Felony Information

Under Montana law, if you have been convicted of a felony, you may not vote if you are incarcerated, but you may register and vote while you are on probation or parole. For more information on voting after a felony conviction, visit the Montana Elections and Government Services Division's website, or call them at 406-444-4732.

Information for Students

  • You must be a resident of the state in which you register and vote. If you're a student from Montana who attends school in another state, you may need to determine whether you're a Montana resident or a resident of the state where you attend school. The important thing to keep in mind is that you may only cast your vote in one state.
  • Here's what Montana says about residency: Your residence is the place where your habitation is fixed, and where you return to whenever you're away.
  • If you determine you're a Montana resident, but will not be present in this state or will be away from your home district on Election Day, be sure to check the absentee ballot application requirements and deadlines. In addition, Montana residents who attend school in-state, but in a different election district, may be eligible to register and vote in the election district where they live while attending school.
  • To determine whether you're a resident of a different state where you attend school, be sure to check that state's residency requirements.
