What Is Tax-Loss Harvesting? Benefits, Risks, and Key Rules to Know
Tra Sullivan
Learn how tax-loss harvesting works, its potential tax benefits, wash-sale rules to avoid, and key considerations for investors seeking greater tax efficiency.
Taxes can have a significant impact on long-term investment results. While investors cannot eliminate taxes entirely, they can often implement strategies that help improve after-tax outcomes. One of the most effective tax-management techniques available to taxable investors is tax-loss harvesting.
By strategically realizing investment losses, investors may be able to offset capital gains, reduce taxable income, and potentially keep more money invested for future growth.
Here's what you need to know about tax-loss harvesting and whether it may be appropriate for your financial plan.
What Is Tax-Loss Harvesting?
Tax-loss harvesting is a strategy that involves selling investments that have declined in value and using those realized losses to offset taxable gains elsewhere in a portfolio.
The process typically involves three steps:
- Identifying investments that are trading below their purchase price
- Selling those investments to realize a capital loss
- Reinvesting the proceeds into a similar investment to maintain portfolio exposure
The goal is to capture a tax benefit without significantly altering the portfolio's long-term investment strategy.
Potential Benefits of Tax-Loss Harvesting
1. Offset Capital Gains
Realized capital losses can be used to offset realized capital gains during the same tax year.
Tax rules distinguish between:
- Short-term gains and losses (investments held one year or less)
- Long-term gains and losses (investments held more than one year)
Generally, losses first offset gains of the same type before being applied to gains of the other type. For investors who have realized gains from selling stocks, mutual funds, real estate, or other investments, harvested losses may help reduce or eliminate a portion of the resulting tax liability.
2. Reduce Taxable Income
If net capital losses exceed net capital gains for the year, up to $3,000 of excess losses may be used to offset ordinary income, subject to IRS rules.
This can potentially reduce a taxpayer's overall tax liability for the year.
3. Carry Losses Forward
Any unused losses can generally be carried forward indefinitely to future tax years.
These carryforward losses may be used to offset future capital gains and can continue providing tax benefits long after the original losses were realized. Losses retain their character as short-term or long-term when carried forward.
4. Keep More Assets Invested
Tax-loss harvesting often creates a tax deferral benefit rather than permanent tax elimination. However, deferring taxes can still be valuable because assets that otherwise would have been used to pay taxes remain invested and have the opportunity to grow over time.
By reducing taxes today, investors may increase the amount of capital that remains invested, potentially enhancing after-tax wealth through compounded growth.
Important Considerations Before Harvesting Losses
While tax-loss harvesting can be beneficial, it is not appropriate in every situation.
Future Tax Rates Matter
The value of tax-loss harvesting depends in part on an investor's current and future tax situation.
Harvesting losses may provide immediate tax savings and allow more assets to remain invested. However, the long-term benefit can vary depending on future tax rates, investment performance, and when gains are ultimately realized. Because these factors are difficult to predict, tax-loss harvesting should be viewed as one component of a broader tax and investment strategy.
Opportunities May Decline Over Time
As portfolios grow and investments appreciate, opportunities to realize losses may become less frequent.
For this reason, tax-loss harvesting is often most effective during periods of market volatility or market declines, when more investments may be trading below their purchase price.
Taxes Shouldn't Drive Every Investment Decision
Investors should avoid making investment decisions solely for tax reasons.
The primary objective should remain maintaining an investment strategy that aligns with long-term financial goals, risk tolerance, and asset allocation targets. Any tax benefits should be considered secondary to sound investment management.
Understanding the Wash-Sale Rule
One of the most common mistakes investors make when harvesting losses is triggering a wash sale.
The IRS wash-sale rule generally applies when an investor sells an investment at a loss and purchases the same or a substantially identical investment within 30 days before or after the sale.
When a wash sale occurs:
- The loss is disallowed for current tax purposes.
- The disallowed loss is added to the cost basis of the replacement investment.
- The immediate tax benefit is deferred until the replacement investment is sold in a taxable transaction.
The 61-Day Wash-Sale Window
The wash-sale period covers:
- 30 days before the sale
- The day of the sale
- 30 days after the sale
As a result, investors should consider both recent purchases and planned purchases when implementing a tax-loss harvesting strategy.
How Investors May Avoid a Wash Sale
Many investors seek to maintain market exposure after harvesting a loss. This is often accomplished by purchasing an investment that provides similar market exposure without being considered substantially identical to the investment that was sold.
Because the definition of substantially identical is not always clear, investors should carefully evaluate replacement investments before executing transactions.
Additional Considerations
Wash-sale rules can apply across multiple accounts, including taxable brokerage accounts, joint accounts, and certain retirement accounts. Investors should consider all related accounts when evaluating potential wash-sale exposure.
Because wash-sale rules can be complex, investors should consult with their tax advisor before implementing any tax-loss harvesting strategy.
Is Tax-Loss Harvesting Right for You?
Tax-loss harvesting is often considered by investors who:
- Have taxable investment accounts
- Regularly realize capital gains
- Seek to improve the tax efficiency of their investment portfolio
- Maintain a long-term investment horizon
- Want to keep more of their portfolio working toward their financial goals
However, tax-loss harvesting is not appropriate in every situation.
The potential benefits depend on a variety of factors, including an investor's current and future tax circumstances, portfolio composition, investment objectives, holding periods, and overall financial plan. Tax considerations should be evaluated alongside investment goals rather than in isolation.
A qualified tax and financial advisor can help determine whether tax-loss harvesting aligns with your specific circumstances.
The Bottom Line
Tax-loss harvesting can be a valuable strategy for improving tax efficiency within a taxable investment portfolio. By strategically realizing losses, investors may be able to reduce current taxes, offset future capital gains, and potentially keep more assets invested over time.
However, tax-loss harvesting is not a standalone solution. Its effectiveness depends on an investor's unique tax situation, investment strategy, and long-term financial objectives.
When incorporated into a comprehensive investment and financial plan, tax-loss harvesting can help support long-term wealth-building and after-tax planning goals.

Frequently Asked Questions About Tax-Loss Harvesting
1. What is tax-loss harvesting?
Tax-loss harvesting is a tax-planning strategy that involves selling investments that have declined in value to realize a capital loss. Those losses can be used to offset capital gains and, in some cases, reduce taxable income. The goal is to improve the tax efficiency of a taxable investment portfolio while maintaining an investment strategy that supports an investor's long-term financial objectives.
2. How much can tax-loss harvesting save in taxes?
The amount of tax savings depends on factors such as your tax bracket, the size of your realized gains, and the amount of losses available to harvest. Capital losses can offset capital gains dollar-for-dollar, and if losses exceed gains, up to $3,000 of excess losses may be used annually to reduce ordinary income.
3. What happens if my losses are greater than my gains?
If your capital losses exceed your capital gains, you may use up to $3,000 of net losses each year to offset ordinary income. Any remaining losses can generally be carried forward indefinitely to future tax years and used to offset future gains or income.
4. What is the wash-sale rule?
The wash-sale rule prevents investors from claiming a tax loss if they purchase the same or a substantially identical investment within 30 days before or after selling it at a loss. If a wash sale occurs, the loss is disallowed for current tax purposes and added to the cost basis of the replacement investment.
5. Can I stay invested while harvesting losses?
Yes. Many investors reinvest the proceeds from a sale into a different investment that provides similar market exposure while avoiding a wash sale. This approach can help maintain a long-term investment strategy while still capturing a potential tax benefit.
6. Is tax-loss harvesting only beneficial during market downturns?
While market volatility often creates more opportunities to harvest losses, tax-loss harvesting can be useful whenever certain investments in a portfolio are trading below their purchase price. Even in generally positive markets, some sectors, asset classes, or individual holdings may present opportunities.
7. Should every investor use tax-loss harvesting?
Not necessarily. Tax-loss harvesting is generally most beneficial for investors with taxable investment accounts. Investors holding assets primarily in tax-advantaged accounts such as IRAs or 401(k)s typically receive little or no benefit from the strategy. Because every tax situation is different, investors should consult with their financial advisor and tax professional before implementing tax-loss harvesting strategies.
Tax-loss harvesting and other tax-management strategies may not be appropriate for all investors. The potential benefits of any tax strategy depend on an individual's specific circumstances, including tax status, investment objectives, portfolio composition, and applicable tax laws. Tax benefits are not guaranteed and may be affected by future changes in tax laws, investment performance, or other factors. Investors should consult their tax advisor regarding the application of any tax-related strategy to their individual situation.
