The Forever Vault: Dynasty Trusts & GSTT Mastery

The Forever Vault: Dynasty Trusts & GSTT Mastery

How to pass wealth down 10+ generations without paying the 40% Estate Tax toll at every transfer.

Dec 24, 2025 Code Authority: Team BMT LEGACY PLANNING

Executive Summary

  • The 40% Erosion: Without planning, the IRS takes ~40% of wealth at every generation transfer. A Dynasty Trust acts as a firewall, stopping this cycle.
  • GSTT Exemption: You must allocate your Generation-Skipping Transfer Tax (GSTT) exemption (currently ~$13.6M+) to the trust to make it permanently tax-exempt.
  • Jurisdiction Matters: You must site the trust in a state like South Dakota (SD) or Nevada (NV) that abolished the “Rule Against Perpetuities” (RAP).

The Rule Against Perpetuities (RAP)

Most states (e.g., NY, CA) force trusts to dissolve after ~90 years (or 21 years after a life in being dies). To build a true “Forever Vault,” you must use a dynasty-friendly state jurisdiction.
