        the same ratio to such credit as such excess bears to $10,000.

        multiple of $10 shall be rounded to the next lowest $10.

                security taxes.--The term `social security taxes' shall

section shall not apply to insurance which constitutes medical care 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.

Summary: 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.
