About Property Taxes in South Dakota
South Dakota property taxes are administered at the county level. Property is assessed at its full and true value (market value) as of November 1 of the prior year. South Dakota has no state income tax, which means property taxes are an important funding source for local governments and schools. South Dakota offers meaningful relief programs for seniors and veterans, and has no sales tax on groceries, which partially offsets the property tax burden. Tax bills are mailed in the spring and due in two installments.
Payment & Assessment
South Dakota property taxes are paid in two equal installments: First half: Due April 30 Second half: Due October 31 A 10% penalty applies to late payments. After two years of non-payment, taxes may be sold. Most counties offer online payment. Contact your county treasurer for payment options.
