Are Land Improvements 1245 or 1250 Property?

Land improvements are Section 1250 property by default. The tax code treats them as depreciable real property attached to the land, so fences, parking lots, sidewalks, drainage systems, and similar site work sit in the Section 1250 category unless something specific pulls them into Section 1245. Whether land improvements are 1245 or 1250 property matters most at sale: Section 1245 recapture taxes all prior depreciation as ordinary income at rates up to 37%, while Section 1250 caps most of the recapture tax at 25%. Three narrow situations convert a land improvement from 1250 to 1245, and one widely assumed trigger — claiming bonus depreciation — does not.

Why Section 1250 Is the Default

Section 1250 property is defined in the Internal Revenue Code as any depreciable real property that is not Section 1245 property.¹ That residual definition is the whole game. Property doesn’t have to affirmatively qualify as Section 1250. It lands there unless something specific pulls it into Section 1245.

Paved lots, perimeter fencing, retaining walls, sidewalks, drainage, and landscaping are all real property affixed to the land. They are depreciable, and under the Modified Accelerated Cost Recovery System they fall into a 15-year recovery class.² None of that pushes them out of Section 1250. Buildings and their structural components sit in the same statutory bucket, which is why commercial and residential rental structures are also Section 1250 property even though their recovery periods are longer.

One depreciation detail changes the recapture math later: 15-year land improvements do not use straight-line under the General Depreciation System. They use the 150% declining-balance method, switching to straight-line when that produces a larger deduction. The gap between accelerated depreciation and what straight-line would have allowed becomes a small slice of ordinary income at sale, which is covered below.

The Three Ways a Land Improvement Becomes Section 1245 Property

A land improvement shifts out of Section 1250 only through one of three statutory routes. Each is narrow, and misapplying any of them produces the wrong tax result.

Integral Part of Manufacturing, Production, or Specified Services

Under Section 1245(a)(3)(B), tangible property that is not a building or structural component qualifies as Section 1245 property if it was used as an integral part of manufacturing, production, extraction, or in furnishing transportation, communications, electrical energy, gas, water, or sewage disposal services.³ A specialized concrete pad built solely to support heavy manufacturing equipment, or a private road used exclusively to transport extracted materials from a mine, can qualify under this exception.

The IRS Cost Segregation Audit Technique Guide confirms that land improvements like sidewalks, roads, sewers, and fences can land on either side of the 1245/1250 line depending on their function, and the guide notes there are no bright-line tests.⁴ Examiners look at how the improvement is attached, whether it can be moved, what it was designed to do, and the taxpayer’s intent when installing it.

Section 179 Expensing

Section 1245(a)(3)(C) explicitly converts real property into Section 1245 property when the taxpayer’s adjusted basis reflects amortization under certain code sections, including Section 179.³ If you expense a land improvement under Section 179, the expensed portion becomes Section 1245 property. Sell the asset at a gain later, and every dollar of that prior Section 179 deduction is recaptured as ordinary income.

The policy logic is straightforward. Section 179 gives an immediate, full write-off against ordinary income, so the recapture rule prevents taxpayers from taking an ordinary deduction on the front end and claiming favorable capital gains rates on the back end. For 2026, the maximum Section 179 deduction is $2,560,000 with a phase-out beginning at $4,090,000 in total equipment purchases.

Reclassification Through a Cost Segregation Study

A cost segregation study breaks a property into its component parts and reassigns pieces to shorter MACRS lives. During that process, certain pieces of what looks like a land improvement may be reclassified as tangible personal property. A site lighting system might become 7-year personal property, or specialized paving at a manufacturing plant might qualify under the integral-part-of-manufacturing test.

The IRS evaluates these reclassifications using factors from the Whiteco case, including whether the property is capable of being moved, whether it was designed to remain permanently in place, how substantial the removal job would be, and how much damage removal would cause.⁴ Movability alone isn’t determinative. A bolted-down structure can still be personal property if the other factors support it. Aggressive cost segregation without a defensible engineering report is a common audit target.

Bonus Depreciation Does Not Change the Classification

This is the single most misunderstood point in land improvement taxation. Claiming bonus depreciation on a land improvement does not convert it from Section 1250 to Section 1245 property. Section 168(k), which governs bonus depreciation, is not listed among the code sections in Section 1245(a)(3)(C) that trigger reclassification.³ A 15-year land improvement that receives 100% bonus depreciation stays Section 1250 property.

The One Big Beautiful Bill, signed into law in 2025, restored permanent 100% bonus depreciation for qualified property acquired after January 19, 2025.⁵ Land improvements with a 15-year recovery period are eligible, so the full cost of a new parking lot or fence can be deducted in the year it is placed in service.

The trap is assuming that a full first-year write-off means full ordinary income recapture at sale. A taxpayer takes 100% bonus on a parking lot, treats it mentally like Section 179 expensing, and expects the entire gain to come back as ordinary income later. That isn’t what happens. The parking lot is still Section 1250 property, and the recapture follows Section 1250 rules. Section 179 and Section 168(k) look economically identical on the front end and produce materially different tax outcomes on the back end.

What the Classification Costs You at Sale

The 1245-versus-1250 split determines how much of the gain is taxed as ordinary income and how much receives capital gains treatment. The spread on the same dollar of gain can easily reach 12 percentage points or more.

Section 1245 Recapture

For any land improvement classified as Section 1245 property, every dollar of depreciation previously claimed is recaptured as ordinary income up to the amount of gain realized.³ Ordinary income rates apply, reaching 37% at the top 2026 federal bracket. If a specialized foundation expensed for $80,000 under Section 179 is later sold for $80,000, the entire proceeds are ordinary income. No part of the gain up to the depreciation amount gets capital gains treatment.

Section 1250 Recapture

Section 1250 recapture works in two layers, and the 150% declining-balance method used for 15-year land improvements makes both layers relevant.

The first layer is ordinary income recapture on “additional depreciation,” which is the amount by which actual depreciation exceeds what straight-line depreciation would have been.¹ Because 15-year land improvements use 150% declining balance, there is a gap between the accelerated figure and straight-line in the early years. That gap comes back as ordinary income.

The second layer covers the depreciation that would have been claimed under straight-line. This portion is taxed as unrecaptured Section 1250 gain at a maximum federal rate of 25%, higher than the standard 15% or 20% long-term capital gains rates but well below the top ordinary income rate. Any gain above total depreciation is taxed at regular long-term capital gains rates.

Buildings depreciated straight-line (39-year commercial, 27.5-year residential) have no additional depreciation layer because there is no gap to recapture. Land improvements are different precisely because they use an accelerated method.

The Net Investment Income Tax

Both Section 1245 and Section 1250 recapture gains can trigger the 3.8% net investment income tax for taxpayers with modified adjusted gross income above $200,000 (single) or $250,000 (married filing jointly). The surtax sits on top of the rates above, pushing the effective maximum on Section 1245 recapture to 40.8% and on unrecaptured Section 1250 gain to 28.8%.

Losses Follow a Different Path

Everything above addresses gains. Losses on land improvements used in a trade or business are Section 1231 property, which means losses are treated as ordinary losses fully deductible against other income. That beats capital loss treatment, which caps deductions at $3,000 per year with the excess carried forward.

There is a catch under the five-year lookback rule in Section 1231(c). If you claimed net Section 1231 losses in any of the five preceding tax years, current-year Section 1231 gains are recharacterized as ordinary income until those prior losses are fully recaptured. The rule stops taxpayers from alternating between ordinary loss deductions in bad years and capital gains treatment in good years.

Reporting the Sale

The sale of a land improvement goes on Form 4797 (Sales of Business Property). Part III calculates the ordinary income recapture, under either Section 1245 or Section 1250 rules. Gain exceeding the recapture amount flows to Form 8949 and Schedule D for capital gains treatment.⁶ Depreciation claimed during the asset’s life is reported on Form 4562.⁷

If a cost segregation study split components of the same physical improvement between Section 1245 and Section 1250, each component needs its own line on Form 4797 with its own recapture calculation. Keep the engineering report and the supporting documentation. Combining split components into a single entry almost always produces the wrong number, either overpaying through unnecessary ordinary income recapture or underpaying and inviting an adjustment on audit.
