For anyone in the trucking industry, maintaining accurate taxes associated with trucks is critical but not always simple. Because some of these taxes, including the federal excise tax, are so high, it is critical to get them right (failure to do so could result in financial losses through fines.)
What Is the Federal Excise Tax on Trucks?
The federal excise tax is imposed on some goods and products, including gasoline and cigarettes. Most of the time, these taxes occur at the time of purchase. The trucking industry has its own tax. It’s applied at the point of purchase of a truck and tractor. It applies to any vehicle that falls under their definition of a highway vehicle designed to transport loads on the same chassis as the engine, even if it is equipped to tow a vehicle. This includes semitrailers and trailers. It only applies to larger trucks, not the typical type that consumers might purchase.
The federal excise tax also applies to tractors, which the government defines as highway vehicles designed to tow a vehicle, including a trailer or semitrailer. The seller is liable for paying this tax at the time of the purchase. Understanding how this applies to you could be critical to ensuring your business remains tax-compliant.
Determining Taxable vs Exempt Vehicles
The Federal Excise Tax (FET) is imposed on the “first retail sale” of the truck after its manufacture or production, except for resale and long-term lease trucks. The tax, which is 12%, is levied on truck chassis exceeding 33,000 pounds. It also applies to trailers and semitrailers if they exceed 26,000 pounds and on tractors of 19,500 pounds or more and have a combined weight of more than 33,000 pounds.

The truck seller is responsible for collecting and reporting the taxes. You must submit quarterly documentation of these taxes through IRS Form 720.
Calculating Federal Excise Tax
To calculate the federal excise tax, apply the rate listed in the Internal Revenue Code Section 4051. At this time, it is 12%. That means the seller must collect 12% of the retail sale price on the taxable item at the time of purchase.
You must then submit Form 720 on the appropriate due date based on when the sale occurred. It must be submitted within the quarter:

- Sales in January, February, and March must have Form 720 submitted by April 30th of that year.
- Sales from April, May, and June must have the form submitted by July 31st.
- Sales that occur in July, August, and September are due to be paid by October 31st.
- Sales in October, November, or December must be paid by January 31st of the following year.
Common Challenges in FET Tax Compliance
Some factors can make the FET complicated or confusing. Here are a few things to keep in mind.
Used trucks
The federal excise tax does not apply to used trucks. It only applies to the first retail sale of the truck.
Imported trucks
If you export a truck as a dealer and then import it again to make a sale, even if it is a used truck, that will be taxed. It is considered the first sale of the truck.
Exemptions
Several sales could be exempt from this excise tax, including:

- Sales to Indian tribal governments, only the transaction involving the exercise of an essential tribal government function
- Sales to a state or local government for its exclusive use
- Sales for use by a purchaser for further manufacture of other taxable articles
- Sales to a qualified blood collector organization for the collection, storing, or transporting of blood
- Sales for export or resale by the purchases to second purchases for export
- Sales to the United Nations for official use
Heavy Vehicle Use Tax
The truck owner or buyer is responsible for filing and paying the Heavy Highway Vehicle Use tax through Form 2290. This is an annual tax to continue the use of heavy, load-bearing vehicles. This applies to trucks that weigh 55,000 pounds or more.
Best Practices for FET Tax Compliance
- Remain compliant by staying up to date on the laws and changes to them. The tax code could change in any year, and it is your responsibility to make payments accurately and on time.
- Keep accurate records of all taxes collected. It is the seller’s responsibility to collect and maintain these taxes for payment on the date listed above. If you do not have this information, it could be critical and costly.
- Determine if any tax credits apply. In previous years, tax credits have helped reduce costs.
- Instruct the purchaser of the truck, who is paying the tax credit, to reach out to their accountant to document and maintain these costs for their own tax purposes down the road.
- Note that other taxes may apply as well, including other federal excise taxes. This is often on fuel, heavy vehicles, and communications.
Key Takeaways for FET Tax
Any business that sells a truck, one that could be considered used as a highway vehicle, must require payment of the federal excise tax at the time of the purchase. The buyer pays that time at the time of the sale, and the seller collects and reports those funds to the IRS. As with any type of tax filing and documentation, it is critical to get it accurate. If you make any type of mistake, such as errors in the figures you use, that could lead to financial losses down the road – including fines for not collecting accurate taxes.

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.

For many manufacturers, transportation is viewed as a necessary cost center—an operational function that ensures raw materials arrive on time and finished goods reach customers efficiently. Private fleets are often built to support this mission: dedicated trucks, branded trailers, and drivers aligned with company service standards. The mindset is clear—we are a manufacturer, not a trucking company. But that distinction, while operationally convenient, may be financially limiting. In today’s freight environment—marked by volatility, tightening margins, and increased competition—manufacturers operating private fleets are sitting on an underutilized asset. The question is no longer whether transportation is a cost center, but whether it could be a strategic revenue generator . By choosing not to operate as a for-hire motor carrier, manufacturers may be missing significant opportunities across revenue, cost optimization, tax strategy, and market positioning. Let’s explore what those lost opportunities look like. 1. Revenue Left on the Road The most obvious missed opportunity is direct freight revenue . Private fleets are often underutilized in one or more ways: Empty backhauls Partial loads Idle equipment during off-peak periods Regional imbalances (e.g., strong outbound lanes but weak inbound demand) A for-hire carrier monetizes all of these inefficiencies. A private carrier absorbs them. If your trucks are returning empty 30–40% of the time, that is not just inefficiency—it’s forgone revenue. In a for-hire model, those empty miles could be converted into: Spot market loads Contract freight with complementary shippers Dedicated lanes for third-party customers Even modest utilization improvements can materially change the economics of a fleet. For example, capturing revenue on backhauls alone can offset a significant portion of total fleet operating costs. Bottom line: Private carriers pay for capacity. For-hire carriers sell it. 2. Cost Structure Distortion Private fleets often operate under a different financial lens than for-hire carriers. Costs are embedded within the broader manufacturing P&L, making it harder to: Benchmark transportation performance Identify inefficiencies Optimize pricing per mile or per load Because the fleet is not generating revenue, it is judged primarily on service—not profitability. This leads to several distortions: Over-servicing certain customers without understanding true cost-to-serve Running suboptimal routes to meet internal expectations Lack of pricing discipline compared to market carriers A for-hire structure forces discipline. Every mile has a rate. Every lane has a margin. Without that framework, manufacturers may be: Subsidizing inefficient routes Masking transportation losses within product margins Missing opportunities to rationalize their network 3. Tax Optimization Opportunities One of the most overlooked differences between private and for-hire fleets lies in tax treatment —particularly in areas like fuel tax recovery, apportionment strategies, and indirect tax optimization. For-hire carriers often benefit from: More aggressive fuel tax credit optimization (e.g., IFTA positioning strategies) Better alignment of miles driven with tax jurisdictions Strategic use of leasing structures and equipment ownership models Greater awareness of exemptions and recoverable taxes tied to transportation services Private carriers, by contrast, frequently: Leave fuel tax refunds unclaimed or under-optimized Fail to align operations with tax-efficient routing Miss opportunities to structure transportation activities in a more tax-advantaged way Additionally, operating as a for-hire carrier may open the door to: Different depreciation strategies Sales and use tax advantages in certain jurisdictions Structuring transportation as a separate profit center with distinct tax planning For companies already investing heavily in fleet infrastructure, these missed tax opportunities can compound quickly. 4. Underutilized Data and Pricing Intelligence For-hire carriers live and die by data: Lane pricing Market rates Seasonal demand fluctuations Network optimization Private fleets often have this data—but don’t use it the same way. Why? Because they are not actively participating in the freight market. This creates a blind spot: You may be operating lanes that are highly profitable in the open market—but you never monetize them You may be overpaying for outsourced freight without realizing your own fleet could service it more efficiently You lack real-time pricing benchmarks to evaluate internal decisions By not engaging as a for-hire carrier, manufacturers miss the opportunity to: Develop internal pricing expertise Leverage market rate intelligence Build a more dynamic, responsive transportation strategy 5. Missed Strategic Partnerships Operating as a for-hire carrier naturally leads to relationships : Brokers Shippers Logistics providers Freight platforms These relationships create optionality. Private carriers, however, are largely inward-facing. Their networks are designed around internal needs, not external demand. As a result, they miss opportunities to: Partner with complementary shippers (e.g., filling inbound lanes) Build dedicated capacity agreements Participate in collaborative shipping models Leverage brokerage or 3PL partnerships for overflow or optimization In a tight freight market, these relationships can be invaluable—not just for revenue, but for securing capacity, managing risk, and improving service levels. 6. Asset Utilization and ROI A truck is a capital asset. So is a trailer. So is a driver. The return on those assets depends on utilization. Private fleets often struggle with: Peak vs. off-peak imbalance Seasonal demand swings Regional inefficiencies Because the fleet is designed around internal demand, it cannot easily flex to external opportunities. For-hire carriers, on the other hand: Continuously adjust to market demand Reposition assets dynamically Maximize revenue per tractor and trailer If your fleet is idle even 10–15% of the time, the ROI on those assets is compromised. The question becomes: Why invest in capacity you’re not fully leveraging? 7. Talent and Operational Expertise Operating a for-hire carrier requires a different level of operational sophistication: Dispatch optimization Pricing strategy Customer acquisition Compliance management Private fleets often have strong operational teams—but they are not always trained or incentivized to think commercially. By not entering the for-hire space, manufacturers may be: Limiting the development of transportation leadership Missing opportunities to build internal logistics expertise Falling behind competitors who are evolving into hybrid models There is also a talent attraction angle. Transportation professionals are often drawn to environments where they can: Influence revenue Optimize networks Engage with the broader freight market A purely private fleet may not offer that same appeal. 8. Competitive Disadvantage Some manufacturers are already blurring the line. Hybrid models are emerging where companies: Maintain private fleets for core operations Operate as for-hire carriers on the margin Use brokerage arms to complement physical assets These companies gain: Better cost absorption Increased revenue streams Greater flexibility in managing freight If your competitors are monetizing their fleets while you are not, they may have: Lower effective transportation costs Higher margins More resilient supply chains Over time, that gap can widen. 9. Risk Diversification Transportation markets are cyclical. So are manufacturing sectors. By operating solely as a private carrier, your transportation function is tied entirely to your core business performance. A downturn in manufacturing demand means: Less freight Lower fleet utilization Higher per-unit transportation costs A for-hire model introduces diversification: Revenue from external customers Ability to shift focus based on market conditions Greater resilience during internal slowdowns This can act as a hedge against volatility in your primary business. 10. Barriers—and Why They Exist If the opportunity is so clear, why don’t more manufacturers make the shift? There are real barriers: Regulatory requirements (FMCSA authority, compliance) Insurance complexity Operational changes (dispatch, billing, customer management) Cultural resistance (“we’re not a trucking company”) Risk of service degradation to core customers These are valid concerns. But they are not insurmountable. Many companies address them through: Creating separate legal entities for for-hire operations Starting with limited lanes or backhaul programs Partnering with brokers or 3PLs Gradually building internal capabilities The transition does not have to be all-or-nothing. 11. A Practical Starting Point For manufacturers considering this shift, the first step is not to become a full-scale carrier overnight. It’s to analyze your current network : Where are your empty miles? Which lanes have consistent volume? Where do you have geographic imbalances? What is your true cost per mile? From there, identify low-risk opportunities: Backhaul monetization Dedicated lanes with trusted partners Pilot programs in select regions Even small steps can unlock meaningful value. Conclusion: Rethinking the Role of Transportation The statement “we are a manufacturer, not a trucking company” reflects a traditional view of transportation as a support function. But in today’s environment, that view may be outdated. Transportation is not just a cost to be managed—it is an asset to be optimized. By choosing not to operate as a for-hire motor carrier, manufacturers may be leaving value on the table in the form of: Untapped revenue Inefficient cost structures Missed tax advantages Underutilized assets Limited strategic flexibility The opportunity is not necessarily to become a trucking company—but to think like one . Because the companies that do will not just move freight more efficiently. They will turn transportation into a competitive advantage.
