Student Voting Guidelines

A registered voter in Colorado is considered a resident of Colorado for motor vehicle registration and operation purposes and for income tax purposes. Federal law prohibits voting in more than one jurisdiction/state.

For out-of-state/new to Colorado students:

  • As noted above, a registered voter in Colorado is considered a resident of Colorado for motor vehicle registration and operation purposes and for income tax purposes.
  • A person residing in Colorado temporarily may want to register to vote in their home state and vote by mail, if their home state allows absentee voting.

For out-of-County students:

  • Colorado law allows college students to keep their voter registration in their hometown and vote by mail from college. This choice is up to the student. They may re-register in the jurisdiction where they are attending school, or they may retain their registration in their hometown. See below for advice on how to have your ballot properly mailed to your dorm.

For Colorado residents attending school out of state:

  • If you intend to keep Colorado as your permanent home for motor vehicle and income tax purposes, register as a Colorado voter and make sure your voter registration is up-to-date with your out-of-state mailing address. Your residential address is your Colorado home address.

Before registering to vote, please review the Voter Registration Requirements and Information.
