They are taking 30% withholding tax from me. I'm Canadian and we have a treaty that says we should not have tax taken. What do I use to meet 0% withholding tax under Canada/Us treaty? Do I have to get a TIN? I think that may be the problem, I didn't put in a TIN in the Tax Interview. Should I resubmit the Tax Interview with a TIN? Will that mess anything up by doing so? How do I go about getting a refund for the tax taken? After resubmitting when will it go into affect? Thanks.
