Step by step

In the order most owners do them. Each step says where it happens and links to the official page.

  1. With the state

    Check your name is free

    Search the Idaho Secretary of State's business records to check no business already uses your name, or one too close to it. An LLC's name must also end with "LLC" or a similar ending.

  2. Your records

    Choose a registered agent

    Every LLC and corporation in Idaho needs a registered agent: a person or company with a street address in Idaho who receives legal papers and state notices for it. You can be your own, or pay a registered agent service.

  3. With the state

    File your Certificate of Organization

    File it with the Idaho Secretary of State online through SOSBiz. The state's fee is $100 online; paper filings cost $20 more. Once it's filed, your business exists.

  4. Your records

    Write an operating agreement

    It sets out who owns the LLC, how decisions are made and what happens if someone leaves. It isn't filed with the state: keep it with your records. A lawyer can help you write one.

  5. With the IRS

    Get an EIN from the IRS

    An Employer Identification Number is your business's tax number, for taxes, hiring and a bank account. Apply once your Certificate of Organization are filed. It's free from the IRS: with a Social Security number or ITIN, you can apply on the IRS's own site and get it at once. Watch out for look-alike sites that charge for it.

  6. With the state

    Register for state taxes

    If you'll sell taxable goods or services, or have employees, register with the Idaho State Tax Commission through the online Idaho Business Registration (IBR) application. Employers, and Idaho corporations, use the same application to set up a withholding account and an unemployment insurance account with the Idaho Department of Labor.

  7. City or county

    Check local licenses and permits

    Idaho has no state business license; registering with the Secretary of State is a registration, not a license. Some trades and professions need a state license (the Business Wizard at business.idaho.gov lists them), and your city or county may require a local business license, a home occupation permit or other permits.

  8. Your records

    Open a business bank account

    Keep the business's money apart from your own: it keeps your records clear at tax time, and keeps the LLC separate from you. Banks usually ask for your filed Certificate of Organization and your EIN.

  9. With the state

    Put the yearly report in your calendar

    Every Idaho LLC files an annual report with the Secretary of State by the end of the month it was formed in, each year starting the year after it's formed. It's free, and you can file online through SOSBiz. The state can start dissolving a business whose report isn't in by the due date.
