South Dakota starts with full market value and a March local-board appeal, followed by county review in April.
- The property would not sell for the assessed value.
- The property is assessed unequally or its record is wrong.
- The complaint is about the tax amount rather than value.
- You miss the annual local deadline.
Read the full explanation
South Dakota assesses property at full and true market value, then applies a statewide equalization factor for tax purposes. An owner first appeals to the local board of equalization in March, then may appeal to the county board in April. Exact dates depend on the calendar and whether the property is inside a municipality, so use the annual county schedule. This is general information, not tax advice.
