Is there any body of law that would require banks to obtain tax id numbers on authorized signers of business accounts? I'm quite confident that CIP does not require it.

I'm also fairly confident that we aren't required to get it for IRS reporting purposes, but our system is flagging any authorized signers without TINs for back-up withholding. There isn't anything to back-up withhold, since they aren't actually owners on any accounts, but it is causing an operational issue.

I think I'm safe to say that this is a flaw in the system, and that we have not violated any requirement, but I'm hoping someone can confirm my thinking.

Gracias!

That's my understanding as well.

Can you put the Corporations Tax ID number in to stop the BW?

Just a thought

Sounds like an internal control as I agree with you, it isn't a requirement.
