  5. Establish Company Records

    Your LLC must keep correct and complete books and records. Your filed articles of organization are the first documents for your LLC’s records. Your LLC will generate many other official records such as:

    • Meeting minutes
    • Operating agreement
    • EIN verification letter
    • Amendments and other filings made to the LLC throughout its lifetime

    Organizations need a secure, centralized tool for managing and accessing sensitive records. Our Records Manager software offers a simple, efficient way for LLCs to store records, track members and managers, and customize meeting notifications.

  6. Create the Operating Agreement

    Draft an Operating Agreement (potentially using a template) which is the governing document for the LLC. It defines the formalities of how the LLC will run itself such as holding an annual meeting. You will review and adopt the agreement at your organizational meeting.

  7. Hold the Organizational Meeting

    The first meeting of the members of the LLC is the organizational meeting. You will need your filed articles of organization and your operating agreement in order to conduct this meeting. Keep minutes of this meeting and store them in your company record book.

  8. Get a Federal Employer Identification Number (EIN)

    If your LLC has more than one member or will hire employees, it must obtain an EIN. An EIN is also often required to open a bank account.

    Agency:Internal Revenue Service (IRS)

    IRS Form SS-4

    Filing Method:

    Mail, phone, fax, or online.

    IRS fee:



    Immediately online or by phone. 4 business days by fax. 4-5 weeks by mail.


    The IRS website is only available during certain hours. Print your EIN before closing your session. For additional guidance, see IRS Pub 1635: Understanding Your EIN.

  9. Get Washington State Tax Identification Numbers/Accounts

    The Unified Business Identifier (UBI) issued to your LLC by the Secretary of State is also your organization's id with the Department of Revenue.

    You must register with the Department of Revenue if you meet any of the following conditions:

    • Your business is required to collect sales tax.
    • Your gross income is $12,000 per year or more.
    • Your business is required to pay taxes or fees to the Department of Revenue.
    • You are a buyer or processor of specialty wood products.
    Submit to:
    Washington Department of Revenue
    Washington Department of Revenue - New Business Tax Basics Booklet
    Form BLS-700-028: Washington Business License Application
    Filing Method:
    Mail or online
    ~2 business days online. ~21 business days by mail.
  10. Consider Electing S-Corp or C-Corp Taxation

    By default, your LLC receives pass-through taxation and the vast majority of LLCs keep this tax classification. Some LLCs benefit from electing S-Corp or C-Corp tax treatment:

    • S-Corp treatment can help owner-employees who earn more than ~$75,000 per year save on self-employment taxes. File Form 2553: S-Corp Election.
    • C-Corps suffer from double taxation: the corporation pays taxes on profits then members pay taxes on their distributions. If profits exceed $250,000 per owner, you provide employee benefits, or you will re-invest most of your profit in the business, you may benefit from the low tax rates on retained earnings under C-Corp treatment. File Form 8832: C-Corp Election.
  11. Obtain Business Licenses & Permits

    To run your business legally, you must obtain applicable licenses and permits. The easiest way to navigate the wide range of federal, state, and local requirements is to search by your business type and locality using the Small Business Administration Business License & Permit look-up tool.

    For more details, see our Washington annual report information center page.

    As your LLC grows, you will need to demonstrate your company’s good standing to banks, customers, and other state agencies. After all the work involved in forming your Washington LLC, don’t let a missed annual report filing cause your new business to fall out of compliance.

    Tracking and filing annual reports on your own can be time consuming and lead to accidental lapses. Protect your LLC’s good standing with Managed Annual Report Service, which tracks and automatically files reports on time, every time, so you can focus on your business.
