IRP Audit

Definition

An IRP audit is the periodic compliance review the base jurisdiction performs on IRP registrants under the IRP Audit Manual. Auditors verify mileage reported by jurisdiction against driver trip records, ELD logs, fuel receipts, and dispatch documents. Findings result in retroactive fee adjustments, penalties, and interest. Each IRP jurisdiction must audit at least 3% of its registrants annually. Source documents must be retained for the current registration year plus three preceding years (four years total) under IRP §1015.
