26 USC 2612 - Taxable termination; taxable distribution; direct skip

(a) Taxable termination 

(1) General rule 
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

(2) Certain partial terminations treated as taxable 
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 trusts 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.
