Audit Prep Checklist
Gather these documents before your audit to reduce stress and avoid surprises.
A) Payroll and Employee Records
- ☐Payroll summary by employee for the policy term (gross wages and overtime breakout)
- ☐Job titles plus a short description of job duties
- ☐Quarterly payroll tax filings used to verify payroll (e.g., federal Form 941)
B) Subcontractors and Contract Labor
- ☐Payments to subcontractors/contract labor (name, dates, amounts, work performed)
- ☐COIs for subcontractors (workers' comp, plus GL if required by contracts)
- ☐Material cost breakout where relevant (labor vs materials clearly separated)
C) Business and Financial Records
- ☐General ledger or accounting ledger for the policy term
- ☐Profit and loss statement for the policy term
- ☐Brief description of business operations and how work is performed
- • Missing subcontractor COIs and unclear contract labor records
- • Payroll that does not clearly separate overtime and job duties
- • Scrambling to explain how work was performed during the policy term
COI System
Use this system to stop COI chaos and respond faster to customer and GC requests.
COI Intake Form
Use this every time a COI is requested
- • Requested by (customer/GC)
- • Project name / job number
- • COI needed by (date)
- • Recipient email
- • Required coverages: WC, GL, Auto, Umbrella
- • Special requirements: Additional insured, Waiver of subrogation, Primary/noncontributory wording
COI Quality Check (60 seconds)
- ☐Named insured matches subcontractor/legal entity name
- ☐Effective dates cover the full period of work
- ☐Workers' comp is listed (if required)
- ☐If additional insured is required, confirm the endorsement exists (not just COI wording)
A certificate of insurance is informational and does not change the policy. If you require insured status, you typically need the policy endorsement.
COI Request Tracker
Copy into a spreadsheet to track all COI requests
| Date | Vendor/Sub | Work | State | COI rec'd? | Dates ok? | WC ok? | AI needed? |
|---|---|---|---|---|---|---|---|
Keeping this tracker updated saves hours during premium audit reviews.

Return-to-Work Starter Template
"Hi [Employee Name], We are glad you are safe. We want to support your recovery and return you to work as soon as medically appropriate. If your provider approves restrictions, we can often offer modified duty options such as light administrative tasks, training, documentation work, or other duties aligned with restrictions. Please share any work restrictions, and we will confirm next steps and schedule."
EMR Quick Facts
An experience modification factor (often called EMR or e-mod) is a multiplier used to adjust workers' comp manual rates based on loss experience. It is produced by NCCI or the state rating bureau, depending on the state.

Workers' compensation audit preparation is one of the highest-ROI compliance activities a small business can invest in. Misclassifications caught during audit — not before — result in retroactive premium adjustments that often surprise employers at the worst possible time, typically during renewal when cash flow pressure is already high. Use our OSHA safety assessment alongside this audit kit to ensure your safety program documentation supports your classification decisions. Visit the HR resource library for additional compliance frameworks, and schedule a consultation to discuss how a PEO can manage your workers' comp coverage and audit process entirely on your behalf.
