The step-down
Bonus depreciation lets you deduct a percentage of eligible short-life property in the first year. That percentage has been stepping down (for example 80% in 2023, 60% in 2024, 40% in 2025, 20% in 2026), though legislation can change the schedule.
Why it matters for cost segregation
The bonus rate is applied to the assets a cost segregation study reclassifies. A lower bonus rate means a smaller first-year deduction, so timing a study and a purchase around the schedule affects your savings.
Confirm the current rate
Because Congress periodically revises these rules, always confirm the rate for your placed-in-service year. The cost segregation calculator lets you enter the exact bonus percentage.
Frequently asked questions
What is the bonus depreciation rate now?
It phases down annually (e.g., 60% in 2024, 40% in 2025, 20% in 2026). Confirm the current year's rate, as legislation can change it.
Does bonus depreciation apply to the whole building?
No — mainly to the shorter-life components a cost segregation study separates out.
