Montana Election Results 2026: Voting has ended

Yes. When voting in person in Montana an election worker will ask for a current, valid and readable photo ID: a Montana driver's license or REAL ID, Montana state ID card, military ID, tribal photo ID, U.S. passport, Montana concealed carry permit, or a Montana University System/NAIA photo ID. A voter without one of those can show another photo ID together with a document that shows their name and current address, such as a current utility bill, bank statement, paycheck or government check, or other government document. A voter who cannot produce any of these options is directed to the county election official about the provisional voting process.

To vote in Montana you must be registered as required by law, be 18 years old or older on or before the next election, be a citizen of the United States, and have been a resident of Montana for at least 30 days. You cannot vote if you are a convicted felon serving a sentence in a penal institution or have been judged in a court of law to be of unsound mind. Regular registration closes 30 days before an election; during the 30-day late-registration period eligible voters may still register or update their registration at the county election office but must obtain their ballot in person. The Secretary of State's FAQ lists no separate pre-registration age.

In Montana a felony conviction removes the right to vote only while the person is serving a sentence in a penal institution. The Secretary of State's FAQ lists two disqualifications: being a convicted felon serving a sentence in a penal institution, and having been judged in a court of law to be of unsound mind. The FAQ does not list probation, parole or a completed sentence as disqualifying, so a person who is no longer serving a sentence in a penal institution is subject only to the ordinary registration requirements of age, citizenship and 30-day Montana residency.
