Motor carrier IFTA and IRP record-keeping and audit
Motor carriers licensing vehicles through the International Registration Plan (IRP) and International Fuel Tax Agreement (IFTA) must maintain individual vehicle distance records and supporting documents (trip reports, drivers' daily logs, bills of lading, fuel receipts, etc.) to support the miles listed and fuel purchases claimed for these programs.
The carrier must use these records to complete the annual IRP registration renewal process, and to complete quarterly IFTA fuel tax report. The carrier must retain these records for six years and the records are subject to audit.
Audits verify the miles driven and fuel tax data that the carrier has 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.
We have sample record-keeping forms available. We are happy to assist you by answering questions about record-keeping requirements for IRP and IFTA motor vehicles.
