(1) Where the ordinary income portion (or part thereof) of a lump sum distribution is subject to separate income taxation by another state of the United States, a political subdivision of such state, the District of Columbia, or a province of Canada, the amount of separate tax imposed on such income by such jurisdiction (reduced by any applicable credits of such jurisdiction, exclusive of prepayments) is the amount which constitutes the income tax imposed on the ordinary income portion (or part thereof) of a lump sum distribution by such other jurisdiction.
(2)Where such ordinary income portion (or part thereof) of a lump sum distribution is not subject to separate income taxation by such other taxing jurisdiction, but is included as income in determining the income tax imposed by such jurisdicti#
(2) Where such ordinary income portion (or part thereof) of a lump sum distribution is not subject to separate income taxation by such other taxing jurisdiction, but is included as income in determining the income tax imposed by such jurisdiction, the portion of such income tax which constitutes the income tax imposed on the ordinary income portion (or part thereof) of a lump sum distribution is determined by multiplying the entire income tax payable to the other taxing jurisdiction by a fraction, the numerator of which is the ordinary income portion (or part thereof) of the lump sum distribution included in the income subject to tax by such jurisdiction and the denominator of which is all the income subject to such tax by such jurisdiction. See sections 120.1 through 120.5 of this Part for the resident credit allowable against ordinary tax for the balance of the income tax imposed by such other taxing jurisdiction which does not constitute the income tax imposed on the ordinary income portion (or part thereof) of a lump sum distribution.
