                       TITLE 26--INTERNAL REVENUE
 
    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.270-1  Limitation on deductions allowable to individuals in 
certain cases.

    (a) Recomputation of taxable income. (1) Under certain 
circumstances, section 270 limits the deductions (other than certain 
deductions described in subsection (b) thereof) attributable to a trade 
or business carried on by an individual which are otherwise allowable to 
such individual under the provisions of chapter 1 of the Code or the 
corresponding provisions of prior revenue laws. If, in each of five 
consecutive taxable years (including at least one taxable year beginning 
after December 31, 1953, and ending after August 16, 1954), the 
deductions attributable to a trade or business carried on by an 
individual (other than the specially treated deductions described in 
paragraph (b) of this section) exceed the gross income derived from such 
trade or business by more than $50,000, the taxable income computed 
under section 63 (or the net income computed under the corresponding 
provisions of prior revenue

[[Page 594]]

laws) of such individual shall be recomputed for each of such taxable 
years.
    (2) In recomputing the taxable income (or the net income, in the 
case of taxable years which are otherwise subject to the Internal 
Revenue Code of 1939) for each of the five taxable years, the deductions 
(other than the specially treated deductions described in paragraph (b) 
of this section with the exception of the net operating loss deduction) 
attributable to the trade or business carried on by the individual shall 
be allowed only to the extent of (i) the gross income derived from such 
trade or business, plus (ii) $50,000. The specially treated deductions 
described in paragraph (b) of this section (other than the net operating 
loss deduction) shall each be allowed in full. The net operating loss 
deduction, to the extent attributable to such trade or business, shall 
be disallowed in its entirety. Thus, a carryover or a carryback of a net 
operating loss so attributable, either from a year within the period of 
five consecutive taxable years or from a taxable year outside of such 
period, shall be ignored in making the recomputation of taxable income 
or net income, as the case may be.
    (3) The limitations on deductions provided by section 270 are also 
applicable in determining under section 172, or the corresponding 
provisions of prior revenue laws, the amount of any net operating loss 
carryover or carryback from any year which falls within the provisions 
of section 270 to any year which does not fall within such provisions. 
Also, in determining under section 172, or the corresponding provisions 
of prior revenue laws, the amount of any net operating loss carryover 
from a year which falls within the provisions of section 270 to a year 
which does not fall within such provisions, the amount of net operating 
loss is to be reduced by the taxable income or net income, as the case 
may be (computed as provided in Sec. 1.172-5, or 26 CFR (1939) 39.122-
4(c) (Regulations 118), as the case may be and, in the case of any 
taxable year which falls within the provisions of section 270, 
determined after the application of section 270), of any taxable year 
preceding or succeeding the taxable year of the net operating loss to 
which such loss must first be carried back or carried over under the 
provisions of section 172(b), or the corresponding provisions of prior 
revenue laws, even though the net operating loss deduction is not an 
allowable deduction for such preceding or succeeding taxable year.
    (4) If an individual carries on several trades or businesses, the 
deductions attributable to such trades or businesses and the gross 
income derived therefrom shall not be aggregated in determining whether 
the deductions (other than the specially treated deductions) exceed the 
gross income derived from such trades or businesses by more than $50,000 
in any taxable year. For the purposes of section 270, each trade or 
business shall be considered separately. However, where a particular 
business of an individual is conducted in one or more forms such as a 
partnership, joint venture, or individual proprietorship, the 
individual's share of the profits and losses from each business unit 
must be aggregated to determine the applicability of section 270. See 
paragraphs (a)(8)(ii) and (b) of Sec. 1.702-1, relating to 
applicability of section 270 to a partner. Where it is established that 
for tax purposes a husband and wife are partners in the same trade or 
business or that each is participating independently of the other in the 
same trade or business with his and her own money, the husband's gross 
income and deductions from that trade or business shall be considered 
separately from the wife's gross income and deductions from that trade 
or business even though they file a joint return. Where a taxpayer is 
engaged in a trade or business in a community property State under 
circumstances such that the income therefrom is considered to be 
community income, the taxpayer and his spouse are treated for purposes 
of section 270 as two individuals engaged separately in the same trade 
or business and the gross income and deductions attributable to the 
trade or business are allocated one-half to the taxpayer and one-half to 
the spouse. Where several business activities emanate from a single 
commodity, such as oil or gas or a tract of land, it does not 
necessarily follow that such activities are one business for the 
purposes of section 270. However, in order to be

[[Page 595]]

treated separately, it must be established that such business activities 
are actually conducted separately and are not closely interrelated with 
each other. For the purposes of section 270, the trade or business 
carried on by an individual must be the same in each of the five 
consecutive years in which the deductions (other than the specially 
treated deductions) exceed the gross income derived from such trade or 
business by more than $50,000.
    (5) For the purposes of section 270, a taxable year may be part of 
two or more periods of five consecutive taxable years. Thus, if the 
deductions (other than the specially treated deductions) attributable to 
a trade or business carried on by an individual exceed the gross income 
therefrom by more than $50,000 for each of six consecutive taxable 
years, the fifth year of such six consecutive taxable years shall be 
considered to be a part both of a five-year period beginning with the 
first and ending with the fifth taxable year and of a five-year period 
beginning with the second and ending with the sixth taxable year.
    (6) For the purposes of section 270, a short taxable year required 
to effect a change in accounting period constitutes a taxable year. In 
determining the applicability of section 270 in the case of a short 
taxable year, items of income and deduction are not annualized.
    (b) Specially treated deductions. (1) For the purposes of section 
270 and paragraph (a) of this section, the specially treated deductions 
are:
    (i) Taxes,
    (ii) Interest,
    (iii) Casualty and abandonment losses connected with a trade or 
business deductible under section 165(c)(1) or the corresponding 
provisions of prior revenue laws,
    (iv) Losses and expenses of the trade or business of farming which 
are directly attributable to drought,
    (v) The net operating loss deduction allowed by section 172, or the 
corresponding provisions of prior revenue laws, and
    (vi) Expenditures as to which a taxpayer is given the option, under 
law or regulations, either (a) to deduct as expenses when incurred, or 
(b) to defer or capitalize.
    (2) For the purpose of subparagraph (1)(iv) of this paragraph, an 
individual is engaged in the ``trade or business of farming'' if he 
cultivates, operates, or manages a farm for gain or profit, either as 
owner or tenant. An individual who receives a rental (either in cash or 
in kind) which is based upon farm production is engaged in the trade or 
business of farming. However, an individual who receives a fixed rental 
(without reference to production) is engaged in the trade or business of 
farming only if he participates to a material extent in the operation or 
management of the farm. An individual engaged in forestry or the growing 
of timber is not thereby engaged in the trade or business of farming. An 
individual cultivating or operating a farm for recreation or pleasure 
rather than a profit is not engaged in the trade or business of farming. 
The term farm is used in its ordinarily accepted sense and includes 
stock, dairy, poultry, fruit, crop, and truck farms, and also 
plantations, ranches, ranges, and orchards. An individual is engaged in 
the trade or business of farming if he is a member of a partnership 
engaged in the trade or business of farming.
    (3) In order for losses and expenses of the trade or business of 
farming to qualify as specially treated deductions under subparagraph 
(1)(iv) of this paragraph such losses and expenses must be directly 
attributable to drought conditions and not to other causes such as 
faulty management or unfavorable market conditions. In general, the 
following are the types of losses and expenses which, if otherwise 
deductible, may qualify as specially treated deductions under 
subparagraph (1)(iv) of this paragraph:
    (i) Losses for damages to or destruction of property as a result of 
drought conditions, if such property is used in the trade or business of 
farming or is purchased for resale in the trade or business of farming;
    (ii) Expenses directly related to raising crops or livestock which 
are destroyed or damaged by drought. Included in this category are, for 
example, payments for labor, fertilizer, and

[[Page 596]]

feed used in raising such crops or livestock. If such crops or livestock 
to which the expenditures relate are only partially destroyed or damaged 
by drought then only a proportionate part of the expenditures is 
regarded as specially treated deductions; and
    (iii) Expenses which would not have been incurred in the absence of 
drought conditions, such as expenses for procuring pasture or additional 
supplies of water or feed.
    (4) The expenditures referred to in subparagraph (1)(vi) of this 
paragraph include, but are not limited to, intangible drilling and 
development costs in the case of oil and gas wells as provided in 
section 263(c) and the regulations thereunder, and expenditures for the 
development of a mine or other natural deposit (other than an oil or gas 
well) as provided in section 616 and the regulations thereunder.
    (5) The provisions of section 270(b) do not operate to make an 
expenditure a deductible item if it is not otherwise deductible under 
the law applicable to the particular year in which it was incurred. 
Thus, for example, if it is necessary, pursuant to the provisions of 
section 270, to recompute the taxable or net income of an individual for 
the taxable years 1950 through 1954, the individual in making the 
recomputation may not deduct expenditures paid or incurred in the years 
1950 through 1953 which must be capitalized under the law applicable to 
those years, even though the expenditures are deductible under the Code.
    (c) Applicability to taxable years otherwise subject to the Internal 
Revenue Code of 1939. The net income of a taxable year otherwise subject 
to the Internal Revenue Code of 1939 shall be recomputed pursuant to 
section 270 if (i) such taxable year is included in a period of five 
consecutive taxable years which includes at least one taxable year 
beginning after December 31, 1953, and ending after August 16, 1954, and 
(ii) the deductions (other than the specially treated deductions 
specified in section 270(b)) for each taxable year in such five-year 
period exceed the $50,000 limitation specified in section 270. As 
described in paragraph (a)(5) of this section, a taxable year may be 
part of two or more periods of five consecutive taxable years, one 
meeting the requirements for recomputation pursuant to section 130 of 
the Internal Revenue Code of 1939 and the other meeting the requirements 
for recomputation pursuant to section 270 of the Internal Revenue Code 
of 1954, then the recomputation for such taxable year shall be made 
pursuant to section 270. For example, if a calendar year taxpayer 
sustains a loss from a trade or business for each of the years 1949 
through 1954, the years 1950, 1951, 1952, and 1953 may be a part of two 
such periods of five consecutive taxable years. If, however, a taxable 
year is part of a period of five consecutive taxable years which meets 
the requirements for recomputation pursuant to section 130 of the 
Internal Revenue Code of 1939, but is not part of a period which meets 
the requirements for recomputation, pursuant to section 270, then a 
recomputation of net income for such taxable year must be made pursuant 
to section 130.
    (d) Redetermination of tax. The tax imposed by Chapter 1 of the 
Code, or by the corresponding provisions of prior revenue laws, for each 
of the five consecutive taxable years specified in paragraph (a) of this 
section shall be redetermined upon the basis of the taxable income or 
net income of the individual, as the case may be, recomputed in the 
manner described in paragraph (a) of this section. If the assessment of 
a deficiency is prevented (except for the provisions of Part II (section 
1311 and following), Subchapter Q, Chapter 1 of the Code, relating to 
the effect of limitations and other provisions in income tax cases) by 
the operation of any provision of law (e.g., sections 6501 and 6502, or 
the corresponding provisions of prior revenue laws, relating to the 
period of limitations upon assessment and collection) except section 
7122, or the corresponding provisions of prior revenue laws, relating to 
compromises, or by any rule of law (e.g., res judicata), then the excess 
of the tax for such year as recomputed over the tax previously 
determined for such year shall be considered a deficiency for the 
purposes of section 270. The term tax previously determined shall have 
the same meaning as that assigned to such term by section 1314(a). See 
Sec. 1.1314 (a)-1.

[[Page 597]]

    (e) Assessment of tax. Any amount determined as a deficiency in the 
manner described in paragraph (d) of this section in respect of any 
taxable year of the five consecutive taxable years specified in 
paragraph (a) of this section may be assessed and collected as if on the 
date of the expiration of the period of limitation for the assessment of 
a deficiency for the fifth taxable year of such five consecutive taxable 
years, one year remained before the expiration of the period of 
limitation upon assessment for the taxable year in respect of which the 
deficiency is determined. If the taxable year is one in respect of which 
an assessment could be made without regard to section 270, the amount of 
the actual deficiency as defined in section 6211(a) (whether it is 
greater than, equal to, or less than the deficiency determined under 
section 270(c)) shall be assessed and collected. However, if the 
assessment of a deficiency for such taxable year would be prevented by 
any provision of law (e.g., the period of limitation upon the assessment 
of tax) except section 7122, or the corresponding provision of prior 
revenue laws, relating to compromises, or by the operation of any rule 
of law (e.g., res judicata), then the excess of the tax recomputed as 
described in paragraph (d) of this section over the tax previously 
determined may be assessed and collected even though in fact there is no 
actual deficiency, as defined in section 6211(a), in respect of the 
given taxable year.
    (f) Effective date; cross reference. The provisions of section 270 
and this section apply to taxable years beginning before January 1, 
1970. Thus, for instance, if the taxpayer had a profit of $2,000 
attributable to a trade or business in 1965, section 270 and this 
section would not apply to the taxable years 1966 through 1970, even 
though he had losses of more than $50,000 in each of the 5 years ending 
with 1970. For provisions relating to activities not engaged in for 
profit applicable to taxable years beginning after December 31, 1969, 
see section 183 and the regulations thereunder.
