How to Write Off a Fully Depreciated Asset: Recapture and Form 4797

To write off a fully depreciated asset, post a journal entry that debits accumulated depreciation for the full original cost and credits the asset account for the same amount, then report any proceeds on Form 4797. The bookkeeping is the easy part. The tax side is where people get caught: if you receive anything for the asset, depreciation recapture generally taxes that amount as ordinary income up to the original cost, not at capital gains rates.

What Fully Depreciated Means on Your Books

A fully depreciated asset still sits on your balance sheet even after its book value hits zero. The original cost and the matching accumulated depreciation both stay recorded until you take action to remove them. A $50,000 piece of equipment depreciated over five years shows up as $50,000 in asset cost offset by $50,000 in accumulated depreciation. The net is zero, but both line items remain.

The machine itself might still run fine for years. Until you retire, sell, or trade it, it stays on the ledger in this suspended state. Removing it takes a deliberate journal entry, and in most cases a tax filing too.

Scrapping or Retiring the Asset for Nothing

The simplest write-off happens when you pull a fully depreciated asset out of service without receiving anything for it. Debit accumulated depreciation for the full original cost and credit the asset account for the same amount. Both accounts drop to zero, and the asset disappears from your fixed-asset ledger.

For a machine that originally cost $10,000 with $10,000 in accumulated depreciation, the entry is a $10,000 debit to Accumulated Depreciation—Machinery and a $10,000 credit to the Machinery account. Book value was already zero and no cash changed hands, so nothing hits the income statement. It’s balance-sheet cleanup.

If you pay someone to haul away or dispose of the asset, that cost flows through the income statement. A $500 disposal fee creates a $500 debit to Loss on Disposal and a $500 credit to Cash. The reverse also happens: if a scrap dealer pays you $200, you record a $200 debit to Cash and a $200 credit to Gain on Disposal. Any amount you receive for a zero-book-value asset is pure gain on the books.

Abandonment has a specific meaning for tax purposes. You must voluntarily and permanently give up possession and use of the property with the intent to end your ownership, without transferring it to anyone else.¹ Letting equipment sit idle in a warehouse doesn’t qualify. If the asset has zero adjusted basis and you abandon it without receiving anything, there is no gain or loss to report.

Selling a Fully Depreciated Asset

When you sell a fully depreciated asset for cash, the entire amount you receive is a gain because the book value is zero. The journal entry debits Cash for the sale price, debits Accumulated Depreciation for the original cost, credits the Asset account for the original cost, and credits Gain on Disposal for whatever you collected.

If that old $10,000 machine sells for $1,500, you record a $1,500 debit to Cash and a $1,500 credit to Gain on Disposal, alongside the entries clearing the asset history. The gain shows up on your income statement, and it creates a tax obligation. Read the recapture section below before assuming the tax bill will be small.

Trading It In

A trade-in swaps the old asset toward a new one, usually with additional cash. Under GAAP, you generally recognize any gain or loss based on the fair market value of what you received, as long as the exchange has commercial substance. The entry debits the new asset at its fair value, debits Accumulated Depreciation on the old asset, credits the old Asset account, credits Cash for the additional amount paid, and credits any recognized Gain on Disposal.

On the tax side, trade-ins of equipment and other personal property follow normal sale rules since the 2017 tax law change. Like-kind exchange treatment under Section 1031 now applies only to real property.² Trading a fully depreciated forklift for a newer model is treated the same as selling the old one and buying the new one separately. Any trade-in value above the zero book value triggers depreciation recapture.

Depreciation Recapture Is Where the Tax Bill Comes From

When you sell a fully depreciated asset for a gain, the IRS does not tax that gain at capital gains rates. Depreciation recapture rules claw back the tax benefit you got from deducting depreciation over the years, taxing it as ordinary income when you sell.¹

Section 1245 Property: Equipment, Vehicles, Furniture

Section 1245 covers tangible personal property like machinery, vehicles, and furniture. When you sell Section 1245 property, gain is treated as ordinary income up to the total depreciation you previously claimed.³ For a fully depreciated asset, every dollar of the sale price up to the original cost is ordinary income.

Buy a machine for $10,000, depreciate it fully, sell it for $8,000. The entire $8,000 gain is Section 1245 recapture at your ordinary income rate. No capital gains treatment on any of it.

Section 1250 Property: Buildings

Section 1250 covers depreciable real property like commercial buildings and rental structures. Since straight-line has been required for real property placed in service after 1986, actual Section 1250 recapture as ordinary income is usually zero.¹

That doesn’t mean the depreciation escapes tax. Gain attributable to straight-line depreciation on real property is taxed as “unrecaptured Section 1250 gain” at a maximum rate of 25% for individuals.¹ That sits between ordinary income rates (up to 37%) and long-term capital gains rates (0%, 15%, or 20%).

Section 179 and Bonus Depreciation Get Recaptured Too

Many owners expense the full cost of equipment in the year of purchase using the Section 179 deduction, which allows up to $2,560,000 in immediate write-offs for 2026. If you took Section 179 and later sell the asset, all of that expensed amount counts as depreciation for recapture. The entire deduction is subject to Section 1245 recapture as ordinary income when you sell at a gain.³

Expensed a $50,000 truck under Section 179 in 2022 and sell it for $20,000 in 2026? The whole $20,000 is ordinary income, not capital gain. The statute defines “recomputed basis” as adjusted basis plus all depreciation adjustments, and Section 179 is in that calculation. Bonus depreciation works the same way.

There’s also a separate recapture trigger if business use of a Section 179 asset drops to 50% or below in any year during the recovery period. Report that on Part IV of Form 4797 by calculating the difference between the Section 179 deduction taken and the depreciation you would have been entitled to under normal MACRS rules.⁴

Selling Above Original Cost, and the Five-Year Lookback

In the rarer case where a fully depreciated asset sells for more than its original cost, the excess above original cost escapes Section 1245 recapture and is classified as a Section 1231 gain. Section 1231 gains get treated as long-term capital gains when your total Section 1231 gains for the year exceed your Section 1231 losses.⁵

A machine bought for $10,000, fully depreciated to zero, and sold for $12,000 produces a $12,000 total gain. The first $10,000 is Section 1245 recapture at ordinary rates. The remaining $2,000 qualifies as a Section 1231 gain, potentially at capital gains rates.¹

Watch for the five-year lookback rule. If you claimed net Section 1231 losses in the previous five tax years, current-year Section 1231 gains are recharacterized as ordinary income up to the amount of those prior losses. Congress added this to prevent taxpayers from deducting Section 1231 losses as ordinary and then reporting later Section 1231 gains at capital gains rates. Check recent returns before assuming favorable treatment.

Reporting the Disposal on Form 4797

Every sale or disposition of depreciable business property gets reported on Form 4797, Sales of Business Property.⁶ The form runs the recapture math and determines how much of the gain is ordinary versus capital. Losses on business property are also reported here and are generally deductible as ordinary losses against other income.

Form 4797 is filed with your regular income tax return, so the deadline depends on your entity. For calendar-year taxpayers, partnerships and S corporations must file by March 15, C corporations file by April 15.⁷ Sole proprietors file Form 4797 with their personal Form 1040, due April 15. Extensions are available, but the gain or loss is recognized in the tax year the disposal occurs, not the year you file.

Records to Keep After the Write-Off

Keep property records until the statute of limitations expires for the tax year in which you dispose of the asset.⁸ For most returns that means at least three years after filing. The period extends to six years if you underreport income by more than 25% of gross income, and to seven years if you claim a loss from worthless securities or bad debt.

Hold on to the original purchase documentation, depreciation schedules, and disposal records (sale agreement, scrap receipt, or written record of abandonment) for the full retention period. You need them to substantiate both the depreciation you claimed and the gain or loss you reported on disposal. If you never file a return for the year of disposal, or file a fraudulent return, there is no statute of limitations and records should be kept indefinitely.⁸

Don’t Forget Local Property Tax

In many jurisdictions, business equipment and other tangible personal property are subject to local property tax assessments. When you dispose of a fully depreciated asset, report the removal on your next annual personal property tax return filed with the local assessor. Skip it and you may keep paying property tax on equipment you no longer own. Filing deadlines and notification requirements vary by locality, so check with your county or municipal assessor to confirm the process in your area.
