Absentee Voting

Can't make it to the polls on Election Day? Here's how to request, complete, and return an absentee ballot in South Dakota.

How It Works

Requesting your ballot

  • Make sure you're registered to vote first — check anytime at the Voter Information Portal.
  • Download and print the absentee ballot application, then mail your original, signed application to your county election official. Only voters covered under the Uniformed and Overseas Absentee Voting Act may submit an application by fax or email.
  • Once absentee voting opens, you can also apply and vote in person at your county auditor's office — bring a valid photo ID, or sign a personal identification affidavit if you don't have one.
  • If you register or apply using a mail-forwarding service, commercial mail box, or PO box as your address without describing where you actually live, you'll be designated a federal voter.

Timing

Key deadlines

In Person

Apply at the auditor's office

You can apply for an absentee ballot in person any time before an election, up until 5:00 p.m. the day before Election Day.

By Mail

Returning your ballot

Your voted ballot must reach your County Election Official in time to be delivered to your precinct before the polls close on Election Day.

Homebound

Authorized messenger

If illness or disability keeps you confined, you can apply in writing for a messenger to deliver and return your ballot. The request must reach election officials by 3:00 p.m. on Election Day.

Primary

Independent / NPA Voters

Registered Independent/NPA voters requesting a primary ballot may choose a Democratic ballot or a Non-Political ballot (local, nonpartisan races only). If you don't mark a choice, you'll receive the Non-Political ballot — and if none is available, you won't receive a ballot at all.

Also Useful

Vote by mail, the federal way

The U.S. Postal Service runs its own election mail resource for voters and officials using the mail to vote.
