Registration and ways to vote

Choose the voting method that works for you. Deadlines depend on that method. Check the time and delivery requirements, not just the date. Military, overseas, and emergency voting may have separate rules.

01

Register

Submit an original signed paper registration form to your county auditor or an authorized registration location. South Dakota does not offer online voter registration. Confirm registration before requesting a ballot.

  • In-person registration receipt deadline

    Your county auditor must receive your signed registration by 5 p.m. October 19. A postmark alone does not satisfy the deadline.
