Idaho LLC Cost and Filing Fees (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

The main cost of an Idaho LLC is the one-time Certificate of Organization filing fee paid to the Idaho Secretary of State. Idaho's biggest advantage is that the required LLC annual report is free ($0). A federal EIN from the IRS is free, and a seller's permit from the Idaho State Tax Commission is also free - so beyond the formation fee and optional services, ongoing state costs are minimal.

What an Idaho LLC Actually Costs

Idaho is one of the more affordable states in which to run a limited liability company because it charges no annual report fee. The only unavoidable state charge to create the entity is the Certificate of Organization filing fee paid to the Idaho Secretary of State. After that, keeping the LLC alive each year costs nothing at the state level unless you use paid services. This makes Idaho cheaper over time than states that charge annual franchise taxes or recurring report fees. For the broad picture of what forming an LLC involves, see the national how to form an LLC hub and our state formation guides.

The rest of your costs are optional or situational: a name reservation if you want to hold a name before filing, expedited processing if you need faster turnaround, a commercial registered agent if you prefer privacy, and professional or accounting help. Because the state periodically updates its schedule, we describe each fee and point you to the official source rather than quoting a number that may have changed. Always confirm the current amount on the Idaho Secretary of State fee schedule before you file.

Certificate of Organization Filing Fee

To create an Idaho LLC, you file a Certificate of Organization with the Idaho Secretary of State, typically online through the SOSBiz portal. The Certificate of Organization lists the LLC name, the registered agent and registered office, the principal address, and the governing authority (member-managed or manager-managed). The state charges a filing fee for this document, and paper filings may carry a manual processing surcharge that online filings avoid. Because Idaho updates its schedule, confirm the exact online and paper amounts on the Secretary of State fee schedule before you submit. Once filed and approved, the entity exists and appears in the Idaho business entity search.

You should also adopt an operating agreement. Idaho does not file it and does not charge for it, but it governs ownership and management internally and is strongly recommended even for a single-member LLC. If you use a brand name different from your registered name, a DBA (assumed business name) filing carries its own small fee.

The Free Idaho Annual Report

Idaho's standout feature is its free annual report. Every Idaho LLC must file an annual report with the Secretary of State to keep its registration and contact information current, but the filing fee is $0. The report is due by the end of the LLC's anniversary month - the month in which the LLC was originally organized - each year. The state sends a reminder, and you can file it online in minutes. See our Idaho annual report guide for the exact steps.

Even though the report is free, filing it is not optional. If you miss the deadline, the Secretary of State can administratively dissolve your LLC, which strips your liability protection and forces reinstatement. So the "cost" of the annual report is really the discipline of filing on time, not money. This is a meaningful difference from states that charge annual franchise taxes or report fees running into the hundreds of dollars.

Idaho Taxes: Income Tax and the Free Seller's Permit

Idaho has a state income tax, and this is where ongoing obligations, rather than flat fees, come in. By default an LLC is a pass-through: single-member LLCs are disregarded and multi-member LLCs are taxed as partnerships, so the profit flows to the owners' Idaho individual income tax returns. There is no separate charge to be taxed this way, but you owe income tax on your share of profit. An LLC that elects corporate or S-corporation treatment files the corresponding return. For how these returns interact, see our Idaho LLC tax filing guide and the business tax hub.

If you sell taxable goods, you must register with the Idaho State Tax Commission for a seller's permit (sales tax permit), which is issued free of charge. You then collect Idaho sales tax and remit it on the Tax Commission's schedule. Employers also register for Idaho withholding and pay unemployment insurance tax; those are ongoing obligations tied to payroll, not one-time formation fees. A free federal EIN is required to hire and to open most business bank accounts; get it before you register for state tax accounts, or use our Idaho EIN guide.

Optional and Ongoing Costs

Beyond the required state fees, several optional costs can add up depending on your situation:

• Registered agent service. You can be your own registered agent for free with an Idaho street address, or pay a commercial service roughly $100-$150 per year for privacy and reliable handling of legal mail.
• Name reservation. A small fee holds a name for a set period before you file, useful if you are not ready to organize yet.
• Expedited processing. An additional fee speeds up review if you need the LLC approved quickly.
• Local licenses and permits. Some Idaho cities and regulated professions require licenses; see the business license overview.
• Professional help. Attorney or CPA fees for drafting the operating agreement or handling taxes are optional but common.

If you later close the business, factor in dissolution: filing a statement of dissolution is a final step covered in how to dissolve an LLC in Idaho. Overall, because Idaho charges no annual report fee and no franchise tax, its multi-year cost of ownership is among the lowest in the country - the formation fee is the main expense, and most recurring obligations are tax filings rather than flat charges. If you are unclear on any term, the glossary defines the essentials.
