Section 179 vs Bonus Depreciation: Which is Better?

By

Business owners often grapple with choosing between Section 179 and Bonus Depreciation for their accounting and tax strategies. Both offer substantial benefits, but which is the better option? This involves understanding the tax code, specific business needs, and staying updated with ever-changing regulations. Let's dive into these two powerful tax incentives to help you make an informed decision.

Before we delve into the details, it's crucial to underscore that the optimal choice between Section 179 and Bonus Depreciation largely depends on your individual business circumstances. Both offer immediate expensing of the cost of equipment or software, but they differ in thresholds, phaseout rules, and eligibility requirements.

Section 179 Deduction

Section 179 allows your business to deduct the full cost of qualifying equipment and/or software in the year of purchase, up to a set limit. After the Tax Cuts and Jobs Act (TCJA), the maximum deduction has been increased to $510,000 for 2021, with a total equipment and software purchase threshold of $2.59 million.

For example, say you're a small retail storeowner who spends $400,000 on new machinery in 2021. Under Section 179, you can deduct the full $400,000 from your taxable income in that year.

Eligible Property

Section 179 applies to both new and used equipment, as long as it's purchased and placed into service during the tax year. Moreover, it permits the deduction of off-the-shelf software, defined as software that's generally available to the public and not custom-built for your business.

However, Section 179 deductions begin to phase out dollar for dollar above a set threshold, which is $2.59 million for 2021. So, if your total equipment and software purchases exceed $2.59 million, you'll lose the Section 179 deduction entirely.

Rules and Limitations

While Section 179 offers generous deductions, it comes with several rules and limitations. It disallows the deduction of certain property types, such as intangible assets like patents, copyrights, and trademarks. Additionally, if your business operates at a loss, you generally can't take the Section 179 deduction that year, although there are exceptions for certain industries like farming and certain types of start-up businesses.

Also, keep in mind that taking the full Section 179 deduction may create an alternative minimum tax (AMT) liability. This is because the AMT doesn't allow for the same generous expensing as the regular tax. Always consult with a tax professional to ensure you're aware of potential mitigating strategies and to avoid unexpected tax liabilities.

Bonus Depreciation

Bonus Depreciation differs from Section 179 in its phaseout rules, eligibility requirements, and the type of assets it applies to. It allows for immediate expensing of a significant portion of the cost of qualifying property, with no limit on the total amount of equipment or software purchases. In 2021, the bonus depreciation rate stands at 100%, meaning you can deduct the full cost of qualifying assets in the first year.

For instance, let's say you're a manufacturer with $5 million in qualifying property purchases in 2021. Unlike Section 179, Bonus Depreciation won't phase out your deductions, allowing you to take a $5 million deduction in that year alone.

Qualifying Property

Bonus Depreciation applies to both new and used property, although the rules surrounding used property can be complex. It also generally applies to more types of assets than Section 179, including intangible assets like patents, copyrights, and trademarks, when they're purchased as part of an acquisition of another company's assets.

A critical distinction is that Bonus Depreciation is subject to an alternative minimum tax (AMT) adjustment, meaning that it could potentially increase your AMT liability in certain years. Again, it's vital to consult with a tax professional to navigate this potential pitfall.

Eligibility and Phaseout

Bonus Depreciation isn't available to all businesses. It's typically only available to businesses that have taxable income, and it phases out for businesses with substantial investment in fixed assets. However, the phaseout is gradual, beginning at $2.62 million in annual investment in qualified property and reaching full phaseout at $3.57 million.

Another critical aspect to consider is that while Bonus Depreciation offers significant upfront deductions, the full expensing may reduce your ability to take other deductions in future years. This is because you're 'using up' your depreciation deductions more quickly.

Changes Over Time

A final point to consider is that both Section 179 and Bonus Depreciation have seen significant changes in recent years, particularly with the passage of the Tax Cuts and Jobs Act (TCJA) in 2017. It's essential to stay informed about these changes, as they can significantly impact your tax strategy.

For example, the TCJA increased the maximum Section 179 deduction and the total equipment and software purchase threshold substantially. It also increased the bonus depreciation rate, and made several other significant changes. It's expected that these provisions will continue to undergo change as part of the ongoing fiscal policy debates.

Understanding these changes, and how they affect your business's specific circumstances, is crucial for maximizing your benefits. It's always wise to work closely with a tax professional who can provide tailored advice based on your business's unique needs and the ever-changing tax landscape.

Switching between these two deduction methods mid-year is not possible, so it's essential to plan your equipment and software purchases strategically. Consider the total cost, the type of assets, your business's profit profile, and your future tax needs when making purchasing decisions.

In the end, there's no one-size-fits-all answer to the question 'Is Section 179 better than Bonus Depreciation?' Each business will have unique circumstances, requiring a considered and informed decision. Regularly reviewing your tax strategy with a professional can help you take full advantage of the benefits these provisions offer and ensure your business remains tax-efficient while focusing on growth and success.
