Workers’ Compensation Insurance Requirements in Delaware
Delaware’s threshold is simple — one employee triggers the mandate — but its penalty structure for skipping coverage is unusually severe, tying fines to unpaid premium amounts rather than a flat daily rate. HVAC and excavation crews in particular should note the state’s above-average rates for those trades.
Delaware Workers’ Compensation Legal Requirements
Under 19 Del. C. § 2306, any employer with one or more employees must secure workers’ compensation coverage; sole proprietors without employees are not required to cover themselves but may opt in.
- Coverage is required starting with the first employee hired, with no exemption based on hours worked
- Sole proprietors and partners with no employees can choose to opt in for their own coverage but aren’t required to
- Noncompliance penalties can reach up to three times the premium that would have been owed, plus $10 per employee per day
- The state can seek a court injunction shutting down an uninsured business until coverage is obtained
How Delaware’s Workers’ Comp System Works
System type: Private Carrier Market
Delaware is a private-carrier, competitive state where employers buy coverage from licensed insurers. In the Oregon DCBS 2024 study, Delaware ranked 32nd of 51 jurisdictions overall, with an index rate at 89% of the national median, placing it slightly below the national average for overall premium burden, though certain trades like HVAC run notably higher.

Filing a Workers’ Comp Claim in Delaware
Injured workers should notify their employer promptly, and the employer’s carrier files the claim with the Delaware Department of Labor’s Office of Workers’ Compensation. Delaware uses a first-report-of-injury process and, for disputed claims, a hearing process before the Industrial Accident Board.
Penalties for Non-Compliance
Delaware can penalize uninsured employers up to three times the premium they would have paid, plus $10 per employee per day of the violation, and can pursue a court injunction to shut the business down under 19 Del. C. § 2320.

How Much Does Workers’ Comp Insurance Cost in Delaware?
Delaware’s rates run below the national median for most trades, including roofing and electrical, but certain trades like HVAC carry a disproportionately high rate. Plumbing sits close to the middle of the national range.
| Trade | Estimated Cost per $100 Payroll | What Drives It |
|---|---|---|
| Roofing | $2.87 (per the Oregon study’s Class 5551 rate) | Delaware’s roofing rate ranks near the bottom nationally (44th of 51), among the lowest-cost states for this trade |
| Electrical | $2.09 (Class 5190) | Below-median rate reflecting comparatively lower claim frequency for the trade statewide |
| Plumbing | $2.69 (Class 5183) | Mid-range nationally, in line with Delaware’s overall below-average premium burden |
What Moves the Price Up or Down
- Experience modification factor — a clean claims record can meaningfully lower Delaware premiums
- Payroll size — premium scales directly with total payroll per $100
- Claims history — repeat claims raise future premium calculations
- Trade classification — Delaware’s rate varies widely by trade, with HVAC a notable outlier compared to roofing and electrical
