Section 3020 - Credits and refunds(a) Credits. (1) A user who purchased fuel within this State from a dealer or distributor upon which he or she paid the tax at the time of purchase, or a user exempt from the payment of the tax under subsection 3003(d) of this title who purchased fuel within this State upon which he or she paid tax at the time of purchase, shall be entitled to a credit equal to the amount of tax per gallon in effect when the fuel was purchased. When the amount of the credit to which any user is entitled for any reporting period exceeds the amount of his or her tax for the same period, the excess shall be credited to the user's tax account and the user shall be notified of the date and amount of the credit by mail.(2) If the Commissioner determines that a tax, penalty, interest, or fee required by this chapter has been paid more than once by a user, or has been illegally or erroneously collected or computed, the excess amount paid or collected shall be credited to the user's tax account and the user shall be notified of the date and amount of the credit by mail.(3) A user who also sells or delivers fuel subject to the tax imposed by 32 V.S.A. chapter 233 upon which the tax imposed by this chapter has been paid shall be entitled to a credit equal to the amount of such tax paid pursuant to this chapter.
