Wealth Across Generations, Protected by Design

The greatest threat to multigenerational wealth is not market volatility or poor investment selection — it is the federal transfer tax system, which imposes a flat 40% tax rate on all estate and gift transfers above the exemption threshold. The passage of the One Big Beautiful Bill Act (OBBBA) on July 4, 2025 permanently set the federal estate, gift, and generation-skipping transfer (GST) tax exemption at $15 million per individual — indexed for inflation beginning in 2027 — creating the most favorable wealth transfer environment in modern U.S. tax history. Yet favorable conditions are not permanent guarantees: future legislative change remains a structural risk that every multigenerational wealth strategy must account for from the outset. This book examines the full architecture of multigenerational estate tax strategy: the structural mechanics of the Generation-Skipping Trust (GST), which eliminates one layer of transfer taxation by passing wealth directly to grandchildren; the Dynasty Trust, which severs wealth from the federal transfer tax system entirely — allowing assets to compound across 100 years or more in perpetuity in favorable jurisdictions — never triggering estate or GST tax as long as the trust remains intact and beneficiaries hold no direct ownership. It maps the strategic application of complementary instruments: the Spousal Lifetime Access Trust (SLAT), which locks in today's elevated exemptions while preserving spousal access; the Intentionally Defective Grantor Trust (IDGT), which mirrors SLAT benefits for single individuals; and Grantor Retained Annuity Trusts (GRATs), which transfer appreciating assets to heirs at minimal gift tax cost. The book also addresses GST exemption allocation — a technically precise discipline that determines whether a trust achieves full multigenerational tax efficiency or inadvertently exposes future distributions to the 40% GST rate.
