Spouses often work together to build wealth for themselves and their children. Congress recognized this by enacting the gift and estate tax portability election as part of the 2010 Taxpayer Relief, Unemployment Insurance Reauthorization, and Job Creation Act and making it permanent in the American Taxpayer Relief of 2012, providing married couples with a relatively simple way to potentially shield much more of their wealth from federal gift and estate taxation. If you have recently lost your spouse, it is important to consider whether you should take advantage of the portability election.
What Is Portability of the DSUE?
In 2023, the federal estate tax exclusion amount is $12.92 million for individuals and $25.84 million for married couples, and only gross estates that exceed these amounts are subject to estate tax. Due to the unlimited marital deduction, married couples with large estates are usually able to avoid estate taxes at the death of the first spouse. However, at the death of the surviving spouse, their estate, including the amount that they inherited from their spouse, will be subject to estate taxes if the gross estate of the second spouse to die exceeds the estate tax exclusion amount. Prior to the enactment of the portability election in 2010, in the absence of complex planning, for example, forming a credit shelter trust with the deceased’s accounts and property equal to their remaining lifetime exclusion amount, the unused exclusion amount of the first spouse to die was lost, meaning that the couple’s children would inherit less of the couple’s wealth at the second death because only the second to die’s remaining lifetime exclusion amount was available to reduce the estate tax that had to be paid. The portability election allows the surviving spouse to add the deceased spouse’s unused exclusion (DSUE) amount to their own exclusion amount to reduce or eliminate estate tax liability when they die.
How Do You Elect Portability?
To take advantage of portability of the DSUE amount, after one spouse dies, the surviving spouse must file an estate tax return (Form 706) and make a portability election that allows the DSUE amount to be applied to the surviving spouse’s subsequent transfers during life or at death. Portability must be elected properly or it will be ineffective, so it is important to seek the help of a tax professional. If the deceased spouse’s gross estate exceeds the basic exclusion amount ($12.92 million), a federal estate tax return must be filed within nine months of the date of death (although a sixmonth extension is available). To take advantage of the DSUE amount, the executor of the deceased spouse’s estate must elect portability and compute the DSUE amount on the timely estate tax return. No extension of time to elect portability is available in this situation.
