What Is a General Liability Insurance Audit? A Contractor Survival Guide

A few weeks after your policy year ends, an email arrives: your carrier wants to audit. New contractors panic; experienced contractors open a folder they have been maintaining all year and finish the whole thing in an afternoon. This guide moves you from the first group to the second.

Why Audits Exist

General liability and workers’ comp premiums are based on estimates – projected payroll, revenue, and subcontractor costs made at the start of the term. The audit compares estimates to reality and adjusts the premium in whichever direction the numbers point. Grew faster than projected? Expect an additional bill. Slow year? Money comes back. The audit itself is neutral; preparation determines whether it feels that way.

What the Auditor Reviews

• Payroll records – quarterly tax filings, W-2s, and payroll journals, ideally separated by employee duty.
• Revenue figures – sales by operation type, since different work can be rated differently.
• Cash disbursements and 1099s – the auditor is hunting for payments to individuals and subs.
• Certificates of insurance for every subcontractor – the single most consequential folder in the review.
• Descriptions of operations – what you actually did this year, which drives classification.

The Uninsured Sub Trap (Again)

It bears repeating because it generates more audit pain than everything else combined: payments to subcontractors without certificates on file are typically treated as your payroll and charged at your rates. A $150,000 payment to an uninsured framing sub can add thousands to your audit bill in one line item. The fix costs nothing: collect a current certificate before every sub starts, and store it where audit-you can find it.

How to Prepare All Year (In About an Hour Per Month)

1. Keep a running folder – digital is fine – of sub certificates with policy dates.
2. Book payroll by duty: field, office, sales, owners.
3. Track revenue by type of work if you operate in multiple classes.
4. When you land unusually large or unusual projects, tell your agent mid-term – adjusting the estimate beats a shock audit.

If the Audit Bill Looks Wrong

Audits contain errors more often than the industry admits – misapplied class codes, double-counted payroll, certificates ignored. You have the right to dispute. Request the auditor’s worksheets, match them against your records, and route the dispute through your agent, who speaks the dialect. Do not simply pay a number that does not reconcile – and do not ignore it either, since unpaid audits become cancellations and collections.

The Mindset Shift

Contractors who treat the audit as a year-round bookkeeping habit rather than an annual ambush consistently pay less – not through tricks, but because accurate records are almost always cheaper than the assumptions auditors make when records are missing.

The Mid-Term Adjustment: Your Pressure Valve

Audits sting hardest when reality drifted far from estimates – so do not let it drift silently. Land a contract that doubles your year? Add a crew in March? Call your agent and adjust the exposure basis mid-term. Premiums true up gradually instead of arriving as one year-end invoice, and carriers respect accounts that self-report growth. The same valve works downward: a slow year reported early can reduce installments now rather than waiting for a return premium later. The audit should confirm what your carrier already knows – never reveal it.

Frequently Asked Questions About Premium Audits

What happens if I ignore the audit request?

Non-compliance triggers estimated audits – carriers bill assuming the worst – plus potential cancellation and flags that follow you to the next application. Auditors are easier to satisfy than to avoid; respond promptly even when busy season argues otherwise.

Are audits done in person or online?

Small accounts commonly complete mail or portal audits with uploaded records; larger or higher-hazard accounts get phone or field audits. The records list is the same either way – preparation, not format, determines the outcome.

Can the audit lower my premium?

Absolutely – overestimated payroll or revenue produces return premium. Contractors who conservatively estimate at binding and true up at audit are financing their carrier interest-free in reverse; realistic estimates serve cash flow best.

How long after expiration can the carrier audit?

Policies grant audit rights for a period after expiration – commonly up to three years. Keep payroll records, sub certificates, and job cost data organized at least that long; the folder you kept is the dispute you never have.

Do audits apply to my liability policy or just workers’ comp?

Both, when premium is exposure-based. General liability audits review revenue, payroll, and subcontractor costs; comp audits focus on payroll by class. Same folder, two audiences – one more reason the records habit pays twice.
