A generation-skipping trust lets you pass wealth to your grandchildren, or even further down the family line, while shrinking the estate tax bill that would otherwise be charged at every generation along the way. It is powerful, but it is advanced planning that rewards careful, professional guidance.
If you have heard the term and assumed it was only for the ultra-wealthy, you are mostly right, but not entirely. This guide explains what a generation-skipping trust is, how the federal generation-skipping transfer (GST) tax works, who genuinely benefits, and the real tradeoffs to weigh before you commit.
What is a generation-skipping trust?
A generation-skipping trust is an irrevocable trust built to hold assets for beneficiaries who are two or more generations below you, most often your grandchildren. The defining feature is that it can pass wealth down the family line while reducing the number of times that wealth is taxed by the federal estate tax.
Normally, money moves down a family one generation at a time. You leave assets to your child; when your child dies, those assets may be taxed again before reaching your grandchild. Each generation can be a fresh taxable event. A generation-skipping trust is designed to break that chain. Often your children can still benefit from the trust during their lives, for example by receiving income, while the principal passes to your grandchildren without being counted in your children's taxable estates.
Despite the name, the trust does not have to cut your children out. The "skip" refers to skipping a layer of taxation, not skipping your family members entirely.
How the generation-skipping transfer (GST) tax works
Congress noticed long ago that wealthy families used these trusts to dodge the estate tax for generations. So it created a separate tax: the generation-skipping transfer tax. It applies on top of, not instead of, the regular gift and estate tax.
The GST tax targets transfers to a skip person, defined as someone two or more generations below you. There are three taxable events:
- Direct skips — an outright gift or bequest straight to a grandchild.
- Taxable distributions — a distribution from a trust to a skip person.
- Taxable terminations — when an interest ends (say, your child dies) and the trust then benefits only skip persons.
The GST tax rate is a flat 40%, the same as the top federal estate tax rate. That is what makes proper planning so valuable: an unplanned skip can be taxed at 40% on top of any estate tax already paid.
The GST exemption
Here is the good news. Every person has a lifetime GST exemption that mirrors the federal estate and gift tax exemption. For 2026, that amount is $15 million per person, or $30 million for a married couple, under the law signed in 2025, and it is indexed for inflation going forward. (For more on the broader number, see our guide to the federal estate tax exemption.)
When you fund a generation-skipping trust, you or your attorney allocate part of your GST exemption to it. Assets covered by the exemption can grow and pass to grandchildren entirely free of GST tax. Only transfers above your remaining exemption get hit with the 40% tax. Allocating the exemption correctly, and on time, is technical work, and mistakes are expensive and hard to undo, which is one reason this is firmly attorney territory.
Who actually benefits from a generation-skipping trust?
These trusts are not for everyone. They make the most sense when one or more of the following is true:
- Your estate is large enough to face federal estate tax. If your total wealth is comfortably under the $15 million exemption, you likely will not owe GST tax at all, and a simpler structure may serve you better.
- Your children are financially secure. If your kids do not need the full inheritance, passing it (or its growth) to grandchildren can keep more wealth in the family over time.
- You want long-term asset protection. Because the trust is irrevocable, assets held in it are generally shielded from a beneficiary's creditors, lawsuits, and divorces.
- You want control across generations. A trust can dictate how and when money is used, for education, a first home, or a safety net, long after you are gone.
For families below the estate-tax threshold, the non-tax benefits, like creditor protection and control, can still justify a trust. But often a trust fund for children or a standard living trust accomplishes the goal with far less complexity.
Generation-skipping trust vs. other common trusts
It helps to see where this tool sits among the alternatives.
| Feature | Generation-Skipping Trust | Revocable Living Trust | Standard Irrevocable Trust |
|---|---|---|---|
| Primary goal | Pass wealth to grandchildren, minimize tax at each generation | Avoid probate, manage assets in life | Remove assets from your taxable estate |
| Can you change it? | No (irrevocable) | Yes, anytime | No (irrevocable) |
| Skips a generation of estate tax? | Yes, that is the point | No | Not specifically |
| Creditor protection for heirs | Strong | Limited | Strong |
| Best for | High-net-worth families | Most households | Estates near the exemption |

The tradeoffs to weigh
No planning tool is free of downsides. Before you build one, sit with these honestly:
- Irrevocability. Once funded, you generally cannot take the assets back or rewrite the terms. You are giving up control today for benefits tomorrow.
- Complexity and cost. Drafting, funding, and administering a generation-skipping trust requires an experienced attorney and often ongoing tax filings. Expect meaningful setup fees and annual costs.
- Trustee responsibility. Someone must manage the trust for decades, possibly across generations. Choosing the right trustee, and understanding trustee responsibilities, is critical.
- Family dynamics. Skipping or limiting a child's access to wealth can cause hurt feelings if not communicated with care.
- Changing law. Exemption amounts shift with legislation. A plan built around today's numbers should be reviewed periodically.
How to get started the right way
A generation-skipping trust is not a do-it-yourself project. If it sounds like a fit, here is a sensible path:
- Tally your estate. Add up everything, including life insurance and retirement accounts, to see whether you are near the federal estate tax threshold.
- Clarify your goals. Are you chasing tax savings, asset protection, multi-generational control, or all three? The answer shapes the design.
- Hire an estate planning attorney. Look for one who handles high-net-worth and GST planning specifically. You can review our guide on how to find an estate planning attorney.
- Coordinate your whole plan. A generation-skipping trust should fit alongside your will, beneficiary designations, and the rest of your end-of-life plan, not stand alone.
- Review it regularly. Revisit the plan every few years and after major law changes or family events.
