Dynasty Trust Summary
How a Dynasty Trust Compounds Wealth Tax-Free
Without a dynasty trust, each generation pays 40% estate tax, devastating long-term wealth accumulation. With a properly funded dynasty trust and GST exemption, the same wealth compounds tax-free across centuries.
Net Annual Growth = Return % β Distribution Rate %
Trust Value at Year N = Funding Γ (1 + net growth%)^N
"Taxed Baseline" (no dynasty trust, 40% estate tax every 25 years):
After each 25-year generation: Value Γ (1 + ret%)^25 Γ 60%
Total Estate Tax Avoided = Trust Value β Taxed Baseline Value
Trust Value at Year N = Funding Γ (1 + net growth%)^N
"Taxed Baseline" (no dynasty trust, 40% estate tax every 25 years):
After each 25-year generation: Value Γ (1 + ret%)^25 Γ 60%
Total Estate Tax Avoided = Trust Value β Taxed Baseline Value
Example: $13.99M funded, 7% return, 3% distributions, 100 years
Net growth: 4% | Trust value at year 100: $709M
Taxed baseline (4 generations Γ 40% tax): $44M
$665M in estate tax avoided over 100 years
Net growth: 4% | Trust value at year 100: $709M
Taxed baseline (4 generations Γ 40% tax): $44M

Frequently Asked Questions
What is a dynasty trust and how does it avoid estate tax?
A dynasty trust is an irrevocable trust designed to last for multiple generations β avoiding estate and gift taxes at each generation. By funding it with GST (Generation-Skipping Transfer) tax exemption ($13.99M per person in 2026), the trust passes wealth to grandchildren, great-grandchildren and beyond without a 40% estate tax bite at each generation. Without dynasty trust planning, a $10M estate could be reduced to under $1.3M after four generations of 40% estate tax.
Which states allow perpetual or near-perpetual dynasty trusts?
Several states have abolished or extended their Rule Against Perpetuities: South Dakota (perpetual), Nevada (perpetual), Alaska (1,000 years), Delaware (360 years), Tennessee (360 years). Many other states allow 90-150 years. Using a favorable trust situs allows the trust to last essentially forever. The trust can hold assets in any state; the governing law determines the perpetuity period.
How does the GST exemption work in a dynasty trust?
The GST exemption ($13.99M per person, $27.98M per couple in 2026) can be allocated to the dynasty trust. Once the trust has an "inclusion ratio" of zero, all distributions to grandchildren and lower generations avoid the 40% GST tax. Without allocating GST exemption, distributions to skip persons (grandchildren and below) would be subject to an additional 40% GST tax on top of regular estate tax.
What happens to dynasty trust distributions?
Dynasty trusts typically make discretionary distributions for health, education, maintenance, and support (HEMS) to each generation's beneficiaries. The trust itself does not trigger estate tax at each generation's death. The trust can also lend money to beneficiaries, purchase life insurance, or hold family business interests. The trustee's investment and distribution decisions are critical to maximizing long-term wealth.
What are the income tax considerations for dynasty trusts?
Dynasty trusts are separate taxpaying entities (unless they qualify as grantor trusts). In 2026, trusts hit the 37% federal income tax bracket at only $15,200 of income. To minimize income tax, trustees often make distributions to beneficiaries (who are in lower brackets) rather than accumulating income in the trust. The trust may also use tax-advantaged investments or hold assets that generate minimal current income (like growth stocks).
