Someone please explain what is going on. Presumably, an illegal cannot get a valid social security card. So I guess most have forged cards with invalid numbers. Are these Senators trying to tell us SS keeps track of contributions that are made to each of these invalid numbers?
I'm sure the IRS does. If the number they use matches one that exists, whoever's number that really is will get stuck with the back taxes - plus penalties and interest. It will be up to them to prove otherwise.
Years ago a friend of mine was notified he owed tens of thousands to the IRS for jobs in states he never lived in. Apparently someone was using his SS number for jobs. Don't know if he ever got it straightened out. He died of cancer two years after he was first notified. His family probably got stuck fighting it.
So, not only are the illegals not paying any of the payroll taxes like SS and medicare and medicaid, but if they are using a number that does exist out there, some American taxpayer is going to have a hell of a time fighting the IRS. - Another benefit of cheap labor. /sarc
