Filling out w9 as a LLC

Hi All,

I havent had to to this in a while so I forgot what is needed. I have a single member LLC in CA with an EIN Number. Do i use my personal name and SSN or Business LLC and EIN


I used the llc name and ein number. But you still can use your personal name and ss. I don’t think the irs cares as they have both names and numbers available.

Ok thats what I thought, i fill one of these out every few months and always get thrown off by the “disregarded entity”
