A Registered Agent is a person or company that accepts legal mail and state notices on behalf of your LLC. Wisconsin requires your Registered Agent to have a physical street address in the state — PO Boxes are not allowed. Your options:
- Yourself (if you have a physical address in Wisconsin)
- A friend or family member who lives in Wisconsin
- A professional Registered Agent service

Step 4: Create an Operating Agreement
An Operating Agreement is an internal document that shows who owns the LLC and how it will be run. You do not need to file it with the state or the IRS — just keep it with your business records. All LLCs should have one, even single-member LLCs.
Step 5: Get an EIN from the IRS
An EIN (Employer Identification Number) is your LLC's federal tax ID. It is free from the IRS and is needed to open a business bank account, hire employees, and file taxes.
- US residents with an SSN: Apply online at IRS.gov (takes ~15 minutes, free)
- Non-US residents without an SSN: Apply by fax or mail using Form SS-4 (takes 1–3 months)
Step 6: File Your Annual Report
First due: By the end of the quarter including your anniversary date in the year after formation
After Your LLC Is Approved
Open a business bank account
Keep business and personal finances separate to maintain liability protection. You will need your EIN and your stamped/approved Articles of Organization to open an account.
Get business licenses and permits
Wisconsin does not have a state general business license. Depending on your business type, you may need a professional license or permit from a state agency.
Understand your tax obligations
LLCs don't pay federal income tax directly. Profits and losses pass through to the members, who report them on their personal federal tax returns.
Wisconsin has a state income tax. LLC members report their share of profits on their Wisconsin state tax return.
