Hi Renee - this is a really helpful explanation, thank you!
One follow-up: The main distinction you make between banks who use Form 1099-INT and others that use Form 1099-MISC really boils down to passive vs. non-passive income and making sure the legal name reported matches the EIN.
However, Form 1099-MISC can also be required to report passive income, in my case Schedule E Rental Income and Royalties. Furthermore, under the reasoning that you've used, it seems to me that it would perfectly fine for me to use the disregarded LLC's EIN on Form W-9, so long as the legal name given on Line 1 matches the EIN, just as it usually does when banks also use Form W-9 to report interest income?
