This course will provide tax advisers with a comprehensive guide to the computation and reporting of the deceased spouse's unused exclusion change to the deceased spouse's unused exemption (DSUE). The panel will explain when portability should be elected and demonstrate the calculation to show the DSUE amount transferred from the deceased spouse to the surviving spouse.


Portability is a game-changer in estate planning. Whether the federal estate tax basic exclusion amount reverts in 2026 to $5,000,000 as adjusted for inflation under current law or the proposed anti-clawback regulations are enacted, ensuring that the unused exclusion of the first spouse to die can be used by the surviving spouse (or surviving spouse's estate) is a critical part of planning for married couples. Determining the DSUE amount involves complex and critical calculations. When a federal estate tax return is filed for the first spouse, the tax preparer makes the portability election.

The portability regulations require the executor of a decedent's estate to calculate the DSUE and report the amount on the estate tax return to elect portability for the surviving spouse. The regulations define the DSUE amount and prescribe a multi-step process for calculating the unused exemption amount.

The key for tax and estate advisers to remember is that portability is not automatic--the executor must elect it. The election requires filing a Form 706, U.S. Estate Tax Return to report the DSUE amount, even when filing an estate return may not be necessary. The surviving spouse can utilize the DSUE of the deceased spouse as an additional gift or estate tax exclusion. Missing the election to port an exemption can prove costly. Revenue Procedure 2017-34 offers relief for certain untimely elections.

Listen as our experienced panel provides detailed and practical guidance on calculating DSUE amounts and dealing with missed elections, discusses the planning opportunities, and offers illustrations on how to report those amounts on Form 709.
