Year one of the registered agent is on the house; every renewal after that is $149.

The questions that matter
When does an out-of-state LLC have to register?
Before your LLC does business in Iowa. You register with the Iowa Secretary of State, Business Services, then you start working.
If you skip it, expect Iowa's courts won't hear its claims (Iowa Code 489.902).

How much does registering run?
The state charges $100, and a service adds $199.
Over three years the state's fees reach $130, counting any recurring report. sos.iowa.gov, confirmed October 2026, if you don't believe us
Which form, and who gets it?
Once the Iowa Secretary of State, Business Services accepts the Limited Liability Company Foreign Registration Statement (Form 635_0010), your LLC is registered.
Attach certificate of existence (good standing) from the state or country of formation issued within the last 90 days.
Is there a filing that repeats?
The state wants a biennial report later, and it's $30.
Per the state, it's due January 1 to April 1 of each odd-numbered year.
What put number one on top?
On jobs the price actually covers (30% of the score), Mainstay Filing wins.
Two tests carry most of the weight: money out the door in three years (35%) and jobs the price actually covers (30%).
An out-of-state LLC already works in two states, and the first pick can cover both.

The rows above, added up
The last row is our math, not the state's: filing fee, plus the reports in years two and three, plus any minimum tax. If a cost has no fixed amount, like a newspaper notice, it's explained above and left out.
Still wondering?
Do I still need an agent at home?
Yes. Your home state has its own agent rule, and Mainstay Filing can cover both states from one account.
What do the picks cost over three years?
Over three years you're looking at $497 at Mainstay Filing, $397 at IA Registered Agent.org, $397 at Iowa Registered Agent.co, before state fees.
Where do these numbers come from?
Official Iowa sources back the state side, and posted prices back the service side.
Do I have to use a service?
No. You can file with the state yourself. A service saves you time and can be your agent, but nothing makes you hire one.
Will a service file it for me?
Each company on this page files it for you.
Who should I use for a foreign registration service in Iowa?
Mainstay Filing is first: it's $199 to register, with a free first registered agent year and $149 a year from then on. Then comes IA Registered Agent.org and Iowa Registered Agent.co.
