In the case of an individual to whom this subsection applies in a taxable year for purposes of so much of this title (other than this section and section 7654) as relates to the taxes imposed by this chapter, the Virgin Islands shall be treated as including the United States. who is a bona fide resident of the Virgin Islands during the entire taxable year, who, on his return of income tax to the Virgin Islands, reports income from all sources and identifies the source of each item shown on such return, and who fully pays his tax liability referred to in section 934(a) to the Virgin Islands with respect to such income, In the case of a joint return, this section shall be applied on the basis of the residence of the spouse who has the greater adjusted gross income (determined without regard to community property laws) for the taxable year.
