Red Diesel Tax Break Falls Flat With Drivers

Red dye diesel break is being greeted with a big yawn

An executive order signed by President Donald Trump on Oct. 5 is intended to provide temporary relief from high diesel prices, but trucking groups and fuel marketers say the measure offers limited practical help for over-the-road fleets.

The order, titled “Emergency Tax Relief on Diesel Fuel,” directs the Treasury Department to have the Internal Revenue Service suspend the usual federal penalty for selling or using red-dyed diesel in highway vehicles from Oct. 5 through Dec. 31, 2026. It also calls for the federal diesel tax on that fuel to be deferred during the same period, to the extent allowed by law.

That distinction is important. The federal tax is not canceled. The 24.4-cent-per-gallon excise tax is being pushed back, and trucking companies may still have to pay it later. The order says the deferred amount would not accrue interest or penalties during the authorized deferral period.

Red-dyed diesel is normally reserved for qualifying off-road uses, including agriculture and construction. The dye identifies the fuel’s tax treatment; it does not indicate a different power rating or fuel quality. Qualifying dyed diesel generally avoids the regular federal diesel excise tax, although it ordinarily remains subject to the 0.1-cent-per-gallon Leaking Underground Storage Tank tax.

Trump announced the move during an appearance in Nebraska before signing the order. In remarks quoted by American Truck Drivers, he described red-dyed diesel as essentially the same fuel used by highway trucks and said the order would allow it to be purchased and used for any purpose through the end of the year.

For trucking companies, however, the order has created as many questions as answers. Matt Muenster of Breakthrough Fuel noted in a client memo that Treasury was given five days to determine the legal authority for the deferral and identify eligible taxpayers. As of Oct. 6, the IRS had not issued implementing guidance, meaning the relief was not yet operational.

“For most interstate fleets, the practical risk and record-keeping burden outweighs the savings until Treasury and individual states publish clear guidance,” Muenster wrote.

The federal order also does not override state law. States must take separate action if they want to allow dyed diesel in highway vehicles or defer their own fuel taxes. Some states, including Montana and Minnesota, continue to prohibit the use of red diesel on public roads. Other states have issued limited waivers, but those actions have not generally eliminated state excise taxes.

That creates a significant problem for interstate drivers. A truck may legally purchase dyed fuel under a federal policy or in one state and then travel through another state that has not changed its rules. The fuel’s legal status in the state where it was purchased would not necessarily protect the carrier from liability elsewhere.

NATSO and the Society of Independent Gasoline Marketers of America said the order is primarily a farm-hauling measure because agricultural operations already maintain separate storage and distribution systems for dyed fuel. Farms and related businesses could potentially use fuel from their existing bulk tanks in trucks hauling commodities or equipment during harvest.

Expanding the practice to highway truck stops would be more difficult. Fuel marketers would need separate supplies, dedicated equipment and dyed product available at distribution terminals, or racks. Most highway truck-stop lanes do not currently dispense red-dyed diesel, according to Breakthrough Fuel.

“Selling dyed fuel at scale requires dedicated equipment and enough dyed supply at the rack,” NATSO and SIGMA said in an advisory to members. The groups added that neither fuel marketers nor commercial carriers are eager to reconfigure the supply chain for a temporary and uncertain benefit.

The potential savings are also relatively modest compared with the overall price of diesel. Fuel reports cited by trucking organizations put the national average above $6 per gallon, with prices above $8 in some regions. A savings of 24.4 cents per gallon would be meaningful for a high-mileage truck, but the benefit could be reduced or eliminated by compliance costs, state taxes, limited availability and the possibility that the deferred federal tax will eventually come due.

Owner-Operator Independent Drivers Association President Todd Spencer said the broader use of red-dyed diesel would provide “minimal relief” and emphasized that market stability is needed to bring down costs for independent truckers.

The American Trucking Associations said it appreciated the administration’s effort but also stressed that the practical details remain unresolved. Chief Advocacy and Public Affairs Officer Henry Hanscom pointed to the need for clear federal and state guidance on eligibility, reporting requirements and taxes that remain payable.

American Truckers United said the policy was causing substantial confusion and questioned whether it would deliver the relief intended for trucking businesses.

Even if the legal and distribution issues are resolved, industry groups say the order will not change the supply-and-demand conditions behind high diesel prices. Diesel inventories remain low, while global conflicts and disrupted trade flows continue to affect crude and refined-product markets. The order provides a temporary tax policy change, but it does not add diesel to the market or reduce the cost of producing and transporting it.

For now, the federal penalty relief applies through Dec. 31, 2026, but the deferral remains subject to Treasury and IRS guidance. No federal tax forgiveness has been granted, and state restrictions remain in place unless individual states act. Those uncertainties explain why trucking companies and fuel marketers have largely taken a wait-and-see approach rather than immediately shifting highway fleets to red-dyed diesel.
