Do you trust the federal tax system to accommodate taxpayer errors in reporting?
The IRS recently granted a taxpayer a 120-day extension to correctly allocate generation-skipping transfer (GST) exemption for an irrevocable trust. This rare relief follows a filing error where an accountant mistakenly elected to opt out of automatic exemption allocation on Form 709.
Why it matters
Mistakenly opting out of automatic GST exemption allocation can result in unintended tax consequences for trust assets. Seeking a formal private letter ruling allows taxpayers to rectify professional errors that would otherwise permanently expose transfers to generation-skipping taxes.
The IRS granted a 120-day extension to fix the GST exemption allocation error. This regulatory relief enables taxpayers to correct filings after the original Form 709 deadline has passed.
The players
Internal Revenue Service
The federal agency responsible for tax administration, regulatory enforcement, and issuing private letter rulings.
The details
The taxpayer created an irrevocable trust for descendants but accidentally triggered an opt-out of automatic GST exemption allocation under I.R.C. section 2632(c)(5). By petitioning for a private letter ruling under I.R.C. section 2642, the taxpayer demonstrated that they acted reasonably and in good faith. The IRS determined that the criteria under Treas. Reg. section 26.2642-7 were met, permitting the taxpayer to retroactively allocate the exemption despite the initial professional error.

Money Landscape
This case highlights the complexities surrounding the generation-skipping transfer tax and the specific requirements under I.R.C. section 2642. It serves as a reminder that administrative relief is available when tax professional errors interfere with estate planning objectives.
If you discover an error on your Form 709 regarding GST exemption elections, consult with a qualified tax professional immediately to discuss the feasibility of a private letter ruling request. This process can be costly and time-consuming, so ensuring your accountant reviews automatic election settings remains the primary defense against such issues.
The takeaway
Tax mistakes on estate filings are not always permanent if you can demonstrate a good faith error. Always review your filed Form 709 to verify that any elections regarding automatic GST exemption allocations align with your long-term estate planning strategy.
