In the case of voluntary destruction, unless such destruction is carried out as provided in subsection (b); and
In the case of an unexplained shortage of bottled distilled spirits.
In any case in which distilled spirits are lost or destroyed, whether by theft or otherwise, the Secretary may require the proprietor of the distilled spirits plant or other person liable for the tax to file a claim for relief from the tax and submit proof as to the cause of such loss. In every case where it appears that the loss was by theft, the burden shall be upon the proprietor of the distilled spirits plant or other person responsible for the distilled spirits tax to establish to the satisfaction of the Secretary that such loss did not occur as the result of connivance, collusion, fraud, or negligence on the part of the proprietor of the distilled spirits plant, owner, consignor, consignee, bailee, or carrier, or the employees or agents of any of them.
Except as provided in paragraph (5), no tax shall be abated, remitted, credited, or refunded under this subsection where the loss occurred after the tax was determined (as provided in section 5006(a)). The abatement, remission, credit, or refund of taxes provided for by paragraphs (1) and (3) in the case of loss of distilled spirits by theft shall only be allowed to the extent that the claimant is not indemnified against or recompensed in respect of the tax for such loss.
The proprietor of the distilled spirits plant or other persons liable for the tax imposed by this chapter or by section 7652 with respect to any distilled spirits in bond may voluntarily destroy such spirits, but only if such destruction is under such supervision and under such regulations as the Secretary may prescribe.
Whenever any distilled spirits on which tax has been determined or paid are returned to the bonded premises of a distilled spirits plant under section 5215(a), the Secretary shall abate or (without interest) credit or refund the tax imposed under section 5001(a)(1) (or the tax equal to such tax imposed under section 7652) on the spirits so returned.
No allowance under paragraph (1) may be made unless claim therefor is filed within 6 months of the date of the return of the spirits. Such claim may be filed only by the proprietor of the distilled spirits plant to which the spirits were returned, and shall be filed in such form as the Secretary may by regulations prescribe.
All provisions of law, including penalties, applicable in respect of the internal revenue tax on distilled spirits, shall, insofar as applicable and not inconsistent with subsection (c), be applicable to the credits or refunds provided for under such subsection to the same extent as if such credits or refunds constituted credits or refunds of such tax.
