Capital Loss Carryover: How Losses Offset a Big Gain

The order losses are used
- Short-term losses offset short-term gains, and long-term losses offset long-term gains.
- Any net loss in one group offsets net gain in the other.
- A remaining net loss offsets up to $3,000 of ordinary income.
- Anything left carries forward, keeping its short-term or long-term character. The IRS worksheet for this is in the Schedule D instructions.
Why a carryover matters before a big sale
If you have a large carryover from past stock or business losses, a sale with a large gain is the place to use it: the carryover offsets the gain dollar for dollar. That can make a lump-sum sale cheaper than expected, or change how much it is worth spreading the gain over years. Run the numbers both ways with the capital gains tax calculator.

Losses that are not capital losses
- Suspended passive losses from rentals follow their own release rules on a sale. See suspended passive losses.
- Net operating losses (from a business) are separate. For individuals, losses arising after 2020 carry forward indefinitely but generally offset only 80% of taxable income in a year.
- Section 1231 losses on business property can be ordinary losses, which is usually better than a capital loss.
Traps
- Death: unused capital loss carryovers can be used on the final joint return but do not pass to heirs or the estate.
- Wash sales: a loss on stock or securities is disallowed if you buy substantially identical securities within 30 days before or after.
- Related parties: a loss on a sale to a close relative or controlled entity is generally not allowed.
- States: most follow the federal rules, but not all; Pennsylvania, for one, does not allow capital loss carryovers.
Common questions
How much capital loss can I deduct per year?
Losses offset all of your capital gains, plus up to $3,000 of other income ($1,500 if married filing separately). The rest carries forward.
Do capital loss carryovers expire?
Not for individuals during their lifetime. They end at death after the final return.
Can a capital loss carryover offset gain from selling a business?
Yes. It offsets capital gain from any source, including the sale of a business, real estate or land.
