If an individual is a dependent of a taxpayer for any taxable year of such taxpayer beginning in a calendar year, such individual shall be treated as having no dependents for any taxable year of such individual beginning in such calendar year.
An individual shall not be treated as a dependent of a taxpayer under subsection (a) if such individual has made a joint return with the individual’s spouse under section 6013 for the taxable year beginning in the calendar year in which the taxable year of the taxpayer begins.
The term “dependent” does not include an individual who is not a citizen or national of the United States unless such individual is a resident of the United States or a country contiguous to the United States.
In the case of an individual who is permanently and totally disabled (as defined in section 22(e)(3)) at any time during such calendar year, the requirements of subparagraph (A) shall be treated as met with respect to such individual.
If the parents of an individual may claim such individual as a qualifying child but no parent so claims the individual, such individual may be claimed as the qualifying child of another taxpayer but only if the adjusted gross income of such taxpayer is higher than the highest adjusted gross income of any parent of the individual.
The term “custodial parent” means the parent having custody for the greater portion of the calendar year.
The term “noncustodial parent” means the parent who is not the custodial parent.

An individual shall not be treated as a member of the taxpayer’s household if at any time during the taxable year of the taxpayer the relationship between such individual and the taxpayer is in violation of local law.
The terms “brother” and “sister” include a brother or sister by the half blood.
Subparagraphs (A) and (C) shall cease to apply as of the first taxable year of the taxpayer beginning after the calendar year in which there is a determination that the child is dead (or, if earlier, in which the child would have attained age 18).
