Follow these steps to start your Idaho LLC in 2026.

How to Start an LLC in Idaho (6 Steps)

Step 1: Name Your Idaho LLC

Your Idaho LLC name must be distinguishable from other business entities registered with the Secretary of State. The name must include “Limited Liability Company,” “LLC,” or “L.L.C.” It cannot contain words suggesting the LLC is a government agency or use restricted terms like “bank,” “insurance,” or “trust” without proper authorization.

Search the Idaho Secretary of State business entity database to check name availability. If you find a name you like but are not ready to file, you can reserve it for four months by filing a name reservation with the Secretary of State.

Step 2: Choose a Registered Agent

Idaho requires every LLC to designate a registered agent with a physical street address in Idaho. Your registered agent receives legal documents, service of process, and official state correspondence on behalf of your LLC during regular business hours.

You can serve as your own registered agent, but many LLC owners use a professional service for privacy and to ensure documents are always received. We recommend Northwest Registered Agent at $39 per year for reliable service and privacy protection.

Step 3: File the Certificate of Organization

To officially form your Idaho LLC, file a Certificate of Organization with the Idaho Secretary of State. The filing fee is $100. You can file online through the Idaho Secretary of State’s online portal. Standard processing takes approximately 3-5 business days.

Your Certificate of Organization must include the LLC’s name, the name and address of your registered agent, the LLC’s mailing address, and whether the LLC will be member-managed or manager-managed. You must also list the name and address of at least one organizer.

Step 4: Create an Operating Agreement

Idaho does not legally require an operating agreement, but having one is strongly recommended. This internal document defines the ownership structure, management responsibilities, profit and loss distribution, voting rights, and procedures for major business decisions.

An operating agreement reinforces your LLC’s limited liability protection and establishes clear guidelines for all members. Banks typically require one to open a business bank account. Without one, your LLC will default to Idaho’s statutory LLC rules, which may not suit your needs.

Step 5: Get an EIN

An Employer Identification Number (EIN) is a federal tax ID issued by the IRS. You need an EIN to open a business bank account, hire employees, and file federal tax returns. Even single-member LLCs benefit from obtaining an EIN because it keeps your Social Security number off business documents.

You can apply for an EIN online through the IRS website at no cost. The process takes a few minutes, and your number is assigned immediately.

Step 6: File Your Idaho Annual Report

Idaho requires every LLC to file an annual report with the Secretary of State. The filing fee is $0 — there is no charge to file. The annual report is due during your LLC’s anniversary month (the month your LLC was originally formed). You can submit the report online through the Idaho Secretary of State’s website.

The annual report updates the state with your LLC’s current registered agent, business address, and member or manager information. Even though there is no fee, failing to file on time can result in administrative dissolution of your LLC.

Idaho LLC Costs

Idaho LLC Taxes

Idaho LLCs are pass-through entities for tax purposes, meaning the LLC itself does not pay income tax. Profits pass through to members’ personal tax returns. Idaho has a flat state income tax rate of 5.695%.

Single-member LLCs are taxed as sole proprietorships by default, while multi-member LLCs are taxed as partnerships. You may elect S-corp or C-corp taxation with the IRS if it provides a tax advantage. Active LLC members pay federal self-employment tax of 15.3% on their share of LLC income.

Idaho has a state sales tax rate of 6%. If your LLC sells taxable goods or services, you must register for a sales tax permit with the Idaho State Tax Commission and collect and remit applicable sales tax.

Idaho LLC Annual Requirements

Idaho LLCs must file a free annual report during the anniversary month of formation. The report can be filed online through the Idaho Secretary of State’s website. Although there is no filing fee, missing the deadline can result in administrative dissolution.

You must maintain a registered agent with a physical Idaho address at all times. If your registered agent changes, update the information with the Secretary of State. Keep your operating agreement current and maintain separate business and personal bank accounts.

Depending on your business type and location, you may need state or local licenses and permits. Idaho does not require a general statewide business license, but specific industries are regulated by various state agencies. Check with your city or county for local licensing requirements.
