Prices were read from each company's own pages on November 12, 2026. Wisconsin's fees do not depend on which agent you choose.

How the order was set

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 total over three years.

Wisconsin Registered Agent.co totals $297 over three years, $150 under Mainstay Filing. A company that needs an agent in Wisconsin only gains little from fifty-state coverage, so the lower yearly price decided it.

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