When I referred to an amended return, I was asking if amending it to MFJ would then allow them to avoid the 6% excise tax. Could I do that?
I think you could probably go back to 2016. I always have to use my fingers for these things...2016 was due 4/15/17 + 3 years is 18, 19, 20. So should be open to amend until at least 4/15/20.
