Nontaxable exchanges.   Certain exchanges of property are not taxable. This means any gain from the exchange is not recognized and you cannot deduct any loss. Your gain or loss will not be recognized until you sell or otherwise dispose of the property you receive.

Like-kind exchanges.   A like-kind exchange is the exchange of property for the same kind of property. It is the most common type of nontaxable exchange. To be a like-kind exchange, the property traded and the property received must be both of the following.

  Report the exchange of like-kind property on Form 8824, Like-Kind Exchanges. For more information about like-kind exchanges, see chapter 1 in Publication 544.

Installment sales.   An installment sale is a sale of property where you receive at least one payment after the tax year of the sale. If you finance the buyer's purchase of your property, instead of having the buyer get a loan or mortgage from a third party, you probably have an installment sale.

  For more information about installment sales, see Publication 537, Installment Sales.

Sale of a business.   The sale of a business usually is not a sale of one asset. Instead, all the assets of the business are sold. Generally, when this occurs, each asset is treated as being sold separately for determining the treatment of gain or loss.

  Both the buyer and seller involved in the sale of a business must report to the IRS the allocation of the sales price among the business assets. Use Form 8594, Asset Acquisition Statement Under Section 1060, to provide this information. The buyer and seller should each attach Form 8594 to their federal income tax return for the year in which the sale occurred.

  For more information about the sale of a business, see chapter 2 of Publication 544.

Basis.   The cost or purchase price of property is usually its basis for figuring the gain or loss from its sale or other disposition. However, if you acquired the property by gift, inheritance, or in some way other than buying it, you must use a basis other than its cost. For more information about basis, see Publication 551, Basis of Assets.

Adjusted basis.   The adjusted basis of property is your original cost or other basis plus certain additions, and minus certain deductions such as depreciation and casualty losses. In determining gain or loss, the costs of transferring property to a new owner, such as selling expenses, are added to the adjusted basis of the property.

Amount realized.   The amount you realize from a disposition is the total of all money you receive plus the fair market value of all property or services you receive. The amount you realize also includes any of your liabilities that were assumed by the buyer and any liabilities to which the property you transferred is subject, such as real estate taxes or a mortgage.

Fair market value.   Fair market value is the price at which the property would change hands between a buyer and a seller, neither having to buy or sell, and both having reasonable knowledge of all necessary facts.

Amount recognized.   Your gain or loss realized from a disposition of property is usually a recognized gain or loss for tax purposes. Recognized gains must be included in gross income. Recognized losses are deductible from gross income. However, a gain or loss realized from certain exchanges of property is not recognized. See Nontaxable exchanges, earlier. Also, you cannot deduct a loss from the disposition of property held for personal use.

You must classify your gains and losses as either ordinary or capital gains or losses. You must do this to figure your net capital gain or loss. Generally, you will have a capital gain or loss if you dispose of a capital asset. For the most part, everything you own and use for personal purposes or investment is a capital asset.

Certain property you use in your business is not a capital asset. A gain or loss from a disposition of this property is an ordinary gain or loss. However, if you held the property longer than 1 year, you may be able to treat the gain or loss as a capital gain or loss. These gains and losses are called section 1231 gains and losses.

For more information about ordinary and capital gains and losses, see chapters 2 and 3 in Publication 544.

If you have a capital gain or loss, you must determine whether it is long term or short term. Whether a gain or loss is long or short term depends on how long you own the property before you dispose of it. The time you own property before disposing of it is called the holding period.

For more information about short-term and long-term capital gains and losses, see chapter 4 of Publication 544.
