Tax loss harvesting is a tax-saving strategy that involves selling investments at a loss to offset capital gains and, in some cases, taxable income. This practice can help investors lower their overall tax burden while maintaining their desired asset allocation.
How does this work?
- Sell Underperforming Assets: Identify securities in your portfolio that have declined in value.
- Offset Gains: Use the realized losses to offset realized capital gains from other investments.
- Reduce Taxable Income: If losses exceed gains, up to $3,000 ($1,500 if married filing separately) can be used to reduce taxable income. Excess losses can be carried forward to future tax years.

Tax loss harvesting can be beneficial, but it’s important to avoid triggering a wash sale, as it could negate the tax benefits. A wash sale happens when you sell an investment at a loss to claim a tax benefit, but then buy the same, or very similar, investment within 30 days of the sale. If the IRS determines a wash sale has occurred, the tax loss would be disallowed, and the disallowed loss is added to the cost basis of the new purchase.
Strategies to Avoid Wash Sales
- Wait 31 days before repurchasing to avoid the loss being disallowed.
- Buy a similar (but not identical) investment within the same sector or asset class.
- Suspend automatic dividend or capital gains reinvestments that could trigger a wash sale.
- Consult with a financial advisor for personalized guidance to ensure that these strategies align with your specific circumstances and comply with IRS regulations.
Tax loss harvesting can reduce taxable income and improve long-term portfolio performance, but it’s important to understand and adhere to the wash sale rules is critical to maintaining the benefits of this strategy. By leveraging these strategies and staying compliant with IRS regulations, you can take full advantage of the tax benefits while positioning your portfolio for future growth.
