What is the International Fuel Tax Agreement, what does it consist of, and why is compliance important? If you operate a qualifying motor carrier business in the U.S. outside Hawaii or in Canada, IFTA imposes regulatory obligations on your company and forms a critical component of your accounting and tax planning strategy. Efficient IFTA reporting can save you significant time and money, while poor IFTA report management can cost you financial penalties and even put you in legal jeopardy. In this comprehensive guide, we'll walk you through what you need to know to navigate the IFTA reporting process and stay in compliance while saving money.

What is IFTA? An Overview for Transportation Professionals

The International Fuel Tax Agreement is an accord governing qualifying motor carriers who pay fuel taxes in more than one state or provincial jurisdiction in the United States and Canada. It simplifies tax collection by applying fuel tax payments to an ongoing account and using quarterly reports to assess tax liabilities to each jurisdiction.


Operators pay taxes and receive refunds from the jurisdiction where their vehicles are based for registration purposes, where their operational control is centered and their records are stored or accessible, and where some travel is accrued. This is known as their base jurisdiction. Jurisdiction commissioners may elect to consolidate fleets based on multiple jurisdictions.


IFTA applies to the 48 contiguous United States and the 10 Canadian provinces bordering the U.S. Other parts of the U.S. and Canada participate voluntarily.


IFTA applies to qualified motor vehicles (QMV) used, designed, or maintained for the transportation of persons or property and meeting one of the following additional criteria:

  • Two axles with a gross vehicle or registered gross vehicle weight over 26,000 lbs. or 11,797 kgs; or
  • Three axles regardless of weight; or
  • Combined weight or gross weight exceeding 26,000 lbs. or 11,797 kgs.


IFTA carriers receive a license and decals to display compliance. Licensees file taxes once quarterly from their base jurisdiction, which handles payments, refunds, and audits.

Why Was IFTA Created?

The states of Arizona, Iowa, and Washington created IFTA in 1983 to simplify fuel tax reporting in the transportation industry. At that time, the industry was struggling with excessive paperwork stemming from obligations to comply with regulations in multiple jurisdictions and had asked Congress to intervene. Following 1984 federal legislation authorizing a review of state tax collection methods, IFTA gradually received nationwide adoption, completed in 1996.

Why Accurate IFTA Reporting Matters

Accurate IFTA reporting saves you time correcting paperwork, helps ensure you remain in compliance, avoids costly financial penalties, and can save you money if you're entitled to refunds.

Key Components of an IFTA Report

IFTA reports vary by jurisdiction, but they generally include:

  • Total IFTA miles
  • Total non-IFTA miles (traveled in areas outside IFTA jurisdiction)
  • Taxable miles
  • Taxable gallons (based on dividing taxable miles by miles per gallon)
  • Tax paid gallons
  • Net taxable gallons (taxable gallons minus tax-paid gallons)
  • Tax rate
  • Tax or refund due
  • Interest
  • Total tax or refund due after interest



IFTA forms collect this information for each jurisdiction traveled.

Mileage Tracking

IFTA requires you to track mileage for each jurisdiction traveled. Under federal law, most carriers must use an electronic logging device (ELD) to track mileage, with some exemptions, as in cases of temporary device malfunction.

Fuel Purchases and Receipts

To comply with IFTA, you must keep all receipts to maintain records on where and when you purchased fuel, what type of fuel you purchased, price per gallon, and total gallons bought.

Jurisdiction Breakdown

IFTA requires you to record information for all jurisdictions traveled. IFTA forms break down jurisdictions in rows so you can enter data for each row. IFTA reporting software can simplify this process.

Common Challenges in IFTA Reporting

The biggest IFTA reporting challenges include:



  • Estimating mileage and gallons
  • Remembering to log all miles, including unloading or personal miles
  • Remembering to record odometer or GPS problems
  • Meeting reporting deadlines
  • Failing to ensure up-to-date compliance for any software used to collect data


Failing to address these challenges can trigger an audit of your company.

Best Practices for Simplifying IFTA Compliance

You can simplify IFTA compliance by adhering to recommended best practices:


  • Use routing software to optimize your mileage and minimize your fuel taxes
  • Use electronic logging devices compatible with the Federal Motor Carrier Safety Administration (FMCSA)
  • Equip drivers with paper logs for backup in the event of ELD malfunction or other emergencies
  • Use IFTA reporting software to automate your reporting processes
  • Integrate your ELD and fuel card data with your reporting software
  • Maintain all fuel receipts for at least four years after your filing date or due date (whichever comes first) in the event of an audit (six-and-a-half years is better to simultaneously ensure compliance with the International Registration Plan)
  • Conduct periodic IFTA audits to verify the accuracy of your recordkeeping system
  • Use automated notification systems to ensure you meet filing deadlines
  • Create at least three backups of all records in at least two different media (such as your local device and the cloud), with at least one copy stored in a different physical location
  • Work with a transportation tax consultation specialist to review your compliance procedures



Following these best practices can save you significant labor while increasing the accuracy of your reporting and improving the efficiency of your reporting processes.

Leverage Technology for Accurate Tracking

Technology such as ELDs and IFTA reporting software can increase the accuracy of your tracking.

Organizing and Maintaining Records

IFTA requires you to keep records of driving mileage and fuel purchases. You must maintain records for at least four years, but six-and-a-half years will also ensure International Registration Plan compliance.

Consequences of IFTA Non-compliance

IFTA non-compliance can trigger financial penalties, audits, IFTA license revocation, impoundment of loads, having vehicles placed out of service, and ultimately, being put out of business.

A restructuring project lives or dies on a single question: does the new structure actually lower your tax — in every state you touch — without creating new exposure somewhere else? Answering that takes two things most firms don't pair together: deep transportation tax expertise and a disciplined project method. Transportation Tax Consulting brings both. We build the project around your footprint, not a template We start by mapping how your business is taxed today — federally and across all 51 jurisdictions where your equipment, mileage, and people create obligations. That diagnostic is where the real opportunities surface, and it's the step generalist firms skip when they reach for an off-the-shelf structure that wasn't designed for a motor carrier. We pull the levers that are specific to transportation The savings in a transportation restructure come from levers other advisors don't see: separating operating, asset-holding, and equipment-leasing entities; situating them where they reduce sales and use tax, property tax, and income and franchise tax; structuring intercompany leasing; and accounting for mileage-based apportionment, rolling stock exemptions, nexus, and the interplay of FET, IFTA, and IRP. We design the structure around how transportation is actually taxed, not how a typical business is. We model the savings before you spend a dollar restructuring Before you commit to anything, we quantify the projected effective-rate reduction and stress-test it against alternative structures. You see the numbers — state by state, scenario by scenario — including any new apportionment or nexus exposure a given option would create. The decision to proceed is driven by a model, not a hunch, and you know what the project is worth before you fund it. We quarterback execution alongside your counsel We lead the tax design and run the project end to end. The legal mechanics — forming entities and drafting agreements — sit with your attorneys, and we work in lockstep with them so the executed structure delivers the tax result it was engineered to produce. You get a single team driving the engagement, not a pile of disconnected advice. We make the result defensible and audit-ready Minimizing tax only matters if the position holds up. Every element of the structure is supported by primary-source analysis and contemporaneous documentation, built to withstand state examination and to answer, clearly, how and why the structure was put in place. We stay with you after close A structure is only as good as the compliance that follows it. We carry the project through to ongoing multistate filing and monitoring — and because we're already inside your tax data, we continue surfacing recovery opportunities and structural refinements long after the restructure is complete. The result: a measurably lower multistate tax burden, delivered by a structure that was diagnosed, modeled, executed, and defended by a team that does nothing but transportation tax.

In trucking, everyone talks about rates per mile. But surprisingly few transportation professionals truly understand the hidden forces shaping those numbers. Cost per mile (CPM) is more than a spreadsheet formula — it’s the heartbeat of profitability, fleet survival, driver retention, and long-term strategy. The most successful transportation companies are not always the ones hauling the most freight. Often, they are simply the ones that understand their cost structure better than everyone else. Here are some of the most overlooked — and surprisingly fascinating — facts about transportation cost per mile. 1. One Extra MPH Can Cost Thousands Per Truck Per Year Most drivers and managers underestimate how dramatically speed impacts fuel economy. A truck running 70 MPH instead of 65 MPH may only arrive minutes earlier, but fuel efficiency can drop by 0.5 to 1 MPG depending on terrain and equipment. For a truck running 120,000 miles annually: A 1 MPG loss can increase fuel cost by over $8,000 annually per truck Across a 100-truck fleet, that can exceed $800,000 yearly The shocking part? Many fleets focus harder on rate negotiation than speed management, even though speed discipline can create larger margin improvements. 2. Empty Miles Hurt More Than Most Fleets Realize Deadhead miles are often treated as “part of trucking,” but many strategic planners fail to measure their true impact. An empty mile still creates: Fuel expense Tire wear Maintenance Driver wages Depreciation Insurance exposure A truck with a $2.00 loaded CPM may actually require $2.45+ revenue CPM when deadhead is included. The industry’s biggest hidden leak is not fuel. It’s unproductive miles. 3. Tires Cost More Per Mile Than Many Office Departments A typical long-haul tractor-trailer can burn through: 18 tires Multiple replacements yearly Thousands in alignment and wear-related issues Tires alone often account for: 3–5 cents per mile That sounds small until you realize: 5 cents × 120,000 miles = $6,000 annually per truck Poor inflation management can reduce tire life by 20% or more. Many fleets obsess over diesel prices while ignoring one of their most controllable expenses sitting literally on the ground. 4. Driver Turnover Quietly Raises Cost Per Mile Everywhere Most people think turnover only affects recruiting costs. In reality, turnover raises: Accident frequency Idle time Fuel usage Maintenance issues Insurance claims Late deliveries Customer churn A new driver often operates less efficiently than an experienced one familiar with routes, customers, and company procedures. Some analysts estimate high-turnover fleets unknowingly add: 10–20 cents per mile in indirect operational costs That can erase profitability faster than a soft freight market. 5. The Cheapest Truck Is Not Always the Most Profitable Truck Many fleets buy equipment based on purchase price instead of lifecycle CPM. A cheaper truck may: Break down more frequently Lose fuel efficiency sooner Create higher downtime costs Have lower resale value An expensive truck with better fuel economy and uptime may actually produce a lower total CPM over five years. Strategic fleets calculate: Total operating cost Residual value Maintenance curves Downtime probability Not just monthly payments. 6. Idle Time Is One of the Industry’s Most Expensive Invisible Costs A truck parked at a dock still burns money. Even when wheels are not turning: Insurance continues Driver hours are consumed Equipment depreciates Financing accrues Opportunity cost increases Some studies estimate detention-related inefficiencies can cost fleets: Tens of thousands annually per truck The most profitable fleets are often not the fastest fleets — they are the fleets with the least wasted time. 7. Fuel Surcharges Rarely Cover Actual Fuel Costs Perfectly Many shippers assume fuel surcharges completely offset fuel volatility. They usually do not. Why? Because surcharge formulas often: Lag market changes Ignore idle fuel burn Exclude reefer fuel Fail to account for out-of-route miles Use outdated baseline assumptions When diesel spikes quickly, carriers often absorb major temporary losses before surcharge programs catch up. 8. Maintenance Costs Rise Exponentially — Not Gradually A common misconception is that maintenance increases steadily over time. In reality, maintenance costs often rise like a curve. After certain mileage thresholds: Repairs become more frequent Downtime accelerates Parts failures multiply That is why some fleets trade equipment aggressively while others run equipment longer based on maintenance analytics. The smartest fleets know exactly when each truck stops being profitable. 9. Cost Per Mile Changes by Freight Type More Than Most Think Two trucks may drive identical routes but produce completely different CPMs depending on freight. Examples: Refrigerated freight increases fuel burn Heavy haul accelerates tire wear Hazmat increases insurance exposure Multi-stop freight destroys productivity Urban deliveries increase braking and idle time Many transportation professionals benchmark CPM too broadly without segmenting operations correctly. 10. The Most Dangerous Number in Trucking Is “Average CPM” Average CPM hides operational truth. One lane may be highly profitable while another silently destroys margins. One driver may average: 7.8 MPG Another: 5.9 MPG One customer may create: 30-minute turns Another: 4-hour detention delays Averages conceal inefficiency. Elite transportation strategists analyze CPM: By lane By customer By driver By trailer type By terminal By season That level of visibility separates surviving fleets from elite fleets. Final Thought Transportation cost per mile is not just an accounting metric. It is a strategic intelligence system. The fleets that dominate the future of transportation will not simply move more freight — they will understand their cost structure with greater precision than their competitors. In trucking, pennies per mile decide: profitability, expansion, acquisitions, bankruptcies, and survival. And most of those pennies are hiding in places the industry still overlooks.
