Sec. 1.1348-2  Computation of the fifty-percent maximum tax on earned income.

    (a) Computation of tax for taxable years beginning after 1971. If, 
for a taxable year beginning after December 31, 1971, an individual has 
earned taxable income (as defined in paragraph (d) of this section) 
which exceeds the applicable amount in column (1) of table A, the tax 
imposed by section 1 for such year shall be the sum of:
    (1) The applicable amount in column (2) of table A.
    (2) 50 percent of the amount by which earned taxable income exceeds 
the applicable amount in column (1) of table A, and
    (3) The amount by which the tax imposed by chapter 1 on the entire 
taxable income exceeds a tax so computed on earned taxable income, such 
computations to be made without regard to section 1348 or 1301.

a taxable year beginning after December 31, 1970, and before January 1, 
1972, an individual has earned taxable income (as defined in paragraph 
(d) of this section) which exceeds the applicable amount in column (1) 
of table B, the tax imposed by section 1 for such year shall be the sum 
of:
    (1) The applicable amount in column (2) of table B,
    (2) 60 percent of the amount by which earned taxable income exceeds 
the applicable amount in column (1) of table B, and
    (3) The amount by which the tax imposed by chapter 1 on the entire 
taxable income exceeds a tax so computed on earned taxable income, such 
computations to be made without regard to section 1348 or 1301.

------------------------------------------------------------------------

    (c) Short taxable periods. If a taxpayer is required under section 
443(a)(1) to make a return for a period of less than 12 months, the tax 
under section 1348 and this section shall be determined by placing his 
taxable income, earned net income, adjusted gross income, and items of 
tax preference on an annual basis in accordance with section 443 and the 
regulations thereunder. If a taxable year referred to in paragraph 
(d)(3)(i)(a) of this section is a period of less than 12 months for 
which a return is required under section 443(a)(1), the average 
described in such paragraph shall also be determined by placing the 
items of tax preference for such period on an annual basis in accordance 
with section 443 and the regulations thereunder. If a return for a 
period of less than 12 months is required under section 443(a)(3) for 
any taxable year referred to in paragraph (d)(3)(i)(a) of this section, 
section 1348 and this section shall not apply unless such period is 
reopened by the taxpayer as provided by section 6851(b).
    (d) Earned taxable income--(1) In general. For purposes of section 
1348 and this section, the term earned taxable income means the excess 
of (i) the portion of taxable income which, under subparagraph (2) of 
this paragraph, is attributable to earned net income over (ii) the tax 
preference offset (as defined in subparagraph (3) of this paragraph). 
For purposes of computing the alternative tax under section 1201, earned 
taxable income shall not exceed the excess of taxable income over 50 
percent of the net capital gain (net section 1201 gain for taxable years 
beginning before January 1, 1977).
    (2) Taxable income attributable to earned net income. The portion of 
taxable income which is attributable to

[[Page 671]]

earned net income shall be determined by multiplying taxable income by a 
fraction (not exceeding one), the numerator of which is earned net 
income, and the denominator of which is adjusted gross income. For 
purposes of this subparagraph the term earned net income means the 
excess of the total of earned income (as defined in Sec. 1.1343-(a)) 
over the total of any deductions which are required to be taken into 
account under section 62 in determining adjusted gross income and are 
properly allocable to or chargeable against earned income. Deductions 
are properly allocable to or chargeable against earned income if, and to 
the extent that, they are allowable in respect of expenses paid or 
incurred in connection with the production of earned income and have not 
been taken into account in determining the net profits of a trade or 
business in which both personal services and capital are material income 
producing factors (as defined in Sec. 1.1348-3(a)(3)). Except as 
otherwise provided, deductions properly allocable to or chargeable 
against earned income include:
    (i) Deductions attributable to a trade or business from which earned 
income is derived, except that if less than all the gross income from a 
trade or business constitutes earned income, only a ratable portion of 
the deductions attributable to such trade or business is allowable in 
respect of expenses paid or incurred in connection with the production 
of earned income,
    (ii) Deductions consisting of expenses paid or incurred in 
connection with the performance of services as an employee,
    (iii) The deductions described in section 62(7) and allowable by 
sections 404 and 405(c),
    (iv) The deduction allowable by section 217,
    (v) The deduction allowable by section 1379(b)(3), and
    (vi) A net operating loss deduction to the extent that the net 
operating losses carried to the taxable year are properly allocable to 
or chargeable against earned income.

A net operating loss carried to the taxable year is properly allocable 
to or chargeable against earned income in such year to the extent of the 
excess (if any) of the deductions for the loss year which are properly 
allocable to or chargeable against earned income and which are allowable 
under section 172(d) in determining a net operating loss, over the 
earned income for the loss year. If the excess described in the 
preceding sentence is less than the entire net operating loss, such 
excess and the balance of such loss shall be deemed to reduce taxable 
income ratably for any taxable year to which such loss may be carried. 
See examples (3) and (4) in subparagraph (4) of this paragraph.
    (3) Tax preference offset. (i) For purposes of subparagraph (1) of 
this paragraph, the tax preference offset is the amount by which the 
greater of:
    (A) The average of the taxpayer's items of tax preference for the 
taxable year and the four preceding taxable years, or
    (B) The taxpayer's items of tax preference for the taxable year,

exceeds $30,000.
    (ii) The items of tax preference to be taken into account under 
subdivision (i) of this subparagraph for any taxable year shall be those 
items of tax preference referred to in section 57(a) and the regulations 
thereunder for the taxable year, but excluding any amount not taken into 
account in computing the tax under section 56(a) and the regulations 
thereunder for such taxable year. The items of tax preference to be 
taken into account by an individual for any taxable year in which such 
individual is or was a nonresident alien shall not include items of tax 
preference which are not effectively connected with the conduct of a 
trade or business within the United States.
    (iii) Taxable years ending before January 1, 1970 shall not be 
included in computing the average described in subdivision (i)(A) of 
this subparagraph. Thus, for example, the tax preference offset for a 
taxable year ending on December 31, 1973, is the amount by which the 
average of the taxpayer's items of tax preference for 1970, 1971, 1972, 
and 1973, or the taxpayer's items of tax

[[Page 672]]

preference for 1973, whichever is greater, exceeds $30,000. Taxable 
years during which the taxpayer was not in existence shall not be 
included in computing the average described in subdivision (i)(A) of 
this subparagraph. A fractional part of a year which is treated as a 
taxable year under sections 441(b) and 7701(a)(23) shall be treated as a 
taxable year for purposes of this section for special rules if a taxable 
year referred to in subdivision (i)(A) of this subparagraph is a period 
of less than 12 months for which a return is required under section 
443(a)(1).
    (iv) If for the current taxable year the taxpayer and his spouse (or 
the estate of such spouse) file a joint return together, the items of 
tax preference for a preceding taxable year taken into account under 
subdivision (i)(A) of this subparagraph shall be the sum of the items of 
tax preference of the taxpayer and his spouse for such preceding year 
even though a joint return was not, or could not have been, filed by the 
taxpayer and such spouse for such preceding taxable year. If for the 
current taxable year the taxpayer (A) is no longer married to a spouse 
to whom he was married for a preceding taxable year taken into account 
under subdivision (i)(A) of this subparagraph and files a return as a 
single person, head of household, or surviving spouse for such current 
taxable year, or (B) is married to a spouse other than the spouse to 
whom he was married for a preceding taxable year taken into account 
under subdivision (i)(A) of this subparagraph, his items of tax 
preference shall be computed as if he were not married during such 
preceding taxable year.
    (v) The sum of the items of tax preference of an estate or trust 
shall, for purposes of this paragraph, be apportioned between the estate 
or trust and the beneficiary in the manner and to the extent provided by 
section 58(c)(1) and the regulations thereunder.
    (vi) If an item of gross income in respect of a decedent is 
includible in the gross income of a taxpayer and is treated as earned 
income in the hands of the taxpayer by reason of Sec. 1.1348-3(a)(4), 
the items of tax preference for a taxable year taken into account under 
subdivision (i) of this subparagraph shall be the sum of the taxpayer's 
items of tax preference for such taxable year and the decedent's items 
of tax preference for any taxable year of the decedent (including a 
short taxable year described in section 441(b)(3)) which ends with or 
within such taxable year of the taxpayer. For purposes of this 
subdivision, if a taxpayer (such as the estate of the decedent or a 
testamentary trust created by the decedent) has not been in existence 
for the number of preceding taxable years specified in subdivision 
(i)(A) or (iii) of this subparagraph, the items of tax preference for 
preceding taxable years taken into account shall be the taxpayer's items 
of tax preference for each of its preceding taxable years plus the 
decedent's items of tax preference for that number of the most recent 
taxable years of the decedent ending prior to the taxpayer's earliest 
taxable year which, when added to the taxpayer's preceding taxable 
years, equals such number of preceding taxable years specified in 
subdivision (i)(A), or (iii). The increase, if any, in the taxpayer's 
tax preference offset computed under this subdivision shall not exceed 
the amount by which the taxpayer's taxable income attributable to earned 
net income, computed as provided in Sec. 1.1348-2(d)(2) and including 
the item of gross income in respect of a decedent, exceeds the 
taxpayer's taxable income attributable to earned net income computed 
without regard to such item of gross income.
    (4) Illustrations. The provisions of this section may be illustrated 
by the following examples:

    Example 1. (i) H and W, married calendar-year taxpayers filing a 
joint return, have the following items of income, deductions, and tax 
preference for 1976:

(a) Salary........................................   $155,000
(b) Dividends and interest........................     60,000
                                                   -----------
    Total.........................................    215,000
(c) Deductible travel expenses of employee              5,000
 allocable to earned income.......................
                                                   -----------
(d) Adjusted gross income....................................   $210,000
(e) Exemptions and itemized deductions.......................     38,000
                                                   ------------
(f) Taxable income...........................................    172,000


    In addition, the taxpayers have tax preference items for 1976 of 
$80,000 attributable to the exercise of a qualified stock option and 
total tax preference items of $300,000 for the years 1972 through 1975. 
Since the items

[[Page 673]]

of tax preference for 1976 exceed the average of the items of tax 
preference for the years 1972 through 1976, the tax preference offset 
for 1976 is $50,000 ($80,000-$30,000).
    (ii) H and W have earned taxable income of $72,857 determined in the 
following manner:

(a) Earned income............................................   $155,000
(b) Earned net income ($155,000-$5,000)......................    150,000
(c) Taxable income...........................................    172,000
(d) Adjusted gross income....................................    210,000
(e) Taxable income attributable to earned net
 income:
  $172,000(c) x ($150,000(b) / $210,000(d)........   $122,857
(f) Tax preference offset.........................     50,000
                                                   -----------

 2(a).........................................................
(b) 50 pct of amount by which $72,857 (earned taxable income)     10,429
 exceeds $52,000 (applicable amount from col. (1) of table A,
 Sec.  1.1348-2(a))..........................................
(c) Tax computed under section 1 on $172,000           $91,740
 (taxable income)...................................

(e) Item (c) minus item (d)...................................   962,449
(f) Tax (total of items (a), (b), and (e))....................    90,938


    Example 2. (i) H and W, married calendar-year taxpayers filing a 
joint return, have the following items of income, deductions, and tax 
preference for 1976:

(a) Salary........................................   $210,000
(b) Dividends and interest........................     20,000
(c) Net long-term capital gains...................    100,000
                                                   -----------
    Total.........................................    330,000
(d) Sec. 1202 deduction (\1/2\ of net long-term        50,000
 capital gains)...................................
                                                   -----------
(e) Adjusted gross income....................................   $280,000
(f) Exemptions and itemized deductions.......................     40,000
                                                   ------------
(g) Taxable income...........................................    240,000


    The taxpayers' tax preference item for 1976 is one-half of the net 
long-term capital gains of $100,000, or $50,000. The taxpayers have no 
items of tax preference for the years 1972 through 1975. Accordingly, 
their tax preference offset for 1976 is $20,000 ($50,000-$30,000).
    (ii) H and W have earned taxable income of $160,000, determined in 
the following manner:

(a) Earned net income........................................   $210,000
(b) Taxable income...........................................    240,000
(c) Adjusted gross income....................................    280,000
(d) Taxable income attributable to earned net income:
    $240,000(b) x ($210,000(a) / $280,000(c)).....    180,000
(e) Tax preference offset.........................    $20,000
                                                   -----------
(f) Earned taxable income....................................   $160,000


    (iii) The tax imposed by section 1 is $122,560, determined pursuant 
to section 1348 in the following manner:

(a) Applicable amount from col. (2) of table A, Sec.  1.1348-   $18,060
 2(a)........................................................
(b) 50 pct of amount by which $160,000 (earned taxable            54,000
 income) exceeds $52,000 (applicable amount from col. (1) of
 table A, Sec.  1.1348-2(a))................................
(c) Tax computed under section 1201(b) on $240,000
 (taxable income):
  (1) Tax under section 1201(b)(1) (tax under        $104,080
   section 1 on $190,000 (taxable income excluding
   capital gains))................................
  (2) Tax under section 1201(b)(2) (25 pct of          12,500
   subsection (d) gain of $50,000)................
  (3) Tax under section 1201(b)(3) (tax under          17,500
   section 1 on $240,000 (taxable income) less tax
   under section 1 on $215,000 (amount subject to
   tax under section 1201(b)(1) plus 50 pct of
   subsection (d) gain)) ($138,980-$121,480)......
                                                   -----------
    Total.........................................    134,080
(d) Tax computed under section 1 on $160,000           83,580
 (earned taxable income)..........................
                                                   -----------
(e) Item (c) through item (d)................................     50,500
                                                   ------------
(f) Tax (total of items (a), (b), and (e))...................   $122,560


    Example 3. (i) A, an unmarried calendar year taxpayer engaged in the 
practice of law, has the following items of income and deductions for 
1973 and 1976:

------------------------------------------------------------------------
                                                       1973       1976
------------------------------------------------------------------------
Gross income from law practice....................   $240,000   $100,000
Dividends.........................................     60,000     20,000
Expense paid in law practice......................     50,000    160,000
Investment interest...............................     30,000     10,000
Casualty loss on personal residence (amount in excess of          50,000
 $100).......................................................
------------------------------------------------------------------------

    (ii) For 1976, A's deductions exceed his gross income, and his 
taxable income is therefore zero. In addition, A has a net operating 
loss of $100,000 (i.e., the excess of his deductions of $220,000 over 
his gross income of $120,000), which may be carried back to 1973. In 
computing his taxable income and earned taxable income for 1973, $60,000 
(i.e., the excess of the expenses paid in A's law practice of $160,000, 
over his gross income from his law practice of $100,000) of the net 
operating loss deduction is properly allocable to or chargeable against 
earned income.
    (iii) A's recomputed taxable income and earned taxable income for 
1973 are $119,250 and $103,350 respectively, determined in the following 
manner:

Gross income ($240,000 + $60,000)............................   $300,000
Adjusted gross income ($300,000 - $50,000 - $100,000)........    150,000
Taxable income ($150,000 - $30,000 - $750)...................    119,250
Earned net income ($240,000 - $50,000 - $60,000).............    130,000
Earned taxable income ($130,000 / $150,000 x $119,250).......   $103,350



[[Page 674]]

    Example 4. The facts are the same as in example (3) except that A's 
gross income from his law practice for 1973 is $40,000. Thus, for 1973, 
A's deductions (including the net operating loss deduction) exceed his 
gross income, and his recomputed taxable income is therefore zero. The 
taxable income subtracted from the net operating loss to determine the 
carryback to 1974 is $20,000 (i.e., $40,000 + $60,000 - $50,000 - 
$30,000), and thus the net operating loss carryback to 1974 is $20,000 
(i.e., $40,000 + $60,000 - $50,000 - $30,000), and thus the net 
operating loss carryback from 1976 to 1974 is $80,000 (i.e., $100,000 - 
$20,000). Of this amount, $48,000 ($80,000 x [$60,000 (the excess of the 
expenses paid in 1976 in A's law practice over his gross income from his 
law practice) / $100,000 (A's net operating loss for 1976)]) is properly 
allocable to or chargeable against earned income, and must be taken into 
account in recomputing A's taxable income and earned taxable income for 
1974.
    Example 5. A, an unmarried calendar year taxpayer, receives a salary 
of $80,000 from Corporation X in 1975 and also owns and operates a 
laundry in which both his capital and services are material income 
producing factors. A incurs no section 62 expenses with respect to the 
salary income. In 1975 the laundry, a sole proprietorship, has gross 
income of $100,000 and business expenses deductible under section 62 of 
$80,000. A reasonable allowance as compensation for A's personal 
services rendered by him in his laundry business would be $12,000. The 
net profits of the laundry business were $20,000.
    A's earned income from the laundry business is limited to $6,000 (30 
percent of $20,000). A's total earned income is $36,000 
($80,000+$60,000). Since the section 62 deductions of the laundry 
business have already been taken into account in computing net profits, 
they are not again taken into account in computing earned net income. 
Accordingly, A's earned net income for 1975 is $86,000.
    Example 6. The facts are the same as example (5) except that the 
gross income of the laundry is $130,000 and the net profits from the 
laundry are $50,000. A's earned income from the laundry is $12,000. Even 
though the 30-percent-of-net profits limitation has not resulted in a 
reduction of A's earned income from the laundry, the expenses deducted 
in computing net profits do not reduce earned income. Accordingly, both 
the earned income and the earned net income of A for 1975 are $92,000.
    Example 7. The facts are the same as example (5) except that the 
gross income of the laundry is $60,000 and the laundry has a net loss of 
$20,000. A's earned income from the laundry is $12,000. Since the 
laundry does not have net profits, the expenses of the laundry have not 
been taken into account in computing the net profits limitation. 
Accordingly, a ratable portion of deductible expenses of the laundry 
must be allocated to the earned income from the laundry in accordance 
with Sec. 1.1348-2(d)(2); $16,000 of the expenses are allocated to the 
earned income ($12,000/$60,000x$80,000). A's total earned income for 
1975 is $92,000, and his earned net income is $76,000 ($92,000 minus 
$16,000).
