On July 14, 2008, the IRS released T.D. 9414, which addressed the valuation for federal estate tax purposes of a retained interest in certain trusts. The trusts affected include charitable remainder annuity trusts, charitable remainder unitrusts, grantor retained annuity trusts, grantor retained income trusts, grantor retained unitrusts, qualified personal residence trusts and personal residence trusts. In effect, the IRS concluded that, under §2036, the amount includible in the grantor's estate if he or she dies during the term of one of the foregoing types of trust is limited to the value of the remaining retained annuity or unitrust interest, which is not necessarily (although it may be), equal to the value of the entire corpus.
