Washington compliance for SAAS companies

Summary of research and key findings: I researched Washington-specific compliance requirements that SaaS companies (US business owners and LLC founders) need to know. I focused on tax compliance (sales tax, Business & Occupation tax, nexus and registration), corporate/LLC filings (formation, foreign qualification, annual reports, UBI/business license), data privacy and breach reporting, cybersecurity/sector-specific privacy (health data), and practical next steps.

Major findings and practical guidance: 1) SaaS taxability in Washington - Washington treats most SaaS/remote access prewritten software (often called RAS or digital automated services) as taxable. Businesses with nexus must collect retail sales tax on SaaS and also account for Washington’s Business & Occupation (B&O) tax on gross receipts. (See DOR/RCW guidance and state tax summaries.) - Economic nexus threshold: Washington’s economic nexus is triggered at $100,000 in annual sales sourced to Washington (current or prior year).

If you meet nexus, you must register with the Department of Revenue, collect sales tax, and file returns. - Sales tax base and local rates: State base sales tax 6.5% plus local rates (combined rates can reach ~10.6%).

B&O tax applies under applicable activity classification (services/other activities); consult DOR for exact classification and rates. Practical steps: Determine product classification (prewritten vs. custom software), track Washington-sourced sales monthly, register via My DOR eServices, collect sales tax where required, and file B&O and sales tax returns on the assigned schedule. 2) Business registration, licenses, and corporate filings - Unified Business Identifier (UBI) / Business License: Use the Business Licensing Application (Business Licensing Service / DOR) to get a UBI and applicable state/city endorsements.

You need a license if you collect sales tax, hire employees, or have ≥$12,000 gross income, among other triggers. - Secretary of State filings: Form/maintain LLCs through the WA Secretary of State Corporations Division.

Domestic and foreign LLC filings have fees (e.g., formation/foreign registration $180). Annual reports must be filed to remain in good standing; for foreign LLCs Northwest notes the annual report costs and is due the last day of the month you registered in WA (confirm current fee/penalty on SOS site).

Practical steps: If you form in WA or do business in WA, file formation or foreign registration with the SOS (appoint a registered agent), register for a UBI and DOR accounts, and calendar annual report due dates for SOS filings and DOR renewals. 3) Data breach notification and privacy - Washington has two breach-notification regimes: RCW 19.255 (private businesses) and RCW 42.56.590 (state/local agencies).

Washington requires notice to affected individuals “in the most expedient time possible” and within 30 days after discovery; if 500+ residents are affected, the Attorney General must also be notified. The state’s definition of "personal information" is broad.

Practical steps: Maintain an incident response plan; encrypt data where feasible; prepare breach notice templates; track discovery date; notify affected WA residents and the AGO when thresholds are met; retain counsel for notifications and mitigation. 4) Sector-specific privacy: health data - Washington’s My Health My Data Act (RCW 19.373) expands protections for health-related data beyond HIPAA-covered entities (gives rights like access, deletion, consent withdrawal).

This affects SaaS providers that collect health or wellness data from Washington residents even if not a traditional healthcare provider. Practical steps: If your SaaS handles health-related or wellness data for WA residents, review RCW 19.373 requirements, update privacy policies, implement data subject request procedures, and consider additional security controls and disclosures. 5) Cybersecurity and consumer protection exposure - Washington enforces consumer protection laws (e.g., the Washington Consumer Protection Act RCW 19.86) against unfair or deceptive practices, including false data-security claims.

Criminal computer-trespass statutes and other laws also apply. State guidance recommends encryption, written breach policies, incident response, and adopting frameworks (NIST/CIS) to reduce regulatory risk.

Practical steps: Publish accurate security practices, adopt NIST or equivalent frameworks, perform annual risk assessments, encrypt data in transit and at rest, and maintain breach response procedures. 6) Employer obligations if you hire in WA - Hiring Washington employees creates additional registration and compliance obligations (register with DOR for payroll withholding, Employment Security Department for unemployment, L&I for workers’ compensation, and comply with WA Paid Family & Medical Leave and state wage/hour requirements). (Recommend registration with ESD, L&I and PFML; confirm exact registration steps on each agency site.) Actionable checklist for a SaaS company selling to Washington customers or operating in Washington: - Tax & registration - Determine whether your product is taxable (prewritten SaaS vs. custom software). - Monitor Washington-sourced revenue; if ≥ $100,000, register with WA DOR and begin collecting/filing sales tax and B&O tax. - Corporate compliance - If forming or qualifying in WA, file formation or foreign registration with SOS (fees apply), appoint a registered agent, and calendar annual report filings (last day of the month you registered; confirm fees on SOS).

Maintain good standing. - Privacy/cybersecurity - Implement strong security controls, encryption, logging, incident response playbook, and breach-notification templates keyed to WA rules (30-day deadline; notify AGO if 500+ residents).

Update privacy policy and DSR procedures for Washington (My Health My Data for health data). - Hiring/employment - Register for payroll withholding, unemployment, and workers’ comp before hiring WA employees.

Comply with WA PFML and wage laws. - Documentation & audits - Keep detailed transactional records, exemption certificates, and tax filings; maintain evidence of consent, data retention, and DSR handling; perform periodic compliance assessments.

Recommended next research/verification steps (I can fetch these if you want me to): - Pull authoritative DOR pages on digital products, B&O tax rates and filing frequencies, and the precise RCW citations on SaaS taxability (e.g., RCW 82.04.257) and DOR guidance on Multiple Points of Use (MPU) exemptions. - Pull the WA Secretary of State pages showing the exact annual report fees and due date guidance and the technical steps for foreign registration and annual report filing. - Pull the full text of RCW 19.255, RCW 42.56.590 (breach notification), and RCW 19.373 (My Health My Data) for verbatim compliance obligations. - Pull Employment Security Department, L&I, and WA PFML employer registration pages.
