Tax Foundation, The Estate Tax: Even Worse Than
Republicans Say:

A recent study issued by the Republican staff of Congress’ Joint
Economic Committee detailed many of the failings of the estate tax,
calling for either a significant reform or outright repeal of the estate
tax. The report, which referenced four separate Tax Foundation studies
and testimonies, reached similar conclusions to those which Tax
Foundation analysts have reached with regard to the estate tax.

This new analysis, however, strengthens the case for repeal with
additional evidence of the compliance burdens inherent to the estate
tax. These costs are larger than is often understood, so much so that
tax revenue is likely to actually increase upon repeal in the coming
years.

Research has indicated that income and capital gains tax revenues
will increase significantly if the estate tax is repealed even without
an increase in economic growth. Several articles have found that repeal
would be revenue neutral over all, or even revenue positive, over a 10
year period if both the tax changes and economic growth are considered
together.
