Case Study: Cost Segregation Analysis for a Single-Family Home in Iowa City, Iowa

Narrative

In 2024, the owners of a three-story single-family home in Iowa City, Iowa, sought to optimize their tax position through strategic cost segregation. The property, constructed in 2024, encompasses 1,875 square feet of living space and features modern amenities and high-quality finishes throughout.

The residence showcases contemporary design elements, including granite countertops, custom cabinetry, and energy-efficient appliances. The interior features vinyl plank flooring, ceramic tile, and multiple bathrooms with modern fixtures. The property includes a comprehensive HVAC system, modern electrical infrastructure, and various built-in amenities that enhance its functionality and value.

Objective

The primary objective of the cost segregation study was to identify and classify the residential home’s assets to optimize the owners’ tax savings. By breaking down and reallocating components into shorter depreciation life categories, ETS aimed to provide both immediate and long-term financial benefits through accelerated depreciation.

Methodology

ETS employed a detailed, engineering-based approach, which included:

1. Physical Inspection: conducting a thorough site visit to identify and photograph the property’s components
2. Document Review: examining architectural plans, construction documents and accounting records
3. Cost Analysis: applying engineering principles to allocate costs to specific asset classifications
4. Depreciation Calculation: calculating depreciation using IRS-accepted methods such as the Modified Accelerated Cost Recovery System (MACRS)

Summary

The cost segregation study for this Iowa City residence resulted in significant tax benefits through accelerated depreciation. The analysis identified 36.4% of the property’s value as qualifying for 5-year depreciation, resulting in an accumulated depreciation difference of $158,096.32 in the first year when compared to standard 39-year depreciation. This strategic reclassification provides substantial immediate tax savings and improved cash flow for the property owner while maintaining full compliance with IRS guidelines and requirements.

The study demonstrates how proper cost segregation analysis can significantly enhance the financial benefits of residential property investment through strategic tax planning.
