Many business owners who invest in commercial real estate are unaware that they may be overpaying in taxes. A cost segregation study is a powerful tax planning strategy that can uncover significant savings by accelerating depreciation and improving cash flow. At Botwinick & Company, LLC, we help clients leverage this advanced approach to maximize the financial performance of their real estate investments.
What Is a Cost Segregation Study?
A cost segregation study is a detailed analysis that breaks down the components of a commercial building into different asset categories for tax purposes. Instead of treating the entire property as a single asset depreciated over 39 years, this study identifies portions of the building that can be depreciated over shorter timeframes.
By reclassifying certain building elements as personal property or land improvements, businesses can accelerate depreciation deductions, reduce taxable income in the early years, and improve overall cash flow.
Why Depreciation Timing Matters
Under standard tax rules, commercial buildings are depreciated over a 39-year period. However, many components within those buildings have significantly shorter useful lives. A cost segregation study identifies these assets and allows them to be depreciated over five, seven, or 15 years instead.
Examples of assets that may qualify for accelerated depreciation include:
- HVAC systems and related components
- Electrical and plumbing systems
- Fire protection and security systems
- Interior finishes such as drywall and flooring
- Doors, cabinetry, and fixtures
- Data cabling and communication infrastructure
Although the total depreciation taken over the life of the property remains the same, accelerating these deductions allows businesses to defer taxes and retain more capital upfront.
How Recent Tax Law Changes Enhance the Benefits
Recent updates under the One Big Beautiful Bill Act have made cost segregation even more valuable for qualifying assets placed in service after January 19, 2025.
Bonus Depreciation
The law reinstates 100% bonus depreciation for eligible assets, allowing businesses to immediately deduct the full cost of qualifying components identified through a cost segregation study. While the building itself does not qualify, many of the reclassified assets do.
Section 179 Expensing
For 2025, the maximum Section 179 deduction has increased to $2.5 million, with a phaseout beginning at $4 million in qualifying asset purchases. These thresholds are indexed for inflation, increasing to $2.56 million and $4.09 million in 2026. Again, while the structure itself is excluded, many segregated components may qualify for immediate expensing.
Qualified Production Property Deduction
For businesses involved in manufacturing or certain agricultural operations, a new provision allows a 100% deduction for qualified production property. To qualify, construction must begin after January 19, 2025, and before January 1, 2029, with the property placed in service before 2031.
This deduction can significantly reduce the need for cost segregation in some cases, but it comes with strict requirements and limitations. Careful evaluation is necessary to determine the best approach.
Is a Cost Segregation Study Right for You?
Cost segregation is not a one-size-fits-all strategy. The benefits depend on factors such as property type, purchase price, renovation costs, and your overall tax situation. When executed properly, it can provide substantial short-term tax savings and improved liquidity.
However, the IRS closely reviews these studies, and improper classifications can lead to challenges. That’s why it’s critical to work with experienced professionals who understand both the engineering and tax aspects of the process.
