1. Mainstay Filing: best for one price that covers the paperwork

$199 a year ($249 due at signup with the state fee)

Mainstay Filing is the one we'd hire first in Iowa, because it forms the LLC, serves as its registered agent and files the biennial report for $199 a year, and the price stays $199 at renewal.

Iowa Registered Agent.co is $200 less over three years, but leaves more filings with you.

It handles each biennial report, adding just the $30 the state charges.

The price covers

  • Formation, done for you
