What is a capital loss carryover?
A capital loss carryover allows U.S. taxpayers to use unused capital losses from one tax year to offset future capital gains or ordinary income. If your total capital losses exceed your capital gains in a given year, you can apply up to $3,000 ($1,500 if married filing separately) against ordinary income. The remaining unused losses are then “carried over” to the next year until they’re fully used.
Key Takeaways
- A capital loss carryover lets you apply unused capital losses to future years.
- You can use up to $3,000 per year against ordinary income.
- Carryovers continue until fully used—no expiration.
- Proper tracking and filing on Schedule D are essential.
- Especially valuable for U.S. expats with global investments.
Understanding Capital Loss Carryovers
What Is a Capital Loss?
A capital loss occurs when you sell a capital asset—such as stocks, bonds, or property—for less than its purchase price. These losses can offset capital gains, helping lower your taxable income.
If your losses exceed your gains in one tax year, the IRS allows you to carry the remaining loss forward into future years. This process ensures you don’t lose the tax benefit of those losses just because you had more losses than gains in a single year.
How the Carryover Process Works
- Calculate Your Capital Gains and Losses
Add up your total capital gains and total capital losses for the year. Separate them into short-term (held for one year or less) and long-term (held for more than one year) categories. - Net the Gains and Losses
- If your losses exceed your gains, you can use up to $3,000 of that net loss to reduce ordinary income.
- Any remaining loss becomes a carryover to the next year.
- Apply the Carryover in Future Years
In subsequent years, you first apply the carried-over losses against any capital gains. If losses still remain, you can again use up to $3,000 per year against ordinary income until the loss is fully used. - Report on the Correct IRS Forms
Capital gains and losses—including carryovers—are reported on Schedule D (Form 1040) and Form 8949, which provide detailed calculations for each asset sold.
Example: How Capital Loss Carryover Works
Scenario:
- You sell investments in 2024 and realize a $10,000 capital loss.
- You have no capital gains for the year.
Step 1: Deduct $3,000 from your ordinary income for 2024.
Step 2: Carry over the remaining $7,000 to 2025.
Step 3: In 2025, you earn $4,000 in capital gains.
- Apply $4,000 of the carryover to offset those gains.
- The remaining $3,000 can again reduce ordinary income in 2025.
At the end of 2025, your carryover balance is zero.
Why Capital Loss Carryovers Matter
Capital loss carryovers help taxpayers smooth out investment volatility and reduce tax liabilities over multiple years. Instead of losing the tax benefit of a large loss in one year, you preserve it for future use.
For U.S. expats, this can be particularly valuable—especially if you have investment income abroad or capital gains from selling foreign property.
Common Mistakes When Handling Carryovers
- Forgetting to Track Carryovers
Many taxpayers fail to include carryovers from the previous year when preparing their next return. The IRS requires you to keep accurate records of unused losses. - Incorrectly Applying Short-Term and Long-Term Losses
Short-term losses must first offset short-term gains, and long-term losses must offset long-term gains. Only after netting within each category can you combine them. - Failing to File Schedule D Properly
Carryovers appear in Part III of Schedule D, and failing to report them correctly can lead to errors or lost deductions.
How to Access Prior-Year Carryovers
If you use tax software, your carryover amounts are automatically transferred each year. If you change tax preparers or software, you’ll need to manually input your carryover data from the Capital Loss Carryover Worksheet in your previous year’s return.
You can find this worksheet in the Schedule D Instructions on the IRS website.
