You bought a delivery van three years ago, wrote off the entire cost in year one using bonus depreciation, and have been quietly enjoying the tax savings ever since. Now the van is worth $18,000 on the used market and you're ready to trade up. Congratulations — you're about to owe ordinary income tax on every dollar of that sale, even though the van itself never appreciated.
This is depreciation recapture, and it catches more small business owners off guard than almost any other provision in the tax code. It's not a penalty. It's not a loophole closing. It's the IRS collecting on a deduction you already took, the moment you sell the asset for more than its adjusted basis. If you don't see it coming, it can turn what feels like a routine equipment upgrade or property sale into a tax bill that eats your entire profit margin.
The Basic Mechanics: Depreciation Is a Loan, Not a Gift
Every dollar of depreciation you deduct lowers your asset's "adjusted basis" — essentially, its value on your books for tax purposes. Depreciate a $50,000 piece of equipment down to $0, and your adjusted basis is zero, no matter what the asset is actually worth.
Here's the part that surprises people: when you sell that asset, the IRS doesn't let you treat the entire sale price as a capital gain taxed at favorable long-term rates. Instead, it recaptures the depreciation you deducted and taxes that portion at your ordinary income rate — up to 37% in 2026 — because that's the rate you would have paid if you'd never gotten the deduction in the first place.
Depreciation recapture only applies when you sell at a gain. Sell for less than your adjusted basis, and there's nothing to recapture — you likely have a deductible loss instead. But if the equipment or property still has real market value after you've depreciated it to near zero on paper, that gap between adjusted basis and sale price is exactly what recapture targets.
Section 1245 vs. Section 1250: Two Very Different Rules
The recapture rules split based on what kind of asset you're selling.
Section 1245 property covers tangible personal property used in a business — machinery, vehicles, computers, furniture, manufacturing equipment. When you sell Section 1245 property at a gain, all of the depreciation you claimed gets recaptured as ordinary income, up to the total gain on the sale. There's no partial treatment here: if you fully depreciated a $40,000 forklift and sell it for $12,000, that entire $12,000 gain is ordinary income, reported on Form 4797, Part III.
Section 1250 property covers real property — rental buildings, warehouses, commercial real estate, and other structures. Real estate recapture is gentler because most real property is depreciated using the straight-line method, and Congress capped the recapture rate rather than taxing it at full ordinary rates. Instead, the depreciation portion of your gain is taxed as "unrecaptured Section 1250 gain," capped at a maximum 25% federal rate, while the remaining appreciation above your original purchase price gets standard long-term capital gains treatment (0%, 15%, or 20% depending on income).
A worked example: Say you bought a commercial building for $390,000, claimed $100,000 in depreciation over the years, and sold it for $500,000. Your adjusted basis is $290,000, so your total gain is $210,000. Of that, $100,000 (the depreciation you claimed) is taxed at up to 25%. The remaining $110,000 — the actual appreciation above your original cost — gets ordinary long-term capital gains rates. Two different tax rates, on two different slices of the same sale.
Section 179 and Bonus Depreciation Made This Sneakier
The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for qualifying property placed in service after January 19, 2025, and pushed the Section 179 expensing limit to $2,560,000 for 2026. That means a business can now write off the entire cost of a $200,000 piece of equipment in the year it's purchased — no multi-year depreciation schedule required.
That's a genuine cash-flow win, but it front-loads the recapture exposure too. An asset expensed immediately under Section 179 or bonus depreciation has an adjusted basis of $0 from day one. Sell it — or even stop using it for business — anytime after that, and essentially the entire sale price (or fair market value, in some cases) becomes ordinary income exposure.
There's a second trap specific to Section 179: if your business use of the asset drops to 50% or less in any year during its recovery period, you have to recapture part of the deduction as ordinary income that year, even without selling anything. This shows up constantly with vehicles — a truck bought at 80% business use that ends up running mostly personal errands a couple years later can trigger recapture on the difference between what you deducted under Section 179 and what straight-line depreciation would have allowed. Track business-use percentage the way you'd track mileage for a deduction, because it works both directions.
Real Estate Owners: Don't Forget Depreciation Even If You "Didn't Use It"
One version of this surprises real estate investors more than anyone: recapture applies to depreciation you were entitled to claim, whether or not you actually claimed it on your return. If you owned a rental property for a decade and forgot to depreciate it (or your preparer didn't), the IRS still treats you as if you took the deduction when you calculate recapture at sale. The fix, if you're in that position, is a Form 3115 change of accounting method to claim the missed depreciation retroactively — not simply ignoring it and hoping the recapture math skips you. Talk to a CPA before you list the property, not after you've signed a purchase agreement.
How Business Owners Actually Manage This
Depreciation recapture isn't avoidable if you sell an appreciated, depreciated asset for cash — but it is manageable with planning:
- 1031 like-kind exchanges (real property only, post-2017 tax law) let you defer both the capital gain and the recapture by rolling proceeds into a replacement property of equal or greater value, with equal or greater debt replacement. This defers the tax bill rather than eliminating it — your lower basis carries into the new property.
- Installment sales spread the gain (and the associated tax) over the years you actually receive payment, which can keep you out of a higher bracket in the sale year — though depreciation recapture on Section 1245 property is generally required to be reported in the year of sale even under an installment method, so this strategy helps more with Section 1250 gains.
- Timing the sale to a lower-income year reduces the rate on the ordinary-income portion of the recapture, since that portion still moves with your marginal bracket.
- Cost segregation studies, ironically, accelerate depreciation on real property components — useful for current-year tax savings, but they increase future recapture exposure, so they're a trade of a smaller, later problem for a bigger, sooner benefit. Model both sides before committing.
- Stepped-up basis at death is the one clean way recapture disappears entirely: heirs who inherit depreciated property receive a basis reset to fair market value, wiping out the recapture liability that would have applied to a lifetime sale. This is a core reason estate planning and business succession planning intersect with equipment and real estate strategy.
Why This Belongs in Your Books, Not Just Your Tax Return
Depreciation recapture is a tax-return-time surprise almost entirely because it's a bookkeeping blind spot the rest of the year. If your accounting system tracks an asset's original cost but not its running adjusted basis, you have no way to estimate the tax hit before you agree to a sale price — you find out in April, after the deal already closed.
This is where keeping clean, itemized records of every asset's basis, depreciation method, and accumulated depreciation actually pays off, not just as bookkeeping hygiene but as a decision-making tool. Beancount.io provides plain-text accounting that keeps every asset's cost basis and depreciation history transparent and queryable — version-controlled, auditable, and easy to hand to your CPA before a sale, not after.
