As discussed in greater detail in this Asbury Park Press article, various New Jersey state legislators are taking a variety of positions on modifying New Jersey's death tax regime. "Death tax" is a reference to the two types of taxes potentially applicable to New Jersey residents when they die: an estate tax applied to estates valued in excess of $675,000; and an inheritance tax levied in certain situations based on the relationship of the decedent to the recipient of the decedent's assets.
As stated in the article, "No state in the nation levies taxes when people die as aggressively as New Jersey." Different bills have been proposed in recent years -- for instance, raising the estate tax exemption amount beyond the current $675,000 or repealing death taxes altogether -- but none have gained much traction. The difficulty is largely summed up in the following sentence from the article: "The current budget counts on a record $758 million from the estate and inheritance taxes combined."
