I've been told by somebody that if I was not required to fill out a W9 for the money I've made online through GPT sites that I'm not required to pay taxes on this money. Can anybody with a legal background confirm this? Obviously I'm not going to take your word as definite legal advice, but if I get the strong opinion of it not being required of me I might find a lawyer around here that could better advise me (hopefully for free if I know anybody that knows a tax lawyer or I could exchange some simple SEO work for legal advice). At first I was thinking that it was complete BS but now I realize that yeah, it does make sense. If I don't fill out a W9 then the company paying me is paying taxes on the money I'm getting and therefore the money is being accounted for. If I were to pay taxes, it'd be taxed twice. I'm not 100% positive, but the money may or may not be coming from the USA. The site is supposedly stationed in the Netherlands; however, everything else seems to be United States. I'm not talking a few hundred bucks a year here so it's not like it's some small matter of paying $100 tax or not. If I have to pay taxes on this I stand to lose at least $6,000 or more.
