Families in Silicon Valley have built remarkable wealth, and protecting that wealth across multiple generations is a priority that demands careful legal planning. Two tools that come up frequently in estate planning conversations are the dynasty trust and the generation-skipping trust. Both can shield assets from unnecessary taxation and keep wealth within a family for decades, but they are not the same thing. Understanding how each one works under California and federal law can help you make a more informed decision for your family’s future.
What Is a Generation-Skipping Trust?
A generation-skipping trust transfers assets to beneficiaries at least two generations below the grantor, bypassing estate taxes at the middle generation.
A generation-skipping trust, often called a GST, is designed to pass wealth directly to grandchildren or later descendants while skipping over the grantor’s children for transfer tax purposes. The key benefit is avoiding an additional layer of federal estate tax that would otherwise apply each time assets move from one generation to the next.
Federal law governs the generation-skipping transfer tax under Internal Revenue Code Sections 2601 through 2663. Every individual has a lifetime GST tax exemption, which the IRS adjusts annually for inflation. Starting in 2026, that exemption is permanently set at $15 million per individual, indexed for inflation. Assets transferred within this exemption threshold are entirely exempt from the 40% federal GST.
While California does not impose an independent GST tax rate beyond the federal rate, it maintains a mirror-state GST tax regime that requires a California GST return—Form GST(D) or GST(T)—to be filed with the State Controller’s Office whenever a federal GST return is required. Assets in a properly structured GST trust grow and are distributed to grandchildren or lower generations without triggering that additional federal tax layer, assuming the transfers fall within the exemption.
A generation-skipping trust typically has a defined lifespan. It may terminate when the grantor’s last child passes away, or be structured to last for a specific number of years. This is an important distinction from a dynasty trust.
What Is a Dynasty Trust?
A dynasty trust is a long-term irrevocable trust designed to hold and protect family wealth for multiple generations, sometimes indefinitely.
A dynasty trust takes the concepts behind a GST trust and extends them dramatically. The goal is not just to skip one generation of estate taxes but to keep assets inside a trust structure for as long as the law allows, potentially spanning 100 years or more.
California law currently limits the duration of most trusts under the state’s rule against perpetuities. Under California Probate Code Section 21205, California follows a 90-year bright-line rule against perpetuities. This means a nonvested interest in a California dynasty trust must generally vest or terminate within 90 years of creation, or 21 years after the death of an individual alive when the trust was created. Some families choose to form dynasty trusts in states like South Dakota or Nevada, which have abolished or significantly extended their perpetuities rules, and then administer those trusts from outside California.
A dynasty trust is structured as an irrevocable trust, meaning the grantor gives up control of the assets once they are transferred in. The trust holds and manages assets for beneficiaries across multiple generations and can use the grantor’s GST tax exemption to shelter those assets from transfer taxes throughout its lifespan. When assets remain in the trust and never become the outright property of any individual beneficiary, they also avoid estate taxation in each beneficiary’s estate.
Key Differences Between the Two
The main differences lie in duration, structure, and the scope of generational wealth protection each trust is designed to provide.
While both trusts use GST tax exemptions, they serve different planning objectives. A generation-skipping trust typically focuses on a defined transfer to grandchildren or to one or two subsequent generations. A dynasty trust is built for longevity, with the explicit purpose of preserving wealth across as many generations as the law permits.
Here are the core distinctions:
- Duration: A GST trust often ends when a specific generation reaches a certain age or milestone. A dynasty trust is designed to last as long as legally possible.
- Tax strategy: Both use the federal GST exemption, but a dynasty trust aims to eliminate estate taxes at every generational level for the trust’s entire life.
- Asset protection: Dynasty trusts generally offer stronger creditor protection because assets remain inside the trust rather than being distributed outright.
- State law considerations: California’s 90-year perpetuities limit affects dynasty trust planning in ways that do not apply in trust-friendly states.
Which Trust Makes Sense for Your Family?
The right choice depends on your family’s size, the value of your estate, your goals for future generations, and how long you want the trust to last.
For families in Fremont and the broader Silicon Valley area with significant real estate holdings, business interests, or investment portfolios, both tools can serve a meaningful purpose. A generation-skipping trust works well when your primary goal is passing wealth to grandchildren with minimal tax erosion. A dynasty trust is worth considering when your goal is building a lasting legacy that serves your family for generations far beyond your own.
Federal estate and gift tax laws are also subject to change. Under current law, following the One Big Beautiful Bill Act, the elevated exemption amounts are permanent, starting at $15 million in 2026, eliminating the pre-2025 sunset risk. Families with taxable estates should act while the current exemptions remain available, since locking in those exemptions now can produce significant long-term savings.
