This bill seeks to permanently modify the calculation of the business interest deduction limitation under the Internal Revenue Code. Specifically, it amends Section 163(j)(8)(A)(v) to remove the expiration date for allowing businesses to add back depreciation, amortization, and depletion when determining their adjusted taxable income. By making this allowance permanent, the legislation aims to provide ongoing tax relief and support for businesses. This change effectively increases the income threshold against which business interest deductions are limited, potentially allowing companies to deduct a greater portion of their interest expenses. The amendment is designed to apply retroactively to taxable years beginning after December 31, 2021, ensuring continuity from when the previous allowance expired.
