# (a)

Every resident individual, as defined in section 12-701, subject to and required to pay the federal alternative minimum tax under Section 55 of the Internal Revenue Code shall pay, in addition to the tax imposed under section 12-700, the net Connecticut minimum tax. The tax shall be the difference computed by subtracting the tax imposed under subsection (a) of section 12-700 from the Connecticut minimum tax, as provided in subdivision (26) of subsection (a) of section 12-701. The provisions of this subsection shall apply to resident trusts and estates, as defined in said section 12-701, and, wherever reference is made in this section to resident individuals, such reference shall be construed to include resident trusts and estates, provided any reference to a resident individual's Connecticut adjusted gross income shall be construed, in the case of a resident trust or estate, to mean the resident trust or estate's Connecticut taxable income.

# (b)

Every nonresident individual, as defined in section 12-701, subject to and required to pay the federal alternative minimum tax under Section 55 of the Internal Revenue Code shall pay, in addition to the tax imposed under section 12-700, the net Connecticut minimum tax, as calculated herein. The tax shall be the difference computed by subtracting the tax imposed under subsection (b) of section 12-700 from the product of the nonresident individual's Connecticut minimum tax, as provided in subdivision (26) of subsection (a) of section 12-701, multiplied by a fraction, the numerator of which is the amount of income associated with the nonresident individual's adjusted federal tentative minimum tax that is derived from or connected with sources within this state, as such phrase is defined in sections 12-711 and 12-713, and the denominator of which is the amount of income associated with the nonresident individual's adjusted federal tentative minimum tax that is derived from or connected with sources within and without this state. The provisions of this subsection shall apply to nonresident trusts and estates, as defined in said section 12-701, and, wherever reference is made in this section to nonresident individuals, such reference shall be construed to include nonresident trusts and estates, provided any reference to a nonresident individual's Connecticut adjusted gross income shall be construed, in the case of a nonresident trust or estate, to mean the nonresident trust or estate's Connecticut taxable income.

# (c)

Every part-year resident individual, as defined in said section 12-701, subject to and required to pay the federal alternative minimum tax under Section 55 of the Internal Revenue Code shall pay, in addition to the tax imposed under section 12-700, the net Connecticut minimum tax, as calculated herein. The tax shall be the difference computed by subtracting the tax imposed under subsection (c) of section 12-700 from the product of the part-year resident individual's Connecticut minimum tax, as provided in subdivision (26) of subsection (a) of section 12-701, multiplied by a fraction, the numerator of which is the amount of income associated with the part-year resident individual's adjusted federal tentative minimum tax derived from or connected with sources within this state, as such phrase is defined in section 12-717, and the denominator of which is the amount of income associated with the part-year resident individual's adjusted federal tentative minimum tax that is derived from or connected with sources within and without this state. For the purposes of such calculation, the provisions of subsection (c) of said section 12-717 providing for the accrual of items of income, gain, loss or deduction shall apply to the calculation of the part-year resident individual's adjusted federal tentative minimum tax. The provisions of this subsection shall apply to part-year resident trusts, as defined in said section 12-701, and, wherever reference is made in this section to part-year resident individuals, such reference shall be construed to include part-year resident trusts, provided any reference to a part-year resident individual's Connecticut adjusted gross income shall be construed, in the case of a part-year resident trust, to mean the part-year resident trust's Connecticut taxable income.

# (1)

For taxable years beginning on or after January 1, 1994, a credit shall be allowed as provided herein in an amount equal to the excess, if any, of the adjusted net Connecticut minimum tax imposed for all prior taxable years beginning on or after January 1, 1993, over the amount allowable as a credit under this subsection for such prior taxable years.

# (2)

The credit allowable for a taxable year under this subsection is limited to the amount, if any, by which (A)(i) the tax imposed under section 12-700, (ii) less the credit, if any, allowed under section 12-704 exceeds (B)(i) the Connecticut minimum tax, determined without regard to whether the individual or the trust or estate is subject to and required to pay for that taxable year the federal alternative minimum tax under Section 55 of the Internal Revenue Code, (ii) less the credit, if any, allowed under subsection (e) of this section.

# (e)

A resident or part-year resident shall be allowed a credit against the tax otherwise due under this section in the amount of any similar tax imposed on such resident or part-year resident for the taxable year by another state of the United States or a political subdivision thereof or the District of Columbia on income which is derived from sources therein and which is also subject to tax under this section. In the case of a resident, the credit provided under this subsection shall not exceed the proportion of the tax otherwise due under this section that the amount of the taxpayer's adjusted federal tentative minimum tax derived from or connected with sources in the other taxing jurisdiction, as the phrase is used in section 12-704, bears to the taxpayer's adjusted federal tentative minimum tax. In the case of a part-year resident, the credit provided under this subsection shall not exceed the proportion of the tax otherwise due during the period of residency that the amount of the taxpayer's adjusted federal tentative minimum tax derived from or connected with sources in the other taxing jurisdiction, as the phrase is used in said section 12-704, during the period of residency bears to such taxpayer's adjusted federal tentative minimum tax during the period of residency, nor shall the allowance of the credit provided under this subsection reduce the tax otherwise due under this section to an amount less than what would have been due if the amount subject to similar taxation by such other jurisdiction were excluded in the calculation of the adjusted federal tentative minimum tax.
