Register to Vote

How to Register to Vote in Montana

To vote, you must go to your county election office and register there during the late registration timeframe up to and including Election Day. Visit your county election office on weekdays between of 8 am and 5 pm and complete a registration form.

If you are not registered and do not care to vote, you may download this form and mail it in to the election office in the county in which you reside. You will then be registered for future elections.

Fill out a registration form and mail it to the local election office. There is also a registration form available in your phone book. Mail it or drop it off at your local election office. The registration form must be returned to the local election office at least 30 days before election day OR you will have to LATE REGISTER in person at your county election office.

Fill out a registration form when you apply for or renew your driver’s license.

Make sure you’re eligible to vote.

You will need to provide identification when you register. Acceptable forms of identification are listed on the voter registration application.

When you fill out your registration form, do not list a post office box as your residence. If you don’t have a street address, describe the location of your residence. Use cross streets, for example, or list the section, township, and range.

Once you’ve registered, you’ll get a voter confirmation notice from your local election office verifying your registration and telling you which precinct you vote in.

Registration is generally permanent unless you do not vote in a federal general election AND do not respond to confirmation mailings. If you don’t vote in a federal general election and do not respond to the mailings, your name will be placed on an inactive voter list. If you are placed on the inactive voter list, you will NOT automatically receive a ballot in a mail-only election. If you fail to vote in two federal general elections after the mailings are sent, your name will be removed from the voter rolls and you will have to re-register to vote in Montana. Check your voter registration here.

Be sure to keep your registration current by filling out a new card from your local election office if you change your address or your name. If you move to a different county, you will need to register again in that county.

Late Voter Registration:

The deadline for regular registration is 30 days before any election. If you miss that deadline, you can still register and vote in the election at your county election office. You can late-register and vote right up until close of polls on election day. No ballots are issued between noon and 5 pm the day before the election, however, so if you haven’t registered before then, you probably want to wait until election day to register and vote. If you want to avoid the possibility of long lines, plan to register by the close of regular registration or as soon as possible after the start of the late registration period.


You may vote only in the precinct in which your residence is located. If you’re a student living at school and a Montana resident, you can choose whether to register to vote at home or school, but you can’t register or vote in both places. If you are an out-of-state student going to school in Montana, you can choose to become a resident of Montana if you have resided in Montana for at least 30 days, and register and vote in the county where you are going to school.

Absent Military and Overseas Voters:

Registering to vote and requesting absentee ballots in Montana is easy for out-of-state military and overseas electors. The best form to use to do so is the Federal Post Card Application form. This form is used both for voter registration and to request absentee ballots for all the state and local elections in the calendar year in which it is requested and the following two federal elections. For more information, visit the Montana SOS web site.
