                               (CONTINUED)
 
Procedure and Administration--Table of Contents
 
Sec.  1.6013-4  Applicable rules.

    (a) Status as husband and wife. For the purpose of filing a joint 
return under section 6013, the status as husband and wife of two 
individuals having taxable years beginning on the same day shall be 
determined:
    (1) If the taxable year of each individual is the same, as of the 
close of such year; and
    (2) If the close of the taxable year is different by reason of the 
death of one spouse, as of the time of such death.

An individual legally separated from his spouse under a decree of 
divorce or of separate maintenance shall not be considered as married. 
However, the mere fact that spouses have not lived together during the 
course of the taxable year shall not prohibit them from making a joint 
return. A husband and wife who are separated under an interlocutory 
decree of divorce retain the relationship of husband and wife until the 
decree becomes final. The fact that the taxpayer and his spouse are 
divorced or legally separated at any time after the close of the taxable 
year shall not deprive them of their right to file a joint return for 
such taxable year under section 6013.
    (b) Computation of income, deductions, and tax. If a joint return is 
made, the gross income and adjusted gross income of husband and wife on 
the joint return are computed in an aggregate amount and the deductions 
allowed and the taxable income are likewise computed on an aggregate 
basis. Deductions limited to a percentage of the adjusted gross income, 
such as the deduction for charitable, etc., contributions and gifts, 
under section 170, will be allowed with reference to such aggregate 
adjusted gross income. A similar rule is applied in the case of the 
limitation of section 1211(b) on the allowance of losses resulting from 
the sale or exchange of capital assets (see Sec.  1.1211-1). Although 
there are two taxpayers on a joint return, there is only one taxable 
income. The tax on the joint return shall be computed on the aggregate 
income and the liability with respect to the tax shall be joint and 
several. For computation of tax in the case of a joint return, see Sec.  
1.2-1. For tax in the case of a joint return of husband and wife 
electing to pay the optional tax under section 3, see Sec.  1.3-1. For 
the election not to show on a joint return the amount of tax due in 
connection therewith, see paragraph (c) of Sec.  1.6014-1 and paragraph 
(d) of Sec.  1.6014-2. For separate computations of the self-employment 
tax of each spouse on a joint return, see paragraph (b) of Sec.  1.6017-
1.
    (c) Definition of executor or administrator. For purposes of section 
6013 the term ``executor or administrator'' means the person who is 
actually appointed to such office and not a person who is merely in 
charge of the property of the decedent.
    (d) Return signed under duress. If an individual asserts and 
establishes that he or she signed a return under duress, the return is 
not a joint return. The individual who signed such return under duress 
is not jointly and severally liable for the tax shown on the return or 
any deficiency in tax with respect to the return. The return is adjusted 
to reflect only the tax liability of the individual who voluntarily 
signed the return, and the liability is determined at the applicable 
rates in section 1(d) for married individuals filing separate returns. 
Section 6212 applies to the assessment of any deficiency in tax on such 
return.
