Washington Registered Agent Requirement

Every Washington LLC must maintain a registered agent with a physical street address in the state. The agent accepts legal documents and official notices during business hours. You can act as your own agent, name another person, or hire a commercial service.

The agent's address is part of the public record, so home-based owners often use a commercial agent to keep their home address private. If your agent changes, you must update the Secretary of State so legal notices keep reaching you. Our registered agent guide explains the options.

Filing the Washington Certificate of Formation

The Certificate of Formation officially creates your LLC. You file it online with the Secretary of State or by mail. The form asks for your LLC name, registered agent details, and the organizer's signature.

1. Complete the Certificate of Formation form.
2. Pay the filing fee of approximately $180.
3. Submit online for faster processing.
4. Keep the confirmation for your records.

Verify every detail before submitting. A rejected filing means correcting the issue and waiting through review again, so a few extra minutes of review can save you time. The online system walks you through each required field.

Washington LLC Fees and Processing Time

Washington's formation fee is higher than many states. The Certificate of Formation costs approximately $180. Online filings are usually processed within a few business days, while mailed filings take longer. As of 2026, the Secretary of State processes most online LLC filings quickly, though turnaround can vary. For a broader cost picture, see our guide on how much an LLC costs.

Budget for the business license as well. The license fee is separate from formation, and the annual report ranges from approximately $60 to $90 depending on your gross receipts.

Washington Business License and Post-Formation Steps

Washington is one of the few states where a business license is required for most LLCs. You apply through the Department of Revenue's Business Licensing Service, and the fee is separate from formation. After that, finish the setup:

• Get a free EIN from the IRS for banking and payroll. See our EIN guide for the steps.
• Draft an operating agreement that defines ownership and management.
• Register for Washington state tax accounts through the Department of Revenue.
• Open a business bank account in the LLC's name.

Washington also has a business and occupation (B&O) tax on gross receipts. Most new LLCs register for it at the same time they apply for the business license, so you can handle both in one application.

Washington Annual Report and Ongoing Requirements

Washington LLCs file an annual report with the Secretary of State. The fee ranges from approximately $60 to $90 depending on your gross receipts. You also need to keep your business license current and renew it as required. Confirm the current fees on the Secretary of State and Department of Revenue websites, since they can change. Missing the annual report deadline can put your LLC in bad standing, so set a reminder.
