... President Donald Trump signed an executive order on October 5, 2026, temporarily opening the door for red-dyed diesel fuel to be sold for and used in highway vehicles through the end of the year.
The move is aimed at reducing fuel costs for truckers, farmers, and other diesel users as restricted global diesel supplies and refining constraints continue to push prices higher. But despite some of the headlines circulating online, the order does not permanently make red diesel legal for highway use, nor does it automatically erase every federal and state tax associated with the fuel.
Instead, the executive order creates a temporary window of federal tax and penalty relief running from October 5 through December 31, 2026, while directing the Treasury Department and Internal Revenue Service to put the details into place. ...
How Much Could Diesel Owners Save?
The immediate federal savings potentially available are straightforward.
The federal highway diesel tax is 24.4 cents per gallon. That means eliminating or deferring that charge represents nearly $25 on every 100 gallons purchased.
For a commercial truck taking on 250 gallons, the White House estimates the federal portion alone represents roughly $60 per fill-up.
For owners of diesel pickups, the numbers are obviously smaller per tank but can still add up. A 30-gallon fill represents about $7.32 in federal diesel tax, while 50 gallons works out to approximately $12.20.
Those figures address only the federal side of the equation.
States impose their own fuel taxes and maintain their own dyed-diesel rules, and the executive order cannot simply eliminate those requirements nationwide. The administration is instead directing federal officials to work with states and encourage them to enact corresponding relief. ...
Is The Federal Tax Actually Gone?
This is where the distinction between the announcement and the underlying executive order becomes important. The order does not simply repeal the federal diesel excise tax through December 31.
Instead, Trump directed Treasury to determine whether existing law allows payment of certain taxes associated with highway use of dyed diesel to be deferred. If Treasury determines that authority exists, those payments are to be postponed without interest or penalties to the extent allowed by law.
Treasury is also directed to explore options for eliminating the eventual obligation to pay those deferred taxes, including possible legislative action.
So, while the White House is promoting the program as immediate tax relief, "deferred" and "eliminated" are not necessarily the same thing. ...
