One asset, 39 years, no questions asked.
By default, the IRS looks at a building and sees a single 39-year asset. On a $1,196,301 industrial property in Loomis, that view would have released the owner's deductions in equal, unhurried pieces, near $31,000 each year, stretched across the better part of a lifetime.
There is nothing improper about the long schedule. It is simply the assumption you inherit if no one looks closer. And the tax code plainly invites a closer look: MACRS assigns different recovery periods to different kinds of property, and a great deal of what makes up a building was never 39-year property to begin with.
So the real question is never whether the deductions exist. It is when you get them. Slowly, over 39 years, or largely now. For this property, the gap between those answers runs to millions.
With industrial, the site often tells the story.
An industrial or warehouse property leans heavily on its shell, so it can reclassify a smaller share than a fitted-out building. The value that does accelerate tends to live in the site work and the electrical that serves equipment.
The Cost Seg America team analyzed this property the way the two engineering approaches the IRS ranks highest call for: component by component, across the whole property. Not a questionnaire, not a software estimate that runs the address through a template and returns an average. An actual engineering analysis of the structure, the site work, and the systems that a cheaper study never bothers to separate.
What an engineered study looks for in a property like this
- Site work and land improvements: paved yards, parking, truck courts, site lighting, and landscaping.
- Dedicated electrical serving equipment and process loads, distinct from base building power.
- Specialty plumbing and systems supporting operations rather than the structure.
- Non-structural interior improvements where present.
The result: $445,000, roughly 37% of the property's basis, was identified as shorter-life property and moved off the 39-year schedule into faster federal depreciation. That is not an estimate or a projection. It is what an engineered analysis documented on this building, to the standard the IRS publishes for its own examiners in the Cost Segregation Audit Techniques Guide.
You were always owed it. Now you get it sooner.
A study does not add a single deduction. The full $445K was the owner's all along. What it did was rearrange the timing, moving deductions the code had scheduled for later into the here and now.
Timing is the entire advantage. A dollar you deduct today can earn for you today; a dollar you deduct in 2050 has already lost ground to inflation and to every opportunity you passed up while waiting. That is why moving $445K forward is worth doing, it is a head start the tax code grants on purpose, and it costs nothing to take.
Current law only helps. Under the One Big Beautiful Bill Act, signed July 4, 2025, 100% bonus depreciation is permanent for qualifying property placed in service after January 19, 2025. Because an engineered study isolates exactly the property that qualifies, a result like this can be claimed in the first year rather than spread thin over the building's life.
What accelerating $445K is worth.
Reclassifying property is only half the story. The other half is what those accelerated deductions are worth once they are working for you now instead of decades from now. The figures below are illustrative, calculated from this study's real reclassified amount using the assumptions shown.
Illustrative first-year federal tax benefit: $164,650. Illustrative 10-year net present value of accelerating: $136,321.
Illustrative only, not a promise of results. First-year benefit assumes the $445K of reclassified property is deducted in year one under 100% bonus depreciation (permanent under the One Big Beautiful Bill Act for qualifying property placed in service after January 19, 2025) at a 37% federal tax rate. Net present value compares taking those deductions now versus the default schedule, discounted at 8% over 10 years. Federal figures only. Your actual benefit depends on your tax situation; your CPA determines what applies to you.
What owners ask about a result like this.
Can this still work on a property I have owned for a while?
It can. A look-back study applies to property bought, built, or renovated within the past ten years or so. The mechanism is one form, Form 3115, filed with your normal return, and the depreciation you should already have claimed comes back in a single year as a Section 481(a) catch-up. No amended returns, no reopening the past.
Does claiming this much put a target on the return?
No more than any well-built study. Cost segregation is IRS-documented, with its own examiner manual in Publication 5653, and examinations turn on the strength of the work. Every Cost Seg America study uses the two engineering approaches that manual ranks highest, and the record stands at 125-plus audits, zero losses, zero dollars returned.
And when the building eventually sells?
Depreciation always factors into a sale, cost segregation or not, and your CPA accounts for it in advance. For long-term holders, the benefit of big deductions now generally outweighs the treatment at exit, and a 1031 exchange can defer it entirely. This is a planning conversation, not a reason to hold back.
Should I expect the same 37% on my building?
Not automatically. The reclassified share reflects how the property was built and fitted and how much surrounds it outside, so the numbers move a lot from one building to the next. An engineered analysis settles it, and a free proposal will estimate yours before any commitment.
