Insurance premium audits for NEMT companies: payroll, contract drivers, and the bill after the policy ends

What is a premium audit, and why does the bill come after the policy ends?

A premium audit is the insurer’s look back at the numbers your price was built on. When you buy workers’ compensation, general liability, or some auto policies, you estimate the coming year’s payroll, sales, receipts, or miles, and the insurer charges a deposit on that estimate. After the term ends, it measures the real figures, then bills you for the shortfall or refunds the overpayment.

The standard business auto form spells this out in its premium audit condition. The estimated premium is credited against the final premium, you are billed for any balance, and you get a refund if the estimate was higher. Virginia’s insurance regulator describes the same result for commercial policies in general: after the audit, the insurer either collects more or refunds the difference.

A company that grew during the year usually owes money at audit, because new broker contracts, more drivers, and more vans all raise the exposure the policy was priced on. The workers’ comp guide explains how payroll and class codes set that premium in the first place; this guide covers what happens when the insurer checks your numbers.

Which NEMT policies get audited?

Three lines are audited routinely, and each counts something different.

• Workers’ compensation. Rated on payroll by class code. Virginia’s guide lists it first among the lines that are typically audited.
• General liability. California’s insurance department says the base can be floor area, payroll, or gross sales, set by the class code your insurer assigns. The audit confirms whichever base your policy names.
• Commercial auto. Virginia’s guide says business auto policies may be audited to confirm which vehicles you own or operate and how you use them. Some passenger carriers are also rated on receipts or miles, which turns the auto policy into a fully auditable one (covered below).

Before you sign, find out from your agent which policies are auditable and on what base. Your estimate for that base is the number the audit will test.

Contract drivers: the line that grows the bill

Payments to drivers on 1099s can add a large amount to an audit bill, because the insurer can treat them as your payroll. Virginia’s guide warns that when you cannot show proof a subcontractor has its own workers’ comp, the insurer can count the amount you paid that subcontractor as your payroll. Whether those drivers are truly independent is a separate question with its own tests, covered in 1099 or W-2 drivers. The audit does not wait for that answer. It looks for a certificate.

North Carolina’s Basic Manual shows how an auditor prices the gap. Its uninsured subcontractor rule requires a certificate of insurance for the subcontractor’s workers’ comp. Without one, the auditor uses the subcontractor’s payroll records if they are complete. Otherwise the auditor counts the full subcontract price, or, when the job’s paperwork shows part of the price as pay, that part with a floor of 90 percent of the price for labor-only work. Hired vehicles with drivers have their own rule: the drivers’ payroll counts in full, and when it cannot be obtained, or the driver is an owner-operator without a set wage, one third of the contract price counts as payroll. If you supplied fuel or maintenance outside that price, its value is added first. The added payroll goes into the class the person would have had as your employee, and your experience mod applies.

Example: $90,000 paid to three contract drivers

This example uses a made-up rate of $5.00 per $100 of payroll to show the math. Say you paid three drivers a total of $90,000 during the policy year, and none of them gave you a workers’ comp certificate.

Florida’s statute points auditors to the same records. Its audits must cover every kind of payment, to independent contractors and subcontractors as well as employees, and they rely on the certificates of insurance subcontractors keep. Collect a certificate before a contract driver’s first trip, confirm its policy period spans every week they drive for you, and file it with your 1099 records.

Payroll the auditor counts, and what stays out

Workers’ comp payroll counts more than base wages. North Carolina’s manual, as one state’s example, includes commissions, bonuses, holiday, vacation and sick pay, and pay put into employee-elected plans. Virginia’s guide lists holiday, vacation, and sick pay the same way.

Some pay comes out, but only with records that show it:

1. Overtime premium. Only the extra part of overtime pay is excluded, and only when your records show overtime separately by employee and in summary by class. If you record regular and overtime pay together at time and a half, the manual lets you exclude one third of that total.
2. Tips. Tips the rider or family chooses to give are excluded. The tipping guide covers whether drivers may accept them at all.
3. Mileage and expense reimbursements. Excluded when records show a real business expense, listed apart from wages, at roughly actual cost. The manual’s own example treats mileage at a fair per-mile rate as excluded.
4. Officers and owners. Executive officers are rated within a minimum and maximum payroll the manual sets. LLC members and sole proprietors are outside coverage unless they elect it.

Split roles follow strict rules. North Carolina’s manual lets one employee’s payroll be divided between two classes only when your records show the actual payroll and time in each, and it forbids estimated or percentage splits. Without those records, the whole payroll for that person goes to the highest-rated class that applies. Code 8810, clerical office employees, is never available for a split, so a dispatcher who also drives cannot move part of that pay into the clerical rate.

Gross receipts and mileage on the auto policy

Some passenger carriers buy auto liability priced on receipts or miles instead of a charge per vehicle, and that policy is audited the way payroll is. IRMI describes the method as one used for taxis, buses, and other public autos, with gross receipts or mileage as the exposure base in place of the number of vehicles. You pay a deposit on your estimate, and the standard auto form’s audit condition sets the final premium once the insurer knows the real figure.

Two definitions in the policy decide how big that final bill gets, so ask for both in writing before binding:

• What counts as receipts. Billed or collected. If the policy counts what you billed, trips a broker denied or never paid still add premium, so keep a payer-by-payer revenue report that ties to your books and shows denials separately.
• What counts as a mile. Loaded miles only, or every mile the van drives. If empty deadhead miles between trips count, your trip records need to show them, trip by trip, so the auditor is not left to estimate.

Records to have ready before the auditor calls

Pull these for the full policy period, not the calendar year:

• Payroll registers by employee, with overtime shown separately
• Quarterly federal and state payroll tax reports (Florida employers already send their quarterly state earnings reports to the carrier)
• Time records for anyone who works in more than one class
• 1099 totals by payee, with each contract driver’s certificate of insurance and its dates
• Revenue by payer from your general ledger, tied to the tax return
• The vehicle list with the date each van was added or removed
• Trip logs and mileage totals if the auto policy is rated on miles

Keep the auditor’s worksheet when the audit is done. You need it to check every line, and you need it to dispute one.

The stakes in one state: Florida

Florida’s workers’ comp statute shows how seriously states treat audits. Its rules must require an audit of every employer outside the construction class at least every two years, and may call for more frequent audits based on premium size, business type, or loss ratio. Refusing access when it stops the audit costs $500. An employer that denies reasonable access to payroll records can be charged up to three times its latest estimated annual premium. Understating or concealing payroll, or misrepresenting duties, carries a penalty of ten times the premium difference, and a false or incomplete application meant to cut premium is a third-degree felony.

How to dispute an audit result

Start with the insurer, in writing, within days of the bill. Ask for the audit worksheet, mark every line you dispute, and attach the record that proves your number: a certificate for a contract driver, an overtime report, a time study for a split-role employee.

If the insurer will not fix it, each state has its own next step:

• Florida. Section 627.371 lets you ask the insurer in writing to review how its rating plan was applied to you. Thirty days without a yes counts as a refusal, and that opens a written complaint to the Office of Insurance Regulation.
• Pennsylvania. The rating bureau hears appeals about how its rating rules were used on your policy, the class code assigned for example, while the policy runs and for twelve months after it ends. An appeal of the staff decision goes to a subcommittee of employer and insurer members within 30 days, and from there to the Insurance Commissioner, with 30 days to file after the subcommittee mails its decision.
• Virginia. The regulator’s guide says to complain to the agent or insurer first, by letter, then to the Bureau of Insurance.

Oregon’s 60-day deadline for workers’ comp premium disputes is in the workers’ comp guide. Whatever your state, missing a deadline can end the dispute, so calendar the deadline as soon as the bill arrives.

Making the next audit smaller

An audit bill is the gap between last year’s estimate and this year’s reality, so the fix is a better estimate. At renewal, give the agent this year’s real payroll by class, your contract driver totals, and your revenue run rate, and tell the insurer mid-term when a new broker contract adds drivers. Keep contract driver certificates current, split payroll records by class, and track overtime by employee. Your experience mod then works from accurate payroll, and the final bill holds no surprise.

Audit-ready trip records with HealthRide

HealthRide records every trip with its GPS miles and timestamps, keeps driver timecards, and exports the trip log as CSV or PDF. That gives the auditor trip counts, miles, and driver hours for the policy period without rebuilding them from paper. See reports for what each export includes.
