What it means
Wealth handed straight down a family tree is normally taxed at each generational step, once when the parent dies and again when the child dies. A generation-skipping trust breaks that pattern by placing assets in a legal structure that the middle generation benefits from but does not own.
Because the child never owns the capital, it is not counted in the child's estate when they die. The child generation is typically given rights that feel generous in practice but stop short of ownership.
They might receive all the trust income for life, plus access to capital for health, education and maintenance, while an independent trustee controls anything beyond that. Those limits are what keep the assets outside their taxable estate.
The tax benefit only works if generation-skipping exemption is allocated to the trust when it is funded, giving it an inclusion ratio of zero. Once that is done, the trust and everything it earns can pass to grandchildren and beyond without a further generation-skipping charge.
Practitioners often call a fully exempt, long-lived version a dynasty trust. Funding early is the whole game, because exemption is measured against value at the moment of transfer.
Putting $5,000,000 of shares into an exempt trust and letting them grow to $30,000,000 shelters the full $30,000,000, whereas waiting until the shares are worth $30,000,000 would consume far more exemption than most people have. The trade-off is control and flexibility.
Assets are locked into a structure governed by a deed written years earlier, and family circumstances change in ways no drafter can predict, which is why modern trusts often include a trust protector who can adapt terms within limits.
In practice
Real-world examples.
Example
A pharmacy chain founder settles her holding company shares into a generation-skipping trust in the year she launches a second region. The shares are valued at $4,000,000 at the time, and the trust later holds a business worth ten times that with no additional generation-skipping tax due.
Example
A father worried about his son's second marriage funds a generation-skipping trust rather than making an outright gift. His son receives the income and the trustee can meet capital needs, but the underlying assets stay ring-fenced for the grandchildren.
Example
A trustee receives a request from a beneficiary to buy a holiday home outright from trust capital. Because an unrestricted right to capital would drag the assets back into the beneficiary's estate, the trustee instead has the trust buy the property and grant a licence to occupy.
Think of it
“Generation-skipping trust skips a generation-for grandchildren while children benefit.
Formula
Calculation
The value of the structure is the estate tax avoided at the middle generation: tax saved = value of the assets in the middle generation's hands at their death x estate tax rate.
Take a founder who has $10,000,000 of unused estate and generation-skipping exemption. Route one is to leave $10,000,000 outright to her daughter, which uses the exemption and so passes tax free at first. If those assets grow to $16,000,000 by the daughter's death and her own exemption is already committed elsewhere, the estate tax is $16,000,000 x 40% = $6,400,000, leaving $9,600,000 for the grandchildren.
Route two is to put the same $10,000,000 into a generation-skipping trust and allocate the exemption to it. The daughter still draws the income for life, but the $16,000,000 is never in her estate, so no tax is charged and the full $16,000,000 reaches the grandchildren. The trust structure has saved $6,400,000 on the same underlying assets.Case study
Seen in the real world.
The following is a fictional illustration. Calderfield Tooling, an invented precision engineering business, was worth roughly $6,000,000 when its founder settled the shares into a generation-skipping trust naming her son as income beneficiary and her three grandchildren as remainder beneficiaries. She allocated exemption to the full amount at the time of funding.
Over the next twenty-two years the illustrative business expanded into medical components and was eventually valued at $41,000,000. Because the shares had never entered the son's estate, the grandchildren inherited the trust intact rather than facing a charge that, at 40%, would have exceeded $16,000,000.
The fictional family's own summary of the exercise was that the decisive move was not clever drafting but funding the trust while the business was still small and unglamorous.
Watch out
Common mistakes.
- Funding the trust but forgetting to allocate generation-skipping exemption to it, which leaves the structure exposed to the very tax it was built to avoid.
- Giving the middle generation an unrestricted right to withdraw capital, which pulls the assets straight back into their taxable estate.
- Waiting until assets have already appreciated substantially, so far more exemption is consumed than would have been needed years earlier.
Questions
People also ask.
Do the children get nothing from a generation-skipping trust?
Usually they get a great deal, including income for life and access to capital for defined needs, just not outright ownership.
How long can such a trust last?
It depends entirely on the governing state law, with some states allowing hundreds of years and others still applying a traditional perpetuities limit.
Is it only for the very wealthy?
In practice yes, because the cost and rigidity rarely make sense unless the assets are large enough to face estate tax at more than one generation.
