     CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY
 
PART 1--INCOME TAXES--Table of Contents
 
Sec. 1.4-3  Husband and wife filing separate returns.

    (a) In general. If the separate adjusted gross income of a husband 
is less than $5,000 and the separate adjusted gross income of his wife 
is less than $5,000, and if each is required to file a return, the 
husband and the wife must each elect to pay the optional tax imposed 
under section 3 or neither may so elect. If the separate adjusted gross 
income of each spouse is $5,000 or more, then

[[Page 26]]

neither spouse can elect to pay the optional tax imposed under section 
3. If the adjusted gross income of one spouse is $5,000 or more and that 
of the other spouse is less than $5,000, the election to pay the 
optional tax imposed under section 3 may be exercised by the spouse 
having adjusted gross income of less than $5,000 only if the spouse 
having adjusted gross income of $5,000 or more, in computing taxable 
income, uses the standard deduction provided by section 141. If the 
spouse having adjusted gross income of $5,000 or more does not use the 
standard deduction, then the spouse having adjusted gross income of less 
than $5,000 may not elect to pay the optional tax and must compute 
taxable income without regard to the standard deduction. Accordingly, if 
the spouse having adjusted gross income of $5,000 or more itemizes the 
deductions allowed by sections 161 and 211 in computing taxable income, 
the spouse having adjusted gross income of less than $5,000 must also 
compute taxable income by itemizing the deductions allowed by sections 
161 and 211, and must pay the tax imposed by section 1. For rules 
relative to the election to take the standard deduction by husband and 
wife, see part IV (section 141 and following), subchapter B, chapter 1 
of the Code, and the regulations thereunder.
    (b) Taxable years beginning after December 31, 1963, and before 
January 1, 1970. (1) In the case of a husband and wife filing a separate 
return for a taxable year beginning after December 31, 1963, and before 
January 1, 1970, the optional tax imposed by section 3 shall be--
    (i) For taxable years beginning in 1964, the lesser of the tax shown 
in Table IV (relating to the 10-percent standard deduction for married 
persons filing separate returns) or Table V (relating to the minimum 
standard deduction for married persons filing separate returns) of 
section 3(a), and
    (ii) For a taxable year beginning after December 31, 1964, and 
before January 1, 1970, the lesser of the tax shown in Table IV 
(relating to the 10-percent standard deduction for married persons 
filing separate returns) or Table V (relating to minimum standard 
deduction for married persons filing separate returns) of section 3(b).
    (2) If the tax of one spouse is determined with regard to the 10-
percent standard deduction provided for in Table IV of section 3(a) or 
3(b) or if such spouse in computing taxable income uses the 10-percent 
standard deduction provided for in section 141(b), then the minimum 
standard deduction provided for in Table V of section 3(a) or 3(b) shall 
not apply in the case of the other spouse, if such spouse elects to pay 
the optional tax imposed under section (3). Thus, if a husband and wife 
compute their tax with reference to the standard deduction, one cannot 
elect to use the 10-percent standard deduction and the other elect to 
use the minimum standard deduction. However, an individual described in 
section 141(d)(2) may elect pursuant to such section and the regulations 
thereunder to pay the tax shown in Table V of section 3(a) or 3(b) in 
lieu of the tax shown in Table IV of section 3(a) or 3(b). See section 
141(d) and the regulations thereunder for rules relating to the standard 
deduction in the case of married individuals filing separate returns.
    (c) Taxable years beginning after December 31, 1969. (1) In the case 
of a husband and wife filing a separate return for a taxable year 
beginning after December 31, 1969, the optional tax imposed by section 3 
shall be the lesser of the tax shown in--
    (i) The table prescribed under section 3 applicable to such taxable 
year in the case of married persons filing separate returns which 
applies the percentage standard deduction, or
    (ii) The table prescribed under section 3 applicable to such taxable 
year in the case of married persons filing separate returns which 
applies the low income allowance.
    (2) If the tax of one spouse is determined by the table described in 
subparagraph (1)(i) of this paragraph or if such spouse in computing 
taxable income uses the percentage standard deduction provided for in 
section 141(b), then the table described in subparagraph (1)(ii) of this 
paragraph shall not apply in the case of the other spouse, if such other 
spouse elects to pay the optional tax imposed under section 3. Thus, if 
a husband and wife compute

[[Page 27]]

the tax with reference to the standard deduction, one cannot elect to 
use the percentage standard deduction and the other elect to use the low 
income allowance. A married individual described in section 141(d)(2) 
may elect pursuant to such section and the regulations thereunder to pay 
the tax shown in the table described by subparagraph (1)(ii) of this 
paragraph in lieu of the tax shown in the table described by 
subparagraph (1)(i) of this paragraph. See section 141(d) and the 
regulations thereunder for rules relating to the standard deduction in 
the case of married individuals filing separate returns.
    (d) Determination of marital status. For the purpose of applying the 
restrictions upon the right of a married person to elect to pay the tax 
under section 3, (1) the determination of marital status is made as of 
the close of the taxpayer's taxable year or, if his spouse died during 
such year, as of the date of death; (2) a person legally separated from 
his spouse under a decree of divorce or separate maintenance on the last 
day of his taxable year (or the date of death of his spouse, whichever 
is applicable) is not considered as married; and (3) with respect to 
taxable years beginning after December 31, 1969, a person, although 
considered as married within the meaning of section 143(a), is 
considered as not married if he lives apart from his spouse and 
satisfies the requirements set forth in section 143(b). See section 143 
and the regulations thereunder.
