MONTANA

CONDUCTING A VOTER REGISTRATION DRIVE

Voter Registration Deadlines

  • Applications must be received or postmarked 30 days before any election and received within three days thereafter.
  • “Late registration” is also available and may be completed by an individual in person at county elections offices.
    • Voters may still register after the regular registration deadline until the close of polls on Election Day, except they may not register during the hours of noon to 5:00 p.m. the day before Election Day. Please contact your local election authority for more information about where and when late registration is available in your county.
    • A recently passed law limiting the availability of late registration on Election Day cannot currently be enforced based on a court order. Please check back for more information on this ongoing litigation and the availability of late registration on election day for future elections. Fair Elections Center intends for this information to be used as a general guide and cannot provide legal advice.

Getting Started

Training Requirement: Montana does not require training for registration drives.

Notification and Registration Requirements: Montana does not have notification requirements for registration drives.

Compensation Restrictions: Do not pay registration drive participants based on how many registrations they collect. Do not offer an applicant any incentive of monetary value to register to vote.

Obtaining Applications

State Form: The state mail-in voter registration application can be downloaded from the Secretary of State’s website at sosmt.gov/docs/46/for-montana-voters/59393/montana-voter-registration-application, or obtained from a county elections office, a list of which can be found here: sosmt.gov/elections/election-administrators-contact-list/.

Federal Form: The federal mail-in voter registration application (eac.gov/voters/national-mail-voter-registration-form) may be used in voter registration drives.

Photocopying Blank Forms: Blank applications may be photocopied and used in voter registration drives.

Handling Applications

Incomplete Applications: Do not fill in any missing information on a registration form unless you have express permission from the applicant.

Photocopying Completed Applications: As a best practice, a voter’s full or partial Social Security number and/or driver’s license number should not be retained.

Submitting Completed Applications: State voter registration applications must be delivered or mailed to the county election administrator (sosmt.gov/elections/election-administrators-contact-list/) of the county where the voter resides. Federal voter registration applications must also be delivered or mailed to the county election administrator. They must be submitted by the registration deadline 30 days before Election Day.
