According to the Institute on Taxation and Economic Policy, it has been estimated that undocumented workers contribute $11.74 billion in state and local taxes. Also, granting legal status to all undocumented immigrants in the United States as part of comprehensive immigration reform and allowing them to work legally would increase their state and local tax contributions by an estimated $2.18 billion a year. Their nationwide effective state and local tax rate would increase to 8.6
percent.

Undocumented immigrants make a huge impact in the economy of this country, and deportation could result in a substantial hit.
