Taxability of Potential Inheritance
DH's stepmother is 83. She recently changed ownership of her accounts (savings, brokerage) to herself, jointly with DH. She has written, notarized instructions to DH as to where the money goes after her death (split among the grandchildren, with remainder to us). She also has an IRA with DH as sole beneficiary. My question is: what is the taxability to all involved?
