Art and Collectibles Capital Gains Tax Treatment Parity Act - Amends the Internal Revenue Code to: (1) eliminate the 28-percent capital gains tax rate for collectibles, thus allowing gain from the sale of collectibles (including art works) to be taxed at the 15-percent tax rate applicable to other investment property; (2) allow the creator of a literary, musical, artistic, or scholarly property a fair market value tax deduction for the donation of such property to a tax-exempt organization, if properly appraised and donated no sooner than 18 months after its creation.
