Voter information

How the primary works

A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Wisconsin utilizes an open primary system; registered voters do not have to be members of a party to vote in that party's primary.[1][2]

For information about which offices are nominated via primary election, see this article.

Poll times

In Wisconsin, polls are open from 7 a.m. to 8 p.m. Central Time. An individual who is in line at the time polls close must be allowed to vote.[3]

Registration requirements

Check your voter registration status here.

To register to vote in Wisconsin, one must be a citizen of the United States and a resident of Wisconsin for at least 28 days prior to the election. A voter must be at least 18 years of age by Election Day.[4]

Prospective voters can register online or by mailing a form to their municipal clerk. If registering by mail, the application must be postmarked no later than 20 days before the election. In-person registration must be completed by 5 p.m. on the Friday before Election Day. Prospective voters can also register in person at their municipal clerk's office up until the Friday before the election or at their polling place on Election Day. (Same-day voter registration requires proof of residency.)[4]

Automatic registration

Wisconsin does not practice automatic voter registration.[5]

Online registration

See also: Online voter registration

Wisconsin has implemented an online voter registration system. Residents can register to vote by visiting this website.[5]

Same-day registration

Wisconsin allows same-day voter registration.[5]

Residency requirements

Wisconsin law requires 28 days of residency in a precinct before a person may vote.[4]

Verification of citizenship

See also: Laws permitting noncitizens to vote in the United States

Wisconsin does not require proof of citizenship for voter registration. An individual must attest that they are a U.S. citizen when registering to vote. According to the state's voter registration application, a voter who provides false information "may be subject to fine or imprisonment under State and Federal laws."[6]

All 49 states with voter registration systems require applicants to declare that they are U.S. citizens in order to register to vote in state and federal elections, under penalty of perjury or other punishment.[7] Seven states — Alabama, Arizona, Georgia, Kansas, Louisiana, New Hampshire, and Wyoming — have laws requiring verification of citizenship at the time of voter registration, whether in effect or not. One state, Ohio, requires proof of citizenship only when registering to vote at a Bureau of Motor Vehicles facility. In three states — California, Maryland, and Vermont — at least one local jurisdiction allows noncitizens to vote in some local elections. Noncitizens registering to vote in those elections must complete a voter registration application provided by the local jurisdiction and are not eligible to register as state or federal voters.

Verifying your registration

The site My Vote, run by the Wisconsin Election Commission, allows residents to check their voter registration status online.

Voter ID requirements

Wisconsin requires voters to present photo identification while voting.[8]

The following list of accepted ID was current as of October 2025. Click here for the Wisconsin Election Commission's page on accepted ID to ensure you have the most current information.

  • Wisconsin Department of Transportation-issued driver license, even if driving privileges are revoked or suspended
  • Wisconsin Department of Transportation-issued identification card, with or without a photo
  • Veteran ID card or U.S. Uniformed Service ID card
  • U.S. passport book or card
  • Identification card issued by a federally recognized Indian tribe in Wisconsin
  • Photo identification card issued by a Wisconsin accredited university, college, or technical college, containing the date the card was issued, an expiration date, and a signature. (If expired, the voter must also provide a separate document proving enrollment)
  • Certificate of naturalization issued within the past two years
  • Driver’s license receipt issued by Wisconsin Department of Transportation (valid for 45 days from date issued)
  • Identification card receipt issued by Wisconsin Department of Transportation (valid for 45 days from date issued)
  • Wisconsin Department of Motor Vehicles ID Petition Process Photo Receipt (valid for 60 days from date issued)

The following voters do not need to provide photo ID:[8]

  • Confidential electors
  • Active military and permanent overseas voters who vote by absentee ballot
  • Indefinitely confined voters who vote by absentee ballot

Voters can obtain a free Wisconsin State ID Card at a Wisconsin Division of Motor Vehicles office. Voters need the following to apply for an ID:[9]

  • Proof of name and date of birth (such as a birth certificate)
  • Proof of identity (Social Security Card, Medicaid/Medicare Card, etc.)
  • Proof of Wisconsin residency (utility bill, government mail, lease, etc.)
  • Proof of U.S. citizenship (U.S. Birth certificate or citizenship paperwork)
  • Social Security Number

Voters who do not have all or any of the materials listed above can still obtain an ID. Call the voter ID hotline for assistance at (844) 588-1069.[9]

Early voting

Wisconsin permits early voting. Learn more by visiting this website.

Early voting permits citizens to cast ballots in person at a polling place prior to an election. In states that permit no-excuse early voting, a voter does not have to provide an excuse for being unable to vote on Election Day. States that allow voters to cast no-excuse absentee/mail-in ballots in person are counted as no-excuse early voting states.

Forty-seven states and the District of Columbia permit no-excuse early voting.

Absentee voting

All voters are eligible to vote absentee/by mail in Wisconsin. There are no special eligibility requirements for voting absentee/by mail.[10][11]

To vote absentee by mail, a request to the municipal clerk must be received by 5 p.m. on the Thursday before Election Day. Once completed, returned ballots must be received no later than 8 p.m. on Election Day.[10][12]

According to the U.S. Department of Justice, the application "may require only the minimum amount of information necessary to prevent duplicate voter registrations and permit State officials both to determine the eligibility of the applicant to vote and to administer the voting process."
