What Wisconsin requires of your registered agent (Department of Financial Institutions (DFI))

Every LLC must name a registered agent with an in-state street address.

A Wisconsin resident, or a business entity formed in Wisconsin or authorized there, whose business office is the registered office. The agent needs an email address and has to consent. Statute behind it: Wis. Stat. § 183.0115.

The address has to be an actual physical location with a street address in Wisconsin, not solely a P.O. box, mailbox service or answering service.

The state's wording: docs.legis.wisconsin.gov (we looked on October 2026, so you can too)

State fees only

Qualifying owners pay nothing extra to go without a service. The prices above, $99 to $149 a year, buy you convenience.
