Wisconsin's Estate Tax Laws
Wisconsin does not collect an estate tax at the state level. However, things were different before major changes took effect with regard to federal estate tax laws. What do federal estate tax laws have to do with Wisconsin estate taxes? Prior to January 1, 2005, Wisconsin actually did collect a separate estate tax at the state level, called a "pick up tax," that was equal to a portion of the overall federal estate tax bill.
What Is the Pick Up Tax?
The "pick up tax" is a state estate tax that is collected based on the state estate tax credit that the IRS allowed on the federal estate tax return, IRS Form 706, prior to January 1, 2005. Each state had different tax laws with regard to the pick up tax, so the amount that a state would collect varied based on that state's own estate tax laws. In essence, however, the overall estate tax bill was not increased or decreased due to the pick up tax. Instead, the total tax bill was apportioned between the IRS and state taxing authority.
In plain English, this means that a portion of the federal estate tax was actually taken away from the IRS and instead paid to the decedent's state taxing authority. As such, prior to January 1, 2005, if a deceased Wisconsin resident owed federal estate taxes, then the Wisconsin Department of Revenue collected the pick up tax from the deceased Wisconsin resident's estate.
The Future of the Wisconsin Estate Tax
Effective January 1, 2005, the pick up tax was officially phased out under the provisions of the Economic Growth and Tax Relief Reconciliation Act ("EGTRRA"). In response to these changes in federal law that phased out the pick up tax, some states that used to collect a pick up tax chose to enact laws that allow the state to still collect a state estate tax. This is referred to as "decoupling" since the states that enacted a state estate tax no longer based their state estate tax laws on current federal estate tax laws.
The majority of states did absolutely nothing and therefore no longer collect a state estate tax. Wisconsin was among the minority and did enact a separate state estate tax but then ended up repealing it effective January 1, 2008. In addition, under the provisions of EGTRRA the pick up tax was supposed to return in 2011, but the Tax Relief Act of 2010 did not include reinstatement of the pick up tax. So, even if the federal law is changed to allow the pick up tax to come back in the future, Wisconsin will not be able to collect a pick up tax unless the Wisconsin legislature reinstates Wisconsin pick up tax laws.
