Lloyd called, panicked. His father had meticulously crafted a generation-skipping trust in 2015, intending to shield assets from estate tax and provide for his grandchildren. Now, after a falling out with his son, Lloyd’s father had attempted to amend the trust with a hastily written codicil. The codicil was deemed invalid due to improper witnessing, leaving a $3.2 million trust exposed to potential estate tax and, more importantly, a fractured family. Lloyd’s immediate concern wasn’t the tax implications, but the realization that his father’s intentions – securing a future for his grandchildren – were now in jeopardy due to a technical error.
What are the biggest risks with a poorly drafted generation-skipping trust?

The story with Lloyd is tragically common. Generation-skipping trusts (GSTs) are powerful tools, but they’re not foolproof. A GST is designed to transfer assets to grandchildren (or more remote descendants) without incurring estate tax at each generation. The potential tax savings are significant, but only if the trust is impeccably structured and maintained. The most common pitfalls include failing to allocate the GST tax exemption, improper funding, and, as Lloyd experienced, a flawed amendment process. A seemingly minor error can unravel years of careful planning, exposing the trust – and the beneficiaries – to substantial tax liability.
How does the OBBBA affect GST tax planning for 2026?
Planning for GSTs has recently become more predictable with the passage of the OBBBA (One Big Beautiful Bill Act). Effective Jan 1, 2026, the OBBBA permanently set the Federal Generation-Skipping Transfer (GST) Tax Exemption to $15 million per person; failing to allocate this exemption on Form 709 exposes the trust to a flat 40% tax on every distribution to grandchildren. Previously, the exemption amount fluctuated with the estate tax exemption, creating uncertainty. While the $15 million figure provides stability, it’s crucial to actively make the election to apply the exemption – it doesn’t happen automatically. We’ve seen clients lose significant tax benefits simply because they overlooked this step.
What happens if my trust exceeds the 90-year rule in California?
California’s rules regarding trust duration can be particularly restrictive. Unlike ‘dynasty friendly’ states like South Dakota, California is bound by the Uniform Statutory Rule Against Perpetuities (USRAP), which generally limits the trust’s lifespan to 90 years unless specific savings clauses are used. This means that if your trust doesn’t include provisions to extend its life beyond that timeframe, the assets will eventually be distributed, potentially defeating the purpose of the multi-generational planning. It’s not enough to simply intend for the trust to last; the language must be precise and compliant with USRAP.
What are the property tax implications of transferring a home to a GST trust in California?
California’s property tax landscape adds another layer of complexity to GST planning. Under Prop 19, transferring a home to grandchildren via a GST Trust almost always triggers a property tax reassessment to current market value, as the ‘grandparent-grandchild’ exclusion is severely restricted compared to the old Prop 58 rules. This can significantly increase the ongoing cost of ownership for the beneficiaries. Careful consideration must be given to whether the tax benefits of the GST outweigh the potential property tax burden.
What happens if a property intended for the GST Trust is still in my name when I pass away?
We frequently encounter situations where clients intend to transfer a property into a GST trust but haven’t completed the transfer before their death. For deaths on or after April 1, 2025, a home intended for the GST trust but left in the settlor’s name (valued up to $750,000) qualifies for a ‘Petition for Succession’ under AB 2016 (Probate Code § 13151). It’s critical to understand the difference: this is a “Petition” (requiring a Judge’s Order) not an “Affidavit.” The Petition allows for a streamlined transfer, avoiding full probate, but it’s subject to court approval and has specific requirements. Failing to utilize this procedure can result in the property being subject to full probate, significantly increasing costs and delays.
How does a CPA background help with GST trust planning?
As both an Estate Planning Attorney and a CPA with over 35 years of experience, I bring a unique perspective to GST planning. Many attorneys focus solely on the legal aspects, but a deep understanding of tax implications – particularly the step-up in basis, capital gains, and asset valuation – is essential. Properly structuring the trust can minimize capital gains taxes when assets are distributed to future generations. Furthermore, accurate valuation is crucial for both GST tax purposes and to avoid potential IRS scrutiny. I’m adept at navigating these complex financial considerations, ensuring that the trust is optimized for long-term tax efficiency.
What about digital assets held within the GST trust?
In today’s digital age, it’s vital to address the issue of digital assets. Without specific RUFADAA language (Probate Code § 870) in the GST Trust, service providers can legally block your trustee from accessing crypto wallets or cloud accounts intended for future generations. This is a significant risk, as digital assets can represent a substantial portion of the trust’s holdings. We routinely include robust RUFADAA provisions to ensure that the trustee has the necessary access and control.
Are there any FinCEN reporting requirements for LLCs held within the trust?
The rules surrounding Beneficial Ownership Information (BOI) reporting are constantly evolving. While domestic U.S. LLCs held in the trust are exempt from BOI reporting as of March 2025, trustees managing foreign-registered entities must still file updates with FinCEN within 30 days to avoid federal fines. It’s essential to stay abreast of these regulations and ensure compliance.
How do California trustee duties and funding rules shape the outcome for beneficiaries?
The advantage of a California trust is control and continuity, but this relies entirely on accurate funding and disciplined administration. Without clear asset titles and strict adherence to fiduciary standards, a private trust can quickly become a subject of public litigation over mismanagement, capacity, or undue influence.
- Disputes: Prepare for potential trust litigation if terms are vague.
- Execution: Follow strict trust administration to avoid liability.
- The Legacy: Create philanthropic trust options for tax efficiency.
California trust planning is most effective when the structure is matched to the specific family goal and assets are fully funded into the trust name. When administration is handled with transparency and adherence to the Probate Code, the trust can fulfill its promise of privacy and efficiency.

Federal GST Tax Exemption: IRS Estate & GST Tax Guidelines
Reflects the inflation-adjusted exemption effective January 1, 2026, which sets the GST Tax Exemption at approximately $15 million per person. Proper allocation of this exemption is the only way to shield trust assets from the flat 40% tax on distributions to grandchildren. -
Trust Duration Limits (USRAP): California Probate Code § 21205 (90-Year Rule)
California follows the Uniform Statutory Rule Against Perpetuities. This statute generally limits a Generation-Skipping Trust’s validity to 90 years, preventing “forever” trusts common in other jurisdictions. -
Property Tax Reassessment (Prop 19): California State Board of Equalization (Prop 19)
Critical for GST planning. Prop 19 severely limits the “grandparent-grandchild” exclusion, meaning most real estate transfers to grandchildren will trigger a property tax increase to current market value unless the parents are deceased. -
Primary Residence Succession (AB 2016): California Probate Code § 13151 (Petition for Succession)
If a home intended for the GST trust was accidentally left out, this statute (effective April 1, 2025) allows a “Petition for Succession” for residences valued up to $750,000, avoiding a full probate. -
Digital Legacy (RUFADAA): California Probate Code § 870 (RUFADAA)
The authoritative statute for digital assets. Without specific RUFADAA provisions in the trust, multi-generational access to cryptocurrency and digital files can be legally denied by custodians. -
Business Compliance (FinCEN): FinCEN – Beneficial Ownership Information (BOI)
The Corporate Transparency Act applies to most GST trusts holding LLCs. Trustees must file a Beneficial Ownership Information (BOI) report for both domestic and foreign entities. Failure to report changes within 30 days can result in federal civil penalties of $500/day.
