``SEC. 121. EXCLUSION OF GAIN FROM SALE OF PRINCIPAL RESIDENCE.

    ``(a) General Rule.--Gross income does not include gain from the

or more.
    ``(b) Special Rules.--
            ``(1) Property held jointly by husband and wife.--For

                    ``(A) property is held by a husband and wife as 
                joint tenants, tenants by the entirety, or community 
                property,
                    ``(B) such husband and wife make a joint return 
                under section 6013 for the taxable year of the sale or 
                exchange, and
                    ``(C) one spouse satisfies the holding and use 
                requirements of subsection (a) with respect to such 
                property,
        then both husband and wife shall be treated as satisfying the 
        holding and use requirements of subsection (a) with respect to 
        such property.
            ``(2) Property of deceased spouse.--For purposes of this 
        section, in the case of an unmarried individual whose spouse is 
        deceased on the date of the sale or exchange of property, if 
        the deceased spouse (during the 5-year period ending on the 
        date of the sale or exchange) satisfied the holding and use 
        requirements of subsection (a) with respect to such property, 
        then such individual shall be treated as satisfying the holding 
        and use requirements of subsection (a) with respect to such 
        property.
            ``(3) Tenant-stockholder in cooperative housing 
        corporation.--For purposes of this section, if the taxpayer 
        holds stock as a tenant-stockholder (as defined in section 216) 
        in a cooperative housing corporation (as defined in such 
        section), then--
                    ``(A) the holding requirements of subsection (a) 
                shall be applied to the holding of such stock, and
                    ``(B) the use requirements of subsection (a) shall 
                be applied to the house or apartment which the taxpayer 
                was entitled to occupy as such stockholder.
            ``(4) Involuntary conversions.--For purposes of this 
        section, the destruction, theft, seizure, requisition, or 
        condemnation of property shall be treated as the sale of such 
        property.
            ``(5) Property used in part as principal residence.--In the 
        case of property only a portion of which, during the 5-year 
        period ending on the date of the sale or exchange, has been 
        owned and used by the taxpayer as his principal residence for 
        periods aggregating 3 years or more, this section shall apply 
        with respect to so much of the gain from the sale or exchange 
        of such property as is determined, under regulations prescribed 
        by the Secretary, to be attributable to the portion of the 
        property so owned and used by the taxpayer.
            ``(6) Determination of marital status.--In the case of any 
        sale or exchange, for purposes of this section--
                    ``(A) the determination of whether an individual is 
                married shall be made as of the date of the sale or 
                exchange; and
                    ``(B) an individual legally separated from his 
                spouse under a decree of divorce or of separate 
                maintenance shall not be considered as married.
            ``(7) Application of section 1033.--In applying section 
        1033 (relating to involuntary conversions), the amount realized 
        from the sale or exchange of property shall be treated as being 
        the amount determined without regard to this section, reduced 
        by the amount of gain not included in gross income pursuant to 
        an election under this section.
            ``(8) Property acquired after involuntary conversion.--If 
        the basis of the property sold or exchanged is determined (in 
        whole or in part) under subsection (b) of section 1033 
        (relating to basis of property acquired through involuntary 
        conversion), then the holding and use by the taxpayer of the 
        converted property shall be treated as holding and use by the 
        taxpayer of the property sold or exchanged.
            ``(9) Determination of use during periods of out-of-
        residence care.--In the case of a taxpayer who--
                    ``(A) becomes physically or mentally incapable of 
                self-care, and
                    ``(B) owns property and uses such property as the 
                taxpayer's principal residence during the 5-year period 
                described in subsection (a) for periods aggregating at 
                least 1 year,
        then the taxpayer shall be treated as using such property as 
        the taxpayer's principal residence during any time during such 
        5-year period in which the taxpayer owns the property and 
        resides in any facility (including a nursing home) licensed by 
a State or political subdivision to care for an individual in the 
taxpayer's condition.
    ``(c) Election to Have Section Not Apply.--If the taxpayer so 
elects with respect to any sale or exchange, this section shall not 
apply to such sale or exchange.''
