The Eight Strategies

1. Harvest gains in the 0% LTCG bracket. A married couple with taxable income below roughly $96,700 (2025) pays 0% federal tax on long-term capital gains. Retirees in low-income years (between retirement and Social Security claiming, especially) can deliberately realize gains to upgrade basis at zero federal cost.

2. Tax-loss harvesting. Selling positions at a loss to offset realized gains is a year-round discipline, not just a December activity. Up to $3,000/year of net loss can also offset ordinary income; excess losses carry forward indefinitely.

3. Asset location. Hold tax-inefficient investments (high-turnover funds, taxable bond funds, REITs) in tax-deferred accounts where their distributions don't trigger annual tax. Hold tax-efficient broad equity index funds in taxable accounts where their low turnover and qualified dividend treatment work in your favor.

4. Donate appreciated securities to charity. If you give to charity anyway, donating appreciated stock or mutual fund shares (held more than one year) lets you skip the capital gain entirely while still claiming a charitable deduction at the full fair market value. A donor-advised fund makes this scalable.

5. Qualified Charitable Distributions (QCDs). Available after age 70½. Not strictly a capital gains strategy, but reduces the ordinary income that stacks gains into higher brackets. Direct IRA-to-charity transfers up to the annual limit don't count toward AGI.

6. Charitable Remainder Trust (CRT). For very large concentrated positions (e.g., a founder's stock at exit, decades of compounded employer stock), a CRT can sell the position tax-free inside the trust, provide lifetime income to the donor, and pass the remainder to charity. Material legal and administrative complexity, but the tax math can be transformative for the right situation.

7. Step-up in basis at death. Holding highly appreciated assets until death allows the heir to inherit at fair market value, eliminating the embedded gain entirely. For elderly investors with appreciated positions and adequate other income, this can be the optimal “sell never” strategy.

8. Spread realizations across multiple years. A $200,000 gain realized in one year stacks into higher brackets and triggers IRMAA. The same $200,000 spread across 4 years of $50,000 realizations may stay in lower brackets entirely. Patience is a tax strategy.

Real Scenario: A Concentrated Position Unwind

A retiree at 64 has a $400K position in a single stock with $300K of embedded long-term gain. She wants to diversify but doesn't want to pay all the capital gains tax in one year.

Reactive approach: Sell the entire $400K position in one year. Realize $300K of long-term gain. Tax (15% federal on most of it, plus state) runs ~$50K, plus triggering IRMAA tier increases on her Medicare premiums.

Structured approach:

• Donate $50K of appreciated shares to her donor-advised fund (no tax on the gain, full deduction at FMV).
• Sell $80K/year for 4 years, keeping each year's realized gain inside the 15% bracket and well under IRMAA thresholds.
• Harvest losses elsewhere in the portfolio to offset some of each year's realized gain.

Total tax across the structured plan: ~$28K instead of $50K. Plus avoiding IRMAA tier increases. Net savings: roughly $25K–$35K plus significant non-financial value (no single bad-tax-year shock).

The Combination Effect

The eight strategies are most powerful in combination, not isolation. The 0% LTCG bracket plus tax-loss harvesting plus asset location plus donating appreciated securities plus QCDs (for retirees over 70½) together can drive long-term effective capital gains rates well below the headline brackets.

Common Mistakes

• Donating cash to charity while sitting on highly appreciated stock that could be donated tax-free.
• Failing to use the 0% long-term capital gains bracket in low-income retirement years.
• Selling for cash needs without harvesting available losses elsewhere in the portfolio.
• Realizing all of a concentrated position in one year instead of spreading across multiple low-bracket years.
• Ignoring asset location and treating each account as if it had the same tax treatment.

The Bottom Line

Capital gains tax is one of the most controllable taxes for most retirees. The eight strategies aren't exotic; they're standard tools that compound when used in combination.

The retirees who pay the lowest effective capital gains rates are not the ones with the best stock picks. They're the ones who treated capital gain realization as a multi-year design problem rather than a single-year transaction.
