Tax administration improvements have contributed significantly to a doubling of China’s tax-to-GDP ratio and the substantial reduction in taxpayers’ compliance costs since the mid-1990s. This paper describes the key features of China’s tax administration and their evolution over the last 20 years. It also identifes emerging challenges to the tax system and areas where further tax administration improvements are needed to sustain tax revenue and reduce taxpayers’ compliance costs in the future.

There is a widespread concern that, in some parts of the world, governments are unable to exercise effective authority. When governments fail, more sinister forces thrive: warlords, arms smugglers, narcotics enterprises, kidnap gangs, terrorist networks, armed militias. Why do governments fail? This book explores an old idea that has returned to prominence: that authority, effectiveness, accountability and responsiveness is closely related to the ways in which governments are financed. It matters that governments tax their citizens rather than live from oil revenues and foreign aid, and it matters how they tax them. Taxation stimulates demands for representation, and an effective revenue authority is the central pillar of state capacity. Using case studies from Africa, Asia, Eastern Europe and Latin America, this book presents and evaluates these arguments, updates theories derived from European history in the light of conditions in contemporary poorer countries, and draws conclusions for policy-makers.

The excessive complexity and burden of the Brazilian tax system, riddled by cumulative indirect taxes and heavy payroll contributions, have led to an accumulation of fiscal incentives aimed at reducing its burden on taxpayers and productive activities. Federal and subnational tax expenditures currently stand at over 5 percent of GDP. Rationalizing them can only be comprehensively feasible in the context of a broader sequenced tax reform, and could reduce resource misallocation and income inequality, as well as provide new revenues.
