The Dynasty Trust: Beating the “Three Generation Curse”

By Team BMT Dec 23, 2025

💡 Executive Summary

  • Problem: Standard wealth transfer is taxed at every generation (40% erosion per death).
  • Solution: A Dynasty Trust sits in a “Trust Haven” state to avoid the Rule Against Perpetuities (RAP).
  • Result: Wealth compounds tax-free for 365 years+ (or forever), bypassing transfer taxes for G2, G3, G4…
⚠️ JURISDICTION MATTERS
Most states (like CA/NY) force trusts to end after ~90 years (RAP). To create a true Dynasty Trust, you must situs the trust in South Dakota, Delaware, or Nevada, even if you don’t live there.

“Shirtsleeves to shirtsleeves in three generations” isn’t just about spending habits; it’s about tax erosion. The Dynasty Trust is the legal fortress that stops the IRS from taking a 40% toll at every generational checkpoint.

🧐 Core Definition: GST Tax
The Generation-Skipping Transfer Tax (GSTT) is a flat 40% penalty on top of Estate Tax if you give money to grandkids. A Dynasty Trust uses your GST Exemption to immunize assets from this tax forever.

The “Trust Haven” Advantage

Feature Standard State (e.g., CA) Trust Haven (e.g., SD)
Lifespan Must End (~90 Years) Perpetual (Forever)
State Income Tax Up to 13.3% 0% Tax
Asset Protection Weak (Exception Creditors) Strong (Domestic AP)
“A Dynasty Trust does not mean ‘ruling from the grave.’ It means ‘protecting from the grave.’ Your heirs get the benefit of the wealth without the burden of the tax.”
