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 - combined with the 4% IFTA audit minimum, most multi-state carriers will see an IRP and an IFTA audit within a 5-year window. Source documents must be retained for the current registration year plus three preceding years (four years total) under IRP §1015.
