Understanding Washington Workers' Compensation Rules for Employee Bonuses

What Washington Workers' Compensation Covers Regarding Bonuses

In Washington, workers' compensation is designed to replace lost wages and cover medical costs when an employee is injured on the job. Bonuses—whether performance‑based, seasonal, or discretionary—are considered part of an employee's regular earnings only if they are earned before the injury occurs and are tied to work performed. This article explains when bonuses are covered, how they affect benefit calculations, and what employers must do to stay compliant.

Key Definitions

Before diving into the rules, clarify the terminology used in Washington's workers' compensation system.

• Average Weekly Wage (AWW): The baseline wage used to calculate wage‑replacement benefits.
• Earned Bonus: A bonus that is vested or payable based on work already performed before the injury date.
• Unearned Bonus: A bonus contingent on future performance or milestones that have not yet been met.
• Discretionary Bonus: A bonus given at the employer's sole discretion, not guaranteed by contract.

When Bonuses Are Included in Wage‑Replacement Benefits

Washington law (RCW 51.16) requires the AWW to reflect all compensation the employee would have earned but for the injury. The following bonuses are typically included:

• Performance bonuses earned before the injury date.
• Year‑end or holiday bonuses that are already calculated and payable.
• Commission payments that are earned on sales completed prior to injury.

These amounts are added to the regular wage base when the Workers' Compensation Appeals Board (WCAB) determines the AWW.

Bonuses That Are Generally Excluded

Not all bonuses count toward workers' compensation benefits. Exclusions include:

• Bonuses contingent on future sales, production, or performance.
• Discretionary awards that have not been formally promised or documented.
• Sign‑on bonuses that are paid after the injury and are not tied to work performed before the injury.

Calculating the Adjusted Average Weekly Wage

When a bonus is deemed earned, the WCAB adds its prorated value to the employee's regular earnings. The formula is:

The resulting Adjusted AWW determines the weekly wage‑replacement benefit, which is currently 70% of the AWW, subject to statutory minimums and maximums.

Employer Responsibilities

Employers in Washington must:

• Maintain accurate payroll records that clearly separate regular wages from bonuses.
• Document the terms of any bonus program, including eligibility dates and vesting schedules.
• Report earned bonuses to the Washington State Department of Labor & Industries (L&I) when filing a claim.
• Cooperate with the WCAB's wage‑verification process, providing pay stubs, bonus statements, and contracts.

Employee Actions and Rights

Injured workers should:

• Gather all bonus-related documentation (e.g., bonus agreements, award letters, recent pay stubs).
• Notify their employer promptly of the injury and request a copy of the wage‑calculation worksheet.
• If a dispute arises, request a hearing before the WCAB to argue that a bonus was earned and should be included.

Common Misconceptions

Many employees assume that any bonus they receive after an injury is automatically counted. In reality, only bonuses earned before the injury and that are not discretionary qualify. Conversely, some think bonuses are never counted; however, Washington law is explicit about incorporating earned bonuses into the AWW.

Practical Example

John works as a sales associate earning $1,000 weekly. He receives a $2,400 quarterly commission that is paid after each quarter's end. John is injured in week 10 of the quarter, before the commission is paid but after the sales that generated it are completed. Because the commission is earned based on work performed before the injury, the WCAB will add a prorated portion of the commission ($2,400 ÷ 12 weeks = $200 per week) to John's AWW, raising his weekly benefit from $700 (70% of $1,000) to $770 (70% of $1,100).
