<prompt> Human: I use turbotax to file my taxes. Nothing has changed in my life or job since last year, but last year I got 777 for my 2016 federal tax return. Now it is saying Im only going to get 78 for my 2017 return. I made 22,243 in 2016 and 40,865 in 2017.Is there something I am doing wrong or does that sound right? Im very confused!! Edit: I should have clarified the following: I was a student for most of 2016. I started my job in July, so i only got paid for half the year. My salary actually stayed the same in 2017, I just worked a full 12 months.  <response>: Nothing has changed in my life or job since last year ...

A person making twice as much is going to owe more taxes. The amount that is withheld to pay those taxes depends on your W4 form. Deductions and credits also play into this.
