Estate Tax Before Distributions: Filing, Valuation, and Beneficiary Records

Before distributing an estate’s remaining assets, the executor needs a defensible account of federal estate-tax obligations, filing elections, asset values, and reserves. Closing probate does not necessarily eliminate an unpaid federal tax claim.

The December 30, 2025 decision in Estate of Spenlinhauer v. Commissioner, T.C. Memo. 2025-134, sustained significant estate-tax adjustments and held the residuary beneficiary liable as a transferee within a limit based on property received. The executor and beneficiary were the same person. The court directed decisions under Rule 155, the procedure for computing the amounts resulting from its rulings; the notice amounts were not final judgment figures. Id., slip op. at 18. The decision is a reminder to keep those roles and their records distinct.

Establish the filing obligation and deadlines

Determine whether Form 706 is required for the particular estate under the law applicable at the decedent’s death. A filing obligation, extension, valuation election, and payment obligation require separate attention. Do not apply the exclusion amount from one historical estate to a current death.

In Spenlinhauer, the decedent died in 2005, and the extended return deadline was May 4, 2006. The executor filed in February 2017. The court rejected the alternate-valuation election as untimely and the claimed conservation-easement exclusion for separate reasons. Filing years later did not restore those choices. Id., slip op. at 3–4, 9–10.

Obtain valuations tied to the correct date

Keep deeds, ownership records, debt statements, appraisals, valuation assumptions, and prior offers or sales. Ask whether the appraisal values the property on the legally relevant date. A local assessment is not automatically the property’s federal estate-tax fair market value.

The court credited the IRS expert’s $5,815,000 date-of-death valuation of a commercial property rather than the executor’s reliance on a local assessment. It also examined evidence surrounding the sale of a closely held stock interest. The lesson is to reconcile valuation positions across probate filings, tax returns, correspondence, and the underlying transactions. Id., slip op. at 10–12.

Investigate family transfers and outstanding notes

A deed transferring title before death does not end the federal estate-tax inquiry if the decedent retained possession or enjoyment and did not receive adequate and full consideration. For family loans, preserve the signed note, amendments, actual payment records, interest calculations, and evidence that the parties treated the arrangement as a genuine debt.

In Spenlinhauer, the mother continued living in the transferred home. The note was later amended to cancel at death, and the claimed payments were unsupported. On that record, the court included the home under section 2036. It separately included another outstanding note whose claimed discharge lacked documentation. These are distinct asset-inclusion questions, not a rule that every family transaction fails. Id., slip op. at 12–14.

Separate estate expenses from a beneficiary’s personal costs

Keep invoices, payment evidence, the purpose of the expense, and documents explaining its relationship to administration. Payment alone does not establish that every legal bill is deductible by the estate. Fees for a beneficiary’s individual interests may be treated differently from expenses essential to collecting assets, paying debts, or settling the estate.

The court rejected unsupported executor’s commissions and attorney’s fees. It also rejected litigation fees it found were not necessary to proper settlement of the estate, notwithstanding some proof of payment. Id., slip op. at 14–15.

Document the distribution decision and tax reserve

Prepare a dated list of assets, debts, potential tax liabilities, proposed distributions, and the basis for any reserve. The appropriate amount depends on the estate; this case supplies no universal percentage. Obtain advice before transferring assets when a tax obligation is uncertain.

Section 6901 provides a collection procedure; a separate basis under applicable state law or equity is needed for transferee liability. Spenlinhauer applied Massachusetts law because the transfers occurred there. The estate had received no equivalent value and held no assets after the residue went to the executor-beneficiary. The opinion’s Massachusetts-law result must not be presented as a ruling applying California transfer law. Id., slip op. at 16–18.
