I just calculated my income tax on my T5 here in Canada, i'm not sure if it's the same in the US but I owe the governemnt 700 dollars. I have 2 other jobs aside from seeling on ebay but I've never had to pay this much. I was just wondering if every time we make a paypal deposit or a money order deposit into our accounts, does the governement know where it's coming from and is it considered as past of our income?
