The estate tax exemption is never really permanent. Sen. Elizabeth Warren (D-MA) introduced a bill into the Senate this week to address our national housing crisis. She wants to spend about $500 billion in affordable housing programs over the next ten years. She plans to pay for this by taxing estates like they were during the George W. Bush administration.
In 2001 the estate tax exemption amount was $675,000 and everything over that was taxed at 55%. By 2009 it had risen to $3.5 million with a tax rate of 45% on everything over that.
