The Treasurer is elected to a four-year term and officially assumes the office the first Monday in January.

The Treasurer's Office is the property tax collector for the County of Sully, City of Onida, Agar Town, the School Districts located in Sully County, the State of South Dakota and other taxing districts within Sully County. Real Estate taxes are due and payable in the Treasurer's Office January 1. The lst half of real estate taxes become delinquent May 1st and the second half of real estate taxes become delinquent November 1. If real estate taxes are not paid by December 1, these taxes will be advertised. The Treasurer conducts a tax certificate sale on the 3rd Monday in December. 

As the "banker" for Sully County, the Treasurer's Office is also responsible for collecting all other money other county departments collect such as fees for services, licenses, miscellaneous revenue and special assessments. The Treasurer assures the legality and propriety of disbursements and invests surplus monies until they are needed for essential county operations. 

Our office also handles a variety of public services for residents of Sully County such as vehicle registration and titles, drivers licensing, resident game and fish license and application. The Treasurers Office also releases and notates motor vehicle liens and assist taxpayers in applying for duplicate titles. 

Registration is on a staggered licensing system based on the first letter of the owner's last name. Vehicles not in the staggered system are boats, commercial vehicles, house trailers and snowmobiles. Find the first letter of your last name in the table below to determine which month your vehicle licenses will expire. Vehicle owners must provide either the South Dakota driver's license number or Social Security number of all registered owners on the title before the license may be renewed. 

If you have purchased a vehicle that was previously licensed by another person, you may have to renew your plates at a different time. In that situation, you should not assume that your license plates expire in your renewal month. South Dakota residents have 30 days from the date of purchase of a new or used motor vehicle to transfer title into their name. A penalty of $1 per week up to 26 weeks will be assessed for late transfers. The penalty for a transfer after 26 weeks is $50.
In lieu of sales and use taxes, a 3% excise tax is imposed on most motor vehicle transactions unless exempt. The excise tax is based on the purchase price of the motor vehicle. In some instances, vehicles eleven or more years old may be subject to excise tax, but, currently, all motor vehicles less than eleven years old are taxed, regardless of purchase price. Credit is given for trade-ins.
