Bonus Depreciation
An additional first-year depreciation allowance for qualifying property, currently phasing down through 2027.
Bonus depreciation was 100% from 2018–2022, then phasing down: 80% (2023), 60% (2024), 40% (2025), 20% (2026), 0% (2027). Unlike Section 179, bonus depreciation has no income limit and can create a loss.
Cost-segregation studies on real estate typically use bonus depreciation to accelerate deductions on the building components reclassified to shorter MACRS lives.
