How Much Does a Cost Segregation Study Cost? (2026)

If you're a real estate investor or commercial property owner, you've probably heard that a cost segregation study can slash your tax bill. The next question is always the same: what does it actually cost?

Here's the direct answer. At National Cost Segregation LLC, a study costs $2,100 — flat. No tiers. No percentage of your savings. No "request a custom quote" runaround. You know the price before you pick up the phone.

Why most firms won't give you a straight number

Search around and you'll find two extremes. Traditional engineering firms often charge $5,000 to $15,000 per study and price by property size and complexity — so you can't know your cost without a sales call. On the other end, you'll find $495 "software" studies where you upload photos and a program spits out a report.

We built our pricing to cut through all of it. $2,100, flat, with a real study behind it. That's affordable enough for a single rental and serious enough for a commercial building.

The ROI math (this is the part that matters)

The cost of the study is almost beside the point once you see the return.

Say you own a $1,000,000 commercial building (excluding land). Normally you'd depreciate that over 39 years — about $25,600 per year. Slow.

A cost segregation study typically reclassifies 20–35% of the building's basis into 5-, 7-, and 15-year schedules. Take the middle — say 28%, or $280,000 — moved into short-life assets.

With 100% bonus depreciation now permanent under the One Big Beautiful Bill Act, much of that $280,000 can be deducted in year one rather than spread across four decades.

If you're in a combined 35% marginal tax bracket, deducting an extra ~$280,000 sooner can defer roughly $98,000 in taxes into your pocket now, where you can reinvest it. Against a $2,100 study, that's a return of well over 40 to 1.

Even a modest $300,000 rental usually produces tens of thousands in accelerated deductions. The study pays for itself many times over in the first year.

Why the cheap $495 studies are risky

If a $495 report saves you the same taxes, why pay more? Because of what happens if the IRS ever looks.

Cheap studies are software-only. You upload some photos and floor plans, and an algorithm estimates component values. Nobody ever sets foot on the property. In an audit, the first question is: *how did you arrive at these numbers?* "A website estimated it" is not a strong answer. The IRS's own Cost Segregation Audit Techniques Guide favors studies grounded in real, documented methodology.

That's exactly why every National Cost Segregation study includes a live, on-site inspection by a licensed appraiser. Our founder, Mike Baldwin, is a Certified General Appraiser licensed in 11 states, an MAI candidate, and a licensed real estate broker. We physically document your components, so if anyone asks how a number was derived, we have evidence — not an algorithm's guess.

Think of it this way: a $495 study that gets disallowed in an audit isn't cheap. It's the most expensive study you'll ever buy.

What you get for $2,100

• A live, on-site inspection by a licensed appraiser
• Reclassification of building components into 5-, 7-, and 15-year schedules
• A documented, audit-ready report your CPA can use directly
• Depreciation schedules and full asset detail
• Methodology aligned with IRS guidance

Is it worth it for your property?

If your building is worth roughly $200,000 or more, it's almost always worth at least a conversation. And you don't have to have bought it this year — using Form 3115, we can help you catch up missed depreciation on properties you've owned for years, often as one big current-year deduction.
