Can I use a 2017 new home energy credit (that I was not aware of that year) on my 2020 return or do I need to file an amended 2017 return?
NOTE: this for a property owned by an LLC which gives me a K1 for my personal return.
If I have to file an amended 2017 return then do I need to amend the 2018 and 2019 returns?
Credits must be claimed in the year the expense occurs. That would mean amending both your 2017 returns.
Also, if a multi-member LLC owns a home, I'm not sure you are eligible for the energy efficient improvement questions for your personal home. You would have to double-check the rules. If the LLC is a homebuilder and built an efficient home, there are different credits that might be available.
First - I appreciate your quick reply.
Per this blog I think we qualify since these were newly built specifically for us:
My question was the 2017 vs 2020 issue and it looks like 2017 is the answer.
