Tax-loss harvesting is a tax-saving investment strategy that involves selling securities at a loss to offset gains made from other investments, reducing your overall taxable income and potentially increasing your after-tax returns.​
How Tax-Loss Harvesting Works
When you sell an investment that has gone down in value, the loss you realize can be used to offset capital gains you’ve made from other investments sold at a profit during the year. If your total capital losses exceed your capital gains for the year, you can deduct up to $3,000 from your taxable income, with any remaining losses carried forward to future years. This technique is only relevant for taxable accounts, not retirement accounts like 401(k)s or IRAs, where investment growth is tax-sheltered.​
Steps Involved in Tax-Loss Harvesting
- Identify underperforming investments in a loss position that no longer meet your goals.
- Sell these investments to realize a capital loss.
- Use these losses to offset gains made from other investment sales.
- Reinvest the proceeds into similar assets to remain invested, while adhering to IRS wash sale rules (cannot buy the same or “substantially identical” investment within 30 days before or after the sale for the loss to count).​
Benefits of Tax-Loss Harvesting
- Directly reduces your tax burden by lowering taxable gains and, in some cases, ordinary income.​
- Boosts your portfolio’s after-tax return by allowing more of your money to keep growing.​
- Losses not used in the current year can be carried forward and applied in future tax years.​
Limitations and Considerations
- Most helpful for investors in higher tax brackets.​
- Only available in taxable investment accounts.​
- Transaction costs and market risks should be considered when repurchasing replacement assets, as performance could vary and costs might offset savings.​
- Following IRS guidelines, especially the wash sale rule, is critical to ensure losses are eligible for offset.​
- Taxes alone should not drive investment decisions; portfolio goals and diversification are also vital.​
Use of Technology and Advisors
Modern digital platforms and robo-advisors can automate the process, continually scanning for opportunities to realize tax losses and reinvest in similar, but not identical, positions, making the strategy accessible to everyday investors without deep financial expertise.​
Key Takeaways
- Tax-loss harvesting can reduce your tax burden and improve portfolio returns, especially for high-income earners with taxable accounts.
- Be sure to understand the rules and work with a financial or tax advisor to maximize the benefits and avoid disallowed losses.​
- Done right, tax-loss harvesting can be a powerful year-round strategy, not just for year-end tax planning.​
If you’re evaluating this strategy for your portfolio, keep in mind its relevance depends on your account types, tax situation, and investment objectives.
