Legal fees paid to settle a decedent’s estate are generally tax deductible when they are necessary and reasonable for administering the estate. The deduction can be taken either on the federal estate tax return (Form 706) or on the estate’s fiduciary income tax return (Form 1041), but never on both for the same dollar of fees. Whether estate legal fees are tax deductible in your case, and which return to use, depends mainly on the size of the estate and who benefits from the legal work.
Which Legal Fees Qualify
Federal regulations define deductible administration expenses as those “actually and necessarily incurred” in collecting the decedent’s assets, paying debts, and transferring property to the people entitled to it.1eCFR. 26 CFR 20.2053-3 – Deduction for Expenses of Administering Estate Attorney fees fit that definition, provided the amount is reasonable given the size of the estate, the complexity of the work, and local fee norms.
The legal work that typically qualifies includes:
- Probate court filings and appearances
- Identifying, marshaling, and valuing the decedent’s assets
- Negotiating with and paying creditors
- Preparing the estate tax return and the estate’s income tax return
- Transferring real estate titles to beneficiaries
- Distributing funds and property to heirs
- Defending the estate against creditor claims or contesting an IRS tax deficiency1eCFR. 26 CFR 20.2053-3 – Deduction for Expenses of Administering Estate
The common thread is that the legal work has to serve the estate’s collective interest. Accountant fees, appraiser fees, court costs, and executor commissions follow the same rule and are deductible to the extent they are necessary for proper administration.2Internal Revenue Service.

Which Legal Fees Don’t Qualify
The line between deductible and non-deductible often comes down to who benefits. Expenses that are “not essential to the proper settlement of the estate” but are incurred “for the individual benefit of the heirs” don’t qualify.1eCFR. 26 CFR 20.2053-3 – Deduction for Expenses of Administering Estate
Will contests between beneficiaries are the classic example. When one heir sues another over who gets what, those legal fees belong to the individuals fighting, not to the estate. Even if a probate court approves reimbursement from estate funds, the IRS still treats the fees as non-deductible personal expenses.1eCFR. 26 CFR 20.2053-3 – Deduction for Expenses of Administering Estate By contrast, when the executor hires an attorney to defend the will’s validity in a fiduciary capacity, those fees protect the estate as a whole and are generally deductible. The test is whether the litigation preserves the estate or just reshuffles it among heirs.
Legal work tied to personal-use property, like a family home or personal belongings that aren’t producing income for the estate, faces strict limits and often looks personal rather than administrative to the IRS. And if an attorney advises a beneficiary on that beneficiary’s own tax liability or investment strategy, the estate can’t claim those hours; that work serves the individual.
The safest practice is to have the attorney itemize invoices by task. A single bill lumping estate administration together with personal beneficiary advice invites scrutiny, because the executor can’t show which hours served the estate. Probate attorneys usually structure their billing this way already.
Where to Claim the Deduction
Estate legal fees can be deducted in one of two places: on Schedule J of Form 706 (the federal estate tax return), or on Form 1041 (the estate’s fiduciary income tax return). Which return is available to you depends on the size of the estate.
Form 706, for Estates Over $15 Million
Form 706 must be filed only when the gross estate exceeds $15 million for deaths occurring in 2026.3Internal Revenue Service. Estate Tax That threshold reflects the increased basic exclusion amount enacted by the One, Big, Beautiful Bill Act, signed into law on July 4, 2025, which permanently raised the exemption and indexed it for inflation.4Internal Revenue Service. What’s New – Estate and Gift Tax
On Form 706, legal fees are reported on Schedule J, which has dedicated line items for attorney fees, accountant fees, and executor commissions. Each entry must be marked as estimated, agreed upon, or paid.5Internal Revenue Service. Schedule J (Form 706) – Funeral Expenses and Expenses Incurred in Administering Property Subject to Claims The fees reduce the taxable estate before the 40% top estate tax rate is applied.
Estates below $15 million won’t owe federal estate tax, and no Form 706 is required. For those estates, the Schedule J deduction is simply unavailable.
Form 1041, for Any Estate With Income Over $600
Most estates generate at least some income after death. Bank interest, dividends, rental payments, and retirement distributions keep arriving while the estate is open. Once that income exceeds $600 in a year, the executor must file Form 1041.6Internal Revenue Service. File an Estate Tax Income Tax Return The $600 bar is low enough that most estates with financial accounts will cross it.
Section 67(e) of the Internal Revenue Code lets estates deduct administration costs that wouldn’t have existed if the property were held by an individual rather than an estate.7Office of the Law Revision Counsel. 26 USC 67 – 2-Percent Floor on Miscellaneous Itemized Deductions Probate attorney fees are the textbook example: an individual holding the same bank account or rental property would never need a probate lawyer. That makes the fee unique to the estate and fully deductible on Form 1041.
This distinction carries weight because Congress permanently eliminated miscellaneous itemized deductions for individual taxpayers through the One, Big, Beautiful Bill Act.7Office of the Law Revision Counsel. 26 USC 67 – 2-Percent Floor on Miscellaneous Itemized Deductions Costs that an individual would also incur, like routine investment advisory fees or homeowners association dues, don’t qualify for the Section 67(e) carve-out and aren’t deductible on Form 1041 either.
You Can’t Deduct the Same Fee Twice
Federal law prohibits claiming the same legal fee on both returns. Section 642(g) is explicit: if an expense is deducted under Section 2053 on Form 706, it cannot also reduce income on Form 1041, and vice versa.8Office of the Law Revision Counsel. 26 USC 642 – Special Rules for Credits and Deductions To claim any fee on Form 1041, the executor must file a written statement waiving the right to ever take that specific deduction on Form 706. The waiver is irrevocable, so the decision on where to place each fee should be made deliberately.
Executors can split fees between the two returns. One invoice can go on Form 706 while a different invoice goes on Form 1041, as long as no single fee appears in both places. That flexibility allows some tax optimization when both returns apply, but it requires careful tracking and a separate waiver statement for every fee claimed on the income side.
How to Decide Which Return to Use
For estates below $15 million, there is no choice to make. No Form 706 is required, so Form 1041 is the only available vehicle, and the legal fees reduce the estate’s income tax bill.
For estates above the $15 million threshold that owe estate tax, the right choice depends on which return produces the bigger tax savings. The estate tax rate tops out at 40%. The estate’s income tax rate can reach 37% on income above $14,450. Where the estate has significant liability on both returns, the estate tax deduction usually wins on pure math. But when the estate has substantial income and modest estate tax exposure, the income tax deduction might save more.
Documentation the Executor Needs
Schedule J on Form 706 requires the executor to describe each expense and indicate whether the amount is estimated, agreed upon, or paid.5Internal Revenue Service. Schedule J (Form 706) – Funeral Expenses and Expenses Incurred in Administering Property Subject to Claims An estimated fee is acceptable when the final bill isn’t in yet, but the IRS may later ask for proof that the actual payment was reasonable. Keep detailed invoices showing the date, description of work, hours billed, and hourly rate for every attorney and professional the estate engages.
For fees claimed on Form 1041, keep the Section 642(g) waiver statement in the file as well. Without it, the IRS can disallow the income tax deduction on the theory that the estate might be double-dipping.
State Estate Taxes Are Separate
A handful of states impose their own estate or inheritance taxes with exemption thresholds far below the federal $15 million mark. In those states, legal fees may be deductible on the state estate tax return even when the estate is too small to require a federal filing. Whether a state allows the deduction, and how it calculates it, varies by jurisdiction. Executors in states with a separate estate tax should check the state revenue department’s rules rather than assume federal treatment carries over.
