What Is It

Cost Segregation Accelerates Your Depreciation - Legally.

A cost segregation study reclassifies components of your building from long-life real property (depreciated over 27.5 or 39 years) into shorter-life categories (5, 7, or 15 years). This dramatically accelerates your depreciation deductions, reducing your current-year tax liability and generating immediate cash flow.

With 100% bonus depreciation reinstated after January 19th 2025, every qualifying component identified in your study can be fully deducted in Year 1. On a $2M commercial property, that can mean $400,000+ in Year 1 deductions alone.

KNOW BEFORE YOU SIGN

Eight Questions to Ask Any Cost Segregation Firm - Before You Commit to Anything.

These questions separate firms that actually do the work from firms that sell the appearance of it. A firm doing real engineering work will answer every one of these without hesitation. One that cannot — or will not — has just told you everything you need to know.

Which IRS approach number do you use — by number?

Not their marketing language. The actual number from the IRS Audit Technique Guide. Approaches 1 and 2 are the most thorough. Approaches 4 and 5 involve software estimates that fill gaps where real analysis was never performed. If they cannot give you the approach number, or use phrases like “proprietary methodology” or “best-in-class software,” you have your answer.

‍Cost Seg America: Approaches 1 and 2. Every study. No exceptions.

Can you show me a sample individual component schedule from a completed study?

A real cost segregation study produces a line-by-line component schedule — every item in the building named, quantified, individually costed, and supported by a published source citation. Ask to see one before you sign anything. If what they show you has category-level lines like “Electrical Systems — 12% of building cost” with nothing behind the number, that is a software output, not engineering analysis. Your building was never examined.

Cost Seg America will show you a sample component schedule before you commit to anything.

Where is the work performed, and who handles my private financial information?

Your study requires sharing property details, purchase price, tax information, and financial records. You have every right to know exactly who will have access to that information and where the engineering work is performed. Ask directly: is the work done in-house? Are the people performing it employees or contractors? A firm that handles your data with care will answer plainly.

Cost Seg America is 100% U.S.-based — every analyst, every study. Your information is handled by our own team, start to finish.

If the goal is to maximize my deductions — why use an approach the IRS itself says finds less?

This is the question that exposes the business model behind cheap cost segregation. You are hiring a firm to find every dollar you are legally entitled to. Approaches 1 and 2 find the most — the IRS says so in writing. If a firm is using Approach 4 or 5 instead, it is because that is faster and cheaper to produce, not because it serves you. You pay them, you take the risk, and you leave money on the table. Ask plainly: if Approaches 1 and 2 find more deductions for my property, why aren't you using them? Cost Seg America uses Approaches 1 and 2 because that is the only answer that makes sense for the client.

How many IRS audits have you defended — and what was the outcome of every one?

This is the only question in cost segregation that cannot be faked, padded, or marketed around. Ask for the exact number. Ask for the record. Ask if any client has ever been required to return money, pay penalties, or settle with the IRS because of a study the firm produced. The answer tells you more about methodology quality than any brochure or sales call ever will. Cost Seg America: 125+ IRS audits over 24 years. Zero losses. $0 ever returned on behalf of any client. Not one.

Is your fee flat and fixed — or does it change based on what you find?

A contingency fee — where the firm charges a percentage of deductions identified — creates a direct conflict of interest. The firm becomes financially incentivized to find more, not to find correctly. If the fee goes up when deductions go up, their financial interest and yours are not the same thing. Ask specifically: is the fee fixed before the study begins, or does it change based on results? Cost Seg America charges a flat fee quoted before you commit. It does not change based on findings. Our results reflect what is actually there — not what maximizes our fee.

What does your audit defense actually cover — hours, fees, and how many years out?

Many firms advertise audit support and quietly limit it to a set number of hours, a short window after delivery, or charge additional fees when the IRS actually opens a file. Ask exactly: are there hour caps? Is there a cutoff date? Are there additional fees if the IRS audits three years from now? Push for specifics, not assurances. If they hedge, you have your answer. Cost Seg America's audit defense has no hour caps, no time limits, and no additional fees. If the IRS opens your file three years from today, we are there.

How long have you been in business — and how many of your studies have actually been audited?

Years in business tells you staying power. The audit number tells you everything else. A firm that has processed thousands of studies but cannot point to meaningful IRS audit experience has never truly been tested. The firms that have survived IRS scrutiny intact are the ones that did the work correctly from the beginning. Ask how many studies they have completed, how many were audited, and the outcome each time. That ratio is the only performance metric that matters. Cost Seg America: 24 years in business. 16,000+ completed studies. 125+ IRS audits. Zero losses. $0 returned. That record was not built on marketing — it was built on methodology.
