The Tax-Aware Investing Playbook
Taxes: The biggest manageable cost in investing
Key Points
What it is
Tax-aware investing integrates tax considerations into every investment decision, not just at year-end.
Why it matters
Managing them with discipline can meaningfully improve long-term after-tax outcomes.
Where it's going
Advances in technology and portfolio design are making system-driven tax management more accessible.
What Matters Most is What Investors Keep
For many high-net-worth investors, taxes represent the single largest cost associated with their portfolios. Yet taxable portfolios are too often managed with taxes as an afterthought, addressed at year-end rather than a core component of the investment process.
That approach overlooks an important reality: the tax consequences of investment decisions are often visible in advance. When taxes are considered only at certain points in the investment process, opportunities to improve after-tax outcomes may be missed.
The discipline of tax economics — understanding how investment decisions interact with tax consequences — can therefore play a meaningful role in long-term wealth accumulation.
Investment results are frequently judged by pre-tax returns. But for most high-net-worth investors, the more meaningful measure is what remains after taxes.For many high-net-worth investors, taxes represent the single largest cost associated with their portfolios.

Exhibit 1: Impact on Portfolio Value: Deferred vs. Realized Gains
“For high‑net‑worth investors, disciplined tax‑loss harvesting may help turn tax savings into added flexibility for future expenses (e.g., Funding 4‑year college)."
The Shift From Reactive to Proactive Tax Management
Historically, tax management often meant manually harvesting losses in December to offset gains. Today, several developments are enabling more continuous and systematic approaches:
- Lower trading costs and commissions
- Advances in automation and technology
- The introduction of fractional shares
- Greater access to separately managed accounts
Together, these innovations have lowered the barriers to tax-aware portfolio management, making strategies once limited to very large portfolios accessible to a broader range of investors.
At the same time, competition for assets has intensified. Clients increasingly expect personalized portfolios and more holistic wealth management.
Avoiding these pitfalls is an important first step. But the larger opportunity lies in embedding tax awareness directly into portfolio management.
Where Tax-Aware Investing Creates Value
Tax-aware investing is a collection of practices that work together over time.
The following strategies underpin the discipline of tax economics:
Optimizing asset location
Placing investments in the most tax-appropriate accounts can improve efficiency —for example, holding tax-inefficient assets in tax-advantaged accounts while reserving taxable accounts for more tax-efficient investments.
Deferring gains
Deferring the realization of gains allows capital that would otherwise be paid in taxes to remain invested and continue compounding.
Managing concentrated positions
Gradually diversifying concentrated holdings can help reduce risk while managing the associated tax burden. For example, an executive with a large employer stock position may gradually diversify while harvesting losses elsewhere in the portfolio to help offset realized gains.
Planning for major liquidity events
Tax-aware strategies can also support planning around large future gains. Business owners anticipating the sale of a company, for example, may begin implementing tax-aware portfolios years in advance to accumulate losses that can offset future gains.
Systematic loss harvesting
Even in rising markets, individual securities often experience declines. Harvesting those losses can offset gains elsewhere in a portfolio and improve after-tax outcomes over time.
Exhibit 2:The Strategic Role of Tax Loss Harvesting
In the past, managing these dynamics systematically has been difficult in practice. A single taxable portfolio may contain hundreds of securities and thousands of individual tax lots, with tax opportunities appearing and disappearing quickly as markets move. Today, advances in technology are making it possible to manage these dynamics far more systematically.
The Rise of Personalized Portfolios
One example is direct indexing, an approach that allows investors to own the individual securities that make up an index rather than a pooled investment vehicle. Because investors directly own each security, portfolios can be managed at the tax-lot level.
This structure enables several potential advantages:
- Harvesting losses across individual securities
- Deferring gains more effectively
- Customizing portfolios to match investor preferences
- Transitioning portfolios more tax-efficiently
Direct ownership of securities can also provide greater flexibility than pooled vehicles like mutual funds or exchange-traded funds, which generally cannot distribute losses to investors. It can also make it easier to coordinate tax management across multiple accounts and investment strategies.
More broadly, technology is enabling a new generation of personalized portfolios. With direct indexing, portfolios of all sizes can now be tailored to an individual investor’s tax circumstances, investment goals and constraints.

POTENTIAL CONSIDERATIONS FOR DIRECT INDEXING ACCOUNTS
The ability to generate losses may be lower than expected, especially in markets that are rising significantly. Furthermore, the continuing benefits may not be fully realized in flat or falling markets because reinvested tax savings could potentially be low or negative.
