Sec. 1.172-7  Joint return by husband and wife.

    (a) In general. This section prescribes additional rules for 
computing the net operating loss carrybacks and carryovers of a husband 
and wife making a joint return for one or more of the taxable years 
involved in the computation of the net operating loss deduction.
    (b) From separate to joint return. If a husband and wife, making a 
joint return for any taxable year, did not make a joint return for any 
of the taxable years involved in the computation of a net operating loss 
carryover or a net operating loss carryback to the taxable year for 
which the joint return is made, such separate net operating loss 
carryover or separate net operating loss carryback is a joint net 
operating loss carryover or joint net operating loss carryback to such 
taxable year.
    (c) Continuous use of joint return. If a husband and wife making a 
joint return for a taxable year made a joint return for each of the 
taxable years involved in the computation of a net operating loss 
carryover or net operating loss carryback to such taxable year, the 
joint net operating loss carryover or joint net operating loss carryback 
to such taxable year is computed in the same manner as the net operating 
loss carryover or net operating loss carryback of an individual under 
Sec. 1.172-4 but upon the basis of the joint net operating losses and 
the combined taxable income of both spouses.
    (d) From joint to separate return. If a husband and wife making 
separate returns for a taxable year made a joint return for any, or all, 
of the taxable years involved in the computation of a net operating loss 
carryover or net operating loss carryback to such taxable year, the 
separate net operating loss carryover or separate net operating loss 
carryback of each spouse to the taxable year is computed in the manner 
set forth in Sec. 1.172-4 but with the following modifications:
    (1) Net operating loss. The net operating loss of each spouse for a 
taxable year for which a joint return was made shall be deemed to be 
that portion of the joint net operating loss (computed in accordance 
with paragraph (d) of Sec. 1.172-3) which is attributable to the gross 
income and deductions of such spouse, gross income and deductions being 
taken into account to the same extent that they are taken into account 
in computing the joint net operating loss.
    (2) Taxable income to be subtracted--(i) Net operating loss of other 
spouse. The taxable income of a particular spouse for any taxable year 
which is subtracted from the net operating loss of such spouse for 
another taxable year in order to determine the amount of such loss which 
may be carried back or carried over to still another taxable year is 
deemed to be, in a case in which such

[[Page 186]]

taxable income was reported in a joint return, the sum of the following:
    (a) That portion of the combined taxable income of both spouses for 
such year for which the joint return was made which is attributable to 
the gross income and deductions of the particular spouse, gross income 
and deductions being taken into account to the same extent that they are 
taken into account in computing such combined taxable income, and
    (b) That portion of such combined taxable income which is 
attributable to the other spouse; but, if such other spouse sustained a 
net operating loss in a taxable year beginning on the same date as the 
taxable year in which the particular spouse sustained the net operating 
loss from which the taxable income is subtracted, then such portion 
shall first be reduced by such net operating loss of such other spouse.
    (ii) Modifications. For purposes of this subparagraph, the combined 
taxable income shall be computed as though the combined income and 
deductions of both spouses were those of one individual. The provisions 
of Sec. 1.172-5 shall apply in computing the combined taxable income 
for such purposes except that the net operating loss deduction shall be 
determined without taking into account any separate net operating loss 
of either spouse, or any joint net operating loss of both spouses, which 
was sustained in a taxable year beginning on or after the date of the 
beginning of the taxable year in which the particular spouse sustained 
the net operating loss from which the taxable income is subtracted.
    (e) Recurrent use of joint return. If a husband and wife making a 
joint return for any taxable year made a joint return for one or more, 
but not all, of the taxable years involved in the computation of a net 
operating loss carryover or net operating loss carryback to such taxable 
year, such net operating loss carryover or net operating loss carryback 
to the taxable year is computed in the manner set forth in paragraph (d) 
of this section. Such net operating loss carryover or net operating loss 
carryback is considered a joint net operating loss carryover or joint 
net operating loss carryback to such taxable year.
    (f) Joint carryovers and carrybacks. The joint net operating loss 
carryovers and the joint net operating loss carrybacks to any taxable 
year for which a joint return is made are all the net operating loss 
carryovers and net operating loss carrybacks of both spouses to such 
taxable year. For example, a husband and wife file a joint return for 
the calendar year 1956, having a joint taxable income for such year. The 
wife filed a separate return for the calendar years 1954 and 1955, in 
which years she sustained net operating losses. The husband filed 
separate returns for his fiscal year ending June 30, 1955, and, having 
received permission to change his accounting period to a calendar year 
basis, for the 6-month period ending December 31, 1955. The husband 
sustained net operating losses in both such taxable years. Since the 
husband and wife did not file a joint return for any taxable year 
involved in the computation of the net operating loss carryovers to 1956 
from 1954 and 1955, the joint net operating loss carryovers to 1956 are 
the separate net operating loss carryovers of the wife from the calendar 
years 1954 and 1955 and the separate net operating loss carryovers of 
the husband from the fiscal year ending June 30, 1955, and from the 
short taxable year ending December 31, 1955. If the husband and wife 
also file joint returns for the calendar years 1957, 1958, and 1959, 
having joint taxable income in 1957 and 1958 and a joint net operating 
loss in 1959, the joint net operating loss carrybacks to 1956, 1957, and 
1958 from 1959 are computed on the basis of the joint net operating loss 
for 1959, since separate returns were not made for any taxable year 
involved in the computation of such carrybacks.
    (g) Illustration of principles. In the following examples, which 
illustrate the application of this section, it is assumed that there are 
no items of adjustment under section 172(b)(2)(A) and that the taxable 
income or loss in each case is the taxable income or loss determined 
without any net operating loss deduction. The taxpayers in each example, 
H, a husband, and W, his wife, report their income on the calendar-year 
basis.


[[Page 187]]


    Example 1. H and W filed joint returns for 1954 and 1955. They 
sustained a joint net operating loss of $1,000 for 1954 and a joint net 
operating loss of $2,000 for 1955. For 1954 the deductions of H exceeded 
his gross income by $700, and the deductions of W exceeded her gross 
income by $300, the total of such amounts being $1,000. Therefore, $700 
of the $1,000 joint net operating loss for 1954 is considered the net 
operating loss of H for 1954, and $300 of such joint net operating loss 
is considered the net operating loss of W for 1954. For 1955 the gross 
income of H exceeded his deductions, so that his separate taxable income 
would be $1,500, and the deductions of W exceeded her gross income by 
$3,500. Therefore, all of the $2,000 joint net operating loss for 1955 
is considered the separate net operating loss of W for 1955.
    Example 2. (i) H and W filed joint returns for 1954 and 1956, and 
separate returns for 1955 and 1957. For the years 1954, 1955, 1956, and 
1957 they had taxable incomes and net operating losses as follows, 
losses being indicated in parentheses:

------------------------------------------------------------------------
                                    1954      1955      1956      1957
------------------------------------------------------------------------
H...............................  ($5,000)  ($2,500)    $6,500  ($4,000)
W...............................   (3,000)     2,000     3,000   (1,500)
                                 ---------------------------------------
  Total.........................   (8,000)  ........     9,500  ........
------------------------------------------------------------------------

    (ii) The net operating loss carryover of H from 1957 to 1958 is 
$4,000, that is, his $4,000 net operating loss for 1957 which is not 
reduced by any part of the taxable income for 1956, since none of such 
taxable income is attributable to H and the portion attributable to W is 
entirely offset by her separate net operating loss for her taxable year 
1957, which taxable year begins on the same date as H's taxable year 
1957. H's $4,000 net operating loss for 1957 likewise is not reduced by 
reference to 1955 since H sustained a loss in 1955. The $0 taxable 
income for 1956 which reduces H's net operating loss for 1957 is 
computed as follows:
    (iii) The combined taxable income of $9,500 for 1956 is reduced to 
$1,000 by the net operating loss deduction for such year of $8,500. This 
net operating loss deduction is computed without taking into account any 
net operating loss of either H or W sustained in a taxable year 
beginning on or after January 1, 1957, the date of the beginning of the 
taxable year in which H sustained the net operating loss from which the 
taxable income is subtracted. This $8,500 is composed of H's carryovers 
of $5,000 from 1954 and $2,500 from 1955, and of W's carryover of $1,000 
from 1954 (the excess of W's $3,000 loss for 1954 over her $2,000 income 
for 1955). None of the $1,000 combined taxable income for 1956 (computed 
with the net operating loss deduction described above) is attributable 
to H since it is caused by W's income (computed after deducting her 
separate carryover) offsetting H's loss (computed by deducting from his 
income his separate carryovers). No part of the $1,000 combined taxable 
income for 1956 which is attributable to W is used to reduce H's net 
operating loss for 1957 since such taxable income attributable to W must 
first be reduced by W's $1,500 net operating loss for 1957, her taxable 
year beginning on the same date as the taxable year of H in which he 
sustained the net operating loss from which the taxable income is 
subtracted.
    (iv) The net operating loss carryover of W from 1957 to 1958 is 
$500, her $1,500 loss reduced by the sum of her $0 taxable income for 
1955 (computed by taking into account her $3,000 carryover from 1954) 
and her $1,000 taxable income for 1956, that is, the portion of the 
combined taxable income for 1956 which is attributable to her.
    Example 3. (i) Assume the same facts as in Example 2 except that for 
1957 the net operating loss of W is $200 instead of $1,500.
    (ii) The net operating loss carryover of H from 1957 to 1958 is 
$3,200, that is, his $4,000 net operating loss for 1957 reduced by the 
sum of his $0 taxable income for 1955 (a year in which he sustained a 
loss) and his $800 taxable income for 1956. Such $800 is computed as 
follows:
    (iii) The combined taxable income for 1956, computed with the net 
operating loss deduction in the manner described in Example 2, remains 
$1,000, no part of which is attributable to H. To the $0 taxable income 
attributable to H for 1956 there is added $800, the excess of the $1,000 
taxable income for such year attributable to W over her $200 net 
operating loss sustained in 1957, a taxable year beginning on the same 
date as the taxable year of H in which he sustained the $4,000 net 
operating loss from which the taxable income is subtracted.
    (iv) W has no net operating loss carryover from 1957 to 1958 since 
her net operating loss of $200 for 1957 does not exceed the $1,000 
taxable income for 1956 attributable to her.
    Example 4. (i) Assume the same facts as in Example 2, except that W 
changes her accounting period in 1957 to a fiscal year ending on January 
31, and has neither income nor losses for the taxable year January 1, 
1957, to January 31, 1957, or for the fiscal year February 1, 1957, to 
January 31, 1958, but has a net operating loss of $200 for the fiscal 
year February 1, 1958, to January 31, 1959.
    (ii) The net operating loss carryover of H from 1957 to 1958 is 
$3,000, that is, his net operating loss of $4,000 for 1957 reduced by 
the sum of his $0 taxable income for 1955 (a year in which he sustained 
a loss) and his $1,000 taxable income for 1956. Such $1,000 is computed 
as follows:
    (iii) The combined taxable income for 1956, computed with the net 
operating loss deduction in the manner described in Example 2,

[[Page 188]]

remains $1,000, no part of which is attributable to H. To the $0 taxable 
income attributable to H for 1956 there is added the $1,000 taxable 
income attributable to W for such year. The taxable income attributable 
to W is not reduced by any amount since she does not have a net 
operating loss for her taxable year beginning on January 1, 1957, the 
date of the beginning of the taxable year of H in which he sustained the 
$4,000 net operating loss from which his taxable income is subtracted.
    (iv) The net operating loss carryover of W from the fiscal year 
beginning February 1, 1958, to her next fiscal year is $200, that is, 
her net operating loss of $200 for the fiscal year beginning February 1, 
1958, reduced by the sum of her $0 taxable income for 1956, her $0 
taxable income for the taxable year January 1, 1957, to January 31, 1957 
(a year in which she had neither income nor loss), and her $0 taxable 
income for the fiscal year February 1, 1957, to January 31, 1958 (also a 
year in which she had neither income nor loss). The $0 taxable income 
for 1956 is computed as follows:
    (v) The combined taxable income of $9,500 for 1956 is reduced to $0 
amount by the net operating loss deduction for such year of $12,500. 
This net operating loss deduction is computed by taking into account the 
net operating loss of H for 1957 since it was sustained in a taxable 
year beginning before February 1, 1958, the date of the beginning of the 
taxable year of W in which she sustained the $200 net operating loss 
from which her taxable income is subtracted. This $12,500 is composed of 
H's carryovers of $5,000 from 1954 and $2,500 from 1955 and of his 
carryback of $4,000 from 1957, plus W's carryover of $1,000 from 1954 
(the excess of W's $3,000 loss for 1954 over her $2,000 income for 
1955). Since there is no combined taxable income for 1956, there is no 
taxable income attributable to W for such year.
