Section 179 Deduction. The Section 179 deduction is an election to recover all or part of the cost of certain qualifying property (new or used, as long as the previously used equipment is new to you). You can elect the Section 179 deduction instead of recovering the cost by taking annual depreciation deductions.
In 2024, the maximum Section 179 deduction for property placed into service was $1,220,000. However, businesses exceeding $3,050,000 of purchases in qualifying equipment are subject to the Section 179 deduction dollar-for-dollar phase-out. Accordingly, the election is eliminated if qualifying purchases exceed $4,050,000.
In 2025, the maximum Section 179 deduction is $1,250,000. The dollar-for-dollar phase-out begins at $3,125,000, and the deduction is eliminated if total purchases exceed $4,050,000.
Bonus Depreciation. Bonus depreciation allows you to elect to expense up to 100% of the cost of certain vehicles and equipment purchased and placed into service in the 2021 tax year. TCJA increased bonus depreciation from 50% to 100% and eliminated the rule that the asset be new. Therefore, bonus depreciation can be taken on new or used purchases (as long as it is new to you and not purchased from a related party, along with other limitations) with a useful life of 20 years or less. The ability to expense 100% of asset purchases goes through December 31, 2022. After that, the deduction decreases to 80% for the 2023 tax year, 60% for 2024, 40% for 2025, and 20% thereafter.
