A fair way to handle fuel tax,
every mile, every quarter.
Miles split by state, official quarterly rates with surcharges, credit for every gallon you bought at the pump. This is the exact IFTA engine carriers run on the LoadWrap board, try it below.

IFTA Calculation Method
Route-Based (ZIP Coordinates)Miles in each jurisdiction calculated using ZIP coordinates and route analysis.
Gallons Consumed = Miles in State ÷ Fleet Average MPG
Tax Due = Gallons Consumed × State Tax Rate per gallon
Net = Tax Due - Tax Paid at pump. Positive = owe, Negative = credit.
Net Tax = (Miles ÷ MPG × Tax Rate) - (Gallons Purchased × Tax Rate)
What is IFTA?
The International Fuel Tax Agreement (IFTA) is a tax collection agreement among the 48 contiguous U.S. states and 10 Canadian provinces. It simplifies the reporting of fuel use taxes by motor carriers that operate in more than one jurisdiction.
One License
File one quarterly return with your base jurisdiction
58 Jurisdictions
48 U.S. states + 10 Canadian provinces
Quarterly Filing
Due last day of month following quarter end
Who Must File IFTA?
You must file IFTA if your vehicle meets ALL of the following criteria:
Vehicle has two axles and GVWR over 26,000 lbs, OR has three or more axles regardless of weight
Combined GVW/GCW exceeds 26,000 lbs
Travels in two or more IFTA jurisdictions
Used for commercial purposes (for-hire or business transport)
Step-by-Step IFTA Calculation
Calculate Total Miles per Jurisdiction
Track every mile driven in each state/province. Our system uses ZIP code coordinates to calculate route-based mileage distribution.
Total: 920 miles → IL: 168 mi, MO: 285 mi, OK: 187 mi, TX: 280 mi
Calculate Fleet Average MPG
Divide total miles by total gallons of fuel purchased during the quarter.
Example: 45,000 miles ÷ 7,500 gallons = 6.0 MPG
Calculate Gallons Consumed per Jurisdiction
Divide miles in each jurisdiction by your fleet average MPG.
Texas Example: 8,500 miles ÷ 6.0 MPG = 1,416.67 gallons consumed
Calculate Tax Due & Tax Paid per Jurisdiction
Multiply gallons by state tax rate to get tax amounts.
Tax Paid = Gallons Purchased in State × State Tax Rate
Texas: 1,416.67 gal × $0.20/gal = $283.33 tax due
Calculate Net Tax (Credit or Balance Due)
Subtract tax paid from tax due for each jurisdiction.
Negative = Credit (you get money back)
Positive = Balance Due (you owe taxes)
Filing Deadlines

Frequently Asked Questions
Everything owner-operators and fleets ask us about IFTA, answered straight.
Open the Calculator tab, type your pickup and delivery ZIP codes (or add states manually), enter your miles and the fuel you bought, and the engine splits everything by state and shows your net tax instantly. To keep what you calculate, register and create your free LoadWrap account: registered users save loads, file whole quarters, track every truck and export the filing-ready PDF.
Yes, and smart fleets plan around it. Every tax-paid gallon is a credit in the state where you bought it, so buying fuel in higher-rate states you actually drive through builds credits against what you owe there. The cheapest pump price is not always the cheapest gallon once the tax credit is counted. One exception: the Indiana, Kentucky and Virginia surcharge is owed no matter where you fuel. Run your route through this calculator with different fuel stops and compare the net.
Three steps. Fleet MPG = total miles divided by total gallons purchased. Taxable gallons per state = miles in that state divided by fleet MPG. Net tax per state = taxable gallons times the state rate, minus a credit for every tax-paid gallon you bought in that state. Negative means the state owes you a credit.
Indiana, Kentucky and Virginia add a surcharge on every gallon consumed in the state. Unlike the base rate, the surcharge gives no credit for fuel purchased there, it is always owed in full. This calculator itemizes the surcharge on its own line, exactly like the official return.
Yes. Rates refresh every quarter from the official IFTA matrix published at iftach.org. The engine currently runs Q2 2026 rates, the quarter being filed now, including all surcharges, with Q1 2026 available for late filings.
All 48 contiguous US states plus the 10 Canadian provinces, with provincial rates converted to USD per gallon. Alaska, Hawaii, D.C. and Mexico are not IFTA jurisdictions and are excluded automatically. Oregon shows a $0.00 IFTA rate because it charges a separate weight-mile tax instead.
Quarterly, on the last day of the month after the quarter ends: April 30, July 31, October 31 and January 31. If the deadline falls on a weekend or holiday it moves to the next business day. Filing late costs $50 or 10% of the tax due, whichever is greater, plus interest.
Four years of fuel receipts and mileage records. Receipts should show date, location, gallons, price and vehicle unit. Mileage records should show routes and miles per jurisdiction. LoadWrap accounts store receipts and per-state miles automatically, so an audit is a download, not a panic.
