Hire Cost Segregation Providers That Use Certified Engineers

When real estate investors first learn about cost segregation studies, the conversation usually starts with tax savings. And rightfully so, accelerating depreciation can bring significant cash flow that transform investment returns.


But what often gets overlooked in that initial excitement of hiring a cost segregation provider... not all providers are created equal.


The IRS has made it clear that the quality of your cost segregation study matters. And at the core of this issue is one crucial, non-negotiable element: the involvement of qualified engineers.

The Engineering Gap in Cost Segregation


A cost segregation study is fundamentally an engineering exercise that happens to have tax implications, not the other way around. The process requires detailed analysis of construction documents, site visits, understanding of building materials, and the ability to properly classify components based on their function and permanence.


When you compare studies done by CPA firms that only use estimation software and generic templates, the difference is clear. While having tax knowledge is definitely important, it can't replace the need for genuine engineering analysis. The IRS is aware of this and is paying closer attention to studies that don't have proper engineering backing.



What the IRS Actually Expects


The IRS Audit Techniques Guide for cost segregation specifically emphasizes the importance of qualified professionals.

When you hire a provider without certified engineers, you're essentially gambling that the IRS won't look too closely. Do you really want to roll the dice with your financial future?



What Certified Engineers Bring to the Table


Engineers with proper certifications (industry-specific credentials) bring irreplaceable value:


Technical Expertise

They understand building systems, construction methods, and how components interact. This isn't something you learn from a tax course.

Credibility Under Scrutiny

When an IRS agent sees a study signed by a licensed Professional Engineer, it immediately carries weight.

Accurate Classifications

Engineers can properly distinguish between structural elements and personal property, understand functional use, and apply the correct depreciation categories based on technical merit.

Defensible Documentation

They know how to document their analysis in a way that withstands technical questioning, not just tax questioning.



What to Ask Prospective Cost Seg Providers


Before you hire a cost segregation firm, ask these questions:


  • Who will actually perform the engineering analysis on my property?

  • What are their specific credentials and licenses?

  • Will someone visit my property in person?

  • Can I see a sample report showing the level of detail provided?

  • What percentage of your studies have been audited, and what was the outcome?

  • Do your engineers sign and seal the study?


The answers will reveal all you need to determine if they're qualified to protect your interests.




Red Flags to Watch For When Hiring Cost Segregation Professionals


When evaluating providers, be wary if:


🚩 They don't mention engineers at all in their marketing

🚩 The study is prepared entirely by accountants or tax professionals

🚩 There's no site visit included in the standard process

🚩 The price seems too good to be true (quality engineering isn't cheap)

🚩 They can't provide information about their engineers' credentials

🚩 The deliverable is a simple spreadsheet rather than a detailed report




The True Cost of a Failed Audit


Here's what happens when a poorly-prepared cost segregation study gets challenged by the IRS:


  1. Disallowed deductions going back multiple years

  2. Interest and penalties on the additional tax owed

  3. Professional fees to fight the audit or amend returns

  4. Time and stress dealing with the audit

  5. Potential recapture of depreciation already taken


The "savings" from a cheaper study evaporates quickly when the IRS comes knocking.



When You Hire Cost Segregation Providers


Cost segregation can be an incredibly effective tax strategy, but it’s important to get it right. While the tax code does allow for accelerated depreciation, it doesn’t automatically guarantee it.


Your cost segregation study should really be a detailed engineering document that aligns with IRS standards. Plus, it could serve as your main line of defense if you ever face an audit. Wouldn't you feel more confident defending a study crafted by an ASCSP certified engineer who can clearly explain their findings to the IRS?


In the era of 100% Bonus Depreciation, it's safe to say that IRS enforcement and scrutiny are on the rise. That's why you should hire cost segregation providers that employ certified engineers, it is essential for getting it right from the start.


Choose wisely. Your future self will thank you.
