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.

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 registrations, titles, and drivers licensing.  The Treasurers Office also releases and notates motor vehicle liens and assists taxpayers in applying for duplicate titles. 

Registration is on a staggered licensing system based on the first letter of the owner's last name.  Find the first letter of your last name in the table below to determine which month your vehicle licenses will expire.
