§1250 Recapture Explained: The Hidden 25% Tax on Rental Property Sales

A client sold a long-term rental this spring. Ten-year hold. $245K gain. He had already done the math on the drive home: long-term capital gain rates, 20% tops, call it $50K to the IRS, move on.

Then his CPA walked him through the actual return. $36,250 of that gain was taxed at 25%. Not 20%. Not 23.8%. A flat 25%.

He didn’t lose a “loophole.” He met §1250.

The 1231 piece we just published walks the netting and the lookback. §1250 is the layer that runs inside the gain bucket before §1231 ever gets to deliver the punchline.

If you own real estate and you’ve taken depreciation, this section has your number, and it gets paid first.

What §1250 Actually Says and the Distinction

There are two different things going by the name “§1250,” and people mix them up constantly.

Recaptured §1250 gain. This is depreciation taken in excess of straight-line on real property, the accelerated portion only. For real property placed in service after 1986, MACRS forces straight-line on buildings. So, unless you’re sitting on a pre-1987 asset, recaptured §1250 is almost always zero.

The exception that does come up: anything you wrote off under bonus depreciation as §1250 property gets pulled back at ordinary rates. Rare on the building itself, but worth flagging if you’ve done aggressive bonus on building improvements.

Unrecaptured §1250 gain. This is the one that hits you. §1(h)(1)(E). The portion of your gain attributable to straight-line depreciation already taken is taxed at a maximum rate of 25%. You don’t need a cost seg, you don’t need an aggressive position, you don’t need anything except a building and a depreciation schedule.

The 25% rate finds you.

Plain-language version: if you took depreciation on the building, the gain up to the amount of depreciation you took comes back at 25%. The rest, the actual market appreciation, gets §1231 / LTCG treatment.

That’s the surprise. Real estate investors hear “long-term capital gain” and price the deal at 20%. The depreciation slice gets priced at 25%. The 5-point spread is your §1250 layer.

Why Real Property Gets a Different Rate than Equipment

If you’ve read the §1231 blog, you already know §1245 recapture (cost seg components, equipment, personal property) comes back at ordinary rates — 37% at the top. §1250 caps at 25%. That spread is not an accident.

Congress drew a line:

• §1245 property. Personal property and personal-property-type building components. Recapture is full ordinary income, up to all prior depreciation.
• §1250 property. Real property — the building itself. Recapture is limited to “additional” depreciation only (almost always zero post-1986), and the straight-line portion gets the 25% cap as unrecaptured §1250 gain.

The line matters because it drives the rate. Same dollar of depreciation taken. Two different rates on exit depending on which bucket it sits in. If the asset is a 5-year personal-property reclass from a cost seg, that depreciation comes back ordinary.

If it’s straight-line on the 27.5-year residential or 39-year commercial building, it caps at 25%.

This is also why “I did a cost seg” is not a free win on the back end. And needs more proper planning.

The Math Behind it All

Investor buys a single-family rental:

• Purchase price: $500,000 ($400,000 to building, $100,000 to land)
• Hold period: 10 years
• Straight-line depreciation taken: ~$145,000 ($400,000 ÷ 27.5 years × 10)
• Sale price: $600,000

Walk it:

• Adjusted basis: $500,000 − $145,000 = $355,000
• Total gain: $600,000 − $355,000 = $245,000

Now break the gain into rate buckets:

• Unrecaptured §1250 gain: $145,000 @ 25% = $36,250
• Remaining LTCG: $100,000 @ 20% + 3.8% NIIT = $23,800
• Total federal tax: ~$60,050

Compare to what the investor thought the bill was:

• If the whole $245,000 were taxed at 20%: $49,000
• The §1250 layer added ~$11,000 to a deal they had mentally priced at the LTCG headline rate

That’s a 22% overshoot on a number the investor “already knew.” This is the conversation that doesn’t happen until the return is in front of them, unless someone modeled it on the front end.

Cost Segregation Flips Part of the Recapture to Ordinary

This is the back-end cost most cost seg pitches don’t model.

A cost seg study reclassifies portions of the building, typically the 5, 7, and 15-year components, into §1245 property. That gives you accelerated deduction now (especially with 100% bonus back under OBBBA). On exit, those reclassified buckets do not get the 25% cap.

They come back at ordinary rates as §1245 recapture, up to the full amount of depreciation taken on those components.

The full lifecycle on the same property if you’d done a $100K cost seg reclass:

• $100K of depreciation runs through §1245 → ordinary on exit (~37% federal, ~40.8% with NIIT for active recapture) = roughly $40,800
• $45K of remaining straight-line depreciation → unrecaptured §1250 @ 25% = $11,250
• $100K of “real” appreciation → LTCG @ 23.8% = $23,800
• Total: ~$75,850 versus $60,050 without the cost seg

That’s not a reason to skip cost seg. It’s a reason to model the exit when you authorize the study. The acceleration is real, the time value of money is real, but so is the rate flip from 25% to 37%+ on the reclassified slice.

If you’re holding through death and getting a §1014 step-up, the recapture problem disappears. If you’re holding 5 years and selling outright, the recapture is the cost of the front-end deduction.

What CPAs miss: authorizing the cost seg without putting the exit model on paper. Investor sees the year-1 deduction, doesn’t see the exit-year recapture, and feels blindsided three years later. Run both sides of the trade in the engagement letter for the cost seg work.

§1250 Only Bites on Gains. What about Losses

Selling at a loss? §1250 doesn’t apply. There is no recapture on a loss sale.

Planning Moves: What to Actually Do with §1250

A tight list.

1. §1031 exchange. Defers the unrecaptured §1250 gain and the underlying §1231 gain alike. Not eliminated — deferred. Basis carries to the replacement property. Stack enough exchanges and run the property through death, and §1014 wipes the deferred recapture entirely. That’s the “swap till you drop” play. Legislative risk is real here — pay attention to whether step-up survives the next reconciliation cycle.
2. Installment sale under §453. Spreads the gain across the years payments are received. The catch most investors miss: unrecaptured §1250 gain is recognized first under §453’s ordering rules. You don’t get to spread the 25% layer proportionally with the LTCG layer. The §1250 piece hits in the early years. Run the cash flow math before you sign a seller-financed deal.
3. Hold strategy and §1014 step-up. If the plan is to die owning the property, the recapture problem dissolves at death. The heirs take a stepped-up basis equal to FMV, and all unrecaptured §1250 gain and §1245 recapture exposure go to zero. Worth a real conversation with estate planning if the investor is older or holding generationally.
4. Opportunity Zones. Unrecaptured §1250 gain qualifies as eligible gain for §1400Z-2 deferral. A 10-year QOZ hold pre-sunset gets the basis step-up to FMV on the QOZ investment. QOZ 2.0 language under OBBBA is moving — track it before you commit to a sponsor structure.
5. Time the sale across years. If you have a §1231 loss carryover or a §1231 loss currently triggering, pairing it against a §1250-heavy sale can absorb the LTCG slice — but not the 25% slice. The unrecaptured §1250 piece runs first and can’t be netted away by a §1231 loss. Worth modeling, not magic.
6. Allocate basis correctly at acquisition. Land vs. building allocation drives every dollar of depreciation you’ll ever take — and every dollar that comes back as §1250 on exit. Inflate land, and you take less depreciation. Inflate building and you take more, but the recapture is also larger. Either way, the IRS tests this number. Get the allocation supported by an appraisal or a defensible methodology at acquisition, not at sale.

Where People Blow It

The defense-layer version. Document each of these because the IRS tests every one:

• Assuming the whole gain on a rental sale is taxed at 20%
• Treating depreciation as optional (it’s not — “allowed or allowable” under §1250(b)(3), the IRS recaptures it whether you actually took it or not)
• Cost seg studies done without modeling the §1245 recapture on exit
• Weak land-vs-building allocations that don’t hold up under exam
• Forgetting the §1250 layer runs first in an installment sale
• Assuming §1031 eliminates §1250. It defers, it does not eliminate
• Confusing depreciation recapture with §1231 lookback recapture. They’re different mechanisms running at different layers

The most expensive one is the first. Investors model a sale at 20%, plan the next deal around the after-tax proceeds, and discover at filing that 25% ate $11K-$50K of the assumed wire. The deal they wanted to roll into doesn’t pencil.
