Delaware employers must reference the state's workers' compensation rate chart to determine premium costs for each employee classification. The chart lists a numeric class code, the corresponding job description, and the base rate per $100 of payroll, which is then adjusted by experience modifiers and optional coverage selections. Below is an overview of the key components, how rates are applied, and practical steps for accurate reporting.

What the Rate Chart Represents
The Delaware Workers' Compensation Rate Chart is published annually by the Delaware Department of Labor, Office of Workers' Compensation. It translates the risk associated with a job into a dollar amount that insurers charge per $100 of payroll. Higher‑risk occupations (e.g., construction laborers) have higher rates than low‑risk roles (e.g., clerical staff).
Core Elements of the Chart
Each line in the chart contains three essential fields:
- Class Code: A four‑digit identifier used on the employer's payroll report.
- Job Description: A brief description of the duties covered by the code.
- Base Rate: The premium amount (in dollars) per $100 of payroll before adjustments.
Sample Rate Table (2024)
| Class Code | Job Description | Base Rate ($/100 payroll) |
|---|---|---|
| 0010 | Executive/Administrative | 0.85 |
| 0100 | Construction – General Labor | 6.20 |
| 0200 | Manufacturing – Assembly | 3.45 |
| 0300 | Retail – Sales Associates | 1.10 |
| 0400 | Healthcare – Nursing | 2.80 |
Rates are illustrative; the official chart contains over 200 classifications and updates each year.
How Employers Calculate Premiums
Premium calculation follows a three‑step formula:
Example: A retailer with $250,000 payroll under class 0300 (rate 1.10) and an EMF of 0.95 would pay (250,000 ÷ 100) × 1.10 × 0.95 = $2,587.50.
Experience Modification Factor (EMF)
The EMF reflects an employer's safety record compared to industry averages. An EMF < 1.0 reduces premiums, while > 1.0 increases them. The factor is recalculated annually based on reported claims and is applied uniformly across all classifications.
Key Dates and Filing Requirements
Delaware law mandates:
- Annual filing of the Workers' Compensation Payroll Report by March 1.
- Payment of premiums by the due date on the notice from the insurer (typically within 30 days of report acceptance).
- Submission of any claim adjustments within 30 days of a workplace injury.
Common Mistakes to Avoid
- Misclassifying employees—using a higher‑risk code can inflate costs, while a lower‑risk code may trigger penalties.
- Failing to update payroll totals when staff move between classifications.
- Neglecting the EMF impact; reviewing the factor each year can reveal savings opportunities.
Resources for Accurate Reporting
