Answer:
$475,000
Step-by-step explanation:
we know that as by estate taxes 2019 and
that estate of a single individual is over 11.4 million dollars
or estate of a married couple is over 22.8 million dollars.
that is change by 2017 Tax Cuts and Jobs Act because Before threshold was very lower
so here as of the 2017 Tax Cuts and Jobs Act
the full $1,600,000 estate is not subject to taxes
so full amount is transfer with no tax implications to whomever with no tax implication
but here died year is not given so if we consider he died before than
Maritable deduction is available unlimited if transferred by a deceased spouse to the survivor spouse both being US citizen
and in the case Alans estate should claim a marital deduction of $475,000 in computing the taxable estate
