<prompt> Human: I havent worked all year and just started my job in July. I understand my employer extrapolates what my annual income will be and taxes me accordingly but come tax time, I will only have made half that amount. Since Im being taxed at a much higher rate, is there anything I can do on my W4 like claim more exemptions so I dont have to wait until next year to get my money back? I dont want to do anything illegal of course which is why Im posting here first.  <response>: Use the IRS withholding caluculator.
