Include a copy of your current South Dakota driver’s license number or nondriver ID number, or the last four digits of your Social Security number.

How to request an absentee ballot

Any registered voter in the state can request an absentee ballot.

Apply by mail, in person or using an authorized messenger, if eligible.

  • By mail: Download and complete an absentee ballot application form. Mail your original, signed application to your county auditor's office. Attach a copy of an acceptable form of ID — such as a South Dakota driver’s license, a South Dakota nondriver ID card, passport or tribal photo ID — to your application form. Or complete a notarized oath on the form (Section 7) swearing the information is true and correct.
  • In person: Fill out an absentee ballot application form at your county auditor’s office. Bring an acceptable form of ID. You can complete your absentee ballot application, receive a ballot and mark your ballot on the same visit. 
  • Using an authorized messenger: If sickness or disability keeps you from the polls, you can apply for an absentee ballot via an authorized messenger. The authorized messenger may pick up and return your ballot to the county auditor for you. Download, print and complete the absentee ballot application form, including the authorized messenger request section. Authorized messengers must let their county auditor’s office know if they are delivering ballots for more than one person.

Your application is due by mail or in person by 5 p.m. on Monday, Nov. 4 (not just postmarked by this date). Applications to vote via an authorized messenger are due by 3 p.m. on Tuesday, Nov. 5. Ballots are mailed within 48 hours of an application’s receipt.

Only voters covered under the Uniformed and Overseas Citizens Absentee Voting Act can submit their application for an absentee ballot via fax or email.

Returning an absentee ballot


Mark your ballot and place it in the return envelope. Sign your name on the reverse side of the return envelope. Return your completed absentee ballot:

  • By mail: Follow the instructions that accompany your absentee ballot, then mail your ballot with proper postage to your county auditor’s office

Completed absentee ballots must be received on Tuesday, Nov. 5, (not just postmarked by that date) with sufficient time for election officials to deliver them to the corresponding polling locations before the polls close.

Track your ballot using the state’s voter portal.

Voting in person before Election Day

South Dakota doesn’t offer early in-person voting, but you can go to your county auditor's office to complete and submit an absentee ballot in person from Friday, Sept. 20, through Monday, Nov. 4.

Voting at the polls on Election Day

Use the state’s voter portal to find your polling place. Polls are open from 7 a.m. to 7 p.m.

Sample ballots will be available on the state’s voter portal.

Voter ID requirements on Election Day

All voters applying for an absentee ballot or voting at a polling place on Election Day need to show an approved photo ID, such as a state-issued driver’s license, state-issued student ID, U.S. passport or tribal ID.

If you do not have an approved photo ID while voting in-person absentee or at the polls, you may complete a personal identification affidavit and still vote a regular ballot. This affidavit may not be used as a substitute for the ID requirements for the absentee ballot application.

Voting with a disability

Voters have the option to use the ExpressVote machine, which shows an electronic version of the ballot on a screen. The machine also can read the ballot to you. You can mark your ballot using the touch screen or keypad.

Voters who live in nursing homes or long-term care facilities can vote using an absentee ballot and use an authorized messenger, if needed.
