Workers' Comp Payroll Audit

How Audits Work and How a PEO Eliminates the Surprise

Traditional workers comp policies are based on estimated payroll, which means you get a year end audit to true up the difference. That audit can produce a large unexpected bill. PEOs solve this with pay-as-you-go workers comp, which ties your premium to actual payroll each cycle and eliminates the audit surprise.

What Drives Your Cost

Key Workers Comp Factors

Estimated Payroll

Traditional policies are based on estimated annual payroll. If your actual payroll is higher, you owe more at audit. If lower, you get a refund.

Audit True Up

The year end audit compares your estimated to actual payroll. A large difference can produce a big bill or a big refund.

Class Code Verification

The audit also verifies your class codes. If employees were in the wrong code, your premium is adjusted, sometimes significantly.

Pay-As-You-Go

PEOs use pay-as-you-go billing, which ties your premium to actual payroll each cycle. No estimate means no audit surprise.

Subcontractor Audit

If you use subcontractors without certificates of insurance, the audit may charge you for their payroll as if they were your employees.

Audit Prevention

Accurate payroll reporting and class code assignment throughout the year prevents audit adjustments and surprises.

How Audits Work

How Traditional Workers Comp Payroll Audits Work

Traditional workers comp policies are based on your estimated annual payroll. You pay premium throughout the year based on that estimate. At the end of the year, the carrier audits your actual payroll. If your actual payroll was higher than estimated, you owe the difference. If it was lower, you get a refund. The audit also verifies your class codes. If employees were in the wrong code, your premium is adjusted.

  • Traditional policies are based on estimated annual payroll
  • You pay premium based on the estimate all year
  • At year end, the carrier audits your actual payroll
  • Higher actual payroll means you owe more at audit
  • Lower actual payroll means you get a refund
  • The audit also verifies your class code assignments
The Problem

Why Workers Comp Audits Create Cash Flow Shocks

The problem with traditional audits is the surprise. If your payroll was higher than estimated, you can get a large bill at year end that you were not expecting. For businesses with growing payrolls or seasonal fluctuations, this can be a significant cash flow shock. Subcontractor audits are even worse. If you used subs without certificates of insurance, the audit may charge you for their payroll as if they were your employees, which can double your premium.

The PEO Solution

How a PEO Eliminates the Audit Surprise

PEOs solve the audit problem with pay-as-you-go workers comp. Instead of estimating your annual payroll, the PEO ties your premium to your actual payroll each pay cycle. You pay exactly what you owe, when you owe it. No estimate means no year end audit true up. No surprise bill. Your workers comp cost tracks your actual payroll in real time, which makes budgeting predictable and eliminates the cash flow shock of a traditional audit.

FAQ

Payroll Audit FAQ

What is a workers comp payroll audit?

A workers comp payroll audit is a year end review by your carrier that compares your estimated annual payroll to your actual payroll. If your actual payroll was higher, you owe the difference. If lower, you get a refund. The audit also verifies your class code assignments.

How does a PEO eliminate the workers comp audit?

PEOs use pay-as-you-go workers comp, which ties your premium to your actual payroll each pay cycle instead of an annual estimate. Because you pay based on actual payroll throughout the year, there is no estimate to true up at year end and no audit surprise.

Can a workers comp audit produce a large bill?

Yes. If your actual payroll was significantly higher than estimated, or if subcontractors were not properly documented, the audit can produce a large unexpected bill. Growing businesses and seasonal businesses are most at risk for audit surprises.

What happens if my class codes are wrong during an audit?

If the audit finds employees in the wrong class code, your premium is adjusted. If they were in a higher rated code than they should have been, you get a refund. If they were in a lower rated code, you owe more. Accurate class code assignment throughout the year prevents audit adjustments.
