Excise Tax Refunds

Schedule 1 Fuel Tax Refunds: Getting Back the Tax in Every Off-Road Gallon

Every gallon of taxed fuel burned in a generator, an excavator, a reefer unit, or a farm tractor carries federal excise tax the law never meant to keep. Form 8849 Schedule 1 is how the business that bought the fuel claims it back.

Quick Answer

Schedule 1 (Form 8849) refunds federal excise tax on fuel the buyer used for a nontaxable purpose — off-highway business use, farming, export, trains, buses, heating. The claim must total at least $750 (one quarter or aggregated quarters) and be filed during the quarter after the last quarter claimed. Smaller amounts roll into an annual claim or Form 4136. Refunds run at the tax in the price — $.183/gallon gasoline, $.243/gallon undyed diesel.

Uses that qualify

Nontaxable useTypical claimantsWatch out for
Off-highway business useConstruction equipment, generators, refrigeration (reefer) units, forklifts, compressorsExcludes personal use and motorboats; highway vehicles never qualify
Farming purposesFuel used on a farm for farming — tractors, harvesters, irrigationThe farming definition is specific; custom work has its own rules
ExportFuel shipped out of the U.S. in a trade or businessRequires documentary proof of exportation
Trains and qualifying busesRailroads; intercity and local bus operatorsBus claims use reduced rates listed on the schedule
Heating oil and boats (type of use 8)Undyed diesel or kerosene burned for heat or in a boatApplies to diesel and kerosene lines, not gasoline

The $750 rule and the filing window

Schedule 1 runs on three requirements, straight from the schedule’s instructions: the claim must be at least $750 — met with one quarter or by aggregating quarters of your income tax year no other claim covered; it must be filed during the first quarter following the last quarter included (July–December fuel: file January 1 to March 31); and only one claim per quarter. At $.243 per gallon of diesel, $750 is roughly 3,100 gallons — a single site generator or a small equipment fleet clears it in a quarter or two. Fuel that never reaches the threshold is claimed annually or swept onto Form 4136 with the income tax return; the refund-vs-credit guide compares the routes.

The dyed-fuel boundary

Refunds exist because you paid tax at the pump on undyed fuel and then used it nontaxably. Dyed diesel and dyed kerosene were sold without the tax — the red dye is the marker — so there is nothing to claim on them (save the $.001 LUST tax on exported dyed fuel), and Schedule 1 requires certifying your claimed fuel showed no visible evidence of dye. The clean setup for a business with both worlds: buy dyed fuel for off-road tanks where suppliers offer it, and claim Schedule 1 refunds on the undyed gallons that end up in off-road use anyway.

Schedule 1 FAQs

Who can file Form 8849 Schedule 1?
The ultimate purchaser — the business that bought the fuel (tax included in the price) and used it for a nontaxable purpose. Vendors who sold fuel tax-free use Schedule 2 instead; the two never overlap on the same gallons, and only one claim may be filed per gallon.
What counts as a nontaxable use?
The big ones: off-highway business use (construction equipment, generators, refrigeration units, forklifts — but not personal use or motorboats), use on a farm for farming purposes, export, use in trains and certain intercity or local buses, heating oil, and listed aviation uses. The full type-of-use table is in the Form 8849 instructions.
What is the $750 rule?
A Schedule 1 claim must total at least $750. You can reach it with a single quarter of fuel use or by aggregating quarters of your income tax year for which no other claim was made. The claim must then be filed during the first quarter after the last quarter included — a claim covering July–December must be in between January 1 and March 31. Amounts that never reach $750 are not lost: claim them annually, or on Form 4136 with the income tax return.
Can I claim a refund on dyed diesel?
No — dyed diesel and dyed kerosene are sold without the tax in the first place (that is what the dye marks), so there is nothing to refund; the only dyed-fuel claim is the $.001-per-gallon LUST tax on exported dyed fuel. Claims are for UNDYED fuel bought tax-paid and used nontaxably. Using untaxed dyed fuel on the highway is a separate, steep penalty.
How much is the refund per gallon?
Generally the federal excise tax that was in the price — the headline rates on the schedule are $.183 per gallon for gasoline and $.243 for undyed diesel and kerosene, with distinct rates for aviation fuels, alternative fuels, and bus uses. Rates print right on Schedule 1, so the arithmetic is gallons × the listed rate.
What records do I need?
The seller’s name and address and the dates of purchase, plus records supporting the gallons and the nontaxable use — fuel logs, equipment hours, delivery tickets. Export claims need proof of exportation such as the export bill of lading. Keep everything; fuel claims are examined by the gallon.
