Everyone is talking about the lack of  a Federal estate tax this year, but as this  New York Times article points  out, there are still 20 states that levy a local estate tax. It explains  how state estate taxes can complicate the process of dealing with a  recently deceased family member’s finances, and provides advice on  how to plan for local estate taxes. 
The first quarter is nearly over, and  the federal government has made no move to reinstitute the estate tax.  So dying today seems free, right?
There is just one problem: If you live  in one of 20 states with a state estate tax, you could find your existing  estate tax plans causing more harm than good.
State estate taxes are not new. They  had just been a secondary element in the course of figuring out the  much higher federal estate tax.
Now, the issue is sorting through wills  written to maximize the old federal exemption from estate taxes —  $3.5 million in 2009. In states with their own estate taxes, some of  these provisions could distribute money and incur taxes in ways the  deceased never expected — or maybe not if the federal estate tax is  reinstated. As Jerry Weihs, director of advanced planning at Sun Life  Financial, said: “We’re in a state of ambiguity.”
 
AUTOMATIC MISTAKES 
 
The biggest issue with the state estate  taxes is wills that contain so-called formula clauses. Many wills were  redrafted in the last decade to take into account the increasing federal  estate tax exemption. Instead of rewriting the will every few years,  clauses were put in to reflect the rising exemption amount.
