Perhaps no section of the tax code does as much societal damage while generating relatively little revenue as the estate tax.
Estate taxes generate less than one percent of federal revenues.
Estate tax compliance costs the economy almost as much as the revenue raised. Such compliance costs are a deadweight loss to society. High marginal estate tax rates also discourage savings and investment, reducing economic growth. Further, there is neither social nor economic justification for the estate tax. Estate taxes today are far out of line with historical precedent.
