<prompt> Human: My GFs just last week completed her taxes and it came out that she owed 2200 back for federal taxes. The women that completed her taxes informed her maybe you should go back and change you taxes from 1 to 0 so you dont have to pay as much. My GF contacts her job and finds that he job put her in as a 3!!!Im trying to figure out what our next plan of action is for her offices mistake  <response>: There is no course of action. The money wasnt withheld for the Income tax and she received it on her paycheck. You might have her ask to see a copy of the previous w-4 which she should have filled out when she started. But just have her fill out a w-4 and give it to the employer, that way they can adjust it and since were not to far in the year hopefully it wont affect her too much.
