Section 1245 vs. Section 1250 Property in Cost Segregation

The two categories

All depreciable assets fall into one of two IRS categories. Section 1250 property is real property — the building structure, its structural components, and land improvements. Depreciation recapture on Section 1250 property is the more favorable kind: it's taxed at your ordinary rate but capped at a maximum of 25% (unrecaptured Section 1250 gain).

Section 1245 property is personal property and certain other assets — equipment, appliances, machinery, and many building components when reclassified by a cost segregation study. Recapture on Section 1245 property is less favorable: it's taxed as ordinary income at your marginal rate, which could be 32%, 35%, or 37% for higher earners.

What cost segregation does

A cost segregation study identifies building components that qualify as Section 1245 property even though they are physically attached to a building. Examples include specialty electrical for a particular tenant's use, process piping, certain flooring, cabinets, and other elements tied to a specific use rather than general occupancy.

By reclassifying these to 5- or 7-year property, they depreciate faster — but they also become Section 1245 property. That means when you sell, those components' depreciation recaptures at ordinary income rates rather than the 25% cap. For a high-income investor in the 37% bracket, this could mean recapturing an accelerated deduction at a higher rate than it was taken — a real cost if not planned for.

Planning around the recapture difference

The standard answer is the 1031 exchange: defer both the Section 1245 and Section 1250 recapture by rolling the property. Alternatively, if you plan to hold until death, the step-up in basis your heirs receive eliminates accumulated recapture for both asset types — making cost segregation + hold-until-death a powerful strategy for long-term real estate investors. If you plan to sell, model both recapture amounts before commissioning the study to ensure the accelerated deductions today outweigh the higher recapture cost at sale.

How each type is actually recaptured on sale

The two categories are recaptured by different mechanics. Section 1245 recapture under IRC § 1245(a) is the lesser of (a) all depreciation and amortization you claimed on the asset or (b) your gain on that asset (amount realized minus adjusted basis). That amount is taxed as ordinary income at your marginal rate, figured in Part III of Form 4797 and carried to Part II. Any gain beyond the depreciation you took is Section 1231 gain, generally treated as long-term capital gain.

Section 1250 recapture works differently and is milder for modern real estate. True 1250 recapture applies only to additional depreciation — depreciation claimed in excess of straight-line. Because buildings placed in service after 1986 must use straight-line MACRS (27.5 years residential, 39 years commercial), most have zero additional depreciation and therefore zero true 1250 recapture. Instead, the depreciation you claimed becomes unrecaptured Section 1250 gain, which is technically a capital gain taxed at a maximum rate of 25%, computed on the Unrecaptured Section 1250 Gain Worksheet in the Schedule D instructions. So a cost segregation study does not change the building shell's treatment — it carves out components and re-labels their future recapture as ordinary 1245 recapture.

A worked example: the two rates side by side

Suppose you buy a commercial building for $1,000,000, allocate $200,000 to land, and a cost segregation study reclassifies $150,000 of the $800,000 depreciable basis into 5- and 15-year property, leaving $650,000 as 39-year Section 1250 real property. With 100% bonus depreciation you deduct the full $150,000 of 1245 components in year one and depreciate the $650,000 shell straight-line. Years later you sell at a gain.

At sale, the $150,000 of accelerated deductions on the 1245 components is recaptured as ordinary income (to the extent of gain on those components). For a 37%-bracket seller, that slice is taxed at 37% rather than the 25% cap — roughly $18,000 more tax on that $150,000 than if it had stayed 1250 property. Meanwhile the depreciation on the $650,000 shell is unrecaptured Section 1250 gain taxed at up to 25%. The character split is the whole point of understanding 1245 versus 1250: the same depreciation dollar can come back at 25% or at 37% depending on which bucket it sat in.

Land improvements: 1250 property despite the short life

A common trap is assuming every shorter-life component a study carves out is Section 1245. Land improvements — parking lots, sidewalks, curbing, fencing, landscaping, and site utilities — are 15-year property, yet they are classified as Section 1250 real property, not 1245. That normally means the favorable 25% recapture treatment. But there is a wrinkle: 15-year land improvements are depreciated using the 150% declining-balance method by default (and can carry bonus depreciation), both of which produce depreciation in excess of straight-line. That excess is genuine additional depreciation subject to true ordinary-income Section 1250 recapture on sale — one of the few places a modern investor actually encounters ordinary 1250 recapture. A good study report should flag land improvements separately so the character of the eventual gain is not a surprise.

Why the character change is usually still worth it

Even though 1245 recapture comes back at ordinary rates, cost segregation typically still wins on a present-value basis. You deducted the accelerated amount up front — often at the same ordinary rate — and kept the tax savings working for years before any recapture is due. Recapture is also capped at the lesser of depreciation or gain, so if the components have genuinely declined in value you may recapture less than you deducted. And two exits remove recapture entirely: a 1031 exchange defers both the 1245 and 1250 recapture into replacement property, and holding until death gives heirs a step-up in basis that erases all accumulated recapture. The character change is a reason to plan the exit, not a reason to skip the study.

The Section 1231 netting and Form 4797 flow

Sales of depreciable business real estate run through Form 4797, and the interaction with Section 1231 matters. After recapture is carved out (1245 ordinary in Part III to Part II; 1250 additional depreciation, if any, likewise ordinary), the remaining gain is Section 1231 gain that nets against Section 1231 losses for the year. A net 1231 gain is generally treated as long-term capital gain (with the unrecaptured 1250 slice taxed at up to 25%), while a net 1231 loss is fully ordinary and not subject to the $3,000 capital-loss limit. Watch the five-year nonrecaptured 1231 loss lookback: if you deducted ordinary 1231 losses in the prior five years, an equal amount of this year's 1231 gain is recharacterized as ordinary income. Clean records by asset class are what let your preparer route each slice correctly.

Reading your cost segregation report through the recapture lens

When you receive the study, do not just look at the total reclassified into shorter lives — read the asset schedule for its recapture character. Components moved to 5- or 7-year MACRS lives (carpet, cabinetry, decorative lighting, dedicated electrical, appliances) are Section 1245 and will recapture at ordinary rates. Components moved to a 15-year life are usually land improvements — Section 1250, but potentially carrying additional depreciation from 150% declining balance or bonus. The 39- or 27.5-year shell stays 1250 with only unrecaptured 1250 gain. Ask the engineer to tag each line with its Code section and, ideally, to preserve original component costs so that at sale you can compute recapture on each asset separately rather than defaulting to a blunt, unfavorable split. A well-organized report is as valuable at the exit as it is in the acquisition year.

Common misconceptions

Three misconceptions recur. First, that cost segregation 'creates' recapture — it does not; the depreciation would be recaptured either way, the study only changes some of it from 25%-capped to ordinary. Second, that all recapture is taxed at 25% — only the unrecaptured Section 1250 gain on real property is capped at 25%; Section 1245 recapture has no cap and rises with your bracket. Third, that recapture is taxed even on a loss — recapture applies only to gain, and Section 1245 recapture is limited to the lesser of depreciation or gain, so a component sold at a genuine loss triggers no recapture on that piece. Getting these straight lets you weigh the up-front deduction against the true, often smaller, recapture cost at sale.

Frequently asked questions

What is the recapture rate on Section 1245 property from cost segregation?

Ordinary income rates — up to 37% for the highest bracket — not the 25% cap that applies to Section 1250 real property recapture.

How do I know which components are Section 1245 vs. 1250?

The cost segregation study report lists each component and its classification. Items reclassified to 5- or 7-year MACRS life are typically Section 1245; 15-year land improvements are Section 1250.

Does a 1031 exchange defer Section 1245 recapture?

Yes — a 1031 exchange defers all gain including Section 1245 recapture. The carried-over basis keeps the recapture potential alive in the replacement property.

Is unrecaptured Section 1250 gain the same as ordinary income?

No. Unrecaptured Section 1250 gain is a category of long-term capital gain taxed at a maximum rate of 25% — it is not ordinary income. True Section 1250 recapture (ordinary income) applies only to depreciation taken in excess of straight-line, which is rare for buildings but can occur on 15-year land improvements. Section 1245 recapture, by contrast, is always ordinary income.

Does cost segregation always increase my recapture tax?

It changes the character of some recapture from 25%-capped to ordinary, which can increase the rate on that slice for high earners. But the up-front deduction usually outweighs it on a present-value basis, and a 1031 exchange or a step-up in basis at death can eliminate the recapture entirely. Model your planned exit before assuming the recapture is a net cost.

How is Section 1245 recapture calculated?

It equals the lesser of the total depreciation and amortization you claimed on the asset or your gain on that asset (amount realized minus adjusted basis). That amount is ordinary income; any additional gain is Section 1231 gain, generally long-term capital gain. It is figured in Part III of Form 4797.
