The Center on Budget and Policy Priorities. May 2020. CBPP outlined specific expansions the federal government should make to the federal EITC and CTC ahead of the 2021 tax season to boost the economy and avoid spikes in poverty. These expansions include increasing the value of the EITC for workers without dependent children, making the CTC fully refundable, and allowing recipients to use their 2019 or 2020 tax returns to calculate their credit.
