x3allamerican IFTA Audit Preparation
IFTA audits occur every 3-5 years for active carriers. Preparation determines outcome — penalties are usually small if records are complete; large if records are missing.
When you're selected
- Letter from base state's DOR/DMV
- Typically 30 days notice
- May target specific tax year(s)
- Quote: "We will examine your records for IFTA reporting accuracy."
Records to produce
- Quarterly IFTA returns for the audit period (you already filed these)
- Fuel receipts (every purchase, by date + state)
- Mileage records (state-by-state breakdown)
- Vehicle records (VINs, license plates, gross weight)
- Trip sheets if used (driver-recorded journey data)
- ELD or GPS data if available
- Tax-paid fuel logs for tax-paid purchases
Audit procedure
- Initial meeting: explanation of scope + records request
- Records review: auditor examines your filings + supporting docs
- Sample selection: typically 3-12 months sampled in detail
- Reconciliation: comparing your reported miles vs records (ELD + GPS)
- Findings: discrepancies identified
- Determination: refund OR additional tax owed (interest + penalty)
Common audit findings
- Reported miles vs actual miles mismatch
- Fuel receipts missing or duplicated
- Tax-paid fuel inadvertently double-counted
- Personal use miles included in IFTA reporting
- Out-of-route miles unaccounted
Typical penalties
- No errors: no penalty (rare)
- Minor errors (< 5% variance): warning + correction
- Significant errors (5-20% variance): additional tax + interest
- Egregious errors or fraud: tax + interest + penalty (10-50%)
- Criminal: very rare, but possible for intentional fraud
How to prepare proactively
- Maintain quarterly IFTA reconciliation (don't wait for audit)
- Keep receipts organized by date and state
- Verify mileage from ELD against fuel receipts
- Address fuel card discrepancies immediately
- Save all trip-by-trip records for 4 years (IFTA requires 4-year retention)
