Most trusts have a defined termination date. Under the common law “rule against perpetuities,” a trust generally must terminate and distribute its assets within a set period after the death of everyone living when it was created, typically about 21 years. A dynasty trust is designed to get around that limit.
An experienced estate planning attorney can determine the right form of trust for your family’s needs, including the possibility that a dynasty trust, which holds and manages assets for multiple generations, is appropriate.
How Dynasty Trusts Work in Illinois
A dynasty trust is irrevocable and structured to remain intact for multiple generations, passing wealth to children, grandchildren, and beyond. Illinois is one of the states that allows a properly-drafted trust to opt out of the rule against perpetuities entirely. The Illinois Trust Code allows certain qualified perpetual trusts to continue for an unlimited number of generations rather than requiring them to be broken up and redistributed with each new generation.
A dynasty trust’s core advantage is that the assets it holds are owned by the trust, not by any individual beneficiary. This shields the assets from risks like:
- Beneficiaries’ creditors
- Claims in a beneficiary’s divorce
- Being counted as part of a beneficiary’s taxable estate upon death
- Repeated exposure to estate tax requirements
Avoiding Generation-Skipping Transfer Taxes
The federal generation-skipping transfer (GST) tax is triggered by transfers that skip a generation, such as from a grandparent to a grandchild, in addition to ordinary gift and estate taxes. The federal gift, estate, and GST tax exemption is $15 million per individual as of 2026, or $30 million per married couple. Funded with a donor’s GST exemption, a dynasty trust allows the exemption to protect every future transfer the trust makes to subsequent generations rather than requiring GST tax to be paid each time assets move down a generation.
In Illinois, the tax implications are particularly important. The state imposes its own estate tax with a $4 million exemption per individual, independent of federal transfer taxes. In Illinois, if the estate is valued above $4 million, the entire estate is subject to estate taxes, not just the portion above the $4 million exemption. The gap between state and federal exemptions, about $11 million per individual, means a dynasty trust can make a big difference for Illinois families whose estates are below the federal exemption but large enough to trigger Illinois’ estate tax.
Who Should Consider a Dynasty Trust
Anyone who wants to keep family assets, a business, or real estate within the family across generations while limiting exposure to taxes, creditors, and divorce settlements is a key candidate for a dynasty trust. That can include a family business owner, a family with significant real estate holdings, or parents concerned that an inheritance could be prey in a future divorce. It is not exclusive to the ultra-wealthy.
Establishing a Dynasty Trust Correctly
Because a dynasty trust is irrevocable and meant to last indefinitely, drafting errors can be difficult or impossible to correct. Multigenerational trust planning is a complex process, since decisions about trustee succession, distribution standards, and state tax exposure must hold up decades or centuries after the trust is created. It must also be funded correctly and, for GST protection, coordinated with the available exemption at the time of funding.
