Miles Driven & Fuel Purchased — Per State
Add every state you drove through this quarter
How to fill this in: For every state you drove through this quarter, enter:
(1) Miles Driven — total miles in that state (from GPS, logbook, or odometer notes)
(2) Gallons Purchased — gallons of fuel you actually bought in that state (from receipts). Enter 0 if you drove through but didn't fuel up there.
⚠️ Same state entered twice — each state should appear only once per quarter.

    * Gallons Consumed = Miles Driven ÷ Fleet MPG. This is how many gallons IFTA says you should have used in that state based on your driving distance.

    How IFTA Tax Is Calculated — The Official 4-Step Formula
    1

    Calculate Fleet MPG

    Total Miles Driven ÷ Total Gallons Purchased = Your fleet's average fuel efficiency for the quarter. This single number governs all state calculations.

    2

    Gallons Consumed Per State

    State Miles ÷ Fleet MPG = How many gallons IFTA says you used in that state. This is calculated, not measured — based on how far you drove there.

    3

    Net Taxable Gallons

    Gallons Consumed − Gallons Purchased = The net difference. Positive means you owe tax. Negative means that state owes you a credit.

    4

    Tax Due or Credit

    Net Taxable Gallons × State Tax Rate = Tax owed or credit earned per state. All results are totaled for your net quarterly payment or refund.

    IFTA Formulas

    ①Fleet MPG = Total Miles ÷ Total Gallons Purchased
    ②Gallons Consumed [state] = State Miles ÷ Fleet MPG
    ③Net Taxable Gal. = Gallons Consumed − Tax-Paid Gallons Purchased
    ④Tax Due = Net Taxable Gal. × State Tax Rate
    ⑤Surcharge = Total Taxable Gallons × Surcharge Rate  (KY, VA, NY, NM only — always owed)
    Important about surcharge states: Kentucky (2.0¢), Virginia (6.5¢), New York (0.95¢), and New Mexico (1.0¢) calculate surcharges on total taxable gallons consumed — not net taxable gallons. This means these surcharges are always owed and never generate credits, even if you purchased excess fuel in those states.

    What Is IFTA and How Does It Work?

    The International Fuel Tax Agreement (IFTA) is an agreement between 48 US states and 10 Canadian provinces that simplifies fuel tax reporting for commercial motor carriers. Before IFTA, truckers had to file separate fuel tax returns in every state they drove through — a major administrative burden. IFTA replaced that system with a single quarterly filing submitted to your home base state.

    Under IFTA, every qualifying carrier receives a license and two annual decals. Each quarter, they report total miles driven and total fuel purchased in each jurisdiction. The base state then distributes fuel tax payments to the appropriate states based on where the miles were actually driven versus where fuel was purchased.

    Frequently Asked Questions — IFTA

    What is IFTA and who must file?+
    IFTA (International Fuel Tax Agreement) covers 48 US states and 10 Canadian provinces. You must file if your commercial vehicle operates in 2+ jurisdictions AND weighs over 26,000 lbs, has 3+ axles, or carries 20+ passengers for hire. Alaska, Hawaii, and DC are not IFTA members.
    Why do I get a credit in some states?+
    If you purchased more fuel in a state than you consumed there (based on miles driven ÷ fleet MPG), you pre-paid more fuel tax than you owed. That surplus becomes a credit that offsets taxes owed in states where you drove more than you fueled. This is the core mechanic of IFTA — fuel taxes follow the miles, not the fuel pump.
    What is the late IFTA filing penalty?+
    The penalty is $50 OR 10% of your net tax liability — whichever amount is greater. Monthly interest also accrues on unpaid balances. Crucially, even if you drove zero miles in a quarter, you must still file a zero-activity return. Missing a filing always triggers the minimum $50 penalty.
    How accurate is this calculator?+
    This calculator uses the exact official 4-step IFTA calculation methodology from the IFTA Articles of Agreement, with Q1 2026 rates sourced directly from the IFTA, Inc. tax rate matrix. Results are highly accurate for standard diesel and gasoline calculations. Rates change quarterly — always verify at iftach.org before filing your official return.
    What are surcharge states?+
    Kentucky (2.0¢/gal), Virginia (6.5¢/gal), New York (0.95¢/gal), and New Mexico (1.0¢/gal) impose surcharges on top of their base IFTA rate. Unlike regular fuel tax, surcharges are calculated on total taxable gallons consumed — not net taxable gallons. This means you always owe the surcharge in these states regardless of how much fuel you purchased there.
    Does Oregon charge IFTA fuel tax?+
    Oregon uses a weight-mile tax instead of per-gallon fuel tax. The IFTA diesel rate for Oregon is $0.00 — you report Oregon miles but owe no IFTA fuel tax there. Oregon's separate weight-mile tax must be filed directly with the Oregon Department of Transportation through their Weight-Mile Tax program.
    Can I use this calculator for Canadian provinces?+
    Yes — all 10 IFTA Canadian provinces are included: Ontario, Quebec, British Columbia, Alberta, Manitoba, Saskatchewan, Nova Scotia, New Brunswick, Newfoundland, and Prince Edward Island. For accurate filing involving Canadian provinces, note that rates involve CAD/USD currency conversion and kilometers must be converted to miles. Consult your base state or a tax professional for cross-border filings.
    How long must I keep IFTA records?+
    IFTA requires you to keep all records supporting your quarterly returns for a minimum of 4 years. This includes fuel receipts (showing date, location, gallons, and price), mileage records per state (GPS logs, trip sheets, or odometer readings at state borders), and copies of all IFTA returns filed. States can audit any return within that 4-year window.

    Tips to Reduce Your IFTA Tax

    ⛽ Fuel Strategically

    Buy extra fuel in low-tax states (Mississippi $0.18, Oklahoma $0.19, Texas $0.20) before entering high-tax states like Pennsylvania ($0.74) or Indiana ($0.54). Same miles, but more tax-paid credits in your favor.

    📍 Track Miles Accurately

    Use GPS that logs miles by state automatically. Manual estimates are a top audit trigger. Accurate state mileage also ensures you're claiming every credit you're entitled to.

    📅 Never Miss a Deadline

    The $50 minimum applies even if you owe zero tax. File a zero-activity return every quarter you hold an IFTA license, even if you didn't cross state lines that quarter.
