Many thanks VolvoGirl. But I also read short-term loss is supposed to be (can be) used to offset short-term gain first (at a higher tax rate) before used to offset long-term gain and then ordinary income (dividend). Box 2a of 1099-DIV reports long-term gain. So the short-term loss will be used to offset long-term gain? Seems like short-term loss can be used to offset short-term gain only if both are reported on 1099-B? Many thanks.
