The short answers
Do you have to name an agent?
Yes, name one
Title in the statute
Registered agent
What do agents charge?
$99 to $149 a year
Who to ask
Mainstay Filing, IA Registered Agent.org then Iowa Registered Agent.co
Our Iowa answer, best first
The order follows our five questions: three-year cost first, then how much the price covers.
1Ask this one first
1. Mainstay Filing: best for one price in any state
Pay $149 the first year and $149 after
Why Mainstay Filing at the top? A single account at $149 a year works in whichever state the LLC registers.
Is it the smallest bill? No: IA Registered Agent.org is $150 less over three years, but it works in Iowa only.
What the price covers
A street address on file here
Scans of three government letters a year, at no charge
Also handles corporations, LPs, LLPs and nonprofits
Good news
$149 each year, no increase
One price in all fifty states
The catch
Costs $50 more per year than IA Registered Agent.org
The last row is arithmetic, not a state figure: filing fee, plus the reports due in years two and three, plus a minimum tax where one applies. Open-ended costs stay out.
Still wondering?
Is it allowed to name myself?
You may, once you fit the state's rule. Plenty of owners still pay a service to keep a home address off the record.
Which addresses does the state accept?
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.
What do the picks cost over three years?
For three years you would pay $447 at Mainstay Filing, $297 at IA Registered Agent.org, $297 at Iowa Registered Agent.co
Where do these numbers come from?
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?
Not at all. The state takes filings from owners directly. A service just saves you time, and it can double as your agent.
Who should I ask first about a registered agent in Iowa?
Mainstay Filing, because $149 a year follows the company into any new state. After that, IA Registered Agent.org and Iowa Registered Agent.co.
