How Do Generation-Skipping Trusts Reduce Estate Taxes for Wealthy Families?
Last reviewed: July 2026
Generation-skipping trusts reduce estate taxes by transferring wealth to grandchildren and later generations while paying estate tax only once, not at every generational level. You allocate your generation-skipping transfer (GST) tax exemption to the trust, and the sheltered assets grow and pass down for decades without being taxed again at each death. For wealthy families, that single move can preserve millions that would otherwise be lost to repeated 40% estate tax bites.
Key Takeaways
- Generation-skipping trusts let wealth pass to grandchildren while skipping the estate tax that would normally apply at the children's generation.
- The GST tax is a flat 40%, charged on top of any gift or estate tax, making proper exemption allocation essential.
- Each person has a $15 million GST exemption in 2026, set permanently under the One Big Beautiful Bill Act.
- Married couples can shelter up to $30 million combined by coordinating their separate exemptions.

What Is a Generation-Skipping Trust?
A generation-skipping trust is an irrevocable trust that holds assets for the benefit of multiple generations while using your GST exemption to shelter those assets from generation-skipping transfer tax. You give up control of the assets, but in exchange they can grow and pass to your grandchildren and beyond without additional estate or GST tax at each generational level.
Here's the mechanics. Income and principal can be distributed to your children during their lifetimes based on need and the trust terms. When your children die, the assets are not pulled into their estates. Instead, they stay in trust for your grandchildren. That single design choice eliminates the estate tax that would otherwise apply when wealth moves from the children's generation to the grandchildren's.
Without a GST trust, wealth gets taxed twice on the way down. It's taxed at your death when it passes to your children, and again at their deaths when whatever remains passes to grandchildren. A properly structured generation-skipping trust removes the tax at the children's level entirely. That's the whole point.

How Does the Generation-Skipping Transfer Tax Work?
Congress created the generation-skipping transfer tax to stop wealthy families from dodging a layer of estate tax by handing assets straight to grandchildren. Without it, money could leap from grandparent to grandchild to great-grandchild and avoid estate tax at the skipped generation.
The GST tax applies at a flat 40% rate to transfers that skip a generation, whether made directly to grandchildren or to trusts that benefit multiple generations. According to the IRS, this tax stacks on top of any gift or estate tax that already applies, which is what makes it so punishing when families fail to plan.
The good news: each individual has a GST exemption equal to their estate tax exemption, which the One Big Beautiful Bill Act permanently set at $15 million per person in 2026. Allocate that exemption correctly and substantial wealth can pass to multiple generations free of GST tax. Married couples each get their own exemption, so a couple can shelter up to $30 million combined when they coordinate.
Generation-skipping transfers come in three flavors. A direct skip is a transfer straight to a grandchild or to a trust exclusively for grandchildren. A taxable termination happens when an interest ends, such as a child's interest ending at death and the assets staying in trust for grandchildren. A taxable distribution happens when a trust pays out to a skip person like a grandchild. Each can trigger GST tax if exemption was not allocated, which is why allocation timing matters as much as the trust structure itself. Jeff Judge notes: "Families often set up a beautifully structured generation-skipping trust and then fail to allocate the GST exemption to it properly at funding, which is the kind of timing mistake that can cost millions and can't always be undone."
What Is a Dynasty Trust?
A dynasty trust is the most aggressive form of generation-skipping planning, designed to last for multiple generations and, in states that have repealed the rule against perpetuities, potentially forever. These trusts preserve and grow wealth for children, grandchildren, great-grandchildren, and beyond without an estate tax hit at each transfer.
To build one, you transfer assets up to your GST exemption into an irrevocable trust and allocate your exemption to it. The trust makes discretionary distributions to descendants based on need, and trustees keep flexibility as family circumstances shift over time. Families often establish these trusts in states with favorable trust laws — Delaware, South Dakota, Nevada, and Alaska are the popular choices because they allow perpetual trusts, impose no state income tax on trust income, and offer strong asset protection.
The math over time is striking. Assets that would shrink 40% at each generational transfer instead compound untouched. Jeff Judge often tells clients that the real power isn't avoiding one tax bill — it's avoiding the same tax bill at every death for a century.

How Should You Allocate Your GST Exemption?
Using your GST exemption well takes intentional allocation, not autopilot. You can apply exemption to lifetime gifts to grandchildren or to trusts that benefit multiple generations. Automatic allocation rules exist, but leaning on them is how families end up with unsheltered transfers and surprise tax bills.
The smartest move is usually allocating exemption to high-growth assets early. The exemption is measured by value at the time of the gift, but it shelters all future appreciation. Gift $5 million in stock that grows to $20 million, and the entire $20 million stays outside the GST system — not just the original $5 million. That leverage is the single most valuable feature of GST planning, and it rewards families who act before the appreciation happens.

What Did OBBBA Change for Generation-Skipping Planning?
The One Big Beautiful Bill Act, signed July 4, 2025, permanently set the estate and GST tax exemption at $15 million per individual in 2026. That eliminated the sunset risk families faced under the 2017 Tax Cuts and Jobs Act, which had been scheduled to cut the exemption roughly in half. Families who planned around the old threshold remain fully sheltered.
Transfers already made under the high exemptions are locked in regardless of future law changes. The permanent $15 million threshold means generation-skipping planning stays highly advantageous for high-net-worth families, without the artificial deadline a scheduled reduction would have created. That removes urgency, but it doesn't remove the reason to plan — the earlier you fund a trust with appreciating assets, the more growth escapes estate tax.
Asset protection is a real bonus here. Trust assets are generally shielded from beneficiaries' creditors as long as distributions stay discretionary, protecting wealth across generations from divorces, lawsuits, and creditor claims. For grandchildren not yet born, you're building in financial security with guardrails already attached.

Frequently Asked Questions
What is the GST tax rate in 2026?
The generation-skipping transfer tax is a flat 40% rate in 2026, charged on transfers that skip a generation. It applies on top of any gift or estate tax that already applies, which makes proper allocation of your GST exemption essential to avoid stacking a second layer of tax on the same wealth.
How much can I transfer using my GST exemption?
Each individual can shelter up to $15 million in 2026 using their generation-skipping transfer tax exemption, set permanently under the One Big Beautiful Bill Act. Married couples each have a separate exemption, so a couple can transfer up to $30 million combined into generation-skipping structures when they coordinate their allocations carefully.
What is the difference between a generation-skipping trust and a dynasty trust?
A generation-skipping trust holds assets for multiple generations while using your GST exemption to avoid tax at each generational transfer. A dynasty trust is a specific, more aggressive version designed to last for many generations or indefinitely in states that allow perpetual trusts, such as Delaware, South Dakota, Nevada, and Alaska.
Are assets in a generation-skipping trust protected from creditors?
Yes, assets in a generation-skipping trust are generally protected from beneficiaries' creditors as long as distributions are discretionary rather than mandatory. This protection extends across generations, shielding family wealth from divorces, lawsuits, and creditor claims, which is one reason these trusts appeal to families thinking decades into the future.
Do I lose control of assets placed in a generation-skipping trust?
Yes, a generation-skipping trust is irrevocable, so you give up direct control of the assets you contribute. In exchange, the assets escape estate and GST tax at each generation. Trust protectors, discretionary distribution standards, and decanting provisions in some states can preserve meaningful flexibility without pulling the assets back into anyone's estate.
