Description #
Annual Audit Review Procedures represent the highest level of compliance review within an IFTA program. While monthly and quarterly reviews focus on identifying and correcting operational issues, the annual review evaluates the entire year’s reporting activity to ensure complete audit readiness.
The annual review serves as a comprehensive compliance assessment covering mileage records, fuel purchases, filings, vehicle activity, exception reports, adjustments, and supporting documentation. The objective is to verify that all records necessary to support an audit are complete, accurate, organized, and readily accessible.
Carriers that perform annual reviews are significantly better prepared for audits and are more likely to identify recurring issues before they become costly compliance problems.
Why Annual Reviews Matter #
Annual reviews help carriers:
- Improve audit readiness
- Verify record retention compliance
- Identify recurring compliance issues
- Validate annual reporting accuracy
- Reduce future audit risk
- Improve operational controls
- Strengthen documentation practices
- Prepare for potential audits
An annual review should be conducted after the completion of the fourth quarter and before the start of the next reporting year.
