PART 1--INCOME TAXES--Table of Contents
 
Sec. 1.57-4  Limitation on amounts treated as items of tax preference for taxable years beginning before January 1, 1976.

    (a) In general. If in any taxable year beginning before January 1, 
1976, a taxpayer has deductions in excess of gross income and all or a 
part of any item of tax preference described in Sec. 1.57-1 results in 
no tax benefit due to modifications required under section 172(c) or 
section 172(b)(2) in computing the amount of the net operating loss or 
the net operating loss to be carried to a succeeding taxable year, then, 
for purposes of section 56(a)(1), the sum of the items of tax preference 
determined under section 57(a) (and Sec. 1.57-1) is to be limited as 
provided in paragraph (b) of this section.
    (b) Limitation. The sum of the items of tax preference, for purposes 
of section 56(a)(1) and Sec. 1.56A-1(a), is limited to an amount 
determined under subparagraphs (1) and (2) of this paragraph.
    (1) Loss year. If the taxpayer has no taxable income for the taxable 
year without regard to the net operating loss deduction, the amount of 
the limitation is equal to--
    (i) In cases where the taxpayer does not have a net operating loss 
for the taxable year, the amount of the recomputed income (as defined in 
paragraph (c) of this section) or
    (ii) In cases where the taxpayer has a net operating loss for the 
taxable year, the amount of the net operating loss (expressed as a 
positive amount) increased by the recomputed income or decreased by the 
recomputed loss for the taxable year (as defined in paragraph (c) of 
this section,

plus the amount of the taxpayer's stock option item of tax preference 
(as described in Sec. 1.57-1(f)).
    (2) Loss carryover and carryback years. Except in cases to which 
subparagraph (1)(ii) of this paragraph applies, if, in any taxable year 
to which a net operating loss is carried, a capital gains deduction is 
disallowed under section 172(b)(2) in computing the amount of such net 
operating loss which may be carried to succeeding taxable years, the 
amount of the limitation is equal to the amount, if any, by which the 
sum of the items of tax preference

[[Page 514]]

(computed with regard to subparagraph (1)(i) of this paragraph) exceeds 
the lesser of--
    (i) The amount by which such loss is reduced because of a 
disallowance of the capital gains deduction in such taxable year, or
    (ii) The capital gains deduction.

The amount determined pursuant to the preceding sentence shall be 
increased by the amount, if any, that such reduction is attributable to 
that portion of such a net operating loss described in section 
56(b)(1)(B) and Sec. 1.56A-2(a)(2) (relating to excess tax preferences).
    (c) Recomputed income or loss. For purposes of this section, the 
phrase ``recomputed income or loss'' means the taxable income or net 
operating loss for the taxable year computed without regard to the 
amounts described in Sec. 1.57-1 except paragraph (i)(2) of that section 
(relating to corporate capital gains) and without regard to the net 
operating loss deduction. For this purpose, the reference to the amounts 
described in Sec. 1.57-1 is a reference to that portion of the deduction 
allowable in computing taxable income under the appropriate section 
equal to the amount which is determined in each paragraph of Sec. 1.57-
1. For example, the amount described in Sec. 1.57-1(h) (relating to 
excess of percentage depletion over basis) is that portion of the 
deduction allowable for depletion under section 611 which is equal to 
the amount determined under Sec. 1.57-1(h). For purposes of this 
paragraph, the amount described in Sec. 1.57-1(i)(1) (relating to 
capital gains) is to be considered as the amount of the deduction 
allowable for the taxable year under section 1202.
    (d) Determination of preferences reduced. When, pursuant to 
paragraph (b)(1) of this section, the sum of the items of tax preference 
(determined without regard to this section) are reduced, such reduction 
is first considered to be from the capital gains item of tax preference 
(described in Sec. 1.57-1(i)(1)) and each item of tax preference 
relating to a deduction disallowed in computing the net operating loss 
pursuant to section 172(d), pro rata. The balance of the reduction, if 
any, is considered to be from the remaining items of tax preference, pro 
rata. For purposes of this subparagraph, deductions not attributable to 
the taxpayer's trade or business which do not relate to items of tax 
preference are considered as being applied in reducing gross income not 
derived from such trade or business before such deductions which do 
relate to items of tax preferences.
    (e) Examples. The principles of this section may be illustrated by 
the following examples in each of which the deduction for the personal 
exemption is disregarded and the taxpayer is an individual who is a 
calendar year taxpayer.

    Example 1. The taxpayer has the following items of income and 
deduction for 1970:

Gross income (all business income)..........................    $120,000
Deductions:
  Nonbusiness deductions....................................      30,000
  Items of tax preference (excess accelerated depreciation        80,000
   on real property held in taxpayer's business)............
  Other business deductions.................................      50,000



Based on the above figures, the taxpayer has a net operating loss of 
$10,000 (business deductions of $130,000 less business income of 
$120,000, the nonbusiness deductions having been disallowed by reason of 
section 172(d)(4)). The limitation on the amount treated as items of tax 
preference is computed as follows:

Tax preferences..............................................    $80,000
                                        ============
Net operating loss................................    $10,000
Recomputed income or loss:
  Gross income.........................   $120,000
  Deductions other than tax preference      80,000
   items...............................
                                        ------------
Recomputed income.................................     40,000
                                        ------------
Sum of net operating loss and recomputed income...     50,000
Stock options preference..........................          0
                                        ------------
Limitation........................................     50,000



[[Page 515]]

Thus, the minimum tax computed under section 56(a) would be 10 percent 
of $20,000 (items of tax preference of $50,000 less the minimum tax 
exemption of $30,000), $1,000 of which would be deferred tax liability 
pursuant to section 56(b).
    Example 2. Assume the same facts as in example 1 except that the 
other business deductions are $130,000, resulting in a net operating 
loss of $90,000. The limitation on the amount treated as items of tax 
preference is computed as follows:

Tax preferences..............................................    $80,000
                                        ============
Net operating loss................................    $90,000
Recomputed income or loss:
  Gross income.........................   $120,000
  Deductions other than tax preference     160,000
   items...............................
                                        ------------
                                          (40,000)
Disallowance of nonbusiness deductions      30,000
 under sec. 172(d).....................
                                        -----------
Recomputed loss...................................     10,000
                                        -----------
Net operating loss less recomputed loss...........     80,000
Stock options preference..........................          0
                                        -----------
Limitation...................................................     80,000



Thus, the minimum tax computed under section 56(a) would be 10 percent 
of $50,000 (items of tax preference of $80,000 less the minimum tax 
exemption of $30,000), all of which will be deferred tax liability 
pursuant to section 56(b).
    Example 3. The taxpayer has the following items of income and 
deduction for 1970:

Gross income (all from business):
Ordinary.....................................................    $50,000
  Net section 1201 gains.....................................    120,000
Deductions:
  Items of tax preference:
    Excess amortization of certified pollution        $45,000
     control facilities...........................
    Capital gains deduction.......................     60,000    105,000
                                                   -----------
  Other business deductions............  .........  .........     75,000



In addition, the taxpayer has a $55,000 item of tax preference resulting 
from qualified stock options. Based on the above figures, the taxpayer 
has no taxable income and no net operating loss as the capital gains 
deduction is disallowed in determining the net operating loss pursuant 
to section 172(d). The limitation on the amount treated as items of tax 
preference is computed as follows:

Tax preferences..............................................   $160,000
                                        ============
Net operating loss................................          0
Recomputed income or loss:
  Gross income.........................   $170,000
  Deductions other than tax preference      75,000
   items...............................
                                        ------------
Recomputed income.................................    $95,000
  Plus: Stock options preference..................     55,000
                                        -----------
Limitation...................................................    150,000


Thus, the minimum tax computed under section 56 would be 10 percent of 
$120,000 (items of tax preference of $150,000 less the minimum tax 
exemption of $30,000).
    Example 4. Assume the same facts as in example (3) except that the 
taxpayer has a net operating loss carryover from 1969 of $80,000. The 
taxpayer has $160,000 of tax preferences which are limited to $150,000 
pursuant to Sec. 1.57-4(b)(1). In order to determine the amount of the 
1969 net operating loss which remains as a carryover to 1971, the 1970 
taxable income is redetermined in accordance with section 172(b)(2) and 
the regulations thereunder, as follows:

Gross income--1970..............................    $170,000
Deductions:
  Capital gains deduction disallowed business       $120,000     120,000
   deductions...................................
                                                 -----------------------
    Taxable income for section 172(b)(2)....................      50,000



[[Page 516]]


Thus, the 1969 net operating loss which remains as a carryover to 1971 
is $30,000. Pursuant to paragraph (b)(2) of this section, the limitation 
on the amount treated as items of tax preference is computed as follows:

Items of tax preference computed with regard to Sec.  1.57-     $150,000
 4(b)(1) (per example (3))..................................
Less: Lesser of capital gains deduction ($60,000) or amount       50,000
 of reduction in carryover due to its disallowance ($50,000)
                                                 -------------
    Limitation..............................................     100,000


Thus, the minimum tax computed under section 56 would be 10 percent of 
$70,000 (items of tax preference of $100,000 less the minimum tax 
exemption of $30,000).
    Example 5. The taxpayer has the following items of income and 
deduction for the taxable year 1970 without regard to any net operating 
loss deduction:

Gross income (all from business):
  Ordinary........................................    $50,000
  Net section 1201 gain...........................     40,000
                                                   ------------
                                                                 $90,000
Deductions:
  Capital gains deduction.........................     20,000
  Medical expenses ($4,100 actually paid but            2,000
   allowable only to the extent in excess of 3
   percent of adjusted gross income of $70,000)...
  Other itemized deductions.......................     40,000
                                                   ------------
                                                                  62,000
                                                              ----------
    Taxable income (before net operating loss deduction).....     28,000



In addition, the taxpayer has an item of tax preference of $35,000 
resulting from qualified stock options. In 1973, the taxpayer has a net 
operating loss of $60,000 (no portion of which is attributable to excess 
tax preferences pursuant to Sec. 1.56A-2) which is carried back to 1970 
resulting in no taxable income in 1970. In order to determine the amount 
of the 1973 net operating loss which remains as a carryover to 1971, the 
1970 taxable income is redetermined, in accordance with section 
172(b)(2) and the regulations thereunder, as follows:

Gross income.................................................    $90,000
Deductions:
  Capital gains deduction disallowed..............
  Medical expenses ($4,100 actually paid but           $1,400
   allowable only to the extent in excess of 3
   percent of adjusted gross income of $90,000)...
  Other itemized deductions.......................     40,000
                                                   ------------
                                                                 $41,400
    Taxable income for section 172(b)(2)..........  .........     48,600


    The limitation on the amount treated as items of tax preference is 
computed as follows:

Items of tax preference:
  Capital gains.................................  ..........     $20,000
  Stock options.................................  ..........      35,000
                                                             -----------
                                                                  55,000
Less:
  Lesser of capital gains deduction ($20,000) or amount of      (20,000)
   reduction in carryover due to its disallowance ($20,600).
                                                 -------------
    Limitation..............................................      35,000


Thus, the minimum tax for 1970 under section 56 would be 10 percent of 
$5,000 (items of tax preference of $35,000 less the minimum tax 
exemption of $30,000).
    Example 6. Assume the same facts as in example (5) except that the 
1973 net operating loss was $45,000. In this case, the $20,600 increase 
in the 1970 taxable income as redetermined, results in a decrease of 
$17,000 (i.e., the remaining 1973 net operating loss after an initial 
decrease of $28,000 resulting from the 1970 taxable income before 
redetermination). The limitation on the amount treated as items of tax 
preference is computed as follows:

Items of tax preference computed without regard to this          $55,000
 section....................................................
Less: Lesser of capital gains deduction ($20,000) or amount     (17,000)
 of reduction in carryover due to its disallowance ($17,000)
                                                 -------------
    Limitation..............................................      38,000



Thus, the minimum tax for 1970 under section 56 would be 10 percent of 
$8,000 (items of tax preference of $38,000 less the minimum tax 
exemption of $30,000).
    Example 7. The taxpayer has the following items of income and 
deduction for 1973 without regard to any net operating loss deduction:




Gross income (all from business):
  Ordinary....................................     $100,000
  Net section 1201 gains......................      120,000
                                               --------------
                                                                $220,000
Deductions:
Items of tax preference:
  Excess amortization of certified pollution         45,000
   control facilities.........................
  Capital gains deduction.....................       60,000
                                               -------------
                                                    105,000
  Other business deductions...................       75,000
                                               --------------
                                                                $180,000
    Taxable income (before net operating loss deduction)...       40,000



In 1972, the taxpayer had a net operating loss of $70,000 which is 
carried forward to 1973; $20,000 of this net operating loss is 
attributable to excess tax preferences. In order to determine the amount 
of the 1972 net operating loss which remains as a carryover to

[[Page 517]]

1974, the 1973 taxable income is redetermined, in accordance with 
section 172(b)(2) and the regulations thereunder, as follows:

Gross income................................................    $220,000
Deductions:
  Capital gains deduction...................................  Disallowed
  Business deductions.......................................     120,000
                                                 -------------
    Taxable income per section 172(b)(2)....................     100,000


In this case, the $60,000 increase in the 1972 taxable income as 
redetermined and the $30,000 decrease in the amount of the 1973 net 
operating loss remaining as a carryover to 1974 (i.e., the remaining 
1972 net operating loss after an initial decrease of $40,000 resulting 
from the 1973 taxable income before redetermination) is entirely 
attributable to the disallowance of the capital gains deduction. The 
limitation on the amount treated as items of tax preference is computed 
as follows:

Items of tax preference computed without regard to this
 section:
  Capital gains.............................................     $60,000
  Excess amortization of certified pollution control              45,000
   facilities...............................................
                                                 -------------
                                                                 105,000
Less: Lesser of capital gains deduction (60,000) or amount      (30,000)
 of reduction in carryover due to its disallowance ($30,000)
                                                 -------------
                                                                  75,000
Plus: Amount of reduction of carryover (due to disallowance       20,000
 of capital gains deduction) attributable to excess tax
 preferences................................................
                                                 -------------
    Limitation..............................................      95,000
