Section 179 vs. Bonus Depreciation: Which Is Right for Your Business?

Depreciation occurs when a physical asset loses value over time due to normal use and wear and tear. To reflect this, the IRS requires that businesses write off or depreciate the cost of an asset over the years of its useful life.

Traditional depreciation requires that businesses write off the cost of an asset over its total useful life, matching the expense with the use of the asset. However, some vehicles allow the entire expense to be deducted in the year the asset was placed into service. Bonus depreciation and Section 179 are incentives designed by the IRS to encourage businesses to invest in themselves by purchasing new equipment and receiving an immediate tax benefit.

This is especially beneficial to start-ups that must purchase extensive equipment and can use these deductions for substantial tax relief. While the basic concept for both methods is similar, there are differences between the two methods. The good news is that you can take advantage of both (or one or neither) if you so desire.

Key similarities

• Both deductions allow for serious write-offs in the year an asset was placed in service.
• Both deductions can be applied to new and used tangible property that was not inherited, gifted, or acquired from a related party.

Key differences

• Section 179 depreciation is capped by the IRS ($1,080,000 as of 2022) and is reduced by the dollar amount of purchases that exceed the IRS threshold ($2,700,000 as of 2022). Bonus depreciation has no annual limit on the deduction.
• Section 179 offers greater flexibility. Under Section 179, businesses can deduct any dollar amount of their choosing within the thresholds and can allocate the deduction among assets according to preference. This offers businesses a chance to pick and choose which assets and how much of those assets to cover or save. Using bonus depreciation, a business must deduct the full bonus percentage (80% in 2023, with a reduction of 20% per year until 2027, when it will be phased out entirely) for all assets within the chosen asset class, which would leave no depreciation remaining for future years.
• Section 179 is limited to the amount of taxable income, whereas bonus depreciation can be used to create a net loss.

Should you take Section 179, bonus depreciation, or both?

While bonus depreciation offers sweeping savings, a Section 179 deduction can be used to fine-tune your company's bottom line. This calculation will be unique for every individual company and should be based on careful consideration of the implications for the current year as well as future years. Consulting a tax professional can save your business a lot of money with the right depreciation strategy. 

Considerations for taking accelerated depreciation

As a business, you need to consider the fact that by electing to take accelerated depreciation, you are, in essence, relieving your current tax burden by giving up future deprecation in exchange.

You need to therefore weigh when the benefit of depreciation will be most impactful for your company's bottom line. Section 179 offers greater flexibility but also caps the benefit. Bonus depreciation has no limitations but may force a company to “waste" depreciation that it could benefit from in future years.

Accelerating depreciation also lowers the book value of your assets, which can affect balance sheet ratios that may impact your ability to borrow money. Also, should you choose to sell that asset, you may have to pay tax on the gain.

Be aware that some states treat Section 179 and bonus depreciation differently than the IRS. Careful consultation with a tax adviser or an accountant can help your business make the most of your money with an optimal combination of depreciation write-offs.
