Car Wash Workers' Comp, Payroll and Class Codes

Car wash workers' comp premium is generally a state-approved rate per $100 of payroll in the class the insurer assigns (some states and state funds use a different base, so ask), adjusted by an experience mod (a multiplier built from your claims history, where 1.00 is the baseline) that usually follows the business to you. Class codes vary by state: Massachusetts places car washes in 8380, California uses 8387(3), and the insurer's assignment and the bureau's rulebook control. This guide is for the buyer who wants to check the class, the payroll estimate and the ownership change report before the first audit, so a retroactive bill is not a surprise.

The short answer

The class code describes your business, not each worker's job, and the insurer assigns it. Ask what code is on the policy and read the bureau's description for your state.
If you take over the seller's whole operation, whether you bought the entity or the assets, the seller's claims history and mod usually follow you. Many policies require you to report an ownership change within 90 days.
The payroll on the policy is an estimate. The final premium comes from an audit after the policy ends, so keep payroll records by role from day one.
In North Dakota, Ohio, Washington and Wyoming, workers' comp generally must come from the state fund (Wyoming's requirement is mainly tied to listed hazardous industries, so confirm it for a car wash), and some employers may qualify to self-insure, so ask the state agency.

Which class code does a car wash use?

Premium is built from payroll by class. At a wash, attendants, finishers, cashiers and often mechanics sit in one class, so that class's rate and your mod move the whole bill. Class codes describe the employer's business in a state, and the insurer and the rating bureau decide which applies.

For car washes, the Massachusetts rating bureau's classification page for code 8380 says it includes all types of car wash facilities (attendant, coin-operated self-service and fully automatic), cashiers, mobile vehicle power washing and new car clean-up and detail shops. Many lookup tools also map car washes to 8380, but each state or bureau publishes its own wording, so treat 8380 as a code you may see, not one to assume. California is different: its bureau uses 8387(3), Automobile or Truck Washing Facilities, which covers washing, waxing and polishing customers' vehicles on a fee basis, including at customers' locations, as described on the bureau's classification page. The bureau has had a proposal to clarify the wording, so confirm the current text with it.

Car wash duties and how class codes generally treat them
Who	What they do	How classification generally treats it
Attendants, washers, finishers	Rinse, dry, apply wax, vacuum, clean interiors, guide cars onto the conveyor	The wash's governing class for the state
Cashiers and kiosk staff	Take payment, sell memberships	Within the car wash class in the Massachusetts description; confirm in your state
Maintenance mechanics	Service the tunnel, clear jams, work near moving machinery	Often treated as part of the wash's class, but this is a question for the insurer and the bureau for your state, because mechanics carry the highest machinery risk
Office staff	Bookkeeping, scheduling in a separate area	A clerical standard exception (commonly 8810) may apply only if the duties and workspace meet the rule
Fuel or convenience store staff at a combined site	Sell fuel, run a store	May be rated separately only where the state's rules treat the operations as separate and your payroll records support it. In Massachusetts, for example, gasoline sales share the car wash code, while a convenience store can be in a different one. Ask the insurer
Mobile detailers or power washers	Wash vehicles at customers' sites	Included in some bureaus' car wash class; building exterior power washing is not

Can I split a worker's pay between classes?

One worker's pay can be divided between two classes only when both classes properly apply to your business under your state's rules and your records show actual time and pay in each. Estimates and percentage splits are not allowed under the National Council on Compensation Insurance (NCCI) rule on interchange of labor, and without proper records all of that worker's pay goes to the highest rated class involved. At a car wash this matters mainly at a combined site, for example a worker who covers both the wash and a separately classified store. If mechanics already sit in the wash's class, there is nothing to split. Keep time and pay records by role from the first week. See how class codes get corrected and the plain definition at workers' comp class code.

Will the seller's claims history and mod follow me?

The mod compares your claims history with similar businesses, so two slip claims at the seller can raise your premium after you close. Usually the mod follows the business. Under current NCCI rules an entity that changes ownership retains or transfers its experience to the acquiring or successor entity unless the plan specifically excludes it. Buying the stock or membership interests counts as an ownership change, and so does buying the assets and taking over the operations. If you buy the seller's whole operation into a new company, you generally do not start at 1.00. If you buy one site of several, whether experience moves depends on whether the seller's insurer can split out the data for that site. Excluding the seller's experience is rare and needs a near-complete change of owners plus a change in operations and hazards that changes the governing class, which a straight car wash purchase is unlikely to meet. A wash's payroll is mostly in one class, and at a small site a couple of claims can move the mod noticeably. How much depends on the size of the payroll and the expected losses for the class.

Many policies require you to report the change to the insurer within 90 days, and the rating bureau decides the effect. Under current NCCI rules, a recalculated mod applies back to the date of the change, up or down. Failing to report is treated as a possible attempt to avoid a higher mod, not as a fine, and can lead to a corrected, often retroactive, mod. Independent bureaus, including New York and California, have their own ownership rules and timing, so ask your insurer how your state treats it.

A hypothetical example. A single-tunnel wash large enough to have a mod has a 1.30 mod after two claims: a worker who slipped on the wet tunnel exit and a hand cut while clearing a jam. The buyer closes into a new company, and because the payroll is small, the two claims weigh heavily. The buyer reports the change on day 120. In a state that follows NCCI's rule, the bureau can recalculate the mod back to the closing date and the policy is rebilled. Questions to settle before closing: how will you learn the mod, who bears a retroactive bill under the purchase agreement, and has the insurer been told? See reviewing an experience mod for errors and the definition of experience modification rate.

How do payroll estimates and audits work for a car wash?

The premium on the policy is an estimate. The final premium is set after the policy ends from actual payroll and the correct class, and you pay any balance or receive a refund. The insurer can audit your records during the policy and for up to three years after it ends. Payroll for premium purposes generally includes wages, bonuses and commissions. The overtime premium and expense reimbursements can be treated differently from state to state, so ask your insurer or the bureau rather than assuming.

Tips deserve their own line at a wash. Under NCCI's payroll rule, wages, bonuses and commissions count as premium payroll while optional tips do not, but state rules vary and a tip pool, a manager's share or a mandatory service charge may be treated differently. Keep tip and bonus records separate from base wages so an auditor can classify each. Tip handling is also a wage and hour question, covered in inherited wage and hour exposure.

Washes carry weather-driven staffing and seasonal swings, so an estimate built from the seller's slow year can produce an audit bill, and one built from a peak can tie up cash. In a stock purchase the insured company is the same, so a post-closing audit can bill it for pre-closing payroll. In an asset purchase the audit balance on the seller's policy is usually the seller's, and the purchase agreement decides who bears the cost, so ask your attorney. A pay-as-you-go arrangement bills each payroll cycle but does not remove the audit. It is generally tied to a specific policy and payroll account, so have your own in place at closing, and ask the carrier and payroll provider about final audit terms. Read payroll estimates and audit bills and pay-as-you-go workers' comp.

What else changes workers' comp for a car wash: contractors, owners, PEOs and state rules?

Contractors. Car wash workers are normally employees. If the seller used outside detailers, mobile crews or a staffing agency, get certificates of coverage, because uninsured subcontractors' pay can be added to the audit under the policy wording. See 1099 contractors and the audit.
Owners and officers. Whether your own pay counts toward premium, and whether you can elect to be covered or excluded, depends on your state and your entity type. Ask the insurer and confirm any election in writing. See reviewing workers' comp after an acquisition.
Professional employer organizations (PEOs). If the seller's staff were on a PEO policy, that coverage may not continue for your new company. See PEO or your own workers' comp after an acquisition.
State funds. In North Dakota, Ohio, Washington and Wyoming, coverage generally must come from the state fund (for most employers; check Wyoming's scope and any self-insurance option with the state agency), and those policies generally do not include employers liability, so a stop gap endorsement is common. In Washington, a buyer can become liable for the seller's unpaid workers' compensation amounts unless it gives the state agency written notice of the purchase and no assessment is issued within 180 days (Revised Code of Washington, section 51.16.200). In Ohio, the Bureau of Workers' Compensation can transfer a predecessor's experience and, in listed situations, its obligations to a successor (Ohio Administrative Code rule 4123-17-02). Ask your attorney how these apply to your deal.
Combined sites. If the wash also sells fuel or runs a store, expect payroll to be split by operation under your state's rules, with time and pay records to support it.
California. A car wash employer registering with the state must show proof of workers' compensation, usually a certificate naming the licensing unit, and an ownership or legal name change can force a new filing. See contracts, licenses and bonds for a car wash.

What should I do about workers' comp in the first 90 days?

Get the policy's information page and ask what class code or codes are on it, and compare them with your real duties by role.
Ask for the experience rating worksheet, or confirm that the business is too small to have a mod.
Report the ownership change to the insurer, and to the rating bureau through the insurer or the bureau's own process, within 90 days.
Rebuild the payroll estimate from your own plan, with maintenance, hand finishing and any fuel or store staff separated.
Keep time and pay records by role so a split is supportable at audit.
Ask for the injury history by type. Slips, trips and falls are the leading injury type in one insurer's guide, and chemical and machinery claims are the severe ones, so your safety plan and your loss runs should line up.

For the whole line, read reviewing workers' comp after an acquisition. Morrow can check the class, the mod worksheet and the ownership change filing against what you actually do, and request quotes. The rating bureau decides the mod, and quotes depend on carrier underwriting.

Frequently asked questions

What workers' comp class code does a car wash use?

It depends on the state and the rating bureau, and the insurer assigns it. The Massachusetts bureau places car washes in 8380, lookup sites map car washes to 8380 in other states, and California uses a separate classification, 8387(3). Check the code on your policy and the bureau's description for your state.

Do I inherit the seller's experience mod when I buy a car wash?

Usually, if you take over the seller's whole operation. Under current NCCI rules, experience transfers to the acquiring or successor entity in both stock and asset purchases that take over operations. If you buy only part of the operations, ask whether the insurer can split out the data. Excluding it is rare. Ask for the worksheet before closing.

How long do I have to report the ownership change?

Many workers' compensation policies require reporting within 90 days. Under current NCCI rules a recalculated mod can be applied back to the date of the change, so reporting late does not avoid an increase. Independent bureau states differ, so ask your insurer how your state treats it.

Can I put my cashiers or mechanics in a cheaper class?

No. The class describes the business, not each job. A worker's pay can be divided between classes only when both classes properly apply to your business and records show actual time and pay in each. A clerical exception applies only if the duties and workspace meet the rule.

Do I need workers' comp in Texas?

Most private employers in Texas may choose not to carry it, but a lender, landlord or customer contract may require it, and opting out has consequences, so ask your attorney and broker before you decide.
