Your IFTA quarter, worked out jurisdiction by jurisdiction
Log trip legs (date, unit, jurisdiction, total and taxable miles) and fuel purchases (gallons, cost, tax paid at the pump), paste this quarter's rates from the free official IFTA tax rate matrix, and the Return tab works out fleet MPG, taxable gallons, tax-paid gallons, net taxable gallons, tax and surcharge due or credit for every IFTA jurisdiction, plus the total. It warns you when a jurisdiction you drove or fuelled in has no rate entered, and the dashboard counts the days to the filing deadline.
Example file: 2 trucks, one made-up quarter (Q3 2026), 193 trip legs, 48 fuel buys

How it works
- Set the quarter, then paste this quarter's rates for the jurisdictions you drove in from iftach.org (Tax Rate Matrix).
- Enter trip legs on Miles and fuel purchases on Fuel (or paste them from your logs).
- Copy the Return lines into your base jurisdiction's IFTA return and file there.
FAQ
Why not IFTAplus or other IFTA software?
IFTA apps add GPS mileage and filing help, at $4.99/month and up (IFTAplus), $19/month (FleetCollect Solo) or $145/month in a TMS (TenTrucks). If you already keep trip sheets and fuel receipts, Fuelfern does the quarterly maths for $19 once.
Are the tax rates included?
No. They change every quarter and IFTA, Inc. doesn't allow redistribution. Download the free matrix at iftach.org and enter the rates for the jurisdictions you drove in; the Return flags any that are missing.
Does it file for me?
No. It prepares the numbers; you file the return with your base jurisdiction (most offer online filing).
Does it work in Google Sheets?
Yes: upload the .xlsx to Google Drive and open it with Google Sheets.
Is this tax advice?
No. It is a calculation worksheet; check each jurisdiction's rules (some exempt certain toll-road miles, for example).
