The Subject-to-Tax Rule in East Africa: Is It Worth It?

The two-pillar approach focusses on BEPS issues in developing countries to a greater extent than preceding OECD agreements. In particular, the Subject-to-Tax Rule (STTR) is intended to address BEPS risks in low-income countries’ tax treaties. BEPS is undoubtedly a critical issue in East Africa since corporate income tax is an unusually important source of tax revenue in Africa. This article analyses the STTR alongside treaties and domestic law to understand the likely impact of the rule in the region. It also considers the diverse domestic policy landscapes to explore whether the STTR is an attractive measure for countries in East Africa. The author believes that implementation of the rule will be complex, challenging already stretched tax administrations. Furthermore, some low-income countries may prefer not to engage with reforms that increase source taxation. The analysis concludes that any hopes that the STTR will mark a major step in addressing BEPS in this part of the world are likely to be disappointed, but it could form part of a portfolio of measures for some specific countries.
