Register at School or Home

Students have a decision about where to register to vote.

You have a right to register to vote at the address you consider the place where you live, whether that is your family's home or the place where you attend school. You should update your registration anytime this home address changes.

You may only be registered and vote in one location.

What Type of ID Do I Need to Register?

Montana’s voter registration form asks for your Montana driver’s license or ID number, or the last four digits of your Social Security number. Be sure to provide one of these numbers if you have it.

Common Questions/Concerns

Registering to Vote Does Not Affect Your:

Federal Financial Aid

Where you register to vote will not affect federal financial aid such as Pell Grants, Perkins or Stafford loans, or your dependency status for FAFSA.

Status as a Dependent on Your Parents’ Taxes

Being registered to vote at a different address from your parents does not prevent them from claiming you as a dependent on their taxes.

Tuition Status

Being deemed out-of-state for tuition purposes does not prevent you from choosing to register to vote in your campus community.


Will registering to vote in Montana affect my driver’s license or car registration?

As a new resident of Montana, you may be required to obtain a Montana driver's license and update your car's registation regardless of whether you register to vote there. For more information, you many wish to contact the Motor Vehicle Division of the Montana Department of Justice.
