The IRS has issued another set of final regulations on the additional first-year depreciation deduction, otherwise known as 100% bonus depreciation. The deduction generally applies to qualifying property acquired and placed into service after Sept. 27, 2017, and before Jan. 1, 2023. The final regs offer guidance on the requirements that must be met for property to qualify for the deduction, including used property. They also provide rules for consolidated groups and components acquired or self-constructed after Sept. 27, 2017, for larger self-constructed property on which production began before Sept. 28, 2017.
