Form an LLC in Idaho — or start trading today

Forming an Idaho LLC yourself is genuinely affordable — the $100 Certificate of Organization fee and a free annual report make ongoing costs effectively zero. But "form it yourself" still hides a queue: you file with the state, wait for approval, then apply to the IRS for an EIN. Until that EIN lands, no bank or payment processor will fully onboard you. A ready-made Wyoming LLC removes the queue — its EIN already exists, so the day the transfer completes you can open a US business bank account, connect Stripe, and invoice.

Idaho LLC overview

Idaho is a hidden gem for LLC formation. While it charges $100 for filing, the state requires no fee for its annual report — making ongoing costs effectively zero.

Boise has emerged as one of America's fastest-growing tech hubs, attracting entrepreneurs from higher-cost states. Idaho's economy also thrives on agriculture, manufacturing, and outdoor recreation. Micron Technology is headquartered here, drawing relocating tech workers from California, Oregon and Washington.

Idaho's 5.695% flat income tax is the main consideration. For non-residents with no Idaho operations, this does not apply. Arizona ($50, $0/year) is cheaper upfront, but Idaho's $0 annual cost matches it ongoing.

Idaho LLC costs and fees

All fees below are sourced from the Idaho Secretary of State fee schedule.

Step-by-step: how to form an Idaho LLC

Step 1: Choose your LLC name

Search for available names on the Idaho Business Entity Search. Your name must include "Limited Liability Company," "LLC," or "L.L.C." Ensure the name is distinguishable from existing entities on file.

Step 2: Appoint a registered agent

Every Idaho LLC must have a registered agent with a physical street address in Idaho. The agent must be available during normal business hours to accept legal documents on behalf of the LLC.

Step 3: File Certificate of Organization

File online through the Idaho Secretary of State. The filing requires:

• LLC name with designator
• Registered agent name and Idaho address
• Principal address
• Mailing address
• Name and address of organizer(s)
• $100 filing fee

Step 4: Create an Operating Agreement

While not always legally required in Idaho, an Operating Agreement is essential for banking, tax compliance, and internal governance. It establishes member rights, profit distribution, and management structure. We include a custom Operating Agreement in every formation package.

Step 5: Obtain an EIN

Apply for an Employer Identification Number (EIN) from the IRS. This is your LLC's tax ID number, required for banking, hiring, and tax filings. Online application is available for those with an SSN; fax or mail application for international applicants without an SSN. (A ready-made Wyoming LLC skips this step entirely — the EIN already exists.)

Step 6: Register for Idaho taxes (if applicable)

If you will sell taxable goods or services in Idaho, register with the Idaho Department of Revenue for applicable tax accounts including sales tax and income tax withholding if you have employees.

Annual compliance requirements

1. Annual report: Due during anniversary month. Fee: $0 (free). Must still file or face dissolution.
2. Federal tax filing: Form 5472 with pro forma 1120 for foreign-owned LLCs.
3. Idaho income tax: 5.695% flat rate on Idaho-sourced income.
4. Sales tax: 6% statewide.
5. Registered agent: Maintain agent with ID address.
6. FinCEN BOI Report: Required.

Idaho taxes for LLCs

Idaho's free annual report makes it one of the cheapest for ongoing maintenance. Non-residents with no Idaho operations pay nothing annually.

Processing times

Idaho offers affordable expedited processing at just $20. Even so, a ready-made Wyoming LLC is faster end-to-end because its EIN — the thing banks ask for first — already exists.
