(a) Treasury certificates of indebtedness, Treasury notes, or Treasury bills of any series (not including interim receipts issued by Federal reserve banks in lieu of definitive certificates, notes, or bills) may be tendered at or before maturity in payment of internal revenue taxes due on the date (or in payment for stamps purchased on the date), on which the certificates, notes, or bills mature, or in payment of internal revenue taxes due on a specified prior date, but only if such certificates, notes, or bills, according to the express terms of their issue, are made acceptable in payment of such taxes or for the purchase of stamps. If the taxes for which the certificates, notes, or bills are tendered in payment become due, or the stamps are purchased, on the same date as that on which such certificates, notes, or bills mature, they will be accepted at par plus accrued interest, if any, payable with the principal (not represented by coupons attached) in payment of such taxes or stamps. If the taxes for which the certificates, notes, or bills are tendered in payment become due, or the stamps are purchased, on a date prior to that on which the certificates, notes, or bills mature, they will be accepted at the value specified in the terms under which such certificates, notes, or bills were issued. All interest coupons attached to Treasury certificates of indebtedness or Treasury notes shall be detached by the taxpayer before such certificates or notes are tendered in payment of taxes or stamps.

(b) Receipts given by a district director for Treasury certificates of indebtedness, Treasury notes, or Treasury bills received in payment of internal revenue taxes or for stamps as provided in this section shall contain an adequate description of such certificates, notes, or bills, and a statement of the value, including accrued interest, if any, payable with the principal (not represented by coupons attached), at which accepted, and shall show that the certificates, notes, or bills are tendered by the taxpayer and received by the district director, subject to no conditions, qualification, or reservation whatsoever, in payment of an amount of taxes or for stamps no greater than such value. Any certificate, note, or bill offered in payment of internal revenue taxes or for stamps subject to any condition, qualification, or reservation, or for any greater amount than the value at which acceptable in payment of taxes or stamps, as specified in the terms under which such certificate, note, or bill was issued, shall not be deemed to be duly tendered and shall be returned to the taxpayer.

(c) For the purpose of saving taxpayers the expense of transmitting Treasury certificates of indebtedness, Treasury notes, or Treasury bills to the office of the district director in whose district the taxes are payable, or stamps are to be purchased, taxpayers desiring to pay taxes, or purchase stamps, with such certificates, notes, or bills acceptable in payment of taxes or for the purchase of stamps may deposit such certificates, notes, or bills with a Federal reserve bank or branch, or with the Office of the Treasurer of the United States, Treasury Building, Washington, D.C. In such cases, the Federal reserve bank or branch, or the Office of the Treasurer of the United States, shall issue a receipt in the name of the district director, describing the certificates, notes, or bills by par or dollar face amount and stating on the face of the receipt that the certificates, notes, or bills represented thereby are held by the bank or branch, or the Office of the Treasurer of the United States, for redemption at the value specified in the terms under which the certificates, notes, or bills were issued, and for application of the proceeds in payment of taxes due or for the purchase of stamps on a specified date by the taxpayer named therein.

(d) In the case of payments of tax required to be deposited with Government depositaries by regulations under section 6302 of the Code, certificates, notes, or bills referred to in paragraph (a) of this section may be deposited with a Federal Reserve bank or branch, or with the Office of the Treasurer of the United States, in part or full satisfaction of such tax liability. As in the case of all remittances of amounts so required to be deposited, each such deposit of certificates, notes, or bills shall be accompanied by the appropriate deposit form in accordance with the regulations under section 6302. In such cases, notwithstanding paragraphs (b) and (c) of this section, receipts for such certificates, notes or bills shall no longer be issued in the name of the district director.
