A common misconception is that undocumented immigrants avoid paying taxes. In fact, undocumented individuals pay sales and excise taxes, property taxes and, in some instances, personal income taxes. The study determined that at least 50 percent of undocumented households currently file income tax returns through the use of individual tax identification numbers, and many have taxes automatically deducted from their paychecks.

In a state like Alabama, the study found, the effective tax rate for undocumented individuals was 7.2 percent, 3 percentage points higher than the 3.8 percent effective tax rate that the wealthiest 1 percent pay in that state. Alabama is no way alone in this development; 42 states currently tax undocumented people more than their wealthiest denizens.
