A painting contractor's workers' compensation premium is built from payroll in each class code, and the class follows the work the crews actually do, not the job titles on a payroll sheet. Class codes, rating bureaus and rules vary by state, and the insurer assigns the code. The final premium is set at audit, so the best protection for a new owner is clean payroll records and an honest description of the work. This guide is for the entrepreneurship through acquisition (ETA) buyer or search fund CEO who just bought a painting company with painters on W-2 pay, helpers on 1099 forms or both.
The short answer
- Class codes classify the business and its operations in a state. Painting is commonly associated with one code, but tall metal structure work, shop work, clerical and sales roles can be rated differently.
- Premium is an estimate. Actual payroll and the correct classes set the final bill at audit, and the insurer can audit for up to three years after the policy ends.
- Uninsured subcontract painters can be charged to your policy at audit as if they were your employees, so certificates and records matter.
- Report the ownership change to the workers' comp insurer, generally within 90 days. The seller's experience mod (a multiplier on your premium based on the company's claims history; above 1.00 raises it, below 1.00 lowers it) usually follows the business. Under National Council on Compensation Insurance (NCCI) rules it can be recalculated back to the date of the change. New York times it differently, and other independent bureaus may have their own rules, so confirm with the carrier or bureau.
- Never move an employee to a cheaper class. Correct real errors, with records behind every split.
How do a painter's duties map to class codes?
Rules differ by state and bureau, so treat the table as a conversation guide, not an assignment. The examples use Massachusetts, where the rating bureau publishes its rules, and a third-party lookup shows how other states title the same code. Your insurer assigns the class from your actual operations.
| Role or operation | How rules commonly treat it | What to confirm |
|---|---|---|
| Field painters, helpers and crew leads doing prep, taping, masking, scraping, sanding, priming and painting | The painting class for the state. In Massachusetts, class 5474 covers interior and exterior painting of residential or commercial structures, and includes surface preparation and scaffolding erected for painting | The class text for your state and whether the carrier used it |
| Work on tall metal structures or bridges | In Massachusetts, metal structures over two stories and bridges of any height are rated in a separate, higher-hazard class (5037), while metal storage tanks stay in 5474 | Whether any jobs fall in that category |
| Shop-only painting, such as refinishing in the employer's own shop | In Massachusetts, class 9501 covers painting in the employer's own shop. A contractor that does both on-site and shop work falls under 5474's shop operations inclusion there | Whether shop work is separate or part of the main class |
| Drivers who carry materials and equipment | Class titles in many states include drivers, so they may not need a separate class, which depends on the state's rules | The class title in your state |
| Estimators and project managers who visit sites | Outside salespeople can be rated in a standard exception class (8742) only if their duties meet the definition | Whether they also paint, which can keep them in the main class |
| Office staff | Clerical office staff can be rated in a standard exception class (8810) only if they do clerical work only and the clerical area is separated from the shop and field operations | Duties and the office layout, not titles |
| Wallboard installation or taping beyond incidental patching | In Massachusetts this goes to a different class (5445), not painting | Whether the crews hang or finish drywall |
Outside Massachusetts, class 5474 is commonly listed for painting contractors, usually under a title that names painting along with shop operations and drivers, though some states use different wording, and California, Pennsylvania and Delaware use their own classification systems. Treat it as a starting point for the conversation, not your assignment. Confirm the code and its wording for your state with your carrier or the state's rating bureau.
Will my state use the same class codes and rules?
Ask the carrier which class it assigned, in which state's manual, and why. NCCI handles ratemaking data for most states, but eleven states run independent rating bureaus, including Massachusetts, New York, California and Pennsylvania. Our new owner review of workers' comp covers the wider picture. For a painter, two state differences matter most:
- Different class systems. California, Pennsylvania and Delaware use classification systems that differ from NCCI's, so codes from NCCI material do not carry over to them directly.
- State fund states. In North Dakota, Ohio, Washington and Wyoming, workers' comp must be bought from the state fund and private insurers cannot sell it. The state fund policy does not include employers liability, so ask how stop-gap cover is arranged. Employers usually add it to the workers' comp policy for other states or, for an employer only in a monopolistic state, to the general liability policy. In Washington the same company must also register as a specialty contractor.
How do payroll estimates and audits work for a painter?
Painting payroll swings with the weather, so an estimate made in a slow month can miss badly. The final premium is set after the policy ends from actual payroll and the correct classes, and you pay any balance or get a refund. The insurer can audit your records during the policy period and for up to three years after it ends. Payroll for premium purposes includes wages, commissions, bonuses and paid leave, with some exclusions. Four points help:
- Keep time records that show actual hours and pay by class. One employee's pay can be split between two classes only if the records show actual time and pay in each, and pay in a standard exception class such as clerical cannot be divided this way. Without records, all of that pay can go into the highest-rated class involved.
- Update the estimate with the carrier when the crew size changes, as it may after a purchase.
- Treat the audit as a cash item. A balance due at the end of the first policy year hits the same cash that services your debt, so ask the carrier for an updated payroll estimate after closing and keep a reserve.
- Know whose audit it is. In a stock or membership interest purchase, the company itself owes the audit balance, so a final audit can bill the buyer-owned company for payroll from before closing. In an asset deal the balance on the seller's policy usually stays with the seller. The purchase agreement decides who bears the cost, so ask for the last audit and ask deal counsel who bears any true-up.
Pay-as-you-go billing can smooth cash flow but does not remove the audit. See workers' comp payroll estimates and audit bills and pay-as-you-go workers' comp payment plans.
What if I use subcontract painters or 1099 crews?
This is a common audit exposure in the trade. Under the standard policy, the premium base includes payroll for your employees and also pay to all other persons engaged in work that could make the insurer liable, which is how uninsured subcontractors end up on the bill. At audit an uninsured subcontractor is generally classified as if its workers were your employees. If you cannot document an uninsured subcontractor's payroll, rating manuals may charge a set share of the contract price instead. North Carolina's manual, for example, uses 90 percent for labor-only work and 50 percent for labor and materials. Other states and bureaus may differ.
The Bureau of Labor Statistics reports that 31 percent of painters are self-employed, so one-person subcontractors are common. The U.S. Department of Labor says that misclassifying employees as independent contractors is a serious problem, and state tests for who is an employee differ. That is not a legal conclusion about any worker, so confirm classification with your employment attorney.
A hypothetical example. A one-person painter hired for a $20,000 job has no workers' comp policy and falls from scaffolding. The contractor's certificate file shows nothing for him.
Several questions follow at once. Was he an employee under the state's test? Can the contractor be responsible for his benefits? How will the audit treat his payroll? Collecting certificates, written agreements and invoices before the job is much cheaper than answering those afterward. See 1099 contractors and the workers' comp audit and do your subcontractors carry required coverage.
What about the owner's own coverage?
Whether owners, officers and members are included in or can be excluded from workers' comp depends on the state and the type of entity, so confirm with the carrier and the state's workers' comp agency before you change anything. An owner who works only in a separated office may qualify for the clerical class. An owner who visits job sites, supervises crews or climbs ladders generally does not meet the clerical test and is often rated with the painting crews, depending on the state's rules. Ask the carrier how your own duties and pay would be treated before you decide whether to be on the policy. If you are not on the workers' comp policy, ask how a fall or strain of your own would be paid for. Disability insurance sits outside Morrow's focus, so ask a specialist about that side.
What do I report when I buy a painting contractor?
Under the policy, an ownership change generally has to be reported to the insurer within 90 days, whether or not the business currently has a mod. Under NCCI rules, a change in ownership includes buying the stock or membership interests, buying the assets and taking over the operations, a merger and forming a successor entity. Three points matter most:
- Expect to inherit the mod. The seller's past payroll and claims history usually follow the business. Under NCCI rules a recalculated mod applies back to the date of the change, and NCCI can revise the current mod and up to two prior mods. Dropping the seller's experience is rare: it needs a near-complete change of owners, a change in operations big enough to change the class code, and a change in the work process and hazards.
- Report on time. Failing to report can be treated as an attempt to dodge the mod.
- Ask for the last two audits. Look for subcontract payroll, 1099 helpers and seasonal labor added at audit.
State rules differ, so confirm the current rule with the carrier or the state's rating bureau:
- New York's published manual has used the same 90-day rule, but ties the start of a recalculated mod to when you report. Confirm with the current manual.
- California's rating bureau treats a change as material only when the prior owners hold less than half afterward, with further tests for employees and operations. Confirm with the current plan.
- In Ohio, a buyer that wholly succeeds a business takes over its experience, and the state can also transfer the predecessor's obligations in listed situations.
- In Washington, a buyer can become liable for the seller's unpaid workers' comp amounts unless it gives the Department of Labor and Industries written notice and no assessment follows within 180 days, under that state's workers' comp statute.
In an asset purchase the buyer cannot simply take over the seller's policy, so a new policy and payroll account must be ready at closing. See new owner review of workers' comp and changing payroll providers without a workers' comp gap. Our guide on what drives insurance cost for a painting contractor covers the pricing side.

Frequently asked questions
What workers' comp class code do painters use?
It depends on the state and the bureau, and the insurer assigns it. A code often associated with painting contractors is 5474, but that is not the same everywhere, and some states, including California, Pennsylvania and Delaware, use different classification systems.
Can my painters be split between painting and clerical codes?
Generally no. Clerical office employees can be rated in the standard clerical class (8810) only if they do clerical work only, in an area separated from the shop and field operations, and pay in a standard exception class cannot be divided between classes. A painter who also does office work is normally rated in the painting class. Rules vary by state and bureau, so ask the carrier how it classified each role.
Do my 1099 painters count for the premium audit?
They can. If a subcontractor has no workers' comp of its own, the audit can charge their pay to your policy as if they were employees. Certificates and written agreements help, and state tests for who is an employee differ.
Do I inherit the seller's claims record and workers' comp rating?
Under National Council on Compensation Insurance rules, the past experience of a business usually transfers to the new owner in both stock and asset purchases where you take over the operations. The rating organization makes the call, and rules differ in some states.
