2. What is the wash sale rule?
Question: I sold stock earlier this year for a large taxable gain. I have another stock that’s not performing well right now, so I want to sell it at a loss to help offset the capital gain. Can I then immediately buy back the stock I sell at a loss?
3. How do wash sales apply between spouses?
Question: I sold stock from my taxable account this year at a loss. My spouse purchased stock in the same company the next day. Will the wash sale rule prevent me from deducting the capital loss from my stock sale?
Joy Taylor: Yes. The wash sale rule is a sneaky rule that can easily catch people by surprise. For example, selling a mutual fund at a loss 30 days after the date a dividend is reinvested can lead to a wash sale. Also, buying stock in an IRA after selling the same stock at a loss in your taxable investment account results in a wash sale. You also have a wash sale if you sell securities, and your spouse or a corporation that you control buys substantially identical securities within the 60-day period.
4. What if I sell crypto at a loss?
Question: I own Bitcoin and I sold some at a loss earlier this year. About a week later, I bought some more Bitcoin. Does the wash sale rule prevent me from deducting the capital loss on the sale?
Joy Taylor: No. The wash sale rule doesn’t apply to taxpayers who sell cryptocurrency at a loss. The definition of securities for the purposes of the wash sale rule doesn’t include crypto. So, for example, if you own crypto that sharply falls in value, you can sell it, recognize a capital loss, and buy the same digital currency the same day or soon after.
5. How much capital losses can I deduct?
Question: How much capital loss can I deduct on my federal income tax return?
Joy Taylor: Your capital losses can offset your capital gains (which is why tax-loss harvesting is a popular strategy), plus up to $3,000 of other income ($1,500 if you are married and filing a separate return from your spouse). Excess losses are carried over to the next year and can help reduce future capital gains. For individuals, capital losses can be carried over indefinitely until they are used up.
For example, say you have $25,000 of capital gains and $40,000 of capital losses in 2025. You can use $25,000 of your capital loss to wipe out your capital gain. You can then deduct $3,000 of excess capital loss on your 2025 Form 1040 against your wages or other ordinary income and carry forward $12,000 of losses to the next year. You would use the capital loss carryforward worksheet in the instructions for Schedule D of the 1040 to figure the amount of capital loss that you can carry forward to 2026.
