<prompt> Human: My employer gave me my w-2 today, and I made 5800 part time job, with 1 paid to federal tax, 359 to SS tax, and 84 to medicare. When I looked at my check stubs, I didnt notice anything out of the ordinary when it came to taxes but Im also kind of ignorant. My boss is looking up my paperwork to see what I claimed but Im pretty sure I just claimed 1, for my son. I dont have the paperwork in front of me and I dont know when shell get back to me but my husband and I are in panic mode now. Can anyone give me any sort of clue as to what might have happened? Update: apparently I claimed 3 and married, I dont remember why I chose to do that, but I did it. Oh well, extra money throughout the year. Thanks all. Assistant: Do you have any other income? If you only made 5800 for the year then it is likely you do not owe any taxes.Human: My husband made 32,000-ish this year. We had a 7k return and putting in the w-2 for my job dropped it to 5k, which isnt a huge loss but we were planning on putting an extra 2k in savings so this kind of puts a damper in our plansAssistant: Your job didnt do anything wrong then. You didnt understand how w4 calculations worked, and filled it out in a way to cause this. This doesnt cost you any money. It just meant you got more in each paycheck, instead of sending to the IRS, and getting it as a refund. Human: Ahh, crap. Okay. I guess Im thankful for the extra money during the year but bummed were not getting 7k. Ive always filled out my w-2s that way and never had it happen like this so Im just confused. Thanks for answering!  <response>: Its because you made below the taxable threshold, if this was the only household income. Instead though, your income is stacked on top of your husbands, and is taxed at the top of your tax rate, not 0 as the withholding calculations would assume, not knowing about the other income.
