The short answers
What does the state charge?
$50, paid once
Every year after
$30 once every two years
Registered agent
Yes, the law says so
Who to ask
Mainstay Filing, IA Registered Agent.org then Iowa Registered Agent.co
1. Mainstay Filing: best for one price for setup and upkeep
Annual price $199, renewal price $199, state fee on top
Why Mainstay Filing at the top? One yearly price of $199 pays for forming the LLC, serving as the registered agent and filing the biennial report, then renews at $199.
Over three years this costs $200 more than IA Registered Agent.org, and you hand off more filings in return.
Because the biennial report is inside the service, the only extra is Iowa's own $30, billed at cost.
How was the bottom line figured? Add the filing fee, the next two reports and the minimum tax if the state has one. Anything with no fixed price, a newspaper notice for instance, is described above and kept out of the sum.
Still wondering?
Is the EIN application included?
Mainstay Filing includes the EIN application. The others charge extra: IA Registered Agent.org $99; Iowa Registered Agent.co $99.
What do the picks cost over three years?
Mainstay Filing comes to $597; IA Registered Agent.org comes to $397; Iowa Registered Agent.co comes to $397 for the services alone.
Are the fees official?
Each state fee links to its official page, and each service price is read from the company's own site.
Do I have to use a service?
Hiring help is a convenience you pay for, never a legal duty.
Are there yearly state fees?
One filing keeps coming back: the biennial report, on a two-year cycle, for $30. The state says it is due April 1 of odd-numbered years.
Which one do you recommend in Iowa?
Mainstay Filing comes first: $199 a year includes the formation, the registered agent and every biennial report. Next are IA Registered Agent.org and Iowa Registered Agent.co.
