Description: In this article, the author discusses an estate planning strategy that is extremely effective in an environment of low interest rates and depressed asset values, and was made more attractive by the December 17, 2010 legislation that provides extensive estate tax relief, although only for two years: the Grantor Retained Annuity Trust or GRAT. The articles discusses how a GRAT works, strategy for setting one up, income tax considerations, certain drawbacks, and the need to act quickly, given congress is considering legislation that would impose restrictions.
