Cost Segregation and Bonus Depreciation: What to Check First
Cost segregation can interact with bonus depreciation, but the result depends on placed-in-service timing, property facts, current law, and tax limitations.
Direct answer
Cost segregation can identify shorter-life property that may be eligible for bonus depreciation if the law and facts support it. The benefit depends on placed-in-service dates, property type, basis, tax law in effect for the year, and whether the taxpayer can use the deductions.
Because bonus depreciation rules have changed over time, do not rely on an old article or calculator without checking current IRS guidance.
What to verify first
Before modeling bonus depreciation, collect:
- Purchase or improvement date.
- Placed-in-service date.
- Whether the property is new to you or self-constructed.
- Building basis after land allocation.
- Improvement invoices and completion dates.
- Prior depreciation method.
- Passive activity and income facts.
Why cost segregation affects bonus depreciation
Cost segregation separates building costs from shorter-life assets where supportable. Bonus depreciation may apply to certain qualifying property. If a component is properly classified as eligible short-life property, the timing of deductions can change materially.
That does not mean every cost segregation result creates usable tax savings. Passive activity limits, basis limits, at-risk limits, state conformity, and sale plans can change the practical outcome.
