Are Self‑Employed Workers Exempt from Workers' Compensation in Washington?

Answer in 90 Words

In Washington, self‑employed workers are not automatically exempt from workers' compensation. The state's Workers' Compensation Act applies to any business that employs workers, including independent contractors who are paid by a client and perform work for a single employer. Sole proprietors who hire others must also carry coverage. However, a sole proprietor who does not employ anyone and works exclusively for themselves can opt out, but must still comply with other insurance requirements for certain high‑risk activities.

What the Law Says

Key Statutory Provisions

Washington law defines a "worker" as anyone who performs work for an employer, regardless of the nature of the relationship. The law specifically excludes "independent contractors" who are not under the direct control of the hiring party. However, many independent contractors are treated as employees if they are effectively integrated into the client's business.

Exemption Criteria for Sole Proprietors

A sole proprietor who is the sole employee of their business and does not hire anyone can apply for an exemption. To qualify, the proprietor must:

• Operate under a single business entity.
• Not pay wages or salaries to anyone other than themselves.
• Maintain a written statement of their exemption request.

How to Determine Your Status

Are You an Employee or an Independent Contractor?

Use the IRS 20-factor test and Washington's own guidelines to assess whether you are truly independent. If you:

• Control how, when, and where the work is done.
• Supply your own tools and materials.
• Have the right to subcontract the work.
• Are paid per project, not hourly, and have no benefit package.

you likely qualify as an independent contractor and may be exempt if you don't hire others.

Do You Hire Others?

If you bring in subcontractors or employees, you become a "business" under the Workers' Compensation Act and must obtain coverage. Even a single employee triggers the requirement.

Practical Steps for Compliance

Obtaining Coverage

Washington offers two primary insurance options:

• Standard Workers' Compensation Policy – covers all employees.
• Self‑Insurance Program – available for larger employers with a proven risk management program.

Reporting and Filing

All employers must file a WS-1 form with the Washington State Department of Labor & Industries (L&I) within 30 days of hiring an employee. Failure to file can result in penalties.

Common Misconceptions

• "I'm a freelancer, so I'm exempt." – Only if you have no employees.
• "I work for one client, so I'm not an employee." – The nature of control matters, not the number of clients.
