I. Introduction

- A grantor retained annuity trust (GRAT) or an installment sale to a grantor trust can be useful in transmitting wealth in a tax-efficient way, and often one of these techniques is superior to other estate planning options. These are in effect estate freeze techniques that capitalize on the mismatch between interest rates used to value transfers and the actual anticipated performance of the transferred asset. Sales to grantor trusts and many GRATs also capitalize on the lack of symmetry between the income tax rules governing grantor trusts and the estate tax rules governing includibility in the gross estate. Like most techniques, GRATs and sales to grantor trusts can be used conservatively, aggressively, or even recklessly, and some of the tax consequences are unclear. Moreover, like most techniques, their availability and usefulness must be evaluated on a case-by-case basis, with a view to the circumstances, and especially the arithmetic, in each case.
