Step 1: Name your Idaho LLC
When starting your business in Idaho, you must pick a name first. There are a few essential requirements to keep in mind:
- Your business name contains “limited liability company,” “LLC,” or “L.L.C.”
- It must be unique and not already used by another business in Idaho. You can check the Secretary of State’s website for name availability.
- Avoid using words that imply your business is a government agency (e.g., State Department, CIA, FBI, Treasury).
- Some words, such as “bank,” “lawyer,” “attorney,” “credit union,” etc., may require additional paperwork or licensing. Idaho’s official website has a complete list of business naming rules.
Additional considerations:
Reserve your name: In Idaho, you can reserve names for up to 120 days by paying the fee and submitting the appropriate form to the state authority. You can reserve a name by submitting a Reservation of Legal Entity Name with the Secretary of State, which can be done online or by postal mail, with a filing fee of $20 ($40 for mail filings).
Website domain: Even if you’re planning to wait before creating a webpage, securing your domain name is a good idea now. Before settling on your LLC name, check if your desired URL is available and suitable.
Step 2: Choose a Registered Agent
To start an LLC in Idaho, you must have a designated agent for the service of process within the state. This individual or business entity accepts legal documents on behalf of the LLC if it faces a lawsuit. Here are the criteria for the registered agent:

- The agent must be a registered entity or company offering registered agent services.
- They must have a physical address in Idaho.
- The agent must be available to accept legal documents in person during regular business operations. A list of registered agents is available online.
Step 3: File an Articles of Organization
To set up an LLC in Idaho, you must submit a Certificate of Organization of a Limited Liability Company to the Idaho Secretary of State. You can do this online or by mail. The filing cost is $100, or $120 for mail submissions, payable by credit card.
Your Certificate of Organization should include:
- LLC name
- The principal address of the LLC
- Name, address, and signature of the agent
- Name and address of a “governor,” who can be a manager or member depending on the business management structure
- Date of LLC formation
- Signatures of the organizers
If you have a foreign LLC (from another state) and want to do business in Idaho, you must complete a Foreign Registration Statement, which costs $100 to file and $20 to process.
Step 4: Received a Certificate From the State
After the LLC’s formation documents are submitted and authorized, the state will issue a certificate verifying the LLC’s establishment. This certificate allows the LLC to obtain an Employer Identification Number and business licenses and open a bank account.
Step 5: Create an Operating Agreement
Although not required by law, creating a thorough LLC operating agreement is strongly advised for all new limited liability companies when you start an LLC in Idaho.
This agreement should:
- Describe the business structure of the LLC.
- Define the responsibilities and duties of LLC members.
- Outline how the business will operate.
With such an agreement, the LLC might avoid legal and operational issues.
Step 6: Get an Employer Identification Number
The Internal Revenue Service will assign you a nine-digit Employer Identification Number (EIN) to identify your LLC for tax purposes. You can obtain your EIN through the IRS either by mail or online.

An EIN helps with:
- Filing and managing taxes at state and federal levels.
- Opening a bank account.
- Hiring employees.
The IRS website allows you to get an EIN for free. Once you submit the form, you’ll receive your number immediately.
