<prompt> Human: I recently started a new job and when I filed taxes, I found out I owed a pretty large amount of money to the Federal Government. Turns out my employer wasnt withholding any money for FIT Im not an independent contractor. I didnt file for any exemptions - I didnt claim any dependents. Pretty sure Im still on the hook for paying the money back, but is there anything else I can do besides resubmitting a W4 and yelling at the HR Dept?  <response>: First, ask to see a copy of the W4 they have on file for you. Assuming you did not check exempt, they probably should have been withholding taxes. Dont yell at HR unless they are also responsible for inputting that info into the payroll system. But do require an explanation from them, and then make it a habit to check every single paystub from here on out. You are responsible for the taxes owed, regardless of what HR or payroll did.
