If you’re sitting there wondering when does early voting start in South Dakota, you aren't alone. It’s a bit of a trick question. Technically, South Dakota law doesn't use the phrase "early voting" in the way some other states do. Instead, we have "in-person absentee voting."
Basically, it's the same thing for you, the voter. You walk into an office, you cast your ballot, and you go home. No excuses needed. No doctor's note required.
For the 2026 Primary Election, you can start heading to the polls on April 17, 2026. If you are looking toward the General Election in the fall, the magic date is September 18, 2026.
The 46-Day Window
South Dakota is actually one of the most generous states in the country when it comes to the timeline. We get 46 days. That is a massive chunk of time. While other states are bickering over a single week of early access, South Dakotans have over a month and a half to get it done.
The law behind this is SDCL 12-19-1.2. It’s pretty straightforward. It mandates that ballots must be available nearly seven weeks before the actual Election Day.
Why the Date Matters for 2026
Early voting matters because life happens. Planting season might run late. A freak October blizzard could roll through—honestly, it's happened before. By knowing exactly when does early voting start in South Dakota, you give yourself a massive safety net.
You don’t have to wait for a specific "early voting site" to open up like they do in Florida or New York. In South Dakota, your "site" is typically your County Auditor’s office. They handle the heavy lifting.

How to Actually Do It
It’s surprisingly chill. You just show up at your County Auditor’s office during their regular business hours. Most are open 8:00 AM to 5:00 PM, but if you live in a smaller county, it’s worth a quick phone call to make sure they aren't out for a long lunch.
You’ll need to bring a photo ID. A South Dakota driver’s license is the gold standard. They also accept tribal IDs, passports, or even student IDs from South Dakota high schools or colleges.
If you forget your ID? Don't panic. You can sign a personal identification affidavit. It basically says, "I am who I say I am," under penalty of perjury. You can still vote.
The Absentee-by-Mail Loophole
Some people confuse "early voting" with "absentee voting by mail." In South Dakota, they are two sides of the same coin.
If you want the ballot sent to your house, you have to mail an application to your County Auditor first. You can’t just call them. You have to print a form, sign it, and either get it notarized or attach a photocopy of your ID.

Once they get that, they’ll mail you the ballot starting on those same dates: April 17 or September 18.
Common Misconceptions
People often think there are "special" early voting locations at the grocery store or the mall. Usually, that's not the case here. It’s almost always the Auditor’s office.
Another big one: people think you need a "reason" to vote early. Nope. South Dakota is a "no-excuse" state. You could be perfectly healthy and in town on Election Day but just prefer to vote on a Tuesday three weeks early because the lines are shorter. That is perfectly legal.
Important Deadlines to Watch
While the start date is a big deal, the "cutoff" is just as vital. You can vote in person right up until 5:00 PM the day before the election.
- Primary Cutoff: June 1, 2026
- General Cutoff: November 2, 2026
If you are mailing your ballot back, it must reach the Auditor by the time the polls close on Election Day (7:00 PM). If it arrives the next day, it doesn’t count. The postmark doesn't save you here—it's all about when it physically lands in their hands.
Actionable Next Steps
- Check your registration. Go to the South Dakota Secretary of State website and use the "Voter Information Portal." If you've moved since the last election, you need to re-register.
- Locate your Auditor. If you don't know where your County Auditor is, find out now. Most are in the county courthouse.
- Decide your method. If you want to vote from your couch, request that mail-in ballot at least two weeks before the election to account for the mail being, well, the mail.
- Set a calendar alert. Put "September 18 - Early Voting Starts" in your phone right now.
Early voting is the best way to ensure your voice is heard without the stress of Election Day crowds. Now that you know when does early voting start in South Dakota, you've got no excuses left.
