Cost Segregation and Depreciation Recapture
Cost segregation gets a lot of attention for the big first-year deductions it unlocks. Depreciation recapture gets far less, and that is a problem, because recapture is the bill that can come due when you sell. It does not cancel the benefit of a cost segregation analysis, but it does change the shape of it from "free money" to "a deferral with a cost at the end." Understanding how recapture works, and how accelerating depreciation into short-life assets affects it, is essential before you decide whether to run a study at all.
What depreciation recapture is
Every year you depreciate a property, you lower your taxable income and your basis in the asset drops. When you sell, the gain is measured against that reduced basis, so the depreciation you claimed effectively becomes part of your gain. Recapture is the set of rules that decides how that portion of the gain is taxed. The key point is that recapture is not an extra penalty on top of your gain, it is the government taxing back deductions you already enjoyed, often at a higher rate than the long-term capital gains rate that applies to pure appreciation.
Section 1245 vs Section 1250
The tax outcome depends on what kind of property is being recaptured, and this is exactly where a cost segregation study matters, because a study moves value from one category to the other.
| Property type | Examples | Recapture treatment |
|---|---|---|
| Section 1245 (personal property) | 5 and 7-year items: appliances, fixtures, furniture, carpet | Recaptured as ordinary income up to total depreciation taken, at your ordinary rate (up to 37% federal) |
| Section 1250 (real property) | The 27.5 or 39-year building shell | Unrecaptured Section 1250 gain, taxed at a maximum 25% federal rate |
| Gain above original cost | True appreciation on the asset | Long-term capital gain (0, 15, or 20% federal) |
Note that the 25% figure is a ceiling, not a flat rate. If your ordinary rate is below 25%, the unrecaptured 1250 gain is taxed at that lower rate instead. There is also a nuance worth flagging: some items a study classifies as 15-year land improvements, such as sidewalks and parking areas, can fall under either section depending on the asset, so the precise split between 1245 and 1250 in your study is a question for your CPA rather than a fixed rule. The broad principle holds, though. Accelerating depreciation into short-life personal property shifts recapture from the capped 1250 category toward the uncapped, higher 1245 category.
How cost segregation changes your recapture exposure
A study reclassifies a portion of the building, normally taxed as 1250 property, into 1245 personal property so you can accelerate the deductions and take bonus depreciation. That is great going in. Coming out, it means a larger slice of your depreciation sits in the 1245 bucket, which is recaptured at ordinary income rates rather than the 25% ceiling. In other words, cost segregation can trade a slower deduction taxed later at up to 25% for a faster deduction taxed later at up to 37%. Whether that trade is worth it comes down to the time value of money, the gap between your current and future tax rates, and how long you hold.
A worked example
Say you took $120,000 of accelerated depreciation through a cost seg study, split $90,000 to the 1245 personal property and $30,000 to the 1250 building component, and you now sell at a gain that covers all of it.
| Component | Amount | Rate | Approx. tax |
|---|---|---|---|
| 1245 recapture | $90,000 | Ordinary, assume 32% | ~$28,800 |
| Unrecaptured 1250 gain | $30,000 | 25% max | ~$7,500 |
| Total recapture tax | $120,000 | ~$36,300 |
The deferral still usually wins, because you used that $120,000 deduction years earlier at your then-current rate and reinvested the savings in the meantime. But the bill is real, and ignoring it is how investors get surprised at closing. See whether cost segregation is worth it for how to weigh the two.
Where recapture is reported, and the extra 3.8%
When you sell, the sale is reported on Form 4797, Sales of Business Property, which is where the recapture is separated from the rest of your gain and routed to the right rate. Two details are easy to overlook. First, the net investment income tax of 3.8% can apply on top of the recapture and capital gains for higher-income sellers, which raises the effective cost of the exit above the headline rates in the table. Second, recapture can only be as large as the gain. If you sell at a loss, there is generally no recapture because there is no gain to recharacterize, though that is rarely the scenario a cost seg investor is planning around. The practical takeaway is to look at the all-in exit rate, not just the 25% or 37% ceilings in isolation.
How a 1031 exchange defers recapture
A 1031 like-kind exchange lets you roll the proceeds of a sale into a replacement property and defer both the capital gain and the depreciation recapture. For the real property portion, Section 1031 defers the unrecaptured 1250 gain cleanly. The 1245 personal property is trickier: Section 1031 does not automatically defer 1245 recapture, and if the value of the 1245 property you give up exceeds the 1245 property in what you acquire, the difference can be taxed as ordinary income even in an otherwise clean exchange. This is one more reason the short-life components a study creates deserve careful handling when you plan an exit.
Does recapture kill the benefit?
Usually not, for three reasons:
- Time value. A deduction today is worth more than the same deduction spread over 27.5 years, even if some comes back later.
- Deferral tools. A 1031 exchange can push recapture into the future, potentially indefinitely across multiple exchanges.
- Step-up at death. Under current law, if you hold until death your heirs receive a stepped-up basis, which can eliminate the recapture altogether.
Where recapture does erode the benefit is on short holds, especially if you expect to be in a higher bracket when you sell than when you deducted. The right move is to model the full lifecycle, entry and exit, before committing. Because recapture interacts with your personal rates, your exit plan, and the specific asset mix in your study, confirm the math with a CPA before you file or sell.
Frequently asked questions
What is depreciation recapture?
It is the IRS rule that taxes the depreciation you claimed when you sell the property. Because depreciation lowered your basis, that portion of your gain is taxed, often at a higher rate than regular capital gains.
How is cost segregation depreciation recaptured?
The short-life personal property a study reclassifies is generally Section 1245 property, recaptured as ordinary income up to the depreciation taken. The building shell is Section 1250 property, taxed as unrecaptured 1250 gain at a maximum federal rate of 25%.
What is the depreciation recapture tax rate?
Section 1245 personal property is recaptured at your ordinary income rate, up to 37% federally. Unrecaptured Section 1250 gain on the building is taxed at a maximum of 25%, or your ordinary rate if it is lower.
Does a 1031 exchange defer depreciation recapture?
Yes, a like-kind exchange can defer both capital gain and recapture. The real property portion defers cleanly, but Section 1245 personal property recapture is not automatically deferred, so the asset mix must be matched carefully to avoid taxable recapture.
Does recapture make cost segregation not worth it?
Usually not. The time value of taking deductions years earlier, plus tools like 1031 exchanges and the step-up in basis at death, generally outweigh recapture. It matters most on short holds or if you expect a higher tax rate at sale.
