<prompt> Human: I work a salaried job in Arizona. Monday through Friday, 9-5. This is a support position and there are six people on my team.Every weekend, on a rotating basis, one of us provides support to the whole company over 1200 workers. Were basically subject to receive support calls from 6am-5pm on Saturday and Sunday. That is 22 hours per weekend, every six weeks for me because there are six of us.I get paid for this rotation, thankfully. 250 per day, totaling 500 for a typical two day weekend.However my issue is that on my pay statement, the 500 paid for the weekend is labeled as a bonus just like the yearly bonus that I receive. My understanding is that the IRS taxes yearly bonuses quite heavily, and I suspect that my 500 weekends are being taxed like a bonus, because it is labeled that way on my paystub, even though it is money earned for time worked.Is my employer labeling my pay for weekend work incorrectly? Am I paying extra tax because the IRS sees the extra 500 as a bonus?  <response>: Neither bonuses nor overtime are taxed any differently than normal income, but may be withheld differently.
