Understanding Cost Segregation
Cost segregation is a strategic tax planning tool that allows property owners to accelerate depreciation deductions by identifying and reclassifying personal property assets and land improvements that are typically buried in real property.
Key Benefits
- Accelerate depreciation from 39/27.5 years to 5, 7, or 15 years
- Generate significant cash flow through tax savings
- Catch-up depreciation for properties placed in service in prior years
- Maximize bonus depreciation on qualified assets
- Reduce property tax assessments in some jurisdictions
Typical Asset Reclassifications
- 5-Year Property: Carpeting, window treatments, decorative fixtures, specialized electrical/plumbing
- 7-Year Property: Furniture, equipment, data/voice wiring
- 15-Year Property: Site improvements, landscaping, parking lots, exterior lighting
- 39-Year Property: Building structure, general electrical/plumbing, HVAC
Ideal Properties
- Purchase price or construction cost over $750,000
- Renovation projects over $500,000
- Properties with significant personal property or land improvements
- Manufacturing facilities, hotels, medical facilities
- Properties purchased in the last 15 years (look-back studies)
Important Considerations
- Engineering-based studies provide the most defensible position
- Study costs are typically tax deductible
- Depreciation recapture applies on sale (but at capital gains rates for bonus depreciation)
- State depreciation rules may differ from federal
- Passive activity loss rules may limit current year benefits
đź“… 2025 Bonus Depreciation Phase-Out Schedule
| Tax Year | Bonus Rate | $2M Property Example | Impact |
|---|---|---|---|
| 2022 & Prior | 100% | $460K first-year deduction | Full immediate expensing |
| 2023 | 80% | $368K first-year deduction | Phase-out begins |
| 2024 | 60% | $276K first-year deduction | Act now for best benefits |
| 2025 | 40% | $184K first-year deduction | Significant reduction |
| 2026 | 20% | $92K first-year deduction | Last year of bonus |
| 2027+ | 0% | Standard MACRS only | No bonus depreciation |
⚠️ Action Required: Properties placed in service in 2024-2025 still qualify for significant bonus depreciation. Consider accelerating acquisitions or completing cost segregation studies before rates drop further.

Frequently Asked Questions
What is cost segregation and how does it save taxes?
Cost segregation is an IRS-approved tax strategy that accelerates depreciation deductions for commercial real estate. Instead of depreciating the entire building over 39 years (27.5 for residential), an engineering study identifies components that qualify for 5, 7, or 15-year depreciation. This front-loads deductions, reducing taxable income in early years and improving cash flow. A $2M property might generate $150K-$300K in first-year tax savings.
When is the best time to do a cost segregation study?
The best time is the year you acquire or construct the property to maximize bonus depreciation benefits. However, "look-back" studies can be done on properties acquired in prior years—you can claim missed depreciation in a single year without amending returns (IRS Form 3115). With bonus depreciation phasing out (40% in 2025, 20% in 2026, 0% in 2027), acting sooner captures higher benefits.
How much does a cost segregation study cost?
Professional cost segregation studies typically cost $5,000-$30,000 depending on property size and complexity. A $2M apartment building might cost $10K-$15K for a study. The ROI is usually 5-10x the study cost in first-year tax savings alone. Study fees are tax-deductible as a business expense. Always use a qualified firm with engineering expertise—IRS audits favor engineering-based studies over estimates.
What is depreciation recapture and should I be concerned?
When you sell the property, accelerated depreciation is "recaptured" and taxed. However, this is often advantageous: (1) You've had use of the tax savings for years (time value of money), (2) Recapture on bonus depreciation is taxed at capital gains rates (0-20%), not ordinary income rates (up to 37%), (3) A 1031 exchange defers all recapture. The present value of early deductions typically far exceeds the future recapture cost.
Can I do cost segregation on a property I've owned for years?
Yes! "Look-back" studies allow you to claim missed depreciation on properties acquired in prior years. Using IRS Form 3115 (Change in Accounting Method), you can take all the catch-up depreciation in a single year without amending prior returns. This is particularly valuable for properties acquired 2017-2022 when 100% bonus depreciation was available. There's no statute of limitations on look-back studies.
What's the minimum property value for cost segregation to make sense?
Generally, cost segregation is worthwhile for properties with a depreciable basis (purchase price minus land) of $750,000 or more. For smaller properties, the study cost may not justify the benefits. However, some firms offer "desktop" studies for $500K-$750K properties at lower cost. Renovation projects over $500K can also benefit. The higher your tax bracket, the more valuable the deductions become.
