I think my employer has been taking out Federal tax, but hasn't reported it correctly on my pay-stub or W-2's. I don't know if this was intentional or not. Can the IRS confirm if my employer withheld Federal income tax, but didn't accurately report it on my W-2?
Yes, the IRS will most likely automatically adjust your return, if your employer has paid in more income taxes for you, than what was reported on your W-2. However, you can check this too and ask your employer for a corrected W-2, if you haven't filed yet.
You can also check your pay stubs. Your pay stubs are required to report every detail about your pay and your taxes. If you can find (or request from your employer), your last pay stub for 2017, it should show the year-to-date totals for your taxes and you can match the amounts to your W-2.
The following 4 categories explain each of the amounts/taxes on your pay stubs and W-2.
Comment with more info, if you still have questions.
Only if the employer reported the right amount to the IRS in the first place. Your paychecks net amount paid doesn't match the check you got or the deposit? Why do you think it's wrong?
