How to start an LLC in Idaho
To start an LLC in Idaho, you file a Certificate of Organization with the Idaho Secretary of State, pay the $100 state filing fee, and appoint a registered agent with an Idaho street address. You'll also need a unique business name, an operating agreement, and an Employer Identification Number (EIN) from the IRS.
Why form an LLC in Idaho
An LLC is the most common business structure for entrepreneurs in Idaho because it combines personal liability protection with straightforward tax treatment. Your personal assets stay separate from business debts and legal claims — without the complexity of a corporation.
Idaho also keeps the ongoing cost low. The annual report fee is $20, and there's no state-level franchise tax on LLCs. For a small business that wants real legal protection without a heavy compliance burden, Idaho is a practical place to form.
The Idaho Department of Commerce offers workforce development reimbursements of up to $3,000 for training new full-time employees — one of the more tangible state incentives available to small businesses here.
Idaho LLC fees and requirements
The main cost to form an Idaho LLC is the $100 state filing fee paid when you submit your Certificate of Organization. There's no publication requirement and no state franchise tax on LLCs.
- Certificate of Organization filing fee: $100 (online)
- Registered agent: required — must have an Idaho street address
- EIN: free through the IRS website
- Operating agreement: not required by state law, but recommended
- State tax ID: may be required depending on your business type and activities — check with the Idaho State Tax Commission
Annual report and ongoing compliance
Idaho LLCs must file an annual report with the Secretary of State each year to stay in good standing. The report is due by the end of the month in which your LLC was originally formed — so if you formed in March, your annual report is due every March. The filing fee is $20 and you can file online through the Secretary of State's business portal.
If you miss the annual report deadline, Idaho will administratively dissolve your LLC after a grace period. That means your LLC loses its legal standing — and reinstating it takes extra paperwork and fees. Filing on time is the easiest way to avoid that.
If your LLC has employees, you'll also need to register with the Idaho Department of Labor for unemployment insurance purposes.
