If more than one of the above exists, the circumstances may or may not constitute substantial evidence that the taxpayer held real property for sale in his business, depending upon the particular facts in each case.
A dealer in real property held a tract of land for sale to customers in the ordinary course of his business for 5 years. He then made a gift of it to his son. As a result of the operation of section 1223(2) the son will have held the property for the period of time required by section 1237. However, he will not qualify for the benefits of section 1237 because, there being no evidence to the contrary, the circumstances involved establish that the son holds the property for sale to customers, as did his father.
(a) The taxpayer's whole or half brothers and sisters, spouse, ancestors and lineal descendants.
(b) A corporation controlled by the taxpayer. A corporation is controlled by the taxpayer if he controls, as the result of direct ownership, constructive ownership, or otherwise, more than 50 percent of the corporation's voting stock.
(c) A partnership of which the taxpayer was a member at the time the improvements were made.
(d) A lessee if the improvement takes the place of a payment of rental income. See section 109 and the regulations thereunder.
(e) A Federal, State, or local government, or political subdivision thereof, if the improvement results in an increase in the taxpayer's basis for the property, as it would, for example, from a special tax assessment for paving streets.
A held a tract of land for 3 years during which he made substantial improvements thereon which substantially enhanced the value of every lot on the tract. A then made a gift of the tract to his son. The son made no further improvements on the tract but held it for 3 years and then sold several lots therefrom. The son is not entitled to the benefits of section 1237 since under section 1237(a)(2) he is deemed to have made the substantial improvements made by his father, and under section 1223(2) he is treated as having held the property for the period during which his father held it. Thus, the disqualifying improvements are deemed to have been made by the son while the tract was held by him. See paragraph (d) of this section for rules relating to the determination of the period for which the property is held.
(a) If a contract of sale obligates either the taxpayer or the buyer to make a substantial improvement which would substantially increase the value of the lot, the taxpayer may not claim the application of section 1237 unless the obligation to improve the lot ceases (for any reason other than that the improvement has been made) before or within the period, prescribed by section 6511, within which the taxpayer may file a claim for credit or refund of an overpayment of his tax on the gain from the sale of the lot. The following example illustrates this rule:
In 1956, A sells several lots from a tract he has subdivided for sale. Section 1237 would apply to the sales of these lots except that in the contract of sale, A agreed to install sewers, hard surface roads, and other utilities which would increase the value of the lots substantially. If in 1957, instead of requiring the improvements, the buyer releases A from this obligation, A may then claim the application of section 1237 to the sale of lots in 1956 in computing his income tax for 1956, since the period of limitations in which A may file a claim for credit or refund of an overpayment of his 1956 income tax has not expired.
(b) An improvement is made pursuant to a contract if the contract imposes an obligation on either party to make the improvement, but not if the contract merely places restrictions on the improvements, if any, either party may make. The following example illustrates this rule:
B sells several lots from a tract which he has subdivided. Each contract of sale prohibits the purchaser from building any structure on his lot except a personal residence costing $15,000 or more. Even if the purchasers build such residences, that does not preclude B from applying section 1237 to the sales of such lots, since the contracts did not obligate the purchasers to make any improvements.
(a) The taxpayer has held the property for 10 years. The full 10-year period must elapse, whether or not the taxpayer inherited the property. Although the taxpayer must hold the property 10 years, he need not hold it for 10 years after subdividing it. See paragraph (d) of this section for rules relating to the determination of the period for which the property is held.
(b) The improvement consists of the building or installation of water, sewer, or drainage facilities (either surface, sub-surface, or both) or roads, including hard surface roads, curbs, and gutters.
(c) The district director with whom the taxpayer must file his return is satisfied that, without such improvement, the lot sold would not have brought the prevailing local price for similar building sites.
(d) The taxpayer elects, as provided in subdivision (iii) of this subparagraph, not to adjust the basis of the lot sold or any other property held by him for any part of the cost of such improvement attributable to such lot and not to deduct any part of such cost as an expense.
A has been offered $500 per acre for a tract without roads, water, or sewer facilities which he has owned for 15 years. The adjacent tract has been subdivided and improved with water facilities and hard surface roads, and has sold for $4,000 per acre. The estimated cost of roads and water facilities on the adjacent tract is $2,500 per acre. The prevailing local price for similar building sites in the vicinity would be $1,500 per acre (i.e., $4,000 less $2,500). If A installed roads and water facilities at a cost of $2,500 per acre, his tract would sell for approximately $4,000 per acre. Under section 1237(b)(3) the installation of roads and water facilities does not constitute a substantial improvement if A elects to disregard the cost of such improvements ($2,500 per acre) in computing his cost or other basis for the lots sold from the tract, and in computing his basis for any other property owned by him.
Assume the same facts as in example (1) of this subdivision, except that A can obtain $1,600 per acre for his property without improvements. The installation of any substantial improvements would not constitute a necessary improvement under section 1237(b)(3), since the prevailing local price could have been obtained without any improvement.
Assume the same facts as in example (1) of this subdivision, except that the adjacent tract has also been improved with sewer facilities, the present cost of which is $1,200 per acre. The installation of the substantial improvements would not constitute a necessary improvement under section 1237(b)(3) on A's part, since the prevailing local price ($4,000 less the sum of $1,200 plus $2,500, or $300) could have been obtained by A without any improvement.
(a) The taxpayer shall submit:
(b) The election and the information required under (a) of this subdivision shall be submitted to the district director:
(c) Once made, the election as to the necessary improvement costs attributable to any lot sold shall be irrevocable and binding on the taxpayer unless the district director assesses an income tax as to such lot as if it were held for sale in the ordinary course of taxpayer's business. Under such circumstances, in computing gain, the cost or other basis shall be computed without regard to section 1237.
(a) The property in question was acquired by the taxpayer through the foreclosure of a lien thereon,
(b) The lien foreclosed secured the payment of an indebtedness to the taxpayer or (in the case of a corporation) secured the payment of an indebtedness to a creditor who has transferred the foreclosure bid to the taxpayer in exchange for all of the stock of the corporation and other consideration, and
(c) In the case of a corporate taxpayer, no shareholder of the corporation holds real property for sale to customers in the ordinary course of his trade or business or holds a controlling interest in another corporation which actually so holds real property, or which, but for the application of this subdivision, would be considered to so hold real property.
Thus, in the case of such property, it is not necessary for the taxpayer to satisfy the district director that the property would not have brought the prevailing local price without improvements or to elect not to add the cost of the improvements to his basis. In addition, if 80 percent or more of the real property owned by a taxpayer is property to which this subdivision applies, the requirements of (a) and (b) of this subdivision need not be met with respect to property adjacent to such property which is also owned by the taxpayer.
A held a tract of land for 3 years under circumstances otherwise qualifying for section 1237 treatment. He made a gift of the tract to B at a time when the fair market value of the tract exceeded A's basis for the tract. B held the tract for 2 more years under similar circumstances. B then sold 4 lots from the tract. B is entitled to the benefits of section 1237 since under section 1223(2) he held the lots for 5 years and all the other requirements of section 1237 are met.
C purchased all the stock in a corporation in 1955. The corporation purchased an unimproved tract of land in 1957. In 1961 the corporation was liquidated under section 333 and C acquired the tract of land. For purposes of section 1237, C's holding period commenced on the date the corporation actually acquired the land in 1957 and not on the date C purchased the stock.
Assume the selling price of the sixth lot of a tract is $10,000, the basis of the lot in the hands of the taxpayer is $5,000, and the expenses of sale are $750. The amount of gain realized by the taxpayer is $4,250, of which the amount of ordinary income attributable to the sale is zero, computed as follows:
| Selling price | $10,000 | |
| Basis | 5,000 | |
| Excess over basis | 5,000 | |
| 5 percent of selling price | 500 | |
| Expenses of sale | 750 | |
| Amount of gain realized treated as ordinary income | 0 | |
| Excess over basis | 5,000 | |
| 5 percent of selling price | 500 | |
| Excess of expenses over 5 percent of selling price | 250 | |
| 750 | ||
| Amount of gain realized from sale of property not held for sale in ordinary course of business | 4,250 | |
Assume the same facts as in Example 1, except that the expenses of sale of such sixth lot are $300. The amount of gain realized by the taxpayer is $4,700, of which the amount of ordinary income attributable to the sale is $200, computed as follows:
| Selling price | $10,000 | |
| Basis | 5,000 | |
| Excess over basis | 5,000 | |
| 5 percent of selling price | $500 | |
| Expenses of sale | 300 | |
| Amount of gain realized treated as ordinary income | 200 | |
| Excess over basis | 5,000 | |
| 5 percent of selling price | 500 | |
| Excess of expenses over 5 percent of selling price | 0 | |
| 500 | ||
| Amount of gain realized from sale of property not held for sale in ordinary course of business | 4,500 | |
