We've laid out all the steps you'll need to take to form a legally recognized LLC in Idaho, in chronological order.

An LLC is a type of business that helps protect its owners (called members). This means that if the business owes money or gets sued, the members' personal assets, like their house or car, are usually safe. 

In the state of Idaho, an LLC is defined as having “some of the characteristics of a sole proprietorship, some of a partnership, and some of a corporation.”

If that sounds like a lot of legal jargon - that's because it is! What you need to know is that LLCs are popular with business owners because they are simple and flexible to run. They have fewer rules compared to comportations and the owners can choose if they want to manage the business themselves or appoint managers to do it. 

Another benefit is how taxes work: LLC owners can pay taxes through their own personal tax returns, or they can choose to have the business pay taxes separately, like a corporation. This gives owners more choices in how they handle taxes as their business grows.

Why should I register for an LLC in Idaho?

You may want to register for an LLC in Idaho when:

  • You own or want to start a business in Idaho, or want to expand an existing business into Idaho, and want to stay legally compliant. 
  • You own or want to start a business, and want more flexibility on how you will manage the business or pay taxes than a corporation would provide.
  • You want to protect your personal assets from potential liability resulting from business you conduct in the state of Idaho. 
  • You own or want to start a business, and want to register in Idaho to open accounts, lease or buy property, secure funding, or hire employees.

Do I need to file my LLC in Idaho if I live in another state?

Any LLC that does business in Idaho must file with the State of Idaho. LLCs based in Idaho are called "domestic LLCs," and out-of-state LLCs are called "foreign LLCs." If your LLC was organized and operates outside of Idaho, establishing a foreign LLC within Idaho will allow for you to conduct business there.

Foreign LLCs and domestic LLCs may have different filing and compliance requirements -- Rocket Lawyer can help you navigate foreign LLC registration, regardless of where you live.

How to start an LLC in Idaho

1. Find a unique name for your Idaho LLC

The state of Idaho requires that the names of all LLCs in the state:

  • They must include the term "LLC" or "Limited Liability Company," also known as an "entity designator." 
  • "L.L.C." and the abbreviations "Ltd." and "Co." are acceptable.
  • If the limited liability company is a professional entity, the name may include the word "professional" before the word "limited" or the letter "P" at the beginning of any of the permitted abbreviations.
  • They must not be too similar to existing LLCs in the state.

Rocket Lawyer can help you determine whether your business' name is eligible for registration in Idaho and may be able to help you reserve the name before you file your LLC.

2. Include your other LLC members (if any)

In Idaho, you can in fact form as a one-person LLC.In this case, the LLC would be referred to as a single-member LLC (SMLLC), whereas if there is more than one owner, the LLC may be called a multi-member LLC. 

The main difference between single-member and multi-member LLCs lies in ownership structure and management. With a single-member LLC, you have full control over the business. In contrast, a multi-member LLC has multiple owners, each with a specific percentage of ownership as defined in the operating agreement. This means that in a multi-member LLC, owners share profits, losses, and tax responsibilities based on their ownership percentage.

3. Provide an Idaho address

This will be used as your official LLC address. The address that you list may either be your home, an office, or another physical location, but it cannot be a PO box.

4. Choose a Registered Agent

A Registered Agent is the person or business responsible for receiving tax, legal, and government documents during regular business hours. It's important that every business has one. You can either serve as your own registered agent (if you have an Idaho address) or choose one to do that service for you (if you are not located in Idaho or would like an extra layer of privacy).

5. Register your LLC with the state of Idaho

Once you have a business name and registered agent, you can register your business as an Idaho LLC with the state of Idaho by filing your Certificate of Organization. In other states, this document may be called a "Certificate of Formation," "Certificate of Filing," or "Articles of Organization."

6. Get an Employer Identification Number (EIN)

Idaho LLCs are required to have a Federal EIN tax number. Think of your tax ID as the social security number for your company. It will be important for business contracts, tax filings, and all manner of documents down the line. Every company should have one to remain in good standing.

7. Pay the state filing fee

Every state has different fees for forming an LLC, which can also vary from one year to another.

Congratulations! After you have completed all these steps, you have formed your Idaho LLC.

What to do after forming an Idaho LLC

There are a few steps you need to take to maintain your Idaho LLC:

  1. Create an Operating Agreement: while not mandatory, this is very advisable. We can help you create your Idaho LLC Operating Agreement online.
  2. Hold a meeting: a first meeting with members of an LLC is not required by law, but it is highly suggested in order to get organized. Also, unlike corporations, LLCs are also not required to maintain Meeting Minutes, but these documents are also recommended as they provide records for important decisions made.
  3. Pay taxes according to how you chose to be taxed: traditionally, LLCs are "pass-through entities." This means that you pay your business taxes on your personal tax form. That said, you can elect to be taxed like a corporation, if you choose to do so.
  4. File an Annual Report: this is required of all LLCs in Idaho.

What is needed to keep records for my Idaho LLC

The state of Idaho has no statutes requiring the recordkeeping of any specific documents pertaining to your LLC, but it may be helpful to keep documents regarding governance, management, taxes and other important affairs for your LLC.
