How South Dakota property taxes work

South Dakota property taxes pay a year behind, in halves: the first by April 30 and the second by October 31, to the county treasurer. There's no state income tax, so local property tax carries schools and counties.

The assessment calendar is early and quick: the county director of equalization mails assessment notices by March 1 (values as of the prior November), and appeals to your LOCAL board of equalization are due in mid-March, with township/city boards meeting the third week of March and county boards following in April.

The appeal ladder is unusually long — local board, county board, state Office of Hearing Examiners, circuit court — but each rung has a tight deadline measured in days, so the March notice is the trigger to act.

Owner-occupied classification is the everyday saver: a one-time filing gives your home the lower owner-occupied school levy. Seniors and disabled homeowners under income limits can freeze their assessed value entirely, and veterans' exemptions run on top.

When payments are due

Two halves: April 30 and October 31 (for the prior year's taxes).

How to appeal your assessment

The exact filing date shifts slightly with the calendar each year (roughly March 15–22 for local boards) — it's printed on the assessment notice. Miss the local board and the later rungs are closed.

  1. Read your assessment notice (by March 1)It shows the new full value and the appeal instructions with this year's exact dates.

  3. File with your local board by the mid-March deadlineA short written appeal to the city or township board of equalization — free.
  4. Continue to the county board in AprilIf the local board doesn't resolve it, the county board of equalization hears it next.

Common questions

When are property taxes due in South Dakota?
Halves by April 30 and October 31, paid to the county treasurer for the prior year's assessment.
How do I appeal my South Dakota assessment?
Fast, in March: notices mail by March 1, and your written appeal to the local board of equalization is due mid-March (the exact date is on the notice). County boards hear continuations in April; later rungs require hitting the earlier ones.
What is owner-occupied classification?
The filing that puts your home on the lower owner-occupied school levy instead of the higher non-ag rate. One certificate with the county when you buy — new owners who skip it overpay every year.
Does South Dakota freeze assessments for seniors?
Yes — homeowners 65+ or disabled under income and home-value limits can freeze their assessed value with an annual April 1 application through the county treasurer.
Why am I paying 2025 taxes in 2026?
South Dakota bills in arrears: the value set in late 2024 became 2025 taxes payable in 2026. The appeal you file this March affects the bill two springs from now.
