(a) To the amount of items of income, gain, loss and deduction that enter into the definition of distributable net income there shall be added or subtracted, as the case may be, the modifications to federal taxable income described in this chapter to the extent they relate to items of income, gain, loss and deduction that also enter into the definition of distributable net income. No modification shall be made under this section that has the effect of duplicating an item already reflected in the definition of distributable net income.
(b) The amount determined under paragraph (a) of this subsection shall be allocated among the estate or trust and its beneficiaries (including, solely for the purpose of this allocation, resident beneficiaries) in proportion to their respective shares of federal distributable net income. The amounts so allocated have the same character as for federal income tax purposes. If an item entering into the computation of such amounts is not characterized for federal income tax purposes, it has the same character as if realized directly from the source from which realized by the estate or trust, or incurred in the same manner as incurred by the estate or trust.
(c) If the estate or trust has no federal distributable net income for the taxable year, the share of each beneficiary in the net amount determined under paragraph (a) of this subsection shall be in proportion to the beneficiary’s share of the estate or trust income for such year, under state law or the terms of the instrument, that is required to be distributed currently and any other amounts of such income distributed in such year. Any balance of such net amount shall be allocated to the estate or trust.
(2) The Department of Revenue may by regulation establish such other method or methods of determining the respective shares of the beneficiaries and of the estate or trust in its income derived from sources in this state, and in the modifications related thereto, as may be appropriate and equitable.
