Madison Eli was elected County Treasurer in 2022. Erin Halverson-Hook became Deputy Treasurer in November 2022. The treasurer is elected every four years.

Real estate tax statements are mailed in December. If you do not receive a tax bill by December 15th, you should contact the Treasurer's Office and request one.
