Five Key Points About Bonus Depreciation


Like most business owners, you’ve probably heard about 100% bonus depreciation. It’s available for a wide range of qualifying asset purchases. But there are many important details to keep straight. Here are five key points about this powerful tax-saving tool:

1. It’s Scheduled to Phase Out.  Under current law, 100% bonus depreciation will be phased out in steps for property placed in service in calendar years 2023 through 2027. Thus, an 80% rate will apply to property placed in service in 2023, 60% in 2024, 40% in 2025, and 20% in 2026, and a 0% rate will apply in 2027 and later years.

For some aircraft (generally, company planes) and for the pre-January 1, 2027, costs of certain property with a long production period, the phaseout is scheduled to take place a year later, from 2024 to 2028. Of course, Congress could pass legislation to extend or revise the above rules.

2. Bonus Depreciation Is Available for New and Most Used Property.  In the past, used property didn’t qualify. It currently qualifies unless the taxpayer previously used the property or unless the property was acquired in specific forbidden transactions. (These are, generally, acquisitions that are tax-free or from a related person or entity.)

3. Taxpayers Should Sometimes Elect To Turn It Down.  Taxpayers can elect to reject bonus depreciation for one or more classes of property. The election out may be useful for certain businesses. These include sole proprietorships and business entities taxed under the rules for partnerships and S corporations that want to prevent “wasting” depreciation deductions by applying them against lower-bracket income in the year property was placed in service — instead of against anticipated higher bracket income in later years. Note that business entities taxed as “regular” corporations (in other words, those that aren’t S corporations) are taxed at a flat rate.

4. Bonus Depreciation Is Available for Certain Building Improvements.  Before the 2017 Tax Cuts and Jobs Act (TCJA), bonus depreciation was available for two types of real property: 1) land improvements other than buildings, such as fencing and parking lots, and 2) qualified improvement property, a broad category of internal improvements made to non-residential buildings after the buildings are placed in service.

The TCJA inadvertently eliminated bonus depreciation for qualified improvement property. However, the CARES Act of 2020 made a retroactive technical correction to the TCJA. The correction makes qualified improvement property placed in service after December 31, 2017, eligible for bonus depreciation.

5. 100% Bonus Depreciation Has Reduced the Importance of Section 179 Expensing.  If you own a smaller business, you’ve likely benefited from Sec. 179 expensing. This is an elective benefit that — subject to dollar limits — allows an immediate deduction of the cost of equipment, machinery, off-the-shelf computer software and some building improvements. Sec. 179 has been enhanced by the TCJA, but the availability of 100% bonus depreciation is economically equivalent and has greatly reduced the cases in which Sec. 179 expensing is useful.
