Idaho Business License: What’s Actually Required (2026)

Last updated: August 8, 2026

Idaho does not have a general state business license. Most Idaho businesses need three things instead: an entity registered with the Secretary of State ($103 for an LLC filed online), a free seller’s permit from the Idaho State Tax Commission if you sell taxable goods or services, and a city license where your city requires one. Certain trades and professions need their own state licenses on top.

That answer surprises people, because nearly every checklist says “get your business license” as if one document exists. In Idaho, what that phrase really refers to is a small stack of registrations, and which ones apply depends on what you sell and where you operate.

What Idaho Actually Requires

• Entity registration — file a Certificate of Organization with the Idaho Secretary of State ($103 online). Sole proprietors skip this but file an assumed business name (DBA) if operating under any name that isn’t their own.
• Seller’s permit (free) — required if you sell or rent taxable goods, or charge for things like admissions or recreation. Issued by the Idaho State Tax Commission through the state Business Registration system.
• City business license — Idaho cities set their own rules. Some license most businesses, others license only specific activities (alcohol, childcare, mobile vending, contractors). Check the city clerk where you’ll actually operate.
• Occupational or industry license — only for regulated fields: contractors register with the state, cosmetologists license through the state board, daycares license through Health & Welfare, and so on.
• EIN — free from the IRS, needed the moment you hire or open a business bank account.

What It Costs

Item	Cost	Renewal
Idaho LLC (Certificate of Organization, online)	$103	Annual report: $0
Seller’s permit (State Tax Commission)	Free	None
Assumed business name (DBA)	$25	—
City license	Varies by city and activity	Usually annual

Idaho is one of the cheaper states to get legal in: the state’s two core registrations — the LLC filing and the seller’s permit — total $103, and Idaho’s LLC annual report costs nothing to file.

How to Get Set Up, In Order

1. Register the entity. File online with the Idaho Secretary of State. This is the legal foundation everything else attaches to — the seller’s permit, city license, and bank account are all issued to this entity.
2. Get the seller’s permit. Register through Idaho’s online Business Registration system (covers the State Tax Commission and Department of Labor in one application). Online applications typically process in 10–15 business days.
3. Check your city. Call or search the city clerk’s site for the licenses that apply to your activity at your address — including home businesses, which some Idaho cities license and zone.
4. Add industry licenses if regulated. Idaho’s Business Wizard at business.idaho.gov walks through exactly which state licenses your industry triggers.

Idaho Licenses by Industry

The general answer above changes once your industry is regulated. We keep verified Idaho requirements for the industries new owners ask about most:

• Food trucks in Idaho — health district permits and commissary rules
• Cleaning services in Idaho — where a license is and isn’t required
• Salons in Idaho — cosmetology board licensing
• HVAC businesses in Idaho — state contractor and specialty licensing

Frequently Asked Questions

Does Idaho require a business license?

No. Idaho has no general state business license. Most Idaho businesses need three things instead: registration of the business entity with the Secretary of State ($103 for an LLC filed online), a free seller’s permit from the Idaho State Tax Commission if they sell taxable goods or services, and a city business license where the city requires one.

How much does an Idaho seller’s permit cost?

Nothing. Idaho’s seller’s permit is free. You register through the state’s online Business Registration system (or paper form IBR-1), and the permit typically arrives within 10-15 business days for online applications.

Do sole proprietors in Idaho need a business license?

Idaho imposes no general license on sole proprietors. A sole proprietor selling taxable goods still needs the free seller’s permit, needs any city license required where they operate, and needs a DBA (assumed business name) filing if operating under a name other than their own.
