<prompt> Human: Long story short...I updated my federal deductions to 0 from 2 early last year in the online portal for work. I went to do my taxes today and I owe about 2,000 more because of this. I called payroll and they said the changes I made in the system didnt download to the server thus Payroll never changed my W2. But my personal page in the portal says 0 deductions. So mad...is there anything I can do?  <response>: Theres nothing you can do right now, only a lesson for the future: Pay attention to your paychecks and deductions. A red flag should have been that your paychecks did not go down in amount when you switched allowances. Compare your paycheck stub to what paycheckcity.com says you should be getting.
