First-Year Bonus Depreciation and Section 179 Expensing: Watch Out for the Downsides
Kathy Z. Jeziorski

Many companies are eligible for tax write-offs for certain equipment purchases and building improvements. These write-offs can do wonders for a business’s cash flow, but whether to claim them is not always an easy decision. In some cases, there are advantages to following the regular depreciation rules. So it is critical to look at the big picture and develop a strategy that aligns with your company’s overall tax-planning objectives.


Taxpayers can elect to claim 100% bonus depreciation or Section 179 expensing to deduct the full cost of eligible property up front, in the year it is placed in service. Alternatively, they may spread depreciation deductions over several years or decades, depending on how the tax code classifies the property.

Under the Tax Cuts and Jobs Act (TCJA), 100% bonus depreciation is available for property placed in service through 2022. Without further legislation, bonus depreciation will be phased down to 80% for property placed in service in 2023, 60% in 2024, 40% in 2025 and 20% in 2026. Then, after 2026, bonus depreciation will no longer be available. For certain property with longer production periods, these reductions are delayed by one year. For example, 80% bonus depreciation will apply to long-production-period property placed in service in 2024.

In March 2020, a technical correction made by the CARES Act expanded the availability of bonus depreciation. Under the correction, qualified improvement property (QIP), which includes many interior improvements to commercial buildings like leasehold improvements, is eligible for 100% bonus depreciation not only following the phaseout schedule through 2026, but also retroactively to 2018. So, taxpayers that placed QIP in service in 2018 and 2019 may have an opportunity to claim bonus depreciation by amending their returns for those years. If bonus depreciation is not claimed, QIP is generally depreciable on a straight-line basis over 15 years.

Section 179 also allows taxpayers to fully deduct the cost of eligible property, but the maximum deduction in a given year is $1 million (adjusted for inflation to $1.08 million for 2022) and the deduction is gradually phased out once a taxpayer’s qualifying expenditures exceed $2.5 million (adjusted for inflation to $2.7 million for 2022).

While 100% first-year bonus depreciation or Section 179 expensing can significantly lower your company’s taxable income, it is not always a smart move. Here are three examples of situations where it may be preferable to forgo bonus depreciation or Section 179 expensing:

  1. You Are Planning To Sell QIP
    If you have invested heavily in building improvements that are eligible for bonus depreciation as QIP and you plan to sell the building in the near future, you may be stepping into a tax trap by claiming the QIP write-off. That is because your gain on the sale — up to the amount of bonus depreciation or Section 179 deductions you have claimed — will be treated as “recaptured” depreciation that is taxable at ordinary income tax rates as high as 37%. On the other hand, if you deduct the cost of QIP under regular depreciation rules (generally, over 15 years), upon the building’s sale any long-term gain attributable to those deductions will be taxable at long-term capital gain rates (top rate of 25%), plus depending on your income level, the net investment income tax (3.8%) may apply.
  2. You Are Eligible for the Section 199A Pass-Through Deduction
    This deduction allows eligible business owners to deduct up to 20% of their qualified business income (QBI) from certain pass-through entities, such as partnerships, limited liability companies (LLC) and S corporations, as well as sole proprietorships. The deduction, which is available through 2025 under the TCJA, cannot exceed 20% of an owner’s taxable income, excluding net capital gains. (Several other restrictions apply).

    Claiming bonus depreciation or Section 179 deductions reduces your QBI, which may deprive you of an opportunity to maximize the 199A deduction. And since the 199A deduction is scheduled to expire in 2025, it makes sense to take advantage of it while it is available.

  3. Your Depreciation Deductions May Be More Valuable in the Future
    The value of a deduction is based on its ability to reduce your tax bill. If you think your tax rate will go up in the coming years, either because you believe Congress will increase rates or you expect to be in a higher bracket, depreciation write-offs may be worth more in future years than they are now.

Timing is everything

Keep in mind that forgoing bonus depreciation or Section 179 deductions only affects the timing of those deductions. You will still have an opportunity to write off the full cost of eligible assets, it will just be over a longer time period. Consideration should also be made for state conformity with federal bonus depreciation and Section 179 deduction. Your ORBA tax advisor can analyze how these write-offs interact with other tax benefits and help you determine the optimal strategy for your situation.
