What is a generation skipping trust

Lloyd just received devastating news: the codicil he signed last year, intended to add his granddaughter to his generation-skipping trust, was never properly witnessed. The trust, worth over $8 million, now faces potentially crippling estate taxes, wiping out a significant portion of what he hoped to leave for future generations. A simple error in execution could cost his family dearly.

Generation-skipping trusts (GST trusts) are powerful estate planning tools designed to transfer assets to grandchildren (or even more remote descendants) while avoiding both estate tax at your death and estate tax at your children’s deaths. The core idea is to “skip” a generation for tax purposes, allowing wealth to accumulate for the benefit of descendants several generations removed. This is a significant advantage, but it’s also a complex area of law requiring meticulous planning and execution.

How Does a GST Trust Differ From a Traditional Trust?

A typical revocable living trust distributes assets to your children upon your death. Those children then include those assets in their estate, subjecting them to estate tax upon their death. A GST trust, however, is specifically designed to hold assets and distribute them to grandchildren (or later generations) without triggering estate tax at the intermediate generation. This “skip” is the key to the tax benefits, but it also means strict compliance with IRS regulations is crucial. The trust document must explicitly state its intent to be a GST trust and properly allocate your GST exemption.

What are the Key Benefits of a GST Trust?

The primary benefit is, of course, tax savings. By skipping a generation, you effectively double the amount of wealth that can pass to future generations tax-free. However, GST trusts offer benefits beyond just tax reduction. They provide a mechanism for long-term wealth preservation, protecting assets from creditors and potentially irresponsible spending by intermediate generations. You can also maintain control over how and when assets are distributed to your grandchildren, ensuring they are used for purposes you approve of, such as education or charitable giving.

What are the Potential Downsides and Considerations?

GST trusts are not without their complexities. Once established, they are generally irrevocable, meaning you can’t easily change the terms. This requires careful consideration of your future circumstances and the needs of your beneficiaries. Another significant issue is the 90-year rule. 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 the trust will eventually terminate, and the assets will be distributed, even if you’d prefer they remain in trust for a longer period.

Furthermore, transferring a home to grandchildren via a GST Trust almost always triggers a property tax reassessment to current market value under Prop 19, as the ‘grandparent-grandchild’ exclusion is severely restricted compared to the old Prop 58 rules. This can create a substantial tax burden, negating some of the estate tax savings.

How Does the GST Tax Exemption Work?

Each individual has a GST tax exemption, which allows you to transfer a certain amount of assets to grandchildren without incurring the 40% generation-skipping transfer tax. Currently, that exemption is substantial—effective Jan 1, 2026, the OBBBA (One Big Beautiful Bill Act) 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. It’s crucial to properly allocate your exemption during your lifetime to maximize the benefits of the trust.

What About Assets Beyond Traditional Property?

Today’s estate planning must account for increasingly complex 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. Also, 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. Properly drafted trust language is essential to address these modern challenges.

What Happens If Assets Are Accidentally Left Out of the Trust?

This is where we see situations like Lloyd’s. If you intend an asset, like a house, to be included in the GST trust but fail to formally transfer it into the trust before your death, it remains part of your estate and will be subject to estate tax. 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 is vital to understand this is a “Petition” (Judge’s Order), NOT an “Affidavit.” This offers a streamlined process, but is limited in scope and availability.

As an estate planning attorney and CPA with over 35 years of experience, I’ve seen firsthand how a properly structured GST trust can protect and grow family wealth for generations. My accounting background gives me a unique advantage in understanding the tax implications of these trusts, particularly the crucial step-up in basis for assets transferred into the trust and the potential capital gains ramifications of distributions. The complexities are significant, but the potential rewards – both financial and emotional – are well worth the effort with expert guidance.

What causes California trust administration to fail due to poor funding, vague terms, or trustee misconduct?

California trusts are designed to bypass probate and maintain privacy, yet they often fail when assets are not properly funded, trustee duties are ignored, or ambiguous terms trigger disputes. Even with a signed trust document, families can face court battles if the “operations manual” of the trust isn’t followed strictly under the Probate Code.

• Validation: Verify assets via funding and assets.
• Disputes: Handle trust litigation immediately.
• Flexibility: Know when to use irrevocable trusts rules.

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.

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

• 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.
