Motor carrier audit

Motor carriers licensing vehicles through the International Registration Plan (IRP) and Wisconsin Interstate Fuel Tax Agreement (IFTA) must maintain individual vehicle distance records and supporting documents (drivers' daily logs, bills of lading, fuel receipts, etc.) to support the miles listed and fuel purchases claimed for these programs. These records are retained for five years and are subject to audit.

Records examinations verify the data reported.

• Billings or refunds are issued based on the audit findings and the program requirements for acceptable records.
• Other IRP and IFTA jurisdictions are informed of audit findings just as Wisconsin is informed of audits conducted by the other IRP and IFTA jurisdictions.

Carriers to be audited are picked randomly and also selected through information received from other sources.
