For
decedents dying in 2010-2012, the amount that can be transferred
at death
free of estate tax, known as the basic exclusion amount,
is $5 million, as indexed for inflation beginning in 2012.
In 2011 and 2012, a surviving spouse may use the “deceased
spousal unused exclusion amount” on top of the surviving
spouse’s own $5 million basic exclusion for taxable
transfers made during life or at death. This concept is commonly
referred to as portability. For the time
being, portability will not apply to decedents
dying
after 2012 and the exclusion amount for a surviving spouse
will again be limited to that surviving spouse’s own
exclusion amount.
Note
that a surviving spouse cannot take advantage of his or
her deceased spouse’s unused exclusion amount unless
the personal representative
of the deceased spouse’s estate files an estate tax return that calculates
the portable amount and makes a portability election. As a result, all personal
representatives of estates of deceased married persons should consider filing
federal estate tax returns, no matter how small the estate. This is because the
amount of the surviving spouse’s gross estate is unknown at the death of
the first spouse to die, and the surviving spouse could, for example, later win
the lottery or have substantial asset appreciation. The portability election
is irrevocable and cannot be made if the estate tax return of the deceased spouse
is filed after the due date (including extensions) for filing the return.
