IRS rules generally exclude compensatory damages for personal physical injuries or sickness from gross income. Wrongful death proceeds tied to those injuries usually follow that rule — with important exceptions.
There is no chart and no average. The heirs' claim is the support and the care the family lost, plus funeral costs. The decedent's own pain belongs to a different case, brought by the estate.
Not every grieving relative is a plaintiff. California names who may bring a wrongful death case, requires the heirs to proceed together, and treats the estate's claim for the decedent's own losses as a separate lawsuit.
