I need a tax form in spain (example) i want know that hoe info the google need for tax in spain ! please give me a screen shot or a .doc file
google only needs tax ID or SIN for US publishers. you are a foreign publisher with no US activity (more than likely) therefore google doesn't need your tax info.
Yes, you have to fill that form, but as you are not from US, you just need to declare that you are not a US resident or something, and then sign the form at the end. That's it.
