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...

This paper identifies and analyses some key challenges that OECD and partner economies may face over the coming 50 years if underlying global trends relating to growth, trade, inequality and environmental pressures prevail. For example, global growth is likely to slow and become increasingly...

How much companies pay in corporate income taxes is often better captured by effective tax rates (ETRs) rather than by statutory ones. Economists further distinguish between those modelled using the law - forward-looking ETRs - and those estimated from actual data on companies' profits and taxes...

This paper documents the rise of corporate tax-base narrowing measures in the EU using a novel dataset covering both tax rate and tax base reforms implemented between 2014 and 2022. Our findings indicate a shift away from the ’cut rate – broaden base’ approach, as governments increasingly...

Effective tax rates (ETRs) estimated from the balance sheet data of multinational corporations (MNCs) are useful for comparing MNCs' corporate income taxation across countries. In this paper we propose a new methodological approach to estimate ETRs as reliably and as for as many countries as...

We develop a new methodology to decompose the observed decline in multinational corporations' (MNCs') effective tax rates into profit shifting to tax havens and several other components. We apply this methodology to the best available data for MNCs headquartered in the US - from the Bureau of...
