This paper uses two studies to examine taxpayers' knowledge of tax incentives for charitable giving and also explores the consequences of this knowledge on charitable giving decisions. The first study surveys 600 US taxpayers to establish a baseline understanding of how making a charitable contribution affects taxpayers. In the second study, we conduct an experiment with 201 US taxpayers in which we manipulate the knowledge of taxpayers by providing an educational intervention; we also measure, if, how much is donated in a hypothetical scenario under various tax deductibility conditions. The first study indicates fewer than half of participants understand the basic principles of how charitable donations affect tax liability. Our second study reveals that a short educational video is extremely effective at improving taxpayers' understanding and helping them accurately estimate the tax benefit associated with charitable giving. However, through moderated mediation analysis, we also show that participants who received this educational intervention and accurately estimated the tax benefits in turn decreased their charitable giving. We conclude that the majority of US taxpayers do not understand whether they benefit from certain deductions and may be overestimating the benefit they receive from charitable giving, resulting in giving more than they intend.
