You bought a $60,000 work truck, deducted the entire cost in year one, and felt brilliant about it. Then you sell the truck three years later for $25,000 — and the IRS taxes every dollar of that sale as ordinary income. No capital gains rate, no discount for holding it for years. Your old deduction just turned into this year's tax bill.
That is depreciation recapture under Section 1245, and with 100% bonus depreciation back on the table, more small business owners are walking into it than at any point in the last decade. Here is how it works, when it bites, and how to plan around it.
What Section 1245 Recapture Actually Does
Section 1245 covers depreciable personal property: machinery, equipment, vehicles, computers, office furniture, and similar tangible business assets. The rule is short: when you sell Section 1245 property at a gain, the part of the gain equal to depreciation you already deducted is taxed as ordinary income.
The recapture amount is the lesser of two numbers:
- The gain you realized on the sale, or
- The total depreciation allowed or allowable on the asset, including Section 179 expensing and bonus depreciation.
Everything above that amount — gain beyond what you originally paid — can qualify for the lower capital gains treatment under Section 1231. But most used equipment sells for less than its purchase price, which means most sellers never see a dollar of capital gain. The entire profit is recapture.
A concrete example
You buy a CNC machine for $80,000 in 2026 and claim 100% bonus depreciation, writing off the full $80,000 against that year's income. Your adjusted basis is now zero.
In 2029 you sell the machine for $30,000. Your gain is $30,000 ($30,000 sale price minus $0 basis). Your depreciation taken was $80,000. Recapture is the lesser of the two: $30,000. The whole sale is ordinary income, taxed at your marginal rate — potentially 37% at the top federal bracket, plus state tax.
If instead the machine sold for $95,000 — more than you paid — the first $80,000 of gain would still be ordinary income, and only the remaining $15,000 would get capital treatment.
Why Bonus Depreciation Makes Recapture Bigger
Under normal MACRS depreciation, you spread deductions over 5 or 7 years, and an asset sold mid-life has only partial depreciation to recapture. Bonus depreciation compresses the entire deduction into year one, which also maximizes the recapture exposure from day one.
With 100% bonus depreciation permanently restored for qualifying property acquired after January 19, 2025, the pattern looks like this:
- Year of purchase: deduct the full cost, adjusted basis drops to zero.
- Any later sale: every dollar of sale proceeds up to the original cost is ordinary income.
This is not a reason to skip bonus depreciation — a deduction today is worth more than the same deduction spread over years, and rates or income may be lower in the sale year. But it is a reason to stop thinking of the write-off as free money. Part of its value is a loan from your future self, repayable on sale.
Section 179 Has Its Own Extra Tripwire
Section 179 expensing follows the same Section 1245 recapture on sale, with one additional trigger: if the business use of the asset drops to 50% or less during its recovery period, you must recapture part of the deduction even without selling anything.
The recapture equals the difference between what you deducted and what straight-line depreciation would have allowed. Common triggers include converting a business vehicle to mostly personal driving, or a spouse or employee starting to use listed property personally. Track business-use percentages annually on any Section 179 asset, especially vehicles.
Five Situations That Surprise Sellers
1. Selling at a "loss" that is actually a taxable gain
You paid $50,000 for equipment, fully depreciated it, and sell it for $20,000. It feels like a $30,000 loss. For tax purposes it is a $20,000 gain — sale price minus zero basis — and all of it is ordinary income. Manage your expectations before you list used equipment, and price the tax cost into your minimum acceptable offer.
2. Trading in or selling a business vehicle
Vehicles are Section 1245 property, and trade-in allowances count as sale proceeds. If you took heavy first-year deductions on a work truck or SUV, the trade-in value is largely ordinary income. This surprises owners who think of a trade-in as a swap rather than a sale.
3. Installment sales do not defer recapture
If you sell equipment on an installment plan, the installment method lets you spread most of the gain over the payment years — but depreciation recapture must be reported in the year of sale, even if you have not collected the cash yet. You can owe tax on money still sitting in the buyer's pocket.
4. Like-kind exchanges no longer help equipment
Since the Tax Cuts and Jobs Act, Section 1031 exchanges apply only to real property. You cannot roll equipment gains into replacement equipment tax-free the way previous generations of business owners could. When equipment sells, recapture is due.
5. Gifts and conversions have their own rules
Giving depreciated equipment to a family member or converting it to personal use can trigger recapture or shift the tax arithmetic in ways that produce phantom income. Get advice before moving a fully depreciated asset out of the business rather than selling it.
How Recapture Is Reported
The sale of business equipment goes on Form 4797, Sales of Business Property — not Schedule D. Depreciation recapture is computed in Part III and flows to your return as ordinary income. Any remaining Section 1231 gain above the recapture amount moves toward capital treatment.
What you need at filing time:
- Original purchase price and placed-in-service date.
- Total depreciation claimed each year, including Section 179 and bonus amounts from Form 4562.
- Sale price, sale date, and any selling expenses.
If your depreciation schedules live in a shoebox or a spreadsheet nobody has opened since 2023, reconstructing this at sale time is painful. Keep a fixed-asset register — one row per asset with cost, method, deductions taken, and adjusted basis — updated every year. It is the single cheapest insurance against a recapture surprise.
Planning Moves That Soften the Bill
Time the sale into a low-income year. Recapture is taxed at your marginal ordinary rate, so selling equipment in a year with lower overall income — a slow year, a sabbatical, early retirement — directly cuts the rate applied.
Sell before you fully depreciate, or hold past usefulness — run both numbers. There is no universal answer; model the after-tax proceeds of selling now versus later given your current and expected brackets.
Consider selling the business rather than the assets. In an asset sale, the seller keeps the recapture problem. In a stock sale, the buyer inherits the low basis and the recapture exposure travels with the company. This is one of several reasons buyers prefer asset deals and sellers prefer stock deals — negotiate the price accordingly.
Do not let the tax tail wag the equipment dog. Recapture claws back a deduction you already benefited from; it never makes the original write-off a net loss. The mistake is not claiming bonus depreciation — it is being surprised by the bill later.
Keep immaculate fixed-asset records. Every planning move above depends on knowing each asset's adjusted basis cold. A plain-text ledger where every asset purchase, depreciation entry, and sale is a timestamped, reviewable transaction makes this trivially auditable years later — see the Beancount documentation for how to structure one.
Keep Your Fixed Assets Organized From Day One
As you buy equipment and claim depreciation, maintaining clear records of cost, deductions, and adjusted basis is what turns a future sale from a scramble into a calculation.
