Before an audit starts

Preparation is easier when records are maintained during the quarter, not rebuilt under deadline pressure. Confirm you can produce complete records for each quarter under review.

Mileage records to verify

  • Trip list with dates and vehicle unit numbers
  • Origin, destination, and route detail
  • Jurisdiction miles that sum to quarterly totals
  • Odometer readings or documented distance method
  • Explanation for large mileage adjustments

Fuel records to verify

  • Fuel receipts or invoices with date and location
  • Gallons and fuel type for each purchase
  • Tax-paid gallons summarized by jurisdiction
  • Matching between fuel logs and receipts

Quarterly returns and supporting totals

  • Filed IFTA returns for each quarter requested
  • Proof of payment where applicable
  • Worksheets or software exports supporting jurisdiction miles and gallons
  • Consistent fleet MPG across supporting detail

Common audit gaps

  • Missing receipts for reported tax-paid gallons
  • Trip detail that does not support jurisdiction mileage totals
  • Gaps in dates during active operating periods
  • Personal miles included in IFTA totals
  • Manual spreadsheet errors across jurisdictions

How IFTAfy supports audit readiness
