Capital Gains Budgets for Tax Efficiency: Managing After-Tax Investment Returns with Intention 

August 21, 2025

When it comes to investing¹, success is not measured solely by gross returns. For high-net-worth individuals and families, particularly those with taxable accounts such as individual, joint, or trust portfolios, the emphasis should be on after-tax returns. Without proper tax planning, realized capital gains can quietly diminish long-term wealth. 

One key method is setting a capital gains budget—a proactive framework designed to manage realized gains, reduce tax drag, and enhance long-term financial outcomes. 

Understanding Capital Gains and Their Implications 

Capital gains arise when an asset is sold for more than its purchase price. While this may be a favorable outcome from an investment¹ perspective, it also results in a tax obligation. 

In taxable brokerage accounts—such as individual, joint, or trust accounts—investors may incur annual taxes not only on dividends and interest, but also on gains realized from the sale of appreciated assets. Over time, these taxes can materially impact net returns. 

To illustrate the importance of managing gains with intention, consider the perspective of a corporate executive who emphasized that after-tax returns are the only meaningful measure of success. Since that time, the company in question significantly outperformed the S&P 500—a reflection, perhaps, of disciplined financial stewardship and tax-conscious decision-making. 

Introducing the Capital Gains Budget 

A capital gains budget establishes a target threshold for realized gains within a given tax year. This target serves as a planning tool that aligns portfolio management decisions with broader financial and tax objectives. 

Each January, we establish a preliminary gains target based on investment strategy¹ and anticipated liquidity needs. This baseline allows us to: 

• Plan for portfolio adjustments proactively 

• Harvest gains or losses strategically 

• Minimize the likelihood of unexpected tax liabilities 

If a client has a specific tax plan—such as one focused on income thresholds or Medicare premium brackets—we adjust the default budget to reflect those unique considerations. 

A Disciplined and Dynamic Process 

Throughout the year, every investment decision—whether related to asset allocation, liquidity, or rebalancing—is evaluated in the context of the client’s capital gains budget. Our investment¹ team regularly reviews this metric to maintain alignment with tax objectives. 

This process strikes a balance between seizing market opportunities and remaining tax-efficient. The capital gains budget serves as a strategic constraint, guiding decisions without being rigid. Should realized gains begin to approach or exceed the intended budget, we initiate a discussion with the client to realign expectations and strategy. 

Assessing Outcomes 

Our data indicates that this approach is effective. According to the Investment Company Institute, the average U.S. mutual fund has experienced approximately 1.5% in annual tax drag due to capital gains. In contrast, client portfolios at First Western Trust have experienced an average tax cost of approximately 0.7%—a significant reduction in tax impact, translating to approximately $8,000 in annual savings on a $1 million portfolio. 

Although outcomes vary depending on withdrawal rates and investment tenure, intentional budgeting has generally reduced tax costs—even in portfolios with routine cash outflows. 

Industry Practices and Our Distinct Approach 

Many investment¹ managers focus primarily on pre-tax returns. Traditional mutual funds often distribute gains based on fund flows or turnover, with little regard for the tax consequences to individual investors. 

Our firm takes a different approach. We focus on personalized, tax-integrated investment management¹ that considers the unique financial landscape of each client. This approach, while less common, can be materially beneficial to long-term outcomes. 

Factors Influencing Annual Capital Gains 

While our strategic capital gains budgeting process forms the foundation of tax management, actual realized gains are influenced by several factors: 

1. Cash Withdrawals – Generating liquidity through sales can result in taxable gains. 

2. Holding Periods – Longer holding periods often lead to larger unrealized gains. 

3. Investment Strategy Adjustments – Changes to portfolio strategy, especially in response to evolving market conditions, may trigger gains. 

4. Custom Tax Planning – Tailored strategies may aim to achieve specific tax outcomes based on detailed income and asset information. 

5. Asset Allocation Shifts – Modifications in risk exposure (e.g., reducing equity holdings) may require realization of gains. 

Presently, our capital gains budgets are informed by factors such as expected cash needs and investment outlook, unless a customized tax plan is provided. 

Emphasizing After-Tax Efficiency 

Capital gains remain an efficient mechanism for accessing funds. Investors receive their original investment amount tax-free, and gains are generally taxed at preferential rates relative to ordinary income. In our experience, accessing liquidity through capital gains is typically more favorable than withdrawing from pre-tax accounts. 

By embedding tax-conscious decision-making into investment management¹, we aim to deliver outcomes that are not only aligned with market performance, but also with clients’ long-term wealth preservation goals.
