I am the beneficiary of my fathers 401k. I am told there is something called a qualified disclaimer that I can do so that the 401k can be put in the estate account and split with my siblings, is there such a disclaimer and how would I go about doing this? If I do this will I be responsible for the taxes on this money or would the taxes come out of the estate when it is settled?

Patrick:

Yes, such a qualified disclaimer IS possible.

However, such a complex tax issue is not one to be answered on a tax forum. Go seek the advice of a qualified tax pro who has experience in both income and estate taxes.
