Estate administration expenses are deductible when they meet three tests set by federal regulation: the cost must be necessary to collect the estate’s assets, pay its debts, or distribute property to the right people; it must actually be incurred, not estimated; and the amount must be reasonable for the work performed. Meet all three and the executor can claim the expense, either against the taxable estate on Form 706 or against the estate’s income on Form 1041. The choice matters, because the same dollar cannot be deducted twice.
The Three-Part Test Under 26 CFR 20.2053-3
Necessary means the expense benefits the estate as a whole, not one heir’s personal position. If a beneficiary hires counsel to fight another beneficiary over a specific asset, those fees fail the test even when the probate court signs off on reimbursement.
Actually incurred means a bill exists or a legal obligation to pay has arisen. Projected future costs do not qualify.
Reasonable is judged against the estate’s size, local custom, and the expertise the work required. Probate courts can trim fees they find excessive, and the IRS can independently disallow any portion it considers unreasonable, regardless of what the court approved. The three standards work together: a necessary, incurred, but inflated expense is allowed only up to a reasonable amount, and a reasonable fee for a service the estate did not need fails at step one.
What Executors Can Deduct
Executor Compensation
The executor’s fee is usually the single largest administration expense. The amount depends on the will’s terms or, if the will is silent, state default rules. Some states use a sliding-scale percentage of gross estate value, some tie the fee to cash flowing through the executor’s hands, and some allow reasonable compensation based on hours and complexity. Fees generally land between 1% and 5% of the gross estate. Two limits are worth flagging: if no fee is actually paid, nothing is deductible, and a bequest left to the executor in place of a commission is not deductible either.
Attorney, Accounting, and Appraisal Fees
Attorney fees for probating the will, retitling assets, resolving creditor claims, and handling disputes essential to settlement are deductible up to a reasonable amount. Fees for litigation among beneficiaries over their respective shares do not qualify unless the litigation is essential to settling the estate itself.
Accounting fees cover the decedent’s final individual return, the estate’s Form 1041 fiduciary return, and the Form 706 estate tax return. Appraisal fees establish date-of-death fair market values, which drive both the estate tax calculation and the stepped-up basis beneficiaries inherit.
Court Costs and Publication Fees
Probate filing fees and the cost of publishing notice to creditors in a local newspaper are deductible. Individually modest, they accumulate across a multi-year administration.
Maintaining and Preserving Property
Utility bills, insurance premiums, property taxes accruing after death, storage fees, and necessary repairs on estate property are deductible while the executor reasonably needs to hold the asset. Two limits apply. Improvements and additions do not count. And an executor who drags out a sale without justification can lose the carrying costs for the excess period.
Selling Estate Assets
Brokerage commissions, auctioneer fees, title insurance, and transfer taxes on sales of estate property are deductible when the sale is necessary to pay debts, cover administration expenses, pay taxes, preserve the estate, or complete distributions. Selling an asset only because a beneficiary prefers cash may not qualify. The sale must serve a real settlement purpose.
What Executors Cannot Deduct
- Costs that serve a single beneficiary’s personal interest rather than the estate’s settlement, even when reimbursed by court order.
- Capital improvements. Replacing a broken furnace is a repair and is deductible. Adding a new deck is an upgrade and is not.
- Income taxes on income the estate earns after death, and property taxes that had not accrued before death.
- Bequests left to the executor in place of a formal commission.
- Preservation costs for any period beyond what the administration reasonably required.
- Expenses allocable to tax-exempt income, such as costs tied to a municipal bond portfolio. These are not deductible on Form 706 or Form 1041.
The IRS applies these limits independently of the probate court. A locally approved expense can still be disallowed on the federal return if it fails the federal standard.
Deducting on Form 706 vs. Form 1041
The same administration expense can reduce the taxable estate on Form 706 or reduce the estate’s taxable income on Form 1041. Federal law prohibits taking both. Choosing between them is the executor’s most consequential tax decision on these costs.
When Form 706 Wins
Deducting on Form 706 lowers the taxable estate and reduces the 40% federal estate tax. For 2026, the basic exclusion amount is $15,000,000 per person, and only value above that threshold is taxed. If the estate exceeds the exemption, each deductible dollar saves up to 40 cents in estate tax. For large taxable estates, Form 706 is almost always the right home for the deduction.
Below the exemption, Form 706 produces zero benefit. There is no estate tax to reduce.
When Form 1041 Wins
For estates that owe no estate tax, deducting against income on Form 1041 is usually the better move. Estates and trusts hit the top 37% federal income tax rate at just $16,000 of taxable income in 2026, so even modest deductions produce real savings.
To use Form 1041, the executor files a waiver with the return giving up the right to claim those same expenses on Form 706. The waiver must be filed before the statute of limitations expires for the tax year involved. A single expense cannot be split between the two returns, but different expenses can go to different returns. Attorney fees might be claimed on Form 706 while accounting fees go on Form 1041.
Comparing the Rates
The straight math favors Form 706 at 40% over Form 1041 at 37% when both are available. Near the exemption boundary the answer can flip. An estate generating significant rental income, interest, or capital gains during administration may extract more value from the Form 1041 deduction even when the estate technically owes some estate tax.
One downstream effect: expenses claimed on Form 1041 reduce the estate’s distributable net income, which lowers the taxable income passed through to beneficiaries on Schedule K-1. The income tax savings can reach the heirs, not just the estate.
Which Schedule on Form 706
Form 706 splits administration expenses between two schedules based on whether the underlying property passes through probate.
Schedule J handles funeral expenses and the administration expenses of property subject to creditor claims. Most probate costs live here: executor fees, attorney fees, court costs, and the costs of maintaining or selling probate assets.
Schedule L handles administration expenses tied to property included in the gross estate but not subject to claims. Revocable trust assets are the common example. They belong in the taxable estate but bypass probate, so expenses for collecting, clearing title to, or transferring them go on Schedule L. Expenses claimed on Schedule L must be paid before the statute of limitations on assessment expires.
Putting an expense on the wrong schedule does not automatically lose the deduction, but it invites IRS questions and slower processing.
Deadlines That Can Lock Out a Deduction
Form 706 is due nine months after the date of death. An automatic six-month extension is available on Form 4768, which extends filing but not necessarily payment. Missing the filing window can forfeit certain deductions entirely.
Form 1041 is filed for each tax year the estate earns income. The waiver required to shift administration expenses from Form 706 to Form 1041 must be filed before the statute of limitations closes for the tax year in question. Once a deduction is taken on Form 706 or a waiver is filed on Form 1041, that choice is permanent for the specific expense.
Documentation the IRS Will Ask For
Every deducted expense needs a paper trail. Receipts, invoices, bank statements, and contracts should be retained for each payment. The IRS can request substantiation for any deduction on Form 706 or Form 1041, and an undocumented expense is one waiting to be disallowed.
The cleanest approach is to open a dedicated estate bank account at the start and route every transaction through it. That produces a single ledger and prevents commingling with personal funds. For complex estates, engaging a bookkeeper or CPA from day one costs less than reconstructing records later. Incomplete records also shift the burden of proof to the executor if a beneficiary challenges a payment, and an unexplained expenditure can be surcharged against the executor personally.
