<prompt> Human: I claim 2 on my exemptions, and havent owed yet. I dont mind breaking even or getting a small return, but Im working more overtime than usual, and Im curious if it will put me in the red come next tax season. I work in EMS, and already have a built in 80 hours of overtime a month, on top of about 48 more that Ive been getting.  <response>: If anything, overtime is going to cause higher-than-normal tax withholding, i.e. you will owe less in the end.But if overtime is much more frequent than regular time, you may owe more, since your paychecks during weeks of 40hr dont withhold enough.
