Estate planning fees are generally not tax deductible on your income tax return unless they are directly related to business assets or income-producing property. However, legal fees related to the administration of the estate, such as probate or estate tax issues, may be deductible on the estate’s tax return. You should consult with a tax professional or an estate planning attorney to understand how these rules apply to your specific situation.
