Unfortunately, no. The fees were payable by the estate and deductible only by the estate. 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.
A revenue ruling is the Commissioner’s “official interpretation of the interpretation of the law” and generally is binding on revenue agents and other IRS officials. Taxpayers generally may rely on published revenue rulings in determining the tax treatment of their own transactions that arise out of similar facts and circumstances.
