W-9: Who is it should be filed under

[Davit Gharibyan]

Hello,

I have a property that is owned by LLC "A" and is managed by LLC "B". I own both entities. I have some tenants and applicants with government/non-profit assistance.

During application and once individuals become tenants, these orgs ask for W-9. 

Rents and rental application fees go to LLC "B".

When providing a W-9, should I provide it for LLC "A" or LLC "B"?

I realize that this is a CPA question, any non-professional suggestions and opinions are appreciated.
