The Tax Cuts and Jobs Act (TCJA) has effectively lowered the cost of acquiring capital assets by making substantial changes to the income tax rules for bonus depreciation and other “cost recovery.” There’s a lot to discuss, but please bear with me. There’s a good chance that one or more of these changes will change your tax bill.

Bonus depreciation. Before the TCJA, taxpayers were allowed to deduct 50% of the cost of most new tangible property (other than buildings and some building improvements) and most new computer software in the year placed in service (with adjustment of the regular depreciation deductions allowed in that year and later years). The “50% bonus depreciation” was to be phased down to 40% for property placed in service in calendar year 2018, 40% in 2019 and 0% in 2020 and afterward.

But for property placed in service and acquired after Sept. 27, 2017 (with no written binding contract for acquisition in effect on Sept. 27, 2017), the TCJA raised the 50% rate to 100%. (Appropriately, 100% bonus depreciation is also called “full expensing” or “100% expensing”.)

Additionally, the post-Sept. 27, 2017 property eligible for bonus depreciation can be new or used. Also, certain film, television and live theatrical productions are now eligible.

On the other hand the TCJA repealed the eligibility of “qualified improvement property” (certain improvements to buildings other than residential rental buildings). And the TCJA excluded from bonus depreciation public utility property and property owned by certain vehicle dealerships.

The 2018/2019/2020 phase down (above) doesn’t apply to post-Sept 27, 2017 property. Instead, 100% depreciation is decreased to 80% for property placed in service in calendar year 2023, 60% in 2024, 40% in 2025, 20% in 2026 and 0% in 2027 and afterward.

Code Sec. 179 expensing. Before the TCJA, most smaller taxpayers could immediately deduct the entire cost of section 179 property up to an annual limit of $500,000 adjusted for inflation. For property placed in service in tax years that begin in 2018, the inflation adjusted limit was scheduled to be $520,000. The annual limit was reduced by one dollar for every dollar that the cost of all section 179 property placed in service by the taxpayer during the tax year exceeded a $2 million threshold adjusted for inflation. For property placed in service in tax years that begin in 2018, the threshold was scheduled to be $2,070,000. But for tax years beginning after 2017, the TCJA substitutes as the annual dollar limit $1 million (inflation-adjusted for tax years beginning after 2018) and $2.5 million as the phase down threshold (similarly inflation adjusted).

Before the TCJA, section 179 property included most tangible personal property as well non-customized (“off-the-shelf”) computer software. Generally, the only buildings or other land improvements that qualified were restaurant buildings and certain improvements to leased space, retail space or restaurant space that were treated as section 179 property under an election. The TCJA, for tax years beginning after 2017, eliminated these categories and substituted as an elective category the much broader qualified improvement property category (that is no longer eligible for bonus depreciation, see above). Also, taxpayers can, for buildings other than rental real estate buildings, elect to treat as section 179 property previously ineligible building components that are roofs, heating, ventilation and air conditioning property, fire protection and alarm systems, or security systems.

And items (for example refrigerators) used in connection with residential buildings (though not the buildings themselves) are eligible to be section 179 property.

Other rules for real property depreciation. If placed in service after 2017, qualified improvement property, in addition to no longer qualifying for bonus depreciation and being newly eligible as section 179 property, has a 15 year depreciation period (rather than the usual 39 year period for non-residential buildings).

Vehicles. The TCJA triples the annual dollar caps on depreciation (and Code Sec. 179 expensing) of passenger automobiles and small vans and trucks. Also, because of the extension of bonus depreciation, the increase, allowed only to vehicles allowed bonus depreciation, of $8,000 in the otherwise-applicable first year cap is extended through 2026 (with no phase-down).

Farm property. For items placed in service after 2017, the TCJA shortens the depreciation period for most farming equipment and machinery from seven years to five and allows many types of farm property to be depreciated under the 200% (instead of 150%) declining balance method.

Alternative minimum tax. Property eligible for bonus depreciation continues to be exempt from the unfavorable depreciation adjustments that apply under the AMT. However, the corporate AMT has been repealed; accordingly the election that corporations could make to give up bonus and other accelerated depreciation for bonus-depreciation-eligible property in exchange for a refund of otherwise-deferred AMT credits was eliminated.
