Well, maybe not my best idea. The LLC is not in existence yet but the partnership was formed in 2019. They are going to form an LLC. My thought was to get the LLC EIN on 3/16/20 and file the return with that EIN. Then form the LLC.

I suppose I should get an EIN for a partnership name for 2019 and file under that. Then get the LLC set up in 2020 and use the new name and EIN.

I'm not inclined to file two partnership returns in 2020 so I would probably have to use the non LLC partnership for 2020 then have a tax free exchange to the LLC on 1/1/21 nd use the LLC in 2021.

My original idea is easier and harmless but not technically correct.

Any thoughts?
