Premium Audit

In today’s competitive marketplace, it is important to accurately account for all of your expenses.  A.I.M. Mutual’s Premium Audit services can help you to better project and account for your workers’ compensation costs.  A payroll audit is the determination and reporting of actual exposures through an examination of your operations, records and books of account.  These exposures are then used in the pricing of your insurance.  Audits are performed after the expiration or cancellation of a workers’ compensation policy or at specified intervals.




Total Remuneration



Workers' compensation insurance premium is primarily based upon gross payroll, which is defined as total remuneration for services performed by an employee. Total remuneration means money or substitutes for money and includes:

  • Wages, Commissions, Bonuses
  • Overtime, Holiday, Vacation, and Sick Pay
  • 401(k) and Section 125 Employee Contributions
  • Income Tax Deferred Pay
  • Profit Sharing Plans
  • Payment for Piece Work
  • Value of Board & Lodging
  • Tool Allowances
  • Store Certificates
  • Other Dollar Substitues

Total Remuneration Exclusions:

  • Tips and Other Gratuities
  • Payments by an employer to Group Insurance or Group Pension Plans (other than payments for the Federal Social Security Act)
  • Value of Special Rewards for individual invention or discovery
  • Dismissal or Severance Payments (except for time worked or accrued vacation)
  • Sick pay paid to an employee by a third party such as an insured’s group insurance carrier which is paying disability income benefits to a disabled employee
  • Employer provided perquisites such as an automobile, airplane flight, incentive vacation (contest winner), discount on property or services, club memberships, tickets to entertainment events, or executive officer remuneration above each states published maximum.








In Massachusetts, New Hampshire and Connecticut as in most states, the premium portion of overtime pay (the amount paid in excess of straight time pay) may be deducted from gross payroll totals. In order to benefit from this provision, overtime must be shown separately by employee and summarized by class of work group.


Division of Payroll



Your policy may carry one or more classifications of payroll based on your operation or business. An in-depth guide for Massachusetts’s classifications is available at the Workers' Compensation Rating and Inspection Bureau of Massachusetts website- Select Class Code Lookup or Manuals/MA Master Alphabetical under Products and Services.

Segmentation or division of an individual’s payroll to more than one classification is not permitted. If an employee interchanges between operations subject to more than one classification, the entire payroll of such employee shall be assigned to the highest rated classification representing any part of his/her work. This assignment applies irrespective of the actual time devoted to the classes of work. Exceptions do apply to employees involved with construction or erection operations; your premium auditor will be glad to discuss those exceptions with you.


Hiring of Uninsured Independent Contractors or Sub-Contractors



In Massachusetts, as a “General Employer,” you may potentially be responsible for injures to an employee of an uninsured contractor whom you have hired. This may be particularly applicable if the injury occurs on your premises and the contract is to perform work that may be deemed to be a part of, or a process of, your trade or business. “Premises” may include the public highways if the contract requires or necessitates the use of them.

In certain circumstances, you can reduce your liability for injuries to others working on your premises under contract (written or oral) by securing a current Certificate of Workers' Compensation Insurance from each contractor you employ (see Request a Certificate). If Certificates of Workers' Compensation Insurance for subcontractors are not available at the time of audit, the subcontractor’s exposure may be included in the pricing of your insurance.

Please contact us for more in-depth management procedures in the use of Certificates of Insurance to limit your premium liability.
