What are the key tax-efficient investing strategies for private wealth clients?

Tax-efficient investing is one of the highest-value areas in private wealth management because taxes can erode 100-200 basis points of annual return for high-net-worth clients. Here are the core strategies:

1. Asset Location (Tax-Aware Placement)

Place tax-inefficient assets in tax-deferred accounts and tax-efficient assets in taxable accounts:

2. Tax-Loss Harvesting

Sell positions at a loss to offset realized gains, then reinvest in similar (but not "substantially identical") securities to maintain market exposure.

Example: Beacon Wealth sells $200K of a broad market ETF with a $30K unrealized loss, then immediately buys a different broad market ETF. The $30K loss offsets gains elsewhere, saving the client up to $30K × 37% = $11,100 in taxes (at the top ordinary rate, or $30K × 20% = $6,000 at the long-term capital gains rate).

3. Holding Period Management

Ensure positions are held longer than one year to qualify for long-term capital gains rates (currently 20% + 3.8% NIIT vs. 37% ordinary income rate in the US).

4. Tax-Lot Selection

When selling partial positions, choose specific lots with the highest cost basis to minimize realized gains (specific identification method vs. FIFO).

5. Charitable Giving of Appreciated Securities

Donating appreciated stock to charity avoids capital gains tax entirely and provides a deduction at fair market value. A $100K stock with $20K cost basis donated to charity saves the client both the capital gains tax on $80K gain and provides an income tax deduction.

Key Exam Tip: CFA Level III loves testing asset location decisions and the after-tax return calculation: R_after-tax = R_pretax × (1 - tax rate). But remember this simplification ignores the compounding benefit of tax deferral.
