Workers comp class codes affect price by determining the rate applied to each $100 of payroll in that classification. Higher-hazard work generally carries a higher rate than lower-exposure work. The calculation is only a starting point: experience modification, carrier pricing, assessments, credits, minimum premium and audit results can change the final cost. The carrier or NCCI must confirm every classification.
The basic payroll calculation
Divide payroll by 100, then multiply by the applicable rate. If a confirmed code has $200,000 in payroll and a hypothetical rate of $5.00, the manual-premium piece for that code begins at $10,000. That example is arithmetic, not a quote; real policy pricing includes other factors.
For one verified reference, roofing class code 5551 has a 2026 Florida filed rate of $6.75 per $100 of payroll. Whether 5551 applies to a particular employee or operation must still be confirmed by the carrier or NCCI. A code should never be selected only because its filed rate looks attractive.
Why one employee's duties matter
Suppose a contractor calls an employee a supervisor but the employee frames walls three days a week. The title does not erase the tool work. If payroll was estimated under a lower-exposure description, an audit may reassign it based on actual duties and applicable rules.
Mixed work creates the same issue. When payroll cannot be separated under the required records, rules may place all of an employee's earnings into a different or higher-rated classification. Daily job and time records are more persuasive than year-end guesses.
Multiple codes do not always mean savings
Distinct crews can support multiple classifications, but only if the operations qualify and the records stay clean. Adding codes without changing payroll discipline can create confusion rather than a discount. Ask exactly what duties belong in each code and how occasional work is handled.
- Map every employee to normal and backup duties.
- Confirm classification before configuring payroll categories.
- Record time when work occurs, not after audit notice.
- Review employees who change roles or help another crew.
- Keep estimates aligned with new contracts and hiring.
The experience mod is a separate multiplier
Classification rates describe expected exposure for the work. An experience modification factor compares qualifying loss experience with expectations and can adjust premium. A business can have correct codes but still pay more because of its loss record.
A rising experience mod narrows voluntary market options, and Florida's assigned risk market, the FWCJUA, prices in tiers: its best tier is for rated employers with an experience modification below 1.00, no lost-time claims and medical-only claims under 20% of premium, the next tier covers modifications from 1.00 to 1.10 on the same claim criteria, and everything else falls to the highest-priced tier; employers who cannot place coverage voluntarily must show a good-faith effort before using Florida's assigned risk market, usually at a materially higher cost. Contractors who lose voluntary options may face the assigned risk market at a much higher overall cost. That is not a classification fix; it calls for loss control, accurate data and a deliberate renewal plan.
Audit is where the estimate meets reality
The policy begins with projected payroll and operations. After the term, an audit compares those estimates with actual records. Higher payroll, newly discovered work or unsupported subcontractor treatment can increase the balance. Lower verified payroll may reduce exposure subject to policy terms.
Review payroll and codes quarterly. If the company begins roofing, structural demolition or heavy recovery after binding, report it. An endorsement during the year is usually easier to understand than a surprise reclassification months later.
People Also Ask
Does a higher code number mean a higher rate?
No. The digits are identifiers, not a price scale. The filed or carrier rate attached to the confirmed code matters.
Can I move payroll to a cheaper code?
Only when the duties, operations, rules and records support that code. The carrier or NCCI must approve it.
Why did my audit change the classification?
The auditor may have found duties, operations or records that did not match the original estimate. Ask for the factual and rule basis.
