Delaware Workers Compensation Guide

Workers Compensation Requirements in Delaware

Delaware requires workers' compensation for all employers with one or more employees. Coverage is obtained through private insurers or self-insurance. Delaware's Industrial Accident Board handles workers' comp disputes. Delaware has a relatively small workers' comp market given its small population.

Workers Comp Rates in Delaware

Workers compensation premiums in Delaware are calculated based on payroll, job classification (NCCI or state classification codes), and the employer's experience modification factor. The average rate of approximately $1.78 per $100 of payroll is a statewide blended average — actual rates vary significantly by job classification. A clerical office worker might pay $0.20-$0.40 per $100, while a roofing contractor might pay $15-$25 per $100.

For example, an employer with $1 million in payroll at the average rate of $1.78 per $100 would pay approximately $17,800 annually before experience modification adjustments. Employers with better-than-average loss experience (experience mod below 1.0) pay less; those with worse experience pay more.

How Workers Comp Premiums Are Calculated in Delaware

Workers compensation premiums in Delaware follow this basic formula: (Payroll / 100) × Classification Rate × Experience Modification Factor = Premium. The experience modification factor (EMR or X-Mod) compares your actual loss experience to the expected loss experience for your industry. An EMR of 1.0 is average; below 1.0 means better-than-average safety record (lower premiums); above 1.0 means worse-than-average (higher premiums).

Job classification codes are assigned based on the type of work employees perform. Accurate classification is critical — misclassifying employees into lower-risk categories can result in premium audits and significant back-premium assessments. An employer with employees in multiple classifications must track payroll by class code throughout the year.

How to Reduce Workers Comp Costs in Delaware

Delaware's small market means fewer insurer options — working with a broker who specializes in Delaware workers' comp is helpful. Safety programs and return-to-work policies reduce costs. Proper worker classification is important to ensure correct premium calculation.

• Implement a formal workplace safety program — documented safety training reduces injury frequency and improves experience modification over time.
• Develop a return-to-work program — getting injured workers back on modified duty reduces temporary disability claim duration and cost.
• Report all injuries promptly — early reporting enables timely medical treatment and claims management, reducing claim severity.
• Review job classifications annually — ensure employees are classified in the correct (not simply the lowest-cost) classification code.
• Work with a loss control specialist — many insurers offer free safety consultation services that identify hazard reduction opportunities.
