Dynasty Trusts and GST-Exempt Planning

How a Dynasty Trust works

1. Trust creation. An irrevocable trust is drafted for the long-duration period -- in NJ, potentially perpetual under N.J.S.A. 46:2F-91. Beneficiaries typically include the grantor's children, grandchildren, and more remote descendants.
2. Funding. The grantor makes a gift to the trust. The gift uses the grantor's lifetime gift-tax exemption. The grantor allocates GST exemption to the trust under IRC § 26322, producing an inclusion ratio of zero -- the trust is fully GST-exempt for its entire duration.
3. Investment and growth. Trust assets are invested under the trustee's management. Income and growth accumulate inside the trust without transfer tax at each generation.
4. Distributions across generations. The trustee distributes income and principal to beneficiaries under the trust's distribution standards. Distributions to grandchildren and more remote descendants don't trigger GST tax because the trust's GST exemption was fully allocated.
5. Generational transitions. When current-generation beneficiaries die, their interests don't pass through their estates (because they had only beneficial interests, not ownership). The trust continues without estate-tax events.
6. Eventual termination. If the trust contemplates eventual termination (some do; some are perpetual), termination distributions to remaining beneficiaries occur under the trust's terms.

The generation-skipping transfer (GST) tax

Under IRC §§ 2601-26641:

• Flat 40% tax on transfers that "skip" a generation -- typically grandparent-to-grandchild and more remote.
• Three types of GST transfers: direct skips (gift or bequest directly to a skip person); taxable distributions (trust distribution to a skip person); taxable terminations (interest of a non-skip person ends, leaving only skip persons).
• GST exemption under IRC § 26312 -- $15 million per individual for 20263, matching the estate-tax basic exclusion amount and indexed after 2026.
• Inclusion ratio. Calculated as 1 minus (GST exemption allocated ÷ value transferred). An inclusion ratio of 0 means the trust is fully GST-exempt; an inclusion ratio of 1 means full GST tax applies. Properly funded Dynasty Trusts have inclusion ratios of 0.
• Combined effective rate without GST planning: estate tax (40%) plus GST tax (40%) can produce combined effective rates exceeding 60%.

NJ as a dynasty-trust jurisdiction

NJ is competitive with the leading dynasty-trust jurisdictions:

• No Rule Against Perpetuities. Under N.J.S.A. 46:2F-91, NJ abolished the Rule Against Perpetuities for trusts effective 1999. NJ trusts can continue indefinitely.
• No state estate tax. NJ repealed its estate tax effective 2018.
• Asset protection. NJ generally enforces spendthrift trust protections for third-party trusts; certain other jurisdictions (for example, Nevada and South Dakota) have specific statutory frameworks for self-settled asset-protection trusts that NJ does not match. The right situs depends on the family's objectives and the specific creditor-protection question.
• Trustee jurisdiction. NJ corporate and individual trustees are well established; NJ courts have substantial experience with complex trust matters.
• Tax considerations. NJ state income tax may apply to trust income depending on trustee residency, beneficiary residency, and the source of the income; specific deductions and allocations can affect the burden. Trust-tax analysis should be coordinated with a qualified tax advisor.

Alternative dynasty jurisdictions (Delaware, South Dakota, Nevada, Alaska, Wyoming) offer competing advantages -- typically stronger asset protection, no state income tax on trust income for non-residents, and specific procedural advantages. The choice depends on the family's specific objectives.

Distribution standards and trustee structures

• HEMS (health, education, maintenance, support). Ascertainable standard providing creditor protection and tax efficiency. Most Dynasty Trusts use HEMS for beneficiary-trustee distributions.
• Broader trustee discretion. "Best interests" or unfettered discretion -- provides flexibility but limits creditor protection.
• Trust protector. Third party with limited powers to modify trust terms, change trustees, address unanticipated circumstances. Increases flexibility without compromising irrevocability.
• Co-trustee structures. Beneficiary-trustee plus independent trustee, with distribution authority typically held by the independent trustee.
• Investment direction. Some trusts use directed-trustee arrangements where investment authority is held by a separate investment advisor under N.J.S.A. 3B:31-311-type provisions.

Dynasty Trust funding strategies

• Direct gift. Outright gift using gift-tax and GST exemption.
• SLAT-funded dynasty. SLAT (see our SLAT page) drafted to allocate GST exemption and continue as a dynasty trust for descendants after the beneficiary spouse's interest ends.
• ILIT as dynasty trust. ILIT (see our ILIT page) holds life insurance payable to a continuing dynasty trust at the insured's death.
• Sale to IDGT. Grantor sells appreciated assets to an Intentionally Defective Grantor Trust (see our IDGT page) which is itself structured as a dynasty trust. The promissory-note payment back to the grantor returns some value; the appreciation above the AFR accrues to the dynasty trust.
• GRAT-to-Dynasty. GRAT remainder (see our GRAT page) pays into a continuing dynasty trust at the end of the GRAT term.

Considerations across generations

• Distribution patterns evolve. The first generation may receive substantial distributions; later generations may receive less per capita as the family grows. Trust drafting should anticipate this.
• Family governance. Multi-generational trusts often include family-governance provisions -- beneficiary advisory committees, family meetings, mission statements, dispute-resolution procedures.
• Trustee succession. Long-duration trusts need trustee-succession mechanisms that don't depend on specific individuals. Corporate trustees provide longevity; trust-protector provisions provide flexibility.
• State-law changes. Tax laws, perpetuities rules, and trust statutes can change over the trust's duration. Drafting should include provisions for adapting to changes in applicable law.
• Modification and decanting. New Jersey has no decanting statute; a trustee with broad discretionary distribution authority may decant under New Jersey common law (Wiedenmayer v. Johnson, 106 N.J. Super. 161 (App. Div. 1969)1), allowing the trustee to transfer assets to a new trust with updated terms. This provides important flexibility for long-duration trusts.

Current GST exemption planning

The 2026 GST exemption is $15 million per individual1 and indexed after 2026. Funding Dynasty Trusts with proper GST allocation can lock in GST-exempt treatment for the trust's entire duration, allowing future appreciation to compound outside additional generation-skipping transfer tax. For families with substantial wealth to commit to multi-generational planning, the work is modeling the allocation, choosing the right trustee and situs, and drafting enough administrative flexibility for decades of legal and family change.

When a Dynasty Trust is -- and is not -- the right tool

A Dynasty Trust is not the answer for every family, and a responsible analysis says so plainly. The structure earns its keep in a specific zone: families with wealth meaningfully above the federal exemption who genuinely intend to hold and grow assets across multiple generations rather than distribute them outright to children. Where that multi-generational intent and the wealth to support it are both present, the dynasty trust does work that outright gifts and ordinary estate planning cannot. Where they are not, the complexity and cost are hard to justify.

The honest cautions run the other way:

• Below the wealth floor. For a family whose combined assets sit comfortably below the federal exemption and are expected to stay there, there is no generation-skipping tax to plan around. The exemption shelters the transfer already, and the cost and multi-decade administration of a perpetual trust outweigh a benefit the family will never use. Simpler planning is the better path.
• Loss of control and flexibility. A Dynasty Trust is irrevocable and, in NJ, potentially perpetual. The grantor gives up the ability to reclaim the assets or freely rewrite the terms, and commits the family to a structure that will outlive everyone who designed it. Trust-protector and decanting provisions soften this, but irrevocability is the entire point -- a grantor who wants to retain control is not a candidate.
• Families who prefer outright distributions. Some families want their children and grandchildren to receive assets outright, own them directly, and make their own choices -- accepting the transfer-tax and creditor exposure that comes with ownership. For those families the dynasty trust's held-in-trust design works against their values rather than for them, and forcing the structure creates friction it was never meant to cause.
• No appetite for long-horizon administration. Perpetual trusts need trustee succession, ongoing accounting, and the willingness to manage a structure for decades. Families unwilling to sustain that administration -- or to pay for it -- are better served by planning with a shorter horizon.

The point of listing these is not to talk anyone out of a Dynasty Trust. It is to be candid that the structure is a deliberate trade -- present control and outright ownership surrendered in exchange for multi-generational transfer- tax efficiency -- and that the trade is worth making only when the wealth, the family's intent, and the tolerance for long-duration administration all line up. Where they do not, we will tell you so.

How we help: We model the family lines, GST allocation, funding assets, trust situs, trustee succession, distribution standards, trust-protector powers, decanting authority, and termination rules that must remain workable across generations. A plan accepted by the firm is bespoke trust drafting, not a dynasty-trust template. Describe the generations and assets the trust would need to serve.
