One of the most common questions I get from clients is what to do with a highly appreciated stock position. Whether it came from equity compensation at work or individual stocks that have grown dramatically over time, the dilemma is always the same: do you take the gains off the table, or let it ride and hope for more growth, without triggering a massive tax bill?
The good news is there are more options than most people realize.
1. Sell Shares Strategically
The obvious starting point is being thoughtful about how and when you sell.
Most people default to holding shares for over 365 days to qualify for long-term capital gains rates. That's generally smart, but it's not always the best move. In some cases, selling a short-term lot can actually be more advantageous if the gain on that lot is significantly smaller, even though the rate is higher. You're paying more on less, which can mean a lower total tax bill. This is why reviewing your specific cost basis lots matters before selling anything.
A few other strategic approaches worth considering:
- Spread sales across multiple tax years. Set a cap on how much gain you're willing to realize each year and stick to it.
- Sell more when the price dips. If the stock pulls back during the year, that's an opportunity to sell additional shares with a smaller embedded gain.
- Manage your bracket. If you can keep your total capital gains in the 15% bracket instead of the 20% bracket, that's meaningful savings over time.
- Hedge your position with a collar. A collar involves buying a put option and selling a call option simultaneously. It puts guardrails around your current position, limiting your downside while capping your upside. This gives you breathing room to sell over time without exposure to dramatic price swings. These strategies are complex and generally warrant professional management.
2. Tax Loss Harvesting
Capital losses offset capital gains dollar for dollar. If you have $10,000 in gains, $10,000 in losses wipes them out entirely.
If you want to build losses more systematically, direct indexing is worth understanding. Instead of owning one index fund, you own the individual stocks that make up an index. Because individual positions move up and down independently, you can harvest losses as specific holdings dip below their cost basis, even in years when the overall index is up. Unused losses carry forward indefinitely to offset future gains.
For larger anticipated events, like a business sale or significant stock liquidation, a long-short direct indexing strategy goes further. You're taking positions on both sides of the market, which generates losses more aggressively regardless of market direction. The tradeoff is added complexity, leverage, and higher cost. It's not for everyone, but for someone with a large capital gain on the horizon, it can be a powerful planning tool.
3. Charitable Giving
If you're charitably inclined, donating appreciated stock directly to charity is one of the most tax-efficient moves available. You avoid the capital gain entirely and receive a deduction for the full fair market value, assuming the stock has been held long-term. That's a double tax benefit in one transaction.
A few structures to know:
- Donor-Advised Fund (DAF): You contribute the stock, take the deduction in the current year, and distribute the money to charities on your own timeline. Great for bunching deductions into one high-income year.
- Charitable Remainder Trust (CRT): You receive a partial deduction upfront and an income stream for a set period, with the remainder going to charity. Useful for charitably inclined people who also want ongoing income.
- Charitable Lead Trust (CLT): The income stream goes to charity first, with the remainder returning to you or your heirs.
4. Qualified Opportunity Zones (QOZ)
A Qualified Opportunity Zone investment allows you to defer the taxable gain from a stock sale by reinvesting the gain portion into a QOZ fund within 180 days after the sale.
The rules here are evolving with the One Big Beautiful Bill Act (OBBBA), so confirm current timelines with your advisor before acting. Under the updated framework expected to take effect in 2027, the structure becomes a rolling 5-year deferral, meaning you don't owe tax on the deferred gain until five years after the investment is made. This gives you time for that capital to compound before the tax bill comes due, and ideally you'll be in a lower bracket when it does.
An additional benefit: if you hold the QOZ investment for 10 years, you receive a full step-up in basis on the growth inside the fund, meaning that appreciation is never taxed. Shorter holds receive partial step-ups of 10% at year five and 15% at year seven.
Keep in mind these investments typically carry illiquidity due to the underlying real estate. Plan not to need this capital.
5. Exchange Funds
An exchange fund allows you to contribute your concentrated stock to a partnership in exchange for an LP interest in a diversified pool of assets. After a holding period, typically seven years, you receive a diversified basket back.
This strategy doesn't eliminate taxes, it defers them, but it solves the concentration problem without a taxable sale. The catch is that funds don't always accept every stock. If the fund already holds too much of a particular company, they won't take more. You'll need to confirm eligibility before pursuing this route.
6. Section 351 Exchange
Similar in spirit to an exchange fund, a 351 exchange allows you to transfer a basket of stocks into a newly created ETF as seed capital, without triggering a taxable event. You then own shares in that ETF instead of the individual positions.
To qualify, your contribution must meet the IRS diversification rules, commonly referred to as the 25 and 50 rules. Again, this is about managing concentration rather than eliminating the tax, but doing so without a current tax bill is a meaningful advantage.
7. Gift to Family Members in Lower Tax Brackets
If you have family members in a lower tax bracket, gifting appreciated shares can be a smart move. Your cost basis and holding period carry over to the recipient, and they sell at their own tax rate, which may be significantly lower than yours.
This also serves an estate planning function. If you're approaching the estate tax exemption threshold, gifting shares now reduces the size of your taxable estate and can help you stay below the limit where a 40% estate tax kicks in.
8. Hold Until Death
For stock you don't need to sell, holding until death may be the most powerful option of all. Assets in a taxable account receive a step-up in cost basis to fair market value on the date of death. Your heirs inherit the shares as if they purchased them that day, meaning decades of appreciation can pass completely tax-free.
It's one of the most lucrative provisions in the tax code, and it's worth factoring into your long-term planning.
Wrapping It Up
A concentrated stock position is a good problem to have, but it comes with real complexity. The right strategy depends on your income, your timeline, your charitable goals, and whether you're trying to eliminate the tax, defer it, or simply manage the concentration. Most people end up using a combination of these approaches rather than any one in isolation.
Work with a financial advisor and tax professional to map out what makes sense for your specific situation before you act.
