2020 Election Voting Guide

The opportunity to make your voice heard at the ballot box is right around the corner. Please note  11 Montana counties are conducting polling place elections and 45 are holding all mail ballot elections.  

Visit VoteinMT.org to find out everything you need to cast your ballot by 8 p.m. on Tuesday, November 3 including  how to find and contact your county election office.  

We encourage you to complete and return your ballot as quickly as possible. If you would like to return your ballot via mail, you should do so no later than October 27 to ensure it arrives before Election Day (Tuesday, Nov 3). You may also return your completed ballot in person at your county elections office or designated drop box location.  

Whether you return your ballot by mail or in person, it must be received by your county elections office by 8 p.m. on Election Day. 

Important Deadlines


Regular Voter Registration Deadline

Last day for regular voter registration. After this date, voters must register in-person at their county election office or designated county polling location(s).


Recommended Ballot Mailing Deadline

To ensure that your mail-in ballot is received by 8 pm on Election Day, we strongly recommend sending your ballot in by this day. Be sure to use your typical signature; ballot signatures that do not match the signature on your voter registration may be rejected.


Election Day

If you are voting
in-person, head to your county’s polling site(s). If you have not yet sent in your ballot, remember that it should be received by your county elections office no later than 8 p.m.

Visit the Secretary of State’s My Voter Page to check that your ballot has been received and accepted. Ballots may be rejected for easily fixed reasons, such as a missing signature. Complete a ballot rejection notice form and submit it, along with a copy of your ID, to your county election office by this date by Wednesday, November 4.
