6. How to Register an LLC in Idaho

Step 1: Appoint a Registered Agent

Choose a registered agent with a physical street address in Idaho before submitting your LLC formation documents. The registered agent is responsible for receiving legal notices, government correspondence, and compliance documents on behalf of your LLC.

Step 2: File the Certificate of Organization

File the Certificate of Organization with the Idaho Secretary of State. This filing officially creates your Idaho LLC as a legal business entity.

State filing fee: $100

Step 3: Register for State Taxes (If Applicable)

If your Idaho LLC will have employees, sell taxable goods, or collect sales tax, you may need to register with the Idaho State Tax Commission . Not all LLCs are required to register for state taxes, but most active businesses will need at least one tax account.

Step 4: Annual Report Filing

Idaho requires LLCs to file an annual report to remain in good standing. The report is filed online with the Idaho Secretary of State and there is no filing fee.

Failure to submit the annual report may result in administrative dissolution of your LLC, making it difficult to conduct business or open financial accounts.

Step 5: Adopt an Operating Agreement

Idaho does not legally require an Operating Agreement, but it is strongly recommended. This internal document defines ownership percentages, management authority, voting rights, and profit distribution.

While not filed with the state, an Operating Agreement is commonly requested by banks, investors, and payment processors and helps reinforce your LLC’s limited liability protection.

Step 6: Obtain an EIN

An Employer Identification Number (EIN) is required to open a business bank account, hire employees, and file federal taxes. You can apply for free directly through the IRS: IRS EIN Application .

Step 7: Open a Business Bank Account

After completing Idaho LLC registration, opening a dedicated business bank account helps separate personal and business finances and protects your limited liability status.

Most U.S. banks require the following documents before opening an account:

• Approved Certificate of Organization issued by the Idaho Secretary of State
• Your LLC Operating Agreement
• Employer Identification Number (EIN)
• Valid government-issued photo ID of the owner or authorized manager

Many Idaho LLC owners open their business bank account shortly after receiving their EIN to avoid delays in payments, invoicing, or merchant account setup.

7. Tips to Stay Compliant

• Maintain an active registered agent in Idaho
• File your Idaho annual report on time (free of charge)
• Keep accurate financial, ownership, and tax records

9. Federal Requirements

1. Employer Identification Number (EIN)

Most businesses formed through Idaho LLC registration must obtain an Employer Identification Number (EIN) from the Internal Revenue Service (IRS). The EIN serves as your federal tax ID and is required for banking, hiring employees, working with payment processors, and filing federal tax returns.

You can apply for an EIN directly with the IRS: IRS EIN Application . Non-U.S. founders can apply without a Social Security Number.

2. Federal Tax Classification

By default, Idaho LLCs are treated as pass-through entities for federal tax purposes. This means the LLC itself does not pay federal income tax; instead, profits and losses pass through to the owners.

• Single-member LLC: Income is typically reported on Schedule C (Form 1040) .
• Multi-member LLC: Files an informational return using IRS Form 1065 .
• S Corporation election (optional): Eligible Idaho LLCs may elect S-Corp tax treatment by filing IRS Form 2553 to potentially reduce self-employment taxes.

Foreign-owned Idaho LLCs may have additional federal filing obligations, such as IRS Form 5472 and Form 1120, even if no U.S. income is generated. Many founders consult a qualified tax professional to ensure full compliance.
