Okay so, I've been a youtube partner from october 2007 to the present day today. I am 18 years old, I live in Canada and when i started making these videos i got paid very little. However, over time it starting growing in popularity and i got millions of hits, ect. I am currently very worried because i have just found out about this whole tax thing? I may have to claim all the money I've made? It says from October 2007 to today I have made 59,000 dollars. Every month i've gotten checks to spend and its just been my job since. My mother keeps telling me the government may find out about this. If so, I just don't know what to do and I need some advice on this. Thanks.
