The Roth Conversion Strategy Affluent Investors Over 60 Are Using to Empty Their 401(k)s

Key numbers: a married couple can convert roughly $129,000/year (≈$1.29M over 10 years) while keeping MAGI below the ~$218,000 IRMAA trigger, paying ~22–24% marginal federal tax (~$31k/year) to avoid a projected ~$160k first-year RMD on a $4M balance at age 75. SECURE 2.0 delays RMDs to age 75 for those born 1960+, creating a 10–12 year low-income window to execute Roth conversions, which can materially reduce future ordinary-income taxation and Social Security taxation. Strategy risks include the IRMAA two-year lookback and realized capital gains counting toward MAGI; the article recommends using dedicated retirement-planning tools or fee-only advisors to model multi-year conversion ladders.

Analysis

The practical fallout is not just on retiree balance sheets but on service economics across the wealth ecosystem. Advisors and platform vendors who can automate year-by-year MAGI forecasting and coordinate capital-gains realization will capture recurring advisory fees and higher wallet share; custodians who make IRA-roll processing frictionless will see stickier AUA even as tax-free growth reduces future taxable-event flows. Conversely, index-linked taxable-brokerage revenue that relies on realized-gain activity could compress over a multi-year horizon as more pre-RMD distributions migrate into Roth wrappers.

Key risks are policy and cadence rather than market direction. A single legislative tweak to IRMAA lookbacks, RMD rules, or tax-rate schedules can vaporize the arbitrage and create stop-loss selling across advisors and software vendors that front-ran client conversions; that outcome is a medium-term (6–36 month) tail risk we should price into positions. Operationally, the two-year Medicare premium lookback and interaction with realized capital gains create concentrated calendar-year income spikes that can amplify short-term tax volatility for clients and generate episodic demand spikes for tax-prep and advisory platforms.

From a positioning perspective, favor providers that sell annualized software or platform subscriptions and advisor-facing workflow tools over single-sale consulting models — recurring revenue buys time for clients to execute multi-year conversion ladders. Hedge policy and sequencing risk with conservative option structures or by shorting exposed legacy tax-service providers whose margins depend on ad-hoc, one-off conversions rather than platformized client-advice revenue.

Key Decisions for Investors

• Long INTU (Intuit) 6–18 months: buy a synthetic long via 12-month ATM call spread (buy 1x 12-month ATM call, sell 1x 12-month OTM call) to capture increased demand for tax-planning tools. Risk/reward: limited downside (-premium), capped upside; rationale: recurring subscription leverage to higher prep/advisor engagement; hedge policy risk with a 12-month protective put at ~10% OTM.
• Long ENV (Envestnet) 3–12 months: buy shares (or 9–12 month call options) to play advisor-platform adoption for conversion modeling and billing automation. Risk/reward: direct equity exposure if advisor AUM flows stall; catalyst: year-end tax-planning season and Q1 conversion activity spikes.
• Long SCHW (Charles Schwab) 6–24 months: accumulate shares with a 6–12 month protective put to benefit from incremental IRA custody flows and lower friction rollovers. Risk/reward: benefits from AUA growth vs. NII sensitivity to rates; use put to cap short-term drawdown if rates move adversely.
• Tactical hedge — short H&R Block (HRB) or buy a put 3–9 months: target legacy, volume-dependent tax-prep models that could lose share to automated planning platforms. Risk/reward: if conversion work migrates to advisor-platform ecosystems, HRB faces margin compression; this is a near-term (tax-season) tactical trade.
