Title 26 › Subtitle Subtitle F— - Procedure and Administration › Chapter CHAPTER 79— - DEFINITIONS › § 7703
Decides whether someone counts as married for certain tax rules. Marriage is checked at the end of the tax year. If a spouse dies during the year, use the time of death instead. If a person is legally separated by a court order (divorce or separate maintenance), they are not treated as married. For some parts of the tax code, a married person who files a separate return is looked at under three facts: they keep a home that is the main home of a qualifying child for more than half the year and can claim that child; they pay more than half the cost of running that home; and their spouse did not live in that home during the last 6 months of the year.
