Ready to file your annual report?
Go directly to the Washington Secretary of State portal.
Your Washington LLC annual report is due during your anniversary month—the same calendar month your LLC was originally formed with the Washington Secretary of State. For example, if you formed your LLC in March 2025, your annual report must be filed by March 31, 2026, and every March 31st thereafter. You'll file Form 16-302 (Annual Report for Limited Liability Company) directly through the Secretary of State's online portal or by mail. The filing fee is $60, payable by check or credit card. Missing this deadline triggers a $10 per-month late fee and potential administrative dissolution of your LLC, which terminates your legal business status and liability protection. You can file anytime during your anniversary month—waiting until the last week risks processing delays. Set a calendar reminder for the first of your anniversary month to ensure timely compliance and avoid losing your LLC's active standing.
If you file your Washington LLC annual report late, the Washington Secretary of State's Office will assess penalties based on the number of days past your anniversary month deadline. While the exact penalty structure isn't published publicly, late fees typically range from $100–$500 depending on how overdue your filing is. Beyond financial penalties, your LLC risks administrative dissolution—the Secretary of State can cancel your business registration if your report remains unfiled for an extended period, effectively ending your legal right to operate in Washington. This dissolution carries serious consequences: you lose liability protection, cannot legally conduct business, and face complications when attempting to reinstate your company, which requires additional filing fees and processing time. To avoid these complications, mark your LLC's anniversary month on your calendar and file the annual report through the Washington Secretary of State's online portal at sos.wa.gov before the deadline. Contact their Business Services Division at (360) 725-0377 if you've already missed your deadline to determine your specific penalty amount and explore reinstatement options.
Yes, Washington law requires all LLCs to maintain a registered agent with a physical address in Washington state for receiving legal documents and official correspondence. Your registered agent receives lawsuits, tax notices, and regulatory documents on your behalf, making this a critical compliance requirement under RCW 19.86.
You can serve as your own registered agent if you maintain a physical Washington address and are available during business hours to accept documents. Alternatively, you can hire a professional registered agent service, which typically costs $75–$150 annually.
If your registered agent changes, you must file Form UBI-1003 (Change of Registered Agent) with the Washington Department of Revenue within 30 days. Failing to maintain a registered agent can result in service of process being deemed invalid and potential loss of your LLC's good standing status.
To ensure compliance, confirm your current registered agent's information on your UBI registration through the Department of Revenue's online portal immediately.
Washington's Business & Occupation (B&O) tax, administered by the Department of Revenue, taxes your LLC's gross receipts—not net profit—at rates ranging from 1.5% to 2.5% depending on your business classification. Unlike states with income tax, Washington relies on B&O tax as a major revenue source, meaning your LLC owes it regardless of profitability. If your annual gross receipts exceed $1,200, you must register and file with the Department of Revenue using Form 1040. Service and Other Activities classifications carry 1.5% rates, while Retailing is 0.471% and Manufacturing is 0.484%. This distinction directly impacts your quarterly filing obligations and tax liability—a service-based LLC pays substantially more than a retailer generating identical revenue. You may qualify for deductions if you have multi-state operations or wholesaler status, potentially reducing taxable receipts. File your B&O tax registration immediately at dor.wa.gov, then set up quarterly payment reminders to avoid penalties and interest charges.
