Several economists and a report by the IMF (Digitalisation and Taxation in Asia) suggest developing countries may not have much to gain in revenue under the current form of the framework, which only covers top 100 companies under Pillar-1. IMF has estimated that emerging markets would lose revenue or have a modest revenue gain.
While it is a good initiative to estimate the revenue from Pillar One, I fear your reference is not to a report, but to a blog based on outdated data. We have estimated conservatively, based on the elements of the current negotiations and up-to-date data, that developing countries are expected to gain revenues from both pillars and we have communicated the results to the relevant countries. For Pillar One, developing countries are expected to gain an additional 1% of corporate income tax (CIT) revenues, on average. On Pillar Two, the minimum tax is expected to increase developing country revenue by approximately 1.5-2 per cent of CIT revenues on average.
