Still wondering?
Do I still need an agent in my home state?
Expect to name one in each state. Mainstay Filing is active in all fifty, so it can serve the pair together.
What do the picks cost over three years?
Mainstay Filing comes to $497; Iowa Registered Agent.co comes to $397; IA Registered Agent.org comes to $397, before state fees.
Where do these numbers come from?
State fees come from Iowa's official documents, and service fees come from each company's own pricing page. Both carry dates on this page.
Do I have to use a service?
Hiring help is a convenience you pay for, never a legal duty.
Can I hire someone to register the LLC?
Yes, filing is part of what each company on this page sells, and the state's fee is identical whoever sends it.
Who should I ask first about a foreign registration service in Iowa?
Mainstay Filing comes first: registering costs $199 and the registered agent is free until year two. Next are Iowa Registered Agent.co and IA Registered Agent.org.
