IRS Publication 544: Sales and Other Dispositions of Assets

IRS Publication 544 is the agency’s guide to how federal tax law treats the sale, exchange, or other disposition of property, from stocks and personal belongings to business equipment and commercial real estate. The outcome of any disposition turns on three variables: how the asset is classified, what your basis is, and how long you held it. Get any of those wrong and the result can swing by thousands of dollars, usually in the wrong direction.¹

How the Publication Classifies Your Property

Every asset you dispose of falls into one of three categories, and the category controls the tax rate on any gain or loss.

Capital Assets

A capital asset is essentially any property you own that isn’t on a short list of statutory exclusions. Stocks, bonds, a personal residence, jewelry, a car used for personal purposes, and collectibles all qualify. The statute defines the category by what it leaves out: inventory and goods held for sale to customers, depreciable business property, certain creative works in the hands of their creator, business receivables, government publications received for free, certain commodity derivative instruments, hedging transactions, and business supplies.²

Ordinary Assets

Ordinary assets produce income or loss taxed at your regular income rates. Inventory, goods held primarily for sale to customers, and accounts or notes receivable from the business are the usual examples. A loss on an ordinary asset offsets other ordinary income dollar for dollar, without the annual caps that apply to capital losses.

Section 1231 Property

Section 1231 sits between the other two and can give you the best of both. It covers depreciable property and real estate used in a trade or business and held for more than one year. If your Section 1231 gains for the year exceed your Section 1231 losses, the net gain is treated as long-term capital gain. If the losses win, the net loss is treated as an ordinary loss that fully offsets other income. You aggregate the transactions on Form 4797.³⁴

There is a catch. If this year’s Section 1231 transactions produce a net gain, you must look back at the five preceding tax years. Any net Section 1231 losses you deducted as ordinary losses in that window get recaptured by recharacterizing an equal amount of this year’s net gain as ordinary income. Only the portion above the unrecaptured prior losses qualifies for long-term capital gains treatment. The rule stops you from taking ordinary losses in bad years and capital gains in good ones, and it’s easy to miss if you aren’t tracking prior-year results.

Figuring Your Basis

Your basis is your investment in the property for tax purposes, and it’s what gets subtracted from sale proceeds to calculate gain or loss. Most people start with purchase price, but inherited and gifted property follow different rules.

Property You Bought

For purchased property, basis starts with what you paid, including sales tax and settlement or closing costs tied to the purchase. Capital improvements and special assessments raise it. Depreciation claimed on business property, casualty loss deductions, and nontaxable distributions lower it. The result after adjustments is your adjusted basis.

Inherited Property

Property acquired from someone who died generally receives a stepped-up basis equal to fair market value on the date of death. If your parent paid $10,000 for stock worth $200,000 at death, your basis is $200,000, and the lifetime appreciation is wiped out for income tax purposes. An executor can elect an alternate valuation date six months after death if that would reduce the estate’s overall tax.⁵

Gifted Property

Gifted property carries a dual-basis rule. For calculating a gain, your basis is the donor’s adjusted basis at the time of the gift. If the fair market value at the time of the gift was lower than the donor’s basis, you use that fair market value as your basis for calculating a loss. Sell for a price between the two numbers and you recognize neither gain nor loss.⁶

Calculating Gain or Loss

The formula is simple: amount realized minus adjusted basis. The work is in getting the inputs right and then applying the correct treatment to the result.

Amount Realized

Amount realized is everything you receive from the disposition. Cash is the obvious piece, but it also includes the fair market value of property or services you receive and any liabilities the buyer takes on. Sell a rental building with a $150,000 mortgage the buyer assumes, and that $150,000 is part of your amount realized even though you never touched the money. Selling expenses (brokerage commissions, legal fees, title insurance, transfer costs) come off the top before the comparison to basis.

Holding Period and Rate

Property held one year or less produces short-term capital gain taxed at ordinary income rates. More than a year, and you get long-term treatment at the 0%, 15%, or 20% rate depending on taxable income and filing status.⁷ Ordinary assets like inventory and receivables always produce ordinary gain or loss regardless of holding period. Section 1231 assets have to clear the one-year mark to qualify for the favorable netting.

Depreciation Recapture

When you depreciate a business asset, each year’s deduction reduces ordinary income. If you later sell for more than the depreciated value, some or all of the gain is pulled back into ordinary income so that ordinary deductions don’t quietly convert into capital gains. Recapture is calculated on Form 4797.⁸

Section 1245: Full Recapture on Equipment and Similar Assets

Section 1245 covers tangible personal property used in a business: equipment, machinery, vehicles, furniture. On a sale at a gain, the entire gain is ordinary income up to the total depreciation and Section 179 expensing you claimed. Only gain beyond that total gets Section 1231 treatment. Because business personal property rarely appreciates above its original cost, recapture usually swallows the whole gain.⁹

Section 1250: Excess Depreciation on Real Property

Section 1250 covers depreciable real property such as commercial buildings and rental structures. Recapture here is limited to additional depreciation, meaning the amount by which the depreciation you actually claimed exceeds what straight-line would have produced.¹⁰ Real property placed in service after 1986 generally must use straight-line, so there is usually no excess to recapture. For older buildings depreciated under accelerated methods, the math still matters.

Unrecaptured Section 1250 Gain

Even when there is no Section 1250 recapture, the straight-line depreciation you claimed on real property doesn’t entirely escape. The gain attributable to that depreciation is called unrecaptured Section 1250 gain and is taxed at a maximum rate of 25%, higher than the usual 15% or 20% long-term rate.⁷ Selling a fully depreciated rental building can produce three tax layers: unrecaptured Section 1250 gain at 25%, remaining long-term capital gain at 15% or 20%, and any actual Section 1250 recapture at ordinary rates. The numbers flow from Form 4797 to Schedule D.

Deferral, Timing, and Loss-Disallowance Rules

Not every disposition is a cash sale on the spot. Publication 544 covers several provisions that shift timing, defer gain, or disallow a loss. Missing one can push tax forward or kill a deduction.

Installment Sales

If you sell property and receive at least one payment after the year of sale, you generally report the gain under the installment method, spreading the taxable gain across the years you receive payments. You calculate a gross profit percentage (total gain divided by contract price) and apply it to each year’s principal payments. Report on Form 6252.¹¹

Two exceptions matter. Dealer dispositions (property held for sale to customers, like a developer selling lots) cannot use the installment method. And any depreciation recapture under Sections 1245 or 1250 must be recognized in the year of sale regardless of when payments arrive; only the gain above the recapture spreads out.

Involuntary Conversions

When property is destroyed, stolen, or condemned, you can defer the gain by reinvesting the proceeds in replacement property similar in use. Reinvest the full amount received and no gain is recognized. Reinvest less and gain is recognized only to the extent of the shortfall.¹²

You generally have two years from the close of the first tax year in which gain is realized to buy the replacement. Condemned real property held for business or investment use gets three years. Property in a federally declared disaster area may qualify for four.

Like-Kind Exchanges

Section 1031 lets you swap real property held for business use or investment without recognizing gain, if the rules are followed to the letter. Since 2018, the provision applies only to real property; exchanges of equipment, vehicles, or other personal property no longer qualify.¹³

Timing is strict. You have 45 calendar days from transferring the relinquished property to identify potential replacement properties, and 180 calendar days from the transfer (or the due date of your return including extensions, whichever comes first) to close. Miss either deadline and the full gain becomes taxable. Most exchanges use a qualified intermediary to hold the proceeds, because touching the funds yourself can also disqualify the transaction.

Abandonment

When you abandon business property rather than selling it, the loss is treated as ordinary, even if a sale would have produced a capital loss. Abandonment isn’t a sale or exchange, so the capital loss limits don’t apply. You report it on Form 4797. The deduction requires that you permanently give up possession and use with no expectation of receiving anything in return.

The Wash Sale Rule

Sell stock or securities at a loss and buy substantially identical shares within 30 days before or after the sale, and the loss is disallowed. The 61-day window (30 days each side plus the sale date) prevents loss-harvesting while holding essentially the same position. The disallowed loss isn’t lost for good; it’s added to the basis of the replacement shares, deferring the benefit until you sell those shares without triggering another wash sale.¹⁴

The 3.8% Net Investment Income Tax

Higher-income taxpayers face an additional 3.8% tax on net investment income, which includes capital gains from asset dispositions. The tax applies to the lesser of your net investment income or the amount by which your modified adjusted gross income exceeds the threshold for your filing status.¹⁵

The thresholds don’t adjust for inflation:

Married filing jointly: $250,000
Single or head of household: $200,000
Married filing separately: $125,000

Net investment income for this purpose includes capital gains, interest, dividends, rental income, royalties, and income from passive business activities. It doesn’t include wages, self-employment income, or gains from an active trade or business in which you materially participate, unless that business trades financial instruments or commodities. A married couple selling a rental with $400,000 of gain can face the 15% or 20% capital gains rate, the 25% rate on unrecaptured depreciation, and a 3.8% surtax layered on top.

Which Forms You File

The form depends on the type of asset:

Form 8949 and Schedule D: capital asset sales. Form 8949 reconciles the proceeds reported on Forms 1099-B and 1099-S with the amounts on your return. Totals flow to Schedule D.
Form 4797: sales of business property, including Section 1231 netting and recapture under Sections 1245 and 1250.
Form 6252: installment sale income.
Form 8824: like-kind exchanges.
Form 4684: casualties and thefts.

¹⁶

Failing to report a disposition, or underreporting the gain, can trigger the accuracy-related penalty of 20% of the underpaid tax. The penalty applies when the underpayment results from negligence or a substantial understatement of income tax; for individuals, substantial means an understatement greater than 10% of the correct tax or $5,000, whichever is larger.¹⁷ Interest runs from the original due date and compounds until the balance is paid. Because the IRS receives copies of Forms 1099-B and 1099-S directly from brokers and closing agents, unreported dispositions are among the easiest items for the agency’s matching system to flag.

What Publication 544 Doesn’t Cover

The exclusion of up to $250,000 of gain on the sale of a principal residence ($500,000 for joint filers) is addressed in Publication 523, not Publication 544. If you sold a home that you also rented or used as a home office, the depreciation you claimed on the business portion still has to be recaptured as ordinary income even when the rest of the gain qualifies for the exclusion, so Publication 544’s basis and recapture rules still touch the transaction.¹⁸
