Starting an LLC in Idaho is Easy

Most states have made it pretty straightforward to actually apply for an LLC, and we'll show you all of the steps you need to cover in this guide.

If this is your first time applying for an LLC in Idaho then we recommend that you read through the whole guide because it will make your application process much less painful if you understand all of the necessary steps.

Why Should You Apply for an LLC in Idaho?

A Limited Liability Company (LLC) is a very common and popular business structure. It's very useful for you because it offers you liability protection in case of a lawsuit (hence the name limited liability).

What that means is that if your company were to get sued, your personal assets like your home, any vehicles, and your personal bank account would be protected.

You can also use your Idaho LLC to purchase assets like real estate, and keep it separated from your personal assets.

If you are serious about your business venture then applying for an LLC in Idaho is a relatively cheap way to protect yourself personally.

1. Idaho LLC Name

Okay, so the very first step you should always before you apply for an LLC is to check and make sure the business entity name you'd like to use is available for use in your state.

The name of your Idaho LLC needs to be unique and distinguishable from other businesses that have already been registered in the state.

To perform a business name search in Idaho you can use the Business Search page.

If there are companies that you think might be too similar in name to your chosen name in the state database, it's good practice to actually call them to confirm.


Your chosen LLC name needs to have a designator at the end of it. To keep it simple and to comply with Idaho law, we suggest that you pick one of the following:

  • LLC or L.L.C. (LLC is the most common as it is easier to type!)
  • LC or L.C.
  • Limited Liability Company

Important note: your Idaho LLC name CANNOT include a designator that makes it appear to be a different type of business entity. This means you cannot use Inc, Incorporated, LP, LLP, or anything misleading in your name.

To find out more about the designator rules in Idaho, see the form section 30-21-301.

2. Idaho Registered Agent

The Idaho Secretary of State requires all LLC Certificate of Formation filings to have a Registered Agent listed on the form.

A Registered Agent in Idaho is a company or person that you choose (and they agree) to receive all notices, mail, and court documents in the event that your LLC is sued or involved in a court case.

You can do this yourself but if you do so, your address will be publicly listed as the Registered Agent for your company. As you can imagine, that's not very private and can lead to issues.

Generally speaking, we recommend that you use a Registered Agent service. This keeps your personal details private and adds that separation between business and personal communications.

If you choose to apply for an LLC in Idaho by using an LLC formation service like ZenBusiness, IncFile, or Northwest Registered Agent, they will provide you with one year of registered agent service for free.

Idaho LLC Operating Agreement

When you apply for an LLC in Idaho, an Operating Agreement is a written contract that is used to explain who owns the LLC and how much of it they own.

This is important because it sets out how the LLC is managed, how profits are split, taxes paid, and so on, to avoid disputes with the LLC Members.

You will need an Operating Agreement when applying for an LLC in Idaho for both Single-Member LLCs and Multi-Member LLCs.

Apply for an EIN for Your Idaho LLC

Once you have applied for your LLC and been approved, you can then apply for an EIN (Employer Identification Number).

Also known as an FEIN or Federal Employer Identification Number, your Idaho LLC's EIN number is used to identify your LLC to the IRS for tax and filing purposes.

When you open an LLC bank account, you'll need your EIN number to get the account approved.

To apply for an EIN in Idaho you can either apply online here, or file form S3-4 with the IRS by post.
