IRS Material: Taxes - Estate
Pub 529 and Pub 17
Excess Deductions of an Estate If the total deductions in the estate's last tax year are more than the estate's gross income for that year, the beneficiaries succeeding to the estate's property can claim such excess as a miscellaneous deduction. Do not include deductions for personal exemption and charitable contributions when figuring the total deductions. The beneficiaries can claim the deduction only for the tax year in which or with which the estate terminates, whether the year of termination is a normal year or a short tax year.
