Sorry for your loss, but unfortunately, funeral expenses cannot be claimed as an income tax deduction. If the value of your husband’s estate was large enough to require the filing of a federal estate tax return, then funeral expenses can be deducted on that return, Form 706.
A capital loss that is not deductible because it exceeds the annual $3,000 capital loss ceiling. A carryover loss may be deducted from capital gains of later years plus up to $3,000 of ordinary income.
