I’m a member of Google Adsense. It’s an official Google affiliated marketing tool that pays people to publish ads on their site or alongside their videos. I recently made $10 and they put my payments on hold. In order to release those payments, I “must submit my tax information as required by some federal and state governments.” I was instructed to fill out a IRS W-9 form. In the form, it asks my SSN. Is it safe to put in? Google says that the form is encrypted by SSL, but I am unsure of wether I should or shouldn’t submit my SSL number.
