        spouses in accordance with their respective ownership rights in 
        such property.

            ``(1) except as otherwise provided in this subsection, the

        section 62(a) (relating to contributions to medical savings 
        accounts) shall be allowed to the spouse with respect to whose 
        employment or self-employment such account relates,
            ``(5) the deductions allowable by section 151 (relating to

        spouse to claim 1 personal exemption and by allocating the 
        personal exemptions under section 151(c) (relating to 
        dependents) as provided in paragraph (7) or in such other 
        manner as the spouses agree,

        determined by multiplying the aggregate amount thereof by the 
        fraction--
                    ``(A) the numerator of which is such spouse's 
                adjusted gross income, and
                    ``(B) the denominator of which is the combined 
                adjusted gross incomes of the 2 spouses.
Any fraction determined under paragraph (7) shall be rounded to the 
nearest percentage point.

spouses had filed a joint return.

of this title (other than sections 1 and 63(c)) a combined return under
