Since most of us are probably self employed, we don't have jobs that take taxes out for us. So we have to do that ourselves. On top of that, those of us in the US, will have to pay extra tax for being self employed as they call that a business. I try to put a quarter of it in savings, even if I don't make as much that week. I always take a quarter out. This way I'm covered when tax season comes and I may have some money left over.
