We use taxed diesel in construction equipment. Does every fuel receipt support an off-highway fuel-tax credit?
A fuel receipt alone does not prove a qualifying nontaxable use.

A fuel receipt alone does not prove a qualifying nontaxable use. An off-highway business fuel claim needs evidence of the fuel type, tax paid and actual eligible use. Highway vehicle use, mixed tanks and duplicate claims require separate review under the Form 4136 rules.
A specific business-owner situation
A contractor buys clear diesel for both excavators and road trucks from one delivery tank. The full delivery cannot be assigned to off-highway use without a supported allocation.
Illustrative example, not a client result.
What to establish before filing
- Identify eligible fuel and use categories.
- Track gallons issued to each asset.
- Reconcile supplier tax information and prior claims.
Which fact changes the answer?
Fuel consumed by eligible off-highway equipment differs from fuel powering highway transportation. The purchaser's industry does not determine every gallon's use.
A mistake to avoid
Do not claim the income-tax deduction and a fuel-tax recovery inconsistently without the required adjustment.
Records that support the decision
- Fuel invoices.
- Equipment issue logs.
- Gallons and credit reconciliation.
The decision to document
Build a gallons-based calculation and document the permitted claim route and any related expense adjustment.
