                               (CONTINUED)
 
Procedure and Administration--Table of Contents
 
Sec.  1.7703-1  Determination of marital status.

    (a) General rule. The determination of whether an individual is 
married shall be made as of the close of his taxable year unless his 
spouse dies during his taxable year, in which case such determination 
shall be made as of the time of such death; and, except as provided in 
paragraph (b) of this section, an individual shall be considered as 
married even though living apart from his spouse unless legally 
separated under a decree of divorce or separate maintenance. The 
provisions of this paragraph may be illustrated by the following 
examples:

    Example (1). Taxpayer A and his wife B both make their returns on a 
calendar year basis. In July 1954, they enter into a separation 
agreement and thereafter live apart, but no decree of divorce or 
separate maintenance is issued until March 1955. If A itemizes and 
claims his actual deductions on his return for the calendar year 1954, B 
may not elect the standard deduction on her return since B is considered 
as married to A (although permanently separated by agreement) on the 
last day of 1954.
    Example (2). Taxpayer A makes his returns on the basis of a fiscal 
year ending June 30. His wife B makes her returns on the calendar year 
basis. A died in October 1954. In such case, since A and B were married 
as of the date of death, B may not elect the standard deduction for the 
calendar year 1954 if the income of A for the short taxable year ending 
with the date of his death is determined without regard to the standard 
deduction.

    (b) Certain married individuals living apart. (1) For purposes of 
Part IV of Subchapter B of Chapter 1 of the Code, an individual is not 
considered as married for taxable years beginning after December 31, 
1969, if (i) such individual is married (within the meaning of paragraph 
(a) of this section) but files a separate return; (ii) such individual 
maintains as his home a household which constitutes for more than one-
half of the taxable year the principal place of abode of a dependent (a) 
who (within the meaning of section 152 and the regulations thereunder) 
is a son, stepson, daughter, or stepdaughter of the individual, and (b) 
with respect to whom such individual is entitled to a deduction for the 
taxable year under section 151; (iii) such individual furnishes over 
half of the cost of maintaining such household during the taxable year; 
and (iv) during the entire taxable year such individual's spouse is not 
a member of such household.
    (2) For purposes of subparagraph (1)(ii)(a) of this paragraph, a 
legally adopted son or daughter of an individual, a child (described in 
paragraph (c)(2) of Sec.  1.152-2) who is a member of an individual's 
household if placed with such individual by an authorized placement 
agency (as defined in paragraph (c)(2) of Sec.  1.152-2) for legal 
adoption by such individual, or a foster child (described in paragraph 
(c)(4) of Sec.  1.152-2) of an individual if such child satisfies the 
requirements of section 152(a)(9) of the Code and paragraph (b) of Sec.  
1.152-1 with respect to such individual, shall be treated as a son or 
daughter of such individual by blood.
    (3) For purposes of subparagraph (1)(ii) of this paragraph, the 
household must actually constitute the home of the individual for his 
taxable year. However, a physical change in the location of such home 
will not prevent an individual from qualifying for the treatment 
provided in subparagraph (1) of this paragraph. It is not sufficient 
that the individual maintain the household without being its occupant.

The individual and the dependent described in subparagraph (1)(ii)(a) of 
this paragraph must occupy the household for more than one-half of the 
taxable year of the individual. However, the fact that such dependent is 
born or dies within the taxable year will not prevent an individual from 
qualifying for such treatment if the household constitutes the principal 
place of abode of such dependent for the remaining or preceding part of 
such taxable year. The individual and such dependent will be considered 
as occupying the household during temporary absences from the household 
due to special circumstances. A nonpermanent failure to occupy the 
common abode by reason of illness, education, business, vacation, 
military service, or a custody agreement under which a child or 
stepchild is absent for less than 6 months in the taxable year of the 
taxpayer, shall be considered a temporary absence due to special 
circumstances. Such absence will not prevent an individual from 
qualifying for the treatment provided in subparagraph (1) of this 
paragraph if (i) it is reasonable to assume that such individual or the 
dependent will return to the household and (ii) such individual 
continues to maintain such household or a substantially equivalent 
household in anticipation of such return.
    (4) An individual shall be considered as maintaining a household 
only if he pays more than one-half of the cost thereof for his taxable 
year. The cost of maintaining a household shall be the expenses incurred 
for the mutual benefit of the occupants thereof by reason of its 
operation as the principal place of abode of such occupants for such 
taxable year. The cost of maintaining a household shall not include 
expenses otherwise incurred. The expenses of maintaining a household 
include property taxes, mortgage interest, rent, utility charges, upkeep 
and repairs, property insurance, and food consumed on the premises. Such 
expenses do not include the cost of clothing, education, medical 
treatment, vacations, life insurance, and transportation. In addition, 
the cost of maintaining a household shall not include any amount which 
represents the value of services rendered in the household by the 
taxpayer or by a dependent described in subparagraph (1)(ii)(a) of this 
paragraph.
    (5) For purposes of subparagraph (1)(iv) of this paragraph, an 
individual's spouse is not a member of the household during a taxable 
year if such household does not constitute such spouse's place of abode 
at any time during such year. An individual's spouse will be considered 
to be a member of the household during temporary absences from the 
household due to special circumstances. A nonpermanent failure to occupy 
such household as his abode by reason of illness, education, business, 
vacation, or military service shall be considered a mere temporary 
absence due to special circumstances.
    (6) The provisions of this paragraph may be illustrated by the 
following example:

    Example. Taxpayer A, married to B at the close of the calendar year 
1971, his taxable year, is living apart from B, but A is not legally 
separated from B under a decree of divorce or separate maintenance. A 
maintains a household as his home which is for 7 months of 1971 the 
principal place of abode of C, his son, with respect to whom A is 
entitled to a deduction under section 151. A pays for more than one-half 
the cost of maintaining that household. At no time during 1971 was B a 
member of the household occupied by A and C. A files a separate return 
for 1971. Under these circumstances, A is considered as not married 
under section 143(b) for purposes of the standard deduction. Even though 
A is married and files a separate return A may claim for 1971 as his 
standard deduction the larger of the low income allowance up to a 
maximum of $1,050 consisting of both the basic allowance and additional 
allowance (rather than the basic allowance only subject to the $500 
limitation applicable to a separate return of a married individual) or 
the percentage standard deduction subject to the $1,500 limitation 
(rather than the $750 limitation applicable to a separate return of a 
married individual). See Sec.  1.141-1. For purposes of the provisions 
of part IV of subchapter B of chapter 1 of the Code and the regulations 
thereunder, A is treated as unmarried.
