31 CFR 342.6 - Taxation.
(a)General. For the purpose of determining taxes and tax exemptions, the increment in value represented by the difference between the purchase price and the redemption value received for a savings note is considered interest. The interest is subject to all taxes imposed under the Internal Revenue Code of 1986, as amended. The notes are subject to estate, inheritance, gift, or other excise taxes, whether Federal or State, but are exempt from all other taxation now or hereafter imposed on the principal or interest thereof by any State, or any of the possessions of the United States, or by any local taxing authority.
(b)Federal income tax on notes. An owner of savings notes who is a cash-basis taxpayer may use either of two methods for reporting the increase in the redemption value of the notes for Federal income tax purposes, as follows:
(1) Defer reporting of the increase to the year of final maturity, actual redemption, or other disposition, whichever is earlier; or
(2) Elect to report the increase for the year in which it accrues, in which case the election applies to all savings notes then owned and those subsequently acquired, as well as to any other similar obligations purchased on a discount basis.
