Thanks, but I don’t think that link addresses the MFS/MFJ issue. Two things did catch my interest though:
1. Carrying the ITC “back one year” ? Even looking at theForm 5695 info, I’m not sure what that means. Does it mean tax liability in 2019, as well as for 2020, would count towards the “limitation based on tax liability” ?
2. I saw that if construction commenced in 2019, I’m eligible for the maximum 30% credit even though I didn’t complete the project in 2019. That is good news indeed !
