Evidence shows that individuals do not always take tax attributes into account when making their choices. We focus on tax relief for charitable contributions. Although rational donors should view a match and a rebate of the same value as being equivalent, survey evidence shows that nominal donations are more likely to adjust in response to a change in the rebate than to a corresponding change in the match. We argue that these patterns are consistent with the predictions of a model of rational inattention, whereby a majority of individuals choose to process rebate changes while forgoing to process match changes.
