In most cases, the gallons allowed for diesel credit are subject to Vermont sales and Use tax at 6% of the cost of the fuel (including tax). Registration is also required with the Vermont Department of Taxes, for further information call (802) 828-2551.

For all allowances, the vehicle MPG must be recalculated after excluding the allowance fuel. The resulting MPG must be reasonable considering the size, type, and usage of the vehicle(s).
