In recent years, investments in technology have resulted in an exponential growth of AI/robots. It is argued that some of these innovations are able to outperform and replace humans in various types of jobs. Accordingly, concerns regarding government revenues have been raised, as AI/robots could trigger widespread unemployment with the result that less tax revenue will accrue to the government. This contribution, as a start, analyses whether or not this is truly a concern. In order to do so, the authors map the Industrial Revolution(s) that humankind has witnessed and then conduct a literature review of economic and demographic studies relevant to the debate. The economic studies indicate two different directions, that is, some argue that AI/robots (Industry 4.0) will increase human jobs whereas others argue that jobs could disappear. At the same time, the demographic perspective indicates that a purely economic employment-focused view of AI/robots is bound to lead to inconclusive results. Assuming that this is a probable concern, the authors summarize selected measures taken by governments as well as the various options that have been considered in academic literature to introduce taxes on AI/robots. Subsequently, the authors analyse the various "taxing" options from the perspective of commonly accepted tax policy principles applicable to electronic commerce (Ottawa Taxation Framework conditions). This analysis indicates that several proposals (e.g. proposals that treat AI/robots as independently taxable subjects or proposals that attribute income to owners of AI/robots) breach the principles of (i) neutrality; (ii) simplicity and certainty; (iii) efficiency; (iv) effectiveness and fairness; and (v) flexibility. Thus, such measures should not be pursued. The authors also conclude that, at this stage, targeted taxes on AI/robots should not be introduced, as this would also be contrary to the measures taken by governments globally to promote research and development (R&D) (input or output incentives). This contribution therefore suggests that governments need to be proactive rather than reactive in this area. This could be achieved by monitoring the impact of AI/robots on a regular basis, and if the trend indicates that jobs are disappearing or revenues are declining, then the article suggests that states raise funds from an earmarked education tax. The funds raised from this tax, among other objectives, should be used to finance and foster professional educational programmes to reskill workers, besides assisting and guiding them to transition into new roles. However, a national measure may not be sufficient to tackle the issue (issues) at stake, especially in light of the demographic perspective discussed in the contribution. Thus, considering some jurisdictions may not be in a position to implement or fully benefit from an education tax, the authors also discuss the possibility of implementing a global fiscal redistribution mechanism (multilateral solution) from developed (surrender jurisdictions) to developing countries (recipient jurisdictions). The latter, depending on its scope, could be in the form of a global education tax or more broadly a planetary tax.Full-text Paper.
