Trump signs red-dyed diesel order at Nebraska rally, deferring 24-cent-per-gallon tax through year's end

President Donald Trump signed an executive order Monday night at a campaign rally in Grand Island, Nebraska, temporarily allowing the use of tax-free red-dyed diesel on public highways and deferring the federal excise tax on that fuel through December 31, with no interest, no penalties. The action, titled "Emergency Tax Relief on Diesel Fuel," drops the most direct federal lever available to a president on pump prices less than four weeks before Election Day.

Diesel prices skyrocketed from $3.76 a gallon before the Iran war to a record of $6.53 a gallon on September 22, according to AAA. The national average price for diesel on Tuesday was $6.32 a gallon. That is the backdrop against which the White House is acting, and it is squeezing an economy already central to the Republican Party's midterm pitch.

What the order actually does

The mechanics are specific. Taxes on diesel are based on how it is used. Road diesel for long-distance transport is subject to federal and state taxes, but diesel intended for farm vehicles and machinery is typically tax-free and dyed red, so regulators and inspectors can tell it apart from road diesel. Normally, driving a truck on a U.S. highway with dyed fuel in the tank is a federal penalty offense under Internal Revenue Code Section 6715.

Trump signed the executive order Monday evening to temporarily allow truckers and farmers to use red-dyed diesel, which is exempt from highway fuel taxes, and deferred related taxes on the fuel through the end of this year. It is therefore exempt from a 24.4-cent-per-gallon tax applied to diesel fuel sold for highway transportation.

Trump signed something real: on October 5, 2026, he signed an executive order that tells the IRS to stop penalizing on-road use of dyed diesel through December 31, 2026, and to defer the tax on it. The order does not abolish the federal diesel tax, does not make red diesel permanently legal in trucks, and does not override state law.

On the question of what happens to the deferred tax bill: the tax obligations do not go away completely, they are just deferred until next year. However, the order instructs officials to explore ways to forgive the tax obligations, including potentially legislation. Separately, the order directs the Secretary of the Treasury, in consultation with the Secretary of War, to defer payment of the federal excise tax imposed for on-road use of dyed diesel fuel for the remainder of the year without interest or penalties, and to explore pathways to eliminate the obligation to pay the deferred taxes.

The order relies on a law that lets the U.S. Treasury postpone tax deadlines for people affected by disasters or military action, and gives Treasury Secretary Scott Bessent five days, in consultation with Secretary of War Pete Hegseth, to determine whether those conditions are met and which taxpayers qualify. That is a legally contested basis for the action: using wartime emergency authority to reshape domestic fuel taxation through executive order, rather than an act of Congress.

The rally setting and the politics

Trump took his Republican midterm rescue mission to Nebraska, where he signed the executive order to ease limits on the tax-free use of red-dyed diesel, a decision he said would save "millions" for farmers and drive down the cost of all goods with just four weeks to go until the elections.

Trump said at the Grand Island rally: "The typical trucker will save more than $100 every time they fill up." He also told the crowd, in remarks reported by NBC News, that he was going to "sign a historic executive order to officially waive the off-road requirement and allow anyone to purchase tax-free red dye diesel for any reason," after he told the audience he did not "know what the hell" red dye diesel is.

Trump was campaigning for incumbent Sen. Pete Ricketts and Gov. Jim Pillen ahead of the November midterm elections. He was direct about the political overlay: Trump told the crowd, "This should absolutely assure your election. I guarantee it."

Nebraska Gov. Pillen had already moved on his own. Pillen signed an executive order September 24 temporarily lifting certain state penalties associated with the use of dyed diesel in highway-registered agricultural vehicles, and his order remains in effect for 90 days. Tennessee Gov. Bill Lee issued a parallel state-level suspension last week. Congress has never declared a gas tax holiday, but states are pulling the lever. States are taking on stubbornly high fuel prices squeezing Americans ahead of the midterm elections, pushing through tax holidays and other tactics to offer relief while federal efforts have stalled.

The savings math is conditional. The federal diesel tax is 24.4 cents per gallon, or about $60 on a 250-gallon fill. Where states match this federal action, savings will top $100 per fill. Agriculture Secretary Brooke Rollins projected broader gains: Rollins projected $640 million in savings for farmers. The USDA is actively working the logistics. The department is working with agricultural cooperatives, rural fuel distributors, farm suppliers and states to identify where harvest activity and fuel demand are highest and to monitor local supply and distribution problems.

The supply risk analysts flag

Not everyone sees this as clean relief. Tom Kloza, the senior energy and market adviser at Gulf Oil, told Newsweek: "I wouldn't call the executive order for diesel much ado about nothing, but it really doesn't alter the supply problems."

There is a specific tension between truckers and farmers. Some have warned that a rush of highway trucks buying dyed diesel could drain inventories and drive up costs for farmers during harvest, Time reported. The White House acknowledged the concern by directing the USDA to monitor distribution and protect farm access. The order instructs administration officials to encourage more states to adopt similar policies and to ensure farmers have access to dyed diesel in high-demand areas.

The underlying driver is global. Behind the price surge are several converging pressures: supply dislocations tied to the Iran conflict, Ukraine's drone campaign against Russian oil refineries, which led the Kremlin to curtail diesel exports, and a worldwide deficit in refining capacity. An executive order redirecting which diesel trucks may legally pump does not touch any of those causes.

The gas tax question hanging over Congress

The diesel order arrived the same day Trump told a reporter on the South Lawn that he is still thinking about a broader federal gas tax suspension. Trump said he is still "thinking about" whether the federal gas tax should be suspended, but a federal gas tax suspension would require the approval of Congress, which is out until the midterms. A suspension signed by the president would shave off 18.4 cents per gallon, and 24.4 cents off diesel.

That path is already blocked. A bill to suspend the federal government's 18.4-cent-a-gallon gasoline tax and 24.4-cent diesel tax through the end of 2026 has gone nowhere in the House, more than a week after Republican leadership let a floor vote slip away. Rep. Andy Harris of Maryland introduced the measure on September 15 with backing from Trump, framing it as relief for drivers and truckers facing high pump prices. Instead of a vote, the bill sits referred to the Ways and Means Committee, with House Speaker Mike Johnson acknowledging Republicans could not agree on how to proceed.

The House and Senate are out until after the election. House leadership thought about acting before they left, but there was internal dissent. With the gas tax route closed, the diesel executive order is the administration's available move, and it carries a real expiration date of December 31.

What to Watch

• The IRS clock. The order directs the Internal Revenue Service to announce guidance within five days, meaning that announcement is due by the end of this week. Watch whether the guidance broadens or narrows who qualifies.
• State matching. The $100-per-fill savings projection only holds if states suspend their own diesel taxes alongside the federal deferral. Governors in Tennessee and Nebraska are already aligned; how many others follow before the November 3 vote matters to the real-world price impact.
• Farm supply monitoring. USDA is watching for inventory drawdowns in harvest corridors. Any reported shortages for farm equipment, particularly in the Corn Belt, will test the order's core political promise.
• The deferred-tax endgame. Treasury is directed to find a path to forgive the deferred taxes entirely, potentially through legislation. That bill would have to move in a new Congress, making it a first-week-of-2027 fight for whoever controls the House.
• Gas tax signal. Trump said Monday, "We're thinking about that," when asked about a full gas tax suspension. If diesel prices do not drop quickly enough, expect that option to resurface in the post-election lame-duck session, where both chambers would still need to vote.
