How to Track IFTA Miles by State and Province
Build a trip-level distance record that can be totaled by jurisdiction and traced back to source data.

Key answer
Track IFTA miles at the trip level, then total the distance traveled in every state or province for the quarter. Keep trip dates, origin, destination, route, odometer or ECM readings, total trip distance, jurisdiction distance, and vehicle ID. Reconcile jurisdiction totals to the fleet total and retain the underlying fuel and distance records for at least four years.
What IFTA miles should you record by state or province?
Record the actual distance each qualified vehicle travels in every IFTA jurisdiction, including the base jurisdiction. The working record should start with each trip, not with an estimated quarterly percentage.
IFTA uses the word jurisdiction because the agreement covers participating U.S. states and Canadian provinces. Your quarterly summary should show each jurisdiction separately and reconcile to total fleet distance for the same reporting period.
Which details belong in an IFTA distance record?
The 2026 IFTA Procedures Manual, section P540.100, lists the core elements for records produced without a qualifying vehicle-tracking system. Capture them while the trip is fresh.
| Field | What to record |
|---|---|
| Trip dates | Beginning and ending dates |
| Locations | Origin, destination, and route of travel |
| Distance source | Beginning and ending odometer, hubodometer, ECM, or similar readings |
| Trip total | Total distance for the complete trip |
| Jurisdiction split | Distance traveled in each state or province |
| Vehicle | VIN or vehicle unit number |
How should GPS or ELD tracking data be stored?
A vehicle-tracking system can support the distance record, but the raw data still needs to be audit-ready. Under P540.200, a latitude-and-longitude record must be created at least every 10 minutes while the engine is on.
- Record the date and time of every system reading.
- Keep latitude and longitude to at least four decimal places.
- Include the ECM odometer reading, or acceptable trip-level odometer readings when ECM data is unavailable.
- Include the VIN or unit number.
- Export data in an auditable spreadsheet format such as XLS, XLSX, CSV, or delimited text.
The manual states that static-image formats such as PDF, JPEG, PNG, or Word are not acceptable as the vehicle-tracking data format. A screenshot may help explain a problem, but it is not a substitute for the underlying export.
How do you total jurisdiction miles for the quarter?
Sum the trip-level distance for each jurisdiction, then verify that the jurisdiction totals equal the fleet total for the same cut-off period.
Quarterly fleet miles = sum of all jurisdiction miles
Reconciliation difference = fleet miles minus sum of jurisdiction miles. The target is zero.
| Jurisdiction | Miles |
|---|---|
| Tennessee | 118 |
| Kentucky | 172 |
| Ohio | 96 |
| Trip total | 386 |
In this example, 118 + 172 + 96 equals the 386-mile trip total, so the trip reconciles. Repeat the same check after combining every trip in the quarter.
What records should support the mileage totals?
Keep the distance source and the related fuel records together. IFTA auditors evaluate whether the quantity and quality of the records are sufficient to verify reported distance and fuel.
- Trip sheets, dispatch records, bills of lading, and route records.
- Odometer, hubodometer, ECM, GPS, or ELD source data used for the calculation.
- Quarterly jurisdiction summaries and the reconciliation to total fleet miles.
- Fuel receipts, invoices, card statements, or valid digital transaction records.
- Notes explaining route changes, missing data, manual corrections, or unusual differences.
For a broader expense workflow, use the trucking expense tracker guide. To connect mileage with revenue, use the rate-per-mile guide.
How long do IFTA records need to be retained?
The 2026 IFTA Procedures Manual, section P510, requires a licensee to retain applicable records for four years after the return was due or filed, whichever is later. Waivers, jeopardy assessments, an audit, or a refund request can extend the practical retention period.
Make records accessible to the base jurisdiction. If you change systems, preserve readable exports and the mapping needed to understand them rather than keeping only a login to an old service.
What happens when IFTA records are inadequate?
Inadequate records can lead the base jurisdiction to use the best information available and apply audit adjustments. Section P570 also allows specified additional assessments when fleet records do not meet the adequacy standard or no records are produced after a written demand.
Do not repair a gap by inventing a route or spreading miles with an unsupported percentage. Document the gap, preserve the remaining source records, and ask the base jurisdiction or a qualified IFTA professional how to correct the filing.
Which official IFTA sources should you verify?
Use the current manual and your base jurisdiction instructions before filing. The source links below were reviewed on August 3, 2026.
