Definition
Cost segregation is a tax strategy used in real estate investing that reclassifies portions of a property’s purchase price into shorter-lived depreciation categories (such as 5, 7, or 15 years) rather than the standard 27.5-year (residential) or 39-year (commercial) schedule.
How It Works
When a property is purchased, the total price (excluding land) is normally depreciated over a long recovery period. A cost segregation study identifies components such as flooring, appliances, lighting, cabinetry, parking lots, and certain improvements that qualify for shorter depreciation lives.
These reclassified components may also qualify for bonus depreciation, allowing significant first-year deductions.
Example
An investor purchases a commercial building for $5,000,000. After allocating land value, $4,000,000 remains depreciable.
- Standard method: $4,000,000 depreciated over 39 years
- With cost segregation: $1,000,000 reclassified into 5- and 15-year property
The accelerated portion may qualify for bonus depreciation, resulting in substantial first-year tax savings.
Why Investors Use It
- Increase early-year tax deductions
- Improve after-tax cash flow
- Enhance projected IRR
- Offset passive income (subject to tax rules)
When It Makes Sense
- Large acquisition price
- High taxable income to offset
- Long-term hold strategy
- Ability to leverage bonus depreciation
Depreciation Recapture Considerations
Accelerated depreciation increases potential depreciation recapture taxes upon sale. While cost segregation improves early cash flow, investors should evaluate the full lifecycle tax impact.
Investor Perspective
Cost segregation is a powerful tool, but it does not create economic value by itself. It accelerates tax benefits — it does not increase NOI or operational performance. Strong investments stand on fundamentals first.
Common Pitfalls
- Failing to perform a professional study
- Ignoring recapture at exit
- Assuming bonus depreciation will remain unchanged
- Overvaluing tax savings in underwriting
