How to form your Wisconsin LLC
Step1
Step 1: Pick the LLC's name
A quick search of the state's business records tells you whether the name is free.
TipHave a second choice ready.
Step2
Step 2: Line up your registered agent
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.
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.
If you file yourself, budget $130. If a service files, add $199; our picks are ranked above.

Write down who owns the Wisconsin LLC and how decisions are made. This operating agreement stays with your records, not with the state.

Step 7: Keep the LLC active
Mark the annual report in your calendar: every year, due end of the calendar quarter containing the LLC's anniversary date, fee $25. If you miss it: $25.
