Study estimates that illegal immigrants paid $11.2B in taxes last year, unlike GE, which paid zero 

ITEP estimates that households that are headed by undocumented immigrants (which may include members who are U.S. citizens or legal immigrants) paid $11.2 billion in state and local taxes last year. That included $1.2 billion in personal income taxes, $1.6 billion in property taxes and $8.4 billion in sales taxes.New Yorkis fourth in the country in tax revenue - $662.4 million - from households headed by undocumented immigrants, after California, Texas and Florida.

"These figures should be kept in mind as politicians and commentators continue with the seemingly endless debate over what to do with unauthorized immigrants already living in the United States," ITEP wisely advises."[These] immigrants - and their family members - are adding value to the U.S. economy; not only as taxpayers, but as workers, consumers and entrepreneurs as well."They pay sales taxes and property taxes - even if they rent, ITEP said. At least half of them pay income taxes. And, I believe, if they were ever legalized, close to 100% would do the same. "Add this all up," ITEP said, "and it amounts to billions in revenue to state and local governments."

[I CANT VERIFY THIS,HOWEVERTHERE HAVE BEEN FEW STUDIES SUGGESTING SAME THING,ON THE FLIPSIDE UNDERSTAND ALSO THAT ITEP DOES RECEIVE FUNDING http://itepnet.org/about/funding.php

FROM SOROS OPEN SOCIETY,FORD FOUNDATION ETC...BUT IT DOENST EMAN THE STUDY IS INCORRRECT,ILL LOOK FOR OTEHR STUDIES LATER ON,AND SEE IF WE CAN CORROBORATE THESE CLAIMS..ON THE FACE OF IT,THEY SOUND LOGICAL,AND QUITE PROBABLE..
