When I started my job, I filled out a W-4 and claimed 3 allowances. While going over my pay check information, I noticed at about 1 year ago, they stopped taking out federal taxes each check.
I went in and they said the W-4 on file that I submitted "Total number of allowances you’re claiming: 3", but they said the computer says I'm at "6" and they would not explain why.
Assuming I correctly filed my taxes each year, does this have some implication of any kind, such as I paid too many taxes? Or the employer has not been paying enough of their contribution to the taxes?
