Specifically, I bought 50 units of Stock ABC on 3/1/2021 and bought another 30 units on 11/1/2021, all are currently at an unrealized loss. So I will not be able to use these losses against my LT gains when I file my 2021 taxes, even if I realized losses for these 50 initial units on 3/2/2022 (which is prior to my 2021 filing)? In other word, losses will have to be used either on the tax year they were realized or carry forward years?
Is there a duration for how long the losses can be carryover for? And do the losses accumulate, each year in the years where I have losses exceeding the allowable offset amount per year?
