All municipalities in Wisconsin require voter registration prior to a person being allowed to vote. If you move your residence or change your name, you are also required to update your voter registration information. In addition, state law requires that an individual live within their community a minimum of 28 days prior to registration.

There are four ways to register:

• Online: My Vote allows eligible Wisconsin voters to register to vote. Please fill in the information as instructed, printout, sign and either mail in, or drop off at their municipal clerk’s office, or at their polling place on Election Day.
• By mail: Download the Voter Registration Application and mail it to Diane Coenen, City Clerk, 174 East Wisconsin Avenue, Oconomowoc, Wisconsin 53066. The application must be postmarked no later than the 20th day (third Wednesday) before the election. A first-time voter (one who has not voted in an election in Wisconsin) submitting a registration application by mail must include a copy of their proof of residence (see below) if it is after the deadline.
• In person: Register in the municipal clerk's office up to 5:00 pm or the close of business whichever is later on the Friday before the election. Note: After the by mail deadline, an elector registering in person in the Clerk's Office is required to present acceptable proof of residence as outlined below.
