Property Taxes in South Dakota: Rates, Exemptions, and How They Work (2026)
TL;DR
South Dakota has no state income tax, making property taxes an important revenue source. The average effective rate is about 1.08%. Property is assessed at 85% of market value (the "productivity" level established by law). The owner-occupied assessment freeze limits annual assessment increases. The state offers a sales tax rebate for the elderly and disabled. County Directors of Equalization handle assessments. Appeal to the local Board of Equalization within 30 days of the notice of assessment.
Assessment
South Dakota assesses property at 85% of full and true market value. Non-agricultural property is assessed at the full and true value, but counties apply a sales ratio factor. Agricultural land uses a productivity-based valuation.
Assessment Freeze
Owner-occupied single-family residential properties have annual assessment increases limited (the exact mechanism varies by recent legislative action). The freeze applies to the assessed value of the dwelling only, not the land.
Exemptions
| Program | Benefit | Who Qualifies |
|---|---|---|
| Owner-Occupied Dwelling Tax Reduction | Reduces assessment | Owner-occupied primary residence |
| Property Tax Reduction (elderly/disabled) | Freeze or reduction in tax | Varies by income and property value |
| Disabled Veteran | Full exemption on first $150,000 of value | 100% disabled veterans |
| Sales/Property Tax Refund | Up to $1,380 refund | 65+ or disabled, income limits |
Appeal
- Local Board of Equalization: File within 30 days of notice (typically March)
- County Board of Equalization: Next level if unresolved
- Circuit Court: Judicial appeal within 30 days
