<prompt> Human: Im working though my 2017 taxes, and I owe several thousand dollars. I live in Indiana in the United States. Got a raise last year, but not enough to just a tax bracket. I didnt get married, buy a house, I have no change in dependents. Last year I got 400 back. I am just have trouble understanding this. If you need more info I can provide it within reason.Update: So I found a form 8959 that has an extra digit in my medicare wages and tips. Who do I contact to correct this? Do I open an inquary with the IRS or something?  <response>: Well since you listed no numbers or information theres no way that we would know why you owe so much.
