This course will provide tax practitioners with an overview of recent depreciation changes. The panel will provide an overview of the newly released bonus depreciation final and proposed regulations, explain Revenue Procedure 2019-33 to Make or Revoke Bonus Depreciation Elections, Alternative Depreciation System (ADS) calculations to comply with the 163(j) exception for certain real estate, qualified improvement property (QIP) uncertainties, Section 179 opportunities, and the new vehicle safe harbor.


On September 13, 2019, the Treasury Department and the Internal Revenue Service issued final and proposed regulations regarding the first-year bonus depreciation under Section 168(k). The regulations clarify bonus eligible property, binding contract rules, component parts, ADS requirements with floor plan financing, self-constructed property, and more. These new rules could create additional opportunities for additional bonus depreciation for taxpayers.

For years 2016 and 2017, practitioners had little time to consider or had already filed tax returns, when the IRS issued proposed regulations in August 2018 regarding bonus elections under 168(k). To reduce the administrative burden on the IRS and practitioners of processing and filing amended returns, the IRS provided relief in Rev Proc 2019-33. This Rev Proc outlines streamlined procedures for electing in, out, or changing the percentage of bonus depreciation previously taken, which constitutes a change in accounting method.

Section 163(j)(7) allows certain real property and farming entities to elect out of the interest limitation. However, these businesses are required to depreciate certain property under ADS using a longer recovery period. Rev Proc 2019-08 explains how to make the transition to ADS. Not making the change appropriately could lead to the adoption of an impermissible accounting method.

QIP was intended to be eligible for 100% bonus depreciation and a 15-year depreciable life. The drafting error in the recent tax act and the wait for a correction has left practitioners in limbo as to how to handle QIP and resulted in some businesses having higher than anticipated tax bills.

Finally, the 2018 tax act increased first-year depreciation for passenger autos subject to the 280F limitations to $18,000 and provided a safe harbor calculation that allows businesses to deduct first-year depreciation above this threshold in the following year.

Listen as our panel of experts addresses the steps needed to change, revoke, or make bonus depreciation taken, how to calculate ADS depreciation to comply with IRC 163(j), best practices considering QIP uncertainties, and the new vehicle safe harbor.
