Description #

Audit Risk Indicators are warning signs that may suggest weaknesses in a carrier’s compliance program, reporting procedures, documentation practices, or recordkeeping systems. While the presence of a single risk indicator does not necessarily mean an audit will occur, multiple unresolved risk indicators often increase the likelihood of audit findings, tax assessments, penalties, and additional scrutiny from auditors.

Successful carriers actively monitor audit risk indicators throughout the year and take corrective action before filing quarterly returns. The earlier compliance issues are identified, the easier they are to correct.

Advanced IFTA provides several reporting and exception management tools specifically designed to help carriers identify and address audit risks before they become serious compliance problems.

Why Audit Risk Indicators Matter #

Audit risk indicators help carriers:

• Identify compliance weaknesses
• Reduce filing errors
• Improve documentation quality
• Strengthen audit readiness
• Improve reporting accuracy
• Reduce tax exposure
• Prevent recurring compliance issues
• Improve operational controls

Risk indicators serve as an early warning system for potential audit findings.
