<prompt> Human: Hi, Im filling out a Form W-4 and Im not sure if I should enter 0 or 1 in my Personal Allowances Worksheet.I currently have 1 job at a restaurant and I am filling out this form for my 2nd job that Im going to be working at. So Im gonna have 2 jobs but right now I only have 1. Im confused and dont know what should I enter. Please help.  <response>: Enter 0, because youll have two jobs.After a couple of months working at your second job, use this calculator from the IRS and if necessary adjust your W4 allowances.
