    AmTrust Premium Audit

    We initially charge premium based upon estimated payroll at the beginning of the policy term. To ensure these figures are accurate and classifications are appropriate, all workers’ compensation policies are subject to an audit to determine actual premium.

    Audit Methods

    Physical - Audits are sent to a third-party firm to review the insured’s payroll information for the policy period, as well as their operations to verify their premium accurately reflects their coverage. The auditor will return their summary to us to complete the audit endorsement.

    If your policy is assigned for a physical on-site audit, you can expect to be contacted by our audit representative after your policy expires or is canceled.

    Mail Audit - A voluntary or mail audit is an audit completed by the insured using forms that are mailed to them, or you can complete these online. The insured must submit this summary and return it back to us along with payroll-supporting documents to complete the audit endorsement. It is different from a physical audit, which is completed by sending an auditor to the insured's location to complete the process for them in person.

    If your policy is assigned for a mail audit, you can expect to receive an audit form shortly after your policy expires or is canceled.
