A closely watched dispute in the U.S. Tax Court is drawing attention to how grantor retained annuity trusts—commonly known as GRATs—are structured, valued, and administered.
In Elcan v. Commissioner, the IRS assessed approximately $614 million in gift tax and $123 million in penalties against a Tennessee couple. The combined amount exceeds $736 million.
The case does not establish that GRATs are invalid. It remains pending, and the taxpayers dispute the IRS’s conclusions. Nevertheless, it offers an important warning: sophisticated estate-planning strategies require careful administration, credible valuations, and detailed documentation throughout the life of the trust.
How a GRAT generally works
A GRAT is an irrevocable trust designed to transfer future appreciation to beneficiaries while the person establishing the trust retains a fixed annuity for a specified period.
- The grantor contributes assets to the GRAT.
- The GRAT makes scheduled annuity payments back to the grantor.
- The value of the retained annuity is calculated using the applicable federal Section 7520 interest rate.
- If the assets grow faster than that assumed rate, the remaining appreciation may pass to the beneficiaries with little or no additional gift tax.
GRATs are frequently funded with marketable securities or interests in closely held businesses expected to appreciate. Their effectiveness, however, depends on proper drafting, defensible valuation, accurate payments, and compliance with the governing trust documents and applicable tax regulations.
What happened in the Elcan case?
According to publicly available case summaries, Patricia Elcan created three two-year GRATs in 2018. The trusts were initially funded with approximately $687.5 million of interests in investment-holding entities.
The trust agreements reportedly gave the grantor a substitution power—the ability to exchange trust property for other property of equivalent value. Substitution powers are common in grantor trusts, but the way that power is exercised can be important.
The grantor subsequently exchanged trust assets and cash for personal promissory notes reportedly exceeding $853 million. Those notes were later returned, forgiven, or cancelled as part of satisfying the GRATs’ required annuity payments.
Two of the GRATs ultimately transferred more than $131 million to the remainder beneficiaries. The third reportedly did not leave a remainder.
- Approximately $614 million in additional gift tax
- Approximately $123 million in accuracy-related penalties
- More than $736 million in combined exposure
The taxpayers are contesting the assessment in the U.S. Tax Court.
What the official Tax Court docket shows
The official U.S. Tax Court docket for Elcan v. Commissioner, No. 3405-25, provides a more precise view of the case’s procedural history. As of October 9, 2026, the docket contains 41 entries and shows that the taxpayers’ motion for partial summary judgment has been fully briefed.
- March 14, 2025: The taxpayers filed a 65-page petition.
- July 9, 2025: The IRS filed a 16-page answer.
- October 1, 2025: The taxpayers filed a 58-page motion for partial summary judgment, supported by declarations of 45 pages and 10 pages.
- January 26, 2026: The IRS filed a 104-page response and a 747-page supporting declaration.
- March 5 and April 6, 2026: The taxpayers filed a 28-page reply, followed by the IRS’s 33-page sur-reply.
- July–August 2026: The parties submitted additional briefing concerning supplemental authority.
On March 27, 2026, the Court assigned the case—and specifically the partial-summary-judgment motion—to Judge Greaves for disposition. The public docket does not show a ruling on that motion through October 9, 2026. The dispute therefore remains pending and has not produced a precedential Tax Court decision.

Why is the IRS challenging the trusts?
The dispute centers on whether the grantor retained a “qualified interest” under Internal Revenue Code Section 2702.
The IRS contends that the way the annuity obligations were satisfied prevented the retained annuity interests from receiving qualified-interest treatment. Under that theory, the entire value originally transferred to the GRATs could be treated as a taxable gift without an offset for the value of the retained annuity.
The IRS has also advanced an alternative argument: even if the annuity interests qualified, the substitution of personal notes for trust assets may itself have resulted in taxable gifts.
The taxpayers argue that the applicable regulations prohibit a GRAT from issuing its own note to satisfy an annuity. In their view, those rules do not prohibit the use of a note issued by the grantor and received through a separate asset-substitution transaction.
The Tax Court has not yet resolved these competing positions. The case therefore should not be described as a final prohibition against GRATs or grantor notes.
Six planning lessons from the dispute
1. Proper drafting is only the beginning
A trust may be drafted correctly but still face problems if it is not operated consistently with its terms and applicable tax rules. Annuity payments, asset substitutions, trustee decisions, valuations, and related-party transactions should be reviewed throughout the trust term—not merely when the trust is created.
2. Valuation affects more than the initial tax return
When a GRAT is funded with a closely held business interest, the initial valuation helps determine both the reported gift and the annuity payments required under the arrangement. Valuation may also be necessary when property is later substituted, distributed, or transferred. Unsupported assumptions or inconsistent values can undermine the position that exchanged assets had equivalent value.
3. Grantor notes may invite additional scrutiny
The Elcan dispute does not conclusively establish that a grantor’s promissory note can never be used in a GRAT transaction. It does demonstrate that the practice can create substantial controversy. Until the Tax Court provides additional guidance, families and advisors should carefully evaluate whether cash or readily valued marketable property can be used to satisfy annuity obligations instead.
4. Annuity payments require careful execution
Required payments should be calculated accurately, completed by the applicable deadline, and supported by clear financial records. Documentation should identify the amount due, payment date, property used for payment, fair market value, trustee approval, and relevant account activity.
5. Asset substitutions should be commercially supportable
A substitution power generally requires an exchange for property of equivalent value. That standard becomes especially important when the transaction involves related parties, closely held interests, or personal notes. Advisors should consider documenting the valuation methodology, note terms, applicable interest rate, repayment capacity, collateral, trustee review, and business purpose.
6. Advisors must coordinate
GRAT planning often involves an estate-planning attorney, CPA, valuation professional, trustee, investment adviser, and family office. Decisions made by one advisor can affect the work performed by everyone else. A coordinated administration calendar and periodic review process can help identify issues before an annuity deadline or asset exchange occurs.
Does this mean families should avoid GRATs?
Not necessarily. GRATs remain an established estate-planning strategy. The more appropriate conclusion is that families should avoid treating them as “set it and forget it” arrangements.
The Elcan case involves unusually large transactions and a specific method of using personal promissory notes. Most GRATs will not involve similar amounts or facts. Even so, the principles highlighted by the dispute apply broadly.
- Use qualified legal and tax professionals.
- Obtain credible valuations.
- Follow the trust agreement.
- Make payments correctly and on time.
- Document related-party transactions.
- Review the trust’s administration periodically.
The bottom line
Elcan v. Commissioner has not invalidated GRATs. It has, however, placed renewed attention on the difference between creating a tax-planning structure and administering it successfully.
For business owners and affluent families, the central lesson is straightforward: tax outcomes depend on execution. Strong valuation support, complete records, and coordination among advisors can be just as important as the original planning documents.
