Performing Artist Tax Parity Act of 2023 This bill modifies the above-the-line tax deduction for the expenses of performing artists (including commissions paid to managers or agents) to provide for a phaseout of such deduction for taxpayers whose adjusted gross income exceeds $100,000 ($200,000 for joint return filers). The $100,000 phaseout threshold is adjusted for inflation annually for taxable years beginning after 2023.
