Tax-loss harvesting is a powerful and versatile strategy that high earning investors can use to meaningfully lower their tax bills each year. By purposefully selling investments that have declined in value, it is possible to use these capital losses to offset gains from other holdings. This approach not only reduces what investors owe in capital gains taxes, but can also support a disciplined, long-term investment plan and help keep a portfolio working toward its goals.
What Is Tax-Loss Harvesting?
At its core, tax-loss harvesting is the process of reviewing a taxable investment portfolio for positions that are trading below the original purchase price and selling them to realize a capital loss. Once the loss is realized, it can be used to offset realized capital gains from other investments for that tax year. The process is legal, straightforward, and highly valuable for investors with significant income or substantial taxable gains.
Mechanics of Offsetting Gains with Losses
When gains and losses are combined at tax time, the losses first offset gains of the same type; short-term losses are used to offset short-term gains, and long-term losses are applied to long-term gains. If the net result is a loss, investors may use up to $3,000 per year of that amount to reduce ordinary income. If losses exceed that threshold, the remaining amount can be carried forward for use in future tax years, providing a tax-saving opportunity that lasts for years.
Practical Example
Consider an investor who realizes $50,000 in capital gains in one year but also has $35,000 in realized capital losses by selling positions at a loss. On the tax return, the $35,000 in losses entirely offsets an equal amount of gains, so only $15,000 in gains are subject to tax. If this investor had losses that exceeded gains for the year, up to $3,000 could be used to reduce ordinary income, with the balance carried forward.
Maximum Effect for High Earners
High earning individuals may be subject to the highest capital gains tax rates as well as the net investment income tax. For these investors, every dollar of gain offset by a loss has a major positive benefit in terms of after-tax wealth. Tax-loss harvesting is a way to actively manage a portfolio’s tax burden each year and can be even more effective when implemented systematically or with the help of automated tools and direct indexing.
Potential Steps to Take
- Regularly review taxable accounts for depreciated positions that meet tax-loss harvesting criteria.
- Sell losing positions and immediately reinvest in reasonably similar, but not identical, securities to preserve the portfolio’s asset allocation.
- Be mindful of the IRS wash-sale rule, which prevents claiming a loss if the same or a substantially identical security is purchased within 30 days before or after the sale.
- Track losses across tax years and ensure unused losses are properly carried forward or used to reduce ordinary income.
Best Practices and Learnings
Experienced investors integrate tax-loss harvesting into their wealth management plans, not just as a year-end exercise but as a year-round discipline. Using this approach, investors make the most of market downturns and minimize the impact of taxes on long-term growth. For high earners, the ability to carry losses into future years adds significant flexibility and amplifies the tax mitigation benefits. Transaction costs, short-term portfolio drift, and emotional pitfalls are considerations, so working with a professional advisor can lead to more optimal outcomes.
Final Thoughts
Tax-loss harvesting can transform losses on paper into concrete tax savings, giving investors greater control over their after-tax returns. Every investor’s tax situation is unique, so it may be wise to coordinate these strategies with a financial advisor or tax professional familiar with the nuances of both the portfolio and the latest tax code.
