Do you need to file a 1040x to report a change in the NOL carryforward from a prior year or can you just add a statement to the current year return with the change ?
I am adding an expense that was missed on the 2017 1040. The taxpayer had an NOL so it does not change the liability for 2017, only the NOL C/F to 2018. Do I have to amend the 2017 return or can I just reflect the change on the 2018 statements? I believe CA allows you to just include a statement with the current year so I am hoping the IRS also allows this. Please advise.
