Idaho LLC Formation Guide

This guide will help you set up an LLC in Idaho and find a top-rated Idaho registered agent. It includes step-by-step instructions for obtaining tax IDs and filing documents.


Because they are affordable to set up, offer flexibility for the owners and are simple to manage, LLCs are the most preferred business structure. Your LLC legalizes your business and limits your personal liability. It also allows you to have tax flexibility. As you go through this process, the following steps will guide you.

Step-by-Step Idaho LLC Instructions

  2. Designate a registered agent

    Before you can file to officially create your Idaho LLC, it is necessary to determine who your Idaho registered agent will actually be. Register agents are the legal representative of a business that receives notices about lawsuits and other legal notices.

    Every LLC must have a registered agent according to state law. When you file Idaho articles, the registered agent is identified.

    • Minutes of meetings
    • Operating agreement
    • EIN verification letter
    • Modifications and other filings to the LLC during its lifetime


  5. Make the Operating Agreement

    An Operating Agreement is the governing document of the LLC. This document outlines the rules and procedures for how the LLC will operate, such as holding an annual meeting. The agreement will be reviewed and approved at your organization meeting.

  6. Organise the Organizational Meeting

    The organizational meeting is the first meeting of members of an LLC. To conduct this meeting, you will need to have your filed articles of organisation and your operating agreement. Keep a record of the meeting and keep it in your company records book.

  7. Register for a Federal Employer Identification Number.

    An EIN is required for any LLC that has more than one member, or hires employees. A bank account opening requires an EIN.

  9. Consider Electing C-Corp Taxation or S-Corp Fiscal

    Your LLC will automatically be subject to pass-through taxation. However, the majority of LLCs maintain this tax classification. Some LLCs can choose to elect S-Corp and C-Corp tax treatment.

    • S-Corp is a tax-saving tool that can be used by owner-employees earning more than $75,000 annually.
    • Double taxation is a problem for C-Corps: members pay taxes on distributions and the corporation pays taxes. You may be eligible for C-Corp tax treatment if your profits exceed $250,000 or you offer employee benefits.
  10. Get Business Licenses and Permits

    You must have the appropriate licenses and permits to run your business legally. It is easy to find the right licenses and permits for your state and federal business.
