<prompt> Human: Like the post says, I just got my first paycheck from my new job permanent, full-time, salaried. Since I only worked three days, my gross pay was only about 489, but when I looked at my pay stub, they only took 4.84 of that to pay federal taxes. Social Security, MedicareMedicaid, and State taxes all looked normal, ranging from 6-21. Im filing as a single adult with one job, so I have 2 federal deductions and 1 state deduction, but theres no way a 1 tax is correct. I sent a message to HR yesterday, but havent heard back. It was a low-level HR guy though, so I may escalate to the next person if I dont hear back by the end of tomorrow.My concern is that I already cashed the check, since Im kind of in dire financial straits right now. Ifwhen they realize its a mistake, will they be able to take the missing tax out of my next paycheck? Or will I have to wait until tax season to pay for it?Thanks in advance guys!  <response>: A lot of payroll services just take your paycheck and extrapolate to the entire year.So suppose you were paid monthly, and your paycheck is 489. That means you make 5868 per year 489 12, and therefore pay basically no federal taxes.But wait, I only worked 3 days of the month. This isnt-- The software doesnt care.
