How we picked the order
The Founders Review weighs five things, led by three-year cost and what one price covers at 30% each. For Iowa, what one price covers is what separated first place from second.
Mainstay Filing's plan covers more per dollar on our coverage criterion: same-day scanning of legal papers at no fee, three free mailing scans a year and one price in all fifty states. IA Registered Agent.org wins on cost, and its score sits close behind.
