How Property Tax Works

Stanley County, South Dakota operates under a property tax system that funds essential local services including schools, county government operations, road maintenance, and emergency services. Property taxes in Stanley County are calculated based on assessed value multiplied by the applicable tax rate, which varies significantly by location within the county due to different combinations of special taxing districts.

The effective tax rate in Stanley County is approximately 0.50% for the 2025 levy year, though this varies considerably depending on which school district, fire district, and other special taxing districts serve your specific property location. Property assessments are conducted annually by the Stanley County Assessor's office, with assessed values typically reflecting a percentage of market value. Property owners should note that various tax credits may be available to reduce their tax liability, but these require separate applications and are not automatically applied.

Section 4

Supplemental Tax Bills

Supplemental taxes in Stanley County are triggered by changes in property ownership, new construction, or improvements that increase a property's assessed value during the tax year. When these changes occur, the county assessor calculates the difference between the new assessed value and the original assessment, then applies the current tax rate to determine additional taxes owed.

For example, if you complete a $50,000 home addition in March and your property is reassessed from $200,000 to $250,000, you would owe supplemental taxes on the $50,000 increase prorated from the completion date through the end of the tax year. These supplemental bills are typically issued within 30-60 days of the assessment change and have separate due dates from your regular property tax payments.

Escrow & Property Taxes

Most mortgage lenders in Stanley County require borrowers to maintain an escrow account for property tax payments. Lenders collect monthly escrow payments along with your mortgage payment, then pay your property taxes directly to Stanley County when due. The monthly escrow amount is calculated by dividing your annual property tax bill by 12, often with an additional cushion for potential tax increases.

Property taxes in Stanley County were due October 31, 2025, and lenders typically make payments by this deadline to avoid penalties. The County Treasurer's office has been actively contacting property owners about the October 31st deadline. Property owners should verify that their lender has made timely payments and review their annual escrow analysis to ensure adequate funds are being collected for the following year's taxes.
