Explanations
Does the law insist on a registered agent?
Every LLC must name a registered agent with an in-state street address.
Statute: Wis. Stat. § 183.0115. docs.legis.wisconsin.gov, confirmed October 2026
Who can serve in the role?
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.
If you meet the rule, you may name yourself and avoid paying an agent.
What will an agent cost each year?
The recommended services charge $99 to $149 annually, or $297 to $447 across three years.
The state fees are the same whoever you name.
Why does the state require one?
It serves as the LLC's address in Wisconsin for court papers and state letters.
That is the reason the address has to be staffed during business hours. What does service of process mean?
What else comes due each year?
Keep up with the annual report each year ($25). According to the state, it is due end of the calendar quarter containing the LLC's anniversary date, which is easy to miss.
