        subsection and subsection (d)) be allowed under subsection (a) 
        shall be reduced (but not below zero) by an amount which bears 
        the same ratio to such credit as such excess bears to $10,000. 
        Any reduction under the preceding sentence which is not a 
        multiple of $10 shall be rounded to the next lowest $10.
            ``(3) Applicable dollar amount.--The term `applicable 
        dollar amount' means--
                    ``(A) in the case of a taxpayer filing a joint 
                return, $50,000,

                        amounts received by the taxpayer during the 
                        calendar year in which the taxable year begins,

                        during the calendar year in which the taxable 
                        year begins.
                    ``(B) Coordination with special refund of social 
                security taxes.--The term `social security taxes' shall 
                not include any taxes to the extent the taxpayer is 
                entitled to a special refund of such taxes under 
                section 6413(c).
                    ``(C) Special rule.--Any amounts paid pursuant to

                agreements entered into by American employers with 
                respect to foreign affiliates) which are equivalent to 
                the taxes referred to in subparagraph (A)(i) shall be 
                treated as taxes referred to in such subparagraph.
    ``(e) Coordination With Other Provisions.--
            ``(1) Deduction for medical expenses.--The amount taken 
        into account in computing the credit under subsection (a) shall 
        not be taken into account in computing the amount allowable to 
        the taxpayer as a deduction under section 213(a).
            ``(2) Self-employed individuals allowed either deduction or 
        credit for health insurance.--No credit shall be allowed under 
        this section to a taxpayer for a taxable year if any amount is 
        allowed as a deduction to such taxpayer for such year under 
        section 162(l).
    ``(f) Expenses Must Be Substantiated.--A payment for insurance to 
which subsection (a) applies may be taken into account under this 
section only if the taxpayer substantiates such payment in such form as 
the Secretary may prescribe.
    ``(g) Section Not To Apply to Long-Term Care Insurance.--This 
section shall not apply to insurance which constitutes medical care by 
reason of section 213(d)(1)(C).''
    (b) Clerical Amendment.--The table of sections for subpart C of 
part IV of subchapter A of chapter 1 of such Code is amended by 
striking the last item and inserting the following new items:

                              ``Sec. 35. Health insurance costs.
                              ``Sec. 36. Overpayments of tax.''
    (c) Effective Date.--The amendments made by this section shall 
apply to taxable years beginning after the date of the enactment of 
this Act.
Limits the full credit to individuals whose adjusted gross income is under $30,000 ($50,000 if filing a joint return). Disallows any credit to a married individual filing a separate return, but treats married individuals living apart and filing separate returns as not married (thus qualifying them for the credit). Prescribes a formula for phase-out of the credit for taxpayers with an adjusted gross income exceeding $30,000 ($50,000 for a joint return) by less than $10,000.
Allows self-employed individuals to elect such credit or the deduction for medical expenses, but not both.
States that such credit does not apply to long- term health care insurance.
