<prompt> Human: Hey guys, I just graduated college this past December. I worked 3 partime jobs, including a grocery store, a valet position that paid hourly and tips, and a paid internship. My combined earnings are somewhere between 30-35k in 2014.I live in NY, am claimed as a dependent by my step father, and had no allowances claimed for any of my W-4s. My step dad filed for me and I now owe Federal 242 and I owe state 494. Can anyone explain how this is possible? Its been a tough month financially and this is a bit frustrating. Thank you so much guys.  <response>: When you have multiple jobs sometimes you need to have extra withheld if you dont want to owe. Each job withholds as if thats your only job. Use the IRS withholding calculator in the future.
