Does Workers Compensation Get Charged on Overtime?

How Workers Comp Premiums Are Calculated

Workers compensation premiums are based on payroll, and overtime is typically included in that payroll figure. The premium is calculated by multiplying the payroll by a rate tied to the job classification and the employer's experience modification factor. Because overtime wages increase the total payroll, they can raise the premium charged for the policy period.

When Overtime Is Included and When It Is Not

In most states, overtime wages are counted in workers comp payroll for premium purposes. However, some policies and rating bureaus allow an overtime exclusion if the overtime is genuinely sporadic and documented. If a business regularly relies on overtime as part of its staffing model, the payroll is almost always charged at the full rate. The key variable is the insurance carrier's rules and the state rating bureau's guidelines for the class code assigned.

The Role of Job Classification Codes

Every employee is assigned a class code that reflects the risk level of their work. A laborer in a high-risk classification will have a higher rate than an office worker. Overtime wages for the high-risk laborer are multiplied by that higher rate, so the premium impact is amplified. Misclassifying workers or failing to report overtime accurately can lead to audit adjustments and additional charges at renewal.

How to Manage the Cost

Employers can reduce the overtime impact by keeping detailed payroll records that separate regular and overtime hours. Some policies offer a payroll reporting option that lets you adjust the premium mid-term if overtime is lower than estimated. Working with an agent who understands the classification system and can negotiate an overtime exclusion endorsement, where permitted, can also lower costs.

• Overtime is usually included in workers comp payroll.
• Premiums rise because the total payroll base increases.
• High-risk class codes amplify the cost impact.
• Some states allow an overtime exclusion endorsement.
• Accurate reporting prevents audit penalties.

Practical Example

Assume a construction worker earns $25 per hour and works 10 hours of overtime at $37.50. The regular payroll for that pay period is $1,000, and the overtime adds $375, bringing the total to $1,375. If the class code rate is $1.50 per $100 of payroll, the premium for that period increases from $15 to $20.63. The overtime wages directly raise the premium because the payroll base used for the calculation is larger.

Key Takeaway

Workers compensation does get charged on overtime in the majority of cases because the premium is tied to total payroll. The exact treatment depends on the policy language, the state rating rules, and whether an overtime exclusion endorsement applies. Keeping clean payroll records and reviewing the policy with a knowledgeable agent are the most reliable ways to manage the cost.
