After you file

Exactly - they didn’t withhold much. I also worked part time for the first time ever last year and I thought my witholdings were lower because I made less. This is where the hiccup is drawn from.

If my W4 shows zero or one but my w2 shows three  allowances, what’s the next step on getting this adjusted?

Payroll does not have the right to just adjust or input the wrong allowances either. . .

Tomorrow I’m stopping by hr to view my documents and I need to know is there any resolve if payroll made a mistake with inputting my witholdings.
