Every Wisconsin LLC must keep a registered agent and registered office in Wisconsin, filed with the Department of Financial Institutions (DFI) rather than a Secretary of State. The agent can be a Wisconsin resident or a qualifying business entity, but never your own company, and the office must be a real street location. Changing your registered agent costs $10 online or $25 on paper as of October 2026. We recommend Mainstay Filing at $149 a year; WI Registered Agent.org is a lower-cost alternative.

Who can be a registered agent in Wisconsin?
Wisconsin’s LLC chapter was recodified by 2021 Wisconsin Act 258, which adopted the Uniform Limited Liability Company Law, and the current registered agent rules are in section 183.0115. Older guides that cite pre-recodification section numbers are out of date. The agent must be one of the following, with a business office identical to the LLC’s registered office:
- A natural person who resides in Wisconsin
- A domestic corporation, nonstock corporation, LLC, limited partnership or LLP
- A foreign entity of one of those types that is authorized to transact business in Wisconsin
The agent also needs an email address and a place of business or activity in Wisconsin, and it must consent to serve. Both the state’s change form (Form 13) and its LLC formation form (Form 502) state that the entity may not name itself as its own registered agent.
What counts as a registered office The statute requires an actual physical location with a street address. A P.O. box, a mailbox service or a telephone answering service on its own does not qualify. In practice, the registered office is wherever your agent works.
What does a Wisconsin registered agent do?
The registered agent receives service of process, the formal delivery of a lawsuit, along with other legal notices and demands directed at your LLC. The agent then gets those documents to the people who run the company. The agent’s name and registered office address are part of the public record that anyone can look up on DFI’s business search.
Because a court’s response deadline usually begins when papers are delivered, reliability is what you are paying for. A good agent is at the registered office during business hours, logs what arrives, and notifies you promptly, ideally with a scanned copy. The agent has no authority over the business and does not take on its debts or liabilities.
When you compare services, check that the provider has its own Wisconsin street location (not just a mailbox service, which the statute rules out), that it explains how you will receive documents, and that its renewal price matches the first-year price.
Can you be your own registered agent in Wisconsin?
Yes, as an individual. If you live in Wisconsin, you can be named personally as your LLC’s agent, with your business office as the registered office. The LLC itself cannot be named.
Points to consider before you list yourself:
- The registered office address and agent name are public on DFI’s records
- You need to be available at that location to receive legal papers
- Owners living in Illinois, Minnesota, Michigan or Iowa cannot serve personally
- DFI requires an email address for the agent, so notices may come to your inbox as well
How much does it cost to change a registered agent in Wisconsin?
A Statement of Change of Registered Agent and/or Registered Office costs $10 when filed online and $25 on paper, according to DFI’s fee table as of October 2026. The paper version is Form 13, which offers optional expedited service for an extra $100. Form 13 is shared by corporations, LLCs and other entity types.
Filing online is both cheaper and simpler. The same online-versus-paper split applies to other DFI filings: forming an LLC costs $130 online or $170 on paper, and the annual report costs $25 online or $40 on paper. Mainstay’s Wisconsin LLC cost guide pulls these costs together.
How to change your registered agent in Wisconsin
- Choose a qualifying agent and get its consent, along with its Wisconsin street address and email address.
- Go to DFI’s online filing page and select the statement of change for your LLC.
- Enter the new registered agent’s name, the registered office street address and the agent’s email address.
- Pay the $10 online fee and submit. (On paper, use Form 13 and enclose $25.)
- Confirm the update in DFI’s business records search.
Wisconsin annual reports and your agent
Wisconsin LLCs file an annual report each year by the end of the calendar quarter that contains their anniversary date: March 31, June 30, September 30 or December 31. DFI sends a notice ahead of the deadline. The report costs $25 online or $40 on paper, a $25 late fee applies after the deadline, and continued failure to file can lead to administrative dissolution.
The annual report lists the registered agent, so it is a natural checkpoint. If anything has changed, file a statement of change first so the record is accurate.
