Our favorite is Iowa Registered Agent.co, because the Iowa formation costs $199 over the state's fee, with the registered agent free the first year, and keeping the agent is $99 a year.
You get a street address in the state for your registered office, and any papers served on the company are scanned into your online account.
The biennial report isn't part of its published price, so you send it to Iowa yourself every two years.
Over three years it costs less than Mainstay Filing, and cost is one of our two biggest criteria.
2. Mainstay Filing: best for formation, agent and biennial report in one simple price
$199 a year, and the state fee goes on top ($249 at checkout)

Coming in second is Mainstay Filing, because the Iowa formation, your registered agent and the biennial report all come in a single $199 price.
When your plan renews, Mainstay files the biennial report for you. Iowa charges $30 every two years for it, and the date is April 1 of odd-numbered years. Mainstay passes the state's fee along at cost.
Iowa Registered Agent.co is $200 cheaper over three years, so Mainstay Filing comes second on cost.

We took each price from the company's own pages on November 12, 2026. On top of every row, Iowa charges a $50 filing fee, which isn't in these totals.
How the order came together
Two things count most to us, three-year cost and filings in the price, at 29% each. Renewal price, state fit and up-front totals share 42%, and Iowa came down to three-year cost.
Iowa Registered Agent.co comes to $397 over three years, which is $200 less than Mainstay Filing. Mainstay would file the biennial report too, but you can do it yourself for the state fee, so the lower price won here.
