I am 7 months into a new job and found out this week that despite me never having issues at previous employers, doing my own taxes, and being very familiar with how to fill out my W-2 and W-4, my employer has not withheld any federal tax from my paychecks. When I contacted HR about it, all I got back was “It looks like you haven't paid any federal tax. That will be a problem for you come tax time.” When I asked what I should do all they did was give me some sort of tax calculator and told me to figure out as best I can how to calculate what I should withhold on my own to pay at tax time. After doing some research online it looks like this is actually illegal for them not to withhold federal tax and to not help correct THEIR mistake. I have a meeting later this week and plan to bring all the legal ammo I can. Any advice and resources are much appreciated.
