Abstract

This article focuses on the justification of taxation, in other words the principled rather than the technical aspect of taxation. We first show how democracy is on the one hand required for legitimate taxation, and how on the other hand democratic communities are dependent on taxation, and argue there is no vicious cirle. We then present a typology of ways of justifying taxation, according to which taxation can base its legitimacy on (1) meeting basic needs, (2) financing public goods, (3) redistribution, or (4) (dis-)incentivising certain types of conduct. We then discuss the applicability of each of these types of justification on the global level, arguing that all of them do apply to the global level. The article further concludes that different normative justifications guide us towards different designs of taxation in practice, so the background justification has to be made clear, especially when designing new taxation systems.
