If there had been a federal estate tax, you would have been entitled to a write-off for the federal estate tax with respect to the IRA. This is because the IRA is income in respect of a decedent (income earned by the person before death that is taxed to someone else after the person’s death). However, since there was no estate tax, you don’t get any deduction.
The legal transfer of property, rights, or interest to another person called an assignee. You cannot avoid tax on income by assigning the income to another person.
