Frequently asked questions
Do most estates owe federal estate tax?
No — the federal exemption is quite high, so the large majority of US estates fall below the threshold and owe nothing.
Do states have their own estate or inheritance taxes?
Some states levy separate estate or inheritance taxes with much lower exemption thresholds — check your state's rules.
Is this a flat 40% on the whole estate?
No — the rate applies only to the portion of the estate above the exemption, similar to marginal income tax brackets in concept.
