Can some stock losses be deducted from income taxes?

Yes, some stock losses can be deducted from income taxes in the United States. If you sell stocks at a loss, you can use those losses to offset capital gains from other investments. If your total net capital loss exceeds your capital gains, you can deduct up to $3,000 ($1,500 if married filing separately) from your ordinary income. Any remaining losses can be carried forward to future tax years.
