Journal of Accountancy:  “In a letter to IRS Commissioner John Koskinen and other IRS officials on March 19, Troy Lewis, chair of the AICPA Tax Executive Committee, requested that the IRS provide relief to surviving spouses who want to elect portability of the deceased spouse’s unused estate tax exemption (DSUE) amount.  Sec. 2010(c) allows the surviving spouse of a decedent who dies after Dec. 31, 2010, to elect to use any amount of the deceased spouse’s estate tax exemption that was unused by the deceased spouse. This is commonly referred to as the portability election. The election must be made on a timely filed Form 706,  United States Estate (and Generation-Skipping Transfer) Tax Return, and must be made by the executor of the deceased spouse’s estate.”
