The county treasurer’s offices statewide are responsible for transactions to license and title motor vehicle and to help with the recording and cancelling of liens. The money from licensing is used to maintain your local roads and bridges. The money from the taxation of these vehicles is collected and remitted to the state of South Dakota. Access is available on this site to SDCars.org to view forms and online licensing. The county treasurer also collects property taxes for the county, city, school districts, and any other political district authorized to levy real estate taxes. Taxes are based on the value and mill levies. Paying and viewing property taxes is also available through this site. Please read the information about fees that will apply to the transaction. The treasurer’s office also administers tax aid to low-income and/or elderly families.
