## Abstract

This document contains final regulations revising the definition of income under section 643(b) of the Internal Revenue Code. The regulations are necessary to reflect changes in the definition of trust accounting income under state laws. The final regulations also clarify the situations in which capital gains are included in distributable net income under section 643(a)(3). Conforming amendments are made to regulations affecting ordinary trusts, pooled income funds, charitable remainder trusts, trusts that qualify for the gift and estate tax marital deduction, and trusts that are exempt from generation-skipping transfer taxes. The regulations affect the grantors, beneficiaries, and fiduciaries of trusts.
