You must send a copy your South Dakota photo ID with your absentee ballot application. Check our Voter ID Laws page for a list of acceptable forms of ID. If you can't get a copy of an acceptable form of photo ID, then you must have your absentee ballot application signed and notarized by an authorized witness.

South Dakota absentee ballot directions

  1. Use our Absentee Ballot Tool to prepare your application.
  2. Sign and date the form. This is very important!
  3. Return your completed application to your Local Election Office as soon as possible. We'll provide the mailing address for you.
  4. All Local Election Offices will accept mailed or hand-delivered forms. If it's close to the deadline, call and see if your Local Election Office will let you fax or email the application.
  5. Make sure your application is received by the deadline. Your application must actually arrive by this time -- simply being postmarked by the deadline is insufficient.
  6. Please contact your Local Election Office if you have any further questions about the exact process.

Once you receive your ballot...

  1. Once you receive the ballot, carefully read and follow the instructions.
  2. Sign and date where indicated.
  3. Mark the ballot in the presence of two witnesses (or one witness if the witness is a notary public).
  4. Seal the ballot and complete the Absentee Application and Certificate on the back of the envelope.
  5. Have the witness(es) complete and sign the Witnesses' Certification portion of the envelope.
  6. Mail your voted ballot back to the address indicated on the return envelope.
  7. Your voted ballot must arrive by the deadline or it will not be counted.
