How to start an LLC in Washington State?

Forming an LLC in Washington provides flexibility, limited liability protection, and tax advantages for small and medium-sized business owners. Here's how to do it step by step:

1. Choose a Name for Your LLC

Your LLC name must be unique and distinguishable from existing businesses registered in Washington.

• It must end with “Limited Liability Company,” “LLC,” or “L.L.C.”
• Check name availability via the Washington Secretary of State's business name search tool.
• You may reserve a name for 180 days for a $30 fee (optional).

2. Appoint a Registered Agent

You must designate a registered agent with a physical address in Washington.

• This can be an individual or a registered agent service.
• The agent is responsible for receiving legal documents and official notices.

3. File a Certificate of Formation

Submit the Certificate of Formation with the Washington Secretary of State.

• File online or by mail.
• Filing fee: $200 (online) or $180 (by mail)
• Processing time: 2–5 business days (online), longer by mail.

4. Create an Operating Agreement (Recommended)

Although not legally required, an Operating Agreement defines the LLC’s structure, ownership, and operating procedures.

• Helps prevent disputes and supports legal separation between personal and business assets.

5. Obtain an EIN (Employer Identification Number)

Apply for an EIN from the IRS for free via irs.gov.

• Required to open a business bank account, hire employees, and file federal taxes.

6. File the Washington State Business License Application

You must file a Business License Application with the Washington Department of Revenue.

• Fee: $90
• Register your trade name and obtain other necessary local or state licenses here.

7. Comply with Ongoing Requirements

• Annual Report: File annually with the Secretary of State ($60 fee).
• Taxes: Washington has no state income tax but levies a Business & Occupation (B&O) tax on gross receipts.
• Additional industry-specific licenses may apply.
