Section 1245 vs 1250 Property: What Changes When You Sell

Section 1245 and Section 1250 are the two Internal Revenue Code labels that decide how depreciation comes back to you when you sell business or rental property. If a cost segregation study has split your building into shorter-life components, the label on each component shapes how much of your future gain is taxed as ordinary income.

As co-founder of Seneca Cost Segregation and a real estate investor myself, I’ve had this conversation from both sides of the table. When one of our studies reaches a client’s CPA, the follow-up we hear most often is about the exit: which of these components will be taxed at ordinary rates when the property sells, and which will not?

Below, I define both classes, show where the IRS draws the line inside a building, and explain how recapture works under each so you can plan the sale early.

What Section 1245 and Section 1250 Property Mean

Both terms come from the recapture rules Congress enacted in 1962, and both describe property you depreciate.

Section 1245 Property in a Real Estate Context

Section 1245(a)(3) covers personal property plus a handful of tangible assets that are not buildings. For a property owner, that usually means what a cost segregation study pulls out of the building: appliances, carpeting, furniture, and other components the engineering shows are not structural.

The statute also reaches several kinds of property beyond ordinary personal property:

• ●Non-building tangible property used as an integral part of manufacturing, production, extraction, or utility services
• ●Single-purpose agricultural or horticultural structures and petroleum storage facilities
• ●Any portion of real property expensed under Section 179
• ●Qualified production property, added to the list by the One Big Beautiful Bill

Section 1250 Property and the Buildings It Covers

Section 1250(c) defines its class by subtraction: depreciable real property that is not Section 1245 property. IRS Publication 544 adds that it must never have been 1245 property, so a conversion from 1250 to 1245 is permanent.

In practice, the 1250 class holds the 27.5- or 39-year building and structural components such as walls, floors, windows, doors, and central air conditioning. Most land improvements sit here too, while land itself is not depreciable, as our explainer on what counts as real property describes.

Section 1245 vs 1250 Side by Side

Here is how the two classes compare on the points a real estate owner feels.

How the IRS Separates 1245 From 1250 Property

The line between the classes runs through most buildings, and the IRS audit guide says there is no bright-line test.

According to the IRS Cost Segregation Audit Techniques Guide, the core question is whether an asset is a building, an inherently permanent structure, or a structural component of one. Courts answer that with the Whiteco Industries test, which weighs factors such as:

• ●Whether the property can be moved, and was designed to stay in place
• ●How difficult removal would be, and how much damage it would cause
• ●How the property is attached to the land or building

In Hospital Corporation of America (1997), the Tax Court held that the former investment tax credit tests still decide what counts as 1245 property under MACRS, and the IRS acquiesced on that point.

What we find on commercial walkthroughs is that one building system can sit in both classes. The guide’s own example splits an electrical distribution system, treating the share feeding specialized equipment as 1245 property, and our summary of the IRS audit techniques guide covers how examiners test that allocation.

Where Each Cost Segregation Component Lands

A study sorts a property into recovery classes, and each class carries a predictable, though not automatic, 1245 or 1250 label.

Five- and Seven-Year Personal Property

These components are Section 1245 property, and every dollar of bonus claimed on them is potential ordinary income, up to the gain allocated to them at sale. Our walkthrough of how tangible personal property is identified shows the documentation behind each item.

Fifteen-Year Land Improvements

Paving, sidewalks, fencing, and landscaping are 15-year property, and the audit guide notes that land improvements can fall in either class. Under the credit-era regulation it cites, paved parking areas and fences are not tangible personal property, so most site work is Section 1250 property that still qualifies for bonus, a combination covered below.

Qualified Improvement Property

QIP is an interior improvement to a nonresidential building made after the building was first placed in service, and the Treasury regulations treat it as Section 1250 property. With a 15-year life and bonus eligibility, as our guide to leasehold improvements and bonus depreciation explains, QIP sits in the same position as site work at sale.

The Building and Its Structural Components

Whatever remains is the 27.5- or 39-year building on straight-line depreciation, which produces no additional depreciation once held more than a year, so it returns as unrecaptured Section 1250 gain. Our breakdown of building component reclassification shows which parts typically move out.

How Recapture Works Under Each Section

Both sections convert part of a gain from capital to ordinary treatment, and they measure that part differently.

Section 1245 Recapture as Ordinary Income

Under Section 1245, the ordinary income portion is the lower of recomputed basis or the amount realized, minus adjusted basis. Recomputed basis adds back all depreciation and amortization, including Section 179.

In plain terms, if a component sells for at least what you paid, every dollar of depreciation on it is ordinary income. Gain above that is Section 1231 gain.

Section 1250 Additional Depreciation

Section 1250 recaptures only additional depreciation, meaning depreciation in excess of what the straight-line method would have produced. If you hold the property one year or less, all of the depreciation counts as additional depreciation.

For nonresidential and residential rental property, the applicable percentage is 100%, so all additional depreciation, limited to the gain, is ordinary income.

Unrecaptured Section 1250 Gain

The remaining depreciation on 1250 property escapes ordinary recapture and receives its own rate. IRS Topic 409 confirms that unrecaptured Section 1250 gain is taxed at a maximum 25% rate, and Publication 544 limits it to your net Section 1231 gain for the year.

Our article on the depreciation recapture tax rate shows how that ceiling fits the rest of a sale.

How Bonus Depreciation Changes the Section 1250 Math

Bonus depreciation is where most summaries of the two sections go wrong.

Under Treasury Regulation section 1.168(k)-2(g)(3), bonus counts as depreciation allowed for Section 1245, and for Section 1250 it is not a straight-line method.

The One Big Beautiful Bill restored 100% bonus for property acquired and placed in service after January 19, 2025, as our breakdown of the bonus depreciation changes in the Big Beautiful Bill covers. When that write-off lands on site work or QIP, the portion above straight line is additional depreciation recaptured as ordinary income, a gap that generally narrows the longer you hold.

Here is how gain can split on a hypothetical sale where each component sells for at least its cost and $300,000 of the gain traces to depreciation taken.

In a hypothetical 35% bracket, the $90,000 of 1245 recapture carries $31,500 of federal tax, while tax on the $150,000 of building depreciation is capped at $37,500. The site work row depends on the hold period, which is why the study’s component detail matters at sale.

Mistakes to Avoid With Section 1245 and 1250 Property

Each of these errors surfaces at sale, when it is hardest to fix.

• ●Treating every 15-year asset as 1245 property: most paving and fencing is 1250 property, so the model overstates capital gain. Map each component to its section first.
• ●Assuming unclaimed depreciation avoids recapture: Publication 544 measures recapture on depreciation allowed or allowable, so skipping it forfeits the deduction only. Catch it up through Form 3115 instead.
• ●Expecting a 1031 exchange to shelter all 1245 recapture: Section 1245(b)(4) caps recapture at gain recognized plus non-1245 property received, so a replacement with little personal property can create ordinary income with no cash. Plan the replacement property mix before you identify it.
• ●Counting on an installment sale to defer recapture: recapture is taxed in the year of sale even if no payment arrives. Set aside cash for it.
• ●Forgetting that Section 179 creates 1245 property: real property expensed under Section 179 becomes 1245 property, so the full deduction can return as ordinary income. Weigh that before expensing a roof.
• ●Ignoring the corporate add-on: a C corporation selling 1250 property treats an extra 20% of the gap between 1245-style and actual 1250 recapture as ordinary income. Build it into any entity-level sale.
• ●Letting the sale price allocation drift from the component split: Publication 544 allocates the amount realized by relative fair market value or an arm’s-length buyer and seller agreement. Settle it with your CPA, with the study’s asset detail on file.

Frequently Asked Questions

Below are the questions we hear most from investors and CPAs sorting components between the two sections.

How Seneca Supports Your Component Classification

Every 1245 or 1250 label must hold up at purchase and at sale. Seneca’s in-house engineers break the property down into every component it contains, from the shell to the site work, after an onsite inspection or a virtual tour, whichever suits the building. Our Head of Engineering then signs off on each study before your CPA sees it.

You deal directly with a dedicated Project Manager, our Engineering team, and an Advisor, with real-time updates as the study moves through each stage. Audit defense is included, and our record across 10,200+ properties assessed stands at zero IRS audits triggered or lost.

Cost segregation is the only work we do, and that includes Qualified Production Property (QPP) studies, which matter here because QPP now counts as Section 1245 property. To see what a study could classify on your property, start with our cost segregation calculator.

Conclusion

Section 1245 and Section 1250 rarely matter on the day you buy and matter a great deal on the day you sell. The 1245 label sends all of a component’s depreciation back as ordinary income, while 1250 limits ordinary recapture to the excess over straight line and caps the rest at 25%.

A study draws that line one component at a time, and bonus on site work and QIP moves part of the 1250 depreciation into the ordinary column. Model the exit with your CPA before you list, and ask us for a free estimate on your own property.
