Does Your Workers’ Comp Class Code Match the Work Being Done?

The short answer: your class code should reflect what employees actually do on the job, not what your company is called or what industry you're in. If the duties listed in your payroll records or job descriptions don't match the classification on your workers' compensation policy, a premium audit can reassign payroll—sometimes to a higher-rated code—and generate an unexpected balance due. The time to check is before the audit, not after.

This article walks you through the records that auditors use to verify classifications, explains the payroll-assignment rule that creates the most exposure for employers with mixed-duty workers, and provides a worksheet you can complete using your own files.

A class code is meant to capture the actual exposure created by the work a person performs, not their title or the name of the business. A warehouse worker who also drives a forklift and occasionally climbs ladders to reach high shelving presents a different risk profile than a clerk who takes orders by phone. Both might work for the same company under the same industry label, but their classifications can differ.

The way payroll is assigned matters a great deal. According to Travelers' workers' compensation premium audit guidance, if an employee's records don't show the actual payroll applicable to each classification, the entire payroll for that individual must be assigned to the highest-rated classification that represents any part of their work. Estimated or percentage allocations of payroll are not permitted as a substitute for actual records. (Preparing for a workers compensation premium audit)

That rule is the central reason why employers with workers who perform more than one type of duty need precise time-and-task records—not rough estimates—if they want to preserve a split-classification arrangement.

Understanding which documents auditors examine helps you see where a classification dispute can be supported or undermined.

According to Travelers, payroll reports serve as the primary source document during a workers' compensation audit. The auditor then validates those figures against tax records, which function as a secondary verification source. Tax forms cited in the Travelers audit guidance include Federal 941 forms, state unemployment wage reports, 1099s, Schedule C (1040c), Form 1120, and Form 1065. Beyond payroll and tax records, the auditor may also examine checkbooks, cash receipts, and general ledgers to identify payments not captured in payroll records.

For assigned-risk or residual-market policies audited virtually, Travelers notes that the National Council on Compensation Insurance (NCCI) recommends that the insurer obtain a picture of your operations—or of your job site for construction and special trades. If you maintain office staff, a picture of their workspace may also be requested. (Premium audit required documents)

When an audit is completed online, the system will specify which documents are needed once you register. In-person audits typically list required documents in the appointment confirmation letter. (Premium audit required documents)

The practical implication: the classification conversation doesn't begin with what you say your employees do—it begins with what your records show.

Many small employers have workers who perform more than one type of task. A technician who installs equipment might also do some office-based scheduling. A retail employee might also make local deliveries. In these situations, there may be more than one class code that applies to a single person.

However, splitting one employee's payroll across two or more classifications is only permitted if your records document the actual hours or earnings tied to each type of work. If the records don't make that separation clear—based on actual time, not estimates—then the entire payroll for that employee defaults to whichever code has the highest rate among the duties performed. This is not a penalty; it is the standard rule when records are insufficient to support a split. (Preparing for a workers compensation premium audit)

If you believe a worker's payroll has been consolidated into a higher-rated code incorrectly, the question to ask your insurer or agent is: which records would be needed to support a classification split for this employee's duties?

Complete this worksheet for each employee—or each job role if duties are identical across a group. Use your actual payroll system, time records, and job descriptions as source material. This is an organizational tool, not an insurance document, and it does not establish a class code or determine compliance.

For each employee or role, record:

Field	Your Entry
Employee name or role identifier
Department or cost center
Job title (as listed in HR or payroll system)
Primary duty (describe in plain language, e.g., "loads pallets using forklift")
Secondary or occasional duties (list each separately)
Percentage of time on each duty if supported by time records
Are time records documented in writing (timesheet, job ticket, dispatch log)?	Yes / No
Source document that supports the time breakdown
Class code currently on your policy for this role
Does the current code description match the primary duty?	Yes / No / Unsure
If No or Unsure: What specific duty seems misclassified?

For any employee where secondary duties are present, also note:

• Which payroll records separate earnings by duty type?
• Are those records generated automatically (e.g., by a timekeeping or job-costing system) or manually estimated?
• If manually estimated: is there any underlying source record (clocked hours, dispatch records, job tickets) that would support those estimates?

Once you've completed the worksheet, compare it against the class codes listed on your current policy declarations or audit worksheet. Where you see a potential mismatch, that is the specific question to raise with your insurer, agent, or a licensed professional before the audit.

Based on the audit documentation requirements described by Travelers, these records are the most relevant to a classification question:

Primary payroll evidence:

• Payroll reports for each employee, covering the full policy period
• Timesheets, job tickets, dispatch logs, or time-and-attendance system exports that tie hours to specific duties
• Payroll service reports, if applicable (some payroll providers can pre-populate audit systems)

Verification (tax) records:

• Federal 941 forms covering the policy period
• State unemployment wage reports
• 1099s, Schedule C, Form 1120, or Form 1065 as applicable to your business structure

Operational records:

• General ledger, checkbook, or cash receipts if payments outside the payroll system may affect audit totals
• Job descriptions or HR records describing what employees are hired to do
• Photographs of work areas or job sites (particularly relevant for construction or trades under a virtual audit)

Keep copies of filed tax forms that fall within your policy term. Travelers notes that if your policy period falls mid-month, providing the most recent four filed quarterly or annual reports that closely align with your policy period is acceptable.

It is worth being specific about what does not determine a class code: your industry category, your business name, or a general description of what your company does. Classification is applied at the level of individual job duties. Two businesses in the same industry can carry different codes for the same job title if the actual work differs—for example, one employer's "field technician" may work entirely outdoors on heavy equipment while another's visits residential customers indoors. The industry label captures neither.

This is why reviewing your own records against the code descriptions—rather than relying on an industry-level assumption—is the productive starting point. If you want to understand how classification interacts with the broader structure of workers' comp pricing, the Workers' Compensation Insurance overview at PolicyBenchmark explains how coverage is organized and what audits are designed to accomplish.

For a closer look at how payroll figures and experience modifiers interact once classification is established, the Workers' Comp & EMR Impact Calculator lets you enter your own payroll and modifier figures to explore arithmetic on a confirmed pre-mod subject premium. It does not calculate an official EMR, supply market rates, or assign class codes—but it can help you organize the numbers before a renewal conversation. The article Workers' Comp Costs: Payroll, Classification and Quote Differences explains how classification choices flow through the pricing structure.

If your worksheet identifies a potential mismatch, consider asking these specific questions before or during the audit:

• Which class code is currently assigned to this employee or job role, and what is the written description for that code?
• What records would be needed to support a split classification for an employee who performs duties across more than one code?
• If a reclassification is warranted, does it apply retroactively to this policy period or prospectively at renewal?
• For assigned-risk policies: does the NCCI have specific documentation requirements for the duties in question?

These questions don't require a resolution before you gather records—but having the worksheet completed before you ask them makes the conversation more productive.

Complete the employee duty worksheet above using your actual payroll and time records. Compare what you find against the codes on your current policy. If you identify a discrepancy, bring your source documents to the conversation—not an estimate, and not a job title alone.
