How to Start an LLC in Wisconsin

Your Wisconsin LLC name must be unique among all businesses registered with the Wisconsin Department of Financial Institutions and must include a required designator.

Wisconsin Naming Rules:

• Must include: "Limited Liability Company," "LLC," or "L.L.C."
• Cannot use: Words implying a government agency (FBI, Treasury, etc.)
• Restricted words: "Bank," "Insurance," "University" require additional state approval
• Must be distinguishable: From all existing Wisconsin business names in the DFI database

Every Wisconsin LLC must designate a registered agent with a physical Wisconsin street address who is available during regular business hours to receive legal documents and official state notices.

Who can be your registered agent?

• Yourself: Must have a physical Wisconsin address and be available during business hours
• A trusted individual: Any Wisconsin resident with a physical address
• A professional service: Like Brendat, which keeps your personal address off public records

The Articles of Organization officially creates your Wisconsin LLC. You file with the Wisconsin Department of Financial Institutions online via the DFI portal or by mail.

Wisconsin does not legally require an operating agreement, but it is strongly recommended for all Wisconsin LLCs. It establishes ownership, profit sharing, and management rules, and protects your liability shield.

Your operating agreement should cover:

• Ownership structure: Each member's percentage and capital contribution
• Profit distribution: How and when profits are divided among members
• Management: Who makes decisions and how voting works
• Member changes: Process for adding or removing members
• Dissolution: Steps to wind down the LLC if needed

An EIN is your LLC's federal tax ID, required to open a business bank account, hire employees, and file taxes. You apply through the IRS at no cost.

• US residents: Apply free online at IRS.gov for instant approval
• Non-US residents: Apply by fax using IRS Form SS-4, 4-6 weeks processing
• Brendat handles this: Included in Standard and Premium packages

Wisconsin is one of the few states that does not require LLCs to file an annual report. Once your LLC is formed, there is no ongoing annual report filing requirement.

No annual report fee in Wisconsin
Unlike most states, Wisconsin LLCs are not required to file annual reports or pay ongoing report fees. This makes Wisconsin one of the most affordable states to maintain an LLC long-term.

Note: While there is no annual report, you are still required to keep your registered agent information current with the Wisconsin DFI. If your registered agent changes, you must file a Change of Registered Agent form ($10 fee).
