We show how combining charitable remainder unitrusts (CRUTs) with tax-aware strategies can help investors diversify low-basis stock and enhance after-tax wealth accumulation. Our findings suggest that investors and their advisors should integrate philanthropy and investment management to optimize wealth preservation and charitable impact.

Variable prepaid forward (VPF) contracts have been developed as a solution to hedging the risk of concentrated low-basis stock. Using options pricing theory, we develop a VPF pricing model that helps understand the VPF prepayment amount and the cash flows and tax liabilities upon VPF rolls.

We use historical strategy simulations to evaluate the advantages of donating appreciated stock in the context of tax-aware long-short factor strategies. We find long-short strategies exhibit several advantages over long-only investments.

We illustrate how combining VPFs (variable prepaid forwards) with tax-aware strategies can help diversify low-basis stock and thereby improve after-tax wealth accumulation. Long-run after-tax wealth outcomes are significantly better when a VPF is combined with tax-aware long-short factor strategies rather than with other alternatives, such as a direct-indexing strategy or a market index fund.

We explore the mechanism for how tax-aware long-short factor strategies, within their first three years since inception, can realize cumulative net capital losses exceeding 100% of initially invested capital, all while generating a significant pre-tax alpha – a result shown in previous research. Surprisingly, we find in these strategies that net capital losses arise not from an increased realization of capital losses but rather from the deferral of capital gains, especially short-term gains on long positions.

On average, net losses realized by direct indexing loss-harvesting strategies taper off within the first few years after their inception, and these strategies also exhibit a high dispersion of net loss outcomes. We show that long-short strategies motivated by factor investing can significantly outperform direct indexing strategies from both a pre-tax and tax perspective.

Entrepreneurs and executives holding much of their wealth in a highly appreciated single stock face either the high risk of idiosyncratic volatility and potentially catastrophic losses, or selling stock and facing an immediate, punitive tax burden. This paper evaluates this choice and explains how it relates to classic betting strategies and economic theory, finding tax-efficient techniques might strike the balance between the urgency to diversify concentrated risk and aversion to taxes.

As a result of recent Treasury regulations, investors in investment partnerships, such as hedge funds, might end up recognizing capital gains when they contribute their partnership interests to a charity. We explain how such taxable gains upon charitable contributions arise and quantify how punitive they might be.

An investor holding a direct indexing portfolio can obtain tax benefits by harvesting losses on individual stock positions. We show that investors with allocations to hedge funds and derivatives are the most likely category of investors to have systematic short-term capital gains in their portfolios and, therefore, benefit the most from losses harvested by direct-indexing strategies. We show how tax benefits are affected by equalizing the tax rate applicable to long-term and short-term capital gains.

We explain how hedge fund investors might be affected by a limitation on excess business losses codified in recent tax legislation. In order to allocate business losses a hedge fund now must be a trader fund. After explaining the relationship between hedge fund losses and business losses, we illustrate with simple examples how the new provisions may affect hedge fund investors.

Preservation and transfer of wealth to future generations is one of the central financial goals for most high-net-worth families. We show that a family that invests with income and estate tax efficiency in mind can achieve substantially higher wealth levels than a family oblivious to taxes.

We describe a hypothetical Tax-Aware Defensive Equity Long-Short strategy, including its construction and pre-tax and after-tax performance. The strategy closely replicates the pre-tax performance of a similar hypothetical tax-agnostic strategy and has the potential to achieve a meaningful tax benefit for a taxable investor.

For a taxable investor with a highly appreciated equity portfolio, replacing the portfolio manager is likely to trigger substantial tax liabilities. We find that a tax-aware relaxed-constraint post-transition strategy significantly outperforms a traditional tax-agnostic long-only strategy in its ability to preserve and grow the investors after-tax wealth over the long term.

Despite its unavoidable deficiency caused by current regulations, we believe that lot layering aligns tax and economics more closely than any of the “aggregation” methods presently used by most hedge funds.

We discuss certain accounting principles relevant for investors in tax-aware funds structured as limited partnerships. We present a simple stylized model that illustrates that under such accounting principles new investors do not materially suffer from unrealized gains accumulated in a tax-aware fund.

Risks of Tax Aware Strategies
This list is not exhaustive; there are numerous advantages and risks associated with our Tax Aware Strategies that are not fully discussed here.
Underperformance of pretax returns: tax-aware strategies are investment strategies with the associated risk of pretax returns meaningfully underperforming expectations.
Adverse variation in tax benefits: deductible losses and expenses allocated by the strategy may be less than expected.
Lower marginal tax rates: the value of losses and expenses depends on an individual investor’s marginal tax rate, which may be lower than expected for reasons including low Adjusted Gross Income (AGI) due to unexpected losses and the Alternative Minimum Tax (AMT).
Inefficient use of allocated losses and expenses: the tax benefit of the strategy may be lower than expected if an investor cannot use the full value of losses and expenses allocated by the strategy to offset gains and income of the same character from other sources. This may occur for a variety of reasons including variation in gains and income realized by other investments, at-risk rules, limitation on excess business losses, or insufficient outside cost basis in the partnership.
Adverse changes in tax law or IRS challenge: the potential tax benefit of the strategy may be lessened or eliminated prospectively by changes in tax law or retrospectively by an IRS challenge under current law if conceded or upheld by a court. In the case of an IRS challenge, penalties may apply.
