What Are New Jersey Workers' Compensation Rates?
In New Jersey, workers' compensation rates are the premiums employers pay to cover medical costs, wage replacement, and other benefits for employees who suffer job‑related injuries or illnesses. The rates are set annually by the New Jersey Department of Labor & Workforce Development (NJDOL) and vary by industry, job classification, and an employer's past claims history.

How Are Rates Determined?
New Jersey uses a formula that considers three main factors:
- Industry Classification (Industry Group): Each business is assigned to a specific industry group (e.g., construction, manufacturing, retail). Some industries have higher injury rates, leading to higher premiums.
- Job Classification (Job Group): Within each industry, specific job roles are grouped. For example, a heavy construction worker and a light office worker will fall into different job groups with distinct rate tables.
- Claims History (Experience Modification Factor): Employers with a history of frequent or costly claims receive a higher modifier, while those with a clean record receive a discount.
The formula produces a rate per 1,000 hours worked, expressed in dollars per employee per year. Employers report the number of hours worked by each employee to calculate the total premium.
Typical Rate Ranges by Industry
Rates vary widely. Below is a snapshot of average annual premiums per employee for some common industry groups in New Jersey. The figures are approximate and can shift year to year.
| Industry Group | Average Annual Premium (USD) | Source Type |
|---|---|---|
| Construction (heavy) | 12,500 – 15,000 | State Rate Table |
| Manufacturing | 8,000 – 10,000 | State Rate Table |
| Retail | 3,500 – 5,000 | State Rate Table |
| Information Technology | 4,000 – 6,000 | State Rate Table |
| Healthcare (nurses) | 9,000 – 11,000 | State Rate Table |
Experience Modification Factor (EMF) Explained
The EMF is a decimal multiplier applied to the base rate. An EMF of 1.00 means the employer's experience is average. Values below 1.00 discount the premium; values above 1.00 increase it.
Example:
Base rate for a manufacturing company = $9,000 per employee per year.EMF = 1.20 (20% above average claim cost).Premium = $9,000 × 1.20 = $10,800 per employee.
How Employers Can Improve Their EMF
1. Implement robust safety programs.2. Provide regular training on hazard recognition.3. Conduct thorough incident investigations.4. Encourage a culture of reporting near‑misses.5. Maintain accurate records and promptly file claims.
Reporting and Payment Process
Employers must submit an annual rate application to the NJDOL, including:
- Number of employees and hours worked per job group.
- Claims history for the past 3–5 years.
- Business size and payroll details.
After review, the NJDOL publishes the rate schedule. Employers then pay premiums monthly or quarterly, depending on their payroll size.
Implications for Employees
Employees who suffer a workplace injury receive:
- Medical treatment covered by the employer's insurance carrier.
- Temporary total disability (TTD) benefits: 50% of average weekly wage, up to a statutory cap.
- Permanent partial disability (PPD) benefits if a lasting impairment remains.
- Rehabilitation and vocational services when appropriate.
The state's workers' comp system is designed to provide quick, guaranteed benefits, regardless of fault.
