Rate Breakdown

Property taxes in Roberts County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Roberts County

Property taxes in Roberts County are calculated based on the assessed value of your property and the local mill levy. Each year, the County Director of Equalization determines the market value of your property. By state law, this assessment must reflect the full and true market value. Once the total taxable value is established, it is multiplied by the mill levy—a rate set by local taxing jurisdictions, including the county, municipalities, and school districts. Because different areas within the county have different school and municipal requirements, mill rates can vary significantly depending on your specific property location. The final tax amount is the product of your property’s taxable value and the combined mill rate of your taxing district.

Available Exemptions

South Dakota offers several property tax relief programs to assist eligible homeowners in reducing their tax burden. These programs are governed by state statute and administered at the county level:

• Homestead Exemption: Provides a reduction in the taxable value of a primary residence for qualifying seniors and individuals with disabilities.
• Senior Citizens Property Tax Freeze: This program freezes the taxable value of a home for residents who meet specific age (65+) and income requirements, preventing tax increases due to rising property assessments.
• Disability Exemption: Available to individuals who are classified as totally disabled under Social Security guidelines.
• Disabled Veteran Exemption: Offers a significant property tax reduction for veterans who have a service-connected disability rated as 100% permanent and total.

Applicants are encouraged to contact the Roberts County Director of Equalization office to verify eligibility criteria and submission deadlines for these programs.

Payment Schedule & Deadlines

Property taxes in South Dakota are collected annually. Tax statements are typically mailed in the spring, and payments are handled in two installments to assist with financial planning:

• First Half: Due by April 30th.
• Second Half: Due by October 31st.

If you prefer, you may pay the full amount of your property tax in a single installment by the April 30th deadline. Failure to pay by these dates results in the accrual of interest and penalties. Delinquent taxes accrue interest at a rate established by state law, and persistent non-payment can eventually lead to the issuance of a tax certificate and potential tax deed proceedings. It is critical to ensure your payment is postmarked by the deadline to avoid these additional costs.

Appealing Your Assessment

If you believe your property has been incorrectly valued, you have the right to appeal. The process begins with an informal review with the Roberts County Director of Equalization. If the issue remains unresolved, you may formally appeal to the Local Board of Equalization, which typically meets in the spring. If you are still dissatisfied with the decision, you may escalate your appeal to the County Board of Equalization and, subsequently, the state Office of Hearing Examiners. Documentation supporting your valuation claim—such as recent appraisals or sales data of comparable properties—is essential for a successful appeal.
