The GST that you collect from customers is not your money, it's the government's. You are collecting it on their behalf. It goes into the till as part of the sale, but for book keeping purposes is kept separate and does not constitute part of your profits. You "pay" income tax on profits. It's not correct to say you "pay" GST on profits. As traders, we do not provide any services nor sell any goods. The gst is a goods and services tax, you don't have to remit it if you don't collect it. The idea of paying GST on trading profits is nonsensical.
