A tough call? Comparing tax revenues to be raised by developing countries from the Amount A and the UN Model Treaty Article 12B regimes

In this research paper, we attempt to estimate the tax revenues to be gained (or lost) by the South Centre and African Union's Member States under the Amount A and Article 12B regimes. Our analysis relied on sources of information available to private sector researchers but did not involve review of any information that taxpayers provide to tax authorities. Our research demonstrates that the comparative revenue effects of the Amount A and Article 12B taxation regimes largely depend on (a) design details of the Article 12B regime, (b) whether the country hosts headquarters of MNEs that may be in scope of Amount A or Article 12B taxation, and (c) what relief from double taxation, if any, the country will grant to domestic taxpayers subject to taxation under either the Amount A or Article 12B regimes.
