Cost segregation studies are creating quite a buzz in 2025 as a popular tax strategy for property owners looking to speed up their depreciation deductions and boost their cash flow. However, some investors are worried that purchasing and leveraging such a study could raise their chances of getting audited by the IRS.
Let’s take a closer look at how to buy a cost segregation study that minimizes audit risk and aligns with IRS guidelines.

IRS Perspective on Cost Segregation
The IRS sees cost segregation as a valid tax strategy, as long as it's done correctly. In fact, they've put together an Audit Techniques Guide (ATG) that specifically addresses cost segregation studies, detailing the methods and documentation needed to stay compliant. This shows that the IRS doesn't automatically consider cost segregation studies as potential audit triggers.
