If the gains to which section 1231 applies exceed the losses to which the section applies, the gains and losses are treated as long-term capital gains and losses and are subject to the provisions of parts I and II (section 1201 and following), subchapter P, chapter 1 of the Code, relating to capital gains and losses. If the gains to which section 1231 applies do not exceed the losses to which the section applies, the gains and losses are treated as ordinary gains and losses. Therefore, in the latter case, a loss from the involuntary conversion of a capital asset held for more than 1 year (6 months for taxable years beginning before 1977; 9 months for taxable years beginning in 1977) is treated as an ordinary loss and is not subject to the limitation on capital losses in section 1211. The phrase involuntary conversion is defined in paragraph (e) of this section.
For purposes of section 1231, the phrase property used in the trade or business means property described in this paragraph (other than property described in subparagraph (2) of this paragraph). Notwithstanding any of the provisions of this paragraph, section 1231(a) does not apply to gains and losses under the circumstances described in paragraph (e) (2) or (3) of this section.
A, an individual, makes his income tax return on the calendar year basis. A's recognized gains and losses for 1957 of the kind described in section 1231 are as follows:
| Gains | Losses | |
|---|---|---|
| 1. Gain on sale of machinery, used in the business and subject to an allowance for depreciation, held for more than 6 months | $4,000 | |
| 2. Gain reported in 1957 (under section 453) on installment sale in 1956 of factory premises used in the business (including building and land, each held for more than 6 months) | 6,000 | |
| 3. Gain reported in 1957 (under section 453) on installment sale in 1957 of land held for more than 6 months, used in the business as a storage lot for trucks | 2,000 | |
| 4. Gain on proceeds from requisition by Government of boat, held for more than 6 months, used in the business and subject to an allowance for depreciation | 500 | |
| 5. Loss upon the destruction by fire of warehouse, held for more than 6 months and used in the business (excess of adjusted basis of warehouse over compensation by insurance, etc.) | $3,000 | |
| 6. Loss upon theft of unregistered bearer bonds, held for more than 6 months | 5,000 | |
| 7. Loss in storm of pleasure yacht, purchased in 1950 for $1,800 and having a fair market value of $1,000 at the time of the storm | 1,000 | |
| 8. Total gains | 12,500 | ___ |
| 9. Total losses | 9,000 | |
| 10. Excess of gains over losses | 3,500 |
Since the aggregate of the recognized gains ($12,500) exceeds the aggregate of the recognized losses ($9,000), such gains and losses are treated under section 1231 as gains and losses from the sale or exchange of capital assets held for more than 6 months. For any taxable year beginning after December 31, 1957, and before January 1, 1970, the $5,000 loss upon theft of bonds (item 6) would not be taken into account under section 1231. See paragraph (e)(2) of this section.
If in example (1), A also had a loss of $4,000 from the sale under threat of condemnation of a capital asset acquired for profit and held for more than six months, then the gains ($12,500) would not exceed the losses ($9,000 plus $4,000, or $13,000). Neither the loss on that sale nor any of the other items set forth in example (1) would then be treated as gains and losses from the sale or exchanges of capital assets, but all of such items would be treated as ordinary gains and losses. Likewise, if A had no other gain or loss, the $4,000 loss would be treated as an ordinary loss.
A's yacht, used for pleasure and acquired for that use in 1945 at a cost of $25,000, was requisitioned by the Government in 1957 for $15,000. A sustained no loss deductible under section 165(c) and since no loss with respect to the requisition is recognizable, the loss will not be included in the computations under section 1231.
A, an individual, makes his income tax return on a calendar year basis. During 1970 trees on A's residential property which were planted in 1950 after the purchase of such property were destroyed by fire. The loss, which was in the amount of $2,000 after applying section 165(c)(3), was not compensated for by insurance or otherwise. During the same year A also recognized a $1,500 gain from insurance proceeds compensating him for the theft sustained in 1970 of a diamond brooch purchased in 1960 for personal use. A has no other gains or losses for 1970 from the involuntary conversion of property. Since the recognized losses exceed the recognized gains from the involuntary conversion for 1970 as a result of fire, storm, shipwreck, or other casualty, or from theft, of any property used in the trade or business or of any capital asset held for more than 6 months, neither the gain nor the loss is included in making the computations under section 1231.
The facts are the same as in example (4), except that A also recognized a gain of $1,000 from insurance proceeds compensating him for the total destruction by fire of a truck, held for more than 6 months, used in A's business and subject to an allowance for depreciation. A has no other gains or losses for 1970 from the involuntary conversion of property. Since the recognized losses ($2,000) do not exceed the recognized gains ($2,500) from the involuntary conversion for 1970 as a result of fire, storm, shipwreck, or other casualty, or from theft, of any property used in the trade or business or of any capital asset held for more than 6 months, such gains and losses are included in making the computations under section 1231. Thus, if A has no other gains or losses for 1970 to which section 1231 applies, the gains and losses from these involuntary conversions are treated under section 1231 as gains and losses from the sale or exchange of capital assets held for more than 6 months.
The facts are the same as in example (5) except that A also has the following recognized gains and losses for 1970 to which section 1231 applies:
| Gains | Losses | |
|---|---|---|
| Gain on sale of machinery, used in the business and subject to an allowance for depreciation, held for more than 6 months | $4,000 | |
| Gain reported in 1970 (under section 453) on installment sale in 1969 of factory premises used in the business (including building and land, each held for more than 6 months) | 6,000 | |
| Gain reported in 1970 (under section 453) on installment sale in 1970 of land held for more than 6 months, used in the business as a storage lot for trucks | $2,000 | |
| Loss upon the sale in 1970 of warehouse, used in the business and subject to an allowance for depreciation, held for more than 6 months | $5,000 | |
| Total gains | 12,000 | _____ |
| Total losses | 5,000 |
Since the aggregate of the recognized gains ($14,500) exceeds the aggregate of the recognized losses ($7,000), such gains and losses are treated under section 1231 as gains and losses from the sale or exchange of capital assets held for more than 6 months.
B, an individual, makes his income tax return on the calendar year basis. During 1970 furniture used in his business and held for more than 6 months was destroyed by fire. The recognized loss, after compensation by insurance, was $2,000. During the same year B recognized a $1,000 gain upon the sale of a parcel of real estate used in his business and held for more than 6 months, and a $6,000 loss upon the sale of stock held for more than 6 months. B has no other gains or losses for 1970 from the involuntary conversion, or the sale or exchange of, property. The $6,000 loss upon the sale of stock is not a loss to which section 1231 applies since the stock is not property used in the trade or business, as defined in section 1231(b). The $2,000 loss upon the destruction of the furniture is not a loss to which section 1231 applies since the recognized losses ($2,000) exceed the recognized gains ($0) from the involuntary conversion for 1970 as a result of fire, storm, shipwreck, or other casualty, or from theft, of any property used in the trade or business or of any capital asset held for more than 6 months. Accordingly, the $1,000 gain upon the sale of real estate is considered to be gain from the sale or exchange of a capital asset held for more than 6 months since the gains ($1,000) to which section 1231 applies exceed the losses ($0) to which such section applies.
The facts are the same as in example (7) except that B also recognized a gain of $4,000 from insurance proceeds compensating him for the total destruction by fire of a freighter, held for more than 6 months, used in B's business and subject to an allowance for depreciation. Since the recognized losses ($2,000) do not exceed the recognized gains ($4,000) from the involuntary conversion for 1970 as a result of fire, storm, shipwreck, or other casualty, or from theft, of any property used in the trade or business or of any capital asset held for more than 6 months, such gains and losses are included in making the computations under section 1231. Since the aggregate of the recognized gains to which section 1231 applies ($5,000) exceeds the aggregate of the recognized losses to which such section applies ($2,000), such gains and losses are treated under section 1231 as gains and losses from the sale or exchange of capital assets held for more than 6 months. The $6,000 loss upon the sale of stock is not taken into account in making such computation since it is not a loss to which section 1231 applies.
