Premium Audit

Settling Up

In the workers’ compensation industry, policyholder premiums get calculated not once, but twice. The first calculation is an estimate based on the business operations, payroll and job classifications in effect when you applied for coverage. The second calculation, performed at the end of the policy year, is based on an audit of these performance measures. If your actual performance differs from what was estimated, your business may receive a refund or be billed additional premium. 

Types of Audits

The following information gives you guidance on the premium audit process, tips for preparing and more.


Self-audit questionnaires are mailed to you to complete and return with the appropriate requested information. The questionnaires are sent the day your policy ends and allow you thirty days to complete and return.

Good Record Keeping Tips

Overtime Earnings

The most common way to reduce your insurance cost is to differentiate overtime earnings in your records to separate straight time and premium time. For instance, the half-time portion of ‘time and one-half’ for overtime wages is not included in calculating your premium.

Tip Wages

Employee tip wages will not be included when they are separated from your employee’s regular wages.

Correct classification(s)

Use correct classification(s) to describe your business, as sometimes there are lower cost classifications available to you. Determining correct business classifications can be complicated and our premium audit professionals can help you understand this process.
