Form 4029
On Form 4029, the Preparation of Form W-2 section of the Instructions to Employers tells you
to specify Form 4029 in the box marked "Other:" Do not make any entries
in the boxes for Social Security wages, Medicare wages, Social Security tax withheld, or
Medicare tax withheld.
Note: The employer must be
identified as a Form 4029 Employer by selecting the Form 4029
Employer check box on the Employee Year End Parameters
page.
See Updating employee year-end parameters.
After selecting the check box for the applicable legal entity, W-2 Reporting checks the employee configurable fields set up for printing Form 4029.
