<prompt> Human: To be clear - I am single, no dependents, and have max taxes removed from my paychecks.I switched jobs half way through the year -When I filled out the tax form for my first job, Turbotax made me happy, I was going to get an awesome tax return of approximate 5000.When I added my new job, it suddenly went to the negative.I thought this was odd especially since I am being taxed for what I would make if I had worked at the new place for a whole year, 28 in California - however my total income for the whole year of 2013 is actually in the 25 tax bracket since I switched half way; so I should actually get even more back due to this..correct?In any case - I thought, well maybe my new job is putting me in the negatives and I filled out my tax forms wrong when I signed up, well - when I removed my old job and only had my new job in Turbotax, what do you know, I will again earn around 5000!So...is turbotax wrong? I am getting maximum money taken out of my pocket, my total income is in the 25 range while my second half of the year was taxed at 28 - What solutions do I have?  <response>: With a basic return like this unless theres a lot you arent telling us its extremely unlikely Turbo Tax is wrong. Youre seeing this behavior because we have a progressive tax. When your income doubles you pay more than twice the taxes. Thats essentially what youre seeing when you go from one W2 to two.
