What an Idaho LLC Actually Costs
An Idaho LLC costs $100 to file a Certificate of Organization online ($120 by mail). The annual report is $0 — but mandatory.[1] Idaho has no franchise tax. State income tax is 5.3% flat (reduced from 5.695% via HB 40, enacted March 2025).[2]
| Cost | Amount | When Due |
|---|---|---|
| Certificate of Organization (online) | $100 | Once, at formation |
| Certificate of Organization (mail) | $120 | If filing by mail |
| Annual Report | $0 (free, but mandatory) | End of formation month, every year |
| Late annual report | Administrative dissolution | If past due |
| State income tax (owner's return) | 5.3% flat (HB 40, March 2025) | Annually |
No filing isn't free, but the annual report is. Idaho charges $100 to file, plus $0 for the annual report (still mandatory). The lowest unavoidable state cost is $100 in year-one fees and effectively $0 in ongoing state costs.
What "Free" Means for an Idaho LLC
"Free" can mean different things in Idaho formations.
- Free filing service
A provider waives their service fee and files a Certificate of Organization for $0 — but you still owe Idaho's $100 filing fee. - Free EIN
The IRS issues EINs at no charge. - Free registered agent (year one)
Some providers waive their first-year RA fee, then charge an annual fee after year one (verify the renewal terms before signing up). - Free operating agreement template
Free templates exist online. Idaho doesn't legally require an OA, but it's strongly recommended. - Free annual report
Genuinely free — Idaho is one of the few states with $0 annual report fees. But it's still mandatory.
Idaho is one of only a handful of states with a $0 annual report fee. But "free" doesn't mean "optional." Skip the filing, and Idaho may administratively dissolve the LLC if it remains delinquent. Reinstating costs $30 plus any required back annual reports. Set a calendar reminder for the end of your formation month every year.

How to Form an Idaho LLC for the Lowest Cost
The cheapest legal way to form an Idaho LLC is to file directly with the Secretary of State online.
- File Certificate of Organization online via SOS
The fastest path is the state's Online Business Services portal.![Screenshot of Idaho Secretary of State Online Business Services]( "Screenshot of Idaho Secretary of State Online Business Services")
Screenshot of Idaho Secretary of State Online Business Services Cost: $100 online ($120 mail). Online filings typically post within 1 to 3 business days, though in peak periods, it can extend to 15 to 20 business days.
- Be your own registered agent
An individual Idaho resident or a qualifying business entity can serve as your registered agent at an Idaho street address (PO boxes don't qualify). - Get a free EIN from the IRS
Apply directly with the IRS. - Draft your own operating agreement
Idaho doesn't legally require an OA under Idaho Code § 30-25. But strongly recommended. - File the (free) Annual Report by your formation month
Required every year. $0 fee, but mandatory.
Idaho Operating Agreement: Recommended, Not Required
Idaho doesn't legally require an LLC operating agreement under Idaho Code § 30-25. But a written OA is strongly recommended for liability protection.
What it should cover
- Member ownership percentages
- Profit/loss allocation
- Manager-managed vs. member-managed structure
- Voting rights
- Dissolution procedures
Idaho LLC fees founders overlook
Free annual report deadline, mail filing premium, county/city licenses
Three Idaho LLC costs catch new owners by surprise.
The first: administrative dissolution. Idaho's annual report is free, but mandatory. File by the end of your formation anniversary, or the state will dissolve your LLC. Reinstating costs $30 plus all back filings — and you lose 60 days of liability protection in the gap.
The second: the $20 mail filing premium. Mail filing costs $120 vs $100 online through SOSBiz. Online is faster and cheaper. Mail with a check is still common, but rarely worth the savings on a $20 spread.
The third: local business licenses. Idaho has no state-level business license, but cities and counties run their own.
- Boise: city Business License + property tax through Ada County.
- Idaho Falls, Twin Falls, Pocatello: city-level filings tied to gross receipts.
- Multi-city operators: a license is needed in each city.
Compared to states like Massachusetts ($500/year) or California ($800), Idaho's $0 annual report is genuinely valuable. Over 5 years, an Idaho LLC saves $1,500–$4,000 in state fees vs higher-fee states. Just don't forget to file the (free) report.
Idaho is one of the rare states with a $0 annual report filing fee through SOSBiz, due by the end of your LLC anniversary month. There are no late penalties, but if you do not file within 60 days after the deadline, the Secretary of State may administratively dissolve the entity. Reinstatement then costs $30 (or $100 same-day).

- Idaho TechHelp — Free technical assistance for product design, prototype development, and supplier scouting. Open to Idaho startups and inventors statewide. Helpful for manufacturing and product-based LLCs.
- Trailhead Boise / Idaho Startup Lab — Boise-based incubator with mentorship, peer feedback, and coworking. 2-month Idaho Startup Lab program for early-stage founders.
Common Mistakes That Cost Idaho Founders Money
- Skipping the free annual report
$0 fee, but mandatory. Miss it, and if it remains delinquent for 60 days, Idaho may administratively dissolve your LLC. - Filing by mail instead of online
Costs $20 more. No reason to file paper unless you have unusual document requirements. - Forgetting the city license
Boise, Idaho Falls, and other Idaho cities run their own licensing. Operating without one risks back taxes and fees. - Naming a registered agent at an old address
Idaho mails report reminders and service of process to the agent on file. Move without updating, and you can miss service.
Frequently Asked Questions
How long does it take to form an LLC in Idaho?
Online via SOSBiz: processing times vary. Standard filings are taking approximately 15–20 business days. Expedited and same-day service are available for additional fees.
Can I form an Idaho LLC if I don't live there?
Yes, you need an Idaho-based registered agent with a physical street address. Most non-resident founders use a registered agent service.
Is the annual report really free?
Yes, the annual report itself costs $0. The catch: if it remains delinquent for 60 days, Idaho may administratively dissolve your LLC. Reinstatement costs $30, plus any required back annual reports.
Does Idaho require an LLC operating agreement?
No, Idaho Code § 30-25-110 doesn't require one. But banks and other institutions may ask for it. Treat it as essential.
Can I be my own registered agent?
Yes — if you have an Idaho street address and can receive legal documents during business hours.
What happens if Idaho administratively dissolves my LLC?
You file the missed report and pay the $30 reinstatement. You may also need a tax clearance letter from the Tax Commission. The LLC's name remains reserved during the gap.
Are there state taxes on LLC income in Idaho?
Yes. Idaho's flat 5.3% income tax applies. LLC income flows through to owners' personal returns.
Bottom Line
A truly free Idaho LLC doesn't exist — formation costs $100. But the $0 annual report makes Idaho among the cheapest states to maintain an LLC long-term. Just don't forget to file the (free) annual report.
