The Roth Conversion Mistakes That Could Cost You Thousands in Retirement

Leibel Sternbach discusses his upcoming Amazon book, The 30-Day Roth Conversion Handbook, explaining how it helps people decide whether a Roth conversion makes sense and how to execute conversions efficiently. He describes the key “levers” involved—timing and amount converted each year, tax-return strategy, and leveraging markets and the tax code—to minimize taxes now and later. The conversation focuses on how required minimum distributions can grow dramatically in a person’s 80s and 90s because IRS formulas are designed to drain retirement accounts, creating large taxable income even when the money isn’t needed. Sternbach also explains “tax bombs” on a tax return, illustrating how interest from CDs, high-yield savings, short-term trading, and dividend funds can push a low-income retiree into high taxable income, affecting the effective tax rate of Roth conversions.
