To register to vote in South Dakota, an applicant must be a citizen of the United States, a resident of South Dakota, and at least 18 years old by the day of the next election.[1]
The deadline to register to vote is 15 days before the next election. To register, an applicant may submit a voter registration form to the county auditor. Prospective voters can also register in person at the county auditor's office, driver's license stations, certain public assistance agencies, or military recruitment offices.[1]
In-person voting[edit]
Poll times[edit]
See also: State poll opening and closing times
In South Dakota, all polls are open from 7 a.m. to 7 p.m. If the polls close while you are still in line, you will be permitted to vote. South Dakota is divided between Central and Mountain time zones.[2]
Voter identification[edit]
See also: Voter identification laws by state
South Dakota requires voters to present photo identification while voting.[3]
The following were accepted forms of identification as of October 2025. Click here for the South Dakota Secretary of State's page on accepted ID to ensure you have the most current information.
South Dakota driver's license or nondriver ID card
U.S. government photo ID
U.S. passport
U.S. Armed Forces ID
Current student photo identification card from a South Dakota high school or South Dakota-accredited institution of higher education
Tribal photo ID
If a voter does not have a photo ID, he or she can sign a personal identification affidavit. The voter will then be given a regular ballot.[3]
Early voting[edit]
See also: Early voting
South Dakota permits early voting. Learn more by visiting this website.
Early voting permits citizens to cast ballots in person at a polling place prior to an election. In states that permit no-excuse early voting, a voter does not have to provide an excuse for being unable to vote on Election Day. States that allow voters to cast no-excuse absentee/mail-in ballots in person are counted as no-excuse early voting states.
Forty-seven states and the District of Columbia permit no-excuse early voting.
Absentee/mail-in voting[edit]
See also: Absentee/mail-in voting
All voters are eligible to vote absentee in South Dakota. There are no special eligibility requirements for voting absentee.[4][5]
To vote absentee, an absentee ballot application must be received by county election officials no later than 5 p.m. the day before the election. A completed absentee ballot must then be received by election officials by the close of polls on Election Day.[6]

Voting rules for people convicted of a felony[edit]
See also: Voting rights for people convicted of a felony
According to the South Dakota Secretary of State's office, "a person currently serving a felony conviction in either federal or state court shall be removed from the voter registration records. A person so disqualified becomes eligible to register to vote upon completion of his or her sentence. A person who receives a suspended imposition of sentence does not lose the right to vote."[7]
Voting rights for people convicted of a felony vary from state to state. In the majority of states, people convicted of a felony cannot vote while they are incarcerated but may regain the right to vote upon release from prison or at some point thereafter.[8]
