Is Workers’ Comp Required in Washington?
Yes, workers’ compensation is required in Washington for all employers with one or more employees, whether full-time, part-time, or seasonal; coverage must be obtained from the Washington State Department of Labor and Industries (L&I) state fund or through certified self-insurance
Washington Workers’ Comp Requirements at a Glance
Here are the exact Washington workers compensation requirements every employer should know:
| Employees that trigger the mandate | 1 |
| Which workers count | The mandate applies from the first employee; all workers count toward the threshold including full-time, part-time, and seasonal employees; there is no minimum-hours or industry-specific threshold — one employee of any kind triggers the requirement |
| Who is exempt | Sole proprietors with no employees; partners and LLC members with management responsibility who have no additional employees; bona fide corporate officers who are also directors and shareholders, exercise substantial control in daily management, and whose primary duties do not include performing services subject to mandatory coverage (up to 8 officers in a non-public corporation per RCW 51.12.020); musicians and entertainers performing under a specific-engagement contract; licensed jockeys while preparing horses for or participating in race meets; for-hire vehicle operators and taxicab operators who own or lease the vehicle; volunteer law enforcement officers; and volunteers for private nonprofit charitable organizations or local governments |
| Owners & officers | Sole proprietors, partners, and LLC members with management responsibility are automatically excluded from mandatory coverage but may voluntarily elect coverage by filing written notice with L&I; bona fide corporate officers who are directors and shareholders exercising substantial control and not primarily performing manual labor may be excluded — up to 8 officers in a non-public corporation; excluded owners and officers can opt in at any time by notifying L&I |
| Penalty for going without | An employer who fails to secure coverage faces a penalty of up to 1000 or double the amount of premiums incurred before obtaining coverage, whichever is greater (RCW 51.48.010); if a worker is injured while uninsured the employer is liable for 50 to 100 percent of the cost of the claim plus the penalty; L&I may issue a stop-work order for construction contractors and electrical contractors (RCW 51.48.022) requiring a cash deposit or bond of 5000 or 1000 per covered worker, whichever is greater, to continue operating; violating a stop-work order carries a daily penalty of up to 1301 per day (inflation-adjusted effective July 1 2026); knowingly failing to secure coverage or making false reports is a gross misdemeanor or felony under RCW 51.48.020; general noncompliance penalties under Title 51 are inflation-adjusted every 3 years |
| Monopolistic state? | Yes — must buy from the state fund |
| State fund | Washington State Fund, administered by the Washington State Department of Labor and Industries (L&I); this is a monopolistic state fund — employers must purchase coverage through L&I unless they qualify for certified self-insurance |
How to Get Workers’ Comp Coverage in Washington
Employers must register for a workers’ compensation account with the Washington Department of Labor and Industries (L&I) through their state business license; L&I calculates premiums based on employee classification and hours worked; alternatively employers with 25000000 or more in assets may apply for certified self-insurance through L&I; there is no private carrier option and no assigned-risk pool because the state fund accepts all employers
What Workers’ Comp Covers in Washington
Workers’ compensation is a no-fault system: an injured employee gets benefits without having to prove the employer did anything wrong, and in exchange gives up the right to sue for most workplace injuries. A typical Washington policy pays for medical treatment tied to a work injury, part of the wages lost while the worker recovers, longer-term disability benefits if the injury is permanent, and death benefits to a family.
It also includes employers-liability coverage, which protects the business if an injury still leads to a lawsuit. That trade-off is the practical heart of the Washington workers compensation requirements: the coverage exists to keep one bad injury from sinking both the worker and the business.
Employees vs. Independent Contractors in Washington
The most common way owners get the Washington workers compensation requirements wrong is by assuming a worker is an “independent contractor” who does not count. State agencies look at how the work is actually controlled, not the label on a 1099. If Washington decides a contractor was really an employee, the business can owe back premiums and penalties as if coverage should have been in place all along.
When you are close to the employee threshold, confirm each worker’s status with your state board before you decide you are exempt.
Other Washington workers’-comp rules: Washington is one of only 4 monopolistic workers’ compensation states (along with North Dakota Ohio and Wyoming) where private insurers cannot write workers’ comp policies; Washington uses an hours-based premium system rather than a pure payroll-based system — employers report actual hours worked per risk classification and premiums are calculated per hour worked;
both employers and employees share the cost of premiums in Washington with the employer paying the accident fund portion and the employee paying the medical aid fund portion through payroll deduction; employers must report quarterly to L&I; construction contractors and electrical contractors face additional registration requirements under chapters 18.27 and 19.28 RCW and are subject to stop-work orders for noncompliance
Understanding Washington Workers Compensation Requirements
