IFTA quarterly is a paperwork tax on top of the fuel tax. iMatrix replaces the spreadsheet — multi-GNSS positions from FC-501 cross-reference fuel-rate SPNs from the same gateway, jurisdictional miles roll up automatically, and the export drops in the format your filing software expects.
FC-501 reports GNSS positions every check-in. Cloud snaps each segment to a US state, Canadian province, or Mexican estado — taxable miles, non-taxable miles, and off-highway miles separated.
Total gallons consumed read from J1939 SPN 250 (engine fuel total). No reliance on receipts the driver may have lost; the engine itself is the witness.
One click pulls the quarter's miles and gallons by jurisdiction, formatted for IFTA-1A and the major filing services. CSV, PDF, or direct integration.
IFTA filing is GPS + fuel. But when an auditor asks "where was this load between Reno and Salt Lake City?" the cargo conditions and door events are the audit trail that backs the mileage claim.
Concurrent GPS / GLONASS / BeiDou / Galileo positioning every check-in. Reads SPN 250 fuel-total continuously. Crossing-state events are auto-detected — no driver action required.
Cargo temperature alongside mileage. If the load was reefer or HAZMAT, the IFTA record carries the matching environmental log — useful for state DOT audits that look at more than miles.
Door open/close events at fuel and rest stops. When the IFTA spreadsheet says "fueled in Wyoming," Sentry-1 confirms the trailer was actually opened there — protecting against driver mileage errors.
FC-501 reports GNSS, fuel total, and odometer on a configurable cadence. The default is 30 seconds at highway speed, longer when stationary.
iMatrix Cloud snaps each segment to its US state, Canadian province, or Mexican state boundary. Off-highway miles (yards, customer sites) excluded automatically.
Fuel total at each state-line crossing is differenced. Result: gallons consumed in each jurisdiction, with no reliance on driver fuel-receipt entry.
End of the quarter, click "IFTA Export." Pull a per-vehicle, per-jurisdiction roll-up in IFTA-1A format. Hand to the filing service or upload directly.
Multi-state operations file IFTA every quarter. Automated capture cuts the back-office work to minutes.
One truck, one IFTA filing — but the same paperwork. iMatrix produces the filing without a back office.
US/Canada/Mexico routes. Multi-GNSS handles every jurisdiction; eSIM stays connected through every border.
