<prompt> Human: I am a 19 Year Old College Sophomore with 5,309 TOTAL Income in 2015 - Do I need to file taxes? Mostly from selling on Amazon.Since the Amazon business was NOT profitable I broke even, do I still need to add that in?I have never made this much money and have never had to file taxes. Can someone guide me?  <response>: having an income of 5,000 but breaking even sounds more like you had sales of 5,000 but a profit of next to nothing.Calculate your business profit price sold for - cost of goods - amazon and credit card fees and that is your income.Then file taxes based on that amount. You made money, so you need to claim it. chances are you will likely not owe anything since it was a small amount that can be negated with standard deductions.
