It shall be lawful for the Secretary to receive for internal revenue taxes (or in payment for internal revenue stamps) any commercially acceptable means that the Secretary deems appropriate to the extent and under the conditions provided in regulations prescribed by the Secretary.
If a check, money order, or other method of payment, including payment by credit card, debit card, or charge card so received is not duly paid, or is paid and subsequently charged back to the Secretary, the person by whom such check, or money order, or other method of payment has been tendered shall remain liable for the payment of the tax or for the stamps, and for all legal penalties and additions, to the same extent as if such check, money order, or other method of payment had not been tendered.
Notwithstanding section 3718(f) of title 31, United States Code, the Secretary is authorized to enter into contracts to obtain services related to receiving payment by other means where cost beneficial to the Government. The Secretary may not pay any fee or provide any other consideration under any such contract for the use of credit, debit, or charge cards for the payment of taxes imposed by subtitle A. The preceding sentence shall not apply to the extent that the Secretary ensures that any such fee or other consideration is fully recouped by the Secretary in the form of fees paid to the Secretary by persons paying taxes imposed under subtitle A with credit, debit, or charge cards pursuant to such contract. Notwithstanding the preceding sentence, the Secretary shall seek to minimize the amount of any fee or other consideration that the Secretary pays under any such contract.
Except as otherwise authorized by this subsection, no person may use or disclose any information relating to credit or debit card transactions obtained pursuant to section 6103(k)(9) other than for purposes directly related to the processing of such transactions, or the billing or collection of amounts charged or debited pursuant thereto.
Use and disclosure of information under this paragraph shall be made only to the extent authorized by written procedures promulgated by the Secretary.
