My client has many companies--call it 4 companies. Each company pays him $100,000.HE RECEIVES ONE W2 from the PEO.

Federal, SS and Medicare wages are $400,000 on his one W2. SS is wrong.

PEO is doing it wrong.

If they gave him 4 W2s, each would have SS of $100,000 and he would get credit for the tax on wages over $142,800, or $257,200.
