ELD location data and IFTA distance records can overlap, but one export should not be assumed to satisfy every IFTA recordkeeping need. Reconcile jurisdictional miles, vehicle identity, trip continuity, fuel documents, edits, and gaps under the fleet's IFTA procedures.
What this means for your fleet
Run a monthly exception report that flags border crossings, missing position intervals, personal conveyance, yard moves, vehicle swaps, unit changes, and unexplained differences between trip and tax systems.
Monthly IFTA reconciliation example
A truck’s ELD export shows 8,240 total miles while the tax worksheet totals 8,115 jurisdictional miles. The reviewer does not force the totals to match. They identify a device replacement, 82 miles recorded before the new unit mapping became effective, 31 miles in a GPS gap supported by dispatch and odometer records, and a 12-mile unit-conversion error. The corrected worksheet retains each adjustment and source instead of altering the ELD history.
Use the ELD for timestamped vehicle/location inputs only to the extent the export supports them. Confirm Factor’s current jurisdiction report, field definitions, edit handling, and plan inclusion before describing it as IFTA-ready.
What to check
Use these checks before changing a log, policy, device, integration, or buying decision.
| Check | How to verify |
|---|---|
| 1. Confirm vehicle and unit identity | Keep unit number, VIN, plate, device and reporting-account assignments across ELD and tax systems, effective dates, conflicts, and correction. |
| 2. Review jurisdiction boundaries | Trace one trip across timestamps and state lines; retain raw events, border method, gap, special-driving status, source files, and reviewer. |
| 3. Reconcile gaps and edits | Keep the jurisdiction-mile ledger, raw location intervals, missing/duplicate events, edits, unit conversion, variance calculation, reviewer, and resolution. |
| 4. Associate fuel documents | Retain each fuel record with vehicle, date/time, location, jurisdiction, quantity, source ID, duplicate check, exception, and reconciliation. |
| 5. Retain the calculation trail | Save source files and hashes, calculation version, rules, exclusions, corrections, reviewer, approval, exception list, and final output hash. |
Common failure modes
- Using odometer totals without jurisdiction detail.
- Silently filling GPS gaps.
- Mixing miles and kilometers.
Limits and exceptions
This guide does not decide a fact-specific legal exception, certify a record, or guarantee a compliance, safety, cost, or audit outcome. Keep the original ELD record and any edit history. Use the current official rule for applicability and the exact installed-device manual for screen-by-screen actions.

Reconcile the same trip across systems
Bring one ELD day, dispatch record, vehicle record, and tax or safety output so field and timestamp differences can be tested. Factor ELD can demonstrate its current product; rule applicability remains a fleet compliance decision.
