Cost over three years first, then to-dos cleared, renewal, Iowa fit and readable pricing (scoring page).
First choice$199 yearly; renewal $199
1. Mainstay Filing: best for dropping the biennial report paperwork
Mainstay Filing gets the top mark in Iowa: the founder pays $199 a year and skips three separate vendors for filing, registered agent and biennial report.
The three-year premium over Iowa Registered Agent.co is $200; the 38% weight on to-dos cleared outweighs it.
The biennial report is on its to-do list, and Iowa's $30 fee is billed to you at cost.

The primer, move by move
Move 1
Name the company
Name search comes first. Use the records at the Iowa Secretary of State.
Keep a runner-up name in reserve.
Move 2
Fill the registered agent seat
Every LLC must name a registered agent with an in-state street address. Any individual or business with a place of business in Iowa that has agreed to serve.
The address has to be a place of business in Iowa. The registered office street address and the agent's business office have to match, and P.O. boxes are not accepted.
Any service we rank here can serve as your registered agent.
Where this comes from: Per legis.iowa.gov, as of October 2026
Move 3
Self-file against a service
DIY costs the $50 state fee and your time. A service adds $199 and does the forms; our ranking says which.
Move 4
Fill in and send the Certificate of Organization
The Certificate of Organization is the document that forms the company. Deliver it to the Iowa Secretary of State; the fee is $50 (Iowa Code § 489.201).
Where this comes from: Per legis.iowa.gov, as of October 2026
Move 5
Order the LLC's federal tax ID
After approval, the IRS can give the LLC a federal tax ID, and the business bank account hinges on it. The Mainstay Filing package already includes this move.
Move 6
Write an operating agreement
The operating agreement is the owners' rulebook. The company keeps it; the state does not ask for it.
Move 7
Plan for year two
Iowa requires the biennial report every two years, due April 1 of odd-numbered years, costing $30.
State amounts are Iowa's official fees (sources below); service prices come from each company's site. Three years of state cost is the filing, the reports in years two and three and any minimum tax.
The logic behind the order
To-dos the price takes off you is 38% of the mark, and it is where moved ahead in Iowa.
A price that takes care of the biennial report outweighed Iowa Registered Agent.co's smaller three-year cost.
