The Institute on Taxation and Economic Policy, a nonprofit, nonpartisan think tank, proposed that states and localities can significantly increase revenue collection by legalizing undocumented immigrants.
According to an ITEP report, undocumented immigrants collectively pay an estimated $11.64 billion in taxes a year. The state of California, home to more than 3 million undocumented immigrants, collects $3.1 billion annually from them in state and local taxes.
