The period ends on the date the last item of new section 38 property that is part of that unit is available to be placed in service. Property that is not new section 38 property, such as a building, is not considered part of an integrated unit for purposes of determining the normal construction period of that unit. For example, if a manufacturing plant has a normal construction period of two years or more but the equipment (i.e., new section 38 property) to be installed in the plant has a normal construction period of less than two years, the plant and the equipment do not constitute an integrated unit with a construction period of two years or more and the equipment is not progress expenditure property.
On July 1, 1974, corporation X begins physical work on construction of a machine with an estimated useful life when placed in service of more than 7 years. For its taxable year ending June 30, 1975, X makes an election under section 46(d). For purposes of determining on June 30, 1975, whether the machine is “progress expenditure property”, the normal construction period is treated as having begun on January 22, 1975. Thus, the machine will be considered to be progress expenditure property on June 30, 1975, only if the estimated time required to complete construction after June 30 is at least 18 months and 22 days (i.e., 2 years less the period January 22, 1975, through June 30, 1975).
(i) Corporation X constructs a pipeline in two sections and simultaneously begins physical work on construction of each section on January 1, 1976. One section extends from city M to city N. The other extends from city N to city O. Oil will be transferred to storage tanks at both city N and city O. Corporation X also begins construction on January 1, 1976, of a pumping station necessary to the operation of the pipeline from city M to city N. Construction of a pumping station necessary to the operation of the pipeline from city N to city O begins on June 30, 1977. For 1976, corporation X makes an election under section 46(d).
(ii) The section of pipeline from city M to city N and the associated pumping station will be available to be placed in service on January 1, 1977. Construction of the section of the pipeline from city N to city O will be completed on June 30, 1977. However, that section of the pipeline will not be available to be placed in service until completion of the associated pumping station on January 1, 1978.
(iii) The section of pipeline from city M to city N and the section from city N to city O must be considered separately in determining the normal construction period of the property. Each section will be placed in service separately. However, each section of the pipeline and the associated pumping station may be considered an integrated unit. The pumping stations are essential to the operation of each section of pipeline. Each section of pipeline and the associated pumping station are placed in service at the same time.
(iv) The section of pipeline from city M to city N and the associated pumping station are not progress expenditure property, because the normal construction period of that unit is only 1 year (January 1, 1976 to January 1, 1977).
(v) The section of pipeline from city N to city O and the associated pumping station are progress expenditure property, because the normal construction of that integrated unit is 2 years (January 1, 1976 to January 1, 1978). It is immaterial that neither the construction period of that section of pipeline (January 1, 1976 to June 30, 1977) nor the construction period of the associated pumping station (June 30, 1977 to January 1, 1978) is 2 years.
(vi) Assume the pumping station associated with the pipeline from city N to city O includes backup pumping equipment that will be used only if the primary pumping equipment fails. The backup equipment is part of the integrated unit because it serves to effect the safe or efficient performance of the unit.
(See, however, section 46(d)(4)(A) and paragraph (h)(3)(i) of this section, relating to the time when amounts for component parts and materials are properly chargeable to capital account);
(i) Corporation X agrees to build an airplane for corporation Y, a calendar year taxpayer. The airplane is non-self-constructed progress expenditure property. Physical work on construction begins on January 1, 1980. The normal construction period for the airplane is five years and the airplane is delivered and placed in service on December 31, 1984.
(ii) The cost of construction to corporation X is $500,000. The contract price is $550,000. Corporation Y makes a $110,000 payment in each of the years 1980 and 1981, an $85,000 payment in 1982, a $135,000 payment in 1983, and a $110,000 payment in 1984.
(iii) For 1980, corporation Y makes an election under section 46(d). Progress is presumed to occur ratably over the 5-year construction period, which is 20 percent in each year. Twenty percent of the contract price is $110,000. The percentage of completion limitation for each year, thus, is $110,000.
(iv) For each of the years 1980 and 1981, the $110,000 payments may be treated as qualified progress expenditures. The payments equal the percentage of completion limitation.
(v) For 1982, the $85,000 payment may be treated as a qualified progress expenditure, because it is less than the percentage of completion limitation. The excess of the percentage of completion limitation ($110,000) over the 1982 payment ($85,000) is added to the percentage of completion limitation for 1983. One hundred and ten thousand dollars minus $85,000 equals $25,000. Twenty-five thousand dollars plus $110,000 equals $135,000, which is the percentage of completion limitation for 1983.
(vi) For 1983, the entire $135,000 payment may be treated as a qualified progress expenditure. The payment equals the percentage of completion limitation for 1983.
(vii) For 1984, no qualified progress expenditures may be taken into account, because the airplane is placed in service in that year.
(viii) See example 2 of paragraph (r)(4) of this section for the result if Y sells its contract rights to the property on December 31, 1982.
(i) Corporation X contracts to build a ship for partnership AB that qualifies as progress expenditure property. The contract price is $100,000. Physical work on construction of the ship begins on January 1, 1980. The ship is placed in service on December 31, 1983.
(ii) The AB partnership reports income on the calendar year basis. Partners A and B share profits equally. For A's taxable year ending December 31, 1980, A makes an election under section 46(d) B does not make the election.
(iii) For each of the years 1980, 1981, 1982, and 1983, the AB partnership makes $25,000 payments to corporation X. The payments made in 1980, 1981, and 1982 are qualified progress expenditures. The 1983 payment is not a qualified progress expenditure, because the ship is placed in service in that year.
(iv) For each of the years 1980, 1981, and 1982, A may take into account qualified progress expenditures of $12,500 because A had a 50 percent partnership interest in each of those years.
(v) For 1983, qualified investment for the ship is $100,000. A and B's share are $50,000 each, because each had a 50 percent partnership interest in 1983. However, A must reduce its $50,000 share for 1983 by $37,500, the amount of qualified progress expenditures taken into account by A. B's share is not reduced, because B did not take into account qualified progess expenditures.
(i) The facts are the same as in example 1 except that on June 30, 1983, the partnership agreement is amended to admit a new partner, C. The partners agree to share profits equally. There is no special allocation in effect under section 704 with respect to the ship.
(ii) For each of the years 1980, 1981, and 1982, A may take into account qualified progress expenditures of $12,500 because A has a 50 percent partnership interest in those years.
(iii) For 1983, A, B, and C's share of qualified investment is $33,333 each, because each had a 33 1/3 percent partnership interest in that year. A must reduce its share to zero, because it took $37,500 into account as qualified progress expenditures. In addition, the excess of the $37,500 over the $33,333 applied as a reduction is subject to recapture under section 47(a)(3)(B). B and C's shares are not reduced, because neither taxpayer took into account qualified progress expenditures.
(i) Corporation X contracts with A on January 1, 1976, to build an electric generator that qualifies as non-self-constructed progress expenditure property. A will build the generator at a cost of $125,000. Corporation X agrees to pay A $150,000. Corporation X reports income on the calendar year basis. Corporation X makes an election under section 46(d) for 1976. Physical work on construction begins on January 1, 1976. Corporation X makes payments of $30,000 to A for construction of the generator in each of the years 1976, 1977, 1978, 1979, and 1980. A incurs a cost of $25,000 in each of those years for construction of the property. The property is placed in service in 1980.
(ii) For 1976, X may increase qualified investment by $12,000, 40 percent of the payment made in 1976.
(iii) For 1977, corporation X may increase qualified investment by $24,000. Eighteen thousand dollars of that amount is 60 percent of the 1977 payment. The remaining $6,000 is 20 percent of the $30,000 payment made in 1976.
(iv) For 1978, corporation X may increase qualified investment by $36,000. Twenty-four thousand dollars of that amount is 80 percent of the 1978 payment. The remaining $12,000 is 20 percent of the $30,000 payment made in 1976, plus 20 percent of the $30,000 payment made in 1977.
(v) For 1979, corporation X may increase qualified investment by $48,000. Thirty thousand dollars of that amount is 100 percent of the 1979 payment. The remaining $18,000 of that amount is 20 percent of the $30,000 payments made in each of the years 1976, 1977, and 1978.
(vi) Qualified investment for corporation X for 1980 is $30,000. The $30,000 is the basis (or cost) of the generator ($150,000), reduced by qualified progress expenditures allowed with respect to that property ($120,000).
Once the status of the property as self-constructed or non-self-constructed property in the hands of the transferee has been determined, all rules under this section for determining the amount of qualified progress expenditures for that type of property apply. For example, if the property is non-self-constructed in the hands of the transferee, amounts merely incurred (but not paid) for the transfer are not taken into account as qualified progress expenditures. Actual payment is necessary (see paragraph (j)(3) of this section). In applying section 46(d)(3)(B)(ii), the amount paid or incurred for the transfer (to the extent that it qualifies as a payment for construction under the first sentence of this paragraph (r)(3)(ii)) is considered to be part of the overall cost to the transferee of construction by another person, and the portion of construction which is completed during the taxable year is determined by taking into account construction that was completed before the constructed property was acquired by the transferee. If the transferee makes an election under section 46(d) and this section for the taxable year in which the transfer occurs, then for purposes of applying the presumption in section 46(d)(4)(D) that construction is deemed to occur not more rapidly than ratably over the normal construction period, the transferee's normal construction period is considered to have begun on the date on which physical work on construction of the acquired property began.
Corporation X begins physical work on construction of progress expenditure property for corporation Y on January 1, 1976. Y accurately estimates a 3-year normal construction period and elects under section 46(d) on its return for its taxable year ending December 31, 1976. On January 1, 1978, Y sells the contract rights for construction of the property to corporation Z, which uses a fiscal year ending June 30. Qualified progress expenditures allowed to Y in 1976 and 1977 are subject to recapture under section 47(a)(3). Because Z's normal construction period for the property is less than 2 years (January 1, 1978 to January 1, 1979), the property is not progress expenditure property in Z's hands. Z may not elect progress expenditure treatment for the property.
(i) Assume the same facts as in the example in paragraph (j)(7) of this section, except, on December 31, 1982, Y sells its contract rights to the property for $340,000 to corporation Z, which also uses the calendar year. Z pays Y the full $340,000 on that date. The property is still to be placed in service on December 31, 1984, and will not be available for placing in service at an earlier date. Z makes payments to X of $135,000 on December 31, 1983, and $110,000 on December 31, 1984.
(ii) The investment credit allowed Y in 1980 and 1981 for qualified progress expenditures is subject to recapture under section 47(a)(3) and Y may not treat its $85,000 payment in 1982 as a qualified progress expenditure.
(iii) For purposes of determining if the airplane is qualified progress expenditure property with respect to Z, the normal construction period for the property for Z begins on December 31, 1982, the date of transfer. Since the remaining construction period is two years, the property is progress expenditure property if it otherwise qualifies in Z's hands.
(iv) Only $305,000 of the $340,000 payment to Y can qualify as a qualified progress expenditure, because only that amount is attributable to construction costs paid by Y and does not exceed the sum of the amount by which Y increased qualified investment in 1980 and 1981 for qualified progress expenditures ($220,000) and the amount that Y would have treated as a qualified progress expenditure in 1982 ($85,000).
(v) Assume that Z cannot establish that progress in construction has been completed more rapidly than ratably. If Z makes an election under section 46(d) for 1982, then for purposes of applying the percentage of completion limitation, Z's normal construction period is considered to begin on January 1, 1980. Progress is presumed to occur ratably over the 5-year construction period, which is 20 percent in each year.
(vi) For 1982, Z may treat the full $305,000 as a qualified progress expenditure because it is less than the percentage of completion limitation, $330,000 ($110,000 a year for 1980, 1981, and 1982).
(vii) For 1983, Z may treat the entire $135,000 payment as a qualified progress expenditure, since it does not exceed the percentage of completion limitation for that year, $135,000 ($110,000 plus the $25,000 excess from 1982).
(viii) For Z's taxable year ending December 31, 1984, no qualified progress expenditures may be taken into account because the property is placed in service during that year.
