5 High-Tax Scenarios Where Long/Short Strategies Can Add Value

October 15th, 2025

Estimated Reading Time: 7 Minutes

For ultra-high net worth individuals, significant wealth events often come with equally significant tax consequences. Whether it’s the sale of a private business, a piece of investment real estate, or a concentrated stock position, the tax on the resulting capital gains can limit your net overall return.

While many investors are familiar with strategies like charitable gifting or installment sales to help manage this impact, fewer are aware of the significant impact a tax-aware long/short investment strategy can have in offsetting realized gains. When executed correctly, this approach can help generate targeted tax losses without sacrificing overall portfolio integrity.

Below, we explore how this type of strategy works, and how it can be applied to mitigate taxable gains across a range of complex scenarios.

Understanding Tax-Aware Long/Short Strategies

A traditional long/short strategy involves holding long positions in securities expected to rise in value, while simultaneously shorting securities expected to decline. In a tax-aware version of this approach, the portfolio is actively managed for risk and return, tax character, and timing of gains and losses.

Rather than simply optimizing for performance, the tax-aware strategy introduces a second dimension: realizing losses in a strategic, intentional way. These losses can then be used to offset gains realized in the portfolio.

This level of control and flexibility helps optimize taxable accounts after-tax returns, the true measure of investment success. It can help investors facing a large tax bill in multiple scenarios. We will explore these scenarios below.

Scenario 1: Offsetting Gains from a Concentrated Stock Position

Many UHNW individuals accumulate significant wealth in the form of concentrated stock—through equity compensation, inheritance, or the sale of a business. Selling those positions can trigger large long-term capital gains.

Rather than facing the entirety of the tax burden, investors can use a tax-aware long/short portfolio to generate realized losses during the same period. These losses come from securities you short that then increase in value. On paper these are losses while they might really cost you a smaller amount than your tax burden. Using these losses to offset gains can help you preserve more of your capital. The strategy can also be used as part of a multi-year diversification plan, supporting gradual liquidation while managing both market risk and tax drag.

Scenario 2: Managing Short-Term Capital Gains

Short-term gains, taxed at ordinary income rates, are among the least efficient forms of investment return. For those with alternative asset exposure, short-term gains can accumulate quickly and push total income into the highest federal tax brackets.

Tax-aware long/short strategies can be used to realize short-term capital losses. By intentionally capturing losses throughout the year, the strategy reduces overall taxable income, costing the investor less and improving the after-tax return on investment.

Scenario 3: Addressing Long-Term Capital Gains and Carry

Even when capital gains qualify for long-term treatment, they can still result in substantial tax liability—particularly when gains are triggered by the sale of private investments, carried interest distributions, or legacy stock positions.

In these scenarios, a tax-aware long/short strategy acts as a flexible loss engine. Losses generated within the portfolio can be applied against gains from passive investments, private equity distributions, or fund carry. Because the manager controls the realization schedule, the strategy can be tailored to match the timing and character of the gains the investor is facing in a given year.

Scenario 4: Supporting Real Estate Sales

Real estate sales, especially after years of depreciation and appreciation, often lead to gains that are difficult to defer or shelter. When 1031 exchanges are not available or not aligned with the client’s goals, a tax-aware strategy can provide an alternative method to offset those gains.

The benefit of a market-based tax-aware strategy such as long/short is its liquidity and precision. Unlike real estate, which is illiquid, securities portfolios can be adjusted dynamically to realize losses at the right time and in the right amount. Tax-aware long/short can be a tool to manage tax consequences for real estate investors looking to rebalance their portfolios or exit appreciated assets.

Scenario 5: Pre-Sale Planning for a Business Exit

Selling a private business typically results in a once-in-a-lifetime liquidity event and preceding a large capital gain. While estate planning and charitable strategies can help reduce the tax burden, they often require years of lead time.

A long/short tax-aware portfolio, can be deployed within a shorter planning window and can assist legacy plans through capital management. By positioning the strategy in advance of the transaction, investors can begin building a loss reserve to apply against the gain in the year of sale. Because losses can be harvested in a targeted and controlled way, the approach complements broader pre-sale planning efforts and enhances overall after-tax outcomes.

Important Considerations

Implementing a tax-aware strategy is not a one-size-fits-all solution. It is a complex investment strategy that requires coordination with the investor’s broader financial plan and must be tailored to the nature of the gains being offset.

It’s critical to manage wash sale rules, track holding periods, and avoid undermining long-term portfolio objectives in pursuit of short-term tax benefits. This type of strategy can be best implemented by a manager with experience navigating the nuances of both investment markets and tax code.

Conclusion

A long/short tax-aware strategy is an investment technique that can be used as a powerful tax planning tool. When used intentionally, it can reduce the impact of capital gains, smooth taxable income across years, and support long-term wealth preservation.

For high-net-worth families navigating complex income events or planning significant asset sales, this strategy can be a sophisticated and flexible way to manage tax exposure without compromising overall portfolio strategies.
