    (b) Coordination With Gift Tax.--Section 2512 of the Internal 
Revenue Code of 1986 (relating to valuation of gifts) is amended by 
adding at the end the following new subsection:
    ``(c) For the purposes of this chapter, the value of qualified 
historic property (as defined in section 2032B(b)(1)) transferred for 
less than an adequate and full consideration shall be valued under 
section 2032B.''.
    (c) Technical Amendments.--
            (1) Subparagraph (A) of section 2056A(b)(10) of the 
        Internal Revenue Code of 1986 is amended by inserting 
        ``2032B,'' after ``2032A,''.
            (2) The table of sections for part III of subchapter A of 
        chapter 11 of such Code is amended by inserting after the item 
        relating to section 2032A the following new item:

    (d) Effective Date.--The amendments made by this section shall 
apply with respect to the estates of decedents dying after the date of 
the enactment of this Act. Notwithstanding the preceding sentence, for 
the purposes of section 901 of the Economic Growth and Tax

be treated as being enacted before the date of the enactment of such 
Act.
Output: Amends the Internal Revenue Code to allow decedent estates to base the value of qualified historic property on the net earnings of such property for estate and gift tax purposes. Defines "qualified historic property" as any building designated as a national historic landmark for at least 25 years prior to the death of a decedent and originally used for residential or farming purposes.
