The number of super rich on the continent is growing fast. According to New World Wealth, the number of high-net-worth individuals (people with assets over $1 million) in Africa rose at twice the pace of the rest of the world in the past 15 years. Its 2016 Africa Wealth Report states there are about 165,000 high-net-worth individuals in Africa, with combined wealth of $860 billion. More ultra (with $30 million or more in assets) were created in Africa since 2003 than in any other region of the world. According to Wealth Insight, there are 1,932 in Africa.
But it is challenging for African governments to tax the wealthy.
Why collection is so hard
One of the reasons is the challenge of taxing income in economies that are highly informal. In Organisation for Economic Cooperation and Development countries, personal income taxes make up about a quarter of all tax revenue collected. In Africa, they only make up about a tenth on average, and as little as 4% in countries like Uganda and Rwanda. This is primarily – up to 95% – collected from employees of formal businesses through the pay-as-you-earn system. Self-employed professionals generally evade taxes and formal employees often engage in informal business on the side.
This informality contributes to African tax administrations lacking information on which citizens are high-net-worth individuals. In Kenya, only 100 high-net-worth individuals of a likely 40,000 are registered with the tax authority. In South Africa, up to 114,000 high-net-worth individuals are unregistered, costing the government about $10.9 billionin tax revenue.
It is also hard for African governments to tax the rich because they hide their wealth using the offshore financial system. Gabriel Zucman, from the London School of Economics, estimates that 30% of all African financial wealth is held offshore, amounting to about $500 billion. This means African governments are losing out on roughly $15 billion in taxes from individuals annually, and this does not take into account non-financial wealth. In 2015, Swiss Leaks revealed that HSBC Switzerland alone held more than $6.5 billion for clients from sub-Saharan Africa.
Uganda as a case study
A recent study undertaken by the Uganda Revenue Authority with support from the International Centre for Tax and Development, revealed the extent to which the political and economic elite evade taxation in Uganda.
The researchers examined lawyers from top commercial law firms and found that out of a group of 60, only 12 had paid personal income tax in 2012, and only 13 did the following year. The team also investigated individuals who paid large import duties. They found that although 12 people paid more than $180,000 in customs duties in 2014, none of them had paid personal income tax.
The researchers also investigated the links between government officials, business and tax compliance. Looking at a group of 71 high-ranking government officials owning large business assets (like hotels, schools and media houses), they found that only one had ever paid personal income tax between 2011 and 2014. Further, the companies the officials were associated with were largely non-compliant, with 47 out of 56 not paying any corporate income tax in 2013.
Increasing tax compliance among the wealthy is challenging because economic elites have great political influence. They are also often members of the political elite. In Kenya, for example, the government tried to implement a capital gains tax on the sale of property and shares, but was forced to scrap it due to resistance from business.
Uganda tried to introduce a system requiring income tax clearance from people buying land valued over $18,000 in 2011. This was also stopped due to political pressure.
Still, great progress is possible. Spurred by the results of the study mentioned above, the Uganda Revenue Authority established a high-net-worth individual unit in September. The new unit has been a significant success, raising an impressive $3.3 million in revenue by February.
Although enforcing tax compliance among the rich can generate significant additional revenue, what is at stake is much greater. The injustice of those with the most money not contributing to the public purse erodes the legitimacy of the whole system, leading those with less to feel even less willing to comply. As Ugandan researcher Ronald Waiswa said: "If you let the big crocodiles swim freely, the small fish will follow."
