The reasoning for the order
Two criteria carry 31% each in this ranking, charge over three years and work taken off the founder. Renewal conduct, fit with local rules and pricing in plain sight share 38%, and in Wisconsin the decisive one was work taken off the founder.
Mainstay's plan reaches further: papers served on the company are scanned within the same business day at no cost, the price is identical across all fifty states, and three government letters a year are scanned free. WI Registered Agent.org charges less, so the margin is narrow.
Each criterion and its weight appear on How we rank.
What Wisconsin requires of a registered agent (source: the Department of Financial Institutions (DFI))
Every LLC must name a registered agent with an in-state street address. The address has to be an actual physical location with a street address in Wisconsin, not solely a P.O. box, mailbox service or answering service. Authority: Wis. Stat. § 183.0115.
The Wisconsin annual report: its fee and due date
In Wisconsin, the annual report comes due every year. $25 is payable to the state, and the deadline is end of the calendar quarter containing the LLC's anniversary date. Filing late adds $25. Notices about it are sent to your registered agent.
