Montana has open primaries. Any registered voter can participate in primary elections, regardless of political party. 17-year-olds cannot vote in the primary election even if they will be 18 by the corresponding general election.

ID is required to vote in Montana. Valid forms of ID include:
- A current photo ID showing the elector’s name
- A current utility bill, bank statement, paycheck, voter registration confirmation, government check, or other government document showing the elector’s current name and current address

If you go to your polling place without an approved form of ID, you can still vote by requesting and filling out a “Polling Place Elector ID” form. Or, you can vote a provisional ballot. Your provisional ballot will be counted if you provide valid ID to the county election office by 5:00 p.m. the day after the election, or mail it to the county election office postmarked by the day after the election.
