IFTA Fuel Tax Calculator — 2025 (All Quarters)

“All Fuels” shows each fuel type in its own table. Picking a single fuel shows only that fuel.

Grand Net Tax: —

Step 2 — Add Trip Rows (Fill left → right)

CSV order: date, truck, jurisdiction, miles, fuel, notes[, fuelType]
Fuel Type must match the actual fuel used for that row. Jurisdiction uses two-letter codes (e.g., IL, ON). Enter distance driven within that jurisdiction and fuel purchased within that jurisdiction.
Date Truck Fuel Type ? Jurisdiction ? Distance Fuel Notes
Format: YYYY-MM-DD Unit # (e.g., 1203) Pick the fuel used on this leg e.g., IL, IN, OH, ON, QC Miles/KM driven in this jurisdiction only Gallons/Liters purchased in this jurisdiction Optional: route, BOL, PO, stop, etc.

Step 3 — Review Summary & Enter Rates (by Fuel)

For each fuel type: Fleet MPG = Miles ÷ Gallons (for that fuel). Taxable Gal = Jur Miles ÷ Fleet MPG for that fuel. Net = (Taxable − Tax-Paid) × Rate. For CNG/LNG, enter GGE/DGE-equivalent rates if required by the jurisdiction.
