The claim may cover only fuel in respect of which the decedent would have been entitled to claim payments. For example, if an individual dies on July 15, 1982, prior to claiming payment under § 48.6427-1 of $1,000 or more applicable to fuel purchased and used for nontaxable purposes during the calendar quarter ending June 30, 1982, the decedent's executor or other legal representative may file a claim for payment covering that calendar quarter, and take the credit provided by section 39(a)(3) against the decedent's income tax on the income tax return for the short taxable year in respect of fuel purchased by the decedent and so used during the period from July 1, 1982, to July 15, 1982, the date of death.
