Tax Harmonization

As long as national tax systems develop in response to unique social and administrative pressures, jurisdictions will continue to rely on tax systems that exhibit at least as many differences as similarities. Tax harmonization represents the traditional answer to that entropic pressure, reflecting a confidence that nations can avoid international tax conflicts by becoming more like one another. Unfortunately, in part because many of the jurisdictions that populate today's international tax landscape have little in common, it seems that harmonization is no longer equal to the task. This Part introduces the concept of deharmonization, an alternative to harmonization that may be more robust.

African countries should consider alternatives to the arm’s length principle. A viable alternative to the arm’s length principle: the unitary taxation (formulary apportionment) approach should be considered. This approach looks in detail at the economic activities resulting into the profits of MNCs for tax purposes. Under this approach, tax authorities in Africa will justifiably impose corporate income taxes on “actual” profits of MNCs accruing form economic activities carried out in their jurisdictions, thereby eliminating the opportunities for base erosion and profit shifting in Africa.
