The generation-skipping transfer tax, or GST tax, is a federal tax on gifts or inheritances that are passed directly to grandchildren, skipping their parents. It also applies if the recipient is more than 37½ years younger than the giver.
This tax is charged at the highest federal gift and estate tax rate (40% in 2024) and it’s in addition to any other federal gift or
estate taxes owed. This tax is to ensure that the same estate taxes apply as if the inheritance had first gone to the parents before reaching the grandchildren.
The person giving the gift is called the transferor, and the person receiving it is the skip person. While many people use a grandchild as a skip person, the recipient doesn't have to be a family member.
Before GST taxes were introduced in 1976, wealthy individuals could use generation skipping to transfer money and property to their grandchildren without paying federal estate taxes. The law was created to close this loophole and prevent skipping a generation to avoid double estate taxation.
The tax applies in a few different scenarios. First, there are direct skips, which occur when assets are transferred directly to a skip person, either immediately or through a trust. In these cases, the GSTT is paid by the giver or their estate at the time of the transfer, based on the value of the assets given.
Another situation involves taxable distributions. This happens when an irrevocable trust makes a payment to a skip person, but it’s not classified as a direct skip or a taxable termination. Taxable terminations also occur when an interest in a trust ends, such as when a beneficiary dies or the trust term expires, and there are no remaining beneficiaries who are not skip persons.
In this case, the trustee is responsible for paying the GSTT when the interest terminates. Each of these situations ensures that transfers and distributions to skip persons are taxed accordingly.
