The Role of Engineers in Cost Segregation

ASCSP • July 24, 2024

The History of Cost Segregation

Imagine uncovering hidden tax savings amounting to tens or even hundreds of thousands of dollars—savings that can be reinvested into your business, property improvements, or other ventures.


Take, for example, a commercial property owner who recently conducted a cost segregation study and discovered $250,000 in tax savings over a few years. This was made possible by  identifying and reclassifying building components, accelerating their depreciation schedules. Such outcomes are achievable with the right expertise and approach.


At the heart of every successful cost segregation study are skilled engineers. These professionals bring technical knowledge and analytical precision, making them indispensable to the process. Engineers analyze building components, ensuring that every eligible item is identified and reclassified correctly. Their role is crucial in navigating the complexities of IRS guidelines and securing maximum tax benefits for property owners.


In this blog post, we will explore the basics of cost segregation and the indispensable role engineers play in this process. By the end, you'll understand why partnering with experienced engineers is essential for unlocking the full potential of cost segregation.

The Basics of Cost Segregation

Cost segregation is a tax strategy that allows property owners to accelerate depreciation deductions by reclassifying certain building components. Instead of depreciating the entire property over the standard 27.5 or 39-year period, cost segregation identifies specific assets within the property that can be depreciated over shorter lifespans, typically 5, 7, or 15 years. This reclassification results in larger depreciation deductions in the earlier years of property ownership, thereby reducing taxable income and increasing cash flow.

Process Overview

The process of a cost segregation study involves several key steps:


  1. Initial Assessment: A preliminary review of the property is conducted to determine if a cost segregation study will be beneficial.
  2. Data Collection: Detailed information about the property, including construction costs, blueprints, and invoices, is gathered.
  3. Site Inspection: Engineers visit the property to identify and document the various components and systems.
  4. Cost Allocation: Each building component is analyzed and reclassified into appropriate depreciation categories.
  5. Report Preparation: A comprehensive report is prepared, detailing the findings and providing the necessary documentation to support the reclassifications.
  6. Implementation: The report is used to adjust depreciation schedules and amend tax returns if necessary, ensuring compliance with IRS guidelines.


Conducting a cost segregation study not only maximizes tax benefits but also ensures that property owners are leveraging all available resources to optimize their financial strategies.

Engineers and Cost Segregation

Technical Expertise

Engineers play a role in cost segregation studies due to their specialized knowledge and skills. Their background in construction, architecture, and engineering equips them with the technical expertise needed to dissect a building into its component parts.


This deep understanding allows engineers to identify which assets qualify for accelerated depreciation and to accurately assess their value. Their ability to interpret construction documents, blueprints, and specifications is crucial in ensuring every eligible component is properly classified. Each of these asset categories can benefit significantly from the accelerated depreciation schedules afforded by cost segregation.

Methodology

The methodology engineers employ in a cost segregation study is both systematic and thorough. It involves:



  1. Detailed Property Analysis: Engineers conduct a comprehensive review of the property, examining all physical aspects and documentation, including construction costs, architectural plans, and detailed invoices.
  2. Component Identification: They identify and categorize all building components into various asset classes, such as land improvements, personal property, and real property.
  3. Cost Allocation: Using their technical expertise, engineers allocate costs to each component based on construction cost data and industry standards. This involves determining the remaining useful life of assets and applying appropriate depreciation schedules.
  4. Documentation: Engineers meticulously document their findings, creating detailed reports that outline the reclassification of assets and the rationale behind each decision.

Accuracy and Compliance

Precision is critical in cost segregation studies, and engineers ensure that the reclassification of assets complies with IRS guidelines. Accurate classification not only maximizes tax benefits but also minimizes the risk of an IRS audit. Engineers' attention to detail and adherence to regulatory standards are essential in producing reliable and defensible cost segregation reports.


Their thorough documentation and methodological approach provide the necessary support for property owners to confidently implement the study's findings in their tax filings, ensuring compliance and optimizing tax savings. By leveraging the specialized skills of engineers, property owners can be assured that their cost segregation studies are both accurate and compliant, leading to substantial financial benefits and peace of mind.

Diverse Property Types

Engineers must tailor their approach to cost segregation studies to accommodate the unique characteristics of different property types. Each type of property—whether commercial, residential, or industrial—presents distinct challenges and opportunities for asset reclassification. Here’s how engineers adapt their methodologies to suit various property categories:

Commercial Properties

For commercial properties such as office buildings, retail spaces, and hotels, engineers focus on identifying assets that can be classified as personal property or land improvements. This includes items like carpeting, lighting fixtures, signage, and landscaping.



  • Personal Property: Engineers identify movable items and fixtures that can be depreciated over shorter periods.
  • Land Improvements: Elements like parking lots, sidewalks, and landscaping are reclassified to benefit from accelerated depreciation schedules.

Residential Properties

In residential properties, such as apartment complexes and rental homes, engineers look for opportunities to reclassify common area components and building systems.


  • Common Areas: Components like clubhouses, pools, and recreational facilities can often be depreciated more rapidly.
  • Building Systems: Engineers analyze systems such as HVAC, plumbing, and electrical systems to determine which elements qualify for shorter depreciation periods.

Industrial Properties

Industrial properties, including manufacturing plants and warehouses, often contain specialized equipment and unique structural components that can be reclassified.


  • Specialized Equipment: Engineers focus on machinery, production lines, and specialized electrical systems that support manufacturing processes.
  • Structural Components: Structural elements unique to industrial operations, such as reinforced flooring and heavy-duty ventilation systems, are examined for potential reclassification.

Mixed-Use Properties

Mixed-use properties combine elements of commercial, residential, and industrial spaces, requiring a more complex and nuanced approach.


  • Zoning and Usage: Engineers must consider zoning laws and the intended use of different areas within the property to accurately classify assets.
  • Integrated Systems: Shared systems serving multiple functions (e.g., commercial kitchens, combined heating/cooling systems) are analyzed for optimal classification.

Adaptation and Customization

To effectively manage these diverse property types, engineers employ a customized approach that includes:


  • On-Site Inspections: Conducting thorough site visits to observe and document the specific features and uses of the property.
  • Detailed Cost Breakdown: Reviewing detailed cost records and construction documents to ensure accurate allocation of costs.
  • Collaboration: Working closely with property owners, architects, and contractors to gather comprehensive information and insights.


By adapting their strategies to the specific needs of each property type, engineers ensure that cost segregation studies are accurate, compliant, and maximally beneficial, providing property owners with significant tax savings and optimized financial outcomes.

Authors: Alex Bagne, JD, CPA, MBA, CCSP, President – ICS Tax, LLC David Ontaneda, CCSP, Director of Cost Segregation Services – ICS Tax, LLC The IRS Large Business and International (LB&I) division has released updated Practice Units titled "Identifying a Taxpayer Electing a Partial Disposition of a Building" and "Examining a Taxpayer Electing a Partial Disposition of a Building." These resources aim to guide IRS examiners in recognizing and assessing instances where taxpayers elect a partial disposition of a building or its structural components. While these Practice Units serve as valuable tools for understanding tax concepts and specific transactions, they are not official pronouncements of law and should not be cited as such. Understanding Partial Disposition A partial disposition occurs when a taxpayer disposes of a portion of an asset rather than the entire asset. This can happen during renovations or improvements when parts of the building are replaced or retired. For example, a taxpayer upgrading to energy-efficient LED lighting, installing a new HVAC system, replacing an aging roof, or demolishing old tenant improvements can elect a partial disposition to write off the remaining value of the removed assets in the year of disposal. Electing a partial disposition allows taxpayers to recognize a loss on the disposed portion in the year the disposition occurs. This election is made by reporting the loss on a timely filed original tax return for the taxable year in which the disposition took place. No specific form or statement is required to be attached to the return. Importance in Tax Planning Electing a partial disposition offers several tax planning advantages: Accelerated Loss Recognition : Taxpayers can claim a loss on the disposed portion of the asset in the year of disposition, potentially reducing taxable income. Avoidance of Depreciation Recapture : By recognizing the disposition, taxpayers can prevent continued depreciation of the replaced component, which could lead to depreciation recapture issues upon the sale of the entire asset. Accurate Basis Tracking : It ensures that the asset's basis is adjusted to reflect the removal of the disposed component, maintaining accurate records for future depreciation and disposition calculations. Facilitating Partial Dispositions through Cost Segregation Cost segregation is a tax strategy that involves identifying and reclassifying components of a building into shorter recovery periods for depreciation purposes. A thorough cost segregation study can: Identify Specific Components : By breaking down the building into individual components, taxpayers can more easily determine which parts are being disposed of during renovations. Assign Accurate Costs : Each component is assigned a cost basis, facilitating the calculation of the adjusted basis for the disposed portion. Simplify Basis Adjustments : With detailed records from the cost segregation study, taxpayers can accurately reduce the asset's basis by the disposed portion's adjusted basis, as required by the disposition regulations. By integrating cost segregation studies into their tax planning, taxpayers can effectively manage partial dispositions, ensuring compliance with IRS regulations and optimizing tax benefits.
