Bonus depreciation is an additional first-year depreciation allowance under IRS code §168(k). It lets businesses deduct a percentage of the cost of qualifying equipment in the year placed in service, on top of (or instead of) Section 179.
2026 phase-down
Under current law, bonus depreciation is phasing down: 100% in 2022, 80% in 2023, 60% in 2024, 40% in 2025, 20% in 2026, and 0% in 2027 and after. (Some legislation may modify this; check with your CPA for the current year rate.)
Bonus vs Section 179
Section 179 has an annual dollar cap and a phase-out at high spending levels; bonus depreciation has no cap, but is a fixed percentage less than 100%. For high-volume equipment buyers, §179 covers the first $1.22M (2026 limit) at 100%, and bonus depreciation handles the rest at the prevailing percentage.
What qualifies
Tangible property with a recovery period of 20 years or less. This covers virtually all equipment we cover on this site: trucks, construction equipment, manufacturing tools, medical equipment, office equipment, etc.
New vs used
Unlike historical bonus depreciation (pre-2018), the current rules apply to both new and used equipment as long as it is new to your business.
