26 U.S.C. § 6324B — Special lien for additional estate tax attributable to farm, etc., valuation

The record establishes that 26 U.S.C. § 6324B was added by Public Law 94–455, title XX, § 2003(b), enacted October 4, 1976, 90 Stat. 1861. The source credit further shows that the section was subsequently amended three times: by Public Law 95–600, title VII, § 702(r)(4), in 1978; by Public Law 96–222, title I, § 108(d), in 1980; and by Public Law 97–34, title IV, § 421(d)(2)(B), in 1981. These citations indicate a period of active refinement in the years immediately following enactment, followed by no further amendment activity reflected in this credit. Public Law 94–455 is commonly known as the Tax Reform Act of 1976, a major piece of federal tax legislation. The Act is generally understood to have made extensive changes across the estate and gift tax system, including the introduction of special-use valuation rules for certain farm and closely held business real property under section 2032A. Section 6324B appears connected to that broader reform, as it creates a lien mechanism tied to the additional estate tax that may become due if such specially valued property is later disposed of or ceases to be used for its qualifying purpose. Beyond this general connection to the 1976 Act's estate tax provisions, the record does not establish the specific legislative reasoning behind the particular lien mechanics, security-substitution provision, or the details added by the later 1978, 1980, and 1981 amendments. Any more specific account of congressional intent for those changes would be speculative.
