The $4 Million Roth Conversion Strategy
How a Smart Tax Move Helped One Couple Retire Earlier — and Wealthier
What if you could add $4 million to your after-tax retirement wealth — without taking on more investment risk?
For one high-income couple in their 30s, a well-timed Roth conversion strategy made exactly that difference.
In this post, we’ll walk through the numbers, the strategies compared, and the tax insights that helped unlock a major advantage.
The Couple’s Starting Point
- Age: 39 (married couple)
- Assets:
- $1,000,000 in Traditional IRAs
- $3,000,000 in taxable brokerage accounts
- Tax Bracket: 37% (while working)
- Retirement Plan: Retire early at 45 and start withdrawals immediately
- Goal: Maximize after-tax wealth through life expectancy (age 85)
The Three Strategies Compared
1. Do Nothing – Keep the Traditional IRA
- No Roth conversions
- Withdraw in retirement and pay income tax later
- Subject to Required Minimum Distributions (RMDs) starting at age 75
2. Convert Everything Now – All at 37%
- Convert the entire $1M IRA now
- Pay ~$370,000 in taxes from the taxable account
- All future growth becomes tax-free inside a Roth IRA
3. Blended Approach – Some Now, Most Later
- Convert 10% now at 37% while working (Done strategically, when market dips)
- Convert 90% later at 24% during the first 5 years of early retirement
- Taxes paid from taxable assets
The Results at Age 85 (After-Tax Net Worth)
Strategy | After-Tax Net Worth at Age 85 |
---|---|
Do Nothing (Traditional IRA) | $50.7 million |
Full Roth Conversion at 37% | $52.9 million |
Blended Roth Strategy | $55.1 million |
💡 The Roth strategy created a $4.4 million boost in after-tax wealth compared to doing nothing.
Why This Strategy Works
- Bracket Arbitrage: Convert more in low-income years to reduce the average tax rate on IRA assets
- Tax-Free Growth: Once converted, Roth IRAs grow tax-free and can be withdrawn tax-free in retirement
- No RMDs: Roth IRAs aren’t subject to required distributions during your lifetime
- Estate Planning Friendly: Roth IRAs pass to heirs income-tax-free, and taxable assets receive a step-up in basis
What It Means for You
If you're a high-income professional or business owner planning to retire early — or expecting lower-income years ahead — this kind of Roth planning could make a meaningful difference.
But the right approach depends on:
- Your income trajectory
- Your spending needs
- Your portfolio mix
- And your long-term goals
