The Generation-Skipping Transfer Tax (GSTT) is a federal tax designed to prevent wealthy individuals from avoiding estate and gift taxes by skipping a generation when transferring assets to grandchildren or others 37.5+ years younger. It ensures that taxes are applied to wealth at each generational level.
The U.S. estate and gift tax system includes a generation-skipping transfer tax (GSTT) to address circumstances in which wealth is transferred to younger generations (such as grandchildren) or unrelated persons more than 37.5 years younger than the decedent.
The purpose of the GSTT is to prevent families from avoiding estate taxes by transferring assets directly to younger generations (e.g. grandchildren), bypassing the intermediate generation (e.g., children).
The generation-skipping transfer tax is a federal tax on a gift or inheritance that prevents the donor from avoiding estate taxes by skipping children in favor of grandchildren. With the generation-skipping transfer tax, grandchildren receive the same amount as if the inheritance were coming from their parents.
A generation skipping trust is a powerful estate planning tool, especially for individuals with large estates. They are a great way to help your family avoid paying estate taxes twice, when the estate passes to your children, and then again to your grandchildren.
Who pays the generation skipping transfer tax? The GST tax is paid by the grantor if using the direct generation skip strategy, or the beneficiary if using the generation-skipping transfer strategy. Keep in mind that the tax only applies to assets above the lifetime exemption amount.
One of the biggest disadvantages of a Generation-Skipping Trust is the fact that they are considered Irrevocable Trusts. This means you do not have the power to amend or cancel them. The assets contained within the Trust will also no longer be under your control, and will instead be administered by a Trustee.
In order to avoid the generation-skipping transfer tax on the initial transfer, an individual must use (allocate) some or all of one's GSTT exemption. The GSTT exemption may be used for both outright transfers as well as transfers in trust.
Disadvantages: Implementation challenges, initial compliance costs, and potential inflation in some sectors. It may also burden small businesses with complex tax filings.
Generation-skipping trusts fall into the category of irrevocable trusts. Despite the name, an irrevocable trust may sometimes be dissolved. If all the beneficiaries agree, the purpose of the trust has been fulfilled or is no longer possible, or a court issues an order to terminate, the trust can legally dissolve.
You can gift a grandchild up to the annual gift tax exclusion amount (around $19,000 per person in 2025/2026) without any tax implications or reporting; gifts exceeding this amount must be reported on a gift tax return (Form 709) but only count against your substantial lifetime gift tax exemption (nearly $14 million in 2025), meaning you likely won't pay tax until you've given away massive sums over your lifetime. Married couples can combine their exclusions to give double.
Every individual has a basic Inheritance Tax (IHT) threshold of £325,000, known as the Nil Rate Band. Assets below this value generally pass to beneficiaries free of tax. If the estate is worth more than that, IHT at 40% usually applies on the excess, unless exemptions or reliefs reduce the amount due.
Children generally inherit significant amounts tax-free due to the high federal estate tax exemption, which is $13.99 million per individual for 2025, with a planned reversion to a lower amount ($5 million adjusted for inflation) in 2026, meaning very large estates are taxed, but most inheritances fall below this threshold, though some states have their own inheritance taxes. Heirs also benefit from the "step-up in basis," which lowers capital gains tax on inherited assets like stocks and real estate.
If you die within 7 years of making a transfer into a trust your estate will have to pay Inheritance Tax at the full amount of 40%. This is instead of the reduced amount of 20% which is payable when the payment is made during your lifetime.
Contributions to the trust are generally subject to gift tax requirements during your lifetime. However, if certain conditions are met, assets placed in this type of trust (and appreciation on those assets over time) will be sheltered from estate tax after your death.
If you choose to put your house in an irrevocable trust that names your children as the beneficiaries, the property will no longer be part of your estate when you die. By removing it, there will be no estate taxes charged in the transfer and the property will not be subject to Medicaid estate recovery.
Give more money away
Lifetime gifting is a straightforward way to begin reducing your IHT bill. By gifting money during lifetime, that would have been part of an inheritance anyway, you reduce the size of your estate so that there is smaller amount subject to IHT on your death.
