After‑Tax Strategies for Early Investors with Concentrated Stock

Key takeaways

• Investors with IPO securities benefit most when concentration risk and capital gains exposure are considered early.¹
• Managing concentrated stock from an IPO typically requires multiple after-tax strategies, combining exclusion, deferral, offsetting, and hedging rather than relying on a single solution.
• There is no one size fits all approach to concentrated stock risk, as the right strategy depends on lock up agreements and restrictions, as well as each investor’s tax profile, liquidity needs, and long-term goals.

2026 is the year of high-profile tech IPOs, with valuations at eye-popping levels. For early investors holding low-basis shares in these companies, an IPO brings opportunity but also the challenge of managing concentration risk without incurring an oversized capital gains bill. This may be a champagne problem, but it needs to be solved nevertheless and can be addressed through thoughtful planning. We lay out an after-tax wealth framework for managing concentrated stock, organized around four principles: exclude the gain when possible, defer it when exclusion is not possible, offset it through loss harvesting, and hedge and diversify concentration risk when appropriate². There is no single best strategy for managing the risk and potential tax impact of a concentrated position, which is why effective pre-IPO planning for early investors requires careful coordination. In the case study that follows, we walk through the key questions, resources, and considerations advisors and investors should weigh when navigating a highly appreciated stock.

Case Study: What Should Early Investors Consider Before an IPO?

Fifteen years ago, Jane Smith took a chance on an early-stage Silicon Valley tech startup, writing a $500k check at a time when the company was little more than a pitch deck. Today, that bet is worth $20 million. As the company prepares to go public, Jane asks that question every successful early investor eventually faces: is it time to diversify?

A partner at a large law firm and no stranger to risk, Jane is a believer in capital markets and comfortable with volatility. She seeks a diversified portfolio and dislikes the idea of her financial future hinging on the fortunes of a single company. The run-up in stock price opened a door she hadn't previously contemplated: stepping back from her demanding legal practice and traveling in a way that her career had long crowded out.

Jane sits down with her financial advisor, George Williams, with four clear goals in mind:

1. Diversify her concentrated equity position³.
2. Manage the tax impact of the substantial unrealized gain.
3. Reposition her portfolio's mission from wealth accumulation to support for a comfortable retirement.
4. Share her good fortune with charitable organizations.

As a first step toward achieving these goals, George walks Jane through the after-tax portfolio construction framework he uses with concentrated-stock clients built around the four principles: exclude, defer, offset, and hedge/diversify.

Exclude: Using QSBS to Reduce Federal Capital Gains

George explains a provision called Qualified Small Business Stock, or QSBS. Originally designed by Congress to encourage investment in early-stage American companies, QSBS allows qualifying shareholders, often early backers of tech and manufacturing businesses, to exclude a capital gain of up to $10 million from federal tax. For Jane, that could mean selling roughly half her position without owing a dime in federal capital gains tax, a powerful first step toward diversification⁴.

When Jane asked George what else she might need to know, he advised her to confirm with her tax advisor that her shares meet the QSBS qualification requirements. George mentions her California residency means that she may need to pay state capital gains. However, the federal exclusion does the heavy lifting, knocking out the largest portion of the tax bill.

Defer: Charitable Remainder Trusts (CRUTs) after an IPO

Having worked with Jane for many years, George knows how important charitable giving is to her. He recommends that, once the lockup period expires, Jane considers deferring tax on a portion of her concentrated position by contributing it to a Charitable Remainder Unitrust (CRUT) and immediately selling it.

Here's how it works: As soon as Jane transfers $5 million in shares to the CRUT, she receives an immediate charitable income tax deduction equal to the present value of the remainder interest that will eventually pass to charity. This is a meaningful benefit, given the high-bracket ordinary income she earns as a law firm partner. The CRUT, itself a tax-exempt entity, can then sell those shares without triggering an immediate capital gain. Jane receives a 5% annual distribution from the trust, and the embedded gain is recognized gradually as distributions are paid out. Because CRUT distributions follow a strict tier-ordering rule, the taxable character of each payment flows out worst to best: ordinary income first, then short-term capital gains, then long-term capital gains, and finally return of principal.

That tier-ordering drives George's asset allocation recommendation inside the trust. He steers Jane to minimize her allocation towards fixed income in the CRUT, since the interest income would be paid out as ordinary income, the worst possible tax treatment under the CRUT's distribution rules. Instead, George recommends a low-cost S&P 500 ETF as the core holding, giving Jane diversified U.S. equity exposure without producing meaningful ordinary income.

Offset: Harvesting losses with tax-aware Long/Short Strategies

QSBS solves the federal capital gain tax issue on the first half of Jane's position, and the CRUT defers another portion of the gain on the second half. But two tax bills remain: the California state capital gains tax on the QSBS sale, and the capital gain distributions that will flow out of the CRUT each year. To address them, George turns to the third pillar of the framework: offset.

His recommendation is to put $6 million of the QSBS proceeds into a tax-aware long/short strategy, which relaxes the long-only constraint found in traditional equity portfolios.

The long/short portfolio manager can express investment views by overweighting stocks with characteristics the manager favors and shorting stocks with characteristics the manager wants to underweight, all while maintaining beta-1 market exposure. With positions on both sides of the book, the manager can systematically harvest capital losses as part of the ongoing risk management process.

For Jane, those realized losses can be used to help offset the California state capital gains tax on the initial QSBS sale and absorb the gains distributed from the CRUT to her Schedule D on tax form 1040 over time, mitigating two ongoing tax drags.

Hedge & Diversify: Reducing single‑stock risk with option strategies and state-specific Munis

With the remaining $5 million of shares, George turns to the fourth and final principle of the framework: hedge and diversify. Rather than sell the stock outright and triggering another round of taxable gains, George suggests writing qualified covered calls on the concentrated stock to dampen the volatility in the underlying stock.

We highlight two outcomes from a tax perspective that may happen when selling a qualified covered call:

• Scenario A: Stock rallies. To avoid having Jane's shares called away, George closes the existing call and writes a new one with a higher strike price and a later expiration date (commonly referred to as 'rolling up and out'). The cost of closing the original call typically generates a realized loss. Those realized option losses can be used to tax-neutrally trim additional shares, gradually reducing concentration without a net tax bill.
• Scenario B: Stock declines. Jane’s options make money that helps cushion the stock’s drawdown. These option gains are taxed at the short-term capital gains rate. However, since the tax-aware long/short portfolio may generate net short-term losses, those short-term losses, first go towards offsetting short-term capital gains and then may offset additional long-term cap gains from the sale of the stock.

Lastly, as part of the diversification plan and beyond the $6 million allocated to the tax-aware long/short strategy, George recommends Jane deploy the remaining $4 million of QSBS proceeds into California-specific municipal bonds. Because California Munis are exempt from both federal and California state income tax, they give Jane a tax-efficient source of income while diversifying her portfolio, adding a high-quality, fixed-income sleeve that complements the equity-heavy structure of the rest of her assets.

Putting the IPO After‑Tax Framework into action

Using the framework of exclude, defer, offset, hedge, and diversify, George was able to help Jane accomplish each of her goals. We recap the framework and its recommendations for Jane below:

Jane walked into George's office with a $20 million concentrated stock position, a looming IPO, and four goals: diversify the position, manage the tax impact, reposition her portfolio for retirement, and position her assets to give back to charity. She walks out with a coordinated plan she can implement once restrictions expire that meaningfully addresses all four.

There is no single best strategy for managing a concentrated position. However, by calibrating the exclude, defer, offset, hedge, and diversify framework to a client's goals, tax profile, and personal priorities, an advisor can turn a champagne problem into a champagne plan.
