Capital gains taxes can be a huge obstacle for retirees. In a recent Reddit post, I read about a 55-year-old preparing for retirement in the next five years. However, he was facing a problem that isn’t all that rare:
He has accumulated $2.5M in Apple stock that was purchased three decades ago. Now, it is almost all capital gains. He wants to draw on this income to fund his first few years of retirement, but doing so would count as Modified Adjusted Gross Income (MAGI).
This would likely trigger higher taxes. So, how does he get around it? Let’s look at his situation and see what others can learn from it.
| Filing Status | Long-Term Capital Gains Tax Rate | Taxable Income in 2025 |
|---|---|---|
| Single | 0% | $0 – $48,350 |
| Single | 15% | $48,351 – $533,400 |
| Single | 20% | $533,401 or more |
| Married Filing Jointly | 0% | $0 – $96,700 |
| Married Filing Jointly | 15% | $96,701 – $600,050 |
| Married Filing Jointly | 20% | $600,051 or more |
Insights From the ChubbyFIRE Community
This dilemma recently sparked a massive debate on the r/ChubbyFIRE Reddit community, where market veterans and early retirement enthusiasts chimed in on the logistics of unwinding a single-stock position. Many community members pointed out that while a $2.5 million “problem” is an enviable position to be in, the execution risks are high. When your net worth is heavily concentrated in a single tech giant, a sudden market downturn right at the start of your retirement window can permanently derail your plans—a phenomenon known as sequence of returns risk.
Capital Gain’s Impact on MAGI
This poster’s main issue is that he plans on selling a large portion of this appreciated stock, which would increase his MAGI. This would result in higher taxes and likely push him into a higher Medicare bracket.
Neither of those factors is a thing to scoff at.
What Can He Do?
There are some things he can do to help lower his bill. It’s important to note that this tax bill cannot be avoided completely. He will need to pay something on these capital gains. However, there are a few ways he can lower or spread out his tax burden:
- Spread out gains: By avoiding selling all the stock at once, he could spread out his tax burden and stay under IRMAA thresholds.
- Leverage charitable giving: Another option is to give to a donor-advised fund, which would lower his overall tax bill.
- Use tax-advantaged accounts: He could consider a blend of early IRA withdrawals or Roth conversions to reduce taxes in the future, potentially offsetting taxes from his Apple stocks.
- Explore specialized investments: He could also use a Qualified Opportunity Fund to reinvest his Apply stock into a different investment opportunity, potentially delaying his tax burden. For instance, many invest their money in real estate.
- Plan ahead for RMDs: While it is still some years out, he should go ahead and start planning for RMDs, which will help him minimize future faces.
These five strategies could all lower his tax bill and Medicare costs. Which ones make sense to him depends on his preferences and retirement plans.
The Corporate Stock Account Alternative: NUA
If a concentrated stock position like this happens to be held within an employer-sponsored 401(k) rather than a traditional brokerage account, a highly specialized strategy called Net Unrealized Appreciation (NUA) comes into play. Under NUA rules, you can transfer the company stock out of the 401(k) into a taxable brokerage account. You only pay ordinary income tax on the original cost basis of the stock. The massive growth—the unrealized appreciation—is then taxed at the much lower long-term capital gains rate when sold, rather than the higher ordinary income tax rates that normally apply to 401(k) withdrawals. However, the execution rules are rigid, and a single mistake can void the tax advantage.
Diversifying Without Triggering a Sale: Exchange Funds
For investors holding millions in a single ticker who want to diversify without instantly triggering a massive capital gains tax bill, an Exchange Fund (not to be confused with an ETF) is a sophisticated option. In an exchange fund, multiple investors pool their concentrated stock positions from different companies into a partnership. You contribute your Apple stock, and in return, you receive a proportional share of a diversified portfolio consisting of all the contributed stocks. Because you are swapping shares rather than selling them, it is generally a tax-free event, allowing you to instantly mitigate single-stock risk while deferring your capital gains.
Why an Expert Guide Matters for This “Good Problem”
Ultimately, managing a multi-million dollar liquidity event requires balancing tax efficiency with investment risk. While the strategies outlined above are excellent jumping-off points, they represent personal opinion and broad financial education rather than personalized advice. A qualified, fiduciary financial advisor can look at your entire financial ecosystem—including your filing status, other income streams, and state-specific tax laws—to build a multi-year drawdown runway. Navigating IRMAA brackets, NIIT (Net Investment Income Tax), and tax-loss harvesting requires a chess player’s approach to wealth management.
