(1)#
Except as provided in subds. 2. and 3. and par. (e), a husband and a wife may file a joint return for income tax purposes even though one of the spouses has no gross income or no deductions.
(2)#
No joint return may be filed if either the husband or wife at any time during the taxable year is a nonresident alien, unless an election is in effect for the taxable year under section 6013 (g) or (h) of the internal revenue code.
(3)#
No joint return may be filed if the husband and wife have different taxable years, except that if their taxable years begin on the same day and end on different days because of the death of either or both the joint return may be filed with respect to the taxable year of each unless the surviving spouse remarries before the close of his or her taxable year or unless the taxable year of either spouse is a fractional part of a year under section 443 (a) (1) of the internal revenue code.
