The 1099 you receive at the end of the year will reflect this loss with all your other gains & losses for each stock. Your losses will offset any gains you have up to the amount of your loss.
If your losses exceed your gains, you can write them off up to the amount of your gains + $3,000 more.
You should know that already, unless your are new to investing. If you are, you should run from all penny & sub-penny stocks until you get a few years investing under your belt. Just my opinion. I say that with the best of intention for you as an investor.
