Why IA Registered Agent.org is first
Our method scores three-year cost (30%) and what one price covers (30%) most heavily, then renewal terms, fit for the state and price clarity. Here the order came down to three-year cost.
IA Registered Agent.org's three-year total is $397 ($100 below Mainstay Filing). Both include the first agent year, so the renewal price after that decided it.

How foreign registration works in Iowa
Registering costs $100 at the Iowa Secretary of State, Business Services, using the Limited Liability Company Foreign Registration Statement (Form 635_0010). Iowa also wants certificate of existence (good standing) from the state or country of formation, dated within 90 days.
After registering, the company files the biennial report ($30), due January 1 to April 1 of each odd-numbered year.
What to have ready
- Certificate of existence (good standing) from the state or country of formation, issued no more than 90 days before you file.
- Your legal name exactly as registered at home, and the formation date.
- A registered agent in Iowa; each service on this page acts as one.
- The $100 state fee, paid with the filing.
- A date in your calendar for the biennial report and its $30 fee.
The cost of not registering
No lawsuits in state court until the company registers (Iowa Code 489.902). Its contracts stay valid (Iowa Code 489.902(3)).
