(2) The respective shares of an estate or trust and its beneficiaries (including, solely for the purpose of this allocation, nonresident beneficiaries) in the fiduciary adjustment shall be in proportion to their respective shares of federal distributable net income of the estate or trust. If the estate or trust has no federal distributable net income for the taxable year, the share of each beneficiary in the fiduciary adjustment shall be in proportion to the share of the estate or trust income of the beneficiary 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 the fiduciary adjustment shall be allocated to the estate or trust.
(3) The Department of Revenue may by rule authorize the use of such other methods of determining to whom the items comprising the fiduciary adjustment shall be attributed, as may be appropriate and equitable, on such terms and conditions as the department may require.
