Workers’ Compensation Insurance Requirements in Kentucky
Kentucky treats missing workers’ comp coverage as a criminal matter, not just a fine. For roofers, electricians, and plumbers running crews across the state, a single uninsured employee — even part-time — is enough to trigger the requirement and put an owner at risk of felony charges if they skip it.
Kentucky Workers’ Compensation Legal Requirements
Under KRS 342.340, every Kentucky employer with one or more employees — full-time, part-time, or otherwise — must carry workers’ compensation insurance, and this applies fully to construction trades like roofing, electrical, and plumbing.
- Threshold: coverage is required the moment an employer has one or more employees, including part-time and seasonal workers
- Sole proprietors can exclude themselves from coverage in writing, but must still cover any employee they hire
- Penalties: operating without required coverage is a Class D felony under KRS 342.990, plus civil fines of $100–$1,000 per employee per day
- Construction-specific: applies to general contractors, electrical contractors, plumbers, HVAC companies, and roofers with no trade-specific exemption
How Kentucky’s Workers’ Comp System Works
System type: Private Carrier Market
Kentucky is a private-carrier state — coverage is purchased from private insurance companies, not a state-administered monopoly fund. Per the Oregon DCBS 2024 Workers’ Compensation Premium Rate Ranking Study, Kentucky ranks 41st of 51 jurisdictions with an index rate at just 70% of the national median, making it one of the more affordable states for workers’ comp nationally.
How Kentucky’s Rates Compare by Trade
| Trade (NCCI Class Code) | National Rank (of 51) | Rate per $100 of Payroll |
|---|---|---|
| Roofing (Class 5551) | 31st of 51 | $8.31 |
| Electrical Wiring (Class 5190) | 41st of 51 | $1.73 |
| Plumbing NOC (Class 5183) | 44th of 51 | $1.59 |

Filing a Workers’ Comp Claim in Kentucky
Injured employees report the injury to their employer, who notifies their insurance carrier and the Kentucky Department of Workers’ Claims. Disputed claims proceed through an Administrative Law Judge at the Kentucky Education and Labor Cabinet rather than through civil court.
Penalties for Non-Compliance
Operating without required coverage in Kentucky is a Class D felony under KRS 342.990, with civil fines of $100 to $1,000 per employee for every day of noncompliance — each day counts as a separate offense, and an uninsured employer also loses the exclusive-remedy protection, exposing them to a direct lawsuit for pain, suffering, and punitive damages.

How Much Does Workers’ Comp Insurance Cost in Kentucky?
Kentucky’s overall workers’ comp costs run well below the national median, but roofing still carries a significantly higher base rate than electrical or plumbing due to fall risk.
| Trade | Estimated Cost per $100 Payroll | What Drives It |
|---|---|---|
| Roofing | $8.31 (per the Oregon study’s Class 5551 rate) | Height and fall exposure keep roofing the costliest of the three trades |
| Electrical | $1.73 (per the Oregon study’s Class 5190 rate) | Lower claim severity keeps electrical among Kentucky’s more affordable trade classes |
| Plumbing | $1.59 (per the Oregon study’s Class 5183 rate) | Kentucky plumbing ranks near the bottom nationally for cost, reflecting a favorable claims environment |
What Moves the Price Up or Down
- Whether the owner has excluded themselves from coverage in writing (reduces payroll base used for premium)
- Experience modification factor built from the contractor’s claims history
- Felony-level penalty exposure makes continuous, uninterrupted coverage critical — a lapse is costlier than the premium itself
- Payroll size and mix of trade class codes across a multi-trade crew
Rates above are drawn from the Oregon DCBS 2024 Workers’ Compensation Premium Rate Ranking Study and represent national benchmark comparisons, not a binding quote. Actual premium depends on your experience modification factor, claims history, and payroll — get a personalized quote from Trade Safe.
Frequently Asked Questions
How many employees before I need workers’ comp in Kentucky?
Just one. Under KRS 342.340, any employer with one or more employees — including part-time workers — must carry workers’ compensation insurance.
Can a Kentucky sole proprietor opt out of workers’ comp?
A sole proprietor can exclude themselves personally in writing, but the moment they hire even one employee, coverage becomes mandatory for that worker regardless of the owner’s own exclusion.
What’s the penalty for skipping workers’ comp in Kentucky?
It’s a Class D felony under KRS 342.990, plus civil fines of $100 to $1,000 per employee for every day the business goes uninsured — each day is a separate violation.
What happens if my uninsured employee gets hurt on the job in Kentucky?
The employer loses the exclusive-remedy protection that normally shields employers from lawsuits, meaning the injured worker can sue directly for medical costs, lost wages, pain and suffering, and punitive damages.
Workers’ compensation requirements and penalties can change; verify current rules with the Kentucky Department of Workers’ Claims, Education and Labor Cabinet.
