Abstract

Are reforms towards individual taxation politically feasible? Are they desirable from a welfare perspective? We develop a method to answer such questions and apply it to the US federal income tax since the 1960s. Main findings are: As of today, Pareto-improvements require a move away from joint taxation. Revenue-neutral reforms towards individual taxation are not Pareto-improving, but attract majoritysupport. Such reforms are rejected by Rawlsian welfare measures and supported by ones with weights that are increasing in the secondary earner’s income share. Thus, there is a tension between the welfare of “the poor” and the welfare of “working women.”
