Cost segregation is a tax strategy that accelerates depreciation deductions by reclassifying components of a building into shorter depreciation schedules. Instead of depreciating the entire building over 27.5 years, a cost segregation study identifies components that can be depreciated over 5, 7, or 15 years, creating significantly larger tax deductions in the early years of ownership.
How it works
A standard $500,000 residential rental (75% building value = $375,000) generates $13,636/year in straight-line depreciation. With a cost segregation study, 20-40% of the building value might be reclassified into shorter-lived categories:
| Component | Value | Life | Year 1 Deduction |
|---|---|---|---|
| 5-year property (appliances, carpet, fixtures) | $56,250 | 5 years | $11,250 |
| 7-year property (cabinets, certain finishes) | $37,500 | 7 years | $5,357 |
| 15-year property (land improvements, parking) | $37,500 | 15 years | $2,500 |
| 27.5-year property (remaining structure) | $243,750 | 27.5 years | $8,864 |
| Total Year 1 Deduction | $27,971 |
Compared to $13,636 with straight-line depreciation, cost segregation more than doubles the first-year deduction. At a 24% tax bracket, the additional $14,335 deduction saves $3,440 in year-one taxes.
When cost segregation makes sense
- Properties valued at $500,000+: The study costs $5,000-$15,000, so the property value needs to be high enough to generate savings that exceed the cost.
- Major renovations: Renovation costs can be segregated just like the original building.
- High-income investors: The tax savings are proportional to your tax bracket. Higher brackets benefit more.
- Real Estate Professionals: REPS can use depreciation losses against all income, making cost segregation even more powerful.
The cost segregation study
A qualified engineer or CPA firm conducts the study by examining the property (physically or from construction documents) and classifying each component into the appropriate depreciation category. The report is your documentation for the IRS. Cost: $5,000-$15,000 for residential, $10,000-$25,000 for commercial.
