Commercial Vehicle Taxes: Excise Tax, HVUT, and Penalties

Businesses that put heavy trucks on the road face several distinct commercial vehicle tax rules, and each one has its own trigger, filing form, and deadline. A 12 percent federal excise tax applies to the first retail sale of qualifying trucks and trailers. An annual Heavy Highway Vehicle Use Tax of up to $550 applies to any vehicle with a taxable gross weight of 55,000 pounds or more. Carriers that cross state lines also owe quarterly fuel taxes through IFTA and apportioned registration fees through IRP. Knowing which tax hits when, and how to file it, is what keeps a fleet legal at the DMV window and out of penalty territory with the IRS.

The 12 Percent Federal Excise Tax at Purchase

Before a heavy truck ever moves under its own tags, the buyer may owe a federal excise tax (FET) of 12 percent on the purchase price. The tax applies to the first retail sale of truck chassis and bodies, trailer and semitrailer chassis and bodies, and highway tractors designed to pull a trailer.¹ It also covers parts and accessories sold with the vehicle or installed within six months of sale, unless the added cost stays at or below $1,000.

Lighter equipment is carved out. The FET does not apply to trucks with a gross vehicle weight of 33,000 pounds or less, trailers at 26,000 pounds or less, or tractors at 19,500 pounds or less (or with a combined tractor-trailer weight of 33,000 pounds or less).¹ Sales to state and local governments and nonprofit educational organizations are exempt, though that exemption is set to expire on October 1, 2028. Vehicles sold for export are exempt as well.²

The 12 percent rate applies to the full retail sale price. Legally the tax falls on the first retail sale, no matter how the parties divide it in the paperwork. Replacement parts installed after the vehicle enters service are not subject to the FET.

The Annual Heavy Highway Vehicle Use Tax

Once a heavy vehicle is on the road, the annual Heavy Highway Vehicle Use Tax (HVUT) applies to any highway motor vehicle with a taxable gross weight of at least 55,000 pounds.³ Taxable gross weight is the unloaded weight of the vehicle fully equipped, plus the semitrailers or trailers it typically hauls and the maximum load it customarily carries.⁴

The rate has two brackets:

55,000 to 75,000 pounds: $100 per year plus $22 for each 1,000 pounds (or fraction) above 55,000.
Over 75,000 pounds: a flat $550 per year.

A truck at exactly 55,000 pounds owes $100. A truck at 65,000 pounds owes $320. Anything over 75,000 pounds owes the same $550. The person who registers the vehicle pays the tax, which in most fleets is the business entity that holds the title. The HVUT is authorized through September 30, 2029, under the current statute.³

Filing Form 2290 and Paying the HVUT

The HVUT is reported on IRS Form 2290, and the tax year runs from July 1 through June 30.⁵ For vehicles already in service at the start of the tax year, Form 2290 is due by August 31. If a vehicle first hits the road in any other month, the deadline is the last day of the following month. A truck first used in October has a November 30 filing deadline.⁶

You don’t owe the full annual tax on a vehicle that enters service partway through the year. The HVUT is prorated from the first day of the month of first use through June 30.³ The Form 2290 instructions include partial-period tax tables that give you the exact dollar amount by weight category and month of first use.⁷

To file, you need your Employer Identification Number (EIN) and the 17-digit VIN for each taxable vehicle, and you enter each vehicle’s taxable gross weight in the correct column. Fleets with 25 or more vehicles must file electronically.³ Smaller fleets benefit from e-filing too, because the IRS returns the stamped Schedule 1 faster, and that document is what most state motor vehicle agencies require to issue or renew a registration on a taxable vehicle.⁷ Payments run through the Electronic Federal Tax Payment System (EFTPS). Keep both the payment confirmation and the stamped Schedule 1.

When the HVUT Doesn’t Apply

Some vehicles cross the 55,000-pound line without owing the tax:

Highway motor vehicles used by a state, county, city, or other political subdivision.⁸
Federal vehicles where the Secretary of the Treasury authorizes an exemption because taxing them would be a substantial burden with no net benefit to the government.⁸
Transit-type buses (not intercity) operated by carriers meeting a 60 percent passenger fare revenue test.⁸
Low-mileage vehicles. If you reasonably expect a vehicle to travel fewer than 5,000 miles on public highways during the tax period, collection is suspended. Cross the 5,000-mile line and the full tax becomes due.⁸

Agricultural and logging vehicles are handled separately on Form 2290 and may use a higher mileage threshold of 7,500 miles before the tax applies. Even when a vehicle is exempt or suspended, you still file Form 2290 to obtain the stamped Schedule 1 for registration.⁷

Credits for Sold, Destroyed, or Stolen Vehicles

If a truck is sold, destroyed, or stolen before the last month of the tax period, the HVUT already paid for the remaining months is not lost. The statute allows a prorated credit based on the months the vehicle was actually in service.³

Claim the credit on your next Form 2290 by subtracting the partial-period tax (based on months of actual use) from the full-year tax you originally paid. If you have no upcoming Form 2290 to offset it against, request a refund using Form 8849 (Claim for Refund of Excise Taxes) with Schedule 6 attached. You will need the VIN, the weight category, and the date of sale, destruction, or theft.⁷

Only one HVUT payment is owed per vehicle per tax period. A buyer is not required to pay a second round for the same period, though the buyer must file Form 2290 if the vehicle is first used on public highways under the buyer’s name during a new tax period.³

Interstate Carriers: IFTA and IRP

Carriers that operate across state lines face two additional compliance layers. The International Fuel Tax Agreement (IFTA) lets a carrier file a single quarterly return with its base jurisdiction, which distributes the appropriate share of fuel tax to every other state the carrier traveled through.⁹ Without IFTA, a truck running 15 states would need 15 separate returns.

IFTA returns are due quarterly by the last day of the month following the close of each quarter (April 30 for January through March, and so on). Filing requires mileage logs and fuel purchase records organized by jurisdiction. Late filing draws penalties even on a zero-balance quarter.

The International Registration Plan (IRP) applies the same principle to registration fees. Rather than fully registering a vehicle in every state it enters, IRP apportions registration fees to each jurisdiction based on the percentage of total miles driven there. A truck logging 40 percent of its miles in one state pays 40 percent of that state’s registration fee.¹⁰ Both IFTA and IRP are administered by each state’s transportation or revenue department, so filing portals and procedural details vary by base jurisdiction.

Penalties for Late Filing or Nonpayment

Missing the Form 2290 deadline triggers two IRS penalties that run at the same time. The failure-to-file penalty is 5 percent of the unpaid tax for each month (or part of a month) the return is late, up to 25 percent. The failure-to-pay penalty is 0.5 percent per month on any tax unpaid by the due date, also capped at 25 percent.¹¹ When both apply in the same month, the failure-to-file rate drops to 4.5 percent so the combined monthly charge is 5 percent of the balance. Interest accrues on top of both. The IRS may waive penalties for reasonable cause, but not for simple oversight.

Deliberate evasion is a separate matter. Willfully attempting to evade any federal tax is a felony carrying fines of up to $100,000 for individuals or $500,000 for corporations, plus up to five years in prison.¹²

Recordkeeping Requirements

Keep Form 2290 records for at least three years after the date the tax was due or paid, whichever is later, and make them available for IRS inspection. For a fleet, that means weight certifications, VINs, and stamped Schedule 1 copies for every vehicle across overlapping tax periods.

IFTA and IRP have their own retention rules. IFTA licensees must preserve mileage logs, fuel receipts, and trip reports supporting each quarterly return for four years from the later of the return’s due date or filing date, and must hold operational records and decals for four years after closing an IFTA account. IRP records, including the documentation behind the apportioned registration application, must be kept for three years following the close of the registration year. Auditors who find incomplete records assess tax on estimated mileage, which almost always exceeds what the actual numbers would produce.

Deducting Commercial Vehicle Taxes

Most commercial vehicle taxes are deductible as ordinary business expenses on the federal income tax return. The HVUT paid on Form 2290, IFTA fuel taxes, IRP registration fees, and the 12 percent FET built into a truck purchase price all qualify as deductible costs of doing business. The deduction lands in the tax year in which the expense was paid or accrued, depending on your accounting method. That does not erase the cash-flow hit of a large HVUT bill or a six-figure FET on a new truck, but it does reduce the effective cost.
