This policy brief provides estimates of the number of tax filers who qualify for the new California EITC and the amounts they will receive. It does so by modeling the California EITC as if it had been implemented in tax year 2013. We find that an estimated 614,000 tax filers and their family members (1.97 million individuals) could benefit from the credit. We then examine the extent to which such a credit might reduce poverty and narrow poverty gaps among recipients and their family members. An estimated 364,000 of the 2.20 million individuals living in deep poverty (as measured under the California Poverty Measure) are eligible for the state EITC, with an average family benefit of $464. Roughly 1.4 percent of California’s deep poverty population (about 16,000 adults and 15,000 children) would be moved out of deep poverty if they made use of the state credit. Finally, we compare the enacted policy to other potential program expansions in terms of cost, reach, average benefit, and poverty reduction.
