(2) the value of such property (or an interest therein) would have been included in the decedent’s gross estate under section 2036, 2037, 2038, or 2042 if such transferred interest or relinquished power had been retained by the decedent on the date of his death,
the value of the gross estate shall include the value of any property (or interest therein) which would have been so included.
(b) Inclusion of gift tax on gifts made during 3 years before decedent’s death
The amount of the gross estate (determined without regard to this subsection) shall be increased by the amount of any tax paid under chapter 12 by the decedent or his estate on any gift made by the decedent or his spouse during the 3-year period ending on the date of the decedent’s death.
