Research summary and authoritative findings for: "Washington compliance legal requirement summary" (target audience: US business owners, LLC founders). I collected official guidance from Washington state agencies and FinCEN to assemble the core compliance checklist, key deadlines, and citations you can use to build the requested blog post and newsletter.Key takeaways (concise):- Secretary of State (Corporations & Charities): All domestic and foreign business entities must file an Annual Report every year to maintain active status; the annual report is due by the last day of the month in which the business was originally formed or registered.

You may file up to 180 days before the expiration date. Failure to file leads to delinquent status and potential administrative dissolution.- Department of Revenue (DOR): Washington’s Business & Occupation (B&O) tax is a gross receipts tax (no deductions for costs); rates vary by classification.

New businesses register with DOR/Business Licensing Service; filing frequencies: monthly due on the 25th of the following month, quarterly due by the month following quarter close, and the annual return due date moved to April 15th.- Department of Labor & Industries (L&I): Employers must address industrial insurance/workers’ compensation and follow L&I employer coverage rules and reporting — register as an employer with L&I and obtain required coverage.- Employment Security Department (ESD): Employers must register for unemployment insurance / employer taxes and follow ESD employer reporting and payroll tax requirements.

ESD also has employer resources (including PFML guidance links).- FinCEN / BOI (Corporate Transparency Act): As of the interim final rule published March 26, 2025, FinCEN removed BOI reporting requirements for U.S.-formed (domestic) companies; only certain foreign-formed entities that register to do business in the U.S. remain as “reporting companies” with short filing deadlines.

Check FinCEN guidance for the specific deadlines that apply to foreign reporting companies.Recommended compliance checklist for Washington LLCs (actionable items):1) Formation & Secretary of State filings - File Certificate of Formation with Secretary of State to form a domestic LLC. - Submit the Initial Report (when applicable) within the state’s required window (SOS guidance shows initial/first reports and procedures). - Appoint and maintain a Registered Agent (WA requires a registered agent or in-state address per SOS rules). - File Annual Report each year by the last day of the LLC’s formation/registration month (SOS allows filing up to 180 days early).

Failure = delinquency/possible administrative dissolution.
