Common IFTA mistakes
Missing a second filing (OR, KY, NM, NY, CT)
IFTA isn't the whole picture. Oregon runs weight-mile instead of IFTA fuel tax. Kentucky's KYU, New Mexico's WDT, New York's HUT, and Connecticut's HUF (new since 2023) are separate weight-distance filings for heavy trucks — missing one is the #1 source of penalty surprises.
Missing the surcharge states (IN, KY, VA)
Indiana, Kentucky, and Virginia charge a separate surcharge on top of the regular fuel tax — the portal lists them as two lines. Surcharges are owed on miles driven in those states, so you can't offset them by buying fuel there.
Skipping a zero-mileage return
Every IFTA state requires a return every quarter — even if you didn't run that quarter. Skipping one is the fastest way to a license suspension at the next scale house.
Logging DC, AK, or HI miles as IFTA
Washington DC, Alaska, and Hawaii are not IFTA jurisdictions. Miles run there are non-IFTA miles — don't lump them into a neighboring state's total.
Forgetting the state-line fuel stop
Pumped 40 gallons in Kingman AZ before crossing into California? That's an AZ purchase, not a CA one. Easy to miss when you're reconstructing months later from a pile of receipts.
Using rate-con miles instead of actual driven miles
The rate con says 847. You actually ran 912 because of a detour and a fuel stop off-route. IFTA wants what you drove, not what the broker planned — odometer or ELD miles are the right number.
Mailing paper in a state that requires e-file
Utah (since 2021), North Carolina, and Rhode Island (since April 2024) only accept electronic IFTA returns. A paper return in those states either gets rejected or incurs a penalty.
Mixing toll-road and regular miles
Certain turnpike miles in PA, OH, and NY aren't always taxable under IFTA. Lump them in and you're overpaying — or reporting inconsistently with what the state expects.
What is IFTA?
The International Fuel Tax Agreement (IFTA) is a tax agreement between the lower 48 US states and Canadian provinces. If you operate a qualified commercial motor vehicle in more than one jurisdiction, you file IFTA quarterly through your base state. The tax is based on how many miles you drove in each state versus how much fuel you purchased in each state — states you bought more fuel in than you drove through give you a credit, states you drove more than you fueled in owe tax.

What happens if you file late?
The baseline IFTA penalty is $50 or 10% of tax due, whichever is greater, on your return — one penalty per filing, not per state. On top of that, interest accrues per jurisdiction on any unpaid tax. Repeat late filers catch extra audit scrutiny and can have their IFTA license revoked, which means you can't legally cross state lines to run loads.
FAQ
Is this really free?+
Yes. One full calculation per IP and email, no catch. If you want to run it again next quarter you create a free account — past that, paid plans unlock the automation so you don't run it manually.
Do you file IFTA for me?+
No — you file through your base state's IFTA portal (your state DOR site or IFTA Clearinghouse). We prep the numbers and the PDF so the filing takes minutes instead of a weekend.
What if I only ran one state this quarter?+
You might not owe an IFTA filing at all. Lower 48 carriers that stayed inside a single jurisdiction the entire quarter are generally exempt until they cross a state line. Check with your base state — and if you're borderline, run the calc anyway so you have the record.
What about Oregon weight-mile, NY HUT, NM WDT, KY KYU, CT HUF?+
Those are separate state-level programs, not IFTA. Oregon weight-mile, NY HUT, NM WDT, KY KYU, and Connecticut HUF (new since 2023) all file on their own systems. This calculator is IFTA only — if you run in those states you file twice.
Will you sell my data?+
No — not to brokers, not to factoring companies, not to insurance, not to anybody. Your fuel receipts and miles are yours.
Can I use this every quarter for free?+
The free calc is one-time per IP/email. For quarterly filing without the scramble, that's what the paid app is for — Plaid bank sync, fuel-card import, Samsara ELD miles, daily accrual. Run it free this quarter, decide after.
Ready past just this quarter?
Free calc got you through Q1. Paid OTR gets you through every quarter after — automatically.
