**(b)** **Tax deducted upon refunds** Every person who refunds any amount with respect to a ticket or order which was purchased without payment of the tax imposed by section 4261 shall deduct from the amount refundable, to the extent available, any tax due under such section as a result of the use of a portion of the transportation purchased in connection with such ticket or order, and shall report to the Secretary the amount of any such tax remaining uncollected.
**(c)** **Payment of tax** Where any tax imposed by section 4261 is not paid at the time payment for transportation is made, then, under regulations prescribed by the Secretary, to the extent that such tax is not collected under any other provision of this subchapter, such tax shall be paid by the carrier providing the initial segment of such transportation which begins or ends in the United States.
**(d)** **Application of tax** The tax imposed by section 4261 shall apply to any amount paid within the United States for transportation of any person by air unless the taxpayer establishes, pursuant to regulations prescribed by the Secretary, at the time of payment for the transportation, that the transportation is not transportation in respect of which tax is imposed by section 4261.
