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 proportional to...

This paper investigates business tax compliance in a multilevel tax structure with limited coordination. We study the case of Kampala, where firms are taxed at national and local levels—by the Uganda Revenue Authority and the Kampala Capital City Authority, respectively—and where the agencies...

Uganda has one of the lowest corporate income tax collection rates in sub-Saharan Africa, while offering generous corporate tax incentives. It is unclear whether tax incentives achieve their objectives without primarily benefiting firms, potentially undermining domestic revenue mobilization and...

We investigate how the arrival and expansion of mobile network access in Uganda influences firm tax behaviour. Access to mobile technologies could broaden government revenues from corporate income tax through the extensive margin: by reducing the costs of formalization, it could increase the number...

The reform increased the tax-free lower threshold, increased tax rates...

We use income data from tax registers at the Uganda Revenue Authority from 2011 to 2017 to estimate top income inequality, focusing on the very top—the top 1, 0.1, and 0.01 per cent of the income distribution. The focus on the extreme top is facilitated by access to population data on formal sector...

The reform increased the tax-free lower threshold, increased tax rates for higher incomes, and introduced an additional highest tax band. Using the universe of pay-as-you-earn administrative data submitted by...
