IFTA Record Retention Questions

Record retention can be jurisdiction-specific. This page frames what to verify rather than stating a universal rule.

Last reviewed: 2026-05-25 Reviewed against current official sources by the TruckTaxHub editorial team Retention periods vary by base jurisdiction; verify current requirements directly with your IFTA licensing jurisdiction

Questions to verify

  • How long records must be kept
  • Which records are required
  • Accepted electronic formats
  • What happens after a base jurisdiction change

Conservative habit

Keep filed returns, mileage support, fuel records, and correspondence together by quarter.

Source-gated note

Use your base jurisdiction's current guidance for the specific retention period and audit documentation requirements.

Keep the record set, not only the return

The filed return shows what was reported, but the support explains why it was reported that way. Retain the source mileage records, fuel records, worksheets, payment confirmations, amendment notes, and correspondence together. A saved return without the records behind it is weak support if the quarter is reviewed later.

Retention file naming

  • Use quarter and year in every folder name
  • Separate mileage, fuel, filed returns, payments, and correspondence
  • Keep old base jurisdiction records under the jurisdiction that accepted the filing
  • Avoid relying on screenshots when a PDF or CSV export is available

Do not purge right after changing systems

A new ELD, fuel card, accountant, or base jurisdiction is a reason to export old records, not delete them. Portal access often changes when an account is closed, a truck is sold, or a provider contract ends.

Retention calendar

Add a destroy-after review date only after checking the base jurisdiction's current retention rule. If the account was audited, amended, or transferred, keep the records longer until the open issue is closed.

FAQ

Is this IFTA record retention information tax advice?

No. It is general educational information. Trucking businesses should confirm current rules and discuss their facts with a qualified tax professional.

Can I keep IFTA records digitally instead of paper?

Most IFTA base jurisdictions accept electronic records, but the format and accessibility requirements vary. A common requirement is that electronic records must be retrievable and readable during an audit — meaning a folder of downloaded PDFs and CSV exports generally satisfies the requirement, while records locked in a portal login that expires may not. Check your base jurisdiction's current guidance on acceptable electronic formats. As a practical matter, saving quarterly folders with named files (Q1-2025-fuel-card.csv, Q1-2025-mileage-export.pdf) is far more reliable than planning to log back into a portal years later.

What happens to my IFTA records if I change base jurisdictions?

When you transfer your IFTA account to a new base jurisdiction, your obligations under the old jurisdiction don't automatically disappear. Returns filed with the previous base jurisdiction remain subject to that jurisdiction's audit authority for the retention period that applied when those returns were filed. Keep records from the old jurisdiction's period as if the audit window hasn't closed — don't delete records just because the account moved. Contact both jurisdictions if you have questions about overlapping obligations during a transition.
