ClassCheck checks your workers' compensation premium audit for class-code misclassification โ the most expensive error on a small business's comp policy.
Your premium is priced off NCCI job classification codes, and rates differ by 100x or more between them: clerical work runs about $0.05โ$0.35 per $100 of payroll, roofing $15โ$45. NCCI's own classification inspection data found governing-code changes on more than 60% of inspected files for the two most commonly misclassified codes. Overcharges are typically recoverable retroactively for around 3 years.
Free checker, no signup. Describe what each employee actually does and the class code currently assigned to their payroll. ClassCheck compares each role against known NCCI classification patterns, flags suspect codes with a confidence level, estimates the overcharge, and tells you what to argue. About two minutes with your policy declarations page or audit worksheet.
Full Audit Review โ $249 flat. Send your real audit worksheet and payroll report and get a line-by-line review of every class code, a written dispute letter pack, and plain-English filing instructions for your carrier or state bureau โ within 3 business days. Every review is checked by a person before delivery, and it is refunded in full if we find nothing worth disputing.
Also free: a class-code reference library, state-by-state guides, and articles on audit disputes, owner/officer payroll caps, the overtime straight-time rule, and the clerical standard exception.
Coverage: NCCI states โ roughly 35+ states plus DC. States with an independent rating bureau or a monopolistic state fund are not supported yet.
ClassCheck provides self-advocacy information only. It is not legal, insurance, or accounting advice, and there is no guaranteed outcome.

ClassCheck works on the policyholder's side of a workers' comp premium audit that has already landed on your desk.
It checks the one thing that actually sets the premium โ the NCCI class code assigned to each employee's payroll. You describe what each person really does and enter the code currently charged; ClassCheck compares that against known classification patterns, flags codes that conflict, gives a confidence level for each flag, and estimates what the error is costing you.
Two things are unusual about it: it is free with no signup and no sales call, and it is deliberately conservative โ a code is only flagged when the duties genuinely conflict with a known classification pattern, because a false alarm sends a business owner into a dispute they cannot win.
The established way to get this checked is a premium recovery consultant. They do good work, but they take 30โ50% of what they recover on contingency and generally will not open a file under roughly $100k in annual premium โ which leaves several hundred thousand small employers with nobody looking at their codes.
ClassCheck covers that gap:
And unlike workers' comp platforms that bundle payroll or sell the policy itself, ClassCheck is not selling you insurance โ it only audits the classification you have already been charged for.
US small business owners who have just received a workers' comp premium audit and think the number looks wrong.
In practice that means payroll-heavy, mixed-duty businesses in NCCI states โ contractors and trades, restaurants, auto shops, landscapers, small manufacturers โ usually 3โ50 employees, where a single misclassified office manager or working owner is worth thousands of dollars a year.
The second audience is the people who read these audits on a client's behalf: bookkeepers, accountants and independent agents who want a fast sanity check before escalating to the carrier.
It came out of NCCI's own classification inspection data: for the two most commonly misclassified codes, more than 60% of inspected files ended up with a different governing classification.
That matters because the code is the price. Rates differ by 100x or more between class codes โ clerical work runs about $0.05โ$0.35 per $100 of payroll, roofing $15โ$45. A clerk left in a roofing code costs that employer thousands a year, and the overcharge is typically recoverable around 3 years back.
Carriers already run software across these files. Policyholders had nothing, and the consultants who fix this ignore small accounts. ClassCheck was built in July 2026 to give the small end of the market a way to check its own codes before accepting the bill.
