How to Form an LLC in Idaho
What it costs, the steps, and what comes after. Updated for 2026.
Verdict: an LLC in Idaho costs $100 to file. You can file it yourself online in about an hour, and you do not need a lawyer for a straightforward single-owner business.
What it costs in Idaho
At $100, Idaho sits in the middle of the pack on formation cost. Idaho requires a report but charges no fee for it. Annually, with no fee. Missing it can still put your LLC out of good standing, so the deadline matters even though the cost does not.
| Cost | Amount |
|---|---|
| File articles of organization | $100 |
| Annual report | No fee |
| Registered agent, if you hire one | $100 to $300 a year |
| EIN from the IRS | Free |
Roughly $100 in state fees for your first year if you act as your own registered agent. Fees change without much notice and some states charge different amounts online versus by mail, so confirm the current fee with the Idaho filing office before you file.
The steps in Idaho
1. Pick a name. It must be distinguishable from every other business registered in Idaho and include an LLC marker. Search the state business database first.
2. Appoint a registered agent with a physical Idaho street address.
3. File the articles of organization with the state and pay $100. This is the step that creates the LLC.
4. Write an operating agreement. Idaho may not require one. Have one anyway, because banks ask for it and it helps show your LLC is genuinely separate.
5. Get an EIN free from the IRS in about fifteen minutes, then open a business bank account and run every business dollar through it.
The full step by step guide covers each of these in detail.
After you file
Idaho requires a report but charges no fee for it. Annually, with no fee. Missing it can still put your LLC out of good standing, so the deadline matters even though the cost does not. Keep business and personal money strictly separate, because mixing them is the most common reason a court sets LLC protection aside.
Once the business is profitable, the bigger decision is a tax one rather than a legal one. Electing S corporation treatment can cut self-employment tax, but it costs real money to run and it shrinks your qualified business income deduction. Our S corp calculator works out whether it is worth it on your numbers. Note that it covers federal tax only, so check how Idaho treats S corps as well.
One thing you can skip: beneficial ownership reporting. That requirement no longer applies to companies formed in the United States, after a FinCEN rule issued in March 2025 narrowed it to entities formed under foreign law.
