IRS estimates that about 6 million unauthorized immigrants file individual income tax returns each year.
[20] Research reviewed by the nonpartisan
Congressional Budget Office indicates that between 50 percent and 75 percent of unauthorized immigrants pay federal, state, and local taxes.
[20] Illegal immigrants are estimated to pay in about $7 billion per year into Social Security.
[21] In addition, they spend billions of dollars per year, which supports the US economy and helps to create new jobs. The Texas State Comptroller reported in 2006 that the 1.4 million unauthorized immigrants in Texas added almost $18 billion to the gross state product, and contributed $1.58 billion in state revenue, while costing the state about $1.16 billion in services used.
