<prompt> Human: Last year I earned 25835 paid 3290 in federal income taxes and got back 1605.This year I earned 38232 paid 5081.92 and credit karma is estimating that I am getting back 1794. I know this may not be entirely accurate but using the numbers from last year put me at an expected return of 2600. Is there something wildly wrong with my assumptions?  <response>: Your income went up significantly. That means the amount of taxes you pay goes up as well.
