Voter ID Requirement
Photo ID required to vote in person (Montana SB 276, 2025): a current, valid, readable photo ID such as a driver's license/REAL ID, Montana state ID, military ID, tribal photo ID, U.S. passport, Montana concealed-carry permit, or Montana University System/NAIA photo ID. A voter whose photo ID does not show a current address must also bring a supplemental document (e.g., utility bill, bank statement, paycheck, or government document showing name and current address). Voters who cannot produce an acceptable photo ID use the provisional-ballot process through their county election official.

Regular registration closes 30 days before an election; late registration is available during the 30-day period before an election (in-person with county election officials)
Proof of Citizenship Law
No current requirement
NoteNo active statewide documentary proof-of-citizenship voter-registration requirement as of June 2026. Photo ID is required to vote in person under SB 276 (2025), upheld by a Montana district court in May 2026; non-photo documents are supplemental proof of address only. Election Day/late registration remains available (SB 490, which would restrict registration hours, is enjoined).
