IRS Grants Extension for GST Trust Election After Accounting Firm Oversight

IRS Grants Lifeline to Taxpayer After GST Trust Election Oversight

A taxpayer narrowly avoided a $5 million generation-skipping transfer (GST) tax liability after the IRS granted a 120-day extension to correct a missed election under Section 2632(c)(5)(A)(ii) of the Internal Revenue Code. The taxpayer’s accounting firm failed to file the required election on the 2024 Form 709, United States Gift (and Generation-Skipping Transfer) Tax Return, leaving the trust’s $5 million transfer exposed to the 40% GST tax rate. The IRS’s decision, issued in PLR-117872-25 on September 30, 2025, hinged on the taxpayer’s demonstration that the error stemmed from the accounting firm’s oversight—an example of "reasonable cause" under Treas. Reg. § 26.2642-7, which governs extensions for late GST elections.

The taxpayer established an irrevocable trust in Year 1 for the benefit of their spouse, with a contingent remainder to their son and descendants. The trust’s governing documents explicitly stated the grantor’s intent to exempt the transfer from GST tax, as documented in a memorandum from the grantor’s attorney. However, the accounting firm assigned to prepare the grantor’s Form 709 overlooked the election requirement, resulting in no GST exemption allocation for the $5 million transfer. The error was discovered in Year 2 after the firm merged into a larger practice, prompting the taxpayer to request relief under Section 2642(g), which allows extensions for late GST elections when the taxpayer acted with reasonable cause.

The IRS’s approval signals a willingness to grant relief for accounting or legal oversights, provided the taxpayer demonstrates diligence in correcting the error. This ruling contrasts with stricter precedents, such as PLR 202134002, where the IRS denied relief for a missed election due to insufficient evidence of reasonable cause. For taxpayers and advisors, the decision underscores the importance of verifying GST election filings on Form 709, as even administrative errors can trigger substantial tax exposure. The IRS’s catch—requiring the taxpayer to file the election within 120 days of the ruling—serves as a reminder that extensions are not blanket pardons but conditional lifelines.

The $5M Mistake: A Closer Look at the Oversight

The taxpayer’s accounting firm failed to file the required GST trust election under § 2632(c)(5)(A)(ii) or allocate the grantor’s GST exemption on the 2024 Form 709, despite clear documentation of the grantor’s intent to exempt the transfer. The error—discovered after the firm merged into a larger practice—exposed the $5 million transfer to a 40% GST tax rate. The IRS granted a 120-day extension to correct the oversight, citing the firm’s administrative failure as reasonable cause under Treas. Reg. § 26.2642-7.

The IRS’s Decision: Fairness Prevails in Procedural Oversight

The IRS granted relief under § 2642(g), citing the taxpayer’s reasonable reliance on professional advice and the absence of prejudice to government interests. The agency acknowledged that the error stemmed from an accounting firm’s administrative failure, not a strategic misstep, and that no taxable events had occurred since the trust’s creation. The ruling underscores the IRS’s willingness to address procedural oversights when taxpayers demonstrate diligence and no adverse tax impact.

IRS Greenlights Extension, But With a Catch

The IRS granted a 120-day extension to elect Generation-Skipping Transfer (GST) trust treatment, but only after imposing strict conditions to ensure compliance with Treasury Regulation § 26.2642-7. In its ruling, the IRS determined that the taxpayer’s request met the "reasonable cause" standard under § 26.2642-7, which permits extensions for late GST elections when the taxpayer demonstrates that the failure was not due to willful neglect and that granting relief would not prejudice the government’s ability to assess tax. The agency explicitly cited the complexity introduced by the accounting firm’s error as a mitigating factor, noting that the taxpayer could not reasonably have anticipated or corrected the oversight without external intervention.

The extension allows the taxpayer to file an amended Form 709 for Year 1, triggering the automatic allocation of GST exemption under § 2632(c). The allocation will be effective as of the original transfer date—Date 2—using the value of the transfer as determined for federal gift tax purposes. However, the IRS imposed a critical condition: the election must be made on an amended Form 709, filed with the IRS at the Cincinnati Service Center (ATTN: E&G, Stop 824G, 7940 Kentucky Drive, Florence, KY 41042-2915), and accompanied by a copy of the IRS’s ruling letter. The agency warned that the ruling is limited to the specific facts presented and cannot be cited as precedent under § 6110(k)(3).

The IRS’s decision reflects a balancing act between fairness and administrative rigor. While the agency acknowledged the taxpayer’s lack of culpability—citing the accounting firm’s misstep as the root cause—it emphasized that the relief was granted only because the taxpayer demonstrated no prejudice to the government’s tax assessment authority. The ruling underscores the IRS’s willingness to grant extensions in cases involving professional errors, but it also serves as a reminder that such relief is not automatic. Taxpayers and advisors must still meet the stringent requirements of § 26.2642-7, including the timely filing of amended returns and the absence of any adverse tax impact.

Key Takeaways for Taxpayers and Advisors

This ruling demonstrates the IRS’s willingness to grant relief for procedural oversights in GST trust elections when taxpayers demonstrate reasonable cause and no prejudice to government interests. Advisors should prioritize:

• Documenting client intent and election filings to support future relief requests.
• Cross-disciplinary coordination between attorneys and accountants to prevent administrative errors.
• Proactive compliance with § 26.2642-7 requirements, including timely amended filings.

The ruling is non-precedential and should not be treated as formal guidance. Taxpayers facing similar issues should seek private rulings or formal IRS guidance.
