Workers' comp audit checklist

Workers' comp audit checklist: what to gather before the review starts

If you want a practical list instead of a vague explanation, start with the document groups below.

Short answer

A useful workers' comp audit checklist should cover more than payroll totals. It should help you gather policy details, payroll and tax records, subcontractor proof, owner/officer support, and the business records that may need explanation.

The goal is not to guess what an auditor will ask line by line. The goal is to get the main record groups into one place in a cleaner order before follow-up starts.

The main checklist categories

Use this as the practical starting list before you move into reconciliation and packet-building.

CategoryExamplesWhy it matters
Policy and business basicsCarrier, policy number, policy period, entity name, contact detailsKeeps the audit tied to the right business and time period
Payroll recordsPayroll summaries, payroll journals, period-level totalsProvides the base payroll view for the policy period
Tax forms941s, W-2 summaries, 1099 summaries where applicableHelps explain totals and differences across reporting views
Subcontractor supportVendor list, amounts paid, COIs, related proofImportant when subs or 1099 labor are part of the audit story
Owner/officer supportRole details, payroll support, notes on treatment questionsMakes it easier to separate or explain owner-related records
Other business recordsGeneral ledger, payment records, operations descriptions, follow-up notesHelps explain payments or duties that may trigger questions

Common checklist mistakes

  • Waiting for a second auditor request before gathering the obvious record groups
  • Using calendar-year totals when the policy period cuts across quarters or years
  • Keeping subcontractor payments and COIs in separate places with no matching trail
  • Treating owner/officer support as an afterthought
  • Having no place to note why two totals do not line up exactly

How to use the checklist in a calmer order

  1. Confirm the policy period and entity first so you gather records for the right time frame.
  2. Pull payroll reports and tax-form support into one folder before comparing totals.
  3. Build a separate list for subcontractors, amounts paid, and certificate status.
  4. Flag anything that needs explanation instead of hoping it will not come up.
  5. Move into the full kit if you need reconciliation worksheets, COI tracking, and a packet index.
