You have worked hard to build your wealth, and naturally, you want it to benefit not only your children but future generations as well. After all, you are not just passing on assets–you are entrusting them with your legacy. While a standard trust can provide protection during your lifetime, a dynasty trust can help safeguard your estate for decades beyond it.
What should you know about dynasty trusts?
A dynasty trust is a long-term irrevocable arrangement that facilitates the transfer of assets from one generation to the next. Once you, the grantor, fund the trust, you are generally not allowed to change the terms and will have no control over the assets. This rule also applies to all future beneficiaries, effectively protecting your legacy for generations to come.
Dynasty trusts, when properly structured, can also shield assets from a beneficiary’s creditors and minimize estate taxes or generation-skipping transfer (GST) taxes for as long as the assets remain within the structure.
How long can a dynasty trust last?
What sets a dynasty trust apart from other types of planning tools is its duration. A typical revocable living trust generally lasts only as long as the grantor is alive or until the assets are distributed. Dynasty trusts can last for perpetuity, depending on state law. In Washington, the law allows trusts to last for up to 150 years, a timeframe that enables multigenerational planning.
When to consider a dynasty trust?
There is typically no minimum amount required to establish a dynasty trust. Still, this type of arrangement mostly benefits families with significant or appreciating assets who want to protect wealth for multiple generations. For instance, the Washington estate tax exclusion in 2026 is $3,076,000. If your estate nears or exceeds this amount, a dynasty trust would be a strategic choice.
Dynasty trusts can be powerful tools for long-term planning. However, they are irrevocable and complex. It is important to carefully evaluate your desire for control against the lasting benefits of generational security before you establish one.
