【 摘 要 】

This paper examines the taxation of labour income in five key emerging economies: Brazil, China, India, Indonesia and South Africa (the “BIICS” countries). The paper highlights the key features of the taxation of labour income in these countries, and then uses this information to model the tax burdens on labour income in each country following the OECD's Taxing Wages methodology. Average and marginal tax wedges in Brazil and China (Shanghai) are found to be similar in size in 2010 to those of many OECD countries. In contrast, India, Indonesia and South Africa (as well as rural China) impose very low average and marginal tax wedges compared to the vast majority of OECD countries. These relatively low tax wedge results are not altogether surprising given that these countries also currently have lower tax-to-GDP ratios than the OECD average. However, the results suggest that, in the long-term, reforms will be necessary in most of the BIICS countries if the labour income base is to significantly contribute to funding the substantial increases in public expenditure, particularly on infrastructure and social insurance, that will inevitably come as these countries continue to grow.
