This chapter explores how taxes shape the meaning of other payments and money flows in highland Bolivia. The concept ‘ecology of payments’ is introduced to describe the world of payments amongst the so-called informally employed in the city of Cochabamba. It explores how, for instance, receipts for commercial licence taxes and property taxes paid provide people with the right to make other kinds of payments, such as fees to local neighbourhood associations and unions. An ‘ecology of payments’ pays attention to the multiple links and dependencies between payments and the way they transform each other. This approach encourages a focus on the local impact of taxes paid, as opposed to the effect of taxes on long-term state–society relations. To ascertain the role of taxes within this ecology, the chapter also aims to understand how the concept of formality informs the power and character of different payments.

Tax is both an aspect of everyday life for people round the globe, bound up in political governance, and central to the organisation of our resources and any efforts to promote equality. While tax is studied across multiple disciplines, in anthropology it has received less attention. This introduction argues that an anthropological approach to tax, which centres ethnographic data and non-normative understandings of fiscal relations, is crucial to a comprehensive appreciation of taxes and key to building more equitable futures. The introduction is structured around three main questions: what is tax, what is taxable, and what do taxes do? It maps out why it is important to talk about tax now, the crucial influences of an anthropology of tax, the current landscape of this small but growing field of work, and the future of anthropological approaches to tax.
