NOTE: Estate tax planning involves the comparison between the estate tax rate and the federal and state income tax rate. When the estate tax rate was 50% or higher, the financial advantage of eliminating estate taxes was clear; with the tax rates now roughly the same, the rationale for estate tax planning has greatly diminished.
NOTE: For collectibles (artwork, jewelry, antiques), the federal income tax rate is 28%, so for these items, the combined federal and state income tax rate may actually be higher than the federal estate tax rate.
