Grounded in the belief that California has an important responsibility to its low-income residents, the Prosper California Coalition (formerly the CalEITC Coalition) originated with the campaign to create a California Earned Income Tax Credit. Modeled on the federal credit of the same name, the CalEITC is another method to financially support low-income Californians, including those ineligible to receive the federal EITC or other credits.
California established theCalEITC in 2015. Further successful efforts include the Young Child Tax Credit (2019) and, most recently, the Foster Youth Tax Credit (2022).

The Coalition continues its advocacy by fighting for:
- Full expansion of these credits to support all individuals and households in need
- Elimination of barriers that limit access to claiming credits
- Fully-funded programs that provide tax and tax credit outreach and education, ensuring eligible Californians receive all the money they are owed
- Working collectively on new and necessary tax and cash policies that will better assist struggling Californians and put them on the pathway to financial security
ECPCA engages in lobbying and direct and grassroots advocacy activities via the GRACE End Child Poverty Institute.
