Investors realize capital gains when they sell appreciated assets. Long-term capital gains (held over 1 year) are taxed at 15-20% depending on your bracket, plus potential 3.8% Net Investment Income Tax for high earners. For a $500,000 gain, the tax could be $100,000-120,000. Strategic planning can cut this in half.
Timing Asset Sales
Recognize gains in low-income years and losses in high-income years. If you have a $200,000 gain and $200,000 in losses, net them and owe tax on $0. Alternatively, recognize losses in high-income years (saving 37% of the loss value) and gains in lower-income years (paying only 20% on the gain).
1031 Exchanges for Real Estate
Under IRC 1031, exchange real estate properties of like-kind and defer all capital gains. Selling a $2,000,000 property with $800,000 gain typically triggers $240,000 in taxes. A 1031 exchange defers all gain indefinitely. You can continue this strategy across multiple exchanges for decades, deferring taxes until you eventually sell for cash.
Opportunity Zone Investments
Under IRC 1400Z-2, invest capital gains in Qualified Opportunity Zone funds to defer gain recognition until 2026. If you have a $500,000 capital gain, reinvest in an Opportunity Zone fund. You defer recognizing the gain, allowing you to offset it with losses or recognize it in a lower-income year.
Charitable Remainder Trusts
Fund a CRT with highly appreciated assets ($2,000,000 in stock with $1,500,000 gain). The trust sells the assets tax-free (no capital gains tax on the $1,500,000 gain). You receive income distributions for life (5-8% annually). At death, the remainder goes to charity. You deduct the charity's remainder interest (roughly $200,000-300,000), providing significant tax savings while avoiding the capital gains tax entirely.
Tax-Loss Harvesting
Systematically harvest losses throughout the year to offset gains. If you have $500,000 in gains and can harvest $500,000 in losses, you net to $0 capital gains. Then repurchase similar (not identical) securities to maintain your portfolio. This converts tax liability to zero while maintaining your investment position.
Wash Sale Rule Considerations
The wash sale rule (IRC 1091) prevents claiming losses on securities if you repurchase the same security within 30 days. However, you can repurchase similar securities (different company, same sector) immediately. Plan loss harvesting carefully to respect the 30-day rule while maintaining your portfolio positioning.
Strategic Asset Location
Place high-growth, high-turnover investments in tax-deferred accounts (401(k)s, IRAs, Roth IRAs) where gains don't trigger taxes. Place low-growth, low-turnover investments in taxable accounts. This positioning minimizes annual capital gains in taxable accounts.
Holding Period Planning
The difference between short-term and long-term capital gains rates is 17-22% (short-term is ordinary income rates, long-term is preferential rates). If you hold an asset just long enough to cross the 1-year threshold, you might save 17-22% on the entire gain. For a $1,000,000 gain, holding 3 more months to reach long-term status saves $170,000-220,000 in taxes.
Bunching and Charitable Giving
In years with large capital gains, bunch charitable contributions to maximize your deduction. A $100,000 charitable contribution deduction saves $37,000 in federal taxes (at 37% marginal rate), partially offsetting the capital gains tax.
Professional Planning
A tax advisor can model different scenarios: What if I sell now vs. next year? What if I use a 1031 exchange vs. selling outright? What if I fund a CRT? These models often reveal $50,000-200,000+ in potential tax savings through timing and strategy selection.
