<prompt> Human: Im 17, I work 60 hour workweeks, I am the sole provider for my 14 year old sister. I chose 0 on my taxes and I just learned that if I make a certain amount of money, even though Im a minor, Ill still owe a lot at the end of the year. What the hell do I do to avoid paying out a huge amount? Im in no position to do that and Im scared  <response>: Spend an hour a week on personal finances, starting with just reading how the tax system works. As part of time learning about it, learn how to use excel to do basic calculations estimating what you will owe.Then once you understand the basic concepts, you can move on to budgeting, tracking expenses, and saving.
