This report explores the behaviors and outcomes related to savings and financial well-being of low- and moderate-income (LMI) tax filers in the United States. Findings from research conducted by Prosperity Now, the Social Policy Institute at Washington University in St. Louis and SaverLife (formerly EARN) during the 2019 tax season are presented. This analysis is unique in that it compares tax filers' outcomes over time across three different tax-filing and savings program platforms: volunteer income tax assistance (VITA) sites, online tax filing through the Turbo Tax Free File Product (TTFFP), and SaverLife's saving program.
