So please explain how an illegal can pay state or federal income tax when they do not have a SSN or TIN?

A lot of the wages for illegals are handled as cash under the table – Cash = not track-able. Note that I highlighted income which is not the same as sales tax.

Actually, a lot of illegals are paid using stolen SSNs these days. From what I’ve read, probably more than are paid the old way via cash under the table. They’re paying the taxes — they’ll just never see any benefits.
