For purposes of this chapter, the term “taxable termination” means the termination (by death, lapse of time, release of power, or otherwise) of an interest in property held in a trust unless—

If, upon the termination of an interest in property held in trust by reason of the death of a lineal descendant of the transferor, a specified portion of the trust’s assets are distributed to 1 or more skip persons (or 1 or more trusts for the exclusive benefit of such persons), such termination shall constitute a taxable termination with respect to such portion of the trust property.

The term “direct skip” means a transfer subject to a tax imposed by chapter 11 or 12 of an interest in property to a skip person.

Solely for purposes of determining whether any transfer to a trust is a direct skip, the rules of section 2651 (f)(2) shall not apply.
