How to Register, Vote and Track Your Ballot in Montana

Posted on 11/28/22 by Jessica Ravitz, Natalie Missakian

En español | A state court struck down laws that ended Election Day voter registration and introduced new voter ID requirements, but the secretary of state has appealed to the Montana Supreme Court.

The 2022 midterms decided races for the U.S. House, Montana State Legislature, Montana Public Service Commission and various courts. The next statewide elections are in 2024, though there will be some local elections in 2023.

Voters In Montana Head To The Polls In Special Congressional Election

  • Absentee voting: Any registered voter can apply to automatically receive an absentee ballot in the mail, no excuses necessary.
  • Early in-person voting: This can be done by visiting your county elections office to fill out a paper ballot.
  • Voting at the polls: You'll need to show an acceptable ID that includes your name and current address.

A state court struck down 2021 laws that eliminated same-day voter registration on Election Day and introduced new voter ID requirements, among other changes. An appeal is pending with the Montana Supreme Court.

Montana gained one seat in the U.S. House, as determined by population growth in the 2020 census. The new congressional redistricting plan may affect certain boundaries of your district and which candidates appear on your ballot.

If you miss the deadline to register by mail, you can register late in person by visiting your county election administrator's office through Election Day. Note that a legal battle over Election Day voter registration is ongoing. For more information about voter registration and deadlines, visit the secretary of state’s website.

Check your voter registration status and update your information on the secretary of state’s My Voter Page.
