Understanding Payroll for Workers' Compensation in New Jersey

Definition of payroll for workers' compensation

In New Jersey, payroll for workers' compensation includes all wages and compensation paid to employees that are subject to the state's workers' compensation insurance requirements. This comprises regular salaries, hourly wages, overtime, commissions, bonuses, and the cash value of most benefits.

Common components counted as payroll

The following items are typically included in the payroll calculation:

• Base salary or hourly wages
• Overtime pay
• Shift differentials
• Commissions and incentive payments
• Bonuses (performance, holiday, or discretionary)
• Paid sick leave and vacation when paid out at termination
• Cash value of employer‑provided benefits such as health insurance, disability coverage, and retirement contributions if they are taxable

Items generally excluded

Not all compensation is counted. Exclusions usually include:

• Employer contributions to non‑taxable retirement plans (e.g., 401(k) matching)
• Reimbursements for business expenses
• Workers' compensation benefits paid under the policy itself
• Non‑cash fringe benefits that are not taxable

How payroll affects premiums

Workers' compensation premiums are calculated by multiplying the employer's total payroll (as defined above) by the classification rate for each job category. Accurate payroll reporting ensures the correct premium is charged and helps avoid penalties.

Reporting and compliance

Employers must report payroll to the New Jersey Compensation Rating and Inspection Bureau (CRIB) annually, typically using the Employer's Report of Payroll (Form WC‑4). The report must reflect the total payroll for the preceding calendar year and be submitted by the deadline to maintain coverage.
