<prompt> Human: Started a new job April 2 with a 70,000 salary. My first paycheck for one week of work was 1346 gross with 18.98 deducted. My second paycheck was for exactly double the amount of time and double the gross, 2692, yet 26 was withheld. Why did my California and Federal income tax amounts leap from 27 and 99 to 142 and 334? Greatly appreciate any feedback!  <response>: Because you were paid moreWithholding calculations dont look forward to what you will normally earn, they look at what you earn during a particular pay period and since your first paycheck wasnt a full check it was withheld at a lower rate.Or to put it more clearly, your first check led the withholding calculations to think you made 35kyr instead of 70kyr. Your actual salary is not part of the calculations.
