Estate tax changes

The Legislature has updated the filing threshold to align with the applicable exclusion amount based on the 2017 legislation. For returns filed on or after July 23, 2017, an estate tax return is not required to be filed unless the gross estate is equal to or greater than the applicable exclusion amount.
