A Caller’s Dad Turned $22,000 Into $1 Million on a Single Stock. Now the Family Faces a $150,000 Tax Decision

On a recent segment of Ramsey’s Everyday Millionaires, a caller named Seth, 52, from Boca Raton, opened with a line most investors only fantasize about: “We kind of hit the stock lottery, Dave.”

His 84-year-old father, now in memory care with Alzheimer’s dementia, once bought 1,000 shares of a single company at $22 per share. Those shares now trade for over $1,000 apiece, turning a $22,000 stake into roughly $1 million. The rest of the estate includes an $800,000 to $900,000 IRA and two Morgan Stanley accounts, bringing the total to just under $5 million.

The family got lucky. The real question is what to do next. Sell the position now and the IRS collects an estimated $150,000 in capital gains taxes. Hold until the father passes and that tax bill can legally disappear. That is the pivot the entire conversation turns on.

The Verdict: The Host Is Right on Risk, but the Framing Is Incomplete

The host was blunt: “Whatever that company does, so does the million dollars.” And if “the stock goes in half, then you lost $500,000.” That is a real risk. But treating this as a binary sell-or-hold decision misses the tool that makes patient inaction powerful here: the step-up in basis.

Here is the mechanic in plain English. When someone dies holding appreciated stock, the cost basis resets to the market value on the date of death. Seth put it clearly: “if we keep it and then he passes away, we then get that new step-up basis”. The heirs inherit the shares as if they paid today’s price. Sell the next day at that price and the taxable gain is essentially zero. Decades of appreciation vanish for income tax purposes.

Long-term capital gains for high-income households can hit 20% federal, plus the 3.8% Net Investment Income Tax, plus state tax. That stack is how a $1 million sale generates the $150,000 hit the host called a $150,000 decision. Waiting for the step-up could erase most of it. On a sub-$5 million estate, the $15 million federal estate exclusion for 2026 decedents means no federal estate tax either.

Concentration Risk Cuts the Other Way

One-stock portfolios are how fortunes get both made and unmade. Seth’s father held what looks like a classic long-term compounder. Microsoft (NASDAQ:MSFT | MSFT Price Prediction) is the archetype: the stock returned roughly 704% over the past decade. Yet even Microsoft is down about 20% over the past year and down 16% year to date, trading near $399 after touching $551 in the past 52 weeks. A best-in-class name with 46% operating margins and a $2.99 trillion market cap can still cough up six figures of value in months.

The host’s warning is grounded in real cases. Fraud, a product misstep, or a broad tech drawdown can slice a concentrated position quickly. The step-up only rewards patience if the share price cooperates while you wait.

Seth’s Middle Ground

Seth’s counter was practical. The family discussed selling only 20% to 25% of the position, roughly $200,000 worth, which he said would trim the tax bill to around $30,000 to $40,000. That partial sale accomplishes two things at once. It de-risks the concentration by moving a chunk into diversified holdings, and it preserves the step-up on the remaining shares. If the stock craters tomorrow, they still kept most of the position for the basis reset. If it holds up, they only surrendered a small slice of future gain.

That is what the host’s binary framing misses. The variable that decides everything is how much to sell. The right slice depends on the family’s tolerance for a single-name drawdown, the father’s life expectancy, and the tax bracket in the year of sale.

What to Do With This

If you or a parent are sitting on a concentrated winner with a low basis, take three concrete steps:

1. Pull the actual cost basis and unrealized gain from the brokerage. You cannot model any decision without the exact numbers on the statement.
2. Model partial sales in tranches. Ask what selling 10%, 25%, and 50% each does to the tax bill and to the percentage of net worth still tied to one company.
3. Loop in an estate attorney and a CPA before acting. The step-up in basis, the $15 million 2026 estate exclusion, gifting, and donating appreciated shares to charity all interact in ways worth pricing out for your specific situation.

The step-up in basis is one of the few remaining giveaways in the tax code. Ignoring it costs real money. So does letting one stock decide your net worth.
