Ok thanks...but do you have filled any w8 or w9 form? Or did you give them only your paypal email?
Thanks.
If you're the US citizen and you supposed to get paid for the partnership, so yes, exactly. Actually, you should fill a W-9 on every commercial company you have an income from. I'm doing so with the IRS website (they have templates prefilled) or this w9.pdffiller.com in case the first one doesn't work or the company gave you a wrong template, which you could edit. But consider that this is a paid tool
