Cost Segregation studies are widely known to be a valuable tax planning tool for when property owners are acquiring, constructing or renovating a property. However, there are also other times that cost segregation studies can provide value that may be overlooked, such as when a step-up-in basis occurs.

One of the acceptable methods of completing a cost segregation study includes the use of statistical sampling.  According to the IRS Audit Techniques guide one method for completing a cost segregation study is utilizing a Sampling or Modeling Approach. However, there are many considerations to consider when completing a sampling review.

Many taxpayers are asking if they should delay deductions. This question is particularly relevant as taxpayers plan for the 2021 tax season, given a newly elected president and now Democrat-controlled Congress. These government changes could impact tax rates this year and, therefore, filing strategies. In his latest podcast, Dave McGuire outlines the risks, timing, and other important factors for taxpayers to consider while planning when to take deductions.

In Accounting Today, Dave highlights important specialty tax provisions inside the stimulus bill and how they may be important to businesses.

Approach & Results

The CPA firm representing the builder of newly constructed single family townhomes in West Lafayette, IN contacted McGuire Sponsel to conduct a 45L study to identify energy-efficient inclusions.

After a preliminary analysis to determine the feasibility of qualification, in less than 5 weeks our team examined 270 units and identified a number of systems that helped this project meet 45L standards, including:

  • Air conditioner is electric with a 13.0 SEER
  • Ceiling systems are R-40.0
  • Window U-Value is 0.30
  • Exterior wall systems are R-15.0


As units are newly constructed ground up, energy-efficient inclusions on developments over 50 units may qualify for a tax credit of up to $2,000 per unit through a 45L study. McGuire Sponsel professionals were able to qualify all 270 units in the maximum available credit, resulting in a total credit of $540,000 for the client.
