Forming an LLC in Idaho

Located in the northwestern United States, Idaho is a geographically diverse state that’s home to around 1.8 million people. The main industries in the state include agriculture, manufacturing, mining, tourism and forestry.

For most business owners, the fastest and easiest way to start a business in Idaho is by creating an LLC. A limited liability company (LLC) is a type of business entity that’s ideal for startups and small- to medium-sized businesses. You get the advantages and protections of larger Idaho corporations but with much simpler rules and regulations.

Briefly, the benefits of starting a Idaho LLC include:

  • Separating and limiting your personal liability from your business liability and debts
  • Quick and simple filing, management, compliance, regulation and administration of your Idaho LLC
  • Easy tax filing and potential advantages for your tax treatment

Six Quick Steps to Forming Your Idaho LLC

This guide has plenty of information on how to form your Idaho LLC, but you can break down the basics of forming a business in ID into just a few simple steps.

STEP 1: Gather Information for Your Members

First, you need to gather basic information about your LLC, including the names and addresses of the managers or members.

The LLC members are typically the people who own and run the business. They are also the ones who can take profits out of the business to pay themselves.

STEP 2: Choose a Unique Business Name for Your Idaho LLC

You will need a distinctive and original name for your LLC that’s not used by any other business in ID. To find out if another company is using your chosen business name, carry out a business entity name search on the ID Secretary of State website.

There are a few rules you’ll need to follow when choosing an LLC name. You can find out more in our guide to naming your Idaho LLC.

Learn about Idaho LLC business naming rules.

STEP 3: Provide an Official Address for Your ID LLC

Every Idaho LLC must have a designated street address. That could be your home address (if you’re running the company from your residence), your company’s office building or any physical address of your preference. The address must be inside the state of Idaho, but it cannot be a P.O. Box.

STEP 4: Assign a Idaho Registered Agent

Every ID LLC must have a “Registered Agent.” This is an official position; the Registered Agent is someone who receives official legal and tax correspondence and has responsibility for filing reports with the Idaho Secretary of State.

This position can be filled by you, another manager in the business or a dedicated Registered Agent service. Your Registered Agent must have a physical street address in Idaho and must be present to receive important documents for your company during business hours.

At Incfile, all of our packages include a Idaho Registered Agent service that is free for the first year and just $119 per year afterward. We also have a dashboard where you can log in and easily view any document your Registered Agent has received on your behalf.

STEP 5: Get an Employer Identification Number (EIN) from the Internal Revenue Service

You will need an EIN to identify your business with the IRS. You use this number when filing and paying taxes or when submitting payroll information and payments for your employees. You can obtain one directly from the IRS, or we can get one for you as part of the Idaho LLC business formation process.

STEP 6: File Articles of Organization with the Idaho Secretary of State

Once you've gathered all the information for your LLC, you’ll need to file a formal document with the ID Secretary of State. This document is known as your “Articles of Organization,” and filing the document creates your Idaho LLC. Here’s what is typically included:

  • Your business name and address
  • Details of your Registered Agent
  • Names of managers or members of the LLC at the time of filing
  • Addresses of managers or members of the LLC at the time of filing
  • Name of the incorporator

You can file your Idaho Articles of Organization online, mail in a form or have Incfile do it on your behalf. There is a fee to file and start an LLC in Idaho, but you only need to file your Articles of Organization once.
