What is IFTA and How Do I Minimize Trucking Fuel Expenses?
Navigating the world of trucking gets complicated fast, and few areas trip up new operators like IFTA and fuel. What is IFTA, and how do you minimize trucking fuel expenses? They’re technically separate topics, but I found that to run efficiently, you have to manage them together as one system. Let’s break it down.
At the end, I’ll also cover something most fuel-savings articles won’t: how this whole picture changes when you run under FedEx Custom Critical the way our drivers at M2GT do. But first, the fundamentals every driver should understand.
What is IFTA?
IFTA is the International Fuel Tax Agreement, a cooperative pact between the 48 contiguous U.S. states and 10 Canadian provinces. It’s designed to simplify fuel tax reporting for motor carriers running across multiple jurisdictions.
Under IFTA, instead of filing separately in every state you drove through, you file a single fuel tax report each quarter that covers all the participating jurisdictions where your vehicles traveled. The goal is to make sure each jurisdiction gets its fair share of fuel tax revenue based on where the fuel was used, not where it was purchased.
That last point is the key to everything: IFTA is about where you burn the fuel, not where you buy it. Understanding that is the foundation of every fuel strategy below.
The Importance of Accurate Mileage and Fuel Tracking
Accurate mileage tracking is the heart of IFTA reporting. It determines how much fuel tax you owe each jurisdiction, and every mile counts. Small discrepancies add up to real money over time.
Tracking your fuel purchases matters just as much. It’s not only the total gallons you bought, but where you bought them. Because IFTA reconciles tax by where fuel is used against where it was purchased, sloppy fuel records lead straight to filing errors and potential audits.
The good news: your ELD does most of this for you. Most electronic logging devices track your miles by state automatically, and many let you log fuel receipts right in the app so your quarterly report is mostly built by the time filing comes around. I use Motive (formerly KeepTruckin), which handles both.
Quarterly Filing: Staying on Top of Your Reports
IFTA requires quarterly filings. Every three months, you submit a report showing your total miles driven in each state, total gallons purchased in each state, and the tax paid. It’s a lot of data, but it’s the basis for an accurate tax calculation, and your ELD software can generate most of it for you.
Don’t wait until the last minute. Updating your records regularly saves a lot of stress, and late filings bring penalties and interest. Staying current keeps you ahead of deadlines and out of trouble.
IFTA by State: Navigating Different Tax Rates
Here’s where it gets tricky. Each state sets its own fuel tax rate, and those rates can change every quarter. That means any specific rate you see published today, including any I mention below, is a snapshot that won’t stay current for long. Always verify the live rates for the quarter you’re filing.
Understanding how these rates work, though, is what lets you make smart fueling decisions. Which brings us to the single most useful fuel-buying concept most drivers never learn.
Fueling Strategy: Pre-Tax Price Is What Actually Matters
Choosing where to fuel is about far more than finding the nearest station or even the lowest pump price. The real number is the pre-tax price of the fuel.
Here’s why. Because IFTA settles up based on where you use fuel, the tax portion baked into the pump price essentially washes out at reconciliation. What doesn’t wash out is the base, pre-tax cost of the fuel itself. So a station in a high-tax state can actually be the cheaper place to buy, because its underlying fuel price is lower, even though the sticker price at the pump looks higher.
An illustration (numbers for example only, since IFTA rates change quarterly): imagine running I-10 from Alabama into Mississippi and Louisiana, where the state IFTA rates differ by several cents per gallon. If the pump price in the higher-tax state is only slightly higher but its pre-tax fuel cost is lower, that’s actually the cheaper fill once IFTA reconciles. The lesson isn’t the specific numbers, it’s the principle: compare pre-tax prices, not pump prices.
Pro tip: if you pay more in IFTA tax at the pump than you actually owe for miles run in that state, you can be refunded the overage. That’s exactly why the pre-tax price, not the sticker price, is what you optimize around.
Leveraging Technology: Fuelbook
Tools like Fuelbook make this practical. The app shows both the pre-tax and post-tax fuel prices at stations along your route, so you can actually see where the cheapest real fuel is instead of guessing from pump signs. Used alongside your fuel discount programs, it’s one of the simplest ways to stop leaving money at the pump.
Fuel Cards and Discount Programs
Fuel cards are one of the biggest levers on your fuel cost. Most fuel companies offer them to attract and keep customers, and they can knock real money off every gallon. The catch is that not all cards are created equal, and the discount gap between them is enormous.
To put that in perspective from my own experience: a typical branded fuel-chain card, like a Love’s card, might get you somewhere around $0.16 to $0.26 per gallon. That’s fine, but it’s a fraction of what a dedicated discount program delivers. Understanding that gap is what separates drivers who fuel smart from drivers who leave hundreds of dollars on the table every month.
A few things to know about fuel cards generally: they often come with short payment terms (frequently a week or less, which lets you run the load before the fuel bill is due), some charge monthly fees, and most are negotiable. If you can show you’re getting better prices elsewhere, many will match or beat it, so it’s worth carrying more than one and playing them against each other.
Greenlane — a Strong Option for Owner-Operators
Greenlane is a diesel discount program built specifically for truckers, and for owner-operators running their own authority, it’s genuinely worth a look. When I ran under my own authority, I used Greenlane and it delivered discounts in the same league as what I get now, often around $0.50 per gallon and up, which absolutely dwarfs a standard branded fuel-chain card.
A few things worth knowing: Greenlane runs on the EFS network and is accepted at thousands of discount locations nationwide, focused on the commercial diesel lanes where trucks fuel. Their model has evolved over time (it now centers on a prepaid “Diesel Wallet” you fund in advance, and it even has IFTA reporting built in), so confirm the current terms and payment structure directly with them before you sign up.
Full transparency: I don’t personally use Greenlane anymore, but not because anything’s wrong with it. I’ve moved to the FedEx Custom Critical fuel card, which I’ll explain next. For owner-operators who aren’t running under a carrier’s fuel program, Greenlane remains one of the better tools out there.
Fuel Rewards Programs
Beyond discounts, the major truck-stop chains run rewards programs worth signing up for, offering free showers, free drinks, weekly and monthly promotions, and points toward food and goods inside the store. Sign up for as many as you can, they’re free.
- Pilot / Flying J: My points, free showers, and free drinks always seemed to accrue fastest here, though prices aren’t always the best, so I still compare.
- TA / Petro: Huge locations, often with hundreds of free parking spots, food courts, and amenities. My favorite place to do a 34-hour reset on the road. (Fun fact: the Iowa 80, the world’s largest truck stop, is a TA/Petro.)
- Love’s: Many locations have dog parks, which is a big deal when you travel with a road dog like I do. Some also have Bojangles, an easy guilty pleasure on the road.
How This All Changes Under FedEx Custom Critical
Everything above is the owner-operator reality: you file your own IFTA, you shop your own fuel cards, you optimize your own pre-tax pricing. It’s real work, and doing it well is part of running a profitable operation.
But here’s the other side, and it’s a big reason a lot of drivers choose to run under an established carrier instead. When you drive under FedEx Custom Critical, the way our drivers at M2GT do, most of this simply gets handled for you:
- FedEx files your IFTA. That entire quarterly-filing burden this article just walked through? You don’t carry it. It’s done for you.
- You get a FedEx EFS fuel card with strong discounts, averaging around $0.50 per gallon and sometimes topping $1.00 per gallon, comparable to the best owner-op discount programs and far beyond a standard branded card.
- No out-of-pocket fuel. Funds are loaded onto your card when you pick up a load, so your fuel, DEF, and reefer fuel are covered. You’re not fronting hundreds of dollars in diesel and waiting to be made whole.
- No card fees.
That combination (someone else handling your fuel tax, deep per-gallon discounts, and no out-of-pocket fuel cost) removes most of the fuel-and-IFTA headache this whole article exists to help owner-operators manage. It’s the difference between running the system yourself and having the system run for you.
Conclusion
Minimizing fuel expenses isn’t about one trick, it’s about understanding how IFTA actually works, buying on pre-tax price instead of pump price, using the right discount tools, and keeping clean records. For owner-operators, mastering this is part of the job, and tools like Fuelbook and Greenlane make it very doable.
But it’s also worth knowing there’s an easier path. Running under FedEx Custom Critical takes the biggest pieces of this off your plate entirely, from IFTA filing to fuel discounts to never fronting the cost of a fill-up. If that sounds better than managing all of it yourself, that’s exactly the kind of thing we can walk you through.
If you’re weighing the owner-op path against running with an established carrier, our cost of getting your own authorityand how to get your own authority guides lay out the full picture, and our trucker tax deductions guide covers the write-offs that pair with all of this.
If you’re looking for a carrier that values compliance and treats its drivers right, schedule a call with M2GT and let’s talk about what we can offer you. You can also visit our Owner Operator page for more information.

Fueling Strategy: Pre-Tax Price Is What Actually Matters
Choosing where to fuel is about far more than finding the nearest station or even the lowest pump price. The real number is the pre-tax price of the fuel.
Here’s why, and it’s the part most drivers never get explained properly. With IFTA, each state collects fuel tax based on the miles you drove in that state, no matter where you actually bought your fuel. So say you fuel up entirely in Texas, where the state fuel tax is low, but you run through several surrounding states with higher rates. At the pump you paid Texas’s low tax, but when you file your quarterly IFTA, you settle up and pay the difference for all those higher-tax miles you drove elsewhere. The tax evens out either way.
What doesn’t even out is the pre-tax base price of the fuel itself. That’s the part you actually keep or lose. So a station in a higher-tax state can genuinely be the cheaper place to fuel, because if its pre-tax price is lower, you come out ahead at IFTA reconciliation even though the pump sticker looked higher. You pay a little more at the pump and get it back (and then some) when you file.
An illustration (numbers for example only, since IFTA rates change quarterly): if Texas fuel shows a lower pump price mostly because of a low state fuel tax, but a station in a higher-tax neighboring state has a lower pre-tax base price, that neighboring station is actually the cheaper fill once IFTA settles up. The lesson isn’t the specific states or numbers, it’s the principle: compare pre-tax prices, not pump prices.
Pro tip: if you pay more in fuel tax at the pump than you owe for the miles you actually ran in that state, the overage comes back to you at reconciliation. That’s exactly why the pre-tax price, not the pump sticker, is the number to optimize around.
Leveraging Technology: Fuelbook
Here’s the practical problem: those state IFTA rates change every quarter, and they don’t move in any pattern you can memorize or predict. You can’t just remember “Texas is cheap” and fuel there forever, because the rates shift underneath you. That’s exactly why I recommend Fuelbook. The app shows you both the pre-tax fuel price and the IFTA tax separately, in real time, at stations along your route. Instead of guessing from the pump sticker (which blends the two together and hides the number that actually matters), you can see the true pre-tax cost and buy where the fuel is genuinely cheapest that day. Used alongside your discount programs, it’s one of the simplest ways to stop leaving money at the pump.
Fuel Cards and Discount Programs
Fuel cards are one of the biggest levers on your fuel cost. Most fuel companies offer them to attract and keep customers, and they can knock real money off every gallon. The catch is that not all cards are created equal, and the discount gap between them is enormous.
To put that in perspective from my own experience: a typical branded fuel-chain card, like a Love’s card, might get you around $0.16 per gallon, with the higher end (closer to $0.26) usually reserved for high-volume accounts or introductory rates. That’s fine, but it’s a fraction of what a dedicated discount program delivers. Understanding that gap is what separates drivers who fuel smart from drivers who leave hundreds of dollars on the table every month.
A few things to know about fuel cards generally: they often come with short payment terms (frequently a week or less, which lets you run the load before the fuel bill is due), some charge monthly fees, and most are negotiable. If you can show you’re getting better prices elsewhere, many will match or beat it, so it’s worth carrying more than one and playing them against each other.
