When completing a workers' compensation report you should use gross pay—the total earnings before any deductions—because premiums are calculated on the full compensation amount an employee receives for work performed.

Why Gross Pay Is the Standard Metric
Workers' compensation insurance is designed to cover injuries that occur on the job, regardless of how an employee's paycheck is ultimately distributed. Insurers and state agencies base premium rates on the total compensation risk they assume, which is reflected in the employee's gross earnings. Using net pay would understate the true payroll exposure and could lead to underpayment of premiums, penalties, or coverage gaps.
How Gross Pay Is Determined
Gross pay includes all wages, salaries, overtime, bonuses, commissions, shift differentials, and any other remuneration earned before taxes, benefits, or other withholdings are taken out. For hourly workers, multiply the hourly rate by hours worked, then add any overtime premium (typically 1.5× the regular rate) and applicable bonuses. For salaried staff, use the annual salary divided by the reporting period, plus any supplemental earnings.
When Net Pay Might Appear in Reports
Some internal HR dashboards or payroll summaries display net pay because it reflects the amount employees actually receive. However, those figures are meant for budgeting and employee communication, not for workers' compensation calculations. If a report explicitly asks for "net compensation" you must verify the request with the insurer or regulator, but the default expectation remains gross pay.
Impact on Premium Calculations
Premiums are usually expressed as a rate per $100 of payroll. For example, a rate of $1.25 per $100 of gross payroll means a company with $500,000 in gross wages will owe $6,250 in premiums. Using net pay would lower the payroll base, artificially reducing the premium and exposing the employer to potential audit adjustments and fines.
Common Payroll Deductions Not Included in Gross Pay
- Federal, state, and local income taxes
- Social Security and Medicare taxes (FICA)
- Health, dental, and vision insurance premiums
- Retirement contributions (401(k), pension)
- Garnishments or wage attachments
These deductions are subtracted only after the gross amount has been reported for workers' compensation purposes.
Special Cases and Exceptions
Some jurisdictions allow certain types of compensation to be excluded from the payroll base, such as reimbursements for travel expenses or per‑diem allowances that are not tied to work performed. Always consult the specific state's workers' compensation handbook to confirm which items are exempt.
Quick Reference Table
| Component | Included in Gross Pay? | Reason |
|---|---|---|
| Base salary/wages | Yes | Core compensation subject to injury risk |
| Overtime | Yes | Additional work increases exposure |
| Bonuses/commissions | Yes | Earned compensation counts |
| Health insurance premiums | No | Deduction after earnings |
| Tax withholdings | No | Not part of earned wage |
| Travel reimbursements | Often No | Typically non‑wage expense |
Ensuring Accurate Reporting
1. Pull payroll data directly from the payroll system to avoid manual errors.2. Verify that the reporting period matches the insurer's required timeframe (monthly, quarterly, or annually).3. Cross‑check the total gross payroll figure against the sum of individual employee reports.4. Keep documentation of any excluded items in case of an audit.
Bottom Line
For workers' compensation reporting, always use gross pay unless a specific exemption is documented by the governing authority. Gross pay reflects the true payroll exposure, ensures correct premium calculation, and keeps you compliant with state regulations.
