Wisconsin LLC Formation
Form an LLC in Wisconsin: Fees, Deadlines & What to File
The state filing is only the starting point — here's what forming an LLC in Wisconsin actually costs, and what else you need beyond the state paperwork to be properly protected.
State Filing Fee
$130
Paid once, when your formation document is filed with the state.
Annual Fee
$25
Due during your formation anniversary quarter.
What the state filing actually covers
Filing your formation document with Wisconsin creates your LLC as a legal entity — but the state filing alone doesn't cover the internal terms that actually govern how your business runs, what happens if a member leaves, or how ownership and profits are split. That's the job of your operating agreement, which Wisconsin doesn't require you to file but which governs everything the state filing doesn't address.
What you still need beyond the state paperwork
An Operating Agreement
Ownership splits, voting rights, and buyout terms — the document that actually governs disputes.
A Registered Agent
A person or service with a Wisconsin address to receive legal notices on the LLC's behalf.
An EIN
Needed to open a business bank account and hire, sequenced correctly against your Wisconsin formation date.
Ongoing Compliance
Your annual $25 fee, due during your formation anniversary quarter.
Get your Wisconsin operating agreement drafted
A licensed attorney drafts your operating agreement around Wisconsin's specific default rules — not a generic 50-state template.
