I thought I'd explained that I understood the invalidity of this potential client's approach. You just repeated all the underlying reasoning.

What I asked was how to fix it. You indicated that I could not just ignore the "payroll" and proceed to file using true income and somehow applying the withholdings to 1040 categories. You seemed to indicate that the individual would have to work with ADP to reverse the several years of reporting payroll to him. Given the lack of understanding of the situation by the initiator of this thread, I don't imagine that this situation is unique. Do you know if ADP has the willingness and the capability to do a full multi-year reversal?
