<prompt> Human: I just noticed my biweekly check took out 60 more than it would two single weeks of pay. I just started a new job and for the first week we got paid only for the first week which was around 500. Now, they started to pay us biweekly and noticed my check is 929. After some calculations, they took out 60 30 took off every week extra than it would if they were to make single week payments. Whats going on? Why are they taking out more money biweekly than single week of pay?  <response>: even though your first paycheck was only for 40 hours, the computer that estimates you withholding was told that you will make that every 2 weeks - it didnt know that it was only for one week.So before the computer thought you wont make as much over the year, and therefore didnt need to pay as much in taxes, however the newer paychecks are closer to what you will actually make, and therefore are more representative.
