US Executive Order 14435: dyed diesel allowed on the highway without federal penalty, 1 October to 31 December 2026

Accepted

Executive Order 14435 of 5 October 2026 (91 FR 64747, published 9 October) directs the Treasury to defer the taxes of 26 U.S.C. 4041(a)(1)(A) and 4041(b)(1)(B) incurred from 5 October to 31 December 2026 and the IRS to impose no penalty under 26 U.S.C. 6715(a)(1)-(2) when dyed diesel fuel is sold for use or used on the highway. IRS release IR-2026-122 of 14 October applies the penalty relief from 1 October to 31 December 2026, for federal tax purposes only; the IRS FAQ of 23 October states that it does not apply to federal taxes on clear diesel. The EIA on-highway diesel retail price, taxes included, stood at 6.199 USD/gal on 5 October, 6.179 on 12 October and 6.127 on 9 November 2026; US distillate stocks fell from 105,138 to 99,259 thousand barrels between 2 and 30 October.

Organisations

Universe drawn from: NATSO and SIGMA member advisories on the order, as quoted in the trade press (FreightWaves and CPA Practice Advisor quote the two retail-fuel associations, OOIDA, ATA, Breakthrough and the National Asphalt Pavement Association; the advisories themselves are member documents and were not opened (natso.com answered 429).); National Agricultural Law Center — Recent changes to dyed diesel regulations (State-by-state list of orders and tax-agency notices (Nebraska, Arkansas, Alabama, Texas, North Carolina and others); used for the state authorities. Texas Comptroller and North Carolina Department of Revenue retained; entries naming only an elected official were left out.); National Council of Farmer Cooperatives — members (About 90 regional cooperatives, farm credit banks and state councils read; most are marketing or credit cooperatives with no fuel business. Fuel-supplying cooperatives (CHS, GROWMARK, MFA Oil) and two Nebraska local cooperatives with bulk fuel were then checked on their own pages.); Energy Marketers of America — who we represent (Federation of 48 state and regional associations of motor and heating fuel marketers; the member-association page answered 403, so state associations were taken from press coverage (Connecticut Energy Marketers Association).); NEFI — recent news (heating-fuel distributors) (Two member notices on the IRS relief (October 2026) read in full. NEFI's member list is not public; Northeast distributors and terminal operators (Petro, Dead River, Sprague, Global Partners) were taken from their own sites.); IRS newsroom — IR-2026-122, IR-2026-125 and dyed diesel FAQ (Implementing guidance; with the White House fact sheet of 5 Oct 2026, source for the federal bodies named by the order.); Trade and general press read on 2026-11-12 (Transport Topics, Trucking Dive, Heavy Duty Trucking, DTN Progressive Farmer, Tank Transport, States Newsroom (Louisiana Illuminator), Connecticut Public, AP via PBS; each cited as the evidence URL of the organisation it supports. Pages of Feedstuffs, CCJ, Farm Progress, Tennessee Lookout and WOOD-TV answered 403 and were not used.); Transport Topics Top 100 For-Hire Carriers 2026 (Screened for a large interstate truckload carrier based in a state with agricultural-only relief; Werner Enterprises retained as the single example, the others would carry the same deduction.).

Hypotheses

OPEN · confidence low · horizon 2026-12-02. The lowest value of road diesel minus residential heating oil over the EIA Monday surveys of 9, 16, 23 and 30 November 2026 is at or below minus 0.05 USD per gallon in any one week. The branch is defined by the gap alone. Read beside it, not defining the branch: on the survey of that low, residential heating oil against 6.138 and wholesale heating oil against 5.100 USD per gallon, their values of 2 November. With both at or above, the low is read as heating oil gaining at retail. With the low at or below minus 0.05 and either price under its value, the branch still holds and the low is read as taxed diesel falling faster than a lagging residential price: a pass-through reading with no information on the order. Reading rule: the values as they stand in the two EIA workbooks on Wednesday 2 December 2026; if one of the four prints is absent on 4 December the reading is made on three and says so, with fewer than three it is void; a later revision is recorded beside the reading and does not change it. On the same weeks of 2012 to 2025, with no relief in force, the low was at or below minus 0.05 in 1 year of 14 (2022), between minus 0.05 and 0.10 in 10, and at or above 0.10 in 3 (2014, 2020, 2021). The reading does not attribute its result to the order: weather, retail pass-through, state tax suspensions and supply into the Northeast move the same gap, and dyed and clear diesel leave the same terminal tank. Indicators: Lowest value of road diesel (taxes included) minus residential heating oil (no tax), EIA Monday surveys of 9, 16, 23 and 30 November 2026, as of 2 December 2026; Read beside, not defining the branch: residential heating oil price on the survey of the low, against 6.138 USD per gallon; Read beside, not defining the branch: wholesale heating oil price on the survey of the low, against 5.100 USD per gallon; EIA on-highway diesel price, the taxed leg of the gap, same surveys.

OPEN · confidence high · horizon 2026-12-02. The lowest value of road diesel minus residential heating oil over the EIA Monday surveys of 9, 16, 23 and 30 November 2026 is above minus 0.05 and below 0.10 USD per gallon, the band that contains the lows of 2024 and 2025 (0.018) and any crossing of zero of ordinary size. Reading rule: the values as they stand in the two EIA workbooks on Wednesday 2 December 2026; if one of the four prints is absent on 4 December the reading is made on three and says so, with fewer than three it is void; a later revision is recorded beside the reading and does not change it. On the same weeks of 2012 to 2025, with no relief in force, the low was at or below minus 0.05 in 1 year of 14 (2022), between minus 0.05 and 0.10 in 10, and at or above 0.10 in 3 (2014, 2020, 2021). A reading in this band carries no information on the order in either direction.

Road diesel minus residential heating oil is at or above 0.10 USD per gallon on all four EIA Monday surveys of 9, 16, 23 and 30 November 2026: heating oil loses ground on road diesel while the relief is in force, the direction of the EIA outlook of 10 November 2026. Reading rule: the values as they stand in the two EIA workbooks on Wednesday 2 December 2026; if one of the four prints is absent on 4 December the reading is made on three and says so, with fewer than three it is void; a later revision is recorded beside the reading and does not change it.

At least one text at any of the three addresses (IRS, Federal Register, White House presidential actions) moves the end of the federal penalty relief on highway use of dyed diesel (or of the non-enforcement) beyond 31 December 2026, whatever the price.

An early end or a narrowing of the relief by a Treasury text or a court is outside the three branches. Read beside the decision and not defining it: the EIA on-highway price of Monday 21 December 2026 against 6.199 and against the EIA outlook mean for December, 5.792; and any text under section 7508A, which settles the tax of the period and not the penalty.

OPEN · confidence low · horizon 2027-10-06. The EIA on-highway diesel price, taxes included, on the Monday survey of 4 October 2027 is at or above 6.199 USD per gallon, its level on the day the order was signed, 1.34 above the EIA outlook mean for October 2027 (4.859, outlook of 10 November 2026). A return of the relief at that level would be a decision, not a consequence of the print.
