Tax Efficient Portfolios for High-Net-Worth Investors

---

For high-net-worth investors, investment success is measured not only by returns, but by how much of those returns are retained after taxes. A thoughtfully constructed portfolio can help reduce tax drag, improve after-tax performance, and support long-term wealth preservation.

Tax-efficient portfolio construction integrates investment management and tax planning to help investors keep more of what they earn.

Different investments generate different types of taxable income. Placing assets in the appropriate account type can improve overall tax efficiency.

For example:

• Tax-efficient equity investments may be well suited for taxable accounts.
• Bonds and income-producing assets may be better held in tax-deferred retirement accounts.
• Growth-oriented investments can often benefit from Roth accounts, where future gains may be tax-free.

The goal is to place investments where they can generate the greatest after-tax benefit.

High-net-worth investors often accumulate significant unrealized gains over time. Selling appreciated assets without a plan can create substantial tax liabilities.

Strategies may include:

• Tax-loss harvesting
• Gradual realization of gains
• Charitable gifting of appreciated securities
• Coordinating sales with lower-income years

Proper planning can help reduce the tax impact of portfolio changes.

Certain investments are inherently more tax-efficient than others.

Examples include:

• Broad-market index funds
• Tax-managed mutual funds
• Exchange-traded funds (ETFs)
• Municipal bonds for taxable accounts

These investments may help reduce annual taxable distributions and improve after-tax returns.

Many high-net-worth investors hold significant positions in a single stock due to business ownership, stock compensation, or inheritance.

While concentrated positions can create wealth, they also increase risk and may complicate tax planning.

A structured diversification strategy can help manage both investment risk and tax consequences.

Investment decisions should not be made in isolation. Changes in income, retirement plans, charitable goals, business transactions, and estate planning strategies can all affect portfolio construction decisions.

By coordinating investment management with tax planning, investors can often identify opportunities that may otherwise be overlooked.

Tax-efficient investing is not simply about minimizing taxes this year. The objective is to maximize after-tax wealth over a lifetime.

This may involve balancing current tax savings with future opportunities, preserving flexibility, and aligning investment decisions with long-term financial goals.

We help high-net-worth investors integrate tax planning and investment management to create strategies designed to preserve wealth and improve after-tax outcomes.
