How to Form an LLC in Idaho

Forming an LLC in Idaho is a straightforward process that provides liability protection and tax flexibility for business owners. The initial filing fee is $100, filed with the Idaho Secretary of State.

Step 1: Choose Your Business Name

Your LLC name must be distinguishable from existing business entities registered in Idaho. The name must include "LLC" or "Limited Liability Company." Check name availability through the Secretary of State's website before filing.

Step 2: File Articles of Organization

Submit your Articles of Organization to the Idaho Secretary of State with the $100 filing fee. This document establishes your LLC as a legal entity. Processing times vary but typically take 5-10 business days.

Step 3: Obtain an EIN

Apply for a federal Employer Identification Number (EIN) from the IRS at no cost. This is required for tax filing, opening a business bank account, and hiring employees.

Step 4: Register for State Taxes

Register with the Idaho State Tax Commission for applicable tax accounts. You will need a sales tax permit to collect the 6% state sales tax. Idaho has a state income tax that affects LLC pass-through taxation.

Ongoing Costs

Idaho does not impose an annual franchise tax on LLCs, keeping ongoing costs low.

Idaho LLC Tax Advantages

While Idaho does impose a state income tax, the LLC structure offers flexibility in how income is taxed. The 6% state sales tax requires proper collection and remittance procedures.
