4 questions about Trump's dyed-diesel order and trucker fuel costs

Signed Monday, Oct. 5, the order gives Treasury five days to determine whether federal law allows the relief. That includes deciding whether a qualifying event occurred and which taxpayers were affected.

If Treasury finds the legal conditions are met, specified diesel excise taxes incurred from Oct. 5 through Dec. 31 can be deferred. The order also directs Treasury to have the IRS announce that it will not impose specified penalties for selling or using dyed diesel on highways during that period.

Treasury must issue guidance explaining who qualifies, what conditions apply and when deferred taxes must be paid. The order separately tells Treasury to explore ways to eliminate the eventual payment obligation, including through legislation. Until that obligation is removed through further action, the deferred tax may still come due. Euronews reported on the order’s tax and penalty provisions.

Who could use dyed diesel on highways, and how much might they save?

The clearest potential beneficiaries are truckers and agricultural haulers who can obtain dyed diesel and qualify under the federal rules. Farmers already use the fuel for qualifying off-road work; the added opportunity for them is using it in relevant highway vehicles.

The White House estimated that deferring federal taxes could free up about $60 on a 250-gallon fill. It said the amount could exceed $100 per fill where states take corresponding action. Those are administration estimates, not guaranteed discounts: fuel access, eligibility and state policy all affect what an operator might save immediately.

The federal order does not suspend state taxes or require states to do so. It encourages states to take similar steps. TIME reported that Arkansas, Indiana, Missouri, Nebraska and North Dakota had already offered some state relief for specified highway uses of dyed diesel. Rules and potential savings therefore vary by state.

Zippy Duvall, president of the American Farm Bureau Federation, welcomed the order, telling Euronews, “Every cent per gallon matters when you're running a fleet of grain trucks or hauling cattle hundreds of miles.” The order does not ensure that every farm fleet or hauler will qualify or be able to find the fuel.

A deferral can reduce what an eligible operator has to pay upfront, but it does not necessarily reduce the total tax owed. If the deferred amount must eventually be paid, the immediate help is a change in timing rather than a lasting cut in fuel costs.

Will the order lower costs for truckers and grocery shoppers?

The direct benefit depends on whether a trucker or agricultural hauler can obtain the fuel and meet the federal conditions. Most ordinary fuel stations do not sell dyed diesel, TIME reported, which limits direct access for motorists filling personal vehicles.

Lower fuel outlays for a carrier or farm business could ease one of its costs, but the order does not promise a specific reduction in freight charges, grocery prices or other consumer costs. It also does not require businesses to pass any savings to customers. How much, if any, would reach shoppers is unknown.

Fuel supply is another constraint. Analysts cited by TIME questioned how much a tax change could accomplish without addressing supply limits. They also raised the possibility that greater demand could strain dyed-diesel inventories and raise costs for farmers during harvest. That is a concern about a possible effect, not a confirmed outcome. The order directs the Agriculture Department to help ensure distribution in areas with high demand.

What are the limits and trade-offs of the tax relief?

State taxes remain separate from the federal measure. A state that does not take matching action can leave its own tax charges in place, narrowing the potential relief compared with the White House’s estimate for places where state action adds to the federal deferral.

There is also a public-revenue trade-off. TIME notes that diesel taxes help fund road construction and maintenance. A deferral changes when federal taxes are paid; if a later action eliminates the payment obligation, the government would not collect those deferred amounts. State tax reductions would likewise mean less revenue from those charges. The order does not make the federal deferral a permanent cut, so those possibilities should not be confused with what it has already done.

The next test is whether Treasury finds the legal conditions for relief are met and issues guidance spelling out eligibility and repayment timing. State decisions and the availability of dyed diesel will determine how much near-term help reaches road users—and whether expanded demand puts pressure on supplies farmers already use.
