IRS Grants Extension for QTIP and Reverse QTIP Elections Due to CPA Error

The $12M Mistake: How a CPA’s Error Nearly Cost an Estate Millions

A CPA’s failure to properly elect Qualified Terminable Interest Property (QTIP) and reverse QTIP treatment on Form 706 nearly cost an estate $12 million in avoidable estate and GST taxes. The IRS granted a 120-day extension under § 301.9100-3, which allows late elections if the taxpayer acted in good faith and the government suffered no prejudice. The ruling underscores a critical lesson: Taxpayers must verify that professionals correctly file elections—because once a return is filed, errors can trigger massive tax liabilities.

The Trust That Almost Wasn’t: A Chronology of the CPA’s Error

The Family Trust began as a revocable agreement executed by the Decedent and Spouse on Date 1, later amended and restated on Date 2. Its structure was designed to maximize tax efficiency: Section 5.01 allocated the surviving spouse’s separate and community property to a survivor’s trust, while Section 5.02 triggered irrevocability upon the first settlor’s death. Section 7.01 carved out a marital share for QTIP treatment, with Section 7.02 further dividing it into a GST-exempt QTIP trust and a non-exempt QTIP trust. The GST-exempt trust’s numerator was the Decedent’s GST exemption divided by the marital share’s value, ensuring the exemption shielded future generations.

The Decedent died on Date 3, leaving Spouse as executor. The trust’s terms required Spouse to file Form 706 and make QTIP and reverse QTIP elections to preserve the marital deduction and allocate the GST exemption. However, the CPA assigned to prepare the return misclassified the marital share property as “all other property” on Schedule M and omitted any QTIP designation. No Schedule R was filed, leaving the reverse QTIP election unmade. The error stemmed from a failure to reconcile the trust’s technical allocations with the return’s reporting requirements, despite the trust’s explicit QTIP provisions. The CPA’s oversight meant the estate lost the critical tax deferral and exemption benefits the trust’s structure had intended to provide.

QTIP and Reverse QTIP Elections: The Cost of Oversight

The CPA’s failure to file the QTIP election on Form 706, Schedule M and the reverse QTIP election on Schedule R triggered two avoidable tax risks: the loss of the marital deduction and the forfeiture of the decedent’s GST exemption. These elections are not optional—they are the legal mechanism that unlocks the tax benefits the trust was designed to provide.

Without the QTIP election, the estate lost the marital deduction, exposing the QTIP property to immediate estate tax. Without the reverse QTIP election, the surviving spouse’s GST exemption would apply to future distributions, risking a 40% GST tax on transfers to grandchildren or other skip persons. The trust’s structure—dividing the marital share into GST-exempt and non-exempt QTIP trusts—meant the CPA’s error had compounded consequences, turning a tax-efficient plan into a liability.

The IRS’s Lifeline: A Narrow Escape

The estate avoided a $12 million tax bill thanks to IRS Revenue Procedure 301.9100-3, which allows late tax elections if the taxpayer acted in good faith and the IRS suffered no prejudice. The CPA’s error—misclassifying the marital share on Schedule M and omitting Schedule R—was deemed a reasonable mistake under § 301.9100-3(b)(1)(v), as the CPA’s oversight stemmed from a technical misalignment between the trust’s terms and the tax return’s reporting requirements.

The IRS granted a 120-day extension to file a corrected Form 706, but with strict conditions: no distributions to non-spouse beneficiaries and no taxable events during the extension period. This ensured the IRS faced no disadvantage from the delay. While the relief was a lifeline, it was not a guarantee—future cases may not receive the same outcome.

Lessons for Taxpayers: Avoiding the $12 Million Mistake

This case highlights three critical takeaways for taxpayers and practitioners:

1. QTIP and reverse QTIP elections are non-negotiable. Missing either election—even due to professional oversight—can trigger immediate estate tax or GST tax exposure. Always verify that Schedule M and Schedule R are correctly filed with Form 706.

2. Good faith is not enough. While the IRS granted relief here, § 301.9100-3 is not a blanket solution. Future cases may not receive the same outcome, especially if the error stems from negligence rather than a technical misalignment.

3. Act fast if an error occurs. If an election is missed, file for relief under § 301.9100-3 immediately, document the mistake, and ensure no distributions or taxable events occur during the extension period. Delaying action risks permanent tax consequences.
