Dynasty Trust: Immortality for Your Wealth

By Team BMT โ€ข Jan 31, 2026

๐Ÿ’ก Executive Summary

  • Problem: Standard Estate Planning creates a 40% tax event every time a generation dies. Wealth typically dissipates by the 3rd generation due to this “Tax Erosion.”
  • Solution: Establish a **Dynasty Trust** in a state like South Dakota or Nevada that abolished the “Rule Against Perpetuities.”
  • Result: Assets grow inside the trust forever. Children and grandchildren get income, but they never “own” the principal, so the 40% Estate Tax is never triggered again.
โš ๏ธ THE GST TAX HURDLE
The IRS imposes a “Generation-Skipping Transfer (GST) Tax” (flat 40%) if you try to skip a generation. However, you have a Lifetime GST Exemption (currently ~$13.6M). The key is to allocate this exemption to the Dynasty Trust at inception. Once allocated, the trust is exempt forever, no matter how big it grows (even to $1 Billion).

Most trusts are designed to end. A Dynasty Trust is designed to last forever. By removing the assets from the tax system permanently, you create a “Family Bank” that funds education, business ventures, and lifestyle for generations unborn, protected from creditors, divorce, and the IRS.

๐Ÿง Core Mechanic: Rule Against Perpetuities (RAP)
Old English law (RAP) said a trust must end ~21 years after the death of the last beneficiary alive at its creation (roughly 90 years). States like South Dakota repealed this. In these states, a trust can legally last for 365 years or even forever.
