    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.172-5  Taxable income which is subtracted from net operating 
loss to determine carryback or carryover.

    (a) Taxable year subject to the Internal Revenue Code of 1954. The 
taxable income for any taxable year subject to the Internal Revenue Code 
of 1954 which is subtracted from the net operating loss for any other 
taxable year to determine the portion of such net operating loss which 
is a carryback or a carryover to a particular taxable year is computed 
with the modifications prescribed in this paragraph. These modifications 
shall be made independently of, and without reference to, the 
modifications required by Sec. Sec. 1.172-2(a) and 1.172-3(a) for 
purposes of computing the net operating loss itself.
    (1) Modifications applicable to unincorporated taxpayers only. In 
the case of a taxpayer other than a corporation, in computing taxable 
income and adjusted gross income:
    (i) No deduction shall be allowed under section 151 for the personal 
exemptions (or under any other section which grants a deduction in lieu 
of the deductions allowed by section 151) and under section 1202 in 
respect of the net long-term capital gain.
    (ii) The amount deductible on account of losses from sales or 
exchanges of capital assets shall not exceed the amount includible on 
account of gains from sales or exchanges of capital assets.
    (2) Modifications applicable to all taxpayers. In the case either of 
a corporation or of a taxpayer other than a corporation:

    (i) Net operating loss deduction. The net operating loss deduction 
for such taxable year shall be computed by taking into account only such 
net operating losses otherwise allowable as carrybacks or carryovers to 
such taxable year as were sustained in taxable years preceding the 
taxable year in which the taxpayer sustained the net operating loss from 
which the taxable income is to be deducted. Thus, for such purposes, the 
net operating loss for the loss year or any taxable year thereafter 
shall not be taken into account.

    Example. The taxpayer's income tax returns are made on the basis of 
the calendar year. In computing the net operating loss deduction for 
1954, the taxpayer has a carryover from 1952 of $9,000, a carryover from 
1953 of $6,000, a carryback from 1955 of $18,000, and a carryback from 
1956 of $10,000, or an aggregate of $43,000 in carryovers and 
carrybacks. Thus, the net operating loss deduction for 1954, for 
purposes of determining the tax liability for 1954, is $43,000. However, 
in computing the taxable income for 1954 which is subtracted from the 
net operating loss for 1955 for the purpose of determining the portion 
of such loss which may be carried over to subsequent taxable years, the 
net operating loss deduction for 1954 is $15,000, that is, the aggregate 
of the $9,000 carryover from 1952 and the $6,000 carryover from 1953. In 
computing the net operating loss deduction for such purpose, the $18,000 
carryback from 1955 and the $10,000 carryback from 1956 are disregarded. 
In computing the taxable income for 1954, however, which is subtracted 
from the net operating loss for 1956 for the purpose of determining the 
portion of such loss which may be carried over to subsequent taxable 
years, the net operating loss deduction for 1954 is $33,000, that is, 
the aggregate of the $9,000 carryover from 1952, the $6,000 carryover 
from 1953, and the $18,000 carryback from 1955. In computing the net 
operating loss deduction for such purpose, the $10,000 carryback from 
1956 is disregarded.

    (ii) Recomputation of percentage limitations. Unless otherwise 
specifically provided in this subchapter, any deduction which is limited 
in amount to a percentage of the taxpayer's taxable income or adjusted 
gross income shall be recomputed upon the basis of the taxable income or 
adjusted gross income, as the case may be, determined with the 
modifications prescribed in this paragraph. Thus, in the case of an 
individual the deduction for medical expenses would be recomputed after 
making all the modifications prescribed in this paragraph, whereas the 
deduction for charitable contributions would be determined without 
regard to any net operating loss carryback but with regard to any other 
modifications so prescribed. See, however, the regulations under 
paragraph (g) of Sec. 1.170-2 (relating to charitable contributions 
carryover of individuals) and paragraph (c) of Sec. 1.170-3 (relating 
to charitable contributions carryover of corporations) for special rules 
regarding charitable contributions in excess of the percentage 
limitations which may be treated as paid in succeeding taxable years.

    Example 1. For the calendar year 1954 the taxpayer, an individual, 
files a return showing taxable income of $4,800, computed as follows:

Salary.......................................................     $5,000
Net long-term capital gain...................................      4,000
                                                              ----------

                                                    .........     $2,200
                                                              ----------
    Taxable income...........................................      4,800



In 1955 the taxpayer undertakes the operation of a trade or business and 
sustains therein a net operating loss of $3,000. Under section 
172(b)(2), it is determined that the entire $3,000 is a carryback to 
1954. In 1956 he sustains a net operating loss of $10,000 in the 
operation of the business. In determining the amount of the carryover of 
the 1956 loss to 1957, the taxable income for 1954 as computed under 
this paragraph is $3,970, determined as follows:

Salary.......................................................     $5,000
Net long-term capital gain...................................      4,000
                                                              ----------
    Total gross income.......................................      9,000

  Deduction for charitable contributions ($2,000        1,800  .........
   actually paid but allowable only to extent not
   in excess of 20 percent of adjusted gross
   income determined with all the modifications
   prescribed in this paragraph other than the net
   operating loss carryback)......................
                                                   -----------
                                                    .........      2,030

    Taxable income...........................................      3,970


    Example 2. For the calendar year 1959 the taxpayer, an individual, 
files a return showing taxable income of $5,700, computed as follows:

Salary.......................................................     $5,000
Net long-term capital gain...................................      4,000
                                                              ----------
    Total gross income.......................................      9,000
Less: Deduction allowed by section 1202 in respect of net          2,000
 long-term capital gain......................................
                                                              ----------
  Adjusted gross income......................................      7,000
Less:

                                                   -----------
                                                    .........     $1,300
                                                              ----------
    Taxable income................................  .........      5,700



In 1960 the taxpayer undertakes the operation of a trade or business and 
sustains therein a net operating loss of $4,700. In 1961 he sustains a 
net operating loss of $10,000 in the operation of the business. Under 
section 172(b)(2), it is determined that the entire amount of each loss, 
$4,700 and $10,000, is a carryback to 1959. In determining the amount of 
the carryover of the 1961 loss to 1962, the taxable income for 1959 as 
computed under this paragraph is $3,870, determined as follows:

Salary.......................................................     $5,000
Net long-term capital gain...................................      4,000
                                                              ----------
    Total gross income.......................................      9,000
Less: Deduction for carryback of 1960 net operating loss.....      4,700
                                                              ----------
    Adjusted gross income....................................      4,300
Less: Standard deduction.....................................        430
                                                              ----------
    Taxable income...........................................      3,870


    (iii) Minimum limitation. The taxable income, as modified under this 
paragraph, shall in no case be considered less than zero.
    (3) Electing small business corporations. For special rule 
applicable to corporations which were electing small business 
corporations under Subchapter S (section 1361 and following), Chapter 1 
of the Code, during one or more of the taxable years described in 
section 172(b)(1), see paragraph (f) of Sec. 1.172-1.
    (4) Qualified real estate investment trust. Where a net operating 
loss is carried over to a qualified taxable year (as defined in Sec. 
1.172-10(b)) ending after October 4, 1976, the real estate investment 
trust taxable income (as defined in section 857(b)(2)) shall be used as 
the ``taxable income'' for that taxable year to determine, under section 
172(b)(2), the balance of the net operating loss available as a 
carryover to a subsequent taxable year. The real estate investment trust 
taxable income, however, is computed by applying the rules applicable to 
corporations in paragraph (a)(2) of this section. Thus, in computing 
real estate investment trust taxable income for purposes of section 
172(b)(2), the net operating loss deduction for the taxable year shall 
be computed in accordance with paragraph (a)(2)(i) of this section. The 
principles of this subparagraph may be illustrated by the following 
examples:

    Example 1. Corporation X, a calendar year taxpayer, is formed on 
January 1, 1977. X incurs a net operating loss of $100,000 for its 
taxable year 1977, which under section 172(b)(2), is a carryover to 
1978. For 1978 X is a qualified real estate investment trust (as defined 
in Sec. 1.172-10(b)) and has real estate investment trust taxable 
income (determined without regard to the deduction for dividends paid or 
the net operating loss deduction) of $150,000, all of which consists of 
ordinary income. X pays dividends in 1978 totaling $120,000 that qualify 
for the deduction for dividends paid under section 857(b)(2)(B). The 
portion of the 1977 net operating loss available as a carryover to 1979 
and subsequent years is $70,000 (i.e., the excess of the amount of the 
net operating loss ($100,000) over the amount of the real estate 
investment trust taxable income for 1978 ($30,000), determined by taking 
into account the deduction for dividends paid allowable under section 
857(b)(2)(B) and without taking into account the net operating loss of 
1977).
    Example 2. (i) Assume the same facts as in Example 1, except that 
the $150,000 of real estate investment trust taxable income (determined 
without the net operating loss deduction or the dividends paid 
deduction) consists of $80,000 of ordinary income and $70,000 of net 
capital gain. The amount of capital gain dividends which may be paid for 
1978 is

[[Page 182]]

limited to $50,000, that is, the amount of the real estate investment 
trust taxable income for 1978, determined by taking into account the net 
operating loss deduction for the taxable year, but not the deduction for 
dividends paid ($150,000 minus $100,000). See Sec. 1.857-6(e)(1)(ii).
    (ii) X designated $50,000 of the $120,000 of dividends paid as 
capital gains dividends (as defined in section 857(b)(3)(C) and Sec. 
1.857-6(e)). Thus, $70,000 is an ordinary dividend. Since both ordinary 
dividends and capital gains dividends are taken into account in 
computing the deduction for dividends paid under section 857(b)(2)(B), 
the result will be the same as in Example 1; that is, the portion of the 
1977 net operating loss available as a carryover to 1979 and subsequent 
years is $70,000.
