Margot Crandall-Hollick is a principal research associate at the Urban-Brookings Tax Policy Center. Her research focuses on tax policies that affect low-income individuals and families, including refundable tax credits such as the earned income tax credit and the child tax credit. Given the increasing importance of refundable credits as income supports for low- and middle-income working families, Crandall-Hollick’s work also examines the administration of these programs, both for taxpayers and for the Internal Revenue Service. Before joining the Tax Policy Center, Crandall-Hollick spent 16 years working on Capitol Hill advising policymakers, most recently at the Congressional Research Service and before that for Senator Christopher J. Dodd. She holds a BA in mathematics from Smith College and an MSc in international political economy from the London School of Economics.
