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.

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. Auto-generate your IFTA return

Frequently asked questions

How often do I file IFTA?

Quarterly. Returns are due by the last day of the month following each quarter (Apr 30, Jul 31, Oct 31, Jan 31).

Do I need IFTA if I only drive in one state?

No — IFTA only applies if you cross jurisdictions in a qualified motor vehicle (over 26,000 lbs GVW or 3+ axles).
