What is a generation skipping trust

I recently had a client, Emily, come to me absolutely devastated. Her mother had meticulously drafted a trust to benefit Emily’s grandchildren, envisioning a legacy for generations. Unfortunately, a minor amendment – a codicil adjusting the trustee – was improperly executed, rendering it invalid in court. The result? A $350,000 legal battle, significant delays in funding the trust, and a lot of unnecessary stress for Emily and her family. This scenario, while frustratingly common, highlights the critical importance of precise trust drafting, especially when dealing with complex structures like Generation-Skipping Trusts (GST Trusts).

A GST Trust is designed to transfer assets to grandchildren (or more remote descendants) while potentially avoiding estate taxes at each generation. Traditionally, when you leave assets to your children, estate taxes are paid twice – once when your children inherit from you, and again when your grandchildren inherit from your children. A GST Trust effectively skips this second layer of tax by allowing assets to pass directly to the grandchildren, minimizing those tax liabilities. However, the rules governing these trusts are incredibly intricate, and a seemingly small error can have massive consequences.

As an Estate Planning Attorney and CPA with over 35 years of experience, I often emphasize to clients the distinct advantage of having a CPA involved in trust creation. We don’t just focus on who gets the assets; we analyze how the assets will be valued, the potential capital gains implications, and, crucially, how to maximize the step-up in basis. This is where a CPA’s expertise becomes invaluable – we can structure the trust to minimize tax burdens and ensure long-term financial stability for your beneficiaries.

What are the current tax implications of a GST Trust?

As of 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. Proper exemption planning is crucial, and the allocation process can be complex, requiring careful consideration of future gift tax strategies. It’s not enough to simply have $15 million; you must actively elect to apply the exemption to the trust.

What happens if the trust lasts too long?

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. A trust exceeding this timeframe can be deemed invalid, forcing a distribution of assets sooner than intended. We can incorporate specific clauses to extend the trust’s duration, but this requires a deep understanding of California trust law.

Will my grandchildren face property tax increases?

Unfortunately, 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. While there are limited exceptions, most beneficiaries will experience a significant increase in their property tax obligations. This often necessitates careful planning, potentially involving techniques like installment sales or strategic use of other exemptions.

What if my estate plan changes after the trust is established?

Life happens. And sometimes, we need to adjust our plans. If a home intended for the GST trust but left in the settlor’s name (valued up to $750,000) needs to be transferred after April 1, 2025, it qualifies for a ‘Petition for Succession’ under AB 2016 (Probate Code § 13151). It’s important to understand that this is a “Petition” (Judge’s Order), NOT an “Affidavit” – a Judge must approve the transfer. It’s a streamlined process compared to a full probate, but requires careful adherence to the probate code.

Are there any digital asset concerns?

Absolutely. 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 rapidly evolving area of law, and failing to address digital assets can render a significant portion of the trust inaccessible. I strongly recommend including a comprehensive digital asset plan within your trust documents.

What about business interests held within the trust?

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. These regulations are complex and constantly changing, so ongoing compliance is essential.

What determines whether a California trust settlement remains private or erupts into public litigation?

Success in trust administration depends on more than just the document; it requires active management of assets, precise accounting to beneficiaries, and careful navigation of tax rules. Whether dealing with a blended family or complex real estate, understanding the mechanics of trust law is the only way to ensure the grantor’s wishes survive scrutiny.

Ultimately, the success of a trust depends on the details—proper funding, clear terms, and a trustee willing to follow the rules. By anticipating friction points and documenting every step of the administration, fiduciaries can protect the estate and themselves from liability.

Verified Authority on California Generation-Skipping Trust (GST) Administration

• GST Tax Exemption (OBBBA): IRS Estate & GST Tax Guidelines
  Reflects the OBBBA update effective January 1, 2026, which sets the GST Tax Exemption at $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.
• 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)
  As of March 2025, domestic U.S. LLCs are exempt from mandatory BOI reporting. However, trustees managing foreign-registered entities must still comply with strict reporting windows to avoid penalties of $500/day.
