Key Takeaways

  • An Iowa LLC search helps verify name availability, business standing, and registered agent details before filing formation documents.
  • To form an Iowa LLC, you must file a Certificate of Organization with the Secretary of State and appoint a registered agent with an Iowa address.
  • The business name must include “LLC” or “L.L.C.”, be distinguishable from other entities, and comply with restricted word rules.
  • Iowa allows online or mailed filings, with an electronic option through the Fast Track Filing system.
  • After formation, LLCs must file a Biennial Report, obtain an EIN, and comply with tax and licensing requirements.

The Iowa LLC Search is the first step in forming an LLC in Iowa. You need to make sure that your desired LLC name is available. This can be done by a quick search at the Iowa Secretary of State web page, whether you're trying to choose a name or want to check an existing business entity's status. Searches are usually done to find whether or not it has been legally formed, the business address, their registered agent's address, and if the business is in good standing.

Here's how to search for your desired LLC name:

  1. Go to the Iowa Business Entities Search page at http://sos.iowa.gov/search/business/search.aspx.
  2. In the “Business Name” search box, enter the name you want for your LLC. Do not include “LLC” or any punctuation. Capitalization is not important.
  3. For a more thorough search, try searching with just the first couple of words in your LLC name. This will turn up anything that is similar.
  4. Click “Search” and a list of existing Iowa businesses should appear.
  5. If you get “no results” then you're in luck; the name you have chosen is available.
  6. If the name you chose shows up, then it is not available and you will need to use your creativity to come up with something else.
  7. If you're not sure if your name is available exactly as you want, you can still file your state paperwork. If the name needs to be changed they will send it back to you.

Name Requirements for LLCs in Iowa

Before you submit your LLC's paperwork with the state, you need to understand some requirements for businesses formed in the state of Iowa:

  • You must use LLC or L.L.C. at the end of your business name. LLC is most common.
  • If you are registering as an LLC, you are not allowed to use the word “Corporation,” “Incorporated,” or their abbreviations.
  • The name of your business must be different from other companies in Iowa. Just switching around grammar, using singular, plural, or possessive forms of the name, etc. are not enough to make the name distinguishable within the state.

Choosing a Good LLC Name

Before you settle on a name, you'll want to do some research. Make sure your name is appropriate for the business you're going to run and is easy to find by potential customers. There are certain words that are restricted for use, such as “bank,” or “attorney,” or anything that would confuse your company with a medical practice, federal or state agency, or other established institution.

You should also check to see if the name you want is available as a web domain name, even if you don't want to create a website. You may wish to do so in the future, or buy the domain name so nobody else can use it.

Once you have chosen your name and made sure it is available for you to use, you will want to reserve it. Your LLC name may be reserved for up to 120 days if you file an application with the Secretary of State called “Application for Reservation of Name.” You may do this by mail or online, and it costs $10.

Reserving and Protecting Your Iowa LLC Name

If you’ve found an available name through the Iowa business entity search, you can reserve it before filing. Iowa allows name reservation for 120 days by submitting an Application for Reservation of Name and paying a $10 fee to the Secretary of State.

You may also protect your business identity by:

  • Registering a trademark with the U.S. Patent and Trademark Office or the Iowa Secretary of State.
  • Registering a DBA (Doing Business As) name if your LLC will operate under a name different from the legal entity name.
  • Checking for domain name availability to maintain brand consistency online.

Choosing Your LLC's Registered Agent

The next step after you have settled on a name is to choose a registered agent. This can be a person or a business, and they must agree to receive legal papers on behalf of your LLC and send them when necessary as well. This includes regular state filings, legal actions, or any other official administrative communications. This person must be an Iowa resident, or a corporation that is authorized to do business in the state. Someone in the company may serve this purpose, including yourself.

Changing or Updating a Registered Agent in Iowa

If you need to change your Iowa LLC registered agent, you can do so at any time by filing a Statement of Change of Registered Office or Agent. This can be submitted through the Fast Track Filing system or by mail with a $5 fee.

The new registered agent must consent in writing to serve. Failing to maintain an active agent can lead to administrative dissolution or missed legal notices.

Your registered agent’s address must always be a physical street address in Iowa, not a P.O. box.

The Certificate of Organization

To finish the official registration process, a Certificate of Organization needs to be filed with the state. This is not a form, but a written statement. Instructions for writing it can be found on the State of Iowa website. It must contain the name of the LLC, its main office address, and the address and name of the registered agent. The cost for this is $50.

Iowa LLC Taxation Overview

Iowa LLCs benefit from flexible tax classification under federal and state law.

  • Single-member LLCs are taxed as disregarded entities, reporting income on the owner’s personal return.
  • Multi-member LLCs default to partnership taxation, filing IRS Form 1065.
  • LLCs may elect to be taxed as an S corporation or C corporation by filing IRS Form 2553 or Form 8832, respectively.

Iowa imposes a state income tax on members based on their share of the LLC’s profits. Depending on the nature of your business, you may also owe:

  • Sales tax on taxable goods or services.
  • Employer withholding tax if you have employees.
  • Unemployment insurance contributions for covered workers.

Filing an Iowa LLC Online or by Mail

Iowa LLCs can be formed by filing a Certificate of Organization either online through the Fast Track Filing system or by mail. The Iowa Secretary of State recommends using the online portal, as it allows same-day processing and instant confirmation of filing.

Online filing requires you to:

  1. Visit the Iowa Fast Track Filing portal.
  2. Create an account and choose “Form a Business.”
  3. Upload your Certificate of Organization document (there is no pre-filled form).
  4. Pay the $50 filing fee electronically by credit card or eCheck.

If filing by mail, prepare a signed written Certificate of Organization that meets Iowa Code §489.201 requirements and mail it with a $50 check payable to the Iowa Secretary of State at:

Secretary of State, Business Services DivisionLucas Building, 1st Floor, Des Moines, IA 50319

Online submissions are processed almost immediately, while mailed filings can take up to two weeks.

Iowa LLC Operating Agreement

While not required by Iowa law, creating an LLC operating agreement is strongly recommended. This internal document defines ownership percentages, profit distribution, and decision-making authority. It also clarifies what happens if a member leaves or the LLC dissolves.

An Iowa LLC operating agreement should include:

  • Member names and ownership shares.
  • Management structure (member-managed or manager-managed).
  • Capital contributions and profit-sharing terms.
  • Voting rights and procedures.
  • Rules for adding or removing members.

Having a signed agreement provides legal protection and strengthens the LLC’s limited liability status, especially in disputes or audits.

Iowa LLC Biennial Report and Ongoing Compliance

After your Iowa LLC is approved, ongoing compliance ensures your company remains in good standing. The state requires a Biennial Report every odd-numbered year to update ownership and contact details.

  • Filing fee: $30 online or $45 by mail.
  • Due date: Between January 1 and April 1 of every odd year.
  • Where to file: Through the Fast Track Filing portal or by mail.

Failure to file on time may result in administrative dissolution. To reinstate, the LLC must pay all past-due fees and file the missing report.

Additionally, LLCs may need:

  • A state business license depending on industry.
  • Local permits for zoning, health, or sales tax collection.
  • An EIN (Employer Identification Number) from the IRS for banking and tax purposes.
