This series of blog posts is intended to highlight some key tax planning strategies resulting from the sweeping tax changes contained in the One Big Beautiful Bill Act (OBBBA). Many of those provisions, including the significant expansion of the Section 179 deduction, focus on incentivizing business investment. The expansion of the Section 179 provisions will presumably make this tax planning strategy more accessible for small and mid-sized businesses.
Background
The Section 179 depreciation deduction was first introduced in 1958. The Small Business Tax Revision Act initially allowed businesses to immediately expense up to 20% of qualifying equipment; 100% expensing was allowed starting in 1981. This provision is intended to allow businesses to deduct the full cost of qualifying equipment and property in the year the property is purchased, rather than having to spread the deduction over multiple years.
While other legislative changes have periodically increased the deduction limits and expanded the types of property eligible for the deduction, the expansion under the OBBBA marks the most significant increase to the deduction in recent years. Prior to these changes, the maximum Section 179 deduction for 2025 was $1,250,000, with a phaseout threshold of $3,130,000.
What Changed Under the OBBBA?
The OBBBA increased the Section 179 expensing limit to $2,500,000 and raised the phaseout threshold to $4,000,000 for property placed in service in tax years beginning after December 31, 2024. Both amounts will be indexed for inflation for taxable years beginning after 2025.
The Section 179 deduction has doubled the pre-OBBBA limit of $1,250,000, providing several important benefits for businesses. When companies make large investments in machinery, equipment, and other property improvements, the costs are generally recoverable through depreciation deductions and spread out over a number of years. When businesses elect the Section 179 deduction, immediate expensing of those costs is allowed in the year the property is placed into service. This incentive is designed to improve a company’s cash flow with a lower cost of capital, and encourages businesses to reinvest into their operations and employees.
Eligibility
The Section 179 deduction is available to most businesses, including corporations, partnerships and sole proprietors, but would not be applicable for estates and trusts. The following requirements apply for businesses to qualify and recognize the benefits from Section 179:
- The property must be tangible personal property (such as equipment, machinery, certain vehicles, and off-the-shelf software), or certain improvements made to qualified real property (including roofs, HVAC, fire protection, and security systems)
- The property must be acquired by purchase for use in the active conduct of a trade or business for at least 50% of the time
- The business income limitation must be considered to ensure the deduction will not generate a loss
- For each given year, the total Section 179 deduction cannot exceed the taxpayer’s taxable income from the conduct of all trades or businesses
- Any excess Section 179 elected would be suspended for that given tax year and can be carried forward indefinitely
While Section 179 is often compared to bonus depreciation (see related blog post), these two tax provisions differ in several important ways. A key difference lies in how businesses are permitted to apply the depreciation methods across their assets. In electing Section 179, businesses are allowed to choose which assets they want to expense, while bonus depreciation generally applies to all eligible property within a particular class, unless the taxpayer elects out. As taxpayers determine the most beneficial option for their situations, it’s also important to consider the impact these elections can have at the state tax levels since the rules vary by state.
Key Takeaways
Along with several other business investment incentives and infrastructure support, the expansion of the Section 179 expensing limit aims to provide businesses with a significant opportunity to review their capital expenditure plans and invest in their growth.
