This legislative proposal amends Section 197(e) of the Internal Revenue Code of 1986, targeting the tax treatment of certain professional sports franchises. It introduces a new provision that prohibits the amortization of any "specified sports franchise" and related acquired items. A "specified sports franchise" is defined as one engaged in a professional sport designated for females that allows any individual whose sex is male to participate. For this purpose, "sex" is explicitly defined as an individual's reproductive biology and genetics at birth. The Secretary of the Treasury is tasked with prescribing regulations to verify such franchises and determine participation eligibility, with the amendment applying to property acquired after the date of enactment.
