Estate Administration Expenses: Estate Tax Deduction or Income Tax Deduction?

Some administration expenses sit at the intersection of estate tax and fiduciary income tax.

Two systems

Certain administration expenses can potentially be deductible in computing the taxable estate or on the estate's fiduciary income-tax return, depending on the rules and election.

No double benefit

The same expense generally cannot be deducted twice across both systems.

Planning effect

The better location can depend on whether the estate owes estate tax and the estate's income-tax position.

Exam strategy

Ask which tax system the question is testing and whether the facts permit or require a choice.

The takeaway

Estate administration expenses can involve a deduction choice, but the same expense generally cannot create both an estate-tax and income-tax deduction.
