IRS Grants Extension for QTIP Election After Accounting Firm Oversight

IRS Grants 120-Day Extension for QTIP Election After Accounting Firm Fails to File

An estate recently secured a 120-day extension to make a QTIP election under § 2056(b)(7) after an accounting firm’s error nearly cost it a critical marital deduction. The taxpayer requested relief under § 301.9100-3, which allows extensions for regulatory elections when taxpayers act reasonably and in good faith. The IRS granted the extension, sparing the estate from losing the deduction that would have triggered an immediate estate tax liability. The case underscores the high stakes of QTIP elections—where a missed filing by a professional can mean the difference between deferring tax and owing millions.

The $X Million Mistake: How an Accounting Firm’s Oversight Nearly Cost an Estate Its Marital Deduction

The estate’s troubles began with meticulous planning that unraveled due to a single filing error. On Date 1, the decedent and spouse established a revocable trust, naming themselves as co-trustees. The trust included a standard pour-over provision: upon the decedent’s death, the trust would split into three irrevocable trusts—the Survivor’s Trust (funded with the spouse’s separate and community property), the Bypass Trust (funded with the largest tax-free amount), and the Marital Trust (funded with the remainder). The Marital Trust was designed to provide the spouse with all net income quarterly, with principal distributions available for reasonable support. Crucially, the trust document explicitly stated its purpose was to qualify for the marital deduction under § 2056, with authority for the trustee to elect qualified terminable interest property (QTIP) treatment under § 2056(b)(7).

The decedent died on Date 2, triggering the trust’s division. The estate engaged Accounting Firm to prepare Form 706, the federal estate tax return, and to make all required elections, including the QTIP election for the Marital Trust. The firm filed the return on Date 3, reporting the estate’s assets and claiming the marital deduction—but omitting the Marital Trust assets entirely from the QTIP election on Schedule M. The election statement was left blank, despite the trust’s terms and the estate’s intent to qualify for the deduction.

Months later, on Date 4, the estate’s attorney reviewed the filed return and discovered the omission. The Marital Trust’s assets had been reported on Form 706, but no QTIP election had been made. Without the election, the marital deduction was automatically forfeited, exposing the estate to an immediate estate tax liability on the Marital Trust’s value—potentially millions in unpaid tax, plus penalties and interest. The oversight was not a drafting error in the trust itself, but a procedural failure in the estate tax filing process. The accounting firm’s mistake nearly erased the tax planning that had preserved the estate’s wealth for the next generation.

QTIP Elections: What Went Wrong and Why It Matters

The accounting firm’s failure to file the QTIP election nearly cost the estate its marital deduction—a mistake that would have triggered an immediate estate tax liability on the Marital Trust’s assets. To understand why this error was so critical, it’s essential to grasp the legal framework governing QTIP elections and the marital deduction.

The marital deduction under § 2056(a) allows estates to deduct the value of property passing to a surviving spouse, deferring estate tax until the spouse’s death. But this deduction comes with strict limitations. § 2056(b)(1) blocks the deduction for "terminable interests"—property where the spouse’s interest could end due to a future event, such as remarriage or the death of a beneficiary. This rule prevents tax avoidance by ensuring the marital deduction only applies to property the spouse truly controls for life.

That’s where the QTIP election under § 2056(b)(7) comes in. It overrides the terminable interest rule by allowing estates to treat qualifying property as passing to the surviving spouse—if the executor makes a formal election. To qualify, the surviving spouse must receive all the income from the property (paid at least annually) and no one else can have a power to appoint the property during their lifetime. The election is made on Schedule M of Form 706, the estate tax return, and once filed, it is irrevocable.

The accounting firm’s error was procedural, not substantive: they drafted the trust correctly but failed to file the QTIP election on Schedule M. Without it, the Marital Trust’s assets lost their marital deduction status, exposing the estate to an immediate tax bill—potentially millions in unpaid tax, penalties, and interest. The IRS’s later grant of a 120-day extension under § 301.9100-3 saved the day, but only because the estate acted quickly to correct the mistake. For other estates, such an oversight could mean the difference between preserving wealth for heirs and triggering a costly tax liability.

IRS Relief Under § 301.9100-3: When Good Faith and Professional Reliance Save the Day

The IRS granted relief under § 301.9100-3, which permits extensions for regulatory elections when taxpayers fail to meet deadlines due to reasonable cause. To qualify, the taxpayer must demonstrate three core requirements: the action was taken reasonably and in good faith, the delay did not prejudice the government’s interests, and the request was made promptly after discovering the error.

The estate’s case hinged on § 301.9100-3(b)(1)(v), which deems reliance on a qualified tax professional as reasonable and in good faith if the professional failed to make or advise the election. The IRS concluded the estate met this standard because the missed QTIP election resulted solely from the accounting firm’s oversight, not any negligence by the estate. The agency emphasized that the firm’s error—rather than any misstep by the taxpayer—was the sole cause of the missed deadline, satisfying the "good faith" and "no prejudice" prongs.

Based on these facts, the IRS granted a 120-day extension from the date of the ruling letter, allowing the estate to file the QTIP election on a supplemental Form 706. The decision underscores the IRS’s willingness to provide relief when taxpayers act diligently and rely on professional advice, even when that advice proves flawed. For estates facing similar oversights, this ruling highlights the importance of prompt corrective action and documented reliance on advisors to secure discretionary relief under § 301.9100-3.

Lessons for Estates and Practitioners: Avoiding QTIP Election Pitfalls

The IRS’s decision to grant a 120-day extension in this case highlights critical lessons for estates and practitioners handling QTIP elections. First, double-checking QTIP elections on Form 706 is non-negotiable, particularly for complex trusts where terminable interests or multiple beneficiaries create ambiguity. A missed election—even due to an advisor’s oversight—can result in the loss of the marital deduction, triggering immediate estate tax liability. In this case, the accounting firm’s failure to file Schedule M nearly cost the estate its deduction, underscoring the need for rigorous review processes.

Second, § 301.9100-3 relief is a lifeline but not a guarantee. This regulation allows estates to request extensions for late regulatory elections if the failure was due to reasonable cause, such as reliance on a professional. However, the IRS’s leniency hinges on prompt corrective action—estates must file a Private Letter Ruling request within a reasonable time, typically within 12 months of the original deadline. Delaying relief requests, as seen in PLR 202215002, can result in denial. Practitioners should document advisor communications and filing attempts to strengthen their case for relief.

Third, Private Letter Rulings are non-precedential, meaning other estates cannot assume identical relief. Each PLR is tailored to specific facts, and the IRS’s willingness to grant extensions depends on the circumstances. For example, the IRS granted relief in PLR 202330005 due to the estate’s diligence and reliance on a flawed advisor, but denied it in Estate of Mary D. Smith (T.C. Memo. 2021-127) because the trust terms failed to meet § 2056(b)(7) requirements. Estates should not rely on past PLRs as a blueprint for future relief.

To avoid similar mistakes, estates and practitioners should adopt best practices, including reviewing QTIP elections with multiple professionals, using checklists for Form 706, and verifying trust terms align with § 2056(b)(7). The potential tax consequences of a missed QTIP election—loss of the marital deduction and higher estate tax liability—are severe, making these precautions essential. For estates facing similar oversights, this ruling serves as a reminder: act fast, document reliance, and seek expert guidance to secure discretionary relief under § 301.9100-3.
