I am self-employed, so looked into it. The employer’s portion remains at 6.2% of 106,800, for a total of 6621. The employee’s portion is 4.2% of 106.800, for a total of 4485.
difficult to believe, but I take your word for it...they are often unusually tricky in their wording....A cap of $106 and change is different from a max of $6621 withheld....
