Legacy’s Guide on Trust Planning and Roth Conversions
How Coordinated Design Can Reduce Multi-Million-Dollar Family Tax Exposure
This guide is designed for families with approximately $5–10 million in total household assets. It explains why trusts and Roth conversions should be planned together, and how doing so can materially reduce lifetime and legacy income taxes.
The Core Planning Opportunity
Under current SECURE Act rules, most non-spouse beneficiaries must withdraw inherited retirement accounts within 10 years. A surviving spouse, however, may stretch distributions over her life expectancy. This spouse lifetime stretch is the single largest tax deferral opportunity in multi-generational planning.
Why Roth Conversions Matter
Without Roth conversions, large traditional IRAs are often inherited by children during their peak earning years, pushing them into the highest tax brackets. Strategic Roth conversions during the spouse’s lifetime can shift taxation to lower brackets, eliminate future bracket compression, and allow assets to pass tax-free to heirs.
Roth vs. No Roth: Tax Comparison
The chart below illustrates a simplified comparison:
– No Roth Conversion: Approximately $4.0M in total family income taxes
– With Strategic Roth Conversions: Approximately $2.4M in total family income taxes
Although some tax is paid earlier in the Roth scenario, it is paid at lower rates and prevents taxation on decades of future growth. The economic benefit often exceeds $2–3 million for families in this asset range.
Bottom Line
Trusts provide control and protection. Roth conversions change the tax outcome. When coordinated properly during the surviving spouse’s lifetime, families can significantly reduce long-term tax exposure while preserving flexibility and asset protection for the next generation.
