a voter must obtain their ballot in person. Find your local county election office.

Election Day registration: As a result of a March 2024 ruling by the Montana Supreme Court, voters may register in person until close of polls on Election Day. If you are in line by the closing time, then you have a right to vote.
