How the New York payroll audit works
Workers comp carriers in New York reconcile estimated payroll against actual payroll Typically within 90 days of policy expiration, but can extend longer. after policy expiration. The audit can produce a refund (you over-estimated) or an additional premium bill (you under-estimated), and can reclassify workers between class codes based on the actual job duties seen on the books.
The audit is the carrier's reconciliation: the policy was bound on estimated payroll, but premium is rated on actual payroll. If the estimate was low, you owe additional premium; if it was high, you get a refund. The auditor also checks that every worker is on the correct class code based on actual job duties seen in the payroll records and any in-person walkthrough.
Records to keep
Pull together: payroll register by employee with class code allocation; quarterly 941s; year-end W-3 and W-2 totals; 1099-NEC totals for every contractor paid more than $600; certificates of insurance for every subcontractor (policy number, effective dates, carrier name); overtime hours and dollars by employee; written job descriptions for any worker on multiple class codes. Reconcile gross wages on the W-3 to the sum of W-2 box 5 plus 1099-NEC totals so the auditor can verify totals tie.
Overtime savings
Most New York class codes rate overtime at the straight-time wage. A worker earning $25 straight and $37.50 overtime contributes $25 per hour to rated payroll on an overtime hour, not $37.50. Document the overtime hours separately in the payroll register; if you cannot produce hours, the auditor rates 100% of the overtime wages at the full rate, which can add 5 to 10% to premium on payroll-heavy class codes.
Subcontractor exposure
A general contractor is liable for workers' compensation benefits to employees of an uninsured subcontractor. Without certificates of insurance for every sub, the auditor adds the sub payroll to your rated base under whichever class code matches the work performed. Keep certs in a binder with policy numbers, effective dates, and carrier names visible.
If the audit comes back wrong
You typically have 30 to 60 days from receipt of the audit results to file a written dispute with the carrier. Include the original payroll records, written job descriptions, certificates of insurance for subs, and any contracts. The carrier reviews and either adjusts or denies the dispute. If denied, New York insurance department complaint procedures and the rating bureau's reclassification appeal are next.

If you cannot pay, payment plans are usually available. Repeated under-estimation can lead the carrier to require monthly self-reporting on the next policy.

Can the auditor reclassify my employees in New York?
Yes. If the auditor sees that a worker on a clerical (8810) code spent material time on a higher-rate code, they can reallocate payroll between codes for the audited policy period.

Individuals classified as 1099 contractors are often deemed employees for workers' compensation purposes unless they meet strict independent contractor criteria. At audit, 1099 contractors without a certificate of insurance for their own workers comp typically get added to your rated payroll.
