The Center on Budget & Policy Priorities has published Berkley Estate Tax Bill Would Add Billions to Deficit While Benefiting Only Wealthiest 1 in 500 Estates:

A new estate tax bill introduced by Representative Shelley Berkley (D-NV) and others would cost $119 billion more over the first decade (2012-2021) than extending the tax under its current rules as the President has proposed, yet would benefit only the nation’s wealthiest 0.2 percent of estates since they are the only ones subject to the tax under the current rules. In subsequent decades, the Berkley proposal (H.R. 3905) would be even more expensive compared to extending the current estate tax rules; the proposal keeps its cost down in the initial years by phasing in its estate tax cuts over a decade, with its full costs not showing up until after 2019.
