Valuation limits
South Dakota has no general county-level cap on individual assessed-value increases: real property is assessed annually at full and true/market value and equalized to 85% for taxation. Property-tax levy growth is generally limited by CPI plus growth for taxing entities, with statutory opt-outs. The elderly/disabled assessment freeze is a program-specific valuation freeze subject to its eligibility and 2026 $514,500 full-and-true-value limit.
