Who we would hire in Iowa

What counts most: three-year cost and how many assignments the price finishes. How we grade lists all five criteria.

Top of the class

1. Mainstay Filing: best for new owners who would rather hand off the work

Start with this one$199 per year, with $249 at checkout to cover the state fee

Our first pick is Mainstay Filing; $199 a year hands over three assignments at once: the filing, the registered agent and the biennial report.

You pay $200 more over three years than at Iowa Registered Agent.co and leave less of the paperwork to yourself.

You never file the biennial report yourself, and only the $30 state fee is added.

What the price covers

  • We mean: the filing is done for you
  • Registered agent for the whole year
  • Biennial report filed for you on time
  • The EIN application is part of the price
  • The official fee, nothing added

What works

  • $199 when you renew
  • A single $199 yearly price, biennial report included
  • It files your EIN application for you

What to weigh

  • $100 a year more than Iowa Registered Agent.co at renewal

2. Iowa Registered Agent.co: best for a cheap Iowa start

In-state service$199 plus the state fee, then $99 a year

Pick number 2 is Iowa Registered Agent.co, where $199 gets you started and the agent costs nothing in year one; from year two it is $99.

The price leaves out the biennial report, so that is yours to file every two years.

What the price covers

  • The formation filing
  • A year of agent service is part of the price

What works

  • Then $99 per year
  • $199 to form
  • Agent covered in year one

What to weigh

  • It does not file the biennial report for you
  • The EIN application is not included ($99)

In-state service$199 plus the state fee, then $99 a year

Pick number 3 is IA Registered Agent.org, where $199 gets you started and the agent costs nothing in year one; from year two it is $99.

How a Iowa LLC gets formed

  1. Task 1

    Make sure nobody else has the name

    Your first assignment is a name search with the Iowa Secretary of State, so you do not file under something a neighbor already uses.

    Keep a second choice in your pocket.

  2. Task 2

    Settle who your registered agent will be

    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.

    This role comes with each recommended service.

  3. Task 3

    Self-filing versus a service

    Skip the services and you pay the state $50. Use one of our picks and you pay $199 extra to skip the forms.

  4. Task 4

    File the Certificate of Organization

    Once the Iowa Secretary of State accepts the Certificate of Organization and $50, the LLC exists, as Iowa Code § 489.201 provides.

  5. Task 5

    Apply to the IRS for an EIN

    The IRS hands out EINs, not Iowa. Apply once the state approves you, then give the number to your bank. If you hire Mainstay Filing, the EIN application is taken care of.

  6. Task 6

    Prepare the operating agreement

    Ownership and decision rules live in the operating agreement, an internal paper that is no part of the Iowa filing.

  7. Task 7

    Handle Iowa's recurring filing

    To stay active, send the biennial report every two years ($30) by April 1 of odd-numbered years.

Biennial reportState agency$30 every two years

The reasoning behind the order

Assignments the price completes makes up 31% of the grade, and that is where got ahead in Iowa.

Iowa wants the biennial report every two years, so a price that files it beat a lower price that leaves it to you.

Questions students ask

Which fees does Iowa collect when an LLC is formed?

The fee on the official schedule is $50. Put $199 on top if a service does the filing.

Which form creates the LLC?

The Certificate of Organization, which you send to the Iowa Secretary of State.

Is a registered agent required?

Every LLC must name a registered agent with an in-state street address.

What does Iowa require each year?

Calendar note on the biennial report: $30, filed every two years, timing as the state words it: April 1 of odd-numbered years.

Can I form the LLC without a service?

Nothing stops you: the state asks $50, and you also have to name a registered agent.

Which LLC service should a first-time founder use?

The order is Mainstay Filing, Iowa Registered Agent.co and IA Registered Agent.org, and Mainstay Filing is first since the yearly $199 replaces three separate bills (formation, registered agent, biennial report) with a single one.
