Unlocking Hidden Value: The Power of Cost Segregation Studies
A cost segregation study is a tax strategy that accelerates depreciation deductions on real estate by reclassifying building components into shorter recovery periods.
Cost segregation can be a valuable strategy for real estate owners looking to improve cash flow and optimize tax benefits in the current tax year. By identifying building components that qualify for shorter depreciation periods, property owners may be able to accelerate deductions and reduce taxable income.
This article explains the basics of cost segregation, how a cost segregation study works, when property owners should consider one, and what makes KBKG’s approach to cost segregation studies valuable.
Key Takeaways
- Cost segregation studies accelerate depreciation by reclassifying building components into shorter recovery periods.
- Cost segregation studies typically reclassify 15–45% of a building’s depreciable basis, depending on property type and construction.
- A well-documented cost segregation study should combine detailed engineering analysis, sound tax technical expertise, and comprehensive, audit-ready documentation.
What Is Cost Segregation?
Cost segregation, often called “cost seg,” is a tax planning strategy used by property owners and real estate investors to accelerate depreciation deductions in the current tax year. Instead of treating a property as one building asset with a single depreciation schedule, cost segregation breaks the property into separate components, each with its own recovery period.
Reclassifying qualifying assets into shorter depreciation categories can increase deductions in the earlier years of ownership. This may improve cash flow and reduce current tax liability.
What Is a Cost Segregation Study & How Does It Work?
A cost segregation study identifies and reclassifies certain assets within a real estate investment, including personal property and land improvements. These assets may qualify for shorter depreciation periods, such as 5, 7, or 15 years, instead of the standard 27.5-year or 39-year depreciation periods used for residential and commercial buildings.
A typical cost segregation study includes a detailed analysis performed by qualified professionals with engineering, construction, and tax knowledge.
The IRS Cost Segregation Audit Techniques Guide from the Internal Revenue Service (IRS) outlines the standards and methodologies accepted for these studies.
Asset Category | Typical Recovery Period |
Personal Property | 5–7 years |
Land Improvements | 15 years |
Building Structure | 27.5 years (residential) / 39 years (commercial) |
The Four Steps of a Cost Segregation Study
The study involves a detailed analysis conducted by engineering, construction, and tax regulation professionals. Here’s how it works:
- Property Review and Inspection: The process begins with a review of the property and available documentation to identify building components and improvements that may qualify for accelerated depreciation.
- Cost Analysis and Allocation: Property costs are analyzed and allocated among the building structure, land improvements, personal property, and other applicable asset categories.
- Asset Classification: Each identified component is classified under applicable tax rules and assigned the appropriate depreciation recovery period.
- Tax Reporting and Documentation: The findings are documented in a comprehensive cost segregation report that supports the resulting depreciation deductions and provides substantiation in the event of an IRS examination.
A Real-World Example
For one real estate portfolio with 585 owned locations and approximately $40 million in cost basis, KBKG used an IRS-approved statistical sampling approach to perform detailed engineering analysis on 48 representative locations.
KBKG reclassified nearly $8 million into shorter depreciation categories, helping the client claim more than $5 million in additional first-year deductions.
When Should You Conduct a Cost Segregation Study?
Timing is crucial when considering a cost segregation study. While you can perform it at any point during your ownership, conducting it early in the acquisition or construction phase offers the most significant advantages. These are all scenarios where you should consider a cost segregation study:
- New Property Construction or Acquisition: If you build or acquire a new property, conducting a cost segregation study during construction or soon after purchasing can optimize tax benefits from the outset.
- Renovations and Improvements: A cost segregation study can help identify and depreciate these changes separately if you’re planning substantial property renovations or improvements.
- Tax Planning: As part of your overall tax planning strategy, you can conduct a cost segregation study to enhance cash flow and reduce tax liability.

Cost segregation can help property owners accelerate depreciation, improve near-term cash flow, and make more capital available for property improvements, debt reduction, or future investments. Whether the strategy is worthwhile depends on the property’s basis, asset mix, placed-in-service date, and the owner’s tax position.

Frequently Asked Questions
Is a cost segregation study worth it?
A cost segregation study may be worth it when the value of accelerated depreciation is greater than the cost of completing the study and the property owner can utilize the additional deductions. The potential benefit depends on the property type, building basis, asset mix, tax position, and expected holding period. A preliminary savings analysis can help an owner decide whether to move forward.
How much can a cost segregation study save?
There is no fixed savings amount because every property and taxpayer is different. Cost segregation does not create new depreciable basis; it identifies eligible property costs that may be deducted sooner, potentially increasing early-year deductions and improving cash flow. Property owners can use KBKG’s cost segregation calculator or request a preliminary analysis to estimate the potential benefit.
Who qualifies for a cost segregation study?
Owners of income-producing residential or commercial real estate may qualify for cost segregation. Common property types include apartment buildings, offices, retail properties, restaurants, hotels, warehouses, medical facilities, self-storage facilities, manufacturing buildings, and short-term rentals. The property’s basis, components, placed-in-service date, and the owner’s tax situation help determine whether a study is likely to be worthwhile.
