Yes, since they changed how futures were taxed, it was only 3 years, but there was a special provision, again I think due to Covid, that permits I think 7-year carry-back. However, I'm not sure if it was futures carry-back, or maybe just NOL, as I'm a trader in stocks & stk options, but not futures. Maybe it was just "regular" business NOL that was able to go back 7 years.
Could you please forward me your accountant's information who helps you with the carry-back? Thank you so much.
