Questions people often ask
Can a long-term loss reduce short-term gains?
No. Long-term losses can only be set off against long-term gains. Short-term losses can go against either.
I made a loss but owe no tax. Should I still file?
Yes, by the due date, so the loss carries forward to reduce tax on future gains.
