@shubert  Off the top of my head, a common cause of this would be payroll items that lower the amount in box 1 of W2s and W3s; retirement plans, for instance, would reduce gross pay for the purpose of wages subject to federal income tax. This can cause what appear to be discrepancies between payroll reports and W3s, whether they are actual discrepancies or not.

Unfortunately, the kind of images that would make this easier to diagnose are not generally the kind you should be sharing online.

I would advise reaching out to your accountant regarding this directly. More likely than not, they have some manner of QB account and can either access your information directly or otherwise give you the proper guidance.
