Montana Voter Registration Portal

Montana is in the Late Voter Registration period for the Primary Election. You can no longer register to vote by mail if you want to vote in the Primary, but you can submit your form in person.

Simply fill out the form below and we’ll mail you a copy. From there, return it in person to your county election office by no later than 12 pm on June 2 (Election Day.)

Go to your county election office and fill out a voter registration form in person. Bring a valid ID, and make sure you go any day between now and 12 pm on June 2.

Visit your county election office webpage for info on hours of operation. Note that, during the week leading up to Election Day, hours may vary:

Saturday, May 30, from 8-5 pm: All county election offices will be open.
Monday, June 1: No voter registration forms will be accepted or processed.
Tuesday, June 2 (Election Day): You must be in line to register to vote by 12 pm.

You can always check your voter registration status here.

Note: This is NOT an official website of the Montana Secretary of State or any County Election Office.

Filling out this form will NOT automatically register you to vote. You will receive a pre-filled voter registration form to sign and return to your county elections office. *
