As in many high income countries, VAT systems in low and middle income countries (LMICs) are often characterised by different tax treatments for different types of goods and services. Often, reduced rates of VAT and exemptions (“preferential rates”) are granted on equity grounds, for goods and services that are thought to take up a greater proportion of the budgets of poorer households. Given typically limited capacity to redistribute through the direct tax and benefit system, it has been suggested by some economists that such rate differentiation might be the best way for governments to transfer resources to poorer households.

As in high-income countries, reduced rates of VAT and VAT exemptions (“preferential VAT rates”) are a common feature of indirect tax systems in LMICs. Many of the goods and services that are granted preferential rates – such as foodstuffs and kerosene – seem likely to receive such treatment on the grounds that they provide a means for the government to indirectly target poorer households, for whom such expenditures may take up a large proportion of their total budget.

The simplest form of value added tax (VAT) – and the form often advocated by international organisations – is one with a broad base and a single (‘uniform’) rate. In practise, most countries exempt and/or apply lower VAT rates on certain categories of goods and services. In this note authors summarise the pros and cons of such ‘VAT rate differentiation’ that are highlighted in the economics and taxation literatures, paying particular attention to the applicability and relevance of each factor for low- and middle-income countries.
