Hi,
Individual who has not filed 2015-2017 Tax Returns has a carryback loss from 2016 and 2017 for 2015 gains. Could we file 2016 and 2017 tax return first and then claim the carryback NOL on 1040, or do we need to first file 2015 1040 without carryback and then file 1040X/1045 to do carryback.
All help appreciated.
Thanks,
