Washington compliance best-practice documentation

I used the available research tools to collect authoritative and up-to-date information (through Jan 3, 2026) about Washington state compliance best practices for LLCs and small businesses. Sources included the Washington Secretary of State, Department of Revenue (Business Licensing Service), Department of Labor & Industries, Employment Security Department (Paid Family & Medical Leave), WA Cares Fund, FinCEN (BOI filing), business.wa.gov, and local-government resources (MRSC).

I extracted key deadlines, fees, filing links, employer obligations, penalties, and recommended documentation/templates. Summary of findings and citations provided below.
