Presumptive tax regimes (also known as simplified tax regimes) intend to reduce tax compliance costs for micro and small businesses (and enforcement costs for the tax administration) while levying a lower tax burden as compared to the standard tax system. This working paper compiles detailed information on the presumptive tax regimes existing in a selection of OECD and non-OECD countries, identifies common practices adopted across the countries examined and provides multiple examples of best practices observed in these regimes. These examples can serve as guidance to policy makers and tax administrations to strengthen particular features of the presumptive tax regimes implemented in their jurisdictions. Lastly, the paper highlights the main challenges generally observed in the presumptive tax regimes under study, which might undermine the role of these regimes in incentivising business formalisation and strengthening tax compliance over time.

Using panel data for Indonesia, Malawi, Peru and South Africa, this paper investigates the relationship between transitions to formal employment and workers’ labour income. It shows that transiting from informal to formal employment increases the probability of improving workers’ labour income in both absolute and relative terms. However, income gains from formalisation do not accrue to all workers equally. Switching to formal employment has the greatest potential to improve the labour income of the richest workers. The chances of improving the labour income of the poorest workers through formalisation are slim. Transitions between formal and informal employment affect income gains and losses differently for men and women, older and younger workers, and workers with different levels of schooling. The effects of labour market transitions on income changes are considerably greater in magnitude than other life events such as a births, separation, or death of a partner or spouse.

Productivity growth has been falling for a decade, hindering improvements in living standards. Low productivity reflects, firstly, poor infrastructure in telecommunications and transport. Secondly, the regulatory environment is not always business-friendly and often raises obstacles to firm entry, exit and expansion. Combined with weak competition in important sectors, this has led to lower private investment levels, particularly, business R&D. Finally, the educational and health care systems have been unable to supply adequately skilled workers across the country. To improve productivity, public investment needs to become more effective, notably by strengthening the selection process for large infrastructure projects. A more pro-competitive business environment would let productive firms grow and foster innovation. Widening and reducing inequalities in access to education and health care would reduce skill shortages.

This paper aims at quantifying the macroeconomic and distributional impacts of product market reforms and additional public investment using a DSGE model. The model reflects specific features of the South African economy. Tradable and non-tradable product markets are modelled separately, and a segmented labour market is designed to reproduce the labour market duality in South Africa between skilled and unskilled workers. The role of public investment on total factor productivity and its financing modality are taken into allowing the quantification of the net benefits of reforms. Our results show that enhancing competition in the non-tradable sector has a short run recessionary impact while deregulating the tradable sector is expansionary. Overall, the latter has a bigger impact on GDP. From a distributional perspective, a product market reform in both sectors benefits all income deciles. Finally, additional public infrastructure investment, either financed by raising VAT or capital income tax, increases GDP in the short-term less than product market reform in the tradable sector but is more expansionary in the long run, so a combination of both reforms would boost living standards.

The Covid-19 crisis has exacerbated the already deteriorating fiscal situation in South Africa. The current consolidation strategy, based on spending cuts and reprioritisation of spending items, has reached its limits and is insufficient to stabilise the debt ratio in the medium term and fund unmet public services needs. The tax-benefit system needs to be redesigned to create fiscal space in the years to come to finance growth-enhancing reforms and to reduce inequalities. The challenge is to generate additional revenues without generating inefficiencies or exacerbating inequality. Income taxes represent around half of total tax revenues, but are levied on small tax bases, partly reflecting the unequal distribution of income. Only the value-added tax has a relatively broad basis combined with a moderate tax rate. There is some scope to raise revenues further while reducing existing tax distortions, notably by broadening the base of corporate and personal income taxes, as well as consumption taxes. Taxes with a less harmful impact on growth, such as property taxes, are limited by the inefficient municipal rates system. There remains scope to further increase environmentally-related taxes.

Corporate tax incentives reduce investment costs for businesses, which may affect investment and location decisions. They apply through different designs and interact with countries’ standard tax systems, often making it difficult for tax policy makers and researchers to compare their generosity and assess their impacts across countries. This paper develops a methodology to calculate forward-looking corporate effective tax rates (ETRs) summarising tax relief from investment tax incentives into comparable indicators. It presents ETR indicators for seven Sub-Saharan African countries. Empirical results show that tax incentives substantially lower corporate taxation across these countries. On average, tax incentives reduce ETRs by 30% in the food and automotive industries compared to the standard tax treatment. ETRs often differ among taxpayers in a same sector and country - by up to 55%. The most generous tax treatment is typically offered within Special Economic Zones, where tax incentives can reduce ETRs to near zero.
