Can a generation skipping trust bypass taxes for grandchildren

As an estate planning attorney and CPA with over 35 years of experience here in Escondido, I’ve seen far too many carefully crafted estate plans derailed by seemingly minor oversights. Just last month, Randall spent years building a trust to provide for his grandchildren’s education, only to discover a crucial codicil was never properly executed. The resulting probate fight cost his heirs over $80,000 in legal fees and delayed distributions for nearly two years. It’s a painful reminder that precision is paramount.

What exactly is a Generation-Skipping Trust?

A Generation-Skipping Trust (GST Trust) is designed to transfer assets to grandchildren (or even more remote descendants) while avoiding estate taxes at each generation. Without a GST Trust, assets would be subject to estate tax when passing from you to your children, and again when passing from your children to your grandchildren. This “double taxation” is precisely what a GST Trust aims to eliminate. However, it’s not a simple, automatic bypass. There are very specific rules and requirements that must be met, and significant tax consequences if they aren’t.

How does the GST Tax Exemption work?

The key to a successful GST Trust is utilizing the federal generation-skipping transfer (GST) tax exemption. 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. It’s crucial to understand this isn’t a limitless exemption. It’s combined with your lifetime gift and estate tax exemption, requiring careful planning to maximize its benefit. As a CPA, I emphasize the importance of allocating this exemption during your lifetime. Procrastination can lead to missed opportunities, especially with the ongoing uncertainty surrounding federal estate tax laws.

What happens if I don’t properly fund the trust with real estate?

Many clients assume simply naming the GST Trust as a beneficiary is sufficient. That’s a dangerous misconception. We recently encountered a situation where a client intended a vacation home to be held within the GST Trust, but it remained solely in his name. Upon his passing, the property triggered a full reassessment under Prop 19, significantly increasing the property tax burden for his grandchildren. 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). Remember, this is a Petition – a court order – not a simple affidavit. A properly executed deed transferring the property before death is always the safest route.

What about digital assets and business interests?

The modern estate plan must address assets beyond traditional property and securities. 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. Similarly, 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 details may seem minor, but they can create substantial hurdles for your trustee.

How long can a GST Trust last in California?

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 a trust created today will ultimately terminate, and the assets will be distributed. Careful drafting is essential to ensure the trust aligns with your long-term family goals and minimizes potential tax consequences upon termination.

• Tax Efficiency: GST Trusts minimize estate taxes across multiple generations.
• Asset Protection: Properly structured trusts can shield assets from creditors.
• Control: You dictate how and when assets are distributed to future generations.
• Professional Guidance: A qualified attorney and CPA are critical to navigating complex rules.

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

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.

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

• 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.
