The IRS says it will not impose federal dyed-diesel penalties for highway sales or use from October 1 through December 31, 2026. A later notice and FAQ say the agency will not challenge failures to report the covered section 4041(a) liability on Form 720 or keep records solely for that liability. Other tax duties and state fuel rules remain; a final federal payment deadline has not been announced in these notices.
Key facts
- Federal dyed-diesel penalty relief runs October 1 through December 31, 2026.
- The IRS will not challenge specified Form 720 reporting and recordkeeping failures solely for covered section 4041(a) dyed-diesel liability.
- Other Form 720 liabilities and independently required records remain in scope.
- Federal relief does not override state fuel taxes or penalties.
Timeline
The October 14 IRS announcement made federal penalty relief nationwide and retroactive to October 1. On October 21, the agency added temporary return-filing, reporting and recordkeeping relief for covered dyed-diesel uses. Its October 23 FAQ says a taxpayer need not report those covered sales later, including on a fourth-quarter Form 720, but must still file Form 720 for other liabilities when otherwise required.
The new clarification gives fuel sellers and highway users a more specific federal paperwork rule. It does not settle whether the underlying excise tax will ultimately be payable, and the IRS says state fuel taxes and penalties remain separate. A carrier crossing state lines needs to check each applicable state position.
As of January 2026, the Energy Information Administration listed 24.4 cents per gallon in federal diesel taxes and fees, including a 24.3-cent excise tax. The temporary IRS announcement does not establish a comparable pump-price reduction or freight-rate change.
Federal penalty relief is now in effect
The IRS said October 14 that it would not impose penalties when dyed diesel is sold for highway use or used on highways nationwide from October 1 through December 31, 2026. The agency also said it would suspend ordinary federal collection and enforcement procedures during that period, reassign its fuel compliance officers and stop federal on-road dyed-fuel inspections. Sellers and distributors do not have to investigate or document the ultimate use of fuel sold during the relief window.
What the Form 720 clarification covers
The IRS's October 21 notice says it will not challenge failures to file, report or keep records solely attributable to covered section 4041(a) tax on dyed diesel used during the October 1–December 31 relief period. Its October 23 FAQ says covered sales do not have to be reported later, even if the Form 720 due date falls after year-end, and records need not be reconstructed. A taxpayer who must file Form 720 for other taxes must still do so and report those other liabilities. Records independently needed for another tax or for an exemption, credit or refund are not covered by this relief.
Payment and state rules remain separate
The White House order asked Treasury to consider postponing specified diesel excise-tax payments. The IRS has clarified reporting, but its published notices do not set a final payment deadline or forgive the underlying tax. Its FAQ also says the federal relief does not address state-imposed fuel taxes or dyed-fuel requirements. A carrier should check the relevant state agency and supplier before changing fuel purchases, especially across state lines. The IRS is considering, but has not announced, a grace period for residual red dye in tanks after the relief window. EIA's January 2026 federal diesel tax-and-fee total is not a promised pump-price cut.
