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.

As a new resident of Missouri, you may be required to obtain a Missouri driver’s license or update your car registration, regardless of whether you registered to vote there. For more information, you may wish to contact the Missouri Department of Revenue.
