Why Workers Comp Audits Are More Aggressive in 2026
Workers compensation carriers in New York have been under significant loss pressure since 2023. Inflation has driven medical costs higher, legal settlements have grown, and complex return-to-work situations extended many claims well beyond normal duration. In response, carriers including NYSIF and private market insurers have dramatically increased audit intensity for the 2024-2026 policy years.
For Nassau County and Long Island contractors, this means the simple end-of-year audit phone call has been replaced by in-depth reviews of payroll records, subcontractor certificates, 1099 forms, bank statements, and project files. Contractors who are not prepared are seeing surprise audit bills of $10,000 to $80,000 or more.
If a subcontractor you hired cannot produce a valid workers comp certificate — or if their certificate was expired during any part of the period you used them — your carrier will treat their payroll as yours and charge you premium on it. On a large job with multiple subs, this can add tens of thousands of dollars to your audit bill.
The 5 Most Common Audit Errors We See in Nassau County
- 1. Misclassified employees. A clerical or office worker accidentally coded under a field laborer code. Rates can differ by 10x or more. Always confirm each employee code matches their actual duties.
- 2. Missing subcontractor certificates. The most common and most expensive error. Collect certificates before work begins, not after. Create a certificate tracking log for every sub on every job.
- 3. Expired certificates. A certificate that expired mid-project does not cover the full period. Carriers charge premium for uncovered gaps. Monitor expiration dates and require renewals before they lapse.
- 4. Overtime not properly excluded. New York allows contractors to exclude the excess premium portion of overtime pay from WC calculations. Many contractors do not know this, and auditors do not volunteer the information.
- 5. Materials and equipment payments included. Payments to subs that are documented as materials-only or equipment rental are generally excludable from WC payroll. Separate invoicing is critical.
How to Prepare Before Your 2026 Audit
- Collect and organize all subcontractor WC certificates for the policy year — one per sub, confirming coverage for the exact dates of work
- Prepare payroll by classification code — match each employee to their actual work duties, not their job title
- Calculate and document overtime premium separately from straight-time wages for exclusion purposes
- Organize invoices from subs that include both labor and materials — identify which portions are excludable
- Review your original estimated payroll — if actual payroll will differ significantly, discuss with your broker before the audit
What to Do If You Receive a Surprise Audit Bill
