If the Bank has an expired W8 form on file associated with an interest bearing account, we need to begin backup withholding as well as begin interest reporting. If the individual that executed the W8-BEN has no SSN or ITIN, does the Bank begin interest reporting on Form 1042S?

Many of the question that you have asked can be solved by simply reading the instructions to the forms that you have mentioned.

Spoon feeding anons that want us to do all the work gets really old after awhile.
