Our Iowa picks

The order comes from our five checks: three-year cost first, then how much the price covers.
Start here

1. Mainstay Filing: best for not having to think about the biennial report

$199 a year, with the $50 state fee added

Number one is Mainstay Filing, since you pay $199 a year and the formation, the registered agent and the biennial report get done.

Across three years it costs $200 more than IA Registered Agent.org, and you hand off more of the filing in return.

The biennial report is part of the service, with only the state's $30 added.

Your money buys

  • LLC formation handled for you
  • Registered agent year-round
  • Biennial report taken off your plate
  • EIN application
  • The state's fee at cost

The good

  • The EIN application is part of the deal
  • A single yearly price of $199
  • No surprise at renewal: $199

Trade-offs

  • After year one it costs $100 more a year

2. IA Registered Agent.org: best for a small first-year bill

$199 up front, then $99 a year, plus the state fee

IA Registered Agent.org comes next since forming your LLC costs $199 and the agent is covered in year one, then $99 a year.

The biennial report isn't part of the price, so that's on you.
