This paper tests whether providing information about the Earned Income Tax Credit (EITC) affects EITC recipients' labor supply and earnings decisions. We conducted a randomized experiment with 43,000 EITC recipients at H&R Block in which tax preparers gave simple, personalized information about the EITC schedule to half of their clients. Tracking subsequent earnings, we find substantial heterogeneity in treatment effects across the 1,461 tax professionals who assisted the clients involved in the experiment. Half of the tax professionals, whom we term "compliers", induce treated clients to increase their EITC refunds by choosing an earnings level closer to the peak of the EITC schedule. Clients treated by complying tax professionals are 10% less likely to have very low incomes than control group clients. The remaining tax preparers generate insignificant changes in EITC amounts but increase the probability that their clients have incomes high enough to reach the phase-out region. Treatment effects are larger for the self-employed, but are also substantial among wage earners, suggesting that information provision induced real labor supply responses. When compared with other policy instruments, information has large effects: complying tax preparers generate the same labor supply response along the intensive margin as a 33% expansion of the EITC program, while non-complying tax preparers induce the same response as a 5% tax rate cut.
