The Senate Budget Committee has reported out a budget which includes includes $80.6 billion in tax cuts which would have reconciliation protection. Of this, around 3 billion is for repeal of the estate tax in 2009. The low cost figure is likely due to the fact that most of the revenue effects would take place outside of the 5 year budget window in 2010. The remaining $77 billion is used for the 3 "middle class" tax cuts - child credit, 10% bracket, and marriage penalty.
