successive income beneficiary
(i) If the income beneficiary of a QSST who made a QSST election dies, each successive income beneficiary of that trust is treated as consenting to the election unless a successive income beneficiary affirmatively refuses to consent to the election. For this purpose, the term successive income beneficiary includes a beneficiary of a trust whose interest is a separate share within the meaning of section 663(c), but does not include any beneficiary of a trust that is created upon the death of the income beneficiary of the QSST and which is a new trust under local law.
