    IFTA Quarterly Filing: A No-Stress Walkthrough for Small Fleets

    IFTA isn't hard — it's tedious. Miss one fuel receipt or mis-allocate one state's miles and you'll trigger a desk audit that costs more time than the tax itself. Here's the workflow we coach customers through.

    IFTA Quarterly Filing: A No-Stress Walkthrough for Small Fleets — Rigmatix trucking management software

    What IFTA actually is

    The International Fuel Tax Agreement consolidates fuel tax reporting across all 48 contiguous U.S. states and 10 Canadian provinces. You file in your base jurisdiction once per quarter and the system reconciles what you owe (or are refunded) in every other state you drove through.

    The four numbers per state that decide your return

    • Total taxable miles in the jurisdiction
    • Total non-taxable miles (off-highway, fuel trip permits)
    • Total gallons purchased in the jurisdiction (with receipts)
    • MPG across the fleet — calculated, not estimated

    The 5 mistakes that trigger audits

    • Mileage that doesn't match ELD records
    • Fuel receipts missing the state or gallon count
    • Personal conveyance miles counted as taxable
    • Forgetting to file a zero-mile return for a quiet quarter
    • Hand-keyed odometer readings that drift from GPS

    How to file in under 20 minutes

    Pull GPS miles per state from your TMS, pull fuel purchases from your card export, drop both into the IFTA module, review the per-state breakdown, e-file with your base state. Done.
