<prompt> Human: I live and work in California Assistant: If you overwithheld, yes, you will get back what you overwithheld to the extent you didnt otherwise owe. Keep in mind though that its not just federal income taxes. Its state income taxes and FICA taxes as well.Human: Do I have to calculate the bonus payments vs regular wages myself or is it reflected on my W2? How do I know how much I got back?  <response>: The IRS doesnt care whether certain income was a bonus or not. They just look at how much you had in wages which includes normal wages and wage bonuses, determine how much tax you owe on that total, and compare it to how much you had withheld throughout the year.
