Follow our How to Start an LLC in Idaho guide below to get started.

Steps to form an L L C in Idaho

Step 1: Create A Name For Your Idaho LLC

Before you register your LLC, you'll need to come up with a name. Your business name needs to be catchy for branding purposes and legitimate for legal purposes.

We go into depth on this topic in our LLC naming guide. We’ll go over the basics below.

Naming Your LLC

First, brainstorm some possibilities. Use our LLC name generator to get the ideas flowing.

Next, make sure your name meets Idaho guidelines:

  • it contains the words limited liability company, limited company, LLC, or L.L.C.
  • it doesn't contain restricted words or phrases (these often include words like bank, attorney, and university) without approval
  • it's distinguishable from any other entity or trade name registered in Idaho
  • full list of Idaho naming guidelines

Next, do an Idaho LLC name search with the Secretary of State to find out if your name is available in Idaho.

If your business name is available and meets guidelines, you’ll be able to register it when you file your Certificate of Organization with the Secretary of State.

Is the URL available? Before you commit 100% to a name, check to see if there’s a good web domain available.

We recommend buying your domain right away because even if launching a business website isn’t on your radar right now, it will be soon.

Once you register a domain name for your LLC, consider setting up a business phone system to establish credibility and enhance your customer service. Nextiva provides a plethora of useful features and a quick, easy setup. Try Nextiva.

Step 2: Appoint An Idaho LLC Registered Agent

When you file your Certificate of Organization, you'll need to list a registered agent.

A registered agent's job is to accept legal documents like service of process and tax notices for your LLC.

Your registered agent can be a person or a registered agent service. You can act as your own registered agent, but many business owners choose to use a registered agent service.

Here are a few things to think about before you decide to act as your own registered agent:

  • You’ll need to be available during normal (9 am - 5 pm) business hours at the address you provide
  • If you run your business from home, you’ll have to make your personal address public
  • You could be served with a lawsuit in front of your family or coworkers

Recommended: Most registered agent services offer a year of registered agent service free when you form an LLC with them. 

Step 3: File A Certificate of Organization

It’s time to officially form your LLC by filing your Certificate of Organization with the Idaho Secretary of State.

You can file online with the Secretary of State or fill out a hard copy of the Idaho Certificate of Organization and mail it in or deliver it in person. The filing fee is $100 online or $120 by mail or in person. 

Recommended: Now is a good time to decide if your LLC will be member-managed vs manager-managed.

You'll need to know the following information to complete the form:

  1. Entity Name and Address
  2. Registered Agent Name and Registered Office Address
  3. Name and Address of at least one LLC governor

For more detailed help with completing the form, visit our Idaho Certificate of Organization guide.

Mail Your Certificate of Organization:

Send the form and payment (payable to the Secretary of State) to:

Office of the Secretary of State
450 N 4th Street
P.O. Box 83720
Boise ID 83720-0080

Submit In Person: 
Office of the Secretary of State
450 N 4th Street
Boise ID 83720-0080

How long does it take to get an LLC approved? LLC processing time is 7 to 10 days but may be expedited for an additional fee.

Step 4: Create An Idaho LLC Operating Agreement

Creating an Idaho LLC operating agreement is the only way to legally lock down your LLC’s management and ownership structure. Having this document in place will give you something to return to if a dispute or lawsuit arises. 

Even single-member LLCs benefit from having an operating agreement.

Your operating agreement should outline the following:

  • Each member’s responsibilities
  • How new members will be admitted
  • How existing members may transfer or terminate their membership
  • How profits and dividends will be distributed

You can add as many provisions as you want, as long as they don't conflict with Idaho business law. Take a look at our What is an Operating Agreement guide to learn more.

Step 5: Get an EIN

The Employer Identification Number (EIN), Federal Employer Identification Number (FEIN), or Federal Tax Identification Number (FTIN), is essentially a Social Security number (SSN) for your company. State and federal agencies use this number to track your business activity.

Your EIN will come in handy when it’s time to:

  • Open a business bank account
  • File Federal and State taxes
  • Hire employees

We think the best way to get an EIN for your Idaho LLC is by using the free online application on the IRS website. We prefer this method because it's the most efficient, but you can apply by phone, fax, or mail. You can read through our How to Get an EIN guide to find out how.
