Iowa picks, best first
The order comes from our five tests: three-year cost first, then what the price covers.
#1Our top pick
1. Mainstay Filing: best for skipping the biennial report
$199 a year, plus the $50 state fee
The biennial report gets filed inside the $199 yearly price, along with formation and the registered agent. That's why Mainstay Filing is first.
Iowa Registered Agent.co saves $200 across three years. The difference buys the extra jobs covered here.
You won't file the biennial report yourself. Iowa still charges $30, billed at cost.

What do the picks cost over three years?
Mainstay Filing will set you back $597, and Iowa Registered Agent.co will set you back $397, and IA Registered Agent.org will set you back $397, services only.
Where do these numbers come from?
State fees come from Iowa's official documents, and service fees come from each company's own price page. Both are dated here.
Do I have to use a service?
No. You can file with the state yourself. A service saves you time and can be your agent, but nothing makes you hire one.
