Rate Breakdown

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

How Property Tax Works in Sanborn County

Property tax in Sanborn County is primarily determined by the assessed value of your property and the local millage rate (also known as the tax levy). The process begins with the County Director of Equalization, who determines the "full and true" market value of your property. By state law, this assessment is intended to reflect the current market value of your land and improvements.

Once the total assessed value is established, the local taxing entities—which include the county, municipalities, and school districts—set their budgets. These budgets are divided by the total taxable valuation of the jurisdiction to establish a mill levy. Your final tax bill is calculated by multiplying your property’s taxable value by the combined mill rate of your specific taxing district. Because mill rates fluctuate annually based on budget requirements, your total tax burden may change even if your property's assessed value remains stable.

Available Exemptions

South Dakota offers several property tax relief programs designed to assist specific residents in reducing their tax liability. These programs are governed by state statute and administered at the county level:

• Homestead Exemption: Generally refers to the classification of owner-occupied property, which often benefits from a lower school district tax levy compared to non-residential property.
• Senior Citizen/Disabled Persons Property Tax Freeze: Qualified low-income seniors (age 66+) or individuals with a permanent disability may apply to have the valuation of their home "frozen" at the amount assessed in the year they qualify, preventing tax increases on that base value.
• Disabled Veteran Exemption: Veterans who have been rated as 100% disabled due to a service-connected injury may qualify for a significant reduction in property taxes on their primary residence.

Payment Schedule & Deadlines

Property taxes in Sanborn County are billed annually and are payable in two equal installments. It is essential to adhere to these statutory deadlines to avoid penalties:

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

If the first half is not paid by the April 30th deadline, the entire annual tax amount becomes delinquent. Late payments are subject to interest charges as prescribed by South Dakota law. If taxes remain unpaid for an extended period, the county may initiate a tax deed process, which can lead to the loss of the property. Please ensure payments are postmarked or received by the Sanborn County Treasurer by the close of business on the due date.

Appealing Your Assessment

If you believe your property has been assessed incorrectly or unfairly compared to similar properties, you have the right to appeal. The process begins with the Local Board of Equalization, usually held in the spring. You must provide evidence, such as recent appraisals or documentation of comparable sales, to justify a change in value. If you are dissatisfied with the local board's decision, you may further appeal to the Sanborn County Board of Equalization and, subsequently, to the State Board of Equalization or the circuit court.
