Handling a Workers’ Compensation audit in New York is mostly about preparation, documentation, and understanding how insurers calculate premiums. These audits are common and typically happen after the policy period ends to verify payroll, employee classifications, and risk exposure.

Below is a practical step-by-step guide to manage a Workers’ Comp audit properly—especially useful for business owners, accountants, and tax professionals.

1. Understand Why the Audit Happens

Workers’ compensation premiums are usually based on estimated payroll when the policy starts. The audit verifies the actual payroll and employee classifications for that policy period. (dimovaudit.com)

The auditor will check:

• Total payroll paid to employees
• Job classifications (risk categories)
• Overtime pay
• Independent contractors vs employees
• Subcontractor insurance certificates
• Business operations

If payroll was higher than estimated, you may owe additional premium. If it was lower, you may receive a credit. (Lovell Safety Management)

Step-by-Step: How to Prepare for the Audit

Step 1: Gather Required Documents

The auditor will typically request documentation such as:

Payroll records

• Payroll reports for the policy period
• Quarterly payroll tax reports (Form 941)
• Annual tax filings (W-2, W-3, 1099)

Accounting records

• General ledger
• Profit & Loss statements
• Cash disbursement journals

Employee information

• Job descriptions
• Employee classification codes
• Time sheets or time tracking reports

Subcontractor documents

• Certificates of Workers’ Compensation insurance
• Contracts with subcontractors

If you cannot prove a subcontractor had their own workers’ comp coverage, the insurer may add those payments to your payroll and charge additional premium. (LPL Risk Management)

Step 2: Review Employee Classifications

Workers’ comp premiums are based heavily on job classification codes (risk level of the work).

Common issues auditors find:

• Office workers classified as field workers
• Construction workers misclassified
• Employees performing multiple roles

Incorrect classifications can cause large premium adjustments. (Wexford Insurance Solutions)

Step 3: Verify Payroll Accuracy

The auditor will verify:

• Wages
• Bonuses
• Overtime
• Commissions
• Cash payments

They will cross-check payroll against tax filings and financial records to confirm accuracy. (Wexford Insurance Solutions)

Step 4: Confirm Independent Contractor Status

A major issue in New York audits is misclassification of workers.

If someone is treated as a contractor but should legally be an employee, the auditor may:

• Reclassify them
• Add their payments to payroll
• Charge additional workers’ comp premium

This is very common in industries like:

• Construction
• Cleaning services
• Restaurants
• Landscaping

Step 5: Cooperate with the Auditor

Audits may be done:

• Online
• By phone
• In person (field audit) (The Hartford)

Best practices:

• Provide only requested documents
• Assign one person to communicate with the auditor
• Keep organized files
• Ask questions if something is unclear

Step 6: Review the Audit Results Carefully

After the audit, you’ll receive an audit statement showing:

• Final payroll used
• Adjusted classifications
• Additional premium owed (or refund)

Review carefully for errors before paying.

If there are mistakes:

• Contact your broker
• Request corrections
• Provide additional documentation

What Happens If You Ignore the Audit?

Ignoring a workers’ compensation audit can cause serious consequences:

• Policy cancellation
• Penalties
• Higher estimated premium
• Difficulty obtaining future coverage
• Possible legal action (Insureon)

In New York, employers who fail to comply with workers’ comp rules can face significant financial penalties. (NYS Workers Compensation Board)
