How Property Tax Works

Harding County, South Dakota operates on a property tax system that funds essential local services including schools, county government, and various special districts. Property taxes are the primary source of revenue for these services, with the county collecting taxes on behalf of multiple taxing entities. The effective tax rate in Harding County was approximately 0.50% for the 2024 levy year, though this rate varies significantly depending on your specific location within the county due to different combinations of special taxing districts.

Your actual property tax rate depends on which special taxing districts serve your property, such as school districts, fire districts, and other local improvement districts. Each district adds its own levy to the base county rate, creating variations in total tax rates across different areas of Harding County. Property taxes in South Dakota are assessed annually and collected in two installments, providing a relatively predictable funding stream for local government operations and services.

Section 4

Supplemental Tax Bills

Supplemental taxes in Harding County are triggered when there are changes in property ownership or improvements made to existing properties during the tax year. New construction, additions, or major renovations that increase the assessed value of your property can result in supplemental tax bills. These additional taxes cover the difference between what you originally owed and what you should owe based on the new assessment.

For example, if you complete a $50,000 home addition mid-year, the county assessor will reassess your property and issue a supplemental tax bill for the additional assessed value. The supplemental tax is calculated on a pro-rated basis from the date the improvement was completed through the end of the tax year, ensuring you pay taxes on the increased value for only the portion of the year you benefited from the improvement.

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts for borrowers with less than 20% down payment. Your lender collects 1/12th of your estimated annual property tax bill with each monthly mortgage payment, holding these funds in an escrow account. The lender pays your property taxes directly to Harding County when they become due on April 15th and October 15th each year.

Lenders must provide annual escrow statements showing deposits, payments, and account balances. If your property taxes increase, your lender may adjust your monthly escrow payment and potentially require an escrow shortage payment. Property owners should verify that their lender pays taxes on time, as you remain ultimately responsible for timely payment even when using escrow services. You can verify payments through the South Dakota Property Tax Portal or by contacting the Harding County Treasurer's office directly.
