This paper simulates the impact of the global minimum corporate tax rate (GMCTR) in Uganda by estimating the difference between the mechanical and the behavioural changes in tax revenue. Overall, implementation of GMCTR will increase tax revenue, and the revenue increase is inversely...

The problem of debt bias can be tackled through either disincentivizing the use of debt financing or incentivizing the use of equity financing. Considering the South African context - in which many firms are highly leveraged and the marginal effective tax rates for using debt financing are...

We investigate the relationship between the corporate income tax burden and firm size in South Africa using a panel dataset from companies' tax returns. We find that medium-sized companies are experiencing the lowest effective tax rate, while the smallest companies are facing the highest...

Governments' revenues are lower when multinational enterprises avoid paying corporate income tax by shifting their profits to tax havens. In this paper, we ask which countries' tax revenues are affected most by this tax avoidance and how much. To estimate the scale of profit shifting, we start...

International corporate tax is an important source of government revenue, especially in lower-income countries. An important recent study of the scale of this problem was carried out by International Monetary Fund researchers Ernesto Crivelli, Ruud De Mooij, and Michael Keen. We first...

This paper conducts an impact evaluation of the effects of two tax administration interventions-a taxpayer register expansion and education programme, and a new electronic filing system for presumptive tax-on the number of small business taxpayers and presumptive tax revenues in Uganda. Using a...

Robust forecasting of mining sector revenues is key to effective budgeting (and broader fiscal management) in many resource-rich countries. However, this is challenging in practice, given commodity market volatility, the extended lags (and often opaque processes) between resource discoveries and...

Assessing tax gaps-the difference between the potential and actual taxes raised-plays a vital role in achieving positive domestic revenue objectives through improved and reformed taxation. This is particularly pertinent for growth outcomes in developing countries. This study uses a bottom-up...

Changes in the tax structure and category of taxes clearly matter when it comes to initiating tax policies. This paper employs data from a sample of 33 transitional countries over the period 1991-2014. It finds that, in a particular transitional country, the higher the national income, the...
