What Happens When You Sell a Property After a Cost Segregation Study? Understanding Depreciation Recapture

She bought the medical office building in Mission Valley five years ago. She commissioned a cost segregation study, front-loaded more than $180,000 in depreciation over the first two years, and watched her taxable income from the property shrink substantially. It felt like the right move then, and it was.

Now she is selling. The buyer made an offer she cannot ignore. And the question she did not ask five years ago is the one she needs answered today: what happens to all that accelerated depreciation when the property changes hands?

The short answer is that most of it comes back as taxable income in the year of sale. The longer answer — how much, at what rate, and what you can do about it — is worth understanding before you sign the closing statement. If you are wondering whether a cost segregation study is worth starting with, the answer is still yes — but only when you understand the full picture.

What Depreciation Recapture Actually Is

When you own a rental or commercial property, the IRS lets you deduct a portion of the building's cost every year as depreciation. It is a paper expense that reduces your taxable income without costing you cash. The trade-off is that when you sell, the IRS "recaptures" those deductions by taxing part of your gain at ordinary income rates rather than the lower capital gains rate.

Think of it as the government lending you a tax deduction today and collecting it back when you sell. The net result is not a penalty — it is a timing difference. But the timing matters a lot if you did not expect it.

Without a cost segregation study, the recapture calculation is straightforward: you subtract the total depreciation you have taken — or could have taken — from your gain, and that portion is taxed as ordinary income, capped at 25%. The rest of your gain qualifies for the lower long-term capital gains rate.

How a Cost Segregation Study Changes the Recapture Math

A cost segregation study reclassifies parts of your building from 39-year or 27.5-year property to shorter-lived asset classes: 5-year, 7-year, and 15-year. This lets you accelerate depreciation into the early years of ownership instead of spreading it evenly across decades. For a full walkthrough of how this works on commercial property, see our guide on cost segregation for commercial real estate.

That acceleration is the reason a study pays for itself so quickly. But it also means you have taken more depreciation by the time you sell.

Here is how the two paths compare on a $1.2 million commercial building:

Standard depreciation: roughly $30,000 per year for 39 years. After five years, total depreciation taken is about $150,000.

Cost segregation: front-loads a significant portion into years 1 through 5. After five years, total depreciation taken might be $330,000 or more, depending on the property's composition.

When you sell, the recapture calculation starts from the depreciation you actually took — or could have taken. The larger number means more of your gain gets recaptured. But the trade-off matters: you had the use of those tax savings for five years, and you had them early, when the building's income was lower and the deductions mattered most. Property owners who bought a building years ago and never commissioned a study can still run a look-back cost segregation study to claim missed depreciation.

Section 1250 Recapture: Ordinary Income vs. Capital Gains

This is where the tax code splits into two buckets.

Unrecaptured Section 1250 gain — the portion of your gain attributable to straight-line depreciation — is taxed at a maximum rate of 25%. That is higher than the 15% or 20% long-term capital gains rate most high earners pay, but it is lower than their ordinary income rate of 32% or 35%.

But cost segregation reclassifies some of that accelerated depreciation into Section 1245 property — personal property like carpeting, lighting, and specialty fixtures. When you sell, the gain attributable to that 5-year and 7-year property is recaptured as ordinary income at your full marginal rate, with no 25% cap.

For a California high earner paying 35% federal plus the 3.8% net investment income tax plus California's 9.3% or 13.3% rate, that portion of the gain could be taxed at a combined rate over 45%. This is one reason it matters whether your short-term rental is depreciating over 39 years or has a study done — the asset breakdown changes what rate applies at sale.

The Bonus Depreciation Factor: Timing Matters

Bonus depreciation (Section 168(k)) let you deduct 100% of the cost of qualified 5-year and 7-year assets immediately in the year they were placed in service. That provision has been phasing down since 2023: 80% in 2023, 60% in 2024, 40% in 2025, and 20% in 2026.

If you did a cost segregation study in 2022 or 2023 and claimed 100% bonus depreciation, you took a very large deduction those years. The trade-off: the full amount is subject to ordinary income recapture when you sell. If you place property in service in 2026, only 20% bonus applies, and the recapture exposure is proportionally lower.

This is why the timing conversation matters. A property placed in service in 2022 with maximum bonus depreciation and sold in 2026 will produce a larger recapture bill than one placed in service this year, where the bonus is smaller to begin with. The question "is cost segregation worth it in 2026" depends partly on when you placed the property in service and when you expect to sell.

Planning Around Recapture: 1031 Exchanges and Timing Strategies

The most direct way to defer depreciation recapture is a 1031 exchange. By rolling the proceeds from the sale into a like-kind replacement property, you defer both the capital gains tax and the depreciation recapture. Your accumulated depreciation carries over to the new property, and the recapture clock starts over.

For an investor who wants to continue owning real estate rather than cash out, a 1031 exchange solves the recapture problem without any tax cost. The recapture is not forgiven — it is deferred until the replacement property is sold outside of an exchange. If you have a larger capital gain and want to explore alternatives, opportunity zone investing offers another deferral path worth comparing.

Another option is to hold the property long enough that the time value of the early deductions compensates for the eventual recapture. The math generally favors the cost segregation study even with full recapture, because you had years of use of the money. But the calculation changes if you sell very soon after placing the property in service — recapture with minimal time benefit can produce a net negative outcome.

For California owners, state treatment adds another layer. California did not fully conform to federal bonus depreciation in several years and has its own rules around depreciation recapture. The interaction between federal and state treatment means the total combined rate on recaptured income can be significantly higher than what a federal-only analysis suggests.

Know the Full Picture Before You Sell

Depreciation recapture after a cost segregation study is not a reason to skip the study. For most property owners, the time value of the early deductions outweighs the eventual recapture. But it is a reason to plan ahead — to know what the tax bill will look like before you list the property, and to decide whether a 1031 exchange or a holding period adjustment makes sense for your situation.

FAQ

What is depreciation recapture on real estate?

Depreciation recapture is an IRS rule that taxes the gain from depreciation you previously claimed when you sell a property. The recaptured amount is taxed at ordinary income rates or a capped 25% unrecaptured gain rate, rather than the lower capital gains rate.

Does a cost segregation study increase depreciation recapture?

Yes. By accelerating depreciation into the early years of ownership, a cost segregation study increases the total depreciation taken by the time you sell. This means more of your gain is subject to recapture, though you had years of use of the tax savings in between.

What is the difference between Section 1245 and Section 1245 recapture?

Section 1250 recapture applies to real property depreciated on a straight-line basis and is capped at 25%. Section 1245 recapture applies to personal property like fixtures and equipment and is taxed at your full ordinary income rate. Cost segregation creates more Section 1245 property, exposing that portion to the higher rate.

Can a 1031 exchange avoid depreciation recapture?

A 1031 exchange defers both capital gains tax and depreciation recapture. The accumulated depreciation carries over to the replacement property. Recapture is deferred until that replacement property is eventually sold outside of an exchange.

How does bonus depreciation phaseout affect recapture in 2026?

Bonus depreciation drops to 20% in 2026, down from 100% in 2022. If you claimed 100% bonus on assets in 2022 or 2023 and sell in 2026, the full amount is subject to ordinary income recapture. Property placed in service in 2026 has proportionally lower recapture exposure.

What happens to depreciation recapture when the owner dies?

When a property owner dies, heirs receive a step-up in basis to the fair market value at death. This effectively eliminates both the built-in capital gain and the accumulated depreciation recapture, giving the new owner a fresh depreciation schedule.
