Limitations where credit is claimed for income taxes paid

# (a)

When a state of the United States imposes an income tax on income derived from sources within such state and one or more of its political subdivisions imposes income tax on the same income (or a portion thereof), the amount of the credit against Connecticut income tax for income taxes paid to that state and its political subdivision(s) is subject to the limitations provided in subsections (b), (c), (d) and

(e) of this section and in § 12-704(c)-1 of this Part. When a state does not impose an income tax on income derived from sources within such state but two or more of its political subdivisions impose an income tax on income derived from sources within those respective political subdivisions, the amount of the credit against Connecticut income tax on income taxes paid to those political subdivisions is subject to the limitations provided in § 12-704(a)-2 of this Part (and not to the limitations provided in this section).

# (b)

Except as further limited by subdivision (3) of subsection (c) of this section, the credit for income tax paid to another state and its political subdivision(s) cannot exceed the total of the income taxes paid to those qualifying jurisdictions.

# (c)

# (1)

The credit for income tax paid to another state and its political subdivision(s) cannot exceed the proportion of the Connecticut tax liability that is described in this subsection.

# (2)

Where the amount of income subject to tax in another state is equal to (and not more or less than) the amount of income subject to tax in a political subdivision of such state, that common amount of income is to be included only once in the numerator, and the credit for income tax paid to a state and its political subdivision cannot exceed the proportion of the Connecticut tax liability that the common amount (the numerator) bears to the taxpayer's Connecticut adjusted gross income (the denominator).

# (3)

Where the amount of income subject to tax in another state is not equal to (but is more or less than) the amount of income subject to tax in a political subdivision of such state, the credit for income tax paid to a state and its political subdivision cannot exceed the aggregate limitation described in subparagraphs (A) and (B) of this subdivision.

(A) With respect to the common amount subject to tax in both the other state and a political subdivision of such state (the common amount), the credit for income tax paid on the common amount cannot exceed the proportion of the Connecticut tax liability that such common amount (the numerator) bears to the taxpayer's Connecticut adjusted gross income (the denominator). For purposes of the limitation provided in subsection (b) of this section, the income tax considered to have been paid to the qualifying jurisdiction in which the larger amount of income is subject to tax (the larger income jurisdiction) on the common amount is that percentage of the income tax actually paid to the larger income jurisdiction that the common amount bears to the amount of income subject to tax in the larger income jurisdiction.

Income Tax

(B) With respect to the amount in excess of such common amount (the excess amount), the credit for income tax paid on the excess amount cannot exceed the proportion of the Connecticut tax liability that such excess amount (the numerator) bears to the taxpayer's Connecticut adjusted gross income (the denominator). (For purposes of the limitation provided in subsection (b) of this section, the income tax considered to have been paid to the larger income jurisdiction on the excess amount is that percentage of the income tax actually paid to the larger income jurisdiction that the excess amount bears to the amount of income subject to tax in the larger income jurisdiction.)

# (d)

If a taxpayer is required, under § 12-704(a)-2(d), to add back to Connecticut adjusted gross income a net loss derived from or connected with sources within a qualifying jurisdiction, the same addback shall be made in calculating the credit limitation under subsection (c) of this section.

# (e)

The credit for income tax paid to another state and its political subdivision(s) cannot exceed the Connecticut tax liability.
