Why an LLC is Ideal for a Marketplace in Washington

Steps to Form Your LLC

  1. Choose a Name: Select a unique name for your LLC that complies with Washington state law and is distinguishable from existing business names. Check name availability on the Washington Secretary of State's website.
  2. Appoint a Registered Agent: Designate a registered agent in Washington to receive official legal and tax documents on behalf of your LLC. This can be an individual or a registered agent service.
  3. File Certificate of Formation: File a Certificate of Formation with the Washington Secretary of State. This document officially creates your LLC and includes essential information like the LLC's name, registered agent, and business address. The filing fee is $200.
  4. Create an Operating Agreement: Draft an operating agreement outlining the ownership structure, member responsibilities, and operating procedures of your LLC. While not required in Washington, it is highly recommended.
  5. Obtain an EIN: Apply for an Employer Identification Number (EIN) from the IRS. This is required if your LLC has more than one member or plans to hire employees. It's free to obtain online.
  6. Register with Washington DOR: Register your LLC with the Washington State Department of Revenue (DOR) to obtain a Unified Business Identifier (UBI) number and comply with state tax requirements, including the Business and Occupation (B&O) tax.
  7. Comply with B&O Tax: Understand and comply with Washington's Business and Occupation (B&O) tax, which is a gross receipts tax. Marketplace businesses may fall under specific B&O tax classifications with rates ranging from 0.138% to 3.3%.
