Hi Please help, today I was asked from AdSense to add my Tax Info... I don't have USA activities, or I thing I don't. The only thing I have on USA is my web hosting. My sites are .com .. is that USA activities? Because I host my site on a USA server? I hope someone knows.
there are some good blogs on this, sorry i don't have any links to these, but some good info on DP use the search i was in the same boat, i think if your renting a dedicated server it is different, if your using shared hosting then its ok you can tick no usa activities
if you physically dont reside in USA or dont have an office, equipments, or employees in the USA, then you dont have any US activities. half the world uses US hostings and .com sites, that doesn't make it US activity
If it was an email that told you to add your tax information, then it was probably a pishing scam to steal your information. Only trust it if the notice was given to you after you logged into your adsense account.
Don't click on a link in the email, just log into your Adsense account like you usually do. If Adsense requires you to add information, there should be a notice in your account. You do need to give tax information to Google - either your SSN if you are a US resident, or a form that states that US tax law doesn't apply to you. https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=10335
If it really is Google that is asking for tax info. then there is something you are not telling us. You obviously gave Google a US address upon signing up with Adsense, and if that's the case you are gonna have to start anew.
