No investor wants to see losses in their portfolio. But when certain investments are underperforming, selling them at a loss can actually be a smart tax strategy.
This approach is called tax loss harvesting. It allows investors to use realized losses to offset gains, reduce taxable income, and create future tax benefits. Instead of letting a losing investment sit idle, you can use it to improve your after-tax results.
What Is Tax Loss Harvesting?
Tax loss harvesting is the process of selling investments in a taxable account that have declined in value in order to realize a capital loss.
Those losses can then be used to:
- Offset capital gains from other investments
- Reduce up to $3,000 of ordinary income each year
- Carry forward unused losses to future tax years
This strategy is especially useful for investors with realized gains, higher taxable income, or a need to rebalance their portfolio.
Tax loss harvesting does not apply to tax-deferred accounts such as IRAs or 401(k)s.
How Tax Loss Harvesting Works
Tax loss harvesting is straightforward in concept.
1. Sell Investments at a Loss
You identify securities in your taxable portfolio that are worth less than what you paid for them and sell them.
2. Use Losses to Offset Gains
The realized losses can offset taxable gains from other investments sold during the same year.
3. Reduce Ordinary Income
If your losses are greater than your gains, you can use up to $3,000 of excess losses to reduce ordinary taxable income.
4. Carry Forward Remaining Losses
Any losses above that amount can be carried forward indefinitely to offset gains or income in future years.
Example of Tax Loss Harvesting Savings
Here is a simple example of how tax loss harvesting can work.
Scenario
- Realized losses: $30,000
- Realized gains: $25,000
Tax Outcome
Your $30,000 in losses fully offsets your $25,000 in gains. That means you owe no capital gains tax on those gains for the current year.
You still have $5,000 in losses remaining.
- $3,000 can be used to offset ordinary income this year
- $2,000 carries forward to future tax years
Estimated Tax Savings
Assuming:
- Long-term capital gains tax rate: 15%
- Ordinary income tax rate: 35%
You could save:
- $3,750 by offsetting $25,000 in capital gains
- $1,050 by offsetting $3,000 in ordinary income
Total current-year estimated tax savings: $4,800
Why Tax Loss Harvesting Matters
Tax loss harvesting can do more than reduce taxes in a single year.
Lower Your Tax Bill
Using losses strategically can reduce what you owe today.
Improve Portfolio Rebalancing
It allows you to reposition your portfolio while creating tax value.
Carry Forward Future Benefits
Unused losses are not wasted. They can be used in future years.
Enhance After-Tax Returns
The more tax-efficient your portfolio is, the more of your returns you may keep.
Key Rules to Watch
Tax loss harvesting can be powerful, but there are important rules to understand.
Wash Sale Rule
You cannot claim a loss if you buy the same or a substantially identical security within 30 days before or after the sale.
Taxable Accounts Only
This strategy only works in taxable investment accounts, not retirement accounts.
Higher Brackets Benefit More
The higher your tax bracket, the more valuable the savings may be.
Final Thoughts
Tax loss harvesting can turn an uncomfortable part of investing into a practical financial advantage.
By using investment losses intentionally, you may be able to offset gains, reduce taxable income, and improve long-term tax efficiency. For investors with taxable portfolios, this can be a valuable strategy when managed carefully.
Because tax rules matter, it is wise to review your options with a financial professional before making major decisions.
