If you’ve spent 25 or 30 years in corporate America, there’s a good chance you’ve accumulated something most people would consider a wonderful problem:
A very large tax-deferred retirement account.
Maybe it’s $1 million.
Maybe $2 million.
Maybe considerably more.
You did exactly what you were supposed to do. Maxed the 401(k). Collected the company match. Invested consistently. Let compounding do its job.
But eventually, the IRS wants its share.
Withdrawals from traditional retirement accounts are generally taxable as ordinary income, and required minimum distributions can eventually force money out whether you need the income or not.
That’s one reason Roth conversions become interesting around retirement.
But there’s a lesser-known strategy that sophisticated investors should at least understand.
Suppose you roll a large corporate 401(k) into a traditional IRA and invest a portion in an eligible illiquid private investment.
Because that ownership interest may have limited liquidity, marketability and control, an independent qualified appraiser may determine its fair market value is lower than its underlying asset value.
Consider a hypothetical $500,000 investment.
If an independent appraisal supported a fair market value of $300,000, converting that interest to a Roth could potentially create taxable income based on the $300,000 fair market value, rather than $500,000.
At a hypothetical 32% federal tax rate, that’s the difference between:
$160,000 of conversion tax and $96,000.
A $64,000 difference today.
Now zoom out 20 years.
If that $64,000 remained invested elsewhere and compounded at 8%, it would grow to approximately $298,000.
Meanwhile, the investment now inside the Roth could continue compounding, with qualified Roth withdrawals potentially tax-free.
That’s why I find this strategy so interesting for someone leaving corporate America with a substantial retirement balance.
You may be entering a rare planning window: your salary has disappeared or declined, your retirement assets are substantial, and you may have decades of compounding still ahead of you.
But this is absolutely not a DIY tax trick.
The investment must be appropriate. Any valuation discount needs to be supported by an independent, qualified appraisal. Roth conversion rules still apply. And the tax consequences need to be evaluated based on your individual circumstances.
For someone who spent 30 years accumulating a large retirement account, the question shouldn’t only be:
“How should I invest this money?”
It should also be:
“What is the most tax-efficient structure for the next 20 or 30 years?”
That may prove to be the more valuable question.
