1. Mainstay Filing: best for formation, agent and annual report for one price

$199 each year plus the state fee ($329 due at checkout)

9.4Editorial score
out of 10

Mainstay Filing wins here: $199 a year pays for the formation filing, a full year as your registered agent and the annual report, renewing at $199.

Mainstay files the annual report for you as part of the renewal. Wisconsin charges $25 every year, due end of the calendar quarter containing the LLC's anniversary date, and a late filing adds $25; the state's fee is passed through at cost.

The three-year bill is $200 higher than WI Registered Agent.org's, and the wider coverage is worth that to us.

Prices were read from each company's own pages on November 12, 2026. Wisconsin's $130 filing fee goes on top of every row and is not counted in these totals.

Why Mainstay Filing comes first

Two criteria lead Filing Verdict's method at 35% apiece: total over three years and paperwork the price handles. Renewal behavior, match to the state and up-front pricing share the other 30%, and Wisconsin came down to paperwork the price handles.

Wisconsin wants a report every year with a $25 state fee, and filing late adds $25. Mainstay's price includes that filing and WI Registered Agent.org's does not, so the coverage score outweighed WI Registered Agent.org's lower three-year cost.

The full list of criteria and weights is on How we rank.
