1. WI Registered Agent.org: best for a Wisconsin LLC that wants to stay close to home

$199 to form, then $99 a year for the agent, plus the state fee

Our mark 9.4 out of 10

Top grade, WI Registered Agent.org: it forms the LLC in Wisconsin for $199 over the state's fee, with the registered agent free for year one, and keeps the agent for $99 a year.

You get an in-state street address for the registered office, and any papers served on the company are scanned into your online account.

Three years of its fees come to less than Mainstay Filing charges.

Formation, agent and report

2. Mainstay Filing: best for formation, agent and annual report wrapped into one price

$199 yearly, state fee billed on top ($329 at checkout in all)

Our mark 9.2 out of 10

Next up is Mainstay Filing: one $199 yearly price filing the Wisconsin formation, serving as your registered agent and filing the annual report, then renewing at $199.

When renewal comes, Mainstay prepares and files the annual report so it is off your list. The Wisconsin fee is $25 every year, with a end of the calendar quarter containing the LLC's anniversary date deadline, and being late adds $25; Mainstay passes the fee along at cost.

WI Registered Agent.org is $200 lower across three years, which puts Mainstay Filing behind it on cost.

In the price

  • The formation filing, done for you
  • Registered agent duty for the whole year
  • Annual report, prepared and filed each cycle
  • Your EIN application, done for you

Pros

  • Wisconsin's fee goes through at cost
  • Renews at $199 without add-ons
  • A single $199 yearly price that covers the annual report
  • Your EIN application is included

Less good

  • After year one the agent portion is $100 a year above WI Registered Agent.org's
