Do I Have to Report Stock Market Losses?
Thus, add a long-term stock loss to other long-term capital losses and subtract them from the total amount of long-term gains for the year to figure long-term gain or loss. Subtract your total short-term capital losses from short-term capital gains to find net short-term gain or loss.
How are stock market losses and gains taxed?
Keeping accurate records of short- and long term stock market losses and gains is essential because the tax consequences are different. Long-term gains are taxed at a maximum rate of 15 percent. Short-term gains are taxed at ordinary income tax rates, which were as much as 35 percent as of 2012. Suppose you have a stock market loss of $2,000.
